NES Spray Foam Insulation

This company appeared to be reputable but overall we had a terrible experience.
Scheduling and communicating with them was very tough. It took a very long time to be scheduled and when they weren’t finished with the job on the first day they didn’t come back the next day like you would expect. The whole process took a couple weeks.
Not only did they NOT inform me that I need a special permit for this type of insulation in my attic (granted maybe I should have known that) but they also did not provide the right amount of foam (R-​value) for our project. I only found this out after going back to city to apply for the permit after the work was done. Now we have to go back and add additional foam to meet city codes.
The work they did was also very sloppy. Other contractors have even asked us if we did it ourselves because of how it looks. There is spray foam everywhere! It is all over the floors and even on the wood beams I asked them to keep neat because we were going to leave them exposed. They even used spray foam over some knob and tube wiring we had up in the attic. Our electrician informed us that they should known not to use spray foam over those types of wires. Now, we have to go back and carve out the spray foam to get to the wires.
I really hope other people have a better experience with this company but our experience was not good.
