We know the best products for our local climate, and we prepare every surface properly so the finish goes on smooth and lasts as long as possible.
Why Deck Finishing Protects Your Investment
Many homeowners think staining or sealing is just about looks. But it is really about protection. A good finish creates a barrier between your wood and everything that wants to damage it. Here is what a quality stain, sealer, or paint does for your deck:
- •Blocks moisture: Water is the biggest enemy of wood decks, causing rot, mold, and warping
- •Shields from UV rays: Sunlight breaks down wood fibers, causing fading and surface damage
- •Prevents cracking and splitting: Temperature changes make wood expand and contract, leading to cracks
- •Stops mildew growth: Many finishes include mildewcides that prevent mold and algae
- •Extends deck lifespan: Regular finishing can double or triple the life of your deck
- •Enhances appearance: Fresh stain or paint makes your deck look brand new
Choosing Between Stain, Sealer, and Paint
Not sure which finish is right for your deck? Each option has different benefits and ideal uses. Here is how they compare:
Deck Stain
Stain penetrates into the wood and enhances the natural grain. It comes in transparent, semi-transparent, and solid colors. Transparent stains let the wood grain show through completely. Semi-transparent stains add color while still showing the grain. Solid stains cover the grain like paint but are thinner and more flexible. Stain typically lasts two to three years before needing reapplication.
Deck Sealer
Sealer provides a clear protective coating without changing the color of your wood. It blocks moisture and UV rays but lets the natural wood color and grain shine through. Clear sealers are great for new decks or decks made from beautiful woods like cedar or redwood. Sealers need reapplication every one to two years.
Deck Paint
Paint creates a solid, opaque coating that completely covers the wood. It offers the most protection and the longest lifespan, often lasting four to six years. Paint is a good choice for older decks with imperfections you want to hide. It also gives you unlimited color options. The downside is that paint hides the wood grain and requires more prep work.
We help you choose the right finish based on your deck's age, wood type, and your aesthetic preferences. For decks needing structural work before finishing, check out our deck repair services.
Our Professional Finishing Process
The key to a long-lasting finish is proper preparation. We never skip steps or rush the job. Here is how we approach every deck staining, sealing, or painting project in Pittsburg:
Step 1: Cleaning and Prep: We start by thoroughly cleaning your deck. We remove dirt, mildew, old finish, and any debris. For decks with old stain or paint, we use strippers and sanders to get down to bare wood. Clean, dry wood is essential for good adhesion.
Step 2: Repairs: We check for loose boards, popped nails, or other issues that need fixing before we apply the finish. We replace damaged boards and tighten any loose fasteners. This ensures your deck is structurally sound before we seal it up.
Step 3: Drying Time: Wood must be completely dry before we apply any finish. We check the moisture content with a meter to make sure the wood is ready. Applying finish to damp wood leads to poor adhesion and peeling.
Step 4: Application: We apply stain, sealer, or paint using brushes, rollers, or sprayers, depending on the product and deck condition. We make sure coverage is even and thorough, paying special attention to end cuts and joints where moisture can enter.
Step 5: Drying and Curing: We let the finish dry completely before you use your deck. This can take 24 to 48 hours depending on the weather. Some products need multiple coats for full protection. For new deck installations with professional finishing included, visit our wood deck installation page.
How Often Should You Refinish Your Deck?
The lifespan of your deck finish depends on several factors: the product you use, the weather exposure, and how much traffic your deck gets. Here are some general guidelines for Pittsburg homeowners:
Clear sealers need reapplication every one to two years. They offer the least protection but let the natural wood show. Semi-transparent stains last two to three years. Solid stains can last three to four years. Paint lasts the longest, often four to six years before needing a fresh coat.
Here is an easy test: pour some water on your deck. If it beads up, your finish is still working. If the water soaks in, it is time to reseal. You should also look for signs of wear like fading, peeling, or rough spots. Catching these early makes refinishing easier.
Regular cleaning extends the life of your finish. Sweep your deck regularly and wash it once or twice a year with a deck cleaner. Avoid harsh chemicals or power washers on high settings, as these can damage the finish and the wood. For ongoing maintenance and care, explore our full range of deck services.
