Professional Spray Foam Installations in Downtown Toronto, Ontario

Downtown Toronto winters drive stack-effect air leaks through rim joists, garages, and rooms over garages. We install closed-cell spray foam (≈R-6–R-7 per inch) where moisture resistance and structural rigidity matter, and open-cell foam where sound control and value are the priority. All installs follow Ontario Building Code requirements for ignition barriers and ventilation.

Why Spray Foam Works Best in Downtown Toronto

Downtown Toronto’s winters amplify stack-effect leaks and condensation. Closed-cell foam stops air and moisture where it matters; open-cell adds sound control and value inside. Here’s where spray foam outperforms other options in Downtown builds:

Ice/condensation control in garages over living space

Closed-cell foam creates a continuous air & vapour barrier in garage ceilings/bonus rooms to prevent frost and dripping.

Rim-joist air sealing to stop drafts

Spray foam seals rim bays where most houses leak, cutting cold floors and stack-effect drafts.

Basement thermal break to dry up cold walls

Closed-cell foam adds R-value and moisture control on foundation walls for warmer, drier basements.

Metal/warehouse shells in the downtown core

Spray foam cuts heat loss and air leakage in commercial shells and workshops—reducing gas and electric spend.

FAQ — Spray Foam in Downtown Toronto

Straight answers to what homeowners and facility managers ask us most.

Do I still need a vapour barrier?
Closed-cell typically meets vapour-barrier requirements at thickness; open-cell does not. We specify thickness to Ontario code and apply ignition barriers where required.
How long before I can re-enter the space?
Usually 24 hours after application with ventilation running. We’ll confirm on-site based on foam type and airflow.
What R-value should I expect?
Closed-cell ≈ R-6–R-7 per inch; open-cell ≈ R-3.6–R-3.8 per inch. Air sealing from foam often saves more energy than R-value alone.
Can you spray over existing batts?
We remove wet/compromised insulation at problem areas and prep clean, dry substrates for proper adhesion before spraying.
Will it reduce noise?
Open-cell helps with airborne sound between rooms; closed-cell adds rigidity and is best for air/moisture control.
What affects cost the most?
Foam type, inches applied, square footage, access/containment, and any required ignition or vapour barriers.
Warranty?
Written workmanship warranty plus manufacturer material warranty. Full terms are included in your quote.
What is spray foam used for?
Creating an air, vapour, and thermal barrier in attics, rim joists, basements, crawl spaces, garages, and metal buildings. Closed-cell also adds structural rigidity and moisture control.
Is spray foam illegal?
No. Spray foam is code-approved in Ontario when installed by qualified contractors to manufacturer specs, with required ignition barriers and ventilation. Problems come from improper DIY installs.
How much does it cost to spray foam a 24×24 garage?
Ballpark ranges vary by foam type and inches. In the GTA, a 24×24 garage commonly prices from $3.5k–$6.5k for closed-cell (walls/ceiling, 2–3"), less for open-cell where appropriate. Get a site quote for exact scope. Prices are indicative and may change with thickness, access, and fire-barrier requirements.
Why are some people removing spray foam insulation?
Usually due to bad installs: wrong mix/temperature, spraying over wet substrates, wrong thickness, or missing ignition/vapour barriers. Properly installed foam is durable and typically not removed.

Julia P. · Liberty Village (Rim Joists)

Closed-cell on the rim joists made an immediate difference in our loft—warmer floors and no more drafts by the stairs. Crew contained everything and cleaned up perfectly.

★★★★★
Ryan C. · Leslieville (Flat Roof Deck)

5.5" closed-cell at the roof deck—no ice issues last winter and the top floor holds temperature. Quote was accurate and the team was professional end-to-end.

★★★★★
Nadia S. · St. Lawrence / King East (Basement)

3" closed-cell on our foundation walls dried out the basement and cut the musty smell within days. They walked us through code and ignition-barrier requirements clearly.
