"Bruce did a good job of keeping us informed when what would be done on our deck. Everything went so quick once we decided to go with them. The deck looks like new again."

"Our deck was in really bad shape and needed to be replaced. Select Craftsmanship was both professional and prompt. Sobi had great attention to detail and kept us informed every step of the way. He even checked in with our neighbors when he started building the shared fences, which they really appreciated. Our new deck is gorgeous, functional, and safe. We look forward to enjoying it this summer!"

"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."

"Jordan and his team do great work.  I had to be persistent in getting his estimate as I think he was really busy.  He also doesn't do a written estimate like the other two Angie's List recommended companies.   However, he stuck to his verbal/handshake pricing regardless of whatever problems he may have encountered.  We had some communication problems when we had to be out-of-town on a weekend in which his team was on-site working.  Because our property is on a hill, I had wanted the fencing tiered so that the redwood horizontal fencing would be level with the patio.  When we arrived home on Monday, we found that he hadn't done that on the critical rear portion of the fence.  When I said that we didn't like the downward slant of the fence, he agreed to redo it.  This added an extra day to the job - but he wanted to make sure we were happy with how the fence looked.   When he and his team completed the deck, I asked about putting a wood lattice around the bottom of the deck to keep animals out.  He said he would take care of it.  When I mentioned that the last step down on the deck was twice the length of the previous 3 steps, he came back and added another step to match the other three.   We had previously hired someone to do a deck and fence design, so we had some original drawings that we were able to show him.  This helped immensely.   If you're doing anything complicated, be sure to have your ideas well-thought out so you can be certain of getting what you need.   I would hire Jordan and his crew again.  His pricing was quite a bit less than the other two Angie's List Fencing companies for the exact same project and he takes pride in his work.   "

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