Testimonials

Pauline Rock

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!

Yasmina 001

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 !

Kristy Osborne

The craftsmanship on our front entry stairs is top-notch and exactly what we wanted! Allan and team really take pride in their work and the project went smoothly from start to finish. Very happy with the result.

Alexandra Roy

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.

Stephen Myong

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.

Keenan Duffy

I couldn’t be happier with the work and outcome of my new deck build. Allan was a pleasure to work with and would highly recommend him to anyone.

Ginny Boutchie Antell

This was a great experience. Stephanie is a true professional! We received contract and certificate of insurance quickly and our condo board approved the addition in less than 24 hours! Alan and crew did our back deck when our home was being built. His master craftsman work was just what we required for our home. Michael and I are happy with our front porch railing. It finishes our home completely. Thank you!
