Crawlspace Encapsulation
Seal out moisture, mold, and pests with a professional vapor barrier system that protects your home from the ground up.
What Is Crawlspace Encapsulation?
Your crawlspace directly affects the air quality, structural integrity, and energy efficiency of your entire home. Up to 50% of the air on your first floor originates from the crawlspace below — meaning mold, moisture, and radon down there end up in your living space.
Encapsulation seals the crawlspace with a commercial-grade vapor barrier across the floor and walls, closes vents and air leaks, and adds a controlled dehumidifier. The result is a dry, clean, conditioned space that stops moisture problems at their source.
Common Questions
What is crawlspace encapsulation?
Crawlspace encapsulation is the process of sealing your crawlspace with a heavy-duty vapor barrier across the floor and walls, sealing vents and air leaks, and often adding a dehumidifier. This creates a dry, conditioned space that protects your home from moisture, mold, and pests.
Why should I encapsulate my crawlspace?
An unsealed crawlspace allows moisture and humid air to enter your home, leading to mold growth, wood rot, higher energy bills, and poor indoor air quality. Up to 50% of the air you breathe on the first floor comes from your crawlspace.
How long does encapsulation last?
A professionally installed encapsulation system with a quality vapor barrier and dehumidifier can last 15–20 years or more with minimal maintenance. We use commercial-grade materials designed for long-term performance.
Will encapsulation help with radon?
Yes. Sealing the crawlspace floor and walls reduces radon entry points. For homes with elevated radon levels, we can combine encapsulation with a radon mitigation system for comprehensive protection.
