Be sure to check the local building codes and regulations to determine what guidelines and restrictions you must follow. Consult a building professional if the area is to be extensive or the construction difficult. If you decide to do it yourself, you may want to divide a large deck project into small manageable projects, so your building experience, budget and outdoor living can grow each year with your deck. Redwood is a classic for decks because it is great looking, resists weathering and is easy to saw and use. The heartwood grades naturally resist insects and decay.
Redwood has no chemical additives and resists warping and splitting better than other woods.
The rugged, knot-textured garden grades, which are more economical than architectural grades, are ideal for outdoor structures. Choose an all-heartwood grade such as Construction Heart or Deck Heart for applications on or near the ground. When working with redwood, always use top quality, hot dipped galvanized, stainless steel or aluminum hardware. To avoid splitting, pre-drill holes for nails or screws at the ends of the decking boards. Redwood takes and holds finishes better than most other woods.
