"They started each day at 8:00 AM and worked until 5:00 or later. They were very polite and professional. The lead person George would explain what they would be doing each day and then perform the tasks. The deck looks like it is brand new and the redwood has the original color and grain. Note: the bill included 4 hours of setting the deck screws so they could sand. Otherwise they performed to the bid."

"While they are a little on the pricier end of things, I have to say that I am more than pleased with the power wash, bleach and preserve that the crew did on fence and pergola. When they were done it was like they were brand new! Highly recommended!"

"Diego and his team were very efficient and helpful with advice and willingness to include some deck repair with the washing, sanding and sealing of our 2 large backyard decks and deck bench. They did all sanding by hand (no large sanders) and painted on all stain and seal by hand. They did the work quickly and were very responsive to requests as needed as the job proceeded. The price was about 20% lower than other bids, and the personal attention to the work was really appreciated. I highly recommend and we will use them for ongoing maintenance of our decks and bench."

"We have used Enrique, Uber and their crew for two projects now and have been very pleased with the results. Their work is excellent, they work quickly, they are polite, listen closely to any concerns you have or changes you feel are necessary. I had one call back for a railing that was not quite what I wanted and they were happy to revise it as I wished. I will definitely be hiring them again in the future."

"Rich and his crew were fantastic. They went above and beyond in many areas, and were always terrific with communication about all of the aspects of the project. They fully landscaped our front yard, including abundant lighting, and replaced the sprinkler system throughout the property. They were a pleasure to work with and the end product is the envy of the neighborhood."

"I bought the deal for $300/painter for the whole day. I met with one guy who came out to see what I wanted to have painted. He was very professional and nice. I wanted the double closet doors painted white, touch up in the kitchen & bedroom, baseboards & trim around a small patio door. He said that all the baseboards would not likely be completed in the timeframe, which was fine with me. The painter, another gentleman, came out a few days later. Long story short, he did a nice job painting but only completed the closet doors & a few touch up areas in the bedroom. If I'd known it would take 6 hrs to paint closet doors, I would've told him to spray them. The original guy, I think he was the owner, never followed up to see how things went. This was a huge waste of $$. <br />"

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