Our encapsulation system

The full encapsulation system.

A sealed envelope from floor to rim joist — vapor barrier, drainage, sump, dehumidification, sealed access. We install only what your crawl space needs. Bespoke, full, not piece-mealed.

01

Heavy vapor barrier

Sealed over floor, walls, and piers — blocks soil moisture and humid air from rising into the home.

02

Perimeter drainage

Channel 58 around the footing collects water that gets past walls and routes it to the sump.

03

Workhorse sump pump

Sealed-lid sump removes collected water — pairs with optional battery backup.

04

HumidiGuard dehumidifier

Sized to your crawl space — controls humidity to target range, drains into the sump.

05

Sealed crawl access

Insulated, gasketed access door — finishes the envelope so outside humidity stays outside.

FAQ

Crawl space questions.

Why encapsulate instead of just laying a plastic vapor barrier?
A loose plastic sheet won't seal at walls, piers, or seams — humid air and soil moisture keep moving through. Full encapsulation seals the entire crawl space (floor, walls, piers, rim joist) and is paired with dehumidification to actually control conditions.
Will encapsulation eliminate the musty smell upstairs?
Most of the musty smell upstairs comes from the crawl space via the stack effect — air rises through floors. Sealing and dehumidifying the crawl can dramatically reduce conditions that produce odor. Severe mold may need remediation first.
Does crawl space encapsulation help with energy bills or floor temperature?
A sealed crawl space can help moderate humidity and reduce conditioning loads — floors above often feel warmer in winter and less sticky in summer. Energy savings depend on the home's HVAC setup, insulation, and existing leakage.
Do I need mold remediation before encapsulation?
Sometimes. If visible mold or active microbial growth is present on joists, sheathing, or insulation, we recommend remediation before sealing. The inspection determines whether remediation is needed and what the right scope is.
How long does crawl space encapsulation take?
Project duration varies by crawl space size, condition, and scope (whether drainage, remediation, or insulation work is included). Your written plan includes a timeline specific to your home.
What does the warranty cover?
Our crawl space work is backed by product-specific written warranties. Term and transferability vary by component (vapor barrier, drainage, sump, dehumidifier) — the exact terms are included with your install paperwork and reviewed during the inspection.
