"lou was on time, neat, did a fine job power washing, sanding and staining our old deck. He replaced a rotted potion of decking at no extra cost as well as other extras at no cost or minimum and extremely fair prices. I highly recommend LB Maintenance."

"Mario power washed, sanded and re-stained our back deck, pool deck and front porch. He’s very friendly, knowledgeable and met all expectations - and then some. All the furniture needed to be taken off the deck including a heavy grill and Mario not only helped to remove it, but came back a few days later (in between two of his other jobs) to help put it back - above and beyond! I would absolutely recommend him. "

"This was the first time we had our deck power washed and stained by Rob. It hasn't looked this good since it was built. He also replaced some broken lattice work and everything he did was in a very skillful manner. We've already asked Rob to do other jobs for us around the house. We highly recommend him."

"The front of my house was a green mess, Keith and Mary made my ten yr old gray siding & roof looked new. Made my 40 yr old garage roof look like a roof again. Very hard working and courteous on an extremely hot & humid day. Also cleaned my "green" fence back to white w/o me asking. Highly recommend & will use them again. Thanks for a hassle free job!"

"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."

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