Wood Decking

Wood is still the homeowners choice for building a deck, it’s naturally strong and easy to use with common woodworking tools. Plus wood weathers naturally, requires minimal maintenance and is a sustainable product throughout its life cycle. We carry Redwood and Ipe decking.

Redwood Decking

Redwood has long been a good choice for building a deck where durability, dimensional stability and resistance to insects and decay cannot be compromised. Our Redwood is harvested from sustainably-managed forestland along Northern California’s coast. Fine-milled close to the source, this Redwood tends to be a better grade than what’s available at any home improvement center. Redwood is fire-resistant and there is no other decking material that comes close to the rich, authentic beauty found in Redwood.

Ipe Hardwood Decking

Ipe (pronounced E-pay) is a sustainable tropical wood harvested from one of the tallest trees in the Amazon Region. Ipe is a very dense wood that is resistant to fungal decay and termites. The tight grain can be wavy or straight and Ipe’s rich brown color contains red and amber hues. This is a low-maintenance hardwood decking material that because of its density, holds up very well under traffic and heavy use. Ipe hardwood decking has a Class A fire-rating, making it a good choice for use in high-fire areas or building in Wildland-Urban Interface (WUI) zones.

Choosing the right decking material

Deck styles and sizes are as varied as the homes they are attached to, and choosing the right decking material is really a matter of personal choice. However it is important to keep in mind your usage, the deck location and the type of weather your deck will be exposed to, as well as the overall design and aesthetic look you are trying to achieve. Will your deck be in the sun or shade, as wood tends to be cooler under bare feet. Will your deck be exposed to lots of rain or snow, as there are many products that provide added protection from the weather. Whatever you choose, let us help you to create a beautiful and durable outdoor space you’ll enjoy for years to come.

Composite Decking

Traditionally decks have been made of Redwood, but with the advent of green building came the manufacture of composite decking materials. These low-maintenance alternatives to wood come in a wide range of colors, textures and grain patterns that require no painting or staining. All have matching components available, like railing and lighting systems to complete and enhance your outdoor living space.
