What Is Mold?
Molds are various types of fungi (singular = fungus) that grow in filaments and reproduce by forming spores that can travel through the air. The term mildew refers to some kinds of mold, particularly mold in the home with a white or grayish color or mold growing in shower stalls and bathrooms. Mold may grow indoors or outdoors and thrives in damp, warm, and humid environments. Mold exists in essentially any environment or season.
The most common types of household mold found indoors include Cladosporium, Penicillium, Alternaria, and Aspergillus. Stachybotryschartarum (also known as Stachybotrys atra and sometimes referred to as "black mold") is a greenish-black mold found indoors, although it is less common than the other types of mold found in homes. Stachybotrys grows on household surfaces that have high cellulose content, such as wood, fiberboard, gypsum board, paper, dust, and lint. There are types of mold that can grow on substances as different as foods and carpet.
Molds reproduce by forming tiny spores that are not visible to the naked eye. Mold spores are very hardy and can survive under conditions in which mold cannot grow, such as in dry and harsh environments. These spores travel through outdoor and indoor air. When the mold spores in the air land on a surface where moisture is present, mold can then start to grow.
Outdoors, molds play a role in the decomposition of organic material such as dead trees, compost, and leaves. They are most common in damp, dark areas or areas of decomposing plant life. People often find mold indoors in basements or shower stalls. Indoor mold in residential areas has the potential to cause health problems and can destroy surfaces and objects where it grows.
scented candles & spots
Black Soot Deposition: The Sinister Side of Scented Candles | Rainbow International Blog
Insurance and commercial property management companies have noted an increase in claims due to black spot stains on ceilings, walls, furniture, content and HVAC filters from previously unidentified sources. The problem is referred to as “black soot deposition” (BSD) and, as research indicates, it is frequently caused by a common household decorative item.
There is no evidence of a sudden or accidental source for BSD, such as malfunctioning furnaces, gas water heaters, cigarette smoke or cooking by-products. Until recently, there was little compelling evidence to assign proper blame for the source of BSD. Tests have confirmed, however, it is very possible decorative scented candles are a primary culprit.
Low-quality candles often to blame
Research indicates increased BSD is often the result of candle manufacturers adding additional fragrance oils to their products, along with improper wick trimming by customers. Many fragrance oils are not suitable for combustion and do not burn cleanly. It also appears that many amateur candle-makers have entered the expanding market to capitalize on the current popularity of candles without proper training or experience. The outcome is an abundance of low-quality candles burning in many homes and a corresponding increase in the frequency of indoor soot deposits.
Potential dangers to structure and health
The number of aromatic candle manufacturers, professional and amateur, grows each year. A number of these introduce candles to their product line without the knowledge necessary to produce a safe and clean-burning product. Chemical testing provides conclusive evidence that emissions from some burning candles contain more than twenty volatile organic compounds, lead and a significant amount of carbon.
Burning scented candles inside homes, apartments and commercial buildings can present serious health hazards to those living and working there. It can also mean damage to ventilation systems, furnishing and content. Evidence suggests breathing even one micron of particulate soot can be hazardous. The Environmental Protection Agency (EPA) and American Lung Association (ALA) have determined breathing particulate matter 2.5 microns or smaller is detrimental to human health. These particles are dangerous because they are inhaled deeply into the lungs, causing irritation and respiratory problems. Those at extra risk include people with heart or lung disease, children and the elderly.
Initial Signs of BSD
The first visible indication of candle soot deposits in a structure is often a dingy gray look appearing on light-colored upholstery or fabrics. Plastic items may accumulate a black film, electronic equipment shows discoloration near vents and a thin black residue develops on television and computer screens.
In homes, apartments and commercial buildings with wall-to-wall carpet, connections and door undercuts may begin to show dark spots or discoloration. Deposits can also be found on draperies, vertical blinds and bed ruffles.
Testing proves key in identifying primary source of BSD
To prove damage can result from such candles, testing was conducted in a model home in Florida. The structure was 2,800-square-feet and featured a central air conditioning system. Four candles were burned and the resulting soot deposits were so noticeable after just three days that testing was discontinued. Total candle-burning time was less than sixty hours.
An additional test was conducted in a 144-square-foot room using candles taken from the same model home. During the test, particulate levels rose above 11 million particles per cubic foot within thirty minutes.
The science behind BSD
When candle materials burn inefficiently, it is because combustion is incomplete. The resulting black soot is hydrocarbon-based. Candle soot production normally begins when the particulate matter produced reaches .06 to 0.1 microns in size. Soot adheres to plastic and optical devices because they are statically charged.
