What Our Customers Say

"Great Communication"

"Used Treforest Glass for a large order of glass units in many different sizes. No issues at all with communication and the order was spot on with free delivery. Have used them again since and would recommend to anyone."

John Bennett
"Brilliant Staff"

"I work for a company that had placed the order. The lady on reception is the reason for the review, she knew exactly where my pane was and even advised me how best to store it in the van. Pane was exact size with no visible defects."

Christian Lang
"Excellent Value"

"Excellent value for money. Fitted two large patio windows. The order was almost £300 cheaper than a quote from a well known UK wide replacement glass company. Will definitely use Treforest Glass again in the future."
