Your deck may pop, and your neighbor’s deck may not for a number of reasons. Whether or not a deck pops will depend on how it was made, the conditions it’s exposed to, and the materials. Improper spacing is a common reason for increased pressure between deck boards. Moisture penetration is another.

You can nail or screw composite decking, but 3-inch decking screws are the better fastener choice. Unlike nails, decking screws won’t back out of the composite material over time. There’s also little danger of splitting composite material when driving screws, so you don’t need to pre-drill holes unless otherwise recommended by your decking manufacturer.

Yes, you can attach a deck to a mobile home, but it’s important that the work be done correctly to avoid the potential for major damage to your home. Many building codes require that any additions to mobile homes—including decks—be either freestanding or have their own support structures. Getting permits may require submitting the home's original floor plan, the proposed floor plan, framing details, and more. 

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.
