Outdoor Spaces Built to Last Decades

Your backyard should be a place where you actually want to spend time, not a space that sits unused because it lacks the right structure or surface. In Lewistown, outdoor living means dealing with sun, wind, and temperature swings that test every board and fastener. Black Hammer Building designs and builds custom decks, railings, pergolas, and outdoor built-ins that hold up to Montana weather while giving you a functional, comfortable space to gather, cook, and relax.

We work with Trex decking for low-maintenance durability, or cedar and fir for a natural look that ages beautifully over time. Every deck we build includes proper foundation work, level framing, and secure railing systems that meet code and stand firm underfoot. Whether you're adding a new deck to a Lewistown home or building a pergola to shade your patio, you get construction that's built to handle years of use without sagging, splitting, or requiring constant upkeep.

Book your outdoor structure project in Lewistown and start building the yard you've been picturing.

The project begins with site evaluation and design planning, assessing your yard's grade, soil conditions, sun exposure, and views to position your deck or pergola for maximum enjoyment and structural stability. Material selection follows, where you'll weigh Trex's resistance to fading and splintering against cedar's natural aroma and warm tones or fir's structural strength and cost-effectiveness. Each choice affects maintenance needs, lifespan, and the overall character of your outdoor space.

Construction starts with proper foundation work—concrete footings placed below frost line to prevent heaving during Lewistown's freeze-thaw cycles, ensuring your deck remains level and stable year after year. Framing is built to code with appropriate joist spacing and ledger attachment, followed by decking installation with precise gap spacing for drainage and thermal expansion. Railings are installed at comfortable heights with spacing that meets safety standards while maintaining sightlines. Pergolas receive additional bracing to handle wind loads common in open Montana landscapes.

Finishing touches include stairs with comfortable rise-and-run dimensions, integrated planters or benches, and staining or sealing to protect wood surfaces from UV damage and moisture penetration.

Outdoor structures need to do more than look good—they need to support weight, resist moisture, and stay level through freeze-thaw cycles and UV exposure. We use construction techniques and fastening systems that prevent warping, rot, and movement so your deck or pergola stays solid year after year.

Your outdoor space should work as hard as the rest of your home, giving you a place to cook, relax, and entertain without worrying about loose boards or weathered finishes. We build decks and outdoor structures in Lewistown that hold up to heavy use and stay looking sharp season after season. Reach out to us now to schedule services like deck construction.
