Fiberglass Front Doors

Knockety fiberglass front doors look like real wood: a wood-grain texture with stained-wood finishes, built to order in Houston, Texas, and shipped free anywhere in the continental U.S. Most fiberglass models are impact rated; a design rep will confirm yours.

Fiberglass doors that look like wood

Our fiberglass doors come in two tiers, FiberCraft Premium and FiberCraft Pro. Both have a wood-grain texture with stained-wood finishes, multi-layered cores built to resist warping, swelling and rot, and double-pane glass on glass doors. To compare the grain and color with real wood, order a fiberglass finish sample.

Built to order in Houston

Custom fiberglass doors are built to order by our team in Houston: trimmed and machined on a CNC, where the fiberglass skins are applied, then finished, glazed and, if you choose, prehung in its frame. Custom-built doors take about 5 weeks: 4 weeks to build in Houston, then about 1 week in delivery. Quick Ship doors, hardware and samples arrive in about 1 week.

Fiberglass or wood?

Choose fiberglass for the wood look at a lower starting price and the longer Premium warranty. Most fiberglass models are impact rated; a design rep will confirm yours. Choose solid wood front doors for real mahogany or knotty alder.
