"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."

"
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."

"We found Strong Builders by searching the internet and reading reviews. We feel very lucky to have connected with Jack to discuss our rather complex home renovation project, including adding a master bedroom above the garage, connecting the upper level to the existing house, and a large addition off the back. Jack worked with us to come up with a design that met our vision and provided a very detailed work plan that gave us a clear understanding of the timeline, cost, and overall scope of the project. This made it very transparent when we decided to add extras or to exclude some options. Jack is a professional. He takes pride in his work and valued our time. He was on the job personally each day working or supervising any sub-contracting work that was necessary and the project was completed on-time and on budget. We would not hesitate to recommend Jack for any project large or small and are so excited to be enjoying our â newâ home! Thanks Jack!"

"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."

"The Gowdy Group was great. Did a full bathroom remodel (removed everything, tore down to the studs) and had it all replaced. Ted was easy to work with from initial design through the final fit and finish. Smooth project, great result, and his price was far better than the other folks we talked to as well."

"My house needed to be repaired from a huge fire. I was looking for a GC that has extensive knowledge of fire damage. After multiple quotes, I chose WS Builders because the owner was very professional and knew what he was talking about. Wladimir assisted me from beginning to end. We gutted the whole house and replace all the electricity. This was a big project and it was necessary to find a GC who had previous experience in rebuilding a house damaged by fire. I am very please with Wladimir's work ethic and professionalism. He had a quick turnaround and communicated thoroughly to ensure that I fully understand what was going on during the project. I recommend using him if you are looking for somebody with years of experience. Regardless of what job it is, he has the subcontractors to ensure the job is completed in a timely manner."

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