Get matched with top addition to existing structure builders in Cheltenham, MD

"To say it went perfect would be an understatement. We could not be more pleased with the craftmanship, the staff, the materials, and the professional construction we had done from this company. The photos of both bathrooms do not even do it justice because we can't capture the entire room with one photo. We have never had such amazing construction done by any contractor in the 32 years of home ownership, prior to this company. They do it all. Indoor, outdoor, heavy construction, light construction. They had to relocate HVAC ducts, plumbing, electric, and move some walls. They are a one-stop shop!! Prices were extremely reasonable."

"Additional work was needed to take the floor and walls down to studs and joists to remove rotten wood, so work took longer than originally estimated. Some items were back-ordered, adding to the length of the project. Workmanship looks excellent. I am very pleased with the new bath!"

"Requested an estimate on two building projects. The estimator arrived promptly at the time specified, took good notes and provided me a written estimate the next day.  I did not have any work performed at that time."

"We have used The North Star Companies for several jobs in the past, with the most recent being the largest. We hired them do a complete renovation of our home in Severn. The job grew larger as demo began and turned into a job requiring the rebuild of exterior walls, demo of concrete slabs - basically the house had to be rebuilt from the ground up. All new plumbing, electric, framing, windows, siding, roof, etc. I have known Chris for 20+ years and was confident that our forever home would be solid and done right. We had a few hiccups throughout the process - as this was done during Covid, so there were supply issues, delays and so forth, but Chris and his guys did an amazing job. We couldn't be happier and are continuously getting compliments on our beautiful home. Chris has been and will continue to be our go-to for any construction needs for us and our family and friends."

"I’m very excited with the outcome. I marvel every time I walk down stairs and look into my new design and functional kitchen, and living room. Updated appliances, modernized upscale look. When anyone sees the home they go from room to room the response is WOW from room to room. Wow says it all. Thank you Steve and crew. WOW"

"Néstor and his team did an outstanding job remodeling our bathroom to make it safer and more accessible for elderly family members. From start to finish, the crew was professional, efficient, and extremely respectful of our home. They completed the work quickly without cutting corners, and the quality of the craftsmanship shows in every detail. The new shower layout is exactly what we needed easy to access, thoughtfully designed, and built with long‑term safety in mind. Nestor communicated clearly throughout the project and made sure we were comfortable with every decision. We’re grateful for the care and expertise his team brought to this project and would highly recommend them to anyone looking for reliable, high quality remodeling work."

"The five-month journey that we spent with Chris, Nicoleta, Nate, Elmer and all the team at GSB Builders has beaten any of our expectations and delivered a beautiful second-floor addition, which includes a master suite and office space. After a lot of hesitation, Chris, Nicoleta and Nate convinced us to take the step forward, captured our main ideas and proposed a design that has greatly improved, not only the space and appeal of our own house, but also the neighborhood. We really appreciated their listening to our ideas, down-to-earth and professional demeanor, and knowledge about all aspects of the construction which helped us overcome our initial fears ahead of an unknown journey. The construction was well executed by a professional team led by Elmer which was always friendly, tidy and respectful of the family’s privacy while workers had to enter the house. Their work ethic and professionalism is truly impressive. We valued the extreme responsiveness of Chris and Nicoleta during critical moments, such as during a thunderstorm which damaged part of the roof under construction. The GSB Builders team reacted swiftly to repair the parts damaged by the unexpected weather conditions, which avoided further damage to the house and major disruption in the family’s life. We truly appreciated Nicoleta’s design expertise and knowledgeable guidance on choosing bathroom fixtures, and her overall warm and approachable personality, which made this project also really fun. In fact, over the course of working together, we have come to appreciate each other deeply and have come to view Nicoleta and Chris as friends of the family. No major construction project is without bumps and stress along the road, and ours was no exception. What mattered is that we were always able to rely to the GSB team to do their best to rectify any problem and solidify our trust. We will continue working with the company on other projects in the future and will recommend their service to friends and family without any hesitation."

"Very well, contractor discovered pre-existing issues and fixed them to ensure project was successful. Worked well within my budget, friendly and efficient."

"I originally hired Daniel to perform a first floor kitchen remodel which included opening up the first floor with a more open concept floor plan. And adding a kitchen island. The project went smoothly and I was so taken by the final look that I had him come back to update three bathrooms, as well as, a complete remodel the basement. The house now has a more contemporary/ modern appearance and I receive compliments often. His price points for the individual projects were fair. I found him to be not as pricey as some and a bit higher than others. The workmen were polite, cleaned up daily before leaving and very repectful of my wishes. If I had to list a con it would be that one or two of the projects were not completed on schedule. Each being off by about a week. Overall, I would hire him again and have referred him to several friends and family members."

"Wonderful! Cornelio was great to work with. He and his team were very professional and I feel like I was given their time and attention. Cornelio was always very responsive and helpful in decisions that we had to make. We moved out for the renovation and were out of town for part of it and he often sent me pictures in the evenings so I could see the progress. We have lived in our home for 7.5 years so we had a good feeling for what we needed. We hired an architect and a designer separately and that was helpful as we went in prepared with what we wanted done. Cornelio and his team took out a wall and a half bathroom and removed most of the plaster (we live in a 1930's row house in Washington, DC). He also built us a new half bathroom and rebuilt walls and doors that needed to be done. When he took out the plaster and such he found old pipes and wires that needed replacing and took care of it. He didn't ask for more money it was included in the work. One thing that really impressed me is we decided to keep our old cabinets and have them painted (by a separate company). When his guys took them off the wall they were damaged (not because of the guys negligence, they had been cement glued to the walls instead of screwed into the walls as they should have been. Cornelio made sure they were repaired and installed in a much better and safer way and you can't tell at all! We love our new kitchen and half bathroom so much! It makes our house much more comfortable and usable for our family!"
