we had our old deck replaced with a new bigger deck with stairs. The finished deck looked great, had approval from the building inspector and met our needs. It was a pleasure to work with them as they listened to what we wanted and provided the results. Highly recommend them

Deck Maintenance questions, answered by experts

How long it takes to install composite decking depends on the size of the decking material, the skills of the person installing the deck, the number of people helping, and how much prep work needs to be done before you can begin. Generally speaking, it takes anywhere from a few days to several weeks to build a composite deck.

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.

While eco-friendly decking, also called composite decking, is a win for the environment because it consists of recycled materials, it has trade-offs. These sustainable options often come with steeper price tags, lack natural wood's warm look, and can become uncomfortably hot under full sun. Some composite materials can also become slick when wet, posing a potential hazard.

Yes, you can draw your own deck plans in many cases. However, you must know your local building codes and be familiar with carpentry principles. Even then, it's always best to run your plans by a professional contractor with experience building decks, whether you choose to DIY some of the build or not.

No, termites do not eat Trex or any other composite decking brand. Termites eat cellulose, of which composite decking like Trex contains very little compared to natural wood. This feature can help justify the higher Trex decking costs if you live in an area with abundant termites.
