"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"

"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."

"
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."

"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 had Jesse and crew at my house for 2 separate projects and I couldn't be happier. The first project was a small deck. Jesse set proper expectations about when he could complete the work (he's busy!) and provided an estimate. We stayed in contact regularly until he was able to start the project. I was very happy with the finished product and appreciated how they always cleaned up the site at the end of the day. The final bill was exactly what he quoted me. Since my first experience with Jesse was so positive, he was the first person I called when a tree fell on my roof during our last windstorm. Jesse came right over, assessed the situation and quickly determined that the limb went through the roof. With rain in the forecast, Jesse immediately sent a lift truck to my house (I have a 40 ft roof) and sent a crew to repair the roof that day. I was so impressed with the speed and urgency in which he and his crew worked to fix the problem. Again, his estimate was accurate and there were no surprises. Jesse is always a pleasure to work with. He and his team are professional, courteous and knowledgeable. I will definitely use them again for future projects."

"Vinny is a fantastic contractor to work with. I have had Vinny work on multiple renovation projects at our home over the last year and half, and have had nothing but positive experience. He is humble, very professional, responsive, no shortcuts, hard working, and perfection in every work he does. He is punctual and prompt on his schedule. He has a great network of contacts for other trades (plumbing, electrical, plastering, hvac, you name it) and helps identify the right people to use for the job. Based on my experience, every single one of them that came with his recommendation were great to work with. I would absolutely recommend Vinny and VC Construction for any home renovation projects, and would not hesitate a bit to hire him for any future projects."

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