Welcome to Great Falls Deck & Carpentry

At Great Falls Deck & Carpentry, we’re a licensed, insured, and certified deck builder in Great Falls, Montana with 20+ years of experience. Backed by 5-star Google reviews, we specialize in Trex composite decks, custom wood decks, porches and carpentry projects built to last through Montana’s tough weather. Homeowners choose us for quality craftsmanship, honest pricing, and reliable service.

Most deck projects in Great Falls take about 1 to 3 weeks, depending on the size, design, and materials used.  We always provide a clear timeline with your estimate so you’ll know exactly what to expect.

In most cases, small decks under 30 inches high and not attached to the house do not require a permit in Great Falls. For larger decks or projects where a permit is required, we handle everything for you — from filing the paperwork and drawing the permit to scheduling inspections. Our goal is to make the process as simple and stress-free as possible for you.

We offer multiple levels of Trex composite decking—from Trex Enhance Basics for entry-level builds to Trex Enhance Naturals for premium composite projects—along with pressure-treated and color-treated wood options that provide long-lasting protection without the need for staining. We can include pricing for several material choices in your bid.

Every project is custom-bid, with final pricing based on the materials you choose, the size of the deck, project complexity, and site conditions. This ensures you know exactly what your investment will be before construction begins.
