Muskoka Thermal Coatings
DC315 Thermal Barrier Specialists · Muskoka, Ontario
The Short Answer
DC315 thermal barrier coating in Muskoka typically costs between $2.50 and $3.50 per square foot, with a minimum service fee of $1,500 regardless of project size.
For most residential applications, total project costs range from $1,500 (minimum for small spaces) to $4,000-$6,000+ for large or complex jobs.
What Factors Affect the Price?
1. Total Square Footage of Exposed Foam
The single biggest driver is how much foam surface needs to be coated. This is measured in square feet of foam surface area — not floor area. A basement with spray foam on four walls, the ceiling, and rim joists will have considerably more surface area than the room's footprint suggests.
2. Project Complexity and Access
Tight crawlspaces, low ceilings, obstacles like mechanical equipment, and awkward angles all affect application time. A 600 sq ft crawlspace with 30-inch clearance takes significantly longer to coat than 600 sq ft of open basement wall.
3. Prep Work Required
If the foam surface has significant debris, contamination, or sections that need masking, additional prep time is required.
4. Travel Distance Within Muskoka
We serve the full Muskoka region. Travel time is factored into the project quote for more remote locations.
5. Minimum Service Fee
Regardless of project size, the minimum service fee is $1,500. Very small applications (under approximately 400 sq ft) will hit this minimum.

Local Insight
The most common pricing question we hear is: 'Can I just paint over the foam myself?' The answer is no. DC315 must be applied at specific thicknesses using commercial spray equipment. Standard paint or hardware store intumescent coatings do not meet the DC315 standard and will not satisfy a building inspector.
