How to Hire a Glass & Glazing Contractor

Glass and glazing contractors specialize in custom glass work including storefront systems, shower enclosures, mirrors, glass railings, tabletops, and insulated glass unit (IGU) replacement. When a sealed double-pane window fogs between the panes, the IGU seal has failed and a glazier can replace just the glass unit without replacing the entire window frame. Commercial glaziers handle curtain wall systems, automatic doors, and specialty architectural glass. For residential work, a qualified glazier can custom-cut tempered glass for showers, replace broken panes, and install decorative glass features.

Typical cost

$150 – $800per unit

Single-pane replacement: $150–$400. IGU (foggy window) replacement: $250–$600. Frameless shower enclosure: $800–$2,500. Commercial storefront glass varies widely.

Hiring checklist

1Ask whether they supply the glass themselves or source from a local fabricator.
2Confirm tempered or safety glass is used where building code requires it (showers, doors, near stairs).
3Get a written estimate specifying glass type, thickness, and any coatings.
4Ask about lead time for custom-cut or specialty glass orders.
