Why Choose Us

Four Reasons Our Crawl Space Encapsulation Clients Don't Call Anyone Else

A rushed encapsulation job with unsealed seams or unwrapped piers looks fine on day one and fails within a season. We treat seam sealing and pier wrapping as core parts of the install, not optional add-ons that get skipped to save time.

1

Certified Encapsulation Installers

Every crew member is trained specifically on liner installation, seam sealing, and vent encapsulation, not general basement work.

2

Rapid Local Dispatch

Our technicians carry encapsulation materials on the truck for most standard-size crawl spaces, cutting down on return visits.

3

Flat-Rate, Square-Footage Pricing

Pricing is based on your crawl space's actual square footage and condition, quoted in writing before liner installation begins.

4

Dehumidification & Humidity Testing

We measure relative humidity before and after installation to confirm the space is actually staying below the threshold where mold and wood rot take hold.

What We Do

What Our Crawl Space Encapsulation Service Actually Covers

Every Lewistown, 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 Lewistown, 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

We also check subfloor insulation for water damage and replace anything compromised before closing the liner.

FAQ

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

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

We can scope either option depending on your budget and how severe the existing moisture problem is.

How thick should my crawl space liner be?▼

Most residential spaces do well with a 12-15 mil liner; spaces used for storage or with foot traffic often need 20 mil for durability.

Do I need to seal my foundation vents?▼

Some jurisdictions have code requirements around vent sealing, which we'll flag during the inspection if relevant.

Will encapsulation fix a musty smell in my house?▼

If the smell persists after encapsulation, that usually points to a separate moisture source we'd need to investigate.

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.
