Spray Foam Insulation in Ottawa

In addition to more standard insulation practices, O’Reilly Brothers is also your source for spray foam insulation in Ottawa. Sprayed polyurethane foam offers many advantages when compared to other practices. As it’s sprayed, it expands, filling the space around it creating an air-tight seal even in hard to reach places. It provides insulation and acts as a barrier against air and liquids, making it extremely energy efficient. Spray foam is very tough and can last years after it is applied.

We had the pleasure to work with many wonderful clients. Here are some of their thoughts on our services.

“I would like to pass on my thanks to your crew for the great work they did on insulating the attic at my house. It was great from start to finish, beginning with Chris Auger, whose advice and knowledge was greatly appreciated. Chris is the most helpful estimator possible and as the person with whom we had the most contact, his presence was invaluable.

This is the second time that we have had your company handle an insulation job for us and it’s worth noting that when other contractors – roofers, drywallers and carpenters etc. knew we were having O’Reilly for this job, their response was, “the best in the city”.”

Keith, Customer

“It’s always a pleasure working with you and O’Reilly Brothers, we always know what high level of service we will be provided with. We know the work will be well done and the crews are always excellent.”

Dennis & Sally, Customers

“I highly recommend this company. They showed up on time, John and his team were very informative, professional and attentive to detail. They also were very attentive to respecting all safety issues and answering my questions. The company was also open to a small amount of price negotiation.”
