"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.

"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."

"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."

"Excellent. Bob picked up the paint from the paint store that we recommended. He draped everything with new drop cloths and was very meticulous in cleaning up. When we did a walk through and noticed some areas that needed cleaning, he was quick to address the issues."

Deck Cleaning FAQs, answered by experts

Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

There are ways to clean your deck to help maintain a clean appearance. You can easily remove surface-level dirt and grime by wetting your deck with a hose and doing a quick scrub with store-bought deck cleaner monthly. 

However, investing in professional deck cleaning services near you at least twice a year is worth it. This service saves you time and ensures that your deck will avoid accidentally becoming scratched by blasting the pressure washer at the wrong angle.

Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.

Finding a reputable deck builder should start with speaking with a local company and asking for samples of past work and references. You can review the company’s workmanship and speak with past customers to learn what the customer service was like throughout the process. It’s also a good idea to read online reviews and check the Better Business Bureau (BBB) website to see if the company has a history of customer complaints. If you can get a referral from a family member or friend, that’s another great option.

Two coats of stain are ideal for the best protection and aesthetic appeal. However, if your decking is made of particularly dense hardwood, you may only need one coat. If you want an intense color, two coats are ideal.
