"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!"

"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!"

"Derek was able to accommodate me with pressure washing a swimming pool that was infested with dirt and algae for over 25 years. He quickly and efficiently brought it back to life. I will be recommending Derek to all of my clients. Job well done!"

"It is nice to find a company like The Painting Pros that stand behind their work. They painted the whole house a little over five years ago but some moisture got in and caused some peeling (typical of wood siding.) I called the company and they immediately sent a representative to check it out. It was beyond the five year warranty but they stood by their work and with no extra charge, they repainted the problem areas and more!! They blended the new and the old and the front looks brand new. They did a great cleanup job with nothing left behind except a well Painted house!! A special thanks to Cleve for coordinating it all and to Salvador who did a beautiful job!!!"

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