At Complete Exterior, we believe your outdoor living space should be as comfortable and inviting as the inside of your home. Our expert team specializes in custom deck design and installation throughout New Hampshire. Whether you’re looking for a new build, a replacement deck, or an upgrade with premium railing systems, we deliver quality craftsmanship that lasts for decades.
We proudly install composite decking from industry leaders Trex and TimberTech, both known for their innovation, style, and longevity. Unlike traditional wood, composite decks resist warping, rotting, and insect damage, making them low-maintenance and long-lasting. Available in a variety of colors, textures, and finishes, Trex and TimberTech allow you to achieve the look you want without the upkeep.
No deck is complete without a railing that balances safety and style. That’s why offer a range of vinyl, aluminum, and composite options to complement your deck design. From sleek, modern lines to classic profiles, railings deliver both beauty and durability, ensuring your outdoor space is safe and inviting.
Every home is different, and so is every homeowner’s vision. Our deck experts work closely with you to design a deck that matches your lifestyle and enhances your property’s curb appeal. From multi-level decks with built-in seating to simple backyard platforms, we tailor every project to your goals and budget.
With years of experience, our installation team brings precision and attention to detail to every job. We use proven techniques and the best materials to ensure your deck is structurally sound, visually stunning, and built to withstand New England’s tough weather conditions. We don’t cut corners—your satisfaction is our priority.
