"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!"

"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat.

"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 and his crew remodeled our front hall, completely relocated /
rebuilt our kitchen, and converted our 3 season porch into a heated
sun room. They did everything from the demo work to the final touches of
installing the back splash.
Antonio and his crew, (and I'm lumping in his
subs for the plumbing and electrical parts here), did an outstanding
job on our renovation project. Renovation projects can be stressful and
Antonio did a great job through the whole project. He was always
reachable when we had a question or a concern and always made it a
priority to make sure we were satisfied with the results. In some cases that meant working with us on what we wanted, leaving out samples for us to look at when we got home, or even sending picture text messages to make sure it's what we wanted before doing it. It's those types of things that make a big difference in the final result.
All renovation project encounter problems. In our case we had a few design
issues as well as delays with our counter tops that held up plumbing install and a few other things. First off these are problems that were not caused by
  Antonio's team but rather reinforce the need to hire a team like them who can help you through it and work around it.
Finding the right contractor is as much
about personality fit as it is about finding one with the right skill set. I'm going to level with you. My wife and I can be tough customers. An engineer and   and architectual designer by trade, I'll admit we can be picky about certain parts of the project. Maybe that's an understatement, I don't know, but more importantly I think that says something about our contractor. You have to Antonio for his patience, attention to detail and pride in his work. They were evident throughout the project and most importantly in the final result. I have no reservations about hiring him and his team again for future work to our home.
Of the 2 other bids we considered for this project, I'm glad we went"

"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."

"I hired US ProPaint and Renovation after meeting JR, discussing my project, and receiving what I thought was a fair and thorough proposal describing the work to be completed in 2 bathrooms. The team that worked in my home was professional, and they arrived on time each day. They were very careful to clean up after themselves each day. JR and his team also made sure, for each key piece of the project, that products were installed as I wanted them and that I was pleased with their progress. The team removed a vanity and granite countertops, installed a new bathroom vanity, installed LVT flooring in 2 bathrooms with transitions to meet the existing wood floors, installed new toilets, and then painted ceilings, doors, trim, and walls. The entire process was excellent and the best experience I’ve had with a company doing renovation work in my home. I’d use US ProPaint again and have recommended them to others."

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