Windows replaced
Had four windows replaced, two upstairs and two on the ground floor. Replacement was expected to take all day and fitters Martin & Harry worked outside in very rainy conditions without complaint and never stopped, except for two brief cups of tea!
The wet weather meant they had to return the next day to finish off and they arrived on time as promised, did an excellent job and cleared everything away before leaving. I was very happy with the service from CN Glass

Very pleased with both experience and outcome
I was amazed at how quickly and efficiently the work was done and am very pleased with my new doors. The workers were polite and considerate of the property and left it spotless. The company was also very helpful during the process of deciding what doors to get. Very pleased with the experience and the outcome!

Rob, did an excellent repair job and the door is working better than ever before. Absolutely thrilled with the result!

Proper customer service
A rare thing these days to find a company that actually answers phone calls, responds to emails within hours, if not minutes, and basically does what it says it's going to do. Not just a single salesman, but right through the process with every member of the team. Even when there was a small issue, they took ownership and resolved it quickly and effectively. I have no hesitation in recommending CN Glass, and would certainly use them again. Frankly, I can't remember the last time that happened.

Cat Flap
The product was not fit for purpose. The laminated pane was cracked within 2 weeks of installation. The flap was ineffective. I have written off £649.96 and gone to a different supplier who will provide a panel that has toughened glass on both panes with cat flap for two-thirds the price.

Good morning C TJ,
As per the email I sent to you on 4th August in response to your email asking us to respond before you posted a review... we had to use laminated glass due to the new build regulations, you mention that your different supplier has used toughened glass instead which doesn't comply with these regulations. As I also explained we would have replaced the unit free of charge as a good will gesture. In your own words "I don’t think the flap works due to the position of the chip in my cat" so I don't think the flap can be called ineffective.
Excellent service
Excellent service, very helpful and fast. Reasonable price and lovely guys who came out to measure and fit.

Excellent work
This is not the first time we have used CN Glass to replace our double glazed units and I am so pleased to have made that decision. Their work was exemplary, very tidy and such a friendly team both in the office and the guys who visited our house. Would certainly use them again.

Reglazed a large church-style window.
CN Glass re-glazed a large church-style window with quite difficultly-shaped double glazed units. We are very pleased with the quality of the work and also for the friendly, courteous and professional manner of the installation team and the efficient and timely communications from the office staff.

Very pleased
Very pleased - good communication via email, appointments arranged in a good timeframe, two visits (one to measure, one to install) done by different people who were all friendly and efficient. The installed double glazing + cat flap is great.
