"Good value and good communication. Marco was able to start our re-decking project early due to weather conditions. He was very flexible with respect to keeping costs low, but refused to sacrifice quality. Late on a Friday he ran out of full length boards, and even though Iâ d approved allowing him to piece boards together, he decided to go back and get more wood since he didnâ t think weâ d be satisfied with the end result. He did this even though he knew it would delay the start of his weekend. Weâ re very pleased with the end result! Weâ ve recommended him to a number of people in the homeowners association."

"I found them to be extremely professional! They did amazing work and fit right in with my budget! They kept me in the loop prior to any change or additional recommendationsb I had to be at work while they completed my deck! They emailed me when they were done and they waited until my son took a picture so I could approve the project! I would definitely use them again !"

"Haven Landscape did a great job. After they completed the project you would have never known that a trench and drains were installed in the yard. Everything was restored perfectly. They identified the problem and resolved the issue."

Deck Maintenance questions, answered by experts

To flatten a cupped deck board, start by ensuring it’s dry. Then, try flipping the board over so the cupped side faces down and reattach it. If that’s not possible, you can use screws to pull it tighter to the joists or plane the edges slightly to reduce the cup. It’s best to replace severely cupped boards.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

Although composite decking is extremely durable, it’s also susceptible to extreme heat. Prolonged exposure to sunlight can cause fading, warping, and cracking. Composite also retains heat more than wood, which makes it dangerous to walk on in the summer. You can help prevent heat damage by only building with composite in shaded areas or using rugs to cover the hottest spots.

It is possible to build your own deck, but it’s typically better to leave the work to a decking professional. Decks can be exceptionally complicated, especially if you want a wrap-around or second-story deck, and you don’t want to risk making an expensive or dangerous mistake. It’s usually better to hire a decking pro who can pull permits and build a structurally sound deck that will last for decades and provide the maximum return on investment.
