"Rupert and Michael just completed staining and sealing our very complicated deck/pergola project and did a masterful job. Their communication was prompt, every appointment was on time and their knowledge and craftsmanship was evident from start to finish. We especially appreciated their attention to detail and their care in protecting the surrounding detail of our 1906 home. Our finished deck is beautiful!"

"While they are a little on the pricier end of things, I have to say that I am more than pleased with the power wash, bleach and preserve that the crew did on fence and pergola. When they were done it was like they were brand new! Highly recommended!"

"We were thrilled with the work Ramirez did on our backyard landscaping. The staff were professional, timely, and highly skilled. We especially loved the stamped concrete patio, the elegant paved border, and the lava rocks. They planted over 100 plants and expertly installed our irrigation system. Roberto and his team have been incredibly responsive, even handling additional small tasks like irrigation fixes. We highly recommend their services."

"Victor did an Outstanding job. We wanted a stain on the new fence on 2/3 of our property and were hoping that the last 1/3 could be renewed as well as a Large area of decking around our pool and 2 older decks off the house. He made it all look terrific. His suggestion on the color of the stain with a contrasting trim made it even more beautiful. He and his crew were very efficient and conscientious in their work. I would highly recommend Blue Wave."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

FAQs for deck, fence, patio or porch clean and seal projects in San Jose, CA

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.
