"Dave was punctual and was very hardworking, making sure my new decking system was installed correctly. He took the time to install each layer of the decking system and made the finished surface graded so the water drained off perfectly. I would hire him again if I ever need to redo my deck."

"We hired Pennington Construction to remove our existing patio and install an Alumwood patio. The project went smooth, communication with Eric and Elissa was effortless. The crew was great, I will be using them for future projects as Eric is a general contractor and fumigation company."

"I had OC Decks repair my existing deck which had numerous structural and esthetic issues. They were so professional throughout the process. Even when change orders came up, they explained everything thoroughly and left decisions to me throughout the project. The workers were neat, timely, experts, and hardworking. I felt like they made safety a priority and they did not rush anything. I am pleased with the final product and I would hire them again in the future."

"It was done professional and their communication was very good, however, we chose not to go with them. I have no complaints, I just wasn't' happy with the price, which is not their fault."

"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!"

"While they were up there cleaning the gutters they told me about the deterioration of all the sealants on the air vents, the chimney and exhaust fans on the roof. They took pictures and showed me and I had them redo all the sealants. I have a feeling that that was a smart way for them to get some more work (most people aren't aware of the damage the Ca sun can do). It was the owner of the company and his son that did all the work and they were clean, pleasant and professional. When the 1st rains came after the work was done I suddenly remembered a small leak we had had in our bathroom and IT WAS NO LONGER THERE!! I was very happy with the work they did and would definitely recommend using them."

"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."

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