GarageCo (Gridiron Capital)
The Firm
GarageCo Holdings was formed in March 2024 by Gridiron Capital as a platform company of its Fund V, to build a national residential and commercial garage door services business out of established regional dealers. It launched with three at once: P.D.Q. Door Company in Maine, Apple Door Systems in Virginia, and Cunningham Door & Window in Kentucky.
It has kept buying since, and the sponsor announces each one: Cedar Park Overhead Doors in May 2024, Quality Overhead Door in July 2024, Dan's Overhead Doors in August 2025. The companies keep their own names, which the platform calls a family of family brands, so a market can be consolidated without looking it.
That last point is the one a searcher should take away. The trade reads as fragmented and local from a listing site while a funded buyer is working it steadily, and the brand a seller keeps is part of what is being sold. A first-time buyer bidding here is bidding against someone who has done this repeatedly and does not need the seller to leave.
Read again in September 2026: one more since Dan's, an Omaha company in November 2025, announced on the platform's own site and not the sponsor's, which posted the first ten and has posted nothing about it since. The platform's own count of ten runs through four partnerships the row lacked, and the founding release prints March 6, 2024, the day the row carries now.
What It Buys
New Canaan, Connecticut. Founder-run garage door dealers bought into a national platform assembled from scratch since 2024, each one keeping its own name, which is why the trade looks less consolidated than it is.
