The only reason that this review doesn’t get a zero or 1 star is that I will give Great Northern customer service some credit for trying to make our spray foam insulation job at our cottage right.
The spray foam work done deserves a zero or no stars. Our old cottage had exposed 2 by 4 walls and there was not a single cavity that the foam did not protrude beyond the studs, making installation of any wallboard impossible. On top of this despite stapling up plastic barrier (we know because we had to pull out hundreds of staples, some on unfinished parts of the cottage but also some in our floors, the wall quarter-rounds and even in some of the finished wood areas or the cottage) there was overspray everywhere, most significantly on our ceiling where we intended to leave natural wood with a whitewash finish. So GNI tried to make it right. They sent crews for 2 more days meaning we were displaced from our place and it required vacation days to be there. After two days of working with 2 people on the first day and 4 people on the second day with work involving what they call scarfing (sawing) the walls to remove excess foam and scraping the ceiling and then sanding the ceiling I asked the site foreman on day 2 if there were vacuuming the walls. He insisted that the crew would sweep and vacuum the walls. The did run one vacuum (they could have used three) and then wrapped up the job. Going back into our place and starting to put furniture back in place we realized there was bits of purple foam dust everywhere. My wife and I vacuumed with two vacuums for 2 hours on Saturday and another 2 hours on Sunday. Upon more correspondence GNI offered to come back to do more cleanup but I declined. At this point I no longer wish to be displaced from my place nor do I trust their quality of work. As I said to them, when a job is done this poorly it is almost impossible to make it right. My wife and I plan to do a complete wall vacuum with a brush attachment to try to remove as much of the loose foam as possible on our next trip to the cottage. Hopefully this will somewhat remedy the situation until we can drywall.
Did GNI attempt to provide good customer service? Yes. Did they do the job with any sort of quality? No. Would I recommend them? I leave that to your judgement.
