"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!"

"I had an excellent experience with The Curtice Group. I would highly recommend them and I'd use them again for a future project. We utilized the full design to build service to add a master bedroom/bath/closet, a 2nd floor 3x10 balcony, and renovate a number of items associated with the build including a re-build of an existing bathroom.  We live in an old house and Scott did a fantastic job making use of space and working with the house limitations, and overall, giving us lots of details and options as we had back/forth meetings on the concept.  The design process was great. We had a number of meetings starting from a wish list that expanded to initial design concepts and then to more final concepts. Scott made excellent use of space and gave us a lot of options which for budget reasons, we had to slowly narrow things down to a final concept. The build was equally fantastic. Not only was the quality extremely high but they stayed on schedule and never skipped days; there was always a team working every day. The workers and subs were reliable and on schedule, which you dont see too much of. Not only that but juggling/managing the schedule when the different subs had to show up was very impressive as the goals for each week were always met. Scott and his team really care to make a top-quality build. A few family members in construction walked through a few times and commented on the high quality of everything.  The house had two surprises as we things opened up.  Somewhat expected as unwelcome as it was: a bad foundation and a roof with upgrades needed. Both these items were attended to very quickly and surprisingly got back on track sooner than I thought it would.  Budget: Scott's budget was extremely accurate. Aside from the 2 house surprises (above) and the additional rise in lumber cost during COVID, all numbers and quotes lined up extremely well. Yes the cost went over the estimate but I hold no concern over this, since it was due to two extra side projects (that were impressive accomplishments). When the project was done Scott made sure we were happy with everything. A few items to touch up were quickly dealt with and Scott really went above and beyond making sure things were 100%. No negative comments from me. Any items to nit-pick are not worth putting in a review: this was an extremely positive experience and I would recommend the Curtice Group and would/will certainly utilize them again in the future."

"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%"

"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."

"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!"

"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 Waltham, 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.
