Great Northern Insulation

Great Northern Insulation came to our cottage on Lake Erie to spray foam the underside of the house. The crew faced a nasty job. The outside temperature was -4C, the ground was frozen, and before they could spray they needed to remove old fiberglass insulation that housed a dead raccoon, a live raccoon, and a bee hive. The crew worked through the challenges with professionalism and diligence. We are very satisfied with the work completed and now find the cottage much, much warmer and not at all drafty as it was before. I would highly recommend Great Northern Insulation for a spray foam job....we are glad we had the work done. Thanks to the crew, and to Jason in scheduling who worked with us in getting the crew out when the weather co-operated.

The salesman, Aaron, answered all questions at the appraisal and later by e-mail; the team showed up on time, very professional and curteous, did a great job; the R62 insulation makes a big difference. Highly recommended. Thank you, Aaaron, Tim and Ben!

The installers arrived on time and did there best to minimize mess and keep as much heat in the house as possible during the install (the install was during winter.)

While preparing the attic the installers noticed that at some point in the past that an animal had been nesting in the attic however but that it had apparently been cleaned up/kept out properly so I shouldn't worry to much.

Once complete they asked if I would like to inspect the work and assisted me in getting up the ladder to view the work. They then removed there equipment and cleaned up all of the loose insulation that happened to be around. The estimate was exactly on target as was the number of bales they expected to use.

We hired this company to insulate our basement. They were excellent. They arrived on time and were very professional. We had some concerns with a section and they returned and added more insulation to that section within a few days no questions asked. We would definitely hire them again in the future.

We moved into a new home and called Great Northern Installation Services to insulate our home for us. We chose them because they were recommended to us by a close family friend. They did a great job and were very quick and clean. Overall, an excellent job!

We've now used Great Norhtern for insulation jobs on two houses; each time they have listened to our requests, carefully inspected the areas that required work, given us helpful advice, and even talked us out of getting some of the work done, as it would not be cost effective for us. Both times their quote was lower than most others, and when they arrived to do the job they were courteous, quick and tidy. They were excellent, and I would fully recommend them.

We had fibreglass batts as insulation and it was becoming a mess as a result of animal nesting and genrally poor installtion. We hired GNI to remove the old insulation and install polyurethane foam. They were recommended by a competitor who doesn't have the equipement for this type of job as there are lots of irregualr surfaces. They removed a lot of materials that the fibreglass was behind and installed the foam carefully and precisely and cleaned up the old material. However, they ripped apart many surfaces and as a policy left them open with removed materials in a pile - which the salesman had not expected to happen. We had it repaired and things now are fine.

We've recently had our attic insulated through GNI and are very impressed with the overall quality of service and product. Peter has been exceptional at answering all of the many questions we had about insulation and GNI's product. The young men that came to do the work were very professional. I highly recommend GNI!

They are very thorough. They did not leave a mess. They did a bit more than was required. Peter Brenner was friendly and knowledgable and only focused on what had to be done. The workers that actually did the job was also good.
