Get matched with top addition to existing structure builders in Concord, NH

"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"

"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!"

"Everything went very well. Had to push the start date past winter. Matt is very responsive on the phone and the guys were on time and finished the job in 2 days. Nice group of guys would definitely use for more extensive work."

"The Curtis Group was hired to Design, Contract Manage and build an addition as well as remodel Kitchen, replace roof and paint both exterior and interior of main house and addition. Both Eric and Scott and their entire Team were excellent to work with."

"We worked primarily with James to have a skylight installed in our recently constructed bathroom, as well as replacing an existing window in a bedroom, and adding a storm door. He was prompt and communicative, and very diligent about ensuring the space was clean and tidy after the work was completed. We are very happy with the installation of the windows and storm door and would recommend!"

"
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."

"Full gut reno of basement into 2 new bedrooms and bathroom. This was a complete demo job and new build out of basement. Bob and his team did an amazing job with great vision, expertise and quality. 100% recommend."

"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."

"We recently hired HS General Contracting for multiple indoor and outdoor projects at our home. As always, Humberto's company provided excellent communication and follow up throughout the duration of the project. We highly recommend HS."

"Gil and his team did an outstanding job on our staircase renovation. They rebuilt the banister, handled the drywall, and refinished, and everything came out incredibly clean and precise. The craftsmanship really stands out, from the smooth lines of the railing to the attention to detail around the steps and finishes. The space feels completely transformed. They kept the work area tidy throughout and were professional from start to finish. Solid, high-quality work, I would absolutely recommend them."
