Why Choose Us

Why Deerfield, WI Property Owners Choose SGP Waterproofing for Crawl Space Encapsulation

Deerfield, WI crawl spaces vary a lot in how they were originally built, and a liner that's correct for one home can be undersized for another depending on foot traffic and storage use. We size thickness to how the space is actually used.

1

Certified Encapsulation Installers

We follow manufacturer specs on liner overlap and seam tape so the barrier actually holds up over time.

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

A dedicated crawl space dehumidifier is sized to your square footage, not a one-size-fits-all unit.

What We Do

The Full Scope of Our Deerfield, WI Crawl Space Encapsulation Work

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

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

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

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 Deerfield, WI 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?▼

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?▼

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?▼

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