What is Our Professional Deck Refinishing Process?

We believe that a lasting finish is 90% preparation and 10% application.

1

Deep Cleaning

We use professional-grade cleaners to remove dirt, gray wood fibers, and organic growth without damaging the wood grain.

2

Specialized Sanding

Once dry, we lightly sand the surface to open the wood pores and remove any remaining imperfections. This step is crucial for even stain absorption.

3

Premium Application

We apply top-tier, contractor-grade stains using a combination of brushing and rolling techniques to ensure deep penetration and a streak-free finish.

4

Final Quality Check

We inspect every board and railing to ensure the coating is uniform and the wood is fully saturated for maximum protection.

CUSTOMER TESTIMONIALS

Customers about our trusted deck repair services

Huge shoutout to Derrick and the crew at Alexandria Builders. Our deck was peeling badly from a DIY job we did a few years ago. They stripped it down completely and applied a beautiful semi-transparent stain that looks incredible. They are clearly experts in deck refinishing and didn't cut any corners on the prep work. If you want your deck done right the first time, give these guys a call.

Alexandria Builders did a fantastic job on our large multi-level deck. Anar was professional from start to finish and made sure we were happy with the stain color before they did the whole thing. You can tell these guys know the Washington climate because they knew exactly when to time the application between rain clouds. Professional, fast, and high-quality results. Five stars for the whole team!

We had a great experience with Alexandria Builders for our deck restaining. Derrick was our main point of contact and he really took the time to explain the difference between the oil and water-based options for our specific sun exposure. The crew was hardworking and respectful of our property. Our outdoor space looks amazing now, and the price was very fair for the quality of work provided.

It’s hard to find reliable contractors in Seattle, but Alexandria Builders exceeded expectations. Anar and his team refinished our mahogany deck last month. They were very careful with our landscaping and cleaned up every night before leaving. The deck has survived several heavy downpours already and the water is still beading up perfectly. I’ll definitely be using them for maintenance in the future.

I’m really impressed with the professionalism of Alexandria Builders. Derrick handled our project and he was extremely meticulous with the power washing and sanding phases, which made a huge difference in the final look. They used a high-quality penetrating oil that really brought the wood grain back to life. Great communication throughout the process and they finished right on schedule.

Our cedar deck was looking pretty grey and weathered after the last two winters. We called Alexandria Builders, and Anar came out to give us an estimate. He was very knowledgeable about which stains hold up best against the Seattle rain. The crew was punctual, masked off the siding perfectly, and the finish is flawless. It looks like a brand-new deck. Highly recommend them for any refinishing work!

Why is Professional Deck Staining Essential for Washington Homes?

Deck staining and sealing are essential to protect your wood from Seattle’s rain and UV rays. Most modern professional stains are all-in-one formulas, meaning the sealer is already built-in to simplify maintenance and maximize protection.

To ensure a long-lasting finish that won’t peel, we select the product based on two key factors:

  • Oil-Based vs. Water-Based: Oil penetrates deep to condition wood fibers, while water-based options offer excellent durability and mold resistance in our damp climate.
  • Film-Forming vs. Penetrating: We choose between products that sit on top (film) or soak in (non-film) to prevent the wood from rotting or cracking.

Properly selected products keep your deck looking fresh and structurally sound year-round.

FAQ

Everything you need to know about deck refinishing

How often should I stain my deck?

Most decks should be stained every 2–3 years, depending on the type of wood, weather exposure, and the quality of previous stain. If your deck looks faded, absorbs water easily, or feels rough, it’s likely time to re-stain.

Do I need to clean or sand my deck before staining?

Yes, proper preparation is key for long-lasting results. We start by pressure washing the deck to remove dirt, mildew, and old finish. If needed, we also sand the surface to ensure the new stain goes on smoothly and evenly.

How long does deck staining take?

Most deck staining projects take 1–3 days, depending on the deck size and the weather. We allow time for cleaning, drying, and applying the stain in optimal conditions to ensure a durable finish.

What kind of stain do you use?

We use high-quality, professional-grade stains that are designed for durability and weather resistance. You can choose from a range of finishes and colors to match your style and protect your wood.

How much does deck staining cost?

Our pricing starts at $6 per square foot for staining. The final cost depends on the size of your deck and any additional services like washing, sanding, or board replacement. We provide clear, upfront estimates with no hidden fees.

When is the best time to stain my deck?

The best time to stain is during dry, mild weather usually spring through early fall. Staining requires the wood to be dry and temperatures to stay between 50–90°F. We always check the forecast to ensure ideal conditions before we begin.
