Auto glass, residential, and commercial are three distinct businesses
Identify which sub-category the business actually operates. Auto glass replacement is largely insurance-driven, high-volume, low-margin, and dominated by national chains (Safelite owns much of the market). Residential window and door service is consumer-direct, project-based, seasonal, and higher-margin. Commercial storefront installation is contractor-relationship-driven with larger project size and longer sales cycles. A glass business operating in all three is really three businesses with different operating profiles.
