"I found Alex exceptionally careful and thorough. His pricing was fair. His work ethic was great. He cleaned our deck with a pressure washer. Because of his great job, we hired him to stain our deck. Great choice!"

"These guys are stellar. My deck was in disrepair and I was uncertain what to do with it - whether to totally knock it down and start anew, or to build on the existing foundation. Also what material to use - composite, wood, etc. They came out, looked at my deck, gave recommendations, and worked within my budget. We went with cedar, and within two weeks, I had an absolutely beautiful new deck, built on the existing foundation. I was very pleased with the whole interaction - they were courteous and professional, friendly and hard-working, arriving early and working through the day to get the job done. It was for me an exceedingly good experience with a contractor, and their work is solid. I was nervous as a first time home owner to hire a contractor, for fear of not knowing enough and being taken. I had spoken with several other general contractors and also specific deck builders prior to hiring Modern Exteriors, and each could have built a deck. One larger company offered a lower price but when they came out, the materials they suggested would have been sub-par and the deck would have been plastic-looking. These guys are a smaller business that build decks for a living, and are very good at it and clearly enjoy each project - like works of art. I highly recommend them."

"Peter did a wonderful job on the painting project for our dormer. He scrapped and sanded the siding so when it is now finally finished it looks super. Just like new. He left the job site clean and tidy each day before he left. I would recommend him to anyone that wants a fabulous job. It is well worth and price for the work that he does."

FAQs for deck, fence, patio or porch clean and seal projects in Seattle, WA

You should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.
