What People Say…

“I’m always so impressed with the service from the entire team at masterframe. Recently, I called the office while I was with a customer. I needed some information quickly, to help me to close an order. With an average window supplier I wouldn’t usually make this call, as typically I can wait hours or even days for the right information, but I knew masterframe would react straight away with the right information. In this instance carol and jane between them had an email over to me within minutes, and my customer was very happy. Top quality service from knowledgeable staff as always. Thank you!”
