Why Choose Us

Why Lockport, IL Property Owners Choose SGP Waterproofing for Crawl Space Encapsulation

What We Do

Comprehensive Crawl Space Encapsulation Solutions in Lockport, IL

We scope every Crawl Space Encapsulation job in person before quoting it, since two properties with the same symptom rarely need the same fix.

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

Liner thickness is selected based on foot traffic and how the space will be used going forward, not a flat default.

Crawl Space

Foundation Vent Sealing

Sealed vents are paired with mechanical dehumidification so the space doesn't just trap humidity instead of venting it.

Crawl Space

Dedicated Sump Discharge

A crawl space needs its own sump basin and discharge line separate from any basement system, since the two spaces drain differently.

Crawl Space

Insulation & Duct Sealing

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

FAQ

Crawl Space Encapsulation Questions We Hear Every Week

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?▼

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 Lockport, 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?▼

Standing water doesn't disqualify a space from encapsulation; it's just the first step in the process.

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.
