"Pushy sales. Started off high, reduced the price. Sales guy demanded to leave with a competitors written quote in order to obtain his lower cost ?! I then received a follow up quote regarding a "promotional discount". I said, great please forward me an updated price. I was told this couldn't happen unless the sales guy could come back, clearly it was all BS to simply get me in front of him again for another 2 hours to be pressured into buying. The girl on the phone continuously spoke over me, would not accept the word "NO" to the visit. In the end I had to hang up. This kind of tactic is not good for any customer, it's bullsh*t. So unless you're a fan of what I see as very manipulative behavior and poor sales ethics RUN, do not Walk away...RUN."

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 a FANTASTIC experience with LCT! It started with a prompt response from them, setting up an appointment the next day after a tree fell on my house. James came down and explained everything thoroughly and gave me some options. After talking to a few other vendors, I knew I wanted to go with LCT. Their pricing was better than the other quotes and James was great to work with. Before the crew started any work I met the owner, Luis, and knew I had chosen the right company. He was just as great as James, very thorough and let me know what would be happening. In addition to needing the roof replaced we also had some damage to rafters and decking to replace. After the job was complete, Luis did a thorough inspection of the work and made sure I was happy with everything. The crew did an amazing job and I couldn't be happier with the work. The office staff was also great to work with! I got to meet them when I went down to pay the invoice. A 5 star experience from start to finish. Thank you LCT!"

Ken Cook has been installing residential roofs and ventilation systems for over 35 years. Cook's Roofing is certified by the Certain Teed Corporation to operate as a select shingle roofing company. This allows our company to extend material and labor guarantees for longer periods than the competition. Cook's has two crews and two lead roofers are certified Master Shingle Applicators. Our foreman has been employed by us for over 13 years. According to the building inspector's office, Cook's pulls more permits for roof construction in the town of Bellingham than any other contractor. In 1992 when many of the shingle manufactures were having trouble with their fiberglass shingles, the ASTM (American Society of Testing and Materials) developed testing for shingles that showed many problems with roof shingles. It was right then and there that Ken Cook decided to install the best shingles available and have quality that people could depend on; CertainTeed is the best company for their materials and warranties. They have taught us every aspect of the roofing industry from proper installation techniques to knowledge of how to know the difference between shingles that are of a high product quality and mediocrity. Ken Cook has been a resident of Bellingham for over 50 years. He is an active member of the First Baptist Church of Bellingham serving Christ and the community. He also serves on the finance committee of the same church. Ken is married; they have 2 daughters and 2 grandsons. Ken loves Jesus, (John 5:24) his family and roofing. The entire Cook's family would love to serve you. Additional email - [email protected]. Additional DBA - Cook's Home Improvements Inc. Phone: 508-966-0306 Fax: 508-966-2233

"Very disappointed. We asked for triple pane windows, and someone on their end ordered double pane. Luckily we noticed day of installation, and they had to re-order the proper ones we signed for. Finally the group of installers who came did a horrible job. Trash, insulation, and broken glass on our front lawn. Horribly cut wood trim that we had to redo ourselves. Poor sealing that we need to redo. Our hopper window was misaligned and couldn't close. The hinge arm on our casement window has detached from the channel. Communication is spotty from them, and sometimes we don't get an answer by call or text until we message repeatedly. It took over a year to have our project done from contract signing to end, and there are still issues cropping up. Out of the dozen of contractors we've hired the past year and a half, they have been the most disappointing and for what we paid, the quality of work was truly disappointing."

"We are very pleased with Ray's team work. They did a great job installing the cement board despite the very cold weather (jan-feb). The installation of the door leading to the backyard (garage to backyard) required a bit of tweaking which was done in order to have a good seal. Communication requests by the team to have Indoor access to the room where the bay window was installed could have been better."

Siding questions, answered by experts

A brick exterior for your home has many advantages over other types of siding. While brick siding and veneer are more expensive, they’re also durable, long-lasting, and weather-resistant. Brick siding is aesthetically appealing, and can help to increase the value of your home. It’s also easy to maintain brick siding.

Similar to other types of wood siding consisting of natural materials, cedar siding should last 20 to 40 years. However, the lifespan for any wood siding, including cedar, can be far shorter without the proper repair and maintenance work. Don’t put off making repairs, or problems could worsen quickly. While you can repair minor holes and cracks in the siding shakes, rot and warping requires replacing the boards. 

The living space of a home doesn’t correlate directly with how many square feet of siding you’ll need, but on average, a 2,000-square-foot home will need 1,700 square feet of siding or 17 squares of siding. Your siding measurements will vary depending on the layout of your home, the number of stories, the size of your doors and windows, and even your roof style.

Avoid toxic chemicals that can leach into nearby lawns, as well as household ingredients like vinegar that can ruin paint and sealants. Instead, look for a very light detergent or a dedicated exterior siding cleaner. In a pinch, you can use a basic dish or laundry soap, but we suggest sticking with a dedicated cleaner.

If your siding is struggling with algae or moss, which indicates moisture issues, look for an outdoor cleaner that’s specifically designed to clear moss and algae stains. This is also a sign that you need to seal your clapboard against further problems.

Different types of siding provide unique aesthetic and structural features, with each material commanding its own cost. Availability of materials and shipping costs also factors largely into the cost. The common types of siding materials include:

  • Stucco: $7–$9 per square foot

  • Wood: $1–$15 per square foot

  • Engineered wood: $1–$6 per square foot

  • Aluminum: $3–$6 per square foot

  • Fiber cement: $5–$14 per square foot

  • Brick: $10–$20 per square foot

  • Brick veneer: $3–$10 per square foot

  • Stone: $7–$30 per square foot

  • Stone veneer: $5–$11 per square foot
