Pro-Line Window Co have just completed an exceptional installation of replacement windows, doors and porch to our cottage. From the initial concept and quote by John, the detailed measure by John and Matt and the precision installation by the team ( Matt, Paul and Chris) Pro-Line make the process very simple. The product supplied is of the highest quality and look amazing. The team did a great job of installing the product especially during Storm Berra and leave no mess behind. I could not recommend this company enough and if you are in search of replacement windows then this is the company to

John and his team kept us informed about our order for replacement doors due to delays beyond their control, soon as they arrived they arranged to fit them two days later. The two man team did a fantastic job and left no mess behind. We are thrilled with the new doors and wish we had replaced them earlier, we would highly recommend.

Really delighted with new sash windows, transformed cottage from a semi-derelict to period, which is what it always was. Paul did a fantastic job in fitting them leaving no mess afterwards. And they were fitted just before the heatwave hit, meaning I could breathe easy even in the baking temperatures.
