"Eric and co are the best - attentive, listen, give their professional advice, and just do a great job. The project went really well - repaired water and bug damage and fixed what was originally done in a not so great manner. Our third successful project w/ Eric and team. Very pleased"

Customers say: True professional

"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."

"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"Excellent. We had a great experience and are more than satisfied with the work they performed. Derek and James remodeled our bathroom several years ago and we were very pleased then and immediately thought to contact them when we had some water damage to part of the exterior on the back room of our house. In addition to replacing the damaged clapboards, there was underlying structural repairs and carpentry/insulation work needed on all the windows. Derek and James responded immediately so we were able to get the work done before more water damage could occur. They do quality work, are attentive to detail, communicate well and clean up their workspace everyday. While here, we also had them repoint the stone foundation of the house to prevent and water leaks/rodent entry. They did a great job on that project, too. Couldn't be more pleased."

"I hit the jackpot when I chose Bob Ayotte to build my accessory dwelling unit in my son's 2 car garage. I should have purchased a lottery ticket! He is honest, a perfectionist, neat and very knowledgeable! Most impressive for me was the fact that Bob took the time to listen and understand what I needed to make this dwelling my "forever place" now that I have retired."

"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."

"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."

"Monique, Eduardo and their team were amazing to work with. I would recommend them to anyone. They did an incredible job on my house renovation. Everything was organized efficiently making it easy and hassle-free. They took care of it all: plumbing, electrical, painting, floor sanding and finishing, carpentry, guttering repairs, etc. The project was on budget and on schedule. The whole team were professional, courteous and punctual. They went above and beyond to make a 160 year old house look beautiful."

FAQs for addition to existing structure building service projects in Nashua, NH

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.
