Expert Deck Construction in Helena, MT

Deck construction in Helena means building for a climate that tests every joint, footing, and board. Winters bring heavy snow loads and hard freezes. Summers bring intense sun and dry heat. MWR Construction LLC and Timber Ridge Homes design and build decks that hold up through both. Helena's frost depth runs 42 to 60 inches depending on your neighborhood, and the city's expansive clay soil can shift footings over time if they are not set correctly. We account for those conditions from the first site visit. Our process covers site evaluation, structural framing, decking, railings, and stairs. We build for single-story and multi-level homes across Helena. Whether you want a simple backyard platform or a larger outdoor living area with built-in seating, we size the structure to your property and your goals. If you are ready to add usable outdoor space to your Helena home, contact MWR Construction LLC to talk through your project.

Highly recommend Matt @ MWR Construction. He completed a ICF home for me and could not be happier. I made some changes along the way and he was very accommodating listened to my questions, and his input was very beneficial. Im so grateful for the beautiful home he built for me. Now on to decorating and finishing the interior and landscaping!

We’ve had a great experience with Matt. He is very knowledgeable with all areas of construction. He suggested we use ICF blocks for the shell of our house, and we are really happy we did!
