Your Home. Your Priorities. Our Expertise. For more than half a century, GF Sprague has been a growing part of Boston’s architectural fabric. We began by restoring slate roofs and hand-forming copper details for some of the area’s most historic sites and city buildings. These weren’t just jobs, they were lessons in precision and pride. Slate and copper demanded true craftsmanship, the kind that can’t be rushed or faked. That craftsmanship is our foundation. As Boston grew we did too, expanding to help homeowners in the surrounding towns. We wanted to bring the same standard of excellence required on those historic projects to everyone. Today, GF Sprague adds on to our traditional roofing specialties with asphalt, rubber, and cedar. -In addition to our copperwork we can also work on chimneys, gutters, windows, and siding, Whether it’s a 100-year-old brownstone or an updated colonial home, we bring the same commitment to detail, durability, and integrity that defined us on day one. What truly sets GF Sprague apart isn’t just our skill, it’s our promise to treat every customer like family. Every roof we install is a promise: to protect a family and carry forward Boston’s tradition of homes built to last. Along with that promise is another, our Best Price Promise. This means you get the best price for your project every time. Many of our clients have trusted us for generations, passing down their loyalty just as we’ve passed down our craft. With GF Sprague, you don’t just get a contractor — you gain a lifelong, local partner in caring for your home’s exterior.

"Very impressed with Sprague, Mark was very knowledgeable and straightforward. Crew was first class closing roofing and Clean Up in four days and cold weather. Justin was terrific, personable and responsive, and was always on site or available. Crew and especially Foreman were excellent. I would recommend GF Sprague for a high quality Job, their technology and customer service."

"I had leaky roof. Of 3 contractors who came to take a look, only Ramon from NMTI pointed out an uneven surface that seemed to be good place to look for an issue. I appreciate hearing specific ideas when there’s a problem, so we chose to work with NMTI. Sure enough, underneath the shingles on that section of roof, there was some water damaged and warped plywood. The NMTI team addressed that and re-flashed some skylights at the same time. The team was all very pleasant. They scheduled the job quickly, once we agreed on details and I would work with them again. Thanks, guys!"

Formerly known as Beantown Home Improvements. 3rd Generation family owned and operated. We specialize in Asphalt Roofing, Rubber Roofing, Skylights, Vinyl, James Hardie Fiber Cement, Cedar Siding, Decks, Windows and Doors. In today's day and age where quality, craftsmanship and simple honesty can be tough, if not impossible to find, you need not look any further. We do it right the first time. When it comes down to it, we’re not sales people and no one likes to be sold. Our goal as home improvement experts is to inform you of the products we offer and how we can be of service, so that you can make an educated decision that you can live with and we can stand behind. With our simple no BS approach, our objective is to be up front and honest with every client, earn your respect, and offer outstanding customer service that is second to no one and Jim guarantees that! We are fully licensed (CS-107322) & Home Improvement Contractors (178728) and carry $1M-$2M in liability insurance.

"We started out dealing with one of the sales reps John Fossetti. Great experience. He told us about the company, about the products, had samples and a huge selection of siding to choose from. He was very open and answered all of our questions. After several consultations with many companies we knew Beantown was for us. We scheduled siding replacement for our entire house as well as new window replacement for all windows - 24 of them and a new slider. They were very professional and their crew was excellent. The windows had all new construction around them and we got ProVia windows that carry a lifetime warranty. They removed all of the old siding, fixed any rotten or damaged areas, wrapped the entire house to waterproof it and hung new siding, trim, gutters and gutter guards. It turned out absolutely beautiful. Our house looks new again! Jim Ewell the project manager was great to work with. He was very supportive, professional and answered all of our questions. Both he and John were a pleasure to work with. Also, their office staff were very helpful as well. Beantown went above and beyond for us and were so reasonably priced. I highly recommend them! I would definitely use them again for any future projects!"
