Why Choose Us

Why Port Jefferson, NY Property Owners Choose SGP Waterproofing for Crawl Space Encapsulation

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

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

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

The Full Scope of Our Port Jefferson, NY Crawl Space Encapsulation Work

Every Port Jefferson, NY 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

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

Open foundation vents pull in humid outside air, which is often the real driver of Port Jefferson, NY crawl space condensation — we seal them as part of encapsulation.

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

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?▼

In most Port Jefferson, NY 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?▼

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?▼

Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
