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

"Color Rush Painting gave us a reasonable estimate with a payout schedule. They agreed to a date and time. They were there on time everyday and the work was professionally done. Diego was generous with advice when we asked and we are very happy with their work! We recommend them for any one, with interior or exterior painting needs. . We had both, which included sanding and staining a sadly worn deck. It looks beautiful now!"

"Live Oak works fast and provided great craftsmanship while building a 600 sqft backyard deck with professionalism! They also were agreeable and provided a couple of small extra maintenance services which we didn’t spec out prior to the work being done (touch-up house paint and installation of two foundation vent screens, all under the deck). They did a super job building a very solid structure with great craftsmanship! They provided detailed plans and a bill of materials prior to starting the project. They (Enrique) were great communicators were very thoughtful as to where and when the building materials would be dropped. They also left the yard clean after each days work! They poured foundation posts, built a very solid framing structure with steps in two locations, and laid the finishing planks down with percussion while offsetting connecting seams so they don’t catch the eye. The deck was raised and the finished deck sits perfectly flush with our exterior doors leading out to the deck. The deck also required two doors from the deck surface to access under-deck electrical and drainage items. Those were also built perfectly and unnoticeable unless you’re looking for them. Live Oak is detail oriented and I’d like to thank them for taking pride in their work! There’s nothing better than receiving compliments about our deck from visitors to our home. Thank you! Not only would I hire them again but I would STRONGLY recommend them to anyone needing their services. We feel VERY lucky to have found them!"

"Rich met with us and thru email we finalized the plans. He sent an excellent team of workers out to do the job (Dave, Carlos, Frank & Don). They were all very considerate and helpful. They asked questions throughout the job to verify the finer details and to make sure our needs were met. They worked in mud and rain, so they hosed down the patio and all the walkways every day before leaving. The end product was well done, and everything was cleaned up when they left. Great Team! Thank You. Now the planting begins."

"I remember the first time I met Toby (owner) when he came to our home for a quote. He struck me as someone I could trust with our project. He is super friendly, professional and of high integrity. My many years working with Woodiwiss has only reinforced that view. And his whole team is top notch from the crew in the field to Todd in the office. Without exception, they have exceeded our expectations. They pay attention to the details, see the project through to completion and always clean up in a very professional manner. Toby and Woodiwiss deliver high quality and value. I would highly recommend them to anyone and will continue to use them on our projects!!"

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