Services
Insulation Installation
We provide professional insulation installation for residential and commercial properties. Our services include cavity filling, attic re-insulation, and basement insulation using high-quality cellulose or fiberglass materials. This improves energy efficiency, reduces noise transmission, and lowers heating/cooling costs while maintaining structural integrity through minimally invasive techniques.
Cellulose Insulation
Our cellulose insulation solutions offer superior thermal performance and soundproofing. Made from recycled materials, this eco-friendly option is ideal for both new construction and retrofitting older homes. The dense-packed method ensures even coverage in walls, attics, and hard-to-reach spaces without damaging existing structures.
Fiberglass Insulation
We install fiberglass insulation in batts or loose-fill forms for comprehensive temperature control. This cost-effective solution works well in standard wall cavities and attics. Our certified technicians ensure proper R-value achievement and safety compliance during installation to maximize energy savings and comfort.
Attic Re-insulation
Specialized attic re-insulation services address heat loss and moisture issues in existing homes. We assess current insulation levels, then install additional cellulose or fiberglass to meet modern efficiency standards. This process significantly reduces energy bills while maintaining attic storage functionality and structural safety.
Cavity Filling
Our cavity wall insulation fills empty spaces between walls with high-density materials. This technique improves thermal efficiency in older homes without altering exterior appearances. Using precision equipment, we inject insulation through small drilled holes that are later sealed, leaving minimal visible disruption to walls or finishes.

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.

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.
