“Great Harwood windows have been very professional and patient with us when you could have taken a different approach.


I will recommend your company and team and as and when we require more windows I will be in contact directly not thru a 3 rd party as we have other products from you that have been perfect. “

“I just wanted to feedback from today’s installation. From start to finish, we only have compliments. Every contact has been profressional and straight forward, all company employees I’ve met when they measured up, and when installed, have all been an asset to your company. The standard of the fitting of the windows is perfect, and the courtesy of each person has been exemplary. I don’t usually send reviews or emails like this, but I feel that I should on this occasion due to such an amazing positive experience. I’d highly recommend your company to others. Thank you very much.”
