"We hired this company for exterior painting and couldn?t be happier with the results. From the very beginning, communication was clear and professional. They showed up on time, protected all surrounding areas carefully, and paid attention to every detail. The surface preparation was done properly, and the final paint finish looks smooth, clean, and high-quality. The crew worked efficiently and kept the job site organized throughout the project. The house looks brand new again! I would definitely recommend them to anyone looking for reliable and professional exterior painting services. "

"Highly recommended. I would hire them again. Douglas is very knowledgeable. He not only did as promised, but added on work without taking advantage. His crew is excellent as well. Not only did the work how and when promised, but also top-notch quality."

"I highly recommend Hamada Prestige 1 Fine Finishes and Painting LLC for the outstanding work they did on my home in Bend, Oregon. In February 2022, they did an amazing painting job, including custom stain and glaze finishes in my living room. They completely transformed my beams and posts, making them look absolutely beautiful, and my doors turned out fantastic as well. They also painted the entire house and left it looking stunning. What I appreciated most was how clean and organized they were throughout the entire process, along with the exceptional quality of their work. I was so happy with the results that I hired them again in December 2025 to update the look of my dining area. They transformed the previously dull colors on the soffits and beams using their unique technique, giving them a more classic and elegant style. Once again, the results exceeded my expectations. I definitely recommend them and will absolutely use their services again in the future."

"Went very well and better than I could have hoped for. Very impressed with professionalism and responsiveness. Work was done quickly/efficiently. They cleaned up the worksite several times during the day and left things neat/tidy when they left at the end of the day. I plan to hire them again for some work on my deck. I highly recommend this company. P. Johnson Wilsonville, OR"

FAQs for deck, fence, patio or porch clean and seal projects in Portland, OR

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.
