"My only complaint is that as they cleaned the outside of the windows, they did not use a towel at the bottom to catch drips from the squeegee on the bottom ledge of the black-framed windows which left watermarks and drips below the window on the white siding. The owner is very friendly and the couple who cleaned was nice but not thorough enough for the price I paid."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"As always with any project I am having done around the house I got three estimates. All three people who showed up were very nice and knowledgeable about Trex and Timber Tech products. But only one picked up on the fact that the roof was shifting downwards on my front porch and that the columns that were supporting the roof were NOT under any deck support or concrete footings. John told us what was needed to be done to correct the problem and was still priced closely to the other two estimates with the work of jacking up the roof and resetting it being included. John and his guys were professional, polite, always on time and a pleasure to deal with, so much so that I hired him again later this year to do our back deck which was over 60 feet long, had two levels, a hot tub inserted in it, railings, bench, in the deck lighting and multiple styles of steps. All were done to perfection. I hired him for his honesty and keen eye on picking up on the sloping roof but ended up getting so much more. Not only did he fix the roof and redo the front porch to perfection, he transformed our back yard far beyond our expectations. He gave us great ideas on how to do the back deck and thankfully convinced us to amend our plans and we are so so grateful we listened to him. Honesty, reliability, master planner and consultant, professional, pleasure to deal with and reasonable priced, what more can you ask from someone and their company. FYI: This is my first company review I have EVER done; John was just that good."

FAQs for deck, fence, patio or porch clean and seal projects in Cold Spring Harbor, NY

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.
