Dartmouth Building Supply Real Cedar Wood

With its charming, rustic look and natural resistance to insects and decay, cedar siding is an attractive and practical option for your home’s exterior. Both red and white cedar are used for siding materials, but there are differences between the two species. Red cedar siding is usually more durable and comes in a variety of styles, so you have more design options for your home’s exterior. White cedar siding only comes in one style, so its design possibilities are limited. However, when you want a light look for your home’s exterior, white cedar weathers to an attractive silver-gray shade. When you prefer saturated colors, both red and white cedar siding can be stained in a variety of shades. You can even have new white cedar siding bleached so it is immediately the silvery color that usually develops over years of weathering in the sun.
