Our experience with Millstream was very favorable. We replaced a 23 year old roof that, while not yet failing, was ready for an upgrade. Eric B. was our estimator/sales person - he was knowledgable, personable and provided a competitive quote. I like the fact that Millstream only uses top quality products from Owens-Corning and they are local to the area. I'm a bit of a stickler when it comes to contractual terms, especially with an expense this large, and Eric was patient and accommodating when I requested that additional details on the products needed to be added to the contract prior to signing

Millstream did a great job tearing down and rebuilding our chimney. They worked their schedule around our newborn. Chris even had it sealed it up over last winter, when it was too cold to mix mortar. Thanks guys, we appreciate it.

Millstream did a great job on my roof and I would not hesitate to use them again. The crew showed up on time, completed all work as promised, completed all work as scheduled and did a great job cleaning up afterwards. I will recommend Millstream to family and friends and again will not hesitate to use them again.

Dave at Millstream was a pleasure to work with during the review and quoting process. I tend to want to understand all the details and what I’m getting for the cost and he was very thorough and clear with each response. The overall quote was well within that of other local reputable companies I had quotes with and the quality I received looks to be great as there have been no further water issues that were occurring on the previous roof line. The on-site workers were very considerate and efficient to get the job completed very quickly. The project manager, Anthony, was easy to get a hold of and

Needed a roof to be installed quickly because of leaks. Even with all the rain we had this summer Millstream Construction was able to schedule our roof installation in a timely manner. In a day and a half we had a beautiful new roof. We could not be more satisfied. The roofers did an excellent job and the yard was cleaned of all debris. Everyone at Millstream Construction we communicated with was friendly and courteous. Being personable is why we chose Millstream construction. We would highly recommend Millstream Construction for your next roofing project.

Was doing some construction in one of the bedrooms in my house when I noticed a split tape joint in the ceiling drywall and some water staining. I called Millstream and was greeted very nicely from the receptionist. The technician Craig came by the next day or so and took a look. While he could not find anything immediately, he did instruct that I need to pull down some drywall to get a better look from the inside. One this had been done, I sent pictures of what I had discovered and Craig came back and fixed the issue. He also noticed an unrelated issue with my chimney. Craig and Millstream where

I increased my rating to four stars. Nick Ortiz who is the General Manager at Millstream contacted me after reading my original review from December 2019. He offered to pay for the damages caused to my Gutter Helmet. This was replaced on 1/29/20 at the cost of $300. I am impressed by the customer service to handle this in a timely manner. I will now recommend Millstream to others for roofing projects, but just be aware that they might use subcontractors. I hope the company they use will learn from their past mistakes.

This company did an excellent job on my roof. I bought a special package through Angie's list and paid extra since I needed a rubber roof for a part that was not slanted enough for a regular roof. Even though the estimate I originally got when Millstream came out to give a quote was more than the Angie's List deal (--- and I had forgotten initially that they were coming out because of the Angie's deal), they stuck with the Angie's List package price when I realized that was the source of how I started talking to them. (I was talking with many contractors so didn't mention

Scheduled a 1pm appointment for roof repair with Kevin. He did not show up or call to reschedule. Called Millstream at approx. 3pm and left message inquiring on missed appointment. Did not receive a call back. Surprised as prior rating were 5 stars. Disappointing.

I have had the pleasure of doing business with the Millstream Construction team. Chris Gonsalves, the owner and expert helped me every step of the way. I had a bad roof that was installed by some locals that claimed to be roofers. For the past 2 years it leaked from faulty workmanship and together, we uncovered the many problems, figured what needed to be done (replace the shingles, underlayment, etc..) and a couple months ago, Chris and his team took care of the problems and now, I have a new roof with a "Platinum Warranty".
It really does matter who you hire to work on your house

Chris is a diamond among rough-cut gravel. As soon as we contacted him, he went over and above the call of duty checking on the damage to our house and making sure it was secure as we were 600 miles away. His professionalism is impeccable. Good communication and can-do attitude. His team was professional as well and hard-working.

I had roof damage after a major wind storm in March of 2018. This caused water to leak into my attic and down into the second floor of my Multi-Family.

Originally the insurance company claimed that only half of the roof needed to be replaced, but Chris identified and explained why the damage had been more severe than originally thought. That kind of attention to detail and consultative service is what drew me to work with Millstream and Chris in the first place.

In very short order, he had a team at the house and in a single day had completed work. It was so well done that I used them to install

Not only is Chris personable and professional, but his crew came out and did my entire roof in a day and it's an extremely large roof :-) and they're clean up was awesome. They even moved my potted plants away and back in place before they left. Additionally, because of his status with Owens Corning I was able to get the full 50 years warranty for workmanship and labor.

Millstream Construction owned by Chris Gonsalves is an amazing, professional organization. We hired Chris recently to conduct a roof inspection of a home we were buying in the Hartford area. He was awesome! He arrived early and got down to business, inspecting the roof as well as all of the flashings, skylights, and chimneys in the home. He climbed out on the roof as well as using a drone to conduct a full, thorough inspection. He made a ton of pictures and told us exactly what he thought and which he thought should be the priorities. I have NO DOUBT that when it comes time for us to repair

Honestly, I was blown away. Damien showed up and was able to make a repair right on the stop. I wasn't expected the quick turn around, professional attitude, and positivity. I am grateful we connected to them!
Any future home repairs are going through Millstream. Couldn't be any more impressed.
