JMG Steel - San Bernardino's Trusted Residential Fencing

Fence expansion damage is typically caused by temperature swings and moisture changes. In San Bernardino’s hot, dry summers, wooden fence boards expand and contract repeatedly, leading to warping, cracking, and loosening of fasteners. This is worsened by direct sun exposure on south- and west-facing fences.

Signs of heat warping include visible bending or bowing of boards, gaps between pickets, nails or screws popping out, and difficulty opening or closing gates. If your fence looks wavy or has sections that no longer align, it’s likely affected. Left unchecked, warping can compromise structural integrity.

JMG Steel recommends switching to metal fencing or reinforcing existing wood fences with metal components. They fabricate custom steel and aluminum fences, gates, and railings that resist heat expansion. For existing wood fences, they offer repair services like replacing warped boards and adding steel posts for stability. Their metal fabrication services also create decorative and secure options that last longer than traditional wood.
