How to avoid mold in your basement

How to avoid mold in your basement - Image 1

Avoiding mold in your home is difficult. Whether it lives on the bottom of your shower curtain or the floors of your basement, battling mold in your home is practically synonymous with being a homeowner in the Pacific Northwest.

It might be a common problem, but you shouldn’t settle for having mold in your home. If you suffer from allergies or asthma, mold can easily make you sick. Even if you’re not allergic to mold, it can still irritate your nose, throat, eyes, and skin.

Fortunately, there are ways to prevent mold in your home, especially in your basement.

1.  Invest in a dehumidifier

As its name suggests, our SaniDry dehumidifiers reduce humidity, which in turn makes your home less vulnerable to mold, dust, and mildew. Along with health benefits, dehumidifiers can lower your energy costs by allowing your air conditioner to run more efficiently when removing warm air from your home.

2. Create barriers for your basement walls

Mold grows on organic surfaces that are prone to moisture, which is why basement walls are more vulnerable. By installing a barrier like our VaporLoc Elite®, your walls are protected from mold and odor, as well as insects who are attracted to cold, wet environments. Our VaporLoc Wall System® prevents water vapor from passing through your foundation walls, directing it to your sump pump.

3. Have full peace of mind by completely waterproofing your home

Installing a SaniDry dehumidifier and VaporLoc Elite® are an excellent start to keeping your home free form mold. To gain full peace of mind, you might want to consider installing a complete basement waterproofing system.

Our WaterGuard® drainage system is the ideal choice for waterproofing your basement. This interior drain is designed to be installed below the floor slab, resting on top of the foundation footing. The WaterGuard®  installation requires minimal invasion to your slab, and all concrete is restored afterward.

Our TripleSafe Sump Pump collects any groundwater before it threatens your home with water damage. The primary pump in the TripleSafe Sump Pump can discharge 2,200 gallons of water per hour, and the secondary pump can remove nearly 4,000 gallons of water per hour! Your basement is wholly protected with our Sump Pump.
