"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"First of all I am EXTREMELY fussy about any work done on our antique farm. That said, Vanni does a super job. The most meticulous carpenter I have ever worked with. Great attention to even the smallest detail. He is affable, prompt, honest, reliable and a true master of his trade. Furthermore he cleans up ALL mess before leaving each night. As stated we own an antique farmhouse with four barns/out buildings and consequently have dealt with a multitude of contractors over the years. He is the best carpenter by a long shot. If you want the best workmanship you need not shop around. Do yourself a favor and hire him."

"Highly recommended. Jose and Cesar were great. They were reliable and their work was excellent. They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

"Wallpaper removal = A; plastering = A-; painting: C+. We were disappointed in the overall experience. They were kind enough and their wallpaper removal and plastering was great, really solid—but on the final day, they rushed with the painting to get it done on the original time frame, and while one room was top notch, another was above average, and the bathroom was very sloppy. There was wall paint on our bathroom tiles, vanity, and shower; unsanded/unsmoothed plaster chunks that were just painted right over and were unsightly and lumpy; peeling caulking; parts where the paint was crooked or misaligned with baseboards; paint dribbles on floor and utensils on counter; and they did a poor job cleaning up, with plaster dust everywhere, paint to be cleaned up in the bathroom, and paint and plaster dust in, on, and around our cabinets. One of the crew members’ painting skills was just rushed and poor and it detracted from the others’ skills. By the time the job was over they rushed to get out of the house and did not carefully complete a walkthrough."

"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."

"Joe and Jonathan are amazing. Joe was quick to provide us with an estimate, they were easy to schedule us, and they kept us up to date with all of the progress and checked in about anything that came up. Joe was very conscious of the cost of the things that were being changed and added, and made sure we knew what we were getting ourselves into. The upstairs bathroom looks refreshed, and the basement bathroom is unrecognizable; it is a functional space that is clean and inviting. We trusted their work so much that we have had them back to do additional work around the house. We've been very pleased with their ability to execute on such varied projects, including repairing rot, changing out the tile in our front entrance, and replacing our bulkhead door."

Customers say: Quality work

"As busy and in-demand as this, high quality company was, the owner and team worked around their schedule to provide a prompt assessment, quote, and coordination for the renovation work on family room that had been partially flooded from a water tank leak. They were efficient and also were attentive to detail, including set up and clean up."

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