How to Choose the Right Glazier for You

In many cases, large pieces of glass for windows or gates are precut and arrive ready for installation. Even then, it takes precision and strength to slide the glass in place. In the case where you might have a unique job that requires the glazier to manually cut the glass themselves, be sure to ask if they’ve done similar jobs in the past. You should also ask to see pictures of those jobs, to compare the level of difficulty or styles to your own projects.

It’s also helpful to know whether the glazier has experience working with the kind of glass you plan on installing, be it tempered, acrylic, aluminum framed, or vinyl. They may have four years of experience, but have never done a glass balcony enclosure before. You can start by reading reviews left by previous employers or homeowners. In the end, make sure your glazier can picture and execute your project with know-how from prep to finish.
