Basement Spray Insulation

I had my basement outside wall headers sprayed approximately 4 years ago. Besides the headers the crew sprayed over all pipes and conduits in the way and completely sprayed over waterlines that the basement heat kept them from freezing. Other arrangements are made every year to prevent the pipes from freezing because they were sprayed over preventing the basement heat to keep them from freezing. If these water lines someday need repairs, all the area with sprayed on insulation will have to be removed to fix or modify pipes. Tools that were hanging on the wall was sprayed over and sealed in place. To remove it, the spayed insulation will be damaged. I talked to the Perry Sound office and they sent me to deal with the Peterborough Rep. They said they would come to check the deficiencies. They never came. 4 years later I get angry every time I have to work in my basement. I will never recommend your company to anyone.

I have never had such "good service"!! Matt (sales), then Joel & Adrien, now Ryan(installers)…professional, knowledgeable…even your phone service is great..I spoke to a “live person” (sorry, didn’t ask her name)..who already had Ryan sent. WOW!!

10+ stars, for a 5 star rate… I can not say enough good…It is was so nice to deal with you…I would only refer you, & I do.

Thank you,

The Process was very smooth. The guys showed up right at 7:30, and immediately began checking things out, and getting to work. Matt was great, he was able to fit my schedule for an initial meeting, and provide a clear out line of the work to be done, and the cost of the work. I am very satisfied with my over all experience, and will get GNI back for more work in the future.

I have to say that I am very pleased with all aspects of the job your company performed. From the initial consultation with Pete, who was very helpful in explaining the product as well as supplying the quotation in a detailed and timely manner, to the scheduling and execution of the work. The installers were professional and tidy, and their efforts to keep the adjacent surfaces to their work area protected was greatly appreciated.
This entire project is being videotaped, and I will provide you with the link to the episode in which your company was involved. Thanks to everyone for a job well done.

Mostly my experience was quite good
Bill was very pleasant and informative
Installers were very good and cleaned up after themselves
I only have one concern
I asked them to only lightly spray behind the dryer vent coming down the wall
however the sprayed over it , burying it into the corner and now I cannot attach the other end that goes to the dryer as the wiring is right below there.
I am waiting for my framer to come in to see if he can fix the problem
as I have been away last week he has not been able to get in

Well I guess we booked in late November early December, which is, your busy season..

If we waited until January, we would receive a $50.00 Home depot gift certificate..

No big deal..we waited.

There was an issue when the crew first got here on a Friday afternoon close to 4 pm. " Too much Raccoon feces"

They did not want to do it.

However Matt sorted things out, the crew came back and did a great job..One of the same guys from the first visit was here the second time. Apologized for bailing on us last time, and did a GREAT JOB!!

Kudos to you folks very good price and a very good Job!!!

Recommend you to anyone!!

We were extremely pleased with the professional manner , work ethic of your team.

Jeff explained how we needed to prepare for the installation and how inadequate are current installation was and how much more energy efficient are home would be.

The day of the installation went very smooth , the team were very pleasant , explained how they would access the two attic entrances.

We notice even the following day , how much warmer, comfortable the house was.

We would recommend your services to others.

Looking forward to receiving our reduced heating bill.

Insulation/Racoon attack

Racoons, Trashed my attic..no/minimal.. insulation left, & more. After animal-proofing/caging my house...called Great Northern..help please?. It is cold in here.(happened in the fall).

Matt came & gave me an estimate of cost of damage, Joel & Adrienne came & fixed it. Joel also, checked "absolutely" everything..(I didn't know to check...I appreciate that...I don't know what's up there. Now I do!!)

A great team, these 3 were. I would highly/"only", recommend them.
I was given estimates, from "friends...what they paid"..who had the same issue (not the dealers/fixers). Their (Great North) price range is in the "ball court"..& .. actually, better..they did the job...so cheaper in the long run.

Thank you Matt, Joel & Adrienne.

Both Alana and the installers were great. I did have an issue on the 1st day they were coming out where I was originally booked for 9:30 am but they weren't able to come out till 4pm because of another job. I did state to the guy that called to reschedule for another day that I did needed the room done on the dates promised because of a party I was having on New years eve and the installers were great because the made a point of coming to my house when they were done the 1st job and they stayed late till they were done.

For the most part everything has been going fairly well, with just one issue that was addressed promptly by Richard and Nick to keep things on track.

Richard, Nick, Alana and Linda have all been very professional to deal with and are genuinely concerned about customer service and the quality of the work. As I mentioned, only one issue arose and that was when the installer (Carl) forgot to bring a piece of equipment to spray foam a small section of an exterior 2x4 wall that needed to be done before drywall could be installed. This caused a delay in the drywall installation but when I brought it to Richards attention, he dispatched Nick to the house a few days later to take care of it. Nick also promised to expedite the remaining spray foam and blow in insulation to get us back on track which he has done by scheduling them both in for the end of the month.

So far, so good!
