Built to Handle Water, Weight, and Montana Weather
Pool Deck & Hot Tub Surrounds in Montana
Safe for Wet Feet. Strong Enough for Full Tubs.
What Makes a Great Pool or Spa Deck?
These aren’t your average decks. Pool and hot tub surrounds need non-slip surfaces, water-safe framing, and support that holds hundreds of gallons of water—plus people. We build decks that meet those demands with reinforced joists, waterproof composites, and ventilation gaps that keep moisture from getting trapped. From freestanding cedar platforms to integrated composite surrounds, we match your setup and Montana’s climate.
Comfort, Drainage, and Strength in Every Build
What We Include in Pool & Spa Surround Projects
Our pool decks and hot tub platforms are fully customized to your space. Whether you need a flush mount around an in-ground pool or a raised deck for an above-ground spa, we design for drainage, comfort, and easy access. We add built-in steps, benches, handrails, or privacy walls depending on your goals. Every project balances slip safety, water flow, and long-term strength.
Framed and reinforced to hold water weight safely
Slip-resistant surfaces that stay cool underfoot
Drainage planning to prevent pooling or water damage
Custom Fit for Any Spa or Pool Setup
Above-Ground, In-Ground, and Built-In Design Options
We build pool and spa decks for all configurations from small backyard hot tubs to full-sized in-ground pools. Our builds can wrap around the entire structure or cover one side for safer access and cleaner aesthetics. Want the tub fully recessed into the deck? We’ll frame and support it properly. Need space for lounging, gear, or a walkway? We’ll work it in. It’s your backyard built your way.
Slip-Resistant and Weather-Tough
Materials Built for Wet Feet and Montana Winters
We use materials that stay grippy when wet, resist fading in UV, and stand up to freezing temperatures. Composite is our most popular choice cooler underfoot than concrete and far lower maintenance than tile or bare wood. For rustic charm, we also offer treated cedar sealed with water-repellent finishes. No matter your choice, every surface we install is safe, sealed, and strong enough for year-round use.
We Engineer for Water Load and Code Compliance
Framing and Fasteners That Keep It Safe
A full spa can weigh over 4,000 pounds that’s why every hot tub surround we build is engineered for load. We use doubled-up joists, extra footings, corrosion-resistant brackets, and ventilation spacers to prevent rot. Whether we’re placing a spa on an existing deck or building a dedicated platform, we build it to Montana code and above industry standard.
