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

Sullivan, WI crawl space calls get scheduled fast, especially when there's standing water or an active mold smell involved.

3

Flat-Rate, Square-Footage Pricing

No hourly billing — the number we quote is the number on the final invoice.

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

What Our Crawl Space Encapsulation Service Actually Covers

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

Open foundation vents pull in humid outside air, which is often the real driver of Sullivan, WI 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

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?▼

In most Sullivan, WI 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.
