Custom Deck Building & Professional Repair in Sioux Falls, SD

Expand Your Living Space with a Precision-Built Deck

In South Dakota, a deck is more than just an outdoor platform—it’s where we spend our best summer evenings and host our favorite weekend barbecues. At Mullen’s RPM, we specialize in designing and constructing custom decks that are built to withstand the Sioux Falls climate. Whether you are looking for a brand-new composite deck or need to restore a weathered wood structure, we bring “RPM” (Remodeling & Property Maintenance) expertise to every joist and plank.

From the high winds of the open prairie to the heavy snow loads of winter, we ensure your deck is engineered for safety, longevity, and style.

Our Decking & Outdoor Structure Services

We serve homeowners in Sioux Falls, Brandon, Canton, Harrisburg, Lennox, Tea, Hartford, and Renner with high-quality outdoor solutions. Our deck services include:

  • Custom Deck Construction: Building new outdoor spaces using cedar, premium pressure-treated lumber, or low-maintenance composite materials like Trex or Timber Tech.

  • Deck Resurfacing: If your “bones” (the frame) are still good, we can save you thousands by simply replacing the old boards and railings with modern, durable materials.

  • Structural Repairs: Fixing sagging joists, wobbly railings, rotted posts, and rotten legs to ensure your deck meets current Sioux Falls safety codes.

  • Stair & Railing Upgrades: Installing modern cable railings, black aluminum, modern or classic spindle systems for improved views and safety.

  • Under-Deck Solutions: Creating dry, functional storage or patio space beneath elevated decks.

  • Power Washing & Restoration: Professional cleaning and sealing to protect wood decks from UV damage and moisture. We also offer painting and staining options.

The Mullen’s RPM Difference: Built for the SD Climate

As a “Remodeling & Property Maintenance” company, we see the mistakes other builders make. We know that in Sioux Falls, the “freeze-thaw” cycle can heave deck posts if they aren’t set correctly. Mitchell Mullen ensures that every footing is dug to the proper depth and every connection is flashed correctly to prevent rot behind your home’s siding.

We don’t just build a deck and disappear; we build it with the maintenance side in mind. We choose fasteners and finishes that handle the South Dakota sun and snow, ensuring your outdoor retreat remains beautiful for years to come without constant repairs.
