Blown In Attic Insulation

I was scheduled to have the insulation installed on a Wednesday morning. When at noon no one had arrived I called the office. There was no one available to speak to. Finally at about 3:30 pm I got a call saying there had been issues and that they would come first thing Thursday morning. At noon no one had shown up so I called the office. No one was available. Then at about 3:30 I got a call saying they could come at 5:00 pm. I said fine, come. At 4:30 pm I received another call saying there was another issue, they were not coming. On Friday they called me to arrange to come on Monday afternoon, which they did. Then the blower broke down and a replacement truck had to be called in. The job that was supposed to take less than 2 hours took 5 days and 4.5 hours (the installers themselves were great). The company offered me a $100 discount and we settled with a $150 discount. It was a lot of inconvenience and I would have been far more satisfied if the company had made an effort to explain their situation and keep me informed about the delays How hard can it be to call the customer and give a reasonable explanation for the difficulties the company is having. Instead, I had to hound them!

Blown attic insulation install

Professional and easy to do business with. Straightforward process and timely execution through scheduling of estimate to completing the work(adding additional blown insulation in attic). Took steps to protect the room where they entered the attic and cleaned up afterwards. Flexible payment options.

crawl space spray insul.2700

the guys were very efficient , timely , and professional. the work done and the timing gets a 10/10 for this job . however , part of the job was to remove and haul away the old insulation. they did this but put very little effort into clean-up when the job was complete. i had to ask them to please do a quick sweep before they left. the one fellow then did this but broke the lightbulb off in the fixture. there was no offer to go in and replace it even though i said that i would get another bulb. i was the last job before the weekend so i guess they were in a hurry to get on the road. it was only about 2:30

Ceiling insulation.

Residence is 39 years old with original insulation...nothing added over the years. Took advantage of promotion and GNI contacted us to set up appointment. The team of 3 showed up at the time expected and they went right to work. Worked steadily until blower developed a bit of problem. Promptly fixed and back to work. Done at 2:20 and everything puts away and tidied up. Very pleasant guys...Tom, Bill and Sal. Temp in attic space was over 45 degrees C!
Very happy with the work done.

Thanks

Miscellaneous work

They fixed our garage door opener that was not working, fixed a ceiling fan that wasn’t working right, built a new platform for my washer and dryer to raise it up higher, patched a bunch of holes in the wall and put on two doorknobs. They also did some heavy lifting for me to take things outside. I had them over for a day. They were very professional, personable, helpful, punctual, reliable, and friendly. The price was kind of a sliding scale thing based on the number of hours, so it averaged about $90 an hour. The guy was pretty much able to handle everything. I went with him to a retail outlet to pick up stuff, and he helped me out there, which I appreciated. He seemed to work really quickly to get everything done, and I had no problems at all. I would rate them highly and would use them again in the future if necessary.

Blown in insulation above 3 bedrooms in Briar Hill Alliston

Sales Rep , Angelo Gabriele, recommended increasing from R40 to R60 levels with cellulose blown in loose fill and changing the in roof venting with better quality air vents . Tom and Brian , installers, did an excellent job in putting down cardboard and blankets to contain any dust build up when installing vents and blowing in the insulation. House was vacuumed and tidied up very well. The bedrooms and house in general is much cooler than previously on very hot days. The temperature balance between floors is significantly closer than earlier which means less electrical and gas bills . Win-win for GNI and us.

Attic Insulation Upgrade

Hired company through Costco. The experience was very positive from the time we booked a visit for an estimation to the actual installation. The whole process took a week. The sales consultant Glenn was very thorough in explaining the process and was very forthcoming in answering any questions. He was also very prompt in answering voice mail messages. The installers Tom/ Jefferson TYGNI were punctual, very pleasant and very helpful in answering any questions. They completed the installation on time and cleaned up nicely after installation.
All in all a very pleasant experience.
