Great Northern Insulation

For our basement, we did R20 on the foundation walls and R24 in the Rim Joists. We excluded the mechanical/furnace room as we did not want to incur additional costs [from our general contractor- GC] for the existing batt insulation removal, framing, and then drywalling over the spray foam since you can not leave the spray foam exposed. It should be noted that GNI can remove existing insulation for you, but it will likely cost you more to use them for removal since their labour rate is likely higher than a regular GC.

Our basement is about 950 sq ft in area, but the quote was based on linear feet (as were all our quotes for Spray foam). Hopefully providing you the sq footage will give you an idea of your expected costs.

We selected the closed cell BASF (purple) Walltite Eco Polyurethane Spray foam.

Alana C. was easy to deal with. She is the one the came on-site to do the quote. We had her come back an extra time after our general contractor completed the framing/electrical/plumbing as we had some concerns that there may be some areas that would not be accessible to GNI.

We dealt with Nick in the back-office for scheduling the work appointment (1-day of work) and payment including 20% deposit.
For the deposit, you also need to pay the HST on the 20% deposit at the time. The $3,395 costs noted is before HST.

Both Alana/Nick were reasonable in answering questions. The one thing I didn't like is that I had emailed both at the same time asking about energy rebates available for us in the area. One replied saying there was none and another replied saying that there were rebates available. So it was confusing to get contrasting responses.

The actual work was done reasonably well. My GC who does a lot of basements and has seen other spray foam Companies as well has no concerns with the quality of the work. Two younger guys came to do the spraying work.

They did leave a bit of a mess. For example,
1) bits of broken off spray foam on the main floor inside the house even though they were only working in the basement;
2) a few spray foam pieces that I had to clean up from the front yard;
3) a couple of good-sized rocks left in the basement. No idea where the rocks came from but perhaps they use the rocks to keep some protective equipment in place. I had to throw these rocks out on garbage day;
4) the left the mesh screen off when the closed the basement window. The popped it off to bring equipment into the basement but never put the screen mesh back when they were done.

Overall, I'm still happy with the work done.
