Home mold removal services are costly, and the process is lengthy. Not to mention, the presence of mold in your home can lead to serious health hazards including allergies, asthma, wheezing and so forth. The best way to never have to use a home mold remediation specialist involves prevention.

How to prevent mold in your house

Here are some general guidelines to follow if your home is particularly susceptible to high moisture levels, or you live in a region where humidity is high. However, even homes located in drier climates can succumb to moisture problems:

• Homes with exposed crawl spaces present significant risk for mold growth. Installing a specialized sheet of polyethylene prevents moisture from seeping through it, and mold from frowing on the surfaces of the crawl space.

• Check the foundation, and ensure that it slopes away from the home so that ground water and rain doesn't move toward the home.

• The home's drainage systems should also slope away from the home. Runoff from gutters and downspouts put your home at significant risk for moisture issues — and mold growth.

• Use a dehumidifier in a damp basement to keep it dry.

• Keep storage items in check. When elements like clothing, paper or cardboard come in contact with moisture, they're likely to encourage mold to grow, too.

• Avoid carpeting areas like bathrooms or basements. Any moisture that soaks into them is difficult to dry, and mold loves to grow in carpeting.

• Make sure the venting for the clothes dryer is directed outside of the house, instead of sending warm, moist air back into the home. Vents for all exhaust fans in the home should do the same.

• Houseplants can also harbor moisture. If you have many houseplants around the home, combined with a few other moisture-producing components, they could be contributing to higher-than-necessary moisture levels.

• Always run an exhaust fan after showering or bathing to swiftly usher the moisture produced by these activities outside of the home. Lingering moisture contributes to mildew and mold growth in the corners and crevices of grouting, caulk and so forth.

• The simple act of cooking food on a stove can generate moisture, too. If you have a stove exhaust fan, always run it while cooking, and for several minutes thereafter. If your home doesn't have an exhaust fan in the kitchen, consider installing one.

• Periodically check hidden areas for plumbing leaks. Pools of water left unchecked are quick to grow mold. When you do find water leaks, fix them immediately.

Stop mold growth to avoid home mold removal costs

Mold in the home poses significant risks to more than your health. It can also lead to time-consuming and costly household mold remediation.

If you discover mold in your home, contact a certified mold removal specialist to safely and quickly resolve the problem.
