Custom, multi-level, composite and pool decks lead the services list on the website of Allan Trant’s Exterior Finish Work, alongside pergolas, porches and gazebo and pavilion construction. The company says it has been in business 12 years and names a service area that includes Portsmouth, Exeter, Hampton, Dover, Durham and Barrington. On Google it holds 5 stars from 22 ratings. A recent customer in Dover said the company built a new deck at the back of their home, and that once the deck was finished they returned to remove the debris, add crushed rock underneath and put down topsoil and seed around it. A recent customer who collected 7 quotes said they picked Trant's, which was neither the lowest nor the highest, after a neighbor had extensive work done by them. That customer said the same 3-person crew worked the project from start to finish and that no incidental costs were added regardless of the issues that came up. A recent customer in Greenland said the company did their deck when they built their home there. A 2026 customer said they hired the team for work affecting the inside and outside of a second-floor window, and that the team cleaned up after themselves. A 2025 customer said the team extended their deck and built a storage area under it, showing up on time every day of the project. A 2025 customer said they received the contract and certificate of insurance quickly, and their condo board approved the addition in less than 24 hours. A 2025 customer said Allan re-sided the entire left side of their house after hail damage and stayed on budget, and that five years later the CertainTeed siding still matched the rest of the house.
