Get matched with top building designers in East-derry, NH

"I had an addition I wanted for our home. We were required to have a survey and an engineer drawing to apply for the permit. I had a list of 10-15 local engineering companies given to me by the permitting office. Very few would return my call. several the rest said they only do commercial or that this was too small of a job and would cost more. It was taking months and I was frustrated and decided to try Angie’s. I am so pleased. I had a response that very day I inquired for the job. It was clear what was needed from me. Great communication and answered questions to help me get them what they needed. The project from start to finish was drafted within 3 weeks. It could have been done sooner but I was traveling and not able to check emails. Once I told them to text me to alert me of an email they did that. I would highly recommend them."

"Great, Dave stayed within our budget and our addition looks like it was part of a whole new home construction. We were really impressed with Dave Kinsella's design concepts and the workmanship was high quality even though we were on a tight budget. Dave comes from a big family so he understands money and time constraints plus he wants his projects to look as aesthetically pleasing to his clients as possible. We would definitely hire Dave again."

"It was a pleasure to work with Paul. This was the first project I have done that came in on time and on budget. Excellent work and no complaints worthy of mentioning. He is honest, straightforward and has a sense of humor. I highly recommend him for projects up to an addition. "

"Excellent. Paul and his team are friendly and a pleasure to work with. They worked fast and efficiently and were great on price. Will be hiring them again."

"We started out looking for an architect/designer, and met the owner of Tseranos Construction, Sterg, in the process. He referred us to a design architect, which we used, and we ended up then hiring Tseranos Construction as our general contractor. Sterg was really great to work with. He found ways to keep costs down while doing everything that we wanted to have done. In the end, the garage construction project took about 5 months, but we are thrilled with the results. Would hire Sterg again for future projects."

"Hossein Vahedi of CLASSICAL HOMES LLC designed our house and supervised the construction process. He was friendly and easy to work with, had many creative ideas, and really tried to understand our needs. He worked well with our general contractor. His price is very reasonable. I highly recommend him to people who want to create their own dream house, but need professional help to translate their ideas to doable project."

"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."

"Hired this company for summer 2019 to open/close and clean weekly. In the month we used SSG, the pool was not cleaned properly once. 25 tiles were damaged mysteriously upon open, there were leaves and dirt left in the pool the entire time and we have not been able to use the pool yet. We expressed our disappointment and gave them more than enough chances to rectify things. They didn't. Pictures attached are from our pool and spa today - after the tech "cleaned" and left a bill for over $200. Absolutely horrible. Terminated contract."