For soot deposits to accumulate, a driving force (i.e., gravity, electrostatic attraction or a forced-air unit) must be in place to push the particulate matter against a surface.
Over time, these soot particles unite with each other and with dust particles in the air. When this soot is released into the air of a building, it eventually deposits onto surfaces because of random collisions between particles. This effect is referred to as Brownian Motion (an assumed random movement of suspended particles). When these particles unite and grow in size, they gain enough mass to deposit via gravity.
If a homeowner, resident or business manager contacts you about these mysterious black spots, check the décor of the structure with an eye out for scented candles. They may help the air temporarily smell better but can also render it harmful to the building and its inhabitants.
Steps to help eliminate BSD
Begin by refraining from burning all candles. If possible, air-out the structure by opening windows. Inspect the air conditioner filter and, if necessary, replace it. Consider using a high-efficiency filter, like a charged media filter. For structural and content damage, call on an IICRC certified firm with experience in fire and smoke restoration.
Purchase quality candles (see below) and trim wicks properly (down to a quarter-inch after each burning). Burn candles for no more than an hour at a time and allow for cool-down period before re-lighting. Do not burn candles under a draft, like vents or near fans and heaters.

A good reference source for candle information is the National Candle Association, a group promoting safety, quality and industry standards. The website offers useful information, including a list of members that have pledged their professional commitment to quality candles and candle-making
Checklist for a stress-free moving day.
A Moving Checklist That Is Stress-Free | Rainbow International
Every move represents the closing of one chapter and the beginning of another. Sparky Anderson once said, “Good seasons start with good beginnings.” Now we’re pretty sure Sparky was talking about baseball here, but you can absolutely apply this quote to day-to-day life too.
A Moving Checklist That Is Stress-Free
Without a doubt, you want to start this new chapter in your life with a good beginning – and that means a stress-free move. We at SERVPRO want you to feel at home again as soon as possible. So, here is a moving checklist to help you have a stress-free move and get your new beginning started off right.
Go through and get rid of, sell or donate anything you haven’t used in the past year. Don’t waste your time packing it if you haven’t used it. And if there’s time, have a pre-moving sale. You’ll get a little extra pocket change to help with moving expenses.
Before you box up your electronics, take a quick picture of how everything is hooked up and connected. This will save you a major headache as you try to reconnect in your new home.
Use colored duct tape to label each box. Designate a color for each room in your new home. As you pack, put a piece of tape on the side of the box for easy recognition. All boxes with yellow tape will go to the kitchen; blue tape will go to the master bath…
Moving takes a lot out of you, and there’s a good possibility you may be too tired to get everything unpacked in one day. So, pack an overnight bag with your essentials. Make sure to include a change of clothing, medications and the basic toiletries you’ll need.
Make it Clear
Pack anything you will need right away in a clear plastic tub. This includes paper/plastic eating utensils, phone chargers, power strips, box cutters, paper towels, trash bags… You get the idea. The clear tub will easily stand out from the mountains upon mountains of cardboard boxes. Hopefully these tips will help you recover from the move a little easier. Happy moving!
How to remove cigarette smoke from your home
How to Remove Cigarette Smoke Odor in Your House.
Don’t let the stale odor of cigarette smoke contaminate your indoor air quality. Removing cigarette smoke demands patience – the acidic smoke leaves resins and tars that permeate everything in the vicinity.
The process for eliminating smoke odor in your house depends on the severity of contamination. If someone smoked inside for a decade, restoration may require a more invasive approach, such as throwing items out or even replacing the drywall and carpet. If the room smells like an ashtray, consider throwing out items that don’t have sentimental value – sometimes that overstuffed couch is just too smelly and not worth the time and money you would spend on restoring it.
SERVPRO has a few suggestions to show you how to remove cigarette smoke smell from your house. You might be able to eliminate the smoke smell with just a few of these tips, or the job may require a combination of several methods (and repetition) to remove the odor entirely.
Start with Hard Surfaces
Begin by opening all windows and doors to provide ventilation while you clean. Use a spray bottle and a rag to wipe down all hard surfaces with a 50 / 50 solution of white vinegar and hot water. You may also wash the walls and ceiling with a mixture of 1/2 cup ammonia, 1/4 cup vinegar, 1/2 cup baking soda and a gallon of hot water.
Leave no surface untouched: Clean walls, doors, knobs, light fixtures (bulbs too), ceilings, fan blades, and anything the smoke came in contact with. Wipe down all knickknacks, photo frames and decorations as well. Consider throwing out items such as lampshades and throw pillows that absorb odors well and are easy to replace. To reach high spots, use a ladder or an extension pole with a rag clamp.
