Why Choose Us

Why Lafayette, OR Property Owners Choose SGP Waterproofing for Crawl Space Encapsulation

Lafayette, OR 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.

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

Every Lafayette, OR Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.

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

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 Lafayette, OR 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?▼

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.
