Residential Services

CMJ treats every residential fence project individually and aims to meet the goals you have for your home. We are seasoned at navigating local safety regulations or codes, and gaining approval from your homeowner’s association (HOA). Whether you’re looking for privacy, marking property lines, or containing animals, we can guide you toward a fitting and attractive solution. We work with many materials such as wood, metal, or vinyl, and can build rolling, latched, or high-security gates.
