American Building & Design, LLC describes itself on Angi as a New Hampshire based remodeling construction company, and on its own website it says it has over 30 years in business, with work ranging from new home construction to remodeling, renovation and cabinetmaking. Its website names Dover as a service area. A 2025 Google customer said George Trojan Junior, who owns the company, installed cabinets they had bought from dovetail cabinets in Portsmouth, NH, scribing them to the floor so no trim was needed at the bottom. That customer said the home was built in the 1800s and nothing was square. The same 2025 customer said George also installed doors on a laundry room and did tile work in a bathroom, after they did the kitchen tear-out and electrical work themselves. A 2021 Google customer said they renovated their kitchen with George and that he worked through each unexpected moment that came up in the project. In a 2013 Angi review, a customer described a project of several months and said George was on the job daily as the organizer and project manager, suggesting design changes while staying true to the style of the house. In a 2012 Angi review, a customer said George, the owner, did much of the work himself and was on site every day. That 2012 customer said the price grew as the work went on, for reasons that made sense, and that his quotes, invoices and change-order documents were well organized. Their one criticism in 2012 was that George sometimes should have told them bad news bluntly; they wrote that had he asked for a few more days instead of rushing to meet their deadline, their move-in might have been smoother. Google shows 5 stars from 12 ratings, and the Better Business Bureau gives the company an A+ grade.

I purchased my cabinets from dovetail cabinets in Portsmouth, NH. I interviewed several cabinet installers and was not impressed with their lack of knowledge. One contractor I did interview was George Trojan Junior who owns American Building And Design. George is a fantastic carpenter who I call a carpenter mechanic because his knowledge is extensive and technically on point with everything he does. My cabinets were installed perfectly no trim was needed on the bottom of the cabinets, everything was scribed to the floor. My home was built in the 1800’s and nothing was square and George made everything look perfect. George installed doors on my laundry room perfectly and did some tile work in my bathroom that was done impeccably well. I recommend George over any contractor I’ve ever dealt with. I did to tear out in my kitchen myself and the electrical work and George did the rest and it was fantastic. I can’t say enough about his work.
I highly recommend working with George on any of your home construction needs. I recently renovated my kitchen and could not be happier with the outcome! (see before and after photos below) George's attention to detail is spot on. There were plenty of "oh, didn't expect that" moments when working through the project, but George worked through each and everything came out really well! On top of quality work, George is responsive and professional.
This young man is incredibly skilled in all areas of building and his conscientious attention to excellence in quality workmanship results in a finished product that will meet the highest standards of the most discriminating customer. The fact that he is on the job daily as the organizer and project manager makes him accessible and accountable to the customer. His willingness to communicate problems, suggestions, and solutions, allows the customer to have input on even the most minor details throughout the project so they get the results they want. His energy and desire to please the customer and his friendly, respectful, and professional demeanor make him easy to talk to and work with and instill confidence that his experience and abilities are suited to any task you charge him with. George is a builder by vocation and he is blessed with good judgment, good design, and skills that are obvious in the flawless finish work not only in precise joinery but in his tendency to go the extra mile to put in the extra work and time to make everything as beautiful as possible. This was a massive project with thousands of details and decisions that had to be made over several months and I cannot find a single example of sloppy or below par workmanship. He was brilliant in suggesting design changes that he believed would enhance not only the quality of the work but the beauty of the finished design and most importantly, he remained true to the style of the house with a keen eye to appropriateness and proportion. If you are for fortunate enough to be able to enlist the services of the much in demand craftsman, you will not be disappointed and you will certainly get your money's worth and be delighted with the results. I personally could not be more pleased with his work.Show moreJudy A O.
George is always on time, has been honest and trustworthy. He always keeps me up-to-date on progress. His work is always outstanding! I don't even consider anyone else to do work.
George Trojan, the owner of the company, is also the one who does much of the work. He is on-site every day and takes great pride in his work. He is a carpenter in his soul. We were very happy with his work, and in our communications with George. He made many helpful suggestions, and communicated well when change orders had to be made to the work. He worked well both my wife and I, and made us comfortable. The price tag of our work grew with the doing, but for reasons that made sense, once we knew what we had to deal with. All of his quotes, invoices and change order documents were well organized, complete, and sensible. His suggestions greatly improved the quality of the finished project. The work was done as quickly as one could expect. He was on the project full time. Our only criticism is that George worked very hard to make us happy -- sometimes it would have been better to tell us bad news bluntly. (there will always be bad news in a project of this scope in an old house). Had he said that he needed a few more days to finish up, instead of rushing to meet our deadline, the end and our move in might have been smoother. (He did work very long hours at the end!) And at the beginning, he was a bit reluctant to tell us when we were asking for something that was a bit silly (we are not experts in this kind of thing!). But that is a minor issue. We were very happy working with George. He did a very good job, and we have recommended him already to several of our friends who are moving into new houses.
