"I had an outdoor playground set. Adrian was professional and hard-working. Great communication and he brought all the required tools and equipment. He showed up first thing in the morning on a short notice and it was all done before the end of the day. The assembly looks great and I know the kids will love it!"

"Very easy to work with. I'd used them before but this time I got estimates from other contractors and was amazed how much more reasonable Cal Preserving was. The difference may be that the others pointed to additional steps that could be taken. Did Cal Preserving "miss" these things or recognize they weren't necessary--I'm inclined to believe the latter."

"It went incredibly well. Ignacio spent a lot of time with us working on the design and budget. While this company is not the cheapest on the market, in this case you truly get what you paid for. Ignacio's design took our breath away. The texture and color of the stamped concrete is beautiful. The extra patio space transformed an ugly weird patio to a masterpiece. The flagstone topped retaining walls easily provides seating for more people than we know. The color coordination between the concrete, the flagstone, and the stucco faced retaining walls is very pleasing to the eye. Unique' s crew is one of the best that I have had the pleasure to have working for me. I have never seen a harder working crew. The truly gave us a full 9 hours of back breaking work. The job superb Roberto was fantastic, easy to work with and to communicate. Ignacio made it a point to stop by every day. As with all construction there are issues, broken water lines, sprinkler lines, irrigation control cables. Roberto took immediate care of any and all such issues. He did a great job in keeping my stress levels low. <br /> <br />This may be the best hardscape company in the Bay Area. The attention to detail is exceptional. Ignacio has a designer's eye. <br /> <br />We love the result, and have spent more time outside in the last month than in the three previous years.. <br /> <br />Hire this crew. You will not be disappointed. <br /> <br />Bryan Grady <br />408-309-5363 <br />"

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