Dehumidification & Humidity Testing

What We Do

The Full Scope of Our Lawrenceville, IL Crawl Space Encapsulation Work

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

Crawl Space

Standing Water Extraction

Extraction equipment includes submersible pumps sized for tight crawl space access points.

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 Lawrenceville, 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

Frequently Asked Questions 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?

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?

Spaces with extensive prior water damage or debris may take longer — we'll give you a realistic estimate up front.
