Save Your Deck and Protect Your Investment

Is your deck showing its age? In the harsh South Dakota climate, wood and composite decks are under constant attack from heavy snow, UV rays, and extreme temperature swings. At Mullen’s RPM, we specialize in professional deck repair and structural restoration. Many homeowners think a weathered or “wobbly” deck needs a full replacement, but often, a expert repair can add years of life to your outdoor space at a fraction of the cost.

Whether it’s replacing rotted boards, securing loose railings, or fixing structural “sway,” Mitchell Mullen provides the technical “RPM” (Remodeling & Property Maintenance) expertise to make your deck safe and beautiful once again.

Comprehensive Deck Repair Services

We help homeowners in Sioux Falls, Brandon, Canton, Harrisburg, Lennox, Tea, Hartford, Renner, Lincoln County, and Minnehaha County address the most common and dangerous deck issues, including:

  • Structural Joist & Post Repair: Replacing rotted support posts or “sistering” joists to fix sagging areas and ensure the deck can handle snow loads.

  • Stair Replacement: Old, worn out, or poorly built steps can be a major safety issue. Consider the piece of mind that comes with repairing or replacing them completely.

  • Board Replacement: Swapping out splintered, cupped, or rotted cedar and pressure-treated boards with a seamless match.

  • Railing & Stair Safety: Tightening or replacing wobbly handrails and rebuilding stairs to meet current Sioux Falls safety codes.

  • Deck Leveling & Leg Replacement: Addressing piers that have shifted due to the South Dakota freeze-thaw cycle. As well as replacing legs that are old, rotten, or installed incorrectly.

  • Hardware Upgrades: Replacing rusted bolts and nails with modern, corrosion-resistant structural screws and hidden fasteners.

  • Power Washing & Re-Staining: Stripping away gray, weathered fibers and applying professional-grade sealants to prevent further water damage.

Why Choose Mullen’s RPM for Your Deck Restoration?

Deck repair is a specialized skill. Unlike a general handyman who might just put a “Band-Aid” on a problem, our team looks at the structural integrity of the entire system. Because we understand property maintenance, we identify why your deck is failing—whether it’s improper flashing against your house or poor drainage underneath—and fix the root cause.

We are a local Sioux Falls company that values honesty. If your deck is truly beyond repair, we’ll tell you upfront. But if it can be saved, we use the highest quality materials to ensure our repairs stand up to the wind and ice of the Great Plains.
