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

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

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

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

What Frenchtown, NJ 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?▼

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?▼

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.
