Air-Drying Systems for Your Williamsburg, VA Crawl Space

Moisture in your crawl space can result in serious consequences for your home’s maintenance, air quality and energy efficiency. Even though these issues are occurring underneath your home, they can still affect the rooms where you live and breathe. Your family and your home deserve to be protected from mold, fungus, mildew and wood rot.

Problems under the house can stem from condensation, rain or high humidity in the summer, all common in Virginia. No matter what the concern, a dehumidifier may not do enough to keep out water in crawl spaces. Tidewater Insulators is the answer for how to fix the problem of a wet crawl space. When it comes to drying out crawl spaces, you can trust our years of experience to protect your home and your family.

How Crawl Space Fans Work

If you are asking “do crawl space ventilation fans really work?,” the answer is yes. As part of one of our crawl space air-drying systems, these fans draw out moisture from wood and insulation and maintain the proper moisture level in your home to prevent the growth of mold, mildew and fungus below your home.

Tidewater Insulators’ system of exhaust fans creates negative pressure, which prevents crawl space air from entering your home. Additionally, vent covers keep summer’s humid air from entering your crawl space. The result is no more moisture under the house and safer air to breathe where you live.

Benefits of Installing an Air-Drying System

In addition to protecting your home from wood rot, an air-drying system will save you money by reducing your heating and cooling costs. The vent covers that inhibit hot air from entering your home will also stop cold air, leaving the subfloor of your home cooler in the summer and warmer in the winter.

Also, our simple-to-install system is maintenance-free, and it adheres to green standards. Our systems have been specially engineered at a lower power usage, so they dry the air by producing high CFM and static airflow. Moisture is pulled out of the wood and insulation in your crawl space at the same level as other, less energy-efficient systems ― without running up your electric bill. Most of our systems only require simple GFI outlets installed in the crawl space and an on/off switch.
