Crawl Space Encapsulation in Toronto, GTA and Southern Ontario
Crawl space encapsulation is a full moisture-control system that seals your crawl space from the ground up—reducing humidity, musty odours, mold risk, and pest entry points. If your crawl space is damp, smells stale, or shows condensation and wood deterioration, encapsulation can help protect your home’s structure and indoor air quality.
What it is: A sealed crawl space system using a heavy-duty vapour liner plus air sealing and moisture control.
What it solves: Moisture, musty smells, mold conditions, condensation, and pest activity.
What’s included: Liner installation + sealed seams, sealing vents/gaps, and adding drainage / a sump / dehumidifier when needed.
Book a crawl space inspection with Dryshield and we’ll recommend the right fix based on what’s actually happening under your home.

What’s Included in Crawl Space Encapsulation
Encapsulation isn’t just laying plastic on the ground. A proper system focuses on sealing, controlling moisture, and keeping humidity stable.
Most encapsulation projects include:
- Heavy-duty crawl space vapour barrier / liner on the floor (and walls when appropriate)
- Sealed seams and penetrations (posts, pipes, corners, transitions)
- Air sealing at vents, gaps, and common leakage points
- Improved access sealing at the crawl space hatch/door
- Moisture-control upgrades as needed, such as:
- Crawl space dehumidifier
- Sump pump and drainage solutions
- Interior drainage where water intrusion is present
- Insulation improvements (depending on the structure and building design)
Benefits of Crawl Space Encapsulation
A properly encapsulated crawl space can help:
- Reduce musty odours and damp conditions
- Lower the risk of mold and mildew growth
- Protect wood framing from long-term moisture exposure
- Reduce condensation on pipes and fixtures
- Discourage insects and rodents by sealing entry points
- Improve comfort and energy performance in some homes (especially when drafts and humidity are reduced)
Crawl Space Encapsulation Cost (What Impacts Price)
The cost of crawl space encapsulation depends on what’s happening underneath your home and what’s required to control moisture long-term.
Key pricing factors include:
- Crawl space size and height/access difficulty
- Amount of ground moisture and whether water intrusion is present
- Whether you need drainage or a sump pump
- Whether a dehumidifier is recommended
- Condition of materials (e.g., rotted wood, damaged insulation, heavy debris)
- Complexity of sealing around posts, pipes, and tight sections
