What Do Customers Say About the Millstream Construction?

yelp.com

Positive reviews:

“I had roof damage after a major wind storm. Originally the insurance company claimed only half the roof needed replacing, but Chris identified and explained why the damage was more severe. That attention to detail is what drew me to work with Millstream. In a single day his team completed the work, which was so well done that I also used them to install gutters. I wholeheartedly recommend this company if you need someone reliable and trustworthy.” – Andrew L. ⭐⭐⭐⭐⭐ August 11, 2018

“Chris is personable and professional. His crew did my entire — extremely large — roof in a single day, and their cleanup was awesome. They even moved my potted plants out of the way and back before they left. Because of his status with Owens Corning I was also able to get the full 50-year warranty for workmanship and labor.” – Marion B. ⭐⭐⭐⭐⭐ June 8, 2018

Negative reviews:

“They replaced my roof, took my gutter guards, and left without telling me. In the fall I noticed leaves in my gutters — the guards were gone. Millstream came and put up mesh guards, then charged me $500 for a full box of guards for the garage. The tech told me he ran out of pieces mid-job. I asked the office why I was charged for a full box when only 13 pieces were used — they had no answer. Also, roofers are supposed to leave remaining shingles with the homeowner; Millstream did not do that either. Will never recommend this company.” – Stella J. ⭐☆☆☆☆ November 8, 2024

“Most awful company. They installed a new flat roof that has been leaking consistently since completion. They failed to properly supervise employees and refuse to make repairs, blaming everyone but themselves. The aesthetics of the job were terrible. Stay away.” – Larry K. ⭐☆☆☆☆ September 24, 2021

Positive reviews:

“We needed to find and fix a troublesome leak on our investment property. Millstream worked us into their schedule promptly and the service was both professional and efficient. We couldn’t be happier and give them our highest recommendation.” – Carolyn G. ⭐⭐⭐⭐⭐ October 9, 2024

“Friday and they came out first thing Saturday to do triage on the roof to address the 5 holes in the roof. That Saturday morning it was minus 10 degrees. They also gave us help in choosing the shingle we wanted. Millstream stripped the roof, replaced plywood and flashing before putting down the new roof. The crew and supervisors were hard working and courteous. We would highly recommend Millstream.” – Barry B ⭐⭐⭐⭐⭐ November 15, 2023

Positive reviews:

“Millstream construction is A+ company they came all the way to where our location which is southeast and the references which I reach out to were all A+ Better Business Bureau was all A+ so I was very happy with them” – Wilmer L. ⭐⭐⭐⭐⭐ July 2020

“Millstream and Craig were incredible — responsive and honest. They came on a rushed basis after potential damage to our roof by an antenna installation, inspected it, made some small adjustments, and confirmed all was fine without charging us. This sort of customer service is rare and I look forward to using them in the future.” – Jeffrey G. ⭐⭐⭐⭐⭐ November 2019

Will never recommend this company.” – Stella J. ⭐☆☆☆☆ November 8, 2024

“The deal was for inspection and repair. The person came and inspected but found some roof gutters were not attached to the roof — and did not repair the minor works.” – Tushar A. ⭐⭐☆☆☆ October 2017

Positive reviews:

“Excellent job — very thorough, conscientious workers with great work ethic. The team works together well like a well-oiled machine. Each person knows their role and what needs to get done. Would not hesitate to hire them again.” – Sandy S. ⭐⭐⭐⭐⭐ 2023

“Juston is a great credit to Millstream and very efficient. The crew worked well with him and did an excellent cleanup.” – Lewis S. ⭐⭐⭐⭐⭐ 2023

Negative reviews:

“A salesman posing as the owner convinced me to pay $1,300 for attic baffles and basement sealing in exchange for a $500 discount on the roof. Neither the baffles nor the basement sealing were ever done. I later discovered the check had been made out to his personal name, not Millstream. After a year of legal attempts, he has failed to appear in court repeatedly and has not repaid a cent. When I contacted Millstream, they refused to help — despite the fact that this employee had previously been arrested for stealing from at least two other customers before they hired him. Find someone else.” – Kevin D. ⭐☆☆☆☆ 2024

Google Reviews

Positive reviews:

“I needed my leaking skylight replaced in a hurry and Millstream was the most responsive company, came in with the most competitive quote, and had the quickest install schedule. They even managed to get the finish carpenter out the same day as installation. Other companies were going to charge extra for finish work or wouldn’t do it at all. Millstream also had the best warranty and mailed me a hard copy of the warranty certificate afterward. So glad I chose them.” – Kristin Black ⭐⭐⭐⭐⭐ September 2025

“Having work done at our home over the years, Andrew — the manager for removal and installation of our new roof — made our contracting experience a dream. The crew was very professional and proficient from start to finish. Thank you for the wonderful work.” – James Tvrdik ⭐⭐⭐⭐⭐ 2024

Negative reviews:

“They cut corners, use improperly trained subs, have safety issues, and don’t pay subcontractors — then cycle in new ones who don’t know this. Sales people have no idea about roofing and what they are selling. Please do your research before using this company or you could find yourself with mechanic liens on your home.” – Darren DeBerry ⭐☆☆☆☆ 2025

“It took days for them to call me back about a serious roof leak. When they finally called, it was near the end of the day and I missed the call. I called back 5 minutes later and no one answered. When someone did answer, they made an appointment. The next day the original employee tried to change it. There was no concern for my problem or my schedule.” – Les Fisher ⭐☆☆☆☆ 2023
