Crawl space encapsulation that protects your home from the ground up

An open, damp crawl space affects your air quality, energy bills, and floors above. Encapsulation solves all three.

Overview

What you need to know about Crawl Space Encapsulation

Your crawl space has a significant impact on the rest of your home — and most homeowners never think about it. An unencapsulated crawl space allows moisture to migrate upward through the home, contributing to musty odours, mold growth, increased heating and cooling costs, and damage to floor joists and subfloor. Encapsulation seals the crawl space completely with a heavy-duty vapor barrier, conditioning it so it no longer acts as a source of moisture and energy loss. This offer connects you with crawl space specialists who assess your specific situation and install a lasting solution.

Common questions answered

Crawl Space Encapsulation — questions people actually ask

What is crawl space encapsulation?

Encapsulation seals the crawl space from ground moisture and outside air using a heavy-duty vapor barrier on the floor and walls, combined with drainage, insulation, and dehumidification as needed.

How is encapsulation different from a basic vapor barrier?

A basic plastic sheet on the ground is a vapor barrier — it reduces ground moisture but leaves walls open. Full encapsulation seals the entire crawl space, conditions it, and turns it into a semi-controlled environment.

Will encapsulation stop pests?

Sealing the crawl space significantly reduces pest entry points. Most specialists also seal vents and gaps in the foundation wall as part of the project.

How long does the installation take?

Most residential crawl space encapsulation projects are completed in one to two days depending on size and conditions.
