What We Do

Located in Westbrook, Maine, ISM offers a wide range of services for both commercial and residential clients, from plumbing and heating to energy management and kitchen design. Founded in 2010 by Shin Sargent, ISM started with a simple idea: to provide sterling customer service and an expert eye for detail at fair, competitive prices. By using the latest products and technologies, ISM is able to provide the highest level of technical support.

From the first estimate to the last tightened bolt, ISM aims for true transparency, professionalism and dependability, whether you’re a first-time customer or seasoned contractor. It’s a big reason why a bulk of their business comes from word of mouth. Day or night, and no matter what the job, their staff is on call to make sure everything is working as effectively and efficiently as possible.

ISM’s goal is to treat your home or business like their own: with care and respect. It’s no different with the company’s employees, each of whom receives a comprehensive benefits package, including health insurance and an IRA account, as well as paid holidays and opportunities for advanced certification.

ISM serves the greater Westbrook, Gorham, and Scarborough, Maine areas.

SHINOwner & Operator
In 2010, after working for several local plumbing and heating companies, Shin Sargent decided to strike out on his own. His vision: to create something above and beyond the typical HVAC company. In ISM, he’s built a business where bolt-tight service and customer satisfaction go hand in hand.

JESSICAOffice Administrator
Bringing a deep background in customer service, Jessica joined the ISM team in 2015 as an office administrator. Today, she handles everything from finances and team-management to overseeing customer relationships. As ISM continues to grow, she hopes to further position the company as a role model within the Westbrook-Gorham community.
MATT J.Technician
Matt joined the ISM team in 2017, bringing with him years of HVAC experience—not to mention a happy-go-lucky attitude that always seems to lighten the mood. Together with his wife and two daughters, Matt lives on a small hobby farm in Saco, where he enjoys the simple thrills of fixing up an old property.
WILL B. HVAC Specialist
Upon returning from a two-month trip to Europe immediately after college, Will entered the HVAC field with what he admits was “absolutely zero experience.” Today, the 35-year-old Bridgton resident says his goal is to learn something new every day. All while bringing an efficient, detail-oriented approach to the craft.
DYLAN L.Technician
He may be one of the newest member of the team, but Dylan can install mini splits with the best of them. Always eager to jump in, Dylan has brought an infectious spirit to ISM since joining in 2017. Today, Dylan has become a staple of the company’s growing rough-in plumbing operation.
Scott M.
Scott M.Master Plumber
Scott has plumbing in his blood. His uncle and grandfather were master plumbers, and growing up next door to them in Massachusetts, he inherited their work ethic, wisdom and their trade, becoming a master plumber himself. Scott lives in Scarborough where he enjoys an outdoors lifestyle with his two kids.

Our Clients Say

“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.”

Leila Z

“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 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!”
