What drives the price up?
- Square footage
- Wall height
- Accessibility (very short & tight crawlspaces increase work time)
- Extent of mold, damage, or standing water
What does an average cost home look like?
We are used to dealing with messy crawlspaces, so your home may not be as bad as you think. When we go into a problem crawl space we usually see:
- 1700 Sq ft.
- Crawlspace height of 3 ft.
- Mold scattered throughout the joists & subfloor
- Insulation falling or fallen in a couple of spots
- Water pooling in a couple of spots
Who doesn’t need a full crawl space encapsulation?
A full crawl space encapsulation is reserved for crawl spaces with mold throughout, wet joists, and high humidity. This means wood with a moisture reading over 19% and humidity over 60%. This environment fosters mold growth, so the conditions need to be addressed to prevent mold from coming back. If the wood and air in your crawlspace are dry, crawl space encapsulation may not be for you.
Other scenarios where encapsulation isn’t necessary include:
- Mold in one location due to a leak
- Standing water only (should be addressed by water proofing to prevent foundation damage)
