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

"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."

"My gutters were blocked and water was causing my door to swell so we couldn’t open it. It was supposed to rain the next day. They came out within 2 hours, fixed it and let me know that my gutters weren’t angled right. Very professional and the price was very reasonable."

"Mr Lopez did a walkthrough and pointed out the loose fence posts and said they needed to be replaced. Gave us price options for 4x4 and 4x6 replacement posts. We went with the 4x6 since we felt they would be able to support the fence portions that were not replaced, and the 4x6 looks fine. When they took out the old fence posts (many of which were put in 3-4 years ago by another company) we could see that some were rotted through, and some of the 7' posts were sunk only 6" into the ground. So we are very glad we replaced them. In all they replaced 21 posts plus the 12' section of fence. The replaced fence and gate look great. Mr. Lopez' crew could replace most posts without going into the neighbors' yards, which was convenient. It took 2-3 days to repair all the fences , and the gate was installed later. He and his crew were polite and professional. There was a minor issue with the gate being too narrow (measuring issue), but they put in a shim to correct for that. It still looks great. We definitely recommend Lopez Fencing."

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