Crawl Space Solutions

The part of your house nobody wants to look at.

Encapsulation, drainage, insulation and dehumidification — turning a damp crawl space into a dry one that stops damaging the house above it.

Encapsulated and sealed residential crawl space

Why crawl spaces matter more than people think

In this part of Tennessee, a huge share of homes sit on a crawl space. That open, vented, dirt-floored space under the house is where a lot of expensive problems start — and where they can be stopped cheaply.

What a wet crawl space does

  • Raises the humidity in the house, which makes your air conditioner work harder all summer
  • Feeds mold and wood rot on joists, subfloor and sill plates
  • Attracts pests, from termites to snakes
  • Creates the musty smell that follows you around the house
  • Softens the soil under your footings

What encapsulation looks like

We clean out the space, address drainage and any plumbing leaks, then seal the floor and walls with a heavy vapor barrier that's mechanically fastened and taped. Vents get sealed. Insulation gets replaced properly. Most jobs include a dehumidifier.

The honest version

Not every crawl space needs full encapsulation. If yours is dry and well-ventilated, I'll say so. If it's wet, doing nothing gets more expensive every year.