Next, focus on fabric, carpet and upholstery – beginning with what you can’t throw in the washing machine. Sprinkle everything with baking soda, and let it sit for a few days. Once the baking soda has had a chance to absorb the odor, vacuum it all up and repeat as necessary. Then steam clean the carpets. If you don’t have a steam cleaner, you can buy or rent one at your local hardware store. If your steam cleaner has an upholstery attachment, use this to clean drapes or upholstered furniture too.
Wash your laundry-safe fabrics (couch-cushion covers, some drapes and curtains) in the machine with 1/2 cup vinegar instead of detergent. Follow up with another wash cycle with your preferred detergent. It’s best to let these items air-dry outside to prevent shrinkage.
Air Circulation & Purification
If weather permits, keep windows and doors open for as long as is practical. Use fans to encourage air circulation – have one fan blowing air from outside on one side of the room, and put another fan across the room to exhaust the air outside. An air purifier with a HEPA filter can help remove odor-causing molecules. If the odor remains after you air out your home, place activated charcoal or bowls of white vinegar (or even apple cider vinegar) around the rooms to absorb odors. Replace the charcoal or vinegar every few days. Be wary of scented “odor removal” products, which may just mask the smell instead of removing it.
Homeowners should also replace HVAC air filters. Your home’s air filters help remove odor-causing molecules, and they work best if they’re replaced every two to three months. Consult with the furnace or AC unit manufacturer to find a filter that may help with odor removal (e.g., charcoal or HEPA filters). You should also inspect your ducts for any dust or debris that may contain smoke molecules; this may be contaminating the fresh air in your home as it travels down your ducts. If you see buildup, hire SERVPRO to clean your ducts.
If smoke odor still lingers after you complete all these steps, an ozone generator is your next best option. Ozone is a powerful cleanser and is very effective at eliminating odors. Ozone generators create activated oxygen. By oxidizing the smoke molecules, they can eliminate the smoke smell entirely (if used properly). We SERVPRO can place ozone generators in your home for you. Which usually involve leaving the machine running in a closed room for a specific period of time.

PREVENT YOUR CAR FROM OVER HEATING
Park in the shade
You can feel the temperature difference between the shade and the sun – and so can your car. Parking in the shade not only keeps you cool, but can prolong the life of your car. No shady spot? Use a sunshade to reduce heat inside the car.
2. Tint your windows
A local dealership or auto body shop can apply tinted windows to help keep your car cooler, and protect your interior from sun damage.
3. Use a sun shade
Keeping a sun shade in the car is helpful because you can’t always guarantee that you’ll find a shaded or covered area to park in. These UV heat shields will keep the interior from getting super-hot, plus it protects your interior from the damaging effects of the sun. You might even consider getting a custom-made sun screen that is designed to fit your make and model of car. These special shades can be more effective at keeping all of the rays out.
4. Get rid of hot air
Closed windows trap hot air, and the glass serves as a conductor that helps heat up the enclosed space. Leave your windows open slightly so the air can escape – and if you have a sunroof, crack that, too. Make sure the opening is not large enough for someone to reach through. If you leave your windows cracked, remember to keep an eye on the weather – one sudden summer storm could lead to a soggy interior.
5. Turn the floor vents on
Most people get in the car and turn the upper vents on “high” to get the air flowing. But you’re actually better off directing the air through the floor vents. Hot air rises, so switch to the bottom vents and put your blower on the maximum setting to push that air out. Then, once the car begins cooling, you can open the upper vents again.
6. Use the fresh air setting on your A/C
Using the re-circulation setting means you’re just moving that hot, trapped air around your vehicle, so that’s something you want to use after your car has had the chance to cool down. Give it 10 minutes or so, then switch over.
7. Keep your eye on the temperature gauge
Located on the dashboard, the device has a needle that should always be pointing toward the center. If it points toward hot, pull over, turn off the engine and let the car cool down.
8. Turning on the heat
Turning on the heat may be the last thing you want to do on a hot summer day, but it can pull hot air from the engine compartment and cool the engine. It won’t fix the underlying problem, but it’s a good measure for long drives.
9. Add engine coolant
This is especially important in hot months. To check the coolant level, open the hood and locate the coolant reservoir. The coolant level is shown by indicator lines on the reservoir. If too low, simply add the appropriate amount of coolant and reattach the cap. Engine coolant is often sold as a 50/50 mix of water and coolant. You can also buy concentrated coolant and mix it yourself.
Safety tip: Never add coolant to a hot engine. Wait for the engine to cool before removing the cap or pouring in coolant.
