Give New Life to an Aging Deck

Deck Restoration & Refinishing in Wisconsin

No Need to Replace What Can Be Restored

Smart Restoration Solutions for Aging Decks

Refinishing is often the fastest and most affordable way to extend your deck’s life. If the structure is sound, our team can remove old coatings, clean off mildew and debris, sand rough surfaces, and reapply high-performance sealants or stains. We assess every deck carefully to ensure it’s a good candidate for restoration—and we’ll always be honest if repairs or upgrades are needed. Most decks show dramatic improvement with just one day of hands-on restoration.

Complete Restoration, Start to Finish

Clean, Sand, Seal—and Make It Look New Again

Our process starts with a detailed deck inspection. Then we power wash away dirt, algae, and grime. Next, we sand any splintered or rough areas and remove failed coatings. Once prepped, we apply durable stains or sealants designed for Wisconsin’s climate—restoring color and protecting your wood from moisture, mold, and UV rays. We’ll help you choose a finish that complements your home and enhances your outdoor space.

Sealants and Stains That Stand Up to the Seasons

Wisconsin decks face moisture, snow, sun, and wide temperature swings—all of which wear down protective coatings and damage wood. That’s why we only use premium-grade stains and sealants rated for harsh Midwest conditions. Whether it’s a rich cedar tone or a transparent finish that showcases the grain, we’ll recommend products that hold color, resist peeling, and keep moisture out. With the right prep and materials, a refinished deck can look great and stay strong for years.

Prevent Bigger Problems with Timely Maintenance

Neglected decks don’t just fade—they crack, rot, and weaken structurally. Refinishing now can prevent costly repairs down the road. We often find hidden damage during the cleaning and sanding process—issues like soft spots, split boards, or loose railings. When caught early, these problems are easy and affordable to fix. Alliance Deck Builders helps you stay ahead of the damage, protecting your investment and keeping your deck safe for the long haul.

We Refinish All Types of Wood Decks

From soft cedar to dense pressure-treated lumber, each type of wood needs different prep and products. Our team knows how to treat each surface correctly—adjusting sandpaper grits, cleaning techniques, and stain types based on your deck’s material. We also provide light touch-ups for composite surfaces, including cleaning and UV sealant application. Whether your deck is one year old or twenty, we’ll restore its beauty without compromising the wood.
