The Right Way To Clean Your Deck for Spring
Spring is well on its way here in the Pacific Northwest. Beautiful warm days are right around the corner - and that means hanging outside. If your deck has suffered from a bit of winter neglect, it might be time for a spring cleaning.
Gibson Fence and Deck, a local high-end deck contractor in Seattle, made an updated checklist for deck maintenance in 2025.
The first step in deck maintenance is a good inspection. Catching problems early can prevent costly repairs down the road. Check for soft spots, cracks, or warped boards, especially in high-traffic areas. Railings should be secure, and fasteners should sit flush with the wood. If anything wobbles or feels loose, it’s time for repairs. Moisture is a deck’s biggest enemy, so watch for discoloration, mildew, or pooled water—these signs indicate drainage issues or worn-out sealant. Areas with faded or peeling finishes will need extra care during cleaning and sealing.
Once the deck is in good shape, a thorough cleaning protects its structure and appearance.
Dirt, mold, and moisture buildup can lead to rot, fading, and long-term damage. Removing debris and scrubbing the surface prevents deterioration while preparing the wood for sealing or staining. Whether your deck is wood or composite, using the right cleaning techniques keeps it looking fresh and strong for years.
Step-by-Step Deck Cleaning Checklist
✔ Sweep away dirt, leaves, and debris to prevent moisture buildup
✔ Choose a deck-safe cleaner or make a DIY solution with warm water, vinegar, and mild soap
✔ Scrub the surface with a soft brush, following the wood grain
✔ Avoid high-pressure washing on wood decks to prevent damage
✔ Rinse thoroughly and allow the deck to dry completely before sealing or staining
✔ Repeat the cleaning process if stains or discoloration remain
How to Seal Your Deck Properly
You must ensure your deck is clean and dry before sealing it. Sealing adds a layer of defense against sun, rain, and foot traffic. Wood decks absorb moisture without it, leading to cracks, warping, and mold growth. Even composite decks benefit from periodic sealing to prevent fading and surface wear. Choosing the right product depends on your deck’s material and the level of protection needed. A high-quality sealant or stain enhances the wood’s natural beauty while repelling water and UV rays.
✔ Pick a sealant or stain suited for your deck type (wood or composite)
✔ Check the weather—apply only when temperatures are mild and rain isn’t expected
✔ Use a brush, roller, or sprayer to apply an even coat
✔ Allow full drying time before placing furniture or using the deck
✔ Reapply sealant every 1–3 years, depending on exposure and wear
