Exceptional craftsmanship and outstanding quality. Despite unexpected challenges like exposing rot, they adapted quickly and delivered within the original timeline. Special thanks to Ed in sales, owner Luis, and the entire team on-site.

A1 Professional came quickly to give me a quote for a large deck. Gave me a great price and started on time. They took care of permits and was here every day until they finished. They are the best I’ve ever worked with!!
Nicolas Kensington
Great design and build — new deck, clearing trees and a pathway to my lake. Quality exceeded expectations, completion time was impressive and the price was reasonable. Will use them again.

Great guys to work with. My chimney replacement looks great. Company is very responsive, got back to me with an estimate within the week after inquiring about the leak around my chimney.

A1 Professional did a great job installing siding on our home. The crew is neat, professional and hard-working. Everyone is polite and easy to work with. We are so pleased and will be happy to recommend them in the future. Well done!
Roof replacement costs in NH and VT vary based on the size of the home, roof pitch, selected material, and the condition of the existing structure. A1 Pro provides free written estimates with a full breakdown, so you know exactly what you are paying for before making a commitment.
Most projects are completed within 1 to 3 days once materials are on site, and the schedule is set. Larger or more complex jobs, such as multi-level decks, full siding replacements, or roofs with significant structural repairs, can take longer. A1 Pro gives you a realistic timeline at the estimate stage, not after the work starts.
A manufacturer’s warranty covers the materials themselves (shingles, composite decking, siding panels, gutter systems) against defects and premature failure. A1 Pro’s craftsmanship warranty covers the quality of the installation itself. Both are delivered in writing at project close, and the craftsmanship warranty is transferable if you sell your home.
It depends on the cause of damage. Storm damage, ice dams, and wind events are typically covered under standard homeowner’s insurance policies. Damage from age or deferred maintenance generally is not. A1 Pro can document the condition of your roof or siding during the estimate process, which can support an insurance claim if the damage qualifies.
In most cases, yes. New Hampshire and Vermont both require building permits for structural work, including deck installations and many siding replacements. The specific requirements vary by municipality. A1 Pro handles all permitting on every job, so if your project needs a permit, we pull it before any work begins.
