The overall window replacement was on time and as quoted. We had a bit of a battle replacing two windows for a sliding door. Homeworks said it wouldn't be a problem and they didn't need permits to do this. We checked with the city and were told we needed a permit. Homeworks tried to tell us we had to pay for all the additional paperwork despite the fine print in their contract saying they were responsible for permits. We pushed them and they kept their contract but it was a hassle.
