Trustindex verifies that the original source of the review is Google. A small job but huge professionalism! 2 of my double glazed windows needed replacing. I loved that Gabriela didn’t put me off as other companies had & was willing to help especially being local. Every aspect of the job has been professional and friendly .. I thought I’d have to repaint the wooden frame but not so .. the repair is like new and carefully and tidily carried out. I’m very pleased indeed. Well done every one.

Trustindex verifies that the original source of the review is Google. Excellent service from Eco Energy Windows. We recently got our bathroom window replace, and the service from Gabriela and team was excellent from start to finish. Quick response from first email, and everything took place in less than 3 weeks since first contact. I highly recommend their services.
