617-719-4200 Alexis Home Remodeling started few years after the purchase of my first home in Boston back in 1992. This triple decker built in 1906 needed more than just a paint job, it needed reliable, honest and motivated professionals. Many hours of waiting for call backs made me think I could do a better job at it. That's why I treat everyone of my customers as I would have want these no show contractors treat me with the respect and professionalism I deserved. Since 1996, Alexis Home Remodeling has walked home owners from the remodeling concept to the finish product. We are fully licensed and insured.

"Edison and his two staff did a great job move and install my Titan message chair to my living room from first floor. Highly recommended!"

We do mainly Baths, Kitchens and Basements renovations, starting with demolition and delivering a final product, including carpentry, electric, plumbing, tiling, painting and cabinets installation. However, any kind of renovations are welcomed. Interior Designer, Architect and Structural Engineers available. Our professionals are all Licensed and Insured.

"Joe and his team did an incredible job, the work was excellent and I appreciated the workmanship and the creative trouble-shooting (it's an old house!) to get excellent results. Everyone on his team was great: skilled, hard-working, friendly, and kind/respectful. Pricing was very reasonable and allowed me to upgrade items like appliances without sacrificing the scope of the remodel, quality, or workmanship. My house is transformed and I could not be happier with the results."

"I highly recommend Sanfer Rocha and D.S. Partners Construction for a bathroom remodel. Sanfer was professional, transparent with costs, and responsive to questions during the whole renovation process. His workers were skilled, prompt, and friendly. Sanfer also suggested vendors and provided helpful tips. I am very happy with our beautiful bathroom and would hire him again for another renovation."

iCornerstone offers design through construction services and promotes Consumer Controlled Construction as a solution to over-pricing, under performance, unrealistic allowances, and quality issues. We provide designs, labor and material specifications, accurate project costs, camera monitoring, invoice review, project accounting, and construction support that allow the homeowner to act as the general contractor easily and with a minimal time commitment. The first three carry an hourly rate of $100, while the fourth is 15% of the cost of the work as you have defined it. After a free Initial Consultation, we provide a proposal for the cost of our services. Our platform networks regulators, engineers, subcontractors, service providers, and suppliers involved in your project so that everyone knows what everyone else knows, which is the hallmark of transparency and accountability. Everyone is on the same page. Their E-folios resolve the dilemma of "If only I had known, I would have asked." Everyone benefits, and nothing like the platform exists in the industry. Clients must provide us the names of subcontractors we do not know as a means of proving to themselves we do not steer business or have a conflict of interest. This strategy helps our network grow and ensures fairness. Our free, online, Consumer E-Folio / Project Organizer / Property Profile / Research Tool will help you, even if you do not involve us in your project, comes with no strings attached, and respects your privacy. Simply register at icornerstoneinc.com and have fun using it. We claim three remarkable achievements: no client has ever gone over budget; no subcontractor has ever been overpaid or unpaid without cause; and all clients receive the highest quality at the lowest price.

"Richard and all of his subcontractors were wonderful to work with. He is so thoughtful and kind. It is clear that he loves what he does! Every detail is thought through and he is great at problem solving when things pop up along the way. If you’re questioning whether to go with him - just do it! He is a great communicator and you’ll always feel you’re on the same team."

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

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