Customers say: True professional

"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.   <br /> 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. <br />"

"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."

"Humberto and his crew were fantastic and we will definitely hire them again for future projects. The quality of work is amazing. We're so happy with our new rooms! Humberto scheduled the first day of work within a week of us contacting him. He responded to all emails within the same day and always arrived on time or even early! In addition, Humberto and his crew were professional, courteous, and very neat. I highly recommend HS Plastering & Painting."

"They were excellent! We had some some serious structural issues with our garage. They were honest about the work and communicated with us daily. He hired a subcontractor for some of the work but ensured that the subcontractor worked up to his and our standards. The crew went above and beyond! We WILL be hiring them again for future projects."

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