Deck Repair questions, answered by experts

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. 

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.

Yes, it’s definitely possible to build a pergola on an existing deck. All you need to do is attach the pergola support beams to the deck’s joists and build up from there. Beware that mistakes can damage your deck, so if you’re at all unsure of the process, play it safe and hire a pro for your custom build.

Before installing a deck, you must build a base for the deck to rest upon, often made of compacted soil or gravel. While gravel is an optional material, it helps with drainage. Some contractors also recommend installing a weed control membrane, which helps provide a solid foundation for the frame. In the case of an elevated deck, a pro will often lay down a concrete slab as a foundation. 

Yes. Composite decking is resistant to moisture and freezing temperatures, so it’s an ideal material to use in particularly cold or damp seasons. You can install this type of decking throughout the year since it does not warp or split in the cold.
