I can't say enough about these folks. I had 7 quotes and selected Trant's out of all of them as my neighbor had extensive work done by them and the finished quality was outstanding. They weren't the lowest or the highest. Right in the middle, but they were the ones I felt the most comfortable with. There were 3 in the crew and the same crew worked on the project from start to finish. They were all respectful, friendly, VERY easy to deal with, and in many cases went "above and beyond". The design and quality of their work and their attention to detail was absolutely impeccable. There were no "surprises" or incidental costs added on regardless of what issues they ran into during the project. The communication was great and timely. I would hire them back for any project in a New York minute. As a matter of fact, I am having them look at another project for my son as I write.

Allan Trant’s Exterior Finish Work built a beautiful new deck at the back of our home in Dover, NH, and we couldn’t be more pleased with the results! From beginning to end, communication was excellent. Allan’s crew was talented, professional, courteous, and respectful of our property. Their attention to detail and craftsmanship were exceptional, with every measurement and finishing touch completed with great care and precision. Once the deck was finished, they returned to remove all of the debris, added crushed rock underneath the deck, and even put down topsoil and seed around the surrounding areas to give everything a clean, finished look. We absolutely love our new deck and have already recommended Allan Trant’s Exterior Finish Work to several friends. We will gladly continue to sing their praises to anyone looking to build or replace a deck. We highly recommend them!

Allan Trant’s Exterior Finish Work did our deck when we built our home in Greenland, NH, and we couldn’t be happier with the results. The attention to details was outstanding, and the entire process was professional from start to finish. Our deck has become one of our favorite parts of our home. If you’re looking for an honest contractor who delivers high-quality work, and beautiful results, I highly recommend Allan !

Can’t say enough good things about working with Allan & his team. The whole process was easy, transparent and professional. Hired them to do some work that impacted the inside and outside of a second floor window. After we contacted them they made it easy to schedule a time to meet and get a quote, understand costs, answered all my questions. They were very knowledgeable about what they were doing and how they would repair the problem. We trusted them to do the job and they did not disappoint! The team that came to do the job was well mannered and cleaned up after themselves. I can’t say I’ve ever worked with a contractor that was this put together. We recommend them and will also be using them again for future projects.

I had my deck completed last fall, and they did a wonderful job. The work was finished in a very timely manner, and they were flexible in handling additional work at a reasonable price. I would highly recommend Allan Trant’s Exterior Finish Work / AJT Properties.
