"Stuart Riensche and his crew did an excellent job and were a pleasure to work with. I would highly, highly recommend this company to anyone. He runs a tight ship. We were soo impressed with the quality of work! Great attention to detail. Such a beautiful job and done on time, on budget without any negative suprises. Can't say enough good things about these guys. And their pricing was very competitive. Stuart got back to us quickly and once we accepted the bid, he scheduled us. The project start date was a couple of months out, and they started right on schedule. Our home hadn't been painted in 15 years ago and was starting to look like it needed to be done again. My husband had used a sprayer and only put on a single coat at the time. When they pressure washed our house, quite a bit of loose paint came off, down to the bare wood. That meant that the primer paint layer that was needed was more extensive than they had planned. They did a great job making sure the bare wood was all primed, and then painted 2 coats of top quality paint. All the lines are crisp and so professional. We realized after they started that we also wanted to have the deck painted, and they were able to do that too, at a very good price. Stuart and his team met and greatly exceeded our expectations! Really great company."

"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!"

"I had a great experience with Sean, Christian and Melissa🙏. They did not try to upsell me by replacing the whole deck, instead they worked very hard to sand the highly weathered deck and repair it. I am thankful for the work they did at a very reasonable cost. I am very happy with the end results."

Customers say: Quick response

"Mr. Craig was really professional in his approach to this job. It isn't easy to find folks who want to do the smaller handyman jobs and finding him was great. We had an outside door whose trim had rotted and which needed replacing. He came and did up an estimate for us in a very prompt fashion. We were able to reuse the existing exterior solid wood door, which was in great shape - that was very helpful and cost efficient. He was good about keeping us in the loop on timing and did a good, thorough and very professional job on the door. I would definitely recommend him to others and use him again."

"We had Volcano Builders refresh our condo bathroom and flooring. Bar was punctual, polite, and answered all our questions. They protected our home?using drop cloths, containing dust, and cleaning nightly. Work was finished earlier than the estimate and with exceptional quality. It feels like a brand-new condo. Would definitely recommend them for condo renovations."

"I could not be more pleased with Joseph and the work he performed. I needed an existing patio to be replaced due to tree roots which impacted drainage towards the house foundation. After 5 bids, I decided to go with Joseph due to his competitive bid and demonstrated expertise. He and his team were stellar, solid communication, friendly, and took the time to explain to me the leveling/answering all my questions. In 3 short days the project was completed and it looks great. I would highly recommend Joseph to anyone looking for concrete work."

"This is the second time I have used this service, and even though I was happy first time, I was even more impressed this time. My large garden was overrun with weeds and ivy. After 2 men worked 4 hours, I was left with a renewed garden that was beyond my expectations."

FAQs for deck, fence, patio or porch clean and seal projects in Duvall, 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.
