Founded in 1996, Mark Smith Glazing Ltd has built a strong reputation across Scotland for quality craftsmanship, transparent and competitive pricing, reliability, and a customer-focused approach.

Backed by a dedicated and highly experienced team of glaziers and joiners, we deliver professional glazing solutions for both domestic and commercial clients, handling everything from small same-day repairs to large-scale installations.

In 2006, the business expanded with the acquisition of J&B Windows, allowing us to broaden our product range and in-house manufacturing capabilities. Today, we supply and install uPVC, aluminium, and composite windows and doors, alongside specialist glazing products including roof lights, shop fronts, and bespoke glass solutions.

We cover all domestic and commercial glass and mirror work, including secondary glazing, shop fronts, integral blinds, energy-efficient windows, sash and case windows, patio doors, balustrades, balconies, and roof lanterns.

For dependable workmanship, expert advice, and high-quality glazing solutions, Mark Smith Glazing Ltd is the name you can trust.
