"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."

"The crew was friendly and professional and washed the house, fence, two sheds, deck and walkways, and brightened up the entire property. They did a superbly thorough job on both smooth surfaces like white vinyl siding and rough surfaces like decks and roofs. Although the other quote I received was materially less, I was impressed that the Gulf2Bay owner visited the property beforehand and explained everything that would be done and also explained the superiority of the "softwash" method in terms of protecting surfaces and longevity of results. The crew cleaned up beautifully and everywhere they worked looks like new."

"Awesome team of workers. Jimmy came out to assess and price, and Chet helped us prioritize and find ways to meet our highest priorities. After 2-3 weeks of heavy rain, 4 roofers showed up to repair/replace broken slate tiles, seal valleys, and clean gutters. It was amazing to watch them work. Each roofer was down to earth, kind, and focused on the job at hand. Thank you!"

"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."

"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."

"Erik did an awesome job on my chain link fence. He was transparent with pricing from the beginning, explained everything clearly, and there were no surprises or hidden costs. The work was completed on time, the fence looks great, and you can tell he takes pride in what he does. It?s not always easy to find someone who is both skilled and fair. If you?re looking for quality work, fair pricing, and someone you can trust to do what they say they?re going to do, I?d highly recommend Top Tier Fencing."

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