Crawlspace remediation & encapsulation

Dry it out, then seal it shut.

A wet crawlspace does not stay under the house. It rots joists, warps floors, and drives up humidity in the rooms above. We fix the source and seal the space so it stays dry for good.

Know the signs

What a failing crawlspace looks like upstairs.

Most homeowners never go under the house. These are the signals that the crawlspace is the real problem.

Musty, damp air

A smell that will not clear and humidity that lingers in the rooms right above the crawlspace.

Sagging or bouncy floors

Floors that flex or slope because the joists below have taken on moisture and lost strength.

Sagging insulation

Batts hanging loose or fallen to the ground, soaked through and no longer doing their job.

High energy bills

Heating and cooling that works harder than it should because the envelope leaks air through the floor.

Standing water or stains

Pooling water, mud, or dark water lines on the piers after it rains, and rust on anything metal.

Pests getting in

Open vents and gaps that let rodents and insects into the crawlspace and up into the home.

Before and after

From wet and open to dry and sealed.

What encapsulation includes

A complete seal, not a patch.

  • ✓Clear out and clean upRemove debris, standing water, and failed insulation so we can see the real condition.
  • ✓Correct the moisture sourceGrading, drainage, and any leak that is feeding water into the space, handled first.
  • ✓Full vapor barrierA heavy-duty liner across the floor and up the walls, sealed at the seams.
  • ✓Seal the vents and gapsClose the openings that let humid air, water, and pests into the crawlspace.
  • ✓Insulation and support as neededReplace failed insulation and reinforce joists or piers where the moisture did damage.

Scope

A written plan with photos and a firm price, before any work.

Dry out

Clear the space, remove water and failed insulation, fix the source.

Encapsulate

Vapor barrier down and up the walls, vents and gaps sealed.

Crawlspace questions

What is crawlspace encapsulation?+

It is sealing the crawlspace off from ground moisture and outside air. We lay a heavy vapor barrier across the floor and up the walls, seal the vents and gaps, and correct whatever was letting water in. The result is a dry, controlled space instead of an open, damp one.

How long does it take?+

It depends on size, how much water and debris we start with, and whether joists or piers need reinforcement. We give you the timeline in the written scope before work starts.

Do you fix the damage the moisture already caused?+

Yes. If joists, subfloor, or supports have been weakened, we reinforce or replace them as part of the repair, then seal the space so it does not happen again.

Do you handle active mold?+

We focus on the moisture repair and the structure. If there is active mold, we point you to a remediation specialist first, then encapsulate and repair once the space is clear.

Will this help with my insurance claim?+

It can. We document the damage and the scope of repair with clear photos and written detail, which is what most claims need to move.
