Glass door window repair is often offered by large home improvement stores such as Lowes or Home Depot. A quick search for local glass shops should yield at least several results. A local hardware store may be able to recommend a repair service.
Always make sure a glass repair or replacement shop is licensed and insured before hiring. For larger projects it may be worthwhile to get quotes from several different services in order to get the best deal.
If auto glass is required, contacting your vehicle insurance agent will allow them to recommend a reputable glass repair shop in the area.
