"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"Planning: We met with three contractors and reviewed small, medium and larger options for our existing space. Ryan from Norman Builders won us over with his confidence, organization and no problem attitude. Of course we had concerns and questions, but it was clear he had worked in colonial houses before. What really won us over was his excitement to do something different with our space. From day one, you could tell every detail of this job mattered as this was a new way to design a traditional space. His timelines, pricing and execution plan was clearly laid out. As a GC, he organized everyone from; designer, permits, dumpsters, demo, electric, plumbing, painters, floors, ceilings, etc. He would do it all. The Job: Completely gut our existing kitchen and formal dining room. Remove a wall and install a steal support beam. He'd then move the kitchen to the old dining space and make the old kitchen a common area with built in desk, bench and bar area. The dining room would then be moved to our four season bonus room. Floors, wall, ceilings all came down. All new plumbing and lighting throughout the first floor. Execution: I mean, its funny to say, but we miss these guys. They practically lived with us for the summer. Couldn’t have been better with our entire family (kids and dog included) Everyone was so respectful of world climate (summer of Corona) and space. Of course you need patience with the process. Timelines were clear and the job finished slightly ahead of schedule. In the End: I mean, wow. When we looked at the blueprint on day one, we legit thought they shared the wrong plans. We couldn’t imagine everything we wanted would fit. They nailed it. It’s a dream space for our family and we couldn’t be happier. We couldn’t recommend Ryan Norman Builders any higher. We can’t wait to have them back to work on the upstairs next."

"Paul and Jay were a pleasure to work with. We added on a 10x14 addition (dining room) to the house. They were extremely flexible as the design location and final specifications changed several times. The price was very fair and allowed for 2-3 progress payments along the way. Jay's attention to detail in putting the hard wood floor down was amazing as he matched panel to panel from the connecting room. They brought in their contractors for HVAC and electrical ( pricey there ) but that helped us a lot! Highly recommended.. Thanks again Paul"

"I am extremely happy with the painting and carpentry work done by D&S. The workers came every day and worked long hours to get the job done. Not only did they do a great job but they were pleasant and courteous as well. I would not hesitate to hire them to do additional work for me and I have already referred D&S to others."

"We worked primarily with James to have a skylight installed in our recently constructed bathroom, as well as replacing an existing window in a bedroom, and adding a storm door. He was prompt and communicative, and very diligent about ensuring the space was clean and tidy after the work was completed. We are very happy with the installation of the windows and storm door and would recommend!"

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

"Went well.  The torrential rains the following week revealed that the upper end of driveway near garage needed to put built up a bit more to keep the rain from puddling.   The guys came back a week later, after the rain stopped and build up the driveway.   They burnt the tar to blend it into the existing driveway.  
The driveway is a difficult one to do.   There is absolutely no grade to work with - it all had to be built up.  
TMC was the only company who said they could do the driveway with out a drainage system.   All the other contractors would not consider it.    We did not want the drainage system because it does not work.  We are all ledge and granite underneath.
Looks beautiful!!!   Will definitely have them back to do other work."

FAQs for addition to existing structure building service projects in Lowell, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
