"Cal Preserving did a great job on our very difficult to install Ipe (Brazilian Walnut) deck. I would definitely use them again."

"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!"

"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!"

"The owner initially came to my home to assess the work I needed to have done. He is very knowledgeable about landscaping. The time he spent upfront was greatly appreciated as he fully understood to my landscaping needs. He had great ideas on how to replant a tree, recommend how to control grubs and how to properly care for specific plants. Once the project began the owner was no longer involved. In fact, I never saw him again. In addition to his landscaping services I had him give me a bid for painting my new fence and yard fence. The painting itself was very nicely done however, the worker(s) were careless and left several oil based paint spots damaging 15-20 of my brand new pavers. When I addressed this with The Owner he replied via email his worker(s) told him they didn’t do it. I provided pictures of the pavers as proof to substantiate my claim. The Owner had his lead come by our home to fix a sprinkler head that was covered during sod repair and to remove these stains. When I reached out to The Owner again he solely relied upon his lead who promptly told him the oil based paint stains were removed. The stains still remain, I’ve contacted my pavers company who clearly stated “oil based paint cannot be removed!” It became blatantly obvious the owner was siding with employee. In fact, The Owner not once has stepped foot on my property since he took the bid. He never came to oversee the project and all contact with him has been via email or text. Lastly, we were in agreement to plant a new tree. As of this review, I have never heard back and there was never any follow up as to when this would be done. I really had high hopes In the beginning and I am very disappointed in The Owner’s project management. He appears to be knowledgeable but my recommendation is that he needs to manage his team, stay closer to the project and make an attempt to do a final walk through. Lastly his hourly bill rate was inconsistent vs. negotiated. Hourly rate doubled for final day of painting which I regretfully paid."

"I had them paint the entire interior of a 3 bedroom 2-1/2 bath home. Proper preparation is important. They were careful and accurate with their masking and protection of surfaces not to be painted, splattered, or over-sprayed. They filled nail holes, nicks, and cracks in the walls and trim and primed old enamel paint. Painting was smooth without thin spots or drips, runs, etc. They started on time and finished quickly on schedule. They left the house clean."

"Ramirez Landscaping and Concrete is very reasonable. Aside from the price, it's the quality of services rendered for our home. Owner has always provided excellent service and care to our property and has even gone above and beyond when needed. What I am most grateful for is the honesty in the work; when damages occur or repairs are needed they are quick to respond. Pricing is very fair and worth the services provided by them. We have been with them for about 6 years now."

"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 Cupertino, 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.
