Glazing businesses supply, install and repair glass and glazed products for homes, commercial premises and other buildings. Work may include fitting replacement panes, repairing cracked or misted units, installing double- or triple-glazed windows, and replacing or adjusting window and door frames, hinges, locks and seals. Some firms also provide glazing for shopfronts, offices, conservatories and internal partitions. Products and services can include toughened or laminated safety glass, patterned and decorative glass, mirrors, splashbacks, shower screens, balustrades and glass doors. Customers may ask for glass to be measured and cut to size, or for advice on choosing a suitable type for its location and use. Services vary by business; some focus on domestic repairs, while others undertake larger commercial installations or offer emergency make-safe work, such as boarding openings after glass has broken.
