Customers say: Quality work

"We initially hired Polanco Brothers to repave a large driveway. They did such a good job on the asphalt replacement we asked them to install a new bluestone/brick front walk and side patio and make repairs to the front steps. The quality of all their work is excellent. The driveway looks better than new, and the walkway looks as though it has always been there. They went out of their way to match materials. Their prices were fair. The workers are polite, courteous and professional. They took great pride in their work, and truly cared about providing a quality result. We are completely satisfied with their work, will certainly use them for other projects in the future and would highly recommend you consult with them on similar work."

"Gulf2Bay did an excellent job. Our roof was covered in moss & mold. After G2B completed their work, my roof looked new again. They did an excellent job power washing & cleaning our vinyl siding. They also cleaned our paver patio and composite wood deck. Both looked great. Several neighbors commented how great our house looked after G2B completed their work. It should be noted that they showed up promptly on the date scheduled and abided by the COVID recommendations."

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