"I had an outdoor playground set. Adrian was professional and hard-working. Great communication and he brought all the required tools and equipment. He showed up first thing in the morning on a short notice and it was all done before the end of the day. The assembly looks great and I know the kids will love it!"

"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!"

"Bill and the rest of the Fine Point team were incredible.
They sanded and repainted a large kitchen with stained oak cabinets. Since the oak didn't take the paint like other woods, they applied an extra coat of primer and and extra finishing coat to make sure that it looked the way we hoped. They used a spray, which helped give the cabinets a professional, uniform coat. They look fantastic.
When the paint dried, some of the cabinets didn't close properly. This is not a criticism?when we told Bill, he came by the next day to fix those that were misaligned (which could have happened in any project), so the final kitchen looked perfect.
The whole team was really friendly. They put in extra hours to make sure the job was done well, and honored their initial estimate, which was completely reasonably compared to some estimates we received.
They touched up several areas of the house. When we couldn't find a matching paint for the upstairs bathroom, Bill repainted the entire wall with another paint, and he did it for a nominal fee.
What can I say? The team was patient with us as clients, thorough with the job, and masters of the craft. Our house looks fantastic, and I'd hire them or recommend them in a heartbeat.

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.
