Air sealing at an attached garage is intended to reduce uncontrolled movement between the garage and occupied space. It is a building-science intervention, not a substitute for every fire, combustion, or code requirement.
Ventilating an attached garage can affect pollutant movement, pressure, noise, moisture, and the house's air-control strategy. An exhaust fan is not a universal fix and should be designed around the actual garage and adjoining spaces.
Garage insulation cost depends on which surfaces and assemblies are being changed. Walls, ceilings, doors, air sealing, moisture, adjoining rooms, and finish work make different projects.
