"Cal Preserving did a great job on our very difficult to install Ipe (Brazilian Walnut) deck. I would definitely use them again."

"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!!"

"Needed to get about 150 feet of railing prepped and painted, as well as 6 pieces of outdoor wicker furniture. Platinum Painting did a very good job and promptly arrived each morning first thing. Excellent clean up each day. Very satisfied."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly. <br /> <br /> I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"Fredrick was awesome! There was a ton of prep work needed for this job the walls needed to be hand scraped then primed and painted. He was quick and efficient, and the end product was beautiful. He also handed the rental of the lift which is something I was asked to from others, as someone in the middle of starting a business it was little details like this that were so very helpful. His pricing was fantastic, I got 3 other quotes and his was by far the most fair. We will definitely use him for future projects. Thanks Fredrick!! <br /> <br />"

"The power wash and clean-up were both very perfunctory. Many garden plants are speckled with paint. That said, the price was very reasonable and the house has been painted. Considering the hasty prep that was done, I only hope the paint job lasts a few years. <br />"

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