What our customers say?

"KNM were recomended to us so I thought Id visit their office in Pyle to get a quote. I was shown around the factory which looked impressive and well organised - a good start. Their quote was competitive and I got a good feeling so we went with them. We werent dissapointed. Tony and John worked hard, were professional and cleaned up as they went along. We are very pleased with the windows, one of which is 4.9m in width. The windows are of a high quality, sturdy construction and we would definately recomend KNM, they ticked all the boxes for us."

"Exceptional customer service again today. Came out within hours of my call to fix front door lock and help me out of a really difficult situation. I really appreciate the professional attitude, and immediate response. The windows and doors you fitted several years ago still look stunning. Great company."
