conservatory glazing repair testimonial

I contacted John Duffy of JD Glazing about my conservatory.  It was leaking badly and there seemed to be no way of tracing the leak.  John quickly identified the source of the leak, which at first seemed quite serious and costly to have put right.  But – in n time, John came up with an innovative solution and hey presto!  No more leaks.  I cannot praise John highly enough for his know-how, diligence, courtesy and cost-effective solution.  Thank you John!

nuala faulder double glazing repairs testimonial

I recently used JD Glazing to fit double glazed windows & French doors in my new home, from the very start of the process John made the whole things so easy, advising me on the best product for my home & the best value for money, I found JD Glazing’s prices to be very competitive. On the day of the installation they were so clean & tidy, the workmanship is outstanding & the finishing off was of the highest quality. I would highly recommend this company.
