    Chris did a great job of describing the work his team were going to do on my roof! Everything was done just as described and the roof looks great! They did an excellent job cleaning up after the whole roof was removed and replaced too.

    The purpose of this review in an unsolicited testimonial on behalf of and for Chris Gonsalves, owner of Millstream Construction. We known Chris for a number of years and in that time he has been found to be not only a trusted confidant for business concerns but a friend as well. His staff is highly proficient as well. His judgment for work to be performed and the corresponding estimate of costs are always fair and equitable according to industry standards. The actual workmanship is excellent and he employs a respected business model. The above represents a sincere and honest feeling on our part based upon actual experience and in no way whatsoever should be mistaken as being patronizing as sometimes happens in these cases.

    Customer Review

    By Bret C.
    West Granby, CT

    I met with Millstream from a recommendation of a friend. I had experienced severe storm damage from hail and interviewed 4 roofing companies. Chris represented his company well by being attentive, professional and offering answers that completely satisfied my inquiries. He also went above and beyond by engaging with my insurance company who valued the work much less than the actual costs. Millstream's quote was similar to all the others I met with but the difference was that Millstream engaged with me as if I was their only and best customer. I am very happy with the results of their work and would highly recommend their services.

    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!
