A range hood is only as good as the duct behind it. Here we run rigid duct from a gas range hood to a proper exterior termination, sealing the joints so grease-laden air actually leaves the house instead of leaking into the wall cavity. Done right, it vents quietly, pulls smoke and steam out of the kitchen, and lasts for years.
Rigid duct, sealed joints
We use smooth rigid duct instead of flex because grease and moisture cling to corrugated walls and the airflow loss is real. Every joint gets mechanically fastened and sealed, so the hood moves its rated air and nothing condenses inside the wall or attic.
Why venting outside is not optional
A gas range puts combustion byproducts, steam and aerosolized grease into the kitchen. Recirculating filters do not remove moisture or carbon monoxide. A ducted hood that terminates outdoors protects indoor air quality and keeps grease film off the cabinets.
Signs your existing hood vent needs work
Steam that lingers, a hood that roars but barely pulls a paper towel, grease streaks at the cabinet seams, or a flapper you never hear open are all signs the duct is undersized, leaking or blocked. We diagnose the run, not just the fan.
