It seems like in the housing industry whenever someone says, “Mold”, there is an instant panic. Probably panic is not the best way to deal with mold.
There are a number of different types of mold; some are easy to eradicate, and, unfortunately, others aren’t. Knowing the differences, the remedies and the costs can let you determine if the house to want to buy makes sense, or should you look at others.
Not only is mold destructive to homes, but it can cause serious health issues. This is certainly something to have checked out by an expert.
We are fortunate to live in the Denver area where the climate does not promote as much mold as other areas of the country. I always tell my clients that if you can smell mold, there are issues. I also let them know that chances are mold is somewhere in every house. Preventing circumstances which will allow the mold to grow is how to control it.
What Causes Mold
Mold grows on plants and fibers. It digests the organic matter and then releases additional mold spores.
In today’s market, Denver houses for sale that have been unoccupied for any length of time can have serious mold issues caused by leaks in the roof, water leaking in the home due to improper water shut off, a leaking hot water heat and/or clogged gutters. Buyers need to be aware of such issues. A well-trained home inspector can help you identify these issues and give you information on the remedies.
Artificial stucco, also known as EFIS has become a mold issue. Moisture can seep between the stucco/siding and the interior walls. The mold spores will attach themselves to the wood used for the framing. You should 1) make sure the stucco is not artificial, and 2) if it is, have the home tested. Testing for mold can be fairly expensive. Contact an expert!
Improperly installed or damaged gutters can be a real culprit. If they become clogged with leaves the water runoff can seep into the basement and mold can start to grow on the framing. The sad thing is that a little prevention can avert a huge disaster and many homeowners are unaware.
In the Front Range area, many of the newer homes have started using structural basement flooring. This is a wood floor laid over a crawl space. When the foundation has been dug, a plastic sheeting material/water vapor barrier is laid down on top of the dirt, then the floor is laid over several feet of air space. Many times construction workers have left debris in the form of food behind and the food, as it decays, begins to generate mold which will then attach itself to the floor. Also if the structure is not well sealed, water from heavy rains or over-watering can seep into the crawl space. The best fix? Talk to an expert.

How to Control Moisture
There are a variety of things you can do to keep condensation at bay, and water out of your home.
Many every day things add moisture into the air. Cooking a big pot of pasta, showering and doing laundry can increase the moisture content.
1. Fix any leaks you may have in pipes in baths and kitchens. Check under the sinks on a regular basis to ensure all is dry.
2. Occasionally apply a slight pressure to the tiles around your bath tub and shower. If you feel a little give, call a plumber right away.
3. Check to make sure the flooring around toilets, showers and tubs has no give to it. If it feels a little spongy, call a plumber!
4. Use exhaust fans in the baths and kitchen area. These fans should vent to the outside, not your attic area.
5. Vent your dryer to the outside. If that’s not possible, use a fan to circulate the heat and moisture.
6. Changes in temperature can also cause condensation on windows. You will need add insulation and caulk around window sills.
7. Open doors in the house. Make sure there is adequate circulation. You may want to try fans when temperatures are extreme. Make sure that your heat vents are not covered by heavy furniture.
8, Dehumidifiers and air conditioners help. However, if they are not kept clean and in good working order, they, too, can become a source for bacteria and mold.
9. Make sure that your landscaping always slopes away from the house. Add additional soil, rocks, mulch, etc. to raise the level. Also, planting right next to the house is never a good idea.
10. If you run your sprinklers at night, once or twice during the season, run them when you can see them to ensure that they are not sending inordinate amounts of water toward the house and foundation. Check the drainage.
11. Add a vapor barrier and seal it in crawl spaces. You made need to add a fan if moisture is a problem.
12. Check the carpet in the basement periodically to ensure that it is dry. It is always a good idea to check near walls after receiving large amounts of rain or snow.
Don’t forget, that not all mold is bad – it gives us penicillin!
