    Excellent company to deal with

    We have used Double Glazing Doctor a few times now when glass units have misted. Mark is quick to show up quote then carry out the work. Would not hesitate to recommend him.

    Kitchen door

    Mark arrived on time , got started straight away. Removed the old wooden kitchen door very quickly. Mark was very tidy and cleaned up as he went along. He fitted the new double glazed door, which looks amazing. Very pleased with his work and his cost..