10. Have your cooling system flushed by a mechanic
Even if you keep engine coolant at the right levels, it will eventually get dirty and need to be replaced. Flushing involves draining old coolant from the radiator, cleaning it with flush fluid and adding new coolant. Mechanics recommend a flush every 40,000 miles, but check your owner’s manual for the manufacturer’s recommendation.
11. Consider replacing your battery
If your car battery is older than three years, it may not be providing the power it once did, so your car has to work harder and can overheat. Your mechanic can help you determine whether you may need a new battery.
If you find yourself in a situation where your car overheats, follow these steps to ensure you and your vehicle remain safe:
- Pull over, park your car and turn off the engine as soon as possible. Let your car cool for a minimum of 10 minutes.
- Open the hood of your car to allow the heat to clear out quickly.
- Once your car has cooled off, turn the ignition to its first position (don’t start the engine). If you see that the temperature gauge is within a normal range and engine fluid levels are sufficient, try to start the engine.
- If the engine makes unusual sounds or it does not start at all, it’s best to stay on the safe side and call for roadside assistance to have your car towed. This will allow for a mechanic to inspect it and make the necessary repairs.
What can cause your car to overheat?
Hot temperatures alone might not be causing your vehicle to overheat. If your car’s cooling systems aren’t functioning correctly, it can lead to serious damage to your engine and expensive repairs. Here are a few common engine problems that can cause your car to run hot that you should know about:
- Coolant: Every car has a cooling system to help keep the temperature of the engine down. If your cooling system has a leak, blockage or pump malfunction, the coolant might not be able to circulate properly. Cooling system malfunctions aren’t just problematic when it’s hot out; very cold temperatures can cause coolant to freeze and prevent circulation.
- Thermostat: Another possible issue could be a problem with the thermostat. A vehicle’s thermostat is responsible for regulating the amount of coolant flowing through the engine. A broken or malfunctioning one can easily cause your car to overheat.
- Low Oil: A car’s oil does more than just lubricate moving parts. It also helps to remove excess heat from the engine. If your vehicle has low oil, it might be causing your car to run hot.
- Radiator Fan: If your cooling fan isn’t turning on or running at the right level, it can case your car to overheat. Radiator fans usually run on electric motors, so any motor mechanical problems can lead to your fan not providing enough cool air flow.
Of course these aren’t the only possible problems that can cause a car to overheat. It’s a good idea to find a reliable mechanic who can diagnose and service your car, and get protection in case your car overheats while you’re on the road.

FAMILY FUN FOR THE CAR RIDE
4 FUN FAMILY CAR GAMES TO SURVIVE A ROAD TRIP
If you’re a parent, the thought of a long summer car ride has the potential to strike fear in your heart. It’s not the traffic or cost of gas that’s scary. It’s the prospect of keeping the kids entertained for hours on end. That’s why having a few family car games ready to go can be a lifesaver on a road trip.
Here are a few car games for kids that can make the miles go faster and create a little family bonding in the process:
1. Barn, Bike, Beetle!
In this spotting game, the first person to spot a barn, a bike (your choice if motorcycles do or don’t count) and a Volkswagen Beetle wins. Change the spotting items to work for your surroundings.
One person says a word and the next person says whatever comes to mind. Continue around the car for as long as you’d like. For example, one player might say “blue,” causing player two to say “water,” leading the next person to say “beach house!” The beauty of the game is that there are no right or wrong answers, and everyone can play.
3. Twenty Questions
A classic family car game, Twenty Questions is a simple game that can produce hours of fun. Take turns thinking of some sort of object; it can be a person, animal, food and anything in between. For younger children, you might want to establish a certain category to make the game a little easier. Players then can get 20 yes or no questions to ask, and then have to guess the secret object.
4. I Spy
I Spy is a great car game for young children due to its simplicity. One person picks out something from the surroundings, and gives a hint. Everyone then takes turns guessing the mystery object. Don’t forget the signature phrase, “I spy with my little eye” before giving a clue!
While family car games can be a welcome addition to a road trip, safety always come first. Make sure whoever is driving maintains full focus on the road at all times and doesn’t get distracted by passengers playing a game. Here are more essential driving safety tips to keep in mind on your next road trip.
Don't Leave your best friend behind ! Traveling with pets.
Is your family pet joining you on summer vacation? Whether you’re traveling in trains, planes or automobiles, these helpful pet travel tips will help ensure smooth sailing on your journey.
Air Travel Restrictions
Many airlines have established travel restrictions for pets to ensure they are not exposed to extreme temperatures while in the holding area (which is not air conditioned), the terminal facility and when being moved between the terminal and the aircraft. Ask your airline of choice if they have a summertime travel embargo preventing pets from flying during the months of May through September.
