Turn an Outdated Deck Into Your Favorite Room
Your deck should fit the way you live now. Whether your existing deck is cramped, outdated, or lacks modern amenities, Allan Trant’s Exterior Finish Work provides comprehensive deck remodeling services across New Hampshire’s Seacoast and Southern NH. From expanding your deck footprint to converting wood to Trex composite, adding multi-level zones, or installing custom pergolas and lighting, we transform outdated decks into high-performance outdoor living spaces.
Important Service Distinction
Deck Remodeling vs. Resurfacing: Remodeling changes the size, layout, elevation, or added features of your deck. Resurfacing replaces boards on the exact same footprint. Allan Trant’s specializes in complete custom design-build remodels and full replacements—we do not offer patch repairs or staining services.
