"CalPreserving was the total deal! I didn't know what all we needed and all the serves Iooked at seemed to offer only a piece of the puzzle, such as just power washing, or construction, or staining. This group did it all. The initial visit to assess the issues was informative and helpful. We could see our choices. They offered sound advice and looked at ways to save us money where it was possible. We ended up replacing about half the boards on the oldest deck. The finished product on both decks looks amazing -- like new. The workmen were thoughtful, knowledgeable, hard working, and polite. I was impressed that they even followed up with tips on maintaining the decks for years to come. I will definitely have them back every couple of years just to check on the decks and preserve the investments we have made in them. My highest recommendation."

"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."

"After replacing our wooden deck we need to have the deck sealed. Platinum responded promptly. They provided options and cost estimates for different products to treat the deck. We received a written estimate the same day, the following day they powered washed the deck. Living in a coastal area the morning scheduled to treat the deck was damp. Platinum came back late in the afternoon to allow the wood to dry. The job was completed on time within budget. After the worksite was clean and the deck was beautiful. I would hire Platinum for other painting jobs, we highly recommend them."

"Victor did an Outstanding job. We wanted a stain on the new fence on 2/3 of our property and were hoping that the last 1/3 could be renewed as well as a Large area of decking around our pool and 2 older decks off the house. He made it all look terrific. His suggestion on the color of the stain with a contrasting trim made it even more beautiful. He and his crew were very efficient and conscientious in their work. I would highly recommend Blue Wave."

"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!"

"The approximate cost was $1300. The guys were nice. But the paint job isn't holding up that well. From the wall were my alarm is when the wall gets touch the paint is coming off. I don't think they did do a primer. It's not holding up I can see were it needs to be touched up in hallway and the laundry room where they painted and same in the kitchen. They were kind of in a hurry so they didn't spend time on prep. That's the kind of comment I will make to future customer. It looks good but they don't do a lot of prep. There were areas that have to be touched up.  It's not even a full year yet. They kind of want to get in and out.  Initially he came in with a price. He verbally gave me quotes for each room and because I am a female. He went outside to his truck to come back with the final bill and it was 3 times than what he said for each room. I say to him I guess I have to give you a not so great review on Angie's List because the quote and the integrity of all that is part of why I use Angie's List. When I said that he called me back and said oh I'm so sorry I don't know what I was thinking. That wasn't the quote I wanted to give you. I am like oh my god if I hadn't said that this guy will be taking me to the cleaners. They were on time. They were professional."

"DJ's recommended a color scheme and painted the exterior of our house. They weren't the lowest or highest quote, but they did an excellent job, went out of their way to please, great/friendly/nice crew and I would highly recommend them. They also spent a lot of time on the prep work on a 30 year old stucco house."

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