"I was happy with the work done by Matt and his crew on my roof replacement. Of the highlights, Matt excelled at customer service. I had spoken to several contractors during the bidding process and Matt clearly stood out as someone to provide detailed guidance and credible advice on the project. As my roof was being replaced as part of an insurance claim, Matt took the initiative to bring in additional contractors to build out an initial estimate for all of the work, to get things moving with the insurance company, which was a huge help. Matt took things a bit further and spoke directly with the insurance company regarding details of my roof and other work that was not started yet and was able to help me gain significantly more coverage than originally provided! Matt was always available for questions and promptly returned my calls and emails throughout the process. In one instance, I had requested that they hold off on installation of the ice and water shield one day due to the cold temperatures. Matt agreed to this with no hesitation, even though it required them to work the weekend to complete the work. Per my inspection throughout the roofing process and after, everything looked good and I found only a few things that were missed, which Matt took care of immediately. Some mess and nails were left behind after the work, but it was fairly minimal. Due to the scale of the work, Matt / MMP did bring in subcontractors to perform much of the standard roofing work. I would have appreciated if MMP was more forthcoming about this earlier in the process. MMP had someone from their team on-site for the entire process, but I think that they could have kept a closer eye on the sub-contractors work. For the more challenging tasks, Matt came out and did the work himself. He and his team worked hard throughout the process, working long hours and through the weekend to get everything completed in a timely manner and reduce risk of water leakage in case of rain. I will certainly consider MMP for future work on my house."

"Scott and crew did an amazing job. We wanted to make our porch into a windowed room and wanted to heat it using a gas stove. There were many challenges but they were to able to address them all up front and actually came in slightly under budget. They made me aware of all of the options detailing pros and cons of each. All of his crew was punctual, professional and easy to be around. The sub contractors were also top notch. I would definitely recommend them."

"Bob was responsive within a week to come out and scope the work. I went with Bob because he was very through when he came to look at the work and explained the options/ different aspects that could impact the cost/work. Based upon that alone, I hired him as most other contractors came out and looked for 5 mins. He was on target with his projected start date and moved very quickly. Him and his team took care with the rest of the house when it came to protecting the flooring/ keeping the dust from spreading. He works with Nashua Tile & Flooring, Brain there was awesome at helping and explaining options. Overall Bob takes pride in the work and ensuring the customer likes the product. I would hire him/ team again."

"(1) CP Construction and Carpentry did a fantastic job of leveling my deck for a reasonable price and completed the job in just one day. The deck was sagging from the Ice/snow storm back in 2015 from too much snow sitting on it. I would definitely hire them again."

"Stephen helped us renovate our condo in Boston in 2021. The work included complete bathroom renovation, electrical work, and building new closets. He found great contractors who did an amazing job, he also took care of all the paperwork/permits/building management, and helped to select and buy all the materials and appliances. He is proactive, professional and helpful, and I'd certainly recommend working with him."

Unfinished Carpentry FAQs, answered by experts

Bump-out additions can extend anywhere from 2 to 15 feet from an existing room. The right size will depend on how you plan to use the new space. For a cantilever bump-out, which doesn't require additional foundation support, the limit is typically 24 inches (2 feet). If a footing and foundation are part of the project, a bump-out can be much larger, even encompassing a whole room. It's also important to remember that many residential properties have limits on the total house size relative to the lot size.

Carpenters are trained to take on a wide range of home projects. You can hire a carpenter to do framing, roofing, build custom furniture, and make significant upgrades to your home. General carpenters are usually able to handle most jobs. However, you may also choose to hire a carpenter who specializes in a specific type of carpentry. 

The best way to calculate framing costs is by basing your costs on the square footage of your home. On average, framing your home could cost anywhere between $7 and $16 per square foot. 

To ensure you don’t go over budget, base your estimates on the higher end of the price range. If you know you’re going to use high-end materials or require a custom or complex build, you might even want to tack on an additional 5% of your budget.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.

While it is possible to build a wooden carport yourself, especially if you are skilled in carpentry, professional construction is recommended. Professionals ensure structural integrity, proper anchoring, correct alignment, and the use of quality materials for a stable and durable result.
