5.0 Andrew S. Londonderry, NH

Had house and garage roofed and repaired. Always on time or earlier. Hard workers. Excellent value for the money. Would highly recommend!

5.0 Vic D. Concord, NH

First of all, Maria in the office was amazing in communicating when Manny and his crew would be there. Maria and Manny both responded the same day often in hours about any questions we had. We called originally for water damage we felt was cause by a bad door install. Manny took a look and showed us that the damage was worse than we thought. The water damage was coming from above. Our whole side of our house was damaged by wind and water. Manny wrote me the estimate on the spot and when i asked how soon he could start he said now. Manny and his crew finished the entire job in 2 days. They worked from 8am til 7 each day, and they replaced our door correctly. All the sheathing and vinyl siding had to be replaced on the north side of the house. Manny found the exact match of color for the vinyl. In addition when Manny was up above he noticed the caps on our roof were in bad shape and tiles on our roof had worn down at the peak. Again we asked Manny for an estiimate and then we agreed to let him to take care of it. Manny and his crew can back and finished in 1 day:). None of this was upselling by Manny. It was obvious there was extensive damage and it needed to be fixed immediately. Manny did not pressure us , he just showed us what was going on. After a week we decided we wanted a change to the bottom of our door and Manny came out and changed it in a few hours. We ended up getting thousands of dollars of work done for a price that was more than reasonable. The quality of work that was done, the communication and professsionalism was unmatched in my experince with an contractor or repair business we have dealt with. If I could give them 7 stars i would. My wife and I were extremely happy. Price, workmanship, speed of work, dependability all top notch. In additon their consultant Ed was fantastic. He came to our house and gave us the initial estimate for our water damage (that ended up being more severe) and told us who Allstate Quality Construction was and that they are a family business wtith over 23 years experience. It was a bad situation for us that turned our very good. Thank you so much Manny, Maria and the rest of your family. I will recommend your company any chance i can!

5.0 Michael S. Richmond, VT

Manny and his crew replaced my ridge cap and installed a ridge vent. The weather prediction was completely wrong and the rain started after they had torn off the old cap. They worked in the rain to finish the job and close everything up. Good work and great service. I would hire them again.
