A well-built frame offers a safe place for family gatherings. As your trusted deck builder in Farmington, NH, we construct strong structures that increase your property value. Our team calculates load-bearing capacities to ensure total safety. We handle all necessary building permits for your convenience. You get a functional layout that naturally extends your living area. We build these exterior upgrades to last for decades.
We build a custom deck around your lot, your views, and your daily routine. Our deck installation in Farmington covers layout, framing, and finishing details. Want a wraparound for entertaining or a quiet corner for morning coffee? We bring your ideas to life with custom deck building in Farmington that reflects your style and respects local conditions.
For homeowners who want lasting beauty without yearly sanding, composite decks are a smart pick. We work with Trex and TimberTech, which resist fading, rot, and warping in New England's wet, cold climate. These decking materials keep their color for decades and shrug off snow and rain. You get a clean, modern look that needs little more than a quick rinse each season.
Tired boards and loose railings drag down your whole yard. As your deck contractor in Farmington for upgrades, we resurface aging decks and replace worn framing where needed. Resurfacing typically costs less than a full rebuild while giving you a fresh, safe surface. We inspect the structure first, then refresh the parts that matter so your deck feels brand new.
A deck becomes a true retreat when you add the right structures. We build pergolas, screened porches, and covered areas that extend your season and shade you from summer sun. These additions create defined spaces for dining, lounging, or hosting friends. Every structure ties into your existing layout for a seamless, finished look that adds real value to your home.
The small touches make a big difference. We install built-in benches, planters, lighting, and railing systems that match your taste and improve safety. Thoughtful features like step lighting help you enjoy your space after dark. We tailor each detail to your needs so your deck works as hard as it looks good, day or night, all year long.
Beyond decks, we handle siding repair and exterior carpentry that protect your home's envelope. We fix trim, replace damaged panels, and seal openings to keep water out and prevent rot. These repairs guard your home's structure and keep its appearance sharp. One trusted crew handles your deck and your exterior, so the whole job stays consistent and clean.

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.Posted on Google![]()

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!Posted on Google![]()

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.Posted on Google![]()
