They are very professional, honest, timely, courteous, and meticulous in keeping the work area clean. They also pointed out and corrected a couple of other issues with our deck. We will surely contact them for our next construction project."

"I had an amazing experience working with Mike, the owner of this company—professional, skilled, and incredibly efficient. He installed a new kitchen faucet for me, and the job was done flawlessly. Not only was the installation clean and precise, but he also took the time to ensure everything was functioning perfectly before wrapping up. It’s rare to find someone who takes so much pride in their work, and his attention to detail truly showed. Even more impressive was the transformation he did in my bathroom. He converted my single-sink vanity into a beautiful double-sink setup, complete with a new mirror and lighting fixtures. The entire space looks like it came out of a design magazine! He handled everything—from plumbing to electrical—with confidence and care. If you’re looking for someone reliable, trustworthy, and extremely capable, this is the person to call. I can’t recommend him enough!"

"Jorge arrived early in the day, as promised, and got right to work on power washing my 2-story home in Woodbury NJ. By the time I got home from work my house was sparkling clean. The front of my vinyl sided house faces due North. As a result, the black mildew/moss staining was very pronounced there. Additionally, the white vinyl fence that hides my trash cans was covered with those little black mold spore dots that comes from wood mulch being placed nearby. Very difficult to remove. Jorge has that fence looking as white as the day it was manufactured! I don't know what time he finished at my house, but by the time I got home from work at 4PM, he was done, every piece of lawn furniture was back in place, the house was gleaming, and he was gone! If you want an "OKAY" job done at your home, hire that huge company with the big employee turnover rate. If you want results that have you declaring, "WOW!", Monarch Power Washing's Jorge is your guy. You won't be disappointed!"

"We recently hired Family Paint and Drywall to complete some painting and drywall work in our basement. Kevin, the owner, was easy to communicate with and provided pricing quickly after our first meeting. The crew was friendly, tidy and professional. They completed the job a day early and left our house as clean as they found it. We are so happy with the finished product and we will be using them again!"

"Many thanks to Pro Fence and Deck team for job well done. First off, it was great to get a response to my query so quickly at a very affordable price with an upfront timeframe. Serge explained exactly what he intended with the fencing project, particularly since there was a slight slope involved and if we were all in agreement. Even questioned size of our dog to make sure any avenues of escape were covered. They were very professional, courteous and extremely easy to deal with at all times. Again, a job well done, greatly appreciated and extremely happy with results. I absolutely recommend them and would not hesitate to use them again."

FAQs for deck, fence, patio or porch clean and seal projects in Williamstown, NJ

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.
