"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.

"Our existing bathroom was a half bathroom with sink vanity, toilet, washer and dryer. We needed to eliminate laundry equipment and add shower and closet in the space that was designated for a washer and dryer, and add outside venting. We also wanted to tile the whole bathroom up to the ceiling. The job was performed excellent and we are very happy with the choices we made. Bill Perry and his crew were working in our house before renovating basement and building rooms there, so we knew that they were the best company for us. They were great giving us advice to improve on things that we wanted done, so they look and work better with a given space. We are very happy again. Thank you Perry Brothers!"

"Every aspect of this project, from planning and architectural work to contractors, sub contractors and coordination was 100%. I received a spreadsheet every week with expenses as compared to budget including all materials and labor. Each step of the project including consultations, advice for saving $$ as well as suggestions for improvements in existing HVAC systems were valuable. All contractors were 100% reliable, professional, were creative and constructive in addressing challenges that emerge in any project and demonstrated outstanding follow through. The shop is extremely comfortable even on the coldest days and maintains even humidity for the wood. The project was on budget, on time and exceeded expectations, particularly with regard to workmanship, communication and professionalism."

"
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 did an excellent job with our basement! Joe is very responsive, managed all parts of the project very well, including permitting, solving new issues that came up unexpectedly, responding to inspector needs, addressing our additions to the projects, and trying his best to meet all our timelines. Even if things got delayed in some parts, it was very helpful that Joe was always able to communicate and keep us posted on where things stand. The pricing was fair, and I could trust Joe to provide good advice on the right services and materials to use. I recommend Joe for any home project and would be happy to use Silmac services again."

"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."

"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."

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.
