"CalPreserving was the total deal! I didn't know what all we needed and all the serves Iooked at seemed to offer only a piece of the puzzle, such as just power washing, or construction, or staining. This group did it all. The initial visit to assess the issues was informative and helpful. We could see our choices. They offered sound advice and looked at ways to save us money where it was possible. We ended up replacing about half the boards on the oldest deck. The finished product on both decks looks amazing -- like new. The workmen were thoughtful, knowledgeable, hard working, and polite. I was impressed that they even followed up with tips on maintaining the decks for years to come. I will definitely have them back every couple of years just to check on the decks and preserve the investments we have made in them. My highest recommendation."

"Our large deck was sorely neglected - no maintenance in at least 8 years - and I worried it was beyond help or would be cost-prohibitive to rehabilitate. Rupert and Michael breathed new life into it! Rupert (company principle) is very responsive, and he was able to give a quick informal estimate based on some photos and I texted. This made it very easy to start working together right away. Now the deck looks beautiful, and they were able to stain our wooden deck furniture to match. Great makeover for our deck and lovely folks to work with!"

"This company is the very best. My two old decks now look like they are new. The crew is very detail-oriented especially with the prep workâ -power washing and sanding â so the final staining is perfect. My windows were covered while they worked and everything cleaned up when they finished. Also, the price was very reasonable. I definitely recommend them!"

"These guys were great! We moved into a house and needed help understanding why our landscaping quickly started dying. Landscaping Bay Area carefully diagnosed and quickly fixed the issues, thoughtfully taught us about our system, and added lines to automate our yard care. Would absolutely recommend and use them again!"

"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!"

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