Critical: Professionalism Hi I enquired about a service with hi spec windows but they advise me too pay cash. Is this what everyone else done. It just sounded slightly suspicious

Had windows and front door changed by Hi Spec, I cannot praise them more highly. From the initial sales meeting to the fitting, everything was perfect. A special mention to the fitting team lead by SB, nothing was too much trouble, they were all perfectionists in everything they did, attention to detail was faultless and a work ethic to be proud of. I will always come back to this company when I need anything. Perfect!

I had all my window and doors replaced. Excellent service start to end. They use good quality products and I would highly recommend their service. A exceptional service by installers SP and Aftaar. They ensured the install was done to the highest standard. Both installers were polite, professional with great work ethics and kept disruption to a minimum.

We have had a new composite front door, windows and back door. Nav took the original instructions and he was a really lovely man who went through all our options and gave good advice. The fitting was done by Harvinder and his colleague. They did a fabulous job, really professional with a good eye for detail. They were extremely courteous and cleared up after themselves. They have really exceeded my expectations and everything looks better than I had envisioned.
