"Our large deck was sorely neglected - no maintenance in at least 8 years - and I worried it was beyond help or would be cost-prohibitive to rehabilitate. Rupert and Michael breathed new life into it! Rupert (company principle) is very responsive, and he was able to give a quick informal estimate based on some photos and I texted. This made it very easy to start working together right away. Now the deck looks beautiful, and they were able to stain our wooden deck furniture to match. Great makeover for our deck and lovely folks to work with!"

"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!"

"I spent $190 on that work. They were efficient in terms of the e-mails and estimate. The price was reasonable and the quality was of the workmanship was good. The customer service guy was very pleasant when he came to do the site inspection prior to giving the estimate. He answered all my questions during the walk through and provided good customer service. The work was performed to my satisfaction and I probably will use them again. In terms of the work was the price was excellent."

"I was impressed by David's knowledge in our first meeting when he surveyed the house exterior to gather information needed for his quotation. As the painting preparation progressed, it became obvious that I need repairs due to water damages and termites. David took care of all the repair work and worked closely with me and Terminix to treat the termite infestation before completing the painting of the wood siding of one of my second story rooms. David was very accomondating and helpful in offering solutions and implementing them. David helped me to create a water barrier solution eliminating water damages at the bottoms of two posts supporting the second floor structrure and the bottoms of the wood sidings of my storage shed. David was patient listening to my questions and suggestions to obtain the best solution to my problem. My next door neighbor also hired David to paint his house and repaired the termite-damaged patio cover. I am very satisfied with his work and he is my "go-to" painter for my exterior surfaces of my house."

"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.

"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 Alviso, 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.
