Why Contractors Subcontract Basement Insulation
Basements are prone to moisture, temperature swings, and air leaks, making proper insulation essential. Contractors subcontract to Soundseals because we deliver:
-
Expert installation using the right materials for walls, rim joists, and crawl spaces
-
Code-compliant work that meets Ontario Building Code standards
-
Inspection-ready performance that passes on the first attempt
-
Reduced call-backs and long-term homeowner complaints
Subcontracting basement insulation ensures your team can focus on framing, electrical, and finishing, while we handle this critical component efficiently and professionally.
Spray Foam & Radon Gas Protection
Radon gas is a naturally occurring gas that can enter homes through cracks in foundation walls, floor joints, and utility penetrations. Because basements are below ground, they are the most common entry point.
Spray foam helps reduce radon infiltration by:
-
Sealing foundation cracks and seams
-
Blocking air pathways from the soil
-
Creating an airtight barrier around basement walls and rim joists
While spray foam is not a radon mitigation system by itself, it significantly reduces the pathways radon uses to enter the home, improving indoor air quality and supporting a healthier living environment.

Client Testimonial
"When we were doing a major renovation of our home, which was built in 1964, we found that the basement concrete block walls had moisture issues. We had Soundseals spray foam these walls to solve the problem.
Now, about 8 years later we are very happy the moisture problem was solved."
