Do I need a Full Encapsulation Or Partial Encapsulation?
Full Encapsulation
We always recommend a full encapsulation when mold & fungus is present throughout the crawl space, but why do we recommend it? It’s because its the only way we can guarantee your crawl space will stay clean and dry. When we do a full encapsulation we put a vapor barrier on the ground to stop moisture form rising up out of the ground, and we install wall blankets to insulate your foundation walls. It’s the best way to insulate your space.
Think of it this way: If you we’re to build a home, would you not insulate your walls to save money in the short term? Probably not. Skipping wall insulation would lower your cost when you built the house, but your home would be less comfortable and your HVAC would be working harder in the long run. Even though a full encapsulation is an investment, its the right way to protect your home..
Partial Encapsulaton
A partial encapsulation is a way to save money on encapsulating your crawl space. It’s the same as a full encapsulation, but it saves money by skipping the wall blankets. Instead, we add what’s called a dimple matt on your walls that directs any water intrusion under the vapor barrier on your ground. You’re probably wondering if you can just do a partial encapsulation for your home. Afterall, it is a cheaper option.
Partial encapsulations can work, but your dehumidifier will be working harder to condition the space. Because the walls aren’t insulated, humid air will more easily enter the space. The blankets we install on a full encapsulation add an R-value of 11 to your foundation walls. For context, your foundation walls provide almost no insulation.
Partial encapsulation can work, but we can’t guarantee the effectiveness because it skips a crucial step.
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)
