MillCon Trim Inc. is a finish carpentry contractor based in Idaho Falls, specializing in doors, windows, and trim for both high-volume production builds and high-end custom homes. We supply and install every project ourselves, giving builders and homeowners a single point of accountability from material to finished product.
In just 3 years, we've completed over 107 projects and built lasting partnerships with builders across the region — including Hamlet Homes, RPI, Gate City Builders, Summit Building Group, and Kartchner Homes — by showing up on schedule and delivering work that holds up to inspection every time.
Licensed (RCE-68767) and built to scale, MillCon Trim is equipped to handle everything from a single custom home to a full subdivision.
Every cut and install held to the same standard, whether it's unit one or unit forty.
Builders count on us to show up on schedule and keep their timelines moving.
Long-term relationships with builders, not one-off jobs.
