Services
Cellulose Insulation
Our cellulose insulation provides superior thermal performance using recycled materials. Ideal for new constructions and retrofitting older homes, this solution reduces energy costs while maintaining environmental sustainability. The dense-packed method effectively fills cavities without structural damage.
Fiberglass Insulation
We install high-quality fiberglass batts and rolls for comprehensive thermal and acoustic control. This cost-effective option works particularly well in accessible attics and unfinished walls, offering excellent fire resistance and long-term durability.
Cavity Filling
Specializing in cavity wall insulation for older homes, we use precision techniques to fill hard-to-reach spaces without damaging existing structures. This service dramatically improves energy efficiency in heritage buildings while preserving their original character.
Attic Re-insulation
Our attic insulation solutions create effective thermal barriers in existing homes. Using non-invasive methods, we upgrade insulation levels to modern standards, significantly reducing heating and cooling costs while improving year-round comfort.
Basement Insulation
We specialize in basement insulation that prevents heat loss and moisture issues. Our approach maintains structural integrity while creating more comfortable living spaces and reducing energy consumption through improved thermal regulation.

Report
Art offered a quick reasonable quote, was a straight shooter, and did the work without any issues for adding additonal attic insulation. He came as a referral through a mutual friend, and I would recommend him myself now.

Art has a ton of experience and is great to deal with. They did a second job for me recently, insulating the extension of my house. Again: on time, on budget. I have a very old house and also very much appreciate the time Art has taken to explain to me what can be done, what needs doing.

Report
Art Mackay and his team did a great job on our insulation of our 1919 Ottawa home,Immediately after he left we noticed how much more comfortable our 2nd floor was, Very happy with all aspects of the work performed! Nice to deal directly with the owner-no wonder he was so highly recommended.
