  • Dirt Crawl Space with Trapped Moisture in North Wales, PA
    Dirt Crawl Space with Trapped Moisture in North Wales, PA

    This dirt crawl space was in poor condition when the BQ Basement Systems experts first got a look at it. They came up with a plan to tightly seal the space with our CleanSpace Encapsulation System. CleanSpace is a thick white liner that keeps out moisture, pests, and humidity. In addition to the barrier, a sump pump was also put in place. This will collect any water that may accumulate, and expell it from the basement, out of the space and away from the homes foundation.

This installed improved the health of the crawl space, thus improving the overall health of the home.

Mold in Your Crawl Space?

To survive, mold needs three things: some warmth, organic materials to eat, and a relative humidity of 60% or higher.

Mold is very tolerant to heat and cold — it grows in refrigerators, and it will certainly survive in your crawl space. Mold can also survive by eating just about any organic material, including wood, fiberglass resins and paper backings, cardboard, dust, and organic materials in soils.

However, mold has one important weakness: it needs lots of humidity to survive. BQ Basement Systems can eliminate mold growth by sealing off the crawl space vents, installing a plastic vapor barrier on the walls and floor, and running a dehumidifier in the space.

Sources of Crawl Space Moisture & Mold

Natural Sources Man-Made Problems
  • Groundwater leaking into the crawl space from the ground below
  • Water flooding in through the crawl space vents and pipe penetrations
  • Water vapor entering through your dirt or concrete walls and floors
  • Failing overworked dehumidifiers
  • Plumbing leaks or sewage leaks
  • Failing water heater leaks

We stop the problem by eliminating what helps mold grow! Call today to schedule your no cost, no obligation estimate for your dry, mold-free crawl space!

Wet, Leaking Crawl Space?

crawl space drainage system and pipe

The SmartPipe™ Crawl Space Drain is compatible with the CleanSpace® crawl space system for a dry crawl space!

If you have a wet, leaking crawl space, it will affect your entire home. The best way to dry a flooded crawl space is to install a crawl space sump pump and crawl space drainage system, to collect the water and discharge it from your home through a discharge line.

At BQ Basement Systems, we also recommend installing SmartPipe™, the first custom-engineered crawl space drainage system designed just for crawl spaces. SmartPipe™ is specially designed to collect crawl space groundwater and direct it to the sump pump system.


Protecting your Crawl Space from Humidity and Water Vapor

Damp Crawl Spaces Can Lead To...

- Rotting crawlspace wood/timber
- Odors rising from the crawlspace
- Mold spores in the home
- Increased chance of termites/ants
- Higher cooling & heating bills
- Loss of crawlspace as good storage space

Once your crawl space drain has been installed, it's a good idea to protect your home further with a crawl space vapor barrier, along with airtight crawl space vent covers and doors. 

At BQ Basement Systems, we provide the CleanSpace® Crawl Space Encapsulation system, including our 20-mil thick crawl space liner which carries a 25-Year Warranty.
