What We Do

Comprehensive Crawl Space Encapsulation Solutions in Bloomington, IL

Every Bloomington, IL Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.

Crawl Space

Standing Water Extraction

Before any liner goes down, we pump out existing standing water and remove debris left behind by prior drainage failures.

Crawl Space

12–20 Mil Vapor Barrier Liner

We install heavy-duty liner rated for crawl space conditions, sealed at every seam and pier to stop ground moisture from reaching the floor joists.

Crawl Space

Foundation Vent Sealing

Open foundation vents pull in humid outside air, which is often the real driver of Bloomington, IL crawl space condensation — we seal them as part of encapsulation.

Crawl Space

Dedicated Sump Discharge

We route discharge lines well away from the foundation so pumped water doesn't just cycle back in.

Crawl Space

Insulation & Duct Sealing

Exposed ductwork inside an unencapsulated crawl space collects condensation, which we address by insulating and sealing ducts while the space is open.

FAQ

What Bloomington, IL Customers Ask Us Most About Crawl Space Encapsulation

What's the difference between a vapor barrier and full encapsulation?

A vapor barrier is just the liner on the ground; full encapsulation seals vents, walls, and often adds a dehumidifier for complete moisture control.

How thick should my crawl space liner be?

We'll recommend a thickness based on how the space is actually used, not just a default.

Do I need to seal my foundation vents?

In most Bloomington, IL climates, yes — open vents pull in humid air that undoes a lot of the benefit of the liner alone.

Will encapsulation fix a musty smell in my house?

Often yes, if the crawl space is the source — sealing and dehumidifying typically resolves musty odors within a few days of installation.

Can you encapsulate a crawl space with standing water?

Yes — we extract existing water first, then proceed with liner and vent sealing once the space is dry enough to work safely.

How long does crawl space encapsulation take?

Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
