Glazing Masters was able to visit and provide a quote for our patio doors a few days after initial call. there quote was very reasonable and there were able to confirm delivery of the new sealed units, would be within a couple of weeks, compared to other companies in the area advertising 6 – 8 weeks delivery. The new sealed units were duly installed and they look great. Glazing Masters team were personable and friendly. Would recommend Glazing Masters to anyone.
