Shims & Blocking

Shims and blocking may never be seen, but they’re essential to the structure and success of every door, cabinet, and trim installation. Used to level, support, and distribute load, these hidden elements ensure everything stays aligned, plumb, and solid—day after day.

We supply a range of materials from traditional cedar shims to composite and plastic options for moisture-prone environments. Blocking materials can be pre-cut or job-site fabricated, and we often advise on layout to support hardware, anchoring points, or wall-mount accessories.

Clients lean on our expertise for best practices in placement and fastener selection, especially in pre-hung door installations and heavy hardware applications. It’s a quiet detail—but one that separates a clean, long-lasting result from a callback waiting to happen.
