Railings and stairs aren’t just safety features — they’re part of your deck’s identity. We help you choose materials, profiles, and layouts that complement your home’s architecture while meeting New Hampshire building codes. Whether you need a wide set of stairs to the backyard, a space-saving stairway to an upper level, or sleek horizontal railings with minimal obstruction, we’ll make it safe, beautiful, and structurally sound.
We custom build every railing and stair system from the ground up — no off-the-shelf kits or weak points. Our stairs are framed with pressure-treated stringers and precise riser spacing for comfortable access. Railings are anchored to meet height and load standards and styled to match your decking. We also install lighting, gates, and accent features where needed. Every build is engineered for years of safe, secure use.
Code-compliant height, load, and spacing
Wood, composite, aluminum, or cable systems
Stair landings, handrails & closed risers

Every deck has a unique view and purpose — and your railings should reflect that. Want a clear line of sight to your backyard? Try cable or glass panel systems. Prefer a more traditional look? We build wood and composite railings with custom baluster spacing, post caps, and trim details. From walkout decks to wraparound porches, we design railings that are as sturdy as they are stylish, all while meeting the unique safety needs of your elevation and site.

The difference in a quality build isn’t just visual — it’s how it feels underfoot. Our stairs are framed with stringers sized for your span, secured with brackets or ledger systems, and built to eliminate bounce or sway. We notch and reinforce rail posts for a tight fit and long-term hold. Whether it's a high deck with multiple landings or a low-profile walkout, we build every stair and railing system to handle real use and New Hampshire’s changing weather.
We offer more than standard railing kits — our builds can include custom baby gates, under-rail lighting, built-in privacy screens, or ADA-compliant handrails. If your deck sits high off the ground or serves older family members, we’ll add features that enhance safety without taking away from your style. Every detail — from stair tread depth to post spacing — is measured, cut, and installed by hand for clean lines and code-ready peace of mind.

Stairs and railings should feel like part of the deck — not an afterthought. That’s why we frame each one based on your home’s elevation, deck footprint, and how you actually move through the space. Whether you're planning for kids, older adults, or guests, our designs offer secure footing, comfortable grip height, and smooth transitions between levels. Built with quality materials and a craftsman’s eye for detail.
Wide or narrow stairs with code-compliant risers
Post-mounted, fascia-mounted, or inset railings
Optional lights, gates, or privacy screens
We don’t cut corners on the details that matter. Our stair stringers are made from pressure-treated lumber or composite framing, with secure anchoring at both ends. Railings are reinforced at all posts and set with hardware rated for wind, moisture, and long-term use. Every part of the system — from first tread to final cap — is built for real-life wear and weather. You’ll feel the difference every time you step outside.
