"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!"

"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!"

"The crew did a fantastic job of removing moss off our roof tiles and washing our home/property from the roof to the driveways. Very professional and has the proper equipment to get any job done. It's so satisfying to pull up to a nice clean home exterior!! I highly recommend them!!"

"Mr Lopez did a walkthrough and pointed out the loose fence posts and said they needed to be replaced. Gave us price options for 4x4 and 4x6 replacement posts. We went with the 4x6 since we felt they would be able to support the fence portions that were not replaced, and the 4x6 looks fine. When they took out the old fence posts (many of which were put in 3-4 years ago by another company) we could see that some were rotted through, and some of the 7' posts were sunk only 6" into the ground. So we are very glad we replaced them. In all they replaced 21 posts plus the 12' section of fence. The replaced fence and gate look great. Mr. Lopez' crew could replace most posts without going into the neighbors' yards, which was convenient. It took 2-3 days to repair all the fences , and the gate was installed later. He and his crew were polite and professional. There was a minor issue with the gate being too narrow (measuring issue), but they put in a shim to correct for that. It still looks great. We definitely recommend Lopez Fencing."

"Right off the bat I was impressed with getting a call back within 1/2 hour of leaving a message. That in itself was a new experience for me, compared to waiting several days, or longer, or to no call back at all with other contractors. Don himself came the next day and gave me an estimate. He offered ideas and helped me solidify exactly what I wanted. He and his crew were always on time and on schedule. Don was very responsive, either answering right when I called or calling back within a very short time. He made a couple of changes for me that may have seemed a little picky, but he did so with no question and always followed through. If he says he will do something, he does it. They completed the project in only 3 1/2 days, a bit faster than promised and left the area clean of any debris. Price wise, he wasn't the cheapest bid or the most expensive bid, but was right in line with the average going price for such services. I felt comfortable with the price because I felt he knew what he was doing and I appreciated his professional manner. I'm willing to pay for that quality of character, as well as the quality of work. This was one of the most pleasurable experiences I've ever had with a contractor. I am so happy with my deck. It's just beautiful. I wouldn't hesitate to hire his company again and to recommend him to friends and family."

"It went incredibly well. Ignacio spent a lot of time with us working on the design and budget. While this company is not the cheapest on the market, in this case you truly get what you paid for. Ignacio's design took our breath away. The texture and color of the stamped concrete is beautiful. The extra patio space transformed an ugly weird patio to a masterpiece. The flagstone topped retaining walls easily provides seating for more people than we know. The color coordination between the concrete, the flagstone, and the stucco faced retaining walls is very pleasing to the eye. Unique' s crew is one of the best that I have had the pleasure to have working for me. I have never seen a harder working crew. The truly gave us a full 9 hours of back breaking work. The job superb Roberto was fantastic, easy to work with and to communicate. Ignacio made it a point to stop by every day. As with all construction there are issues, broken water lines, sprinkler lines, irrigation control cables. Roberto took immediate care of any and all such issues. He did a great job in keeping my stress levels low. <br /> <br />This may be the best hardscape company in the Bay Area. The attention to detail is exceptional. Ignacio has a designer's eye. <br /> <br />We love the result, and have spent more time outside in the last month than in the three previous years.. <br /> <br />Hire this crew. You will not be disappointed. <br /> <br />Bryan Grady <br />408-309-5363 <br />"

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.
