insulation

The house we purchased in Mississauga had a poor layer of insulating stuff. I've found "Great Northern Insulation" company in internet. Mike came at the same day I called, made the estimation and scheduled the date of work. All was done exactly as promised, quickly and with the excellent quality. Now I'm paying for heat significantly less than before. Good work, guys!

foam insulation, thermal barrier

Everyone was very courteous and polite and friendly. The job itself was well done in the end. However, there seems to be a lot of miscommunication in their office. We got a bit of conflicting information. We booked our foam insulation more than a month in advance. I spoke to Jason the scheduler. On the day of the foaming, the insulators told us that the "second crew" would have to come out a few days later. Maybe we were naive but it was never explained to us that the process would take multiple appointments. There was a bit of panic on our end thinking we had to clear out the pets and ourselves for another toxic installation. Luckily the thermal barrier is non toxic. But we were not happy that this was never explicitly explained to us. The installation was on a Friday (my dad took a vacation day to stay at the house, with a respirator, while they did their work). The next Tuesday I had a call from accounting asking for payment for the foam and thermal barrier. I told them the thermal barrier hasn't even been done yet and I was waiting on a call to schedule that. I was told they do not work on weekends. So I booked them for the next day to come at 7:30 am. I usually leave for work at 7:30 but told work I would be a little late (I was originally told that the thermal barrier would take "maybe an hour"). Then later I was told it would take 3 hours but that this was "high balling" it. 7:30 rolls around and no one is at my door. I called their office at 7:45. The scheduler called me back and said that the crew would be an hour late because they had to load a new truck. I was a bit upset that they didn't bother to call me to tell me that they would be late, instead I had to initiate the call. So they arrived at 8:30 and the crew was very nice and they did their work but of course weren't done until after 11am. There was also conflicting information between the crew and our sales guy as to what needed to be done in the crawl spaces. By this point I had missed half a day of work. Good product and pretty nice people, but they are lacking in customer service skills and I just really think they need more communication within their office.

Attic Insulation

I needed to re-insulate my attic. A contractor recommended them to me. When I called, Jeff was prompt and provided the best solution for my budget. Two weeks after the job was completed.
Thank you.

Add insulation to attic to bring up to R50

Moving into my house, I discovered the attic only had about R20 insulation in the attic. Since that is where most of your heat loss is, I decided to get quotes to add insulation to R50. Great Northen submitted a quote and given their price and the reviews I read, I decided to go with them. That is one of the best decisions I have ever made. They went above and beyond my expectations and I would recommend them to anyone, and believe me, I'm fussy. This is a company that sure knows how to give customer service. I particulary want to thank Ben Mendonca, Ross Martin and Dave Rocha and Bernie for their great work and assistance. Also, thanks Susie for your help.

Attic Insulation Upgrade

Our garage door torsion spring broke after 8 years and we needed a replacement and All City Garage Doors did a great job with this replacement. It's a very dangerous DIY so we decided hiring a professional was the best way to proceed. Very happy with the work done and the service received was professional and done up to standards one would expect.

insulating basement and attic

I purchased an old house (built in 1945) that had very little insulation in the attic and none in the basement. I was fortunate to qualify for the energy audit under the full program so a year after I moved in I had arranged for Great Northern Insulation to come out for an estimate.

I had estimates from 3 other companies but the representative from GNI was the most knowledgeable and helpful plus their price was very competitive.

They arrived on time and I was pleased with how quickly the job went. They increased the insulation in the attic from its original R20 value to R50 and did a great job of cleaning up the mess. At the same time, another crew was in the basement putting spray foam insulation in the headers and on the walls. Again they did a great job of cleaning up afterwards.

I would not hesitate to recommend them to anyone looking to add some warmth to their home. It has made a huge difference in my heating costs and it is so much cooler in the house in the summer.

R12 to R50

I had Peter come by while I had my retrofit grant open in 2009. Price was right, they came when they said, did a great job and cleaned up after themselves.

They were truly a joy to deal with.

Attic Insulation

Looking for putting up insulation on the roof and found this company in home stars. They are not the cheapest but seems have good review. Come to my house the next day for estimate, even though not decide to use them, the guy has been very friendly and gives a lot of advice and good answers. The job is done in quality. Came 2 days as they did not bring enough fiber glass, but they make sure the job is well done. Clean up properly and house is very warm now.

Attic Insulation

Fibreglass insulation blown into attic over existing insulation to achieve R50 value. Crew arrived on time and were very considerate, they worked well, explained what the process involved and cleaned up afterwards. Would definitely recommend Great Northern Insulation
