Our Clients Say

“The biggest challenge for a contractor is to find a group of sub-contractors that can work together as a team with the goal of turning out a quality product at an honest price, and at the same time have a stress-free job site. ISM can do just that. They always showed up with a smile and went above and beyond. So very glad to have Shin and the ISM team on board.”

Maurice Barnett

“Shin and his crew have been one of the most professional teams we have worked with in our 15 years of doing business. They work quickly, cleanly, and efficiently. The ISM team is competent and have fixed every problem we have had the first time with no hassles. He has worked on our commercial properties, our restaurants, and our home. We would trust him with any project, no matter how big or small!”

Michelle & Steve, owners of 555 and Petite Jacqueline

“As contractors building new and remodeling older homes we have worked with Integrated Systems of Maine for more than 10 years for all our plumbing needs. Shin and his crew are responsive and thorough. They take time to explain the process and offer suggestions for heating, cooling, and fixtures. Shin takes pride in his work and wants his customers to be 100% satisfied.”

John Caprio, JCap Properties Inc.

“The folks at ISM are life savers! On more than one occasion, they’ve fixed my heat, hot water or leaky pipes before damage was done to my properties. As a landlord and single-family homeowner, I highly recommend ISM and will continue to hire them for all my relevant needs.”
