"Very professional and polite turning my cracked up patio into a beautiful space that makes me want to go outside again. They took me thru process step by step, showing me progress as they finished each steps. Answered questions and or concerns as we progressed. The crew were delightful to work with. Now if I could just get my HOA to approve a glass topper on my wall my patio would be near perfect LOL. SERIOUSLY, great job!"

"Couldn't have gone better. I was under a time crunch because my tenant moved out and I didn't want to let the house sit a whole month without income. I urgently read AL reviews and called 5 companies.
Don, the owner I think, of Foothill came out himself at a time that worked for me. He immediately impressed me with his insight, friendliness and his suggestions of how to keep costs low while not skimping on quality. He worked with me on price and I gladly gave him the job. Couldn't be happier, I was on the road for work when the work got done and thankfully it went off without a hitch; no calls, no extra charges, no delays. The place was sparkling and beautiful for our new tenants upon move-in.
Foothill has a customer for life.

"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!"

"Overall the job took the better part of a week and from our perspective was a success.  Ryan worked with us in selecting
the right color for the stain.  He carefully removed and replaced the numerous potted plants we had on the deck and left
the work area in a clean condition.  The patio and balcony look great and our only regret is that we didn't do it earlier."

"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.

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."

"Excellent! The team was very well organized and did a great job with the painting! We asked for a couple additional beams to be painted and they were great about taking care of that. They cleaned up everything when they were done and the price was very reasonable."

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