Call this company first
Great company - clear communication from the moment I called to the job being completed. They resolved an issue with my double glazed door that I didn't think was fixable. They also worked quickly despite it being a difficult and challenging job, and cleaned up neatly afterwards. I would definitely give them a call first for any double glazing issues.Verified reviewerJob location: RM20
