"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."

"WOW.
I thought my 30 year old redwood deck wasn't salvageable, but Rupert convinced me to do so.  He was very prompt & reliable & knowledgeable and everything went as planned.    A real pleasure to work with, especially if you prefer texting over e-mails!!
I thought it was going to need replacement, a cost of $20,000 using a wood/plastic composite.  I am glad I didn't spend all that money- I would have had a plastic deck (Trex )that would scratch/warp/stain/turn to plastic-dust ( according to reviews at http://www.consumeraffairs.com/homeowners/trex_composite_decking.html) 
Instead, I have a sturdy splinter free redwood deck and $18,000 still in my pocket.  Environmentally I saved as well, by 'fixing & reusing rather than buying/manufacturing plastics that would end up un-decomposed in a landfill one day.
If you want a facelift on your old deck- Summit Deck Doctors is the way to go.
If you think your deck is dying and needs to be buried & replaced, don't do so without asking Summit Deck Doctors to resuscitate it.

"I had them paint the entire interior of a 3 bedroom 2-1/2 bath home. Proper preparation is important. They were careful and accurate with their masking and protection of surfaces not to be painted, splattered, or over-sprayed. They filled nail holes, nicks, and cracks in the walls and trim and primed old enamel paint. Painting was smooth without thin spots or drips, runs, etc. They started on time and finished quickly on schedule. They left the house clean."

"Fantastic job! I can't believe how bright and clean the deck and the surrounding areas look. It's clear that Blue Wave takes pride in their work and goes the extra step to please the customer. The windows have never looked better. Some are quite hard to reach and have not been cleaned in ages. They look brand new. I'm so happy with the expert and professional service provided by Indira and her team. I will definitely call Blue Wave again."

"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!"

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