"Eric's team rebuilt our entire three season room, which was not functional. It is now, thanks to Mike and Brian. It also looks very good! Mike works hard at getting things done, and teaches the younger crew very well. He is structured and trustworthy. He also was patient answering my questions (I always have too many..!). Brian pays great attention to detail! I was impressed by how good the tile work looks, and also how good the finishing of the decking to the landing looks like, which he did. They also had to partly redo the patio, and it looks better than before."

"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"The workers came on the appointed day with a longer ladder, as suggested.    Terry called to ask if he and an assistant could come by earlier than the original appointment time because they had finished work scheduled in the area earlier than expected; that certainly worked for me.    He surveyed the roof, took pictures and reattached a loose shingle that had fallen into the gutter.   Terry showed me the pictures of the roof from many angles; they showed no other repairs were necessary at this time.  Terry asked if there was anything else that required attention, but nothing else was immediately apparent.  He gave me his card and explained that the company does general contacting work.  
I am very impressed with the speed and efficiency shown today and won't hesitate to call MMP Construction in future if I need general contracting work done.

"We hired Joe and his team to build a deck on the back of our home and gut renovate our kitchen. The final products look amazing and we’re very happy with the new spaces. Joe and his team did high quality work and were very friendly. These were our first Home renovation projects and we plan to hire Joe again in the future."

"DiOrio builders did excellent basement work. Before DiOrio- my basement unusable, a dusty mess, the walls and ceiling peeling so bad, I couldn’t even walk in there without being covered in chalk. Quotes from other contractors were outrageously high, with a bunch of complicated add-ons. DiOrio builders found a solution at a price that made sense, they fixed exactly what needed fixing. They demolished the old structures, scraped the walls and ceiling, removed decades-old debris, sealed the foundation and put a bright white coating on the wall. Plus, once they removed all the debris, the air quality is much better in the upstairs of my house! I’m so happy they made my basement useable, and I will definitely be calling DiOrio Builders and Designers when it’s time to build a lounge down there."

"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."

"Any construction can be stressful, but with Liam and his team I was in good hands. I had some upgrades to one bathroom and a tub to shower conversion in the master bathroom. Liam was clearly very knowledgeable, and his workmanship in both bathrooms was impeccable. He answered all my questions, had great suggestions and was very responsive whenever I needed to contact him. The demo in the master was completed in a day, and the guys cleared everything after they finished. The tile work was meticulous and just beautiful. I highly recommend Liam Neary Construction."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"I wanted a shower expanded. George Mavridis's estimate was very competitive but I hired him because I knew he was honest, quality focused and an open communicator. He has a small crew and excellent subs so he's not super fast. But Mavridis is excellent. One example: The shower needed a new fan, vented through the attic roof. The attic boards were all cut (before my time) in half when insulation was installed. The attic floor was unstable and unsafe. George was very busy but he had his team replace the boards with plywood panels...for 20% less than I expected. Why? Because he wanted to make sure I would be happy when the job was done. I could give 4-5 other examples but you get the point. If you hire George, you'll be pleased."

FAQs for addition to existing structure building service projects in Boston, 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.
