Hot, fast, logged.
The hood gets clean, the
permit holds, the air
balances.

If your kitchen runs more than thirty hours a week with grease-laden vapor, the hood is a piece of fire-rated equipment under the same legal regime as your suppression nozzles, and the city of Houston wants the trap pumped quarterly whether you have a busy night or a quiet one. We treat both like the regulated assets they are.

Updraft Mechanical Co. opened on Navigation Boulevard in 2021. We service forty-six restaurants, two food halls, and a cluster of ghost-kitchen tenants between Spring Branch and the East End on a quarterly route. We are not a sales floor. We are a small crew — three certified hood-cleaning technicians, one TDLR-licensed mechanical contractor, and a dispatcher — who would rather walk a hood than write a brochure.

Every contract is per-hood, per-quarter. Every visit produces a record: the hood plenum is photographed before and after, plenum and duct grease accumulation is measured against NFPA 96 §11.4, and a UL-300 nozzle map is checked. Records live in your operator portal and roll up to the season card you can show an inspector at the back door.

What we ask in return: a key to the kitchen, an honest answer about whether the wok station saw a fryer fire last quarter, and forty-five minutes when you can run cold-side prep without the line on. The work is paced to the kitchen, not to the route.

What we have been writing about

A field shop's notebook on Houston commercial kitchen ventilation — code changes, mistakes that cost an operator a permit, and the long argument with belt-driven exhaust fans.

Walk your kitchen with us before you sign anything.

A walkthrough is forty-five minutes, no obligation. We start at the rooftop fan, move down the duct, and finish at the hood plane with a smoke pencil. You leave with a written grease-load reading on every hood, a flag list, and a written quote you can hand to your accountant.

Loaded for a Tuesday night route. Magnolia Park, then Heights.
