Crawlspace Encapsulation Gatineau
Crawlspace encapsulation seals your crawlspace with a commercial-grade vapor barrier and dehumidifier — stopping moisture, mold, and pests at the source and protecting the air quality of your entire home. Gatineau's humid continental climate, high water table in low-lying areas, and Canadian Shield geology create challenges with moisture, drafts, and radon — especially in older homes in Hull and Aylmer. Quebec's building code now requires radon rough-ins in new construction, but most existing homes have no protection.

Crawlspace Encapsulation Gatineau — 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.
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.
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.
