Root Causes of pests, mold, & odor
in your Crawl Space

Water that seeps into your crawl space can serve as a breeding ground for pests, mold, and odor. When it does, your quality of life suffers from poor air quality and inefficient heating to damage to property and your home. Crawl space encapsulation by TerraFirma can help you address these common issues.


Crawl Space Vents

Open crawl space vents are an invitation for moisture. This damp environment is a perfect incubator for wood rot, mold, mildew, and dust mites. You might notice higher electricity bills as a result of a failing crawl space vent. A professional inspection can identify whether your crawl space vents need to be repaired.


Exposed Ground

Exposed dirt in your crawl space absorbs odor and moisture like a sponge, and moisture from dirt can get trapped in a closed area like a crawl space. As the damp soil dries, a musty smell and damp air rise through your home to change the relative humidity. This can lead to mold, affecting the life and health of your loved ones


Compromised Subfloor

When wood floors warp, the problem might go all the way down to the subfloor. Water condensation and leakage can also seep through the crawl space to the subfloor. If your subfloor has been compromised, you might notice squeaky or bowed floors, which are not only unattractive but can also pose hazards to your family.


Damaged Foundation

Once your crawl space is wet, it stays wet. Prolonged exposure to moisture weakens the wooden beams that support your home, damaging and warping the structure. Water can seep into the cement of your home’s foundation, where seasonal freezing and thawing will form cracks. If you live in a flood zone or an area that gets a lot of rain, check your crawl space for signs of water at least twice a year and after storms and heavy rain.


Poor Drainage

Without a properly performing drainage system, water from your roof and gutters pours directly into the soil surrounding your home. Poor drainage in your crawl space can lead to expensive foundation repairs if not addressed promptly.
