That training is why our encapsulations solve the humidity problem permanently instead of just covering the dirt floor.
Fast scheduling matters here specifically because untreated crawl space moisture actively damages floor joists the longer it's left alone.
Encapsulation is priced by your actual crawl space square footage and drainage condition — quoted after a real walk-through, not a phone estimate.
We install a minimum 20-mil reinforced polyethylene liner — thick enough to resist tears from stored items or foot traffic, unlike the 6-mil sheeting sold at most hardware stores.
Every Crawl Space Encapsulation job starts with a real inspection — here's what that can include depending on what we find.
We install a 20-mil reinforced poly liner across the entire crawl space floor, running it up the foundation walls to the sill plate and sealing every seam — creating a continuous barrier between the ground and your living space.
Support piers and ductwork get individually wrapped and sealed rather than draped over, which is where most DIY encapsulations fail within a year. This is why our encapsulations hold up years after the crew has left the property.

Sealed vents only work safely alongside a dehumidification plan, which is why we never sell vent sealing as a standalone service. We won't call a job finished without it, even if it adds a little time to the visit.

The discharge line routes water well away from the foundation, and the pit lid is sealed to keep the encapsulated space airtight. This is why our encapsulations hold up years after the crew has left the property.

We size the unit to your actual square footage and ceiling height, not a generic one-size-fits-all model. We won't call a job finished without it, even if it adds a little time to the visit.
📞 Get a Free Quote →Before encapsulating, we probe exposed floor joists and sill plates with an awl to check for soft, rotted wood — because sealing over existing rot just hides an active structural problem.
Any rot findings are documented with photos and a repair recommendation before we proceed with the liner. This is why our encapsulations hold up years after the crew has left the property.

Crews reach most Clio properties within days of the call, carrying full encapsulation equipment so the assessment can move straight into scoping if you're ready.
Your technician enters the crawl space, checks for rot, standing water, and existing vapor barrier condition, then quotes a fixed price by square footage on-site.
Once approved, we install the full system — liner, sealed vents, dehumidification, and drainage if needed — and hand you a written warranty on the liner and seams.
"Previous owners had put down some thin plastic that was basically decorative at this point. Full encapsulation with the thick liner and a dehumidifier — floors upstairs stopped feeling cold within two weeks.Should have done this the day we moved in."
"Could see mold starting on a couple of the floor joists when we bought the house. They caught early wood rot during the walk-through before sealing anything, which we appreciated — no surprises hidden under the liner.Completely different space down there now."
"Musty smell used to hit you the second you opened the basement door, and it was actually coming from the crawl space below. Sealed vents, new liner, dehumidifier tied to a drain — smell's completely gone now.Should have done this the day we moved in."
"Had standing water under the house every spring. They put in a low-profile sump before encapsulating so it wasn't just sealing over a wet problem. Been dry under there through two full rainy seasons now.Completely different space down there now."
