Bespoke French Cookers
La Cornue Service for the Heirloom at the Heart of Your Kitchen
A La Cornue is not really an appliance in the ordinary sense. It is a commissioned piece, hand-assembled in France, chosen in a specific color with a specific trim to anchor one particular room, and built with the plain expectation that it will outlast the kitchen around it.
We are an independent shop serving Highlands Ranch and the wider Douglas and Arapahoe County area, and we treat these cookers accordingly: a flat $89 diagnostic, a repair figure quoted only after we have the range open in front of us, and parts matched to your exact build.
A Cooker Built to Be Kept, Not Swapped Out
La Cornue was founded in 1908 by Albert Dupuy in the outskirts of Paris, and the invention that made the name was the vaulted oven, a domed cavity that circulates heat in a gentle vortex instead of blasting it from one direction. More than a century later the company still builds each cooker by hand, to order, in France. A La Cornue is a commission: you choose the color, the brass or nickel trim, and the burner layout, and what arrives is closer to furniture than to a boxed-up range from a warehouse.
That craftsmanship is exactly why these cookers reward repair. The Flammes de France burners are heavy, rebuildable brass rather than stamped consumer parts; the oven relies on straightforward elements and sensors; the trims and knobs are made to be refinished or replaced rather than thrown away. A well-kept La Cornue routinely passes from one generation of a household to the next, and the components that wear are precisely the ones a skilled technician can renew.
It is also, undeniably, a generous source of heat in the middle of a room, which matters in a Colorado home. In a warm month, all that radiant warmth adds to what your refrigeration is quietly working against, so we think about the kitchen as one system. When we come out for the cooker, we are happy to glance at the appliances that carry the summer load with it.
What We Look After on a La Cornue
A cooker made of real, rebuildable hardware gives you decades of service, and every one of its strengths has a corresponding part we know how to renew.
The Vaulted Oven
We service the elements, sensor and controls behind the signature domed cavity so it holds temperature and browns evenly, without ever disturbing the vault that defines it.
Flammes de France Burners
Heavy brass burners are made to be cleaned and rebuilt. We clear ports, reseat caps and restore a tight blue flame that recovers heat the instant a cold pan lands.
Ignition and Gas Valves
Spark modules and valves take the most cycles on any range. We trace no-light and endless-clicking faults and renew the ignition or valve rather than guessing.
Dual-Fuel Electric Ovens
On dual-fuel cookers we handle the bake and broil elements, the temperature sensor and the control board that give these ovens their steady, even heat.
Brass, Nickel and Enamel
The finishes are part of what you paid for. When a knob, bezel or handle fails, we source the matching trim so a repair never announces itself on the front of the range.
The Kitchen Around It
A cooker this warm shares its room with refrigeration and outdoor appliances that work hardest in summer, and we are glad to look at those on the same visit.

Frequently Asked Questions
It is peak summer and my kitchen already runs warm. Does a cooker this size make it worse, and can you help with the refrigeration too?
A range with this much cast mass genuinely holds and radiates heat, so during a hot Highlands Ranch July it adds to the load your cooling equipment is already carrying. That is one reason we look at the whole kitchen rather than a single unit: if your built-in refrigerator, wine storage, garage freezer or an outdoor beverage center is straining against the summer heat, we can check those on the same trip. Tell us everything that is acting up when you call (303) 729-0972.
How does the vaulted oven work, and can it actually be repaired?
The vaulted oven is La Cornue's signature: the ceiling of the cavity is domed rather than flat, which sets the hot air moving in a slow, rolling circulation that browns evenly and keeps roasts from drying out. It is an elegant piece of design, but underneath it still relies on ordinary serviceable parts, including heating elements, a temperature sensor and a control board. When one of those drifts or fails, we repair it without disturbing the vault itself.
Are parts still available for an older La Cornue?
Usually, yes. Because each cooker is hand-built to a durable standard and the core architecture has changed slowly over the years, ignition parts, valves and elements tend to stay obtainable long after a mass-market range would be orphaned. We confirm availability for your exact model once it has been diagnosed, and we tell you honestly if a part has become hard to source.
Which La Cornue models do you work on?
We handle the residential range lineup we encounter locally, from the fully bespoke Chateau and Grand Palais cookers to the more compact CornuFe series, in gas, dual-fuel and electric configurations. If you are unsure which line you own, the plate behind the door or a photo of the range is usually enough for us to identify it.
What does it cost to have a La Cornue looked at?
Every visit starts with the flat $89 diagnostic. Common repairs begin around $139 and climb depending on the part and the labor involved, but we never name a final figure sight unseen. You receive an exact price after the technician has inspected the cooker, and only then do you decide how to proceed.

What Highlands Ranch neighbors say
Called just before six in the morning fully expecting to leave a voicemail, and a real person picked up. Our garage freezer had quit overnight in the June heat with half a side of beef sitting in it — the condenser fan had seized solid, and he already had the replacement with him, so it was done in one visit. Not a thing thawed, and he was decent enough not to comment on the state of the garage.
I had already started pricing new dishwashers. Every glass was coming out of the Miele with a chalky grey film on it and nothing I ran through the machine made any difference. The real culprit was our hard Douglas County water: scale baked hard onto the heating element, and a spray-arm bearing worn enough to wobble. He descaled it, fitted the new bearing, and corrected a water softener setting that had apparently been wrong since the house was built — clear glassware again, for a small fraction of a replacement.
Sixty-two degrees is not where you want a cabinet of reds sitting, and by then the display had gone dark as well. A power blip earlier that month had cooked the control board; he confirmed that on the first visit, got the correct board, and fitted it a couple of days later. What I appreciated more was that he then set a target temperature our basement can genuinely hold — at 6,200 feet it swings far more than people expect — rather than leaving it on a number that would have the compressor fighting all year.
The griddle on our Wolf had gone from useful to useless, scorching eggs on one pass and barely setting them on the next. He put a meter on it, found the griddle plate thermostat reading well outside its range, and swapped it. Then he checked the oven calibration while he was in there without my asking, which up here matters more than most people realise. The invoice matched the number he gave me before he started, to the dollar.
Every couple of weeks we were chipping a sheet of ice off the freezer floor and mopping up after it. The drain-line heater had failed, so defrost water was refreezing before it ever reached the drain — a genuine part went in and the ice has not come back once since. He also pulled the grille and showed me how much dust a Westridge summer packs into the condenser, which I now vacuum on a schedule.
The humidity control in our undercounter wine drawer stopped regulating and the corks were starting to dry out. I have to be honest about the scheduling: we were given an arrival window twice and both times they turned up well outside it without a phone call, so an afternoon went to waste. The technician himself was excellent — he explained what the humidity module actually does, fitted the replacement, and it has held steady ever since. Good work, but the dispatching needs tightening up.
