"I bought an older home and needed some gutters replaced and repaired. Since we had recently spent a lot of money renovating home, I was budget conscious and did not want to spend a lot of money. We har All State and several vendors give us quotes. All State was a smaller family run business that was prompt and gave us a great price. We only started with a small job but ended up doing a full gutter replacement and added gutter guards. The price was fair and they completed in one day. Very happy with the work and service. Would highly recommend. And I am a builder so take a lot to get me praise. Happy customer in Darien, CT"

"Henry and his team were profession and hard working. Here on time and started the job when they said they would. My roof was seriously damaged after the Aug 4, 2020 storm dropped a 60 foot tree on my house! Once they opened the roof, the work doubled as the team worked 11 hour days to replace 2 cracked support beams, 50+ splintered rafters and 20+ pieces of plywood before they could even start to install new shingles. In spite of the damage, that was much worse than anyone expected, Henry handled everything like a true pro. He assessed what needed to be done and got the supplies he needed delivered that day. His team worked incredibly hard. I was provided with pictures to support my insurance claim. Connecticut Masonry & Waterproofing, LLC took care of it all - the main roof, the garage roof, the roof repair, the chimney repair, the gutters and downspouts, even the damaged siding. The clean up was done so meticulously, at the end of the project, my property was 100% cleared of any debris, remnants and stray nails. Their work ethic and superior workmanship make this company the ONLY choice for all your house repairs. Henry and Xavier(Juan) get the job done! (And they are really nice guys.)"

"They came out the same day I called and had an estimate to me the next day. I asked them to estimate some other work and in the end we hired them to fix our rear gutters, install gutter guards and repair our chimney. We plan to hire them for some other projects."

"I had a great experience from initial phone call inquiring about gutter repairs and roof repairs on my home. After contacting a few companies for estimates. I decided the customer care, warranty, and pricing was best with Home Genius. I had my roof and gutters replaced with gutter guards, the crew was efficient, neat, but most importantly everything looks great! Thank you to Alex, Andrew, Becca, and Taylor they were all knowledgeable and answered my random questions almost immediately."

"I had a great experience with Fairfield Gutter and Exteriors! From start to finish, they were professional, efficient, and very thorough. They came out to assess what needed to be done and took pictures so they could clearly explain everything that needed attention. They walked me through the entire process and explained in detail what needed to be done, which I really appreciated. Once they started the repair, they completed everything in just about two and a half hours! The work was done efficiently and professionally, and they did a great job. I was also very impressed with how affordable the service was. I highly recommend Fairfield Gutter and Exteriors to anyone looking for reliable, professional, efficient, and reasonably priced gutter or roofing repair services. Excellent service from beginning to end! Maria R."
