    Attic insulation, Basement insulation, weather stripping door

    Great Northern Insulation did an AMAZING Job in my home! From the moment that Dan contacted me I was treated with the utmost expertise and respect. He was very knowledgeable in providing me with information regarding my attic and basement insulation, as well as the weather stripping on my door. His team of Tim, Michael and AJ arrived on time and were very diligent in the set up of the equipment and material to do the job. They were efficient, thorough, knowledgeable and respectful! They were mindful to set up and do the job without any damage to the property as well as cleaning, putting back everything in its place and vacuuming my home! Great job Dan, Tim, Michael and AJ! Great Northern Insulation is a GREAT and Reputable Company!

    Attic Insulation has made this summer bearable

    I had an asbestos scare and I felt terrible for the men who noticed it in case they were exposed, however, they were very professional and came back once the coast was clear! Thanks Manpreet, Navjot, and Parminder for your fine service and excellent efficiency with my attic insulation job on one of the hottest days of the summer. 32 degrees! We are all cooler here now.

    Additional attic insulation

    I was very pleased with the service provided by Great Northern Insulation in Nepean, ON. The service providers, Manpreet and Charnjit, were efficient, knowledgeable, tidy, and did an overall great job. Likewise, the sales rep, Harley, was knowledgeable and booked things quickly. I would definitely recommend GNI Nepean.

    Poor Customer Service

    I chose Great Northern based on the reviews I had seen online. Unfortunately, we made a mistake - this is the only contractor I have ever hired that I regret choosing. The customer service is terrible. It seems to be a big organization that works in silos. The only bright spot was the sales representative - he was knowledgeable and thorough.

    Thank you for taking the time to review our services, despite the fact that overall we did not meet your expectations. We'd like to investigate your issues further but are unable to do so without a cu…

    Attic Insulation

    We had our Attic Insulated by Great Northern Insulation (Milton) and we were very impressed by the Professional and hard working team that did the job! Gurvir, Jermain and Zeki were very knowledgeable and made sure that we were satisfied before they left. Zeki explained the type of insulation used the benefits and Gurvir showed us before and after photos and explained what the job entailed. Excellent Team!

    Answer from pro:

    Thank you very much for your review! We're glad to hear that your installation team met or exceeded your expectations. Thanks again!

    Spray foam bay windows

    GNI spray foamed the basement headers and bay windows. They had to come back as the window installer noticed insufficient thickness in spray foam. Even with this return, the rooms are colder than before with drafts! Very disappointed with the quality of this work!!
