"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."

"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."

"So very grateful for Kerri Construction’s expertise in redesigning our front yard. Rich Kerri produced a plan with a solution for the hazardous step at our front door, removing the aged lawn and overgrown shrubbery, and was flexible as we finalized plant selections. Once the project started, the crew was exceptional at every stage. Always prompt, courteous and ready for the day’s tasks. So much hard work, and we truly appreciate it! The final product is beyond our expectations. We love the open space the rocks provide, the accent boulders, and lighting. Plants are strategically placed, and bring it all together. We are very happy with the outcome! R & T"

"It was a struggle in the beginning.  The company wanted to charge more when they showed up to do the work.  They said they wanted to charge for fence post holes, something they said was not included in the contract.  We wanted to know why not? This greatly changed the price of the job. The contract had already been signed by our neighbor and me and prepaid (we worked through Home Depot).  We had long discussions back and forth with the people on their end (regional manager, etc.)  We finally told them not to do the job and we will get more estimates.  After all this, they agreed to do the job at their original estimated price.  After this they did a great job. <br />"

"I was impressed by the expert confident knowledge of Neal Golding. I was concerned if out job would be too small and he happily said they do this size job all the time. I had many worries about the balcony floor that had leaked for more than 10 years off and on with 2 composition roofing jobs done to it. Neal suggested replacing the small drain pipe with a scupper to allow more water to flow out and not become clogged. That was a stroke of genius and exactly what would solve my problem with this balcony floor. They did not have to come thru the house to access the balcony which was a relief. The removed all the old composition roofing off the balcony floor and added new subfloor materials to assure an accurate drain slope. They applied a layer of epoxy, then a layer of fiber glass and resin, then after sanding they applied a final coat of colored epoxy. The balcony is as water tight now as a bathtub, finally after 10 years!! These guys did it all in 3 days. I was happy to see they also removed all the wasted materials off to the dump. I am so happy with the results, its professional appearance, and the ease of maintenance it will give. I recommend them to anyone. <br />"

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