With over 20 years window experience he knows his transom from his mullion. After working together with Andrew for years, they decided to start Secondary Glazing NI and have never looked back!
Andrew is an intelligent, diligent and practical hands-on Armagh boy. On leaving school trained as a mechanic, and ran his own business for years. From there he worked in the window industry, where his practical personable manner and thorough knowledge set him apart from the rest. He is very detail driven, always looking for the best for his customers, in terms of the right product, best value and if it is the best practical option. In Secondary Glazing, he has a keen eye for detail, does not accept ‘nearly do’, and will ensure that the right product has been explained, ordered and fitted correctly. If you are looking for the right window, fitted right, then this is the man to speak to.
