Integrity Insulation were so professional and efficient. They took out the old rotted insulation, even from the attic door!! They blew in quality R rated insulation in a matter of hours. But what astonished me was the crew, didn’t just leave it at that! They actually vacuumed up any residual from my floors...who does that? My husband and I are so grateful for their professionalism. And the price was more than fair. thank you Mark!

They are flexible with scheduling and a pleasure to work with on the phone. Their installation team is fun and light hearted but always professional. I will continue using their spray foam team in the future!

Integrity insulation added insulation to all attics in my 4 split home. They were very friendly, answering any questions I had. They were considerate when my baby was sleeping to not make too much noise. And at the end, the quality of work was good and they cleaned up afterwards nicely which was very appreciated!! I highly recommend Integrity Insulation and am happy with their work. Thank you!

R-value is a measure of how well insulation resists heat flow—the higher the R-value, the greater the insulating power. In Ontario’s climate, choosing the right R-value is essential for maintaining energy efficiency and indoor comfort. Different areas of a home require different R-values (e.g., attics typically need higher R-values than walls). At Integrity Insulation, we help you select the appropriate insulation type and R-value to meet building code requirements and maximize long-term energy savings.
