I am very pleased with the work to spray foam the walls and ceiling of my new 36'x76' Porsche shop, and then also with the additional work they performed of painting the foam. The price was very competitive, but the important thing is Ron listened to my needs of AC'ing the shop and designed the wall and ceiling thickness for the best outcome for efficiency. I then asked about painting it, and he gave a very competitive price. All of the work was done in the exact time frame that he stated. The workers were diligent and proficient. The shop was just as clean when they left as it was when they arrived. Zero trash residue. I would certainly use them again if the need would arrive. I had several bids. I had gotten several bids. I went with J-N-J because after speaking with Ron, I felt very confident. He came out to inspect the building, which other companies did not do...they just gave a bid based on the shop dimensions. Once he looked at it and we discussed my needs, he gave an even lower bid as he assessed what my needs were. I initially was just looking for the lowest bid. but, after thinking of what I needed because I was going to A/C the shop, I just wanted the job done that would give me the best energy efficiency. He discussed it with my A/C contractor and went the mile to give me what I really needed. Totally pleased read more
