    Lisa L. of Danbury, CT

    Customer Testimonial

              This contractor was professional, thorough, knowledgeable, organized, and pleasant. He met with me to understand what work needed to be done and looked over the site. He provided an estimate and after the contract was signed and down payment made, he followed through on everything agreed to. He gave us a fair price and there were no surprises, we paid what was agreed upon. The work was completed efficiently, the workers arrived on time, when they said they would, and then followed up after the job was completed. I recommended them to my neighbor, who also used their services. I would definitely use them again!

    Customer Testimonial

              They knew what they were doing and the materials seem to be of high quality. But it has only been 3 months. I do not think I will have any problems and that they will address problems as they arise.

    Customer Testimonial

              Ripped up my damaged roof, repaired plywood, re shingled large area and matched to old shingles. FANTASTIC!!! I normally don't fill out these reviews but i felt it's important to spread the word about Millstream Construction and there awesome workers, Especially the foreman DAMIAN and his fast clean crew. "You want these guys working on your house" They arrived on time at 7AM Fast, & clean there done & gone at 11:30 AM not one scrap or nail or any garbage left at all. PLUS Damian removed 3 old satellite dishes from my garage roof at no extra charge..I tried to give him a tip but refused to take my money. In this world of ripoff & scammers it's sure nice to get such a perfect service.. Thank You Guy's!! Paul J. D'Ambrose

    Customer Testimonial

              Millstream Construction was contracted to replace my roof. This company deserves nothing but praise. The owner Chris, contacted and kept me informed about my project, he was polite, professional and above all listen to my concerns and reassured me that the job would be completed as promised. He also followed up when the job was completed to see if I was satisfied. The crew arrived bright and early, got right to work. They were quick, neat, professional, polite and very very good at what they do. My roof came out awesome. Chris should be proud to have these men working for him. His job supervisor, Steve, did not just sit around. He worked just as hard. Steve and the other guys (don't know their names) worked hard and were done in several hours. They then cleaned my roof, washed my house, raked my lawn, swept my driveway. My property was immaculate when they left. I am a disabled police officer. This company I will highly recommend to anyone. Great company!

    Customer Testimonial

              Millstream Construction was very honest, up front, and timely. They kept me informed of any progress and of how things were going. They made sure I had a chance to go out and inspect the roof itself. Communication and timeliness were big positives for them. I would like to recognize the owner (Chistopher Gonsalves) and his project manager (Craig Kelso) for their exceptional service. I would definitely recommend Millstream Construction and I would use them again.
