"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.

"
Antonio communicated clearly with me, every step of the construction process.  After removing the siding, there was additional water damage underneath that required additional work.  He carefully showed me and explained what had to be done, and we revised the scope of the work.  My husband and I felt that he showed a lot of honesty and integrity in carefully outlining and showing us additional work needed, that could not be seen until the siding was removed. We felt he was very fair with us in his pricing for the scope of the work.

He helped us review the composite siding options and warranties, and brought us samples for the siding and decking, at different price points and explained in detail differences between each. He and his crew came punctually and on the schedule that Antonio had laid out for us.  They were meticulous in their clean-up as well.

The quality of Antonio's work, as well as his careful product research and commitment to our satisfaction, totally surpassed our expectations.  We do not hesitate in recommending Antonio, and plan to have him renovate our bathroom in the Spring."

"Joe and his team are truly amazing to work with and their product is even better. I am an architect and have worked with Joe on several projects. I am always really happy to see their results, Joe makes sure to take care of everything so that it is done professionally, up to all building and code standards, and that it looks spectacular in the end. It's hard to find a GC that cares and is willing to go the extra mile for their client. Joe is someone I trust completely to get it done well and to listen to the clients need. I recommend him 100%"

"Excellent. We had a great experience and are more than satisfied with the work they performed. Derek and James remodeled our bathroom several years ago and we were very pleased then and immediately thought to contact them when we had some water damage to part of the exterior on the back room of our house. In addition to replacing the damaged clapboards, there was underlying structural repairs and carpentry/insulation work needed on all the windows. Derek and James responded immediately so we were able to get the work done before more water damage could occur. They do quality work, are attentive to detail, communicate well and clean up their workspace everyday. While here, we also had them repoint the stone foundation of the house to prevent and water leaks/rodent entry. They did a great job on that project, too. Couldn't be more pleased."

"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."

"Three terms you don't hear when speaking about contractors : Honesty, timely and effecient and pride of Workmanship. If you use Liam Neary Construction you will be using these terms and smiling as you tell others about your amazing experience. I had a leak in my roof with water coming in through the chimney. The water came into the utilitiy room creating a mini swimming pool and the hot water tank shut down. Liam came out within an hour of my phone call got my water running showed me how to clean the sensor for the future and reset the hot water tank. He scheduled to come out later that day to replace flashing on the roof to hopefully fix the problem. Unfortunately for me, it was not the full resolution. In the next rainstorm, I got water in the chimney again and reached out to Liam. This time it was a saturday and was thinking I might see him at the start of the work week or need to pay crazy money just to get him to show up. This was not my experience he showed up in 2 hours reviewed what he had done and come up with a new solution. He determined that the chimney needed some additional work and adjusted the price because of the original work that he had done correctly, but did not solve the problem completely. This contractor is the real deal. If you have a problem give him a call today. He will make your life easier and resolve your problems quickly. For the job done right call Liam Neary."

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.
