Building a deck in Castle Rock

Even with Castle Rock's shorter warm season, a well-built deck makes the most of the outdoor months. Cold winters and freeze-thaw cycles mean footings set below the frost line and a stiffer frame — part of why deck costs here run a little above the national average. This area sees frequent severe weather, so impact-resistant materials and wind-rated fasteners and connectors are worth specifying. With local home values up about 40% over the past five years, an outdoor living space is a common, well-returning upgrade.
