Family-owned designers, builders, and refrigeration specialists — practicing a single discipline in Southern California for over twenty years.
M&M Cellar Systems was founded on a conviction that a wine cellar is not two projects handed between two trades — it is one discipline. The room and its climate are designed together, built together, and cared for by the same hands for the life of the collection.
Over two decades, that focus has made us the quiet specialists behind some of the finest private cellars in Los Angeles and Orange County — from waterfall glass rooms in Bel Air to hillside refrigeration in Calabasas.
We remain deliberately small, deliberately family-run, and deliberately obsessed with the details most people never see: the vapor barrier, the condensate line, the two-degree swing at 3 a.m. in August.
A handful of principles we don't compromise on — on every room, at every price.
Design, construction, and refrigeration under one roof. One phone number, one standard, no finger-pointing between trades.
Vapor sealing, correct load calculations, and commissioned systems — the invisible work that keeps a cellar stable for decades, not seasons.
We're authorized for every major manufacturer and specify the system the room needs — never the one we're trying to move.
A cellar should be felt, not heard. We engineer for silence in the living spaces that surround it.
Our reputation is built on service calls, not upsells. We fix what needs fixing and leave the rest alone.
We work in private homes for private clients. Care, cleanliness, and confidentiality are non-negotiable.
Out of all our providers, Mario and M&M Cellars are number one.
