Our Crawl Space Encapsulation Process

01

Inspection & Assessment

We inspect the crawl space for existing moisture, mold, insulation condition, and structural issues to develop a complete encapsulation plan.

02

Preparation

Existing vapor barrier (if any) is removed, debris is cleared, existing insulation may be removed and replaced, and any mold is treated.

03

Liner Installation

A heavy-duty (20 mil+) polyethylene liner is installed across the floor and up the walls, sealed at seams and to the foundation walls with tape and adhesive.

04

Conditioning

A dehumidifier, conditioned air supply, or exhaust fan is installed depending on whether the space will be conditioned or ventilated.

Crawl Space Encapsulation FAQ for Pittsburgh Homeowners

How often should Pittsburgh homeowners get crawl space encapsulation?
Given Pittsburgh's 161 cloudy days per year — one of the cloudiest us cities, most homeowners benefit from crawl space encapsulation at least once a year. Hillside retaining wall and drainage inspection after winter often makes spring or fall the optimal time to schedule service.
What home types in Pittsburgh most need crawl space encapsulation?
Brick row houses on Pittsburgh's famous steep hillsides and Victorian homes in Squirrel Hill, Shadyside, and Oakmont are the most common home types in Pittsburgh and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Why does it matter if my crawl space is damp?
Up to 40% of the air in your living space migrates up from below. Moisture and mold in the crawl space directly affects your indoor air quality, energy efficiency, and the structural integrity of floor joists.
What's the difference between a vapor barrier and full encapsulation?
A vapor barrier is just a ground cover liner. Full encapsulation covers all surfaces (floor, walls, piers) with a heavy-duty liner, seals all penetrations, and controls the humidity with a dehumidifier.
How long does encapsulation last?
A properly installed 20-mil liner lasts 20–30+ years. The dehumidifier needs periodic maintenance and eventual replacement. The system as a whole requires minimal ongoing attention.
Will encapsulation fix my musty basement smell?
If the smell is coming from the crawl space, yes. Encapsulation and humidity control eliminate the mold and moisture causing musty odors that migrate upward.
