"Excellent. My deck looks brand new. I did not think the deck would come out looking like I just had it installed. I am very happy with the results. Rich gave me a fair price and got the job done in a timely fashion. Thanks Rich. I will surely call on you in the future."

"Barb and her team were very helpful, professional and efficient. They cleaned the roof, porch, the deck and stonework around the house. The result was excellent, - we had moss growing all over the place and after the team did the cleaning the roof and all other surfaces look as good as new! Barb also gave us a lot of good advice on the proper care for the roof, porch, deck and everything else to keep the moisture, bacteria and moss away. I wholeheartedly recommend Barb and her team!"

"Went very well. They came on the day they scheduled. They protected the work area and prevented dust from getting throughout the basement and rest of the house. Cleaned up after themselves and even cleaned up stuff that wasn't theirs to clean. Left the space in better condition then when they arrived. Would definitely hire them again."

"They were prompt and efficient. Offered us the additional service of gutter polishing once they were here. It was not a hard sell approach, but they gave a demo of the difference it made and that was enough to convince us. Made the job look even more professional."

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