"I am very pleased with the workmanship and the service. Julio is very easy to get along with, very respectful. I fully trusted his judgement. I did not feel pressured to doing more than what was needed to clean and seal my redwood deck. He was very reasonable, worked hard and I love the results! The wood looks newer and is protected for the upcoming winter. I am very happy, and highly recommend them."

"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!"

"We were thrilled with the work Ramirez did on our backyard landscaping. The staff were professional, timely, and highly skilled. We especially loved the stamped concrete patio, the elegant paved border, and the lava rocks. They planted over 100 plants and expertly installed our irrigation system. Roberto and his team have been incredibly responsive, even handling additional small tasks like irrigation fixes. We highly recommend their services."

"They installed about 160 feet of redwood privacy fence with three gates and an additional gated enclosure for a heat pump. For the wood fence itself they did excellent work. Quality material and accommodated some unusual features which meant the entire job was done by one contractor. The owner suggested and installed special gate latches that allow entry with a code on a keypad, which actually got them the job. Their failing was the crew doing the work did not understand how that special gate latch worked, and how to construct a gate to properly use it. I am handy with tools so I was able to spend a day to modify and add to their work to make the latch work. Not everyone is in a position to do that. They over-promised in that crew doing the actual installation needed more guidance for a completely successful installation. So if you have a standard fence and gates with standard Home Depot style hardware, I would recommend them. But if you need something unusual they really are not able to handle it and you need to plan to get that skill set elsewhere."

"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!"

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