First rate
We're in the process of renovating and have been visited by Zenith, who were highly professional and patient. We were very impressed and highly recommend considering them for your project.
Mr Hawthorne
Outstanding service
Zenith came by recently and gave me a really good price on the windows I was thinking of changing. They gave me a solid price compared to what I've heard my friends paid and left me with a really good impression. Outstanding service.
Mr Vornicu
Best price I've received
Zenith were really professional and offered me one of the best prices I've received for my renovation plans. The price offered was really fair - keep up the good work.
Ms Coleman
Polite and friendly
Zenith visited today to discuss a replacement patio door - as expected, they were polite and friendly. We've been through the whole process and I have placed an order. As a previous customer, I expect to be fully satisfied with the final installation.
Mr Sixsmith
Can't ask for more
I met the most polite sales person you could encounter. He walked me through the offer in a professional manner and got me a good deal versus what I found elsewhere. Excellent people skills and great value.
Ms Kovalski
Really good service
Having shopped around for quotes, everything we found on the market seemed overpriced and we almost gave up. Zenith visited and presented us with the best deal we'd came upon so far. Would happily recommend Zenith to my friends.