Arrival, layover and departure airports that have a temperature above 84 degrees will not accept pets. For brachycephalic dog’s breeds (including pugs, Boston terriers, boxers, bulldogs chow chows, some mastiffs, Pekingese, pit bulls, Lhasa Apso’s, Shar-Peis and Shih Tzus) and snub-nosed cats (Burmese, exotics, Himalayans, Persians, British shorthairs and Scottish folds) that restriction is 75 degrees.
Consider a red-eye flight or an early morning departure when temperatures are cooler. Try to avoid layovers, if possible. If your pet is traveling in the cargo bay, choose early morning or late evening flights to avoid extreme temperatures that may affect your pet’s health.
Air Travel Policies
Before booking your ticket, call the airline to make sure you have a clear understanding of their pet policy to avoid any complications upon your arrival at the terminal. This includes necessary paperwork for your pet, crate size requirements and other details. Not only may there be restrictions based on seasonal temperature and types of breeds traveling, some airlines also impose age restrictions.
Delta Airlines announced in December 2011 that they were no longer permitting pugs or snub-nosed cats to board as cargo on any flights. Make sure your pet will be welcome on board the airline of your choice before you commit to purchasing a ticket that may be nonrefundable.
Avoid the Holiday Rush
If traveling during the summer holidays, try leaving a day or two before and after the main rush, and use direct flights whenever possible to avoid accidental transfers, delays or, worse, a displaced pet. Space for small pets permitted in the cabin is limited, so book early.
Pet Lodging Permitted?
If you’re taking a road trip get prior confirmation from hotels and camp sites that your pet is a welcome guest. Don’t presume that information in a brochure or on a Web site has the most up-to-date information.
Usually, hotels have a limited number of pet-friendly rooms which can book up quickly during summer months so plan your trip ahead of time to secure a place for you and your companion.
Don’t Leave Home without These
- Don’t forget to bring your pet’s essentials:
- Litter box/poop bags
- Food, water and treats*
- Food and water dishes
- Leash or harness
- A couple favorite toys
- Pet health certificate (required by airlines, some hotels)
- First-aid kit
- Sunscreen and insect repellent for pets (check with your vet)
- Any necessary medications
- ID tags
- If traveling on an airplane, tape your pet’s picture to the outside of the kennel along with your contact info
*Always bring enough food for your pet plus two extra servings just as a precaution. It’s not ideal to switch up your pet’s diet while you’re traveling as that can lead to an upset stomach and diarrhea.
Prepare Your Pet for a Healthy, Safe Trip
A few useful tips before you hit the trail:
- The USDA asks that pets be given food and water four hours prior to check in at the airport. If you’re traveling in a car, avoid feeding pets one hour prior to your road trip to avoid motion sickness.
- Use car safety restraints to protect your pet in case of an accident.
- Don’t ever leave your pet unattended in a hot car. As little as a few minutes in a hot car can result in a catastrophic, life threatening situation.
- Consider a checkup with your pet’s veterinarian prior to any travel to make sure your pet is up to date on vaccines and is in good health. The airline will require proof of this as well.
PLACES TO CHECK FOR MOLD GROWTH IN YOUR HOME
Do you know where to look for Mold? Just hearing the word can cause us all to cringe. It’s odorous, unsightly, and dangerous to our health. And it can show up so fast that it can be shocking! The top three places to look and check regularly are the Bathrooms, Kitchen and Laundry Area. Please practice preventive measures, it can help avoid mold and give you a peace of mind.
The bathroom. Since we all know that mold likes water. Water is everywhere in a bath area. Most bathrooms are cleaned thoroughly at least once a week, and these times are great for checking for mold. Look in the least traveled areas, such as corners of the linen closet, behind the toilet, under the sink. If there are, or have been, any leaks in these places in the past, these areas are in danger until they are fully dry. You can invest in a dehumidifier for your bathroom, and that can be a great help.
The kitchen. Another area of your home that has a lot of water, and it is used more than any other area in the house besides the bath. Keep an eye out for spills and leaks and clean them up immediately to ensure that they are not attracting mold spores, which are always in our air and cannot be removed. The trick is not giving them a place to land and settle!
The laundry room. This room, since it has large appliances, also has nooks and crannies that are not cleaned as often, since no one ever sees them. Add to that the humidity in the air and possible unseen leaks or drips, and you have a recipe for the establishment of a mold colony. Get help to pull the washer and dryer out from the wall regularly, and make sure the areas behind them are clean, dry, and disinfected. Make sure spills are cleaned and dried right away, as well.
Other areas to keep an eye on: hall closets, your garage, and/or basement.
