We specialize in designing and constructing custom decks for homeowners across Southern New Hampshire, delivering high-quality craftsmanship, durable materials, and tailored solutions. Whether you’re dreaming of a cozy retreat or a spacious area to entertain guests, our experienced team is here to bring your vision to life.
We understand that every home and homeowner has unique needs. That’s why we work closely with you to create a deck that complements your home’s architecture, fits your yard, and aligns with your budget. From concept to completion, our goal is to make the process smooth, efficient, and rewarding.
High-Quality Deck Materials Built for New Hampshire Weather
The New England climate can be tough on exterior structures, which is why material choice is a key part of any deck building project. At McCarthy Exteriors, we offer a range of decking options suited to withstand the cold winters, hot summers, and everything in between.
Our selection includes pressure-treated wood for its affordability and strength, composite decking for low maintenance and long-lasting performance, and
LPE hardwoods for a luxurious, natural finish. We help you evaluate your options based on aesthetics, durability, upkeep, and cost, so you get the right deck for your lifestyle and environment.
All our decks are built using corrosion-resistant fasteners and weather-resistant framing methods that ensure long-term stability and structural integrity.
Expert Construction from Trusted Southern NH Deck Contractors
When you choose McCarthy Exteriors, you’re choosing a team of experienced, licensed professionals who follow best practices and local building codes to deliver safe, long-lasting results. Our deck contractors in Southern NH handle every phase of the build from excavation and footings to framing, decking, and finishing details.
We begin by assessing your property, designing the structure for optimal use of space, and ensuring proper drainage and support. During construction, we pay close attention to layout, safety, and durability. Our crews are courteous, efficient, and clean, treating your property with respect and minimizing disruption to your daily life.
You can trust us to manage inspections, permits, and timelines while keeping you informed every step of the way.
Energy-Efficient and Low-Maintenance Decking Options
Today’s homeowners are looking for decks that don’t just look great—they also need to be energy-efficient, sustainable, and easy to maintain. At McCarthy Exteriors, we build custom decks using modern materials that minimize maintenance and maximize comfort.
Composite and capped composite decking options resist moisture, fading, and insects without requiring annual sealing or staining. We also offer railing systems, under-deck drainage, and deck lighting that add function and style without increasing upkeep. Our design recommendations prioritize convenience and long-term value, helping you enjoy your outdoor space more while spending less time maintaining it.
For those who prefer a natural look, we also offer sustainably harvested hardwoods and advanced protective coatings that preserve the color and finish of your deck for years to come.

Larry Bruno
Tyler and his crew were awesome to work with. They were efficient with all their work and materials and left a fantastic finished product. I would highly recommend them to any family or friends for any of their projects. I went with a Harie siding product on my home and was nervous of hiring a contractor that did not know what they were doing, but these guys put all my worries to rest on the first day.
