Our Customers Reviews

Don’t take our word for it, see what our clients say

I recently had porch doors fitted by Sovereign Glass. The Price was very competitive. They arrived when they said they would and installed the doors without a hitch. The fitters were very considerate and polite. The doors look very good and have been much admired, the house is certainly warmer. When I Phoned to make the initial appointment I was very satisfied and we created a contract. I had patio and windows fitted the year before . When I hit a hitch with locking the door I phoned and they came within as hour corrected the hinge and explained how to avoid the problem in the future.

After we identified the bifold doors we wanted, Sovereign ordered them form the manufacturer for us and took care of all the paperwork. Their fitters did an expert job and they made sure the doors were properly installed. I would recommend Sovereign without hesitation
