Nothing assures confidence like reviews from our past customers.

We are very pleased with our new front door. Very good service and excellent quality. Would highly recommend Fenster Glazing.

Nicky Kent

From start to finish, Fenster have been amazing. Great communication, easy to work with, friendly fitters, flawless windows and a very fair price. I’m so happy I chose them over other companies and have already recommended to several of my friends and colleagues.

Dan Alger

Amazing service! Communication was easy from the beginning and both the professional who came to take measures and the one who finally replaced the windows were extremely friendly, quick, and helpful. I can't recommend enough!

Karen Gómez

Laura B

I expected great service from Fenster Glazing based on the Trustpilot reviews and that is exactly what I received. Very satisfied customer, the whole process from measuring to fitting of my replacement door was made as easy as it could be for me! Well done to all in the Fenster team. You deserve your 5 star review.

Mark Vincent Smith

Excellent from End to End. Fenster originally came out to us and went through ideas, a couple of designs and all the options available to us. We settled and then changed our mind on a couple of things which was accommodated without question. Installation was superb - quick and efficient and the final product looks great!!
