Why Choose Us

Why Richwood, NJ Property Owners Choose SGP Waterproofing for Crawl Space Encapsulation

Richwood, NJ 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 Richwood, NJ Crawl Space Encapsulation Work

Every Richwood, NJ 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 Richwood, NJ 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

Crawl Space Encapsulation Questions We Hear Every Week

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?▼

In most Richwood, NJ 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.
