"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!"

"This company is the very best. My two old decks now look like they are new. The crew is very detail-oriented especially with the prep workâ -power washing and sanding â so the final staining is perfect. My windows were covered while they worked and everything cleaned up when they finished. Also, the price was very reasonable. I definitely recommend them!"

"The owner initially came to my home to assess the work I needed to have done. He is very knowledgeable about landscaping. The time he spent upfront was greatly appreciated as he fully understood to my landscaping needs. He had great ideas on how to replant a tree, recommend how to control grubs and how to properly care for specific plants. Once the project began the owner was no longer involved. In fact, I never saw him again. In addition to his landscaping services I had him give me a bid for painting my new fence and yard fence. The painting itself was very nicely done however, the worker(s) were careless and left several oil based paint spots damaging 15-20 of my brand new pavers. When I addressed this with The Owner he replied via email his worker(s) told him they didn’t do it. I provided pictures of the pavers as proof to substantiate my claim. The Owner had his lead come by our home to fix a sprinkler head that was covered during sod repair and to remove these stains. When I reached out to The Owner again he solely relied upon his lead who promptly told him the oil based paint stains were removed. The stains still remain, I’ve contacted my pavers company who clearly stated “oil based paint cannot be removed!” It became blatantly obvious the owner was siding with employee. In fact, The Owner not once has stepped foot on my property since he took the bid. He never came to oversee the project and all contact with him has been via email or text. Lastly, we were in agreement to plant a new tree. As of this review, I have never heard back and there was never any follow up as to when this would be done. I really had high hopes In the beginning and I am very disappointed in The Owner’s project management. He appears to be knowledgeable but my recommendation is that he needs to manage his team, stay closer to the project and make an attempt to do a final walk through. Lastly his hourly bill rate was inconsistent vs. negotiated. Hourly rate doubled for final day of painting which I regretfully paid."

"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!"

"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."

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