"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."

"Moises and his crew repaired water rotted wood in difficult locations and completely finished the garage to every detail from insulation to molding, as shown in pictures here. They thought of every detail that shows their pride over their work. Not only is their work top notch, but they are also easy to work with and very communicative through the whole process. I have already hired them for a second job."

"Jay and the entire crew from Long Island Decking were amazing. Not only was the quality of work outstanding but the entire team was such a pleasure to deal with. Jay was extremely professional and helped guide us through the entire selection process without ever feeling like were were pressured to go with one choice or another. Once things got started, they demolished our old deck, put up the new one, and cleaned up everything in just a few days. Beyond expectations! Everything looks fantastic and we are looking forward to enjoying our new deck for many years to come."

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