On-Site Assessment & Code-Compliant Inspection
We visit your property to inspect your attic, basement, walls, or garage. We assess insulation quality, air sealing, moisture levels, and compliance with Ontario Building Code. This ensures a tailored solution and proper energy efficiency recommendations.
Transparent Quote & Clear Plan
You receive a detailed estimate outlining scope, materials, and R-value targets. No hidden fees, no pressure, just honest, expert advice to guide your decision.
Professional Installation
Our trained, insured team completes the job on time and to code. We use approved materials (spray foam, batt, blown-in) and follow best practices for vapor barriers, fire safety, and thermal resistance — fully compliant with Ontario requirements.
Cleanup, Warranty & Ongoing Support
After the work is done, we clean the site, walk you through the results, and issue a written warranty. We remain available for any questions and assist with rebate programs or future upgrades.
