Great service

Extremely pleased with the work carried out to fit 2 sets of replacement patio doors. John, Jon, Kiran and the team did a great job, everything done skilfully & efficient. We appreciated the tidying up too. Thank you.

Cracked shop window

We had a cracked shop window in Banbury - contacted CN Glass who quoted over the phone and then came the next day to do an accurate survey - the actual quote was significantly less than the phone one, which was a most welcome surprise.

The workmen removed the large pane and returned with the new one. Very clean job (we didn't even shut the shop) and virtually no damage to the old beading and paintwork. Better than we dared hope. Thanks all round for a good job done.

John and Gareth were very kind and reassuring. They informed me of each step of the process for having new windows, they were in communication with me the whole time, very professional and did a very good job. Superb from the both of them.

Pay for a handyman to be at the property because it’s a rental property of mine agreed 1030 appointment no one showed up. I’m paying an hourly rate for my handyman apparently the Glazer is running late and he’s gonna be there at 12. No courtesy call and didn’t want to pay my handyman for the wasted money avoid this company. It’s not relevant that I paid for someone you don’t have the decency to say you would be an hour and a half late 10 mins fine but an hour and a half with no call is a disgrace. Still you will get found out so all good with me

As we said on the phone - before you swore twice at my colleague - we were unaware that you were paying someone to be there and you had asked us to give you half an hour's notice before we arrived. Unfortunately the glazier's previous job had taken longer than expected and he hadn't been able to call us for which we apologised. We have carried work out for you before with out issue so it's a shame you feel the need to tell people to avoid us but to each their own!

I broke a 25 year old tilt and turn double window - well it was caught by the wind …. no spares so had to have a new one - called several including CN Glass - Grant arrived on time quick appraisal (in/out in 20 mins - on the the competitors was still there trying make me sign on the dotted line…. ) quite came in - they understood my dilemma (a window which was not secure) and they managed to come in and replace within 4 weeks …. we have used them previously for 3 outside doors which are also very good - outstanding and friendly service and the clean up afterwards was first class - if 6 stars were available they would have 6 …. thanks a lot

CN Glass fitted replacement double glazed units. It was quick, efficient and no mess. The units look great. CN fitted some other units that had blown a few years ago and they are all still fine.

CN Glass Absolutely a First Class Company

CN Glass is an absolutely a first-class Company if I could give 10 stars I would.

From the start of the process Rob in the sales department came to measure and produce a quote for us. I did ask for the quote to be broken down to individual windows so that I could pick and choose what windows to replace depending on cost. He did that for us and came back with a very competitive price. I was delighted to be able to have the complete house all windows and doors replaced. Then we had a visit from Robert the Surveyor, again very polite and professional he was extremely knowledgeable and because I am disabled took this into consideration with the width of the doors and the reach to open the windows. Elaine the installation manager kept us up to date with what was happening and gave us the installation date with the time the fitters would be arriving.

Window fitters arrived at the time we were expecting they are an excellent team, both Jon and Kieran were, polite, professional & paid great attention to detail. They arrived each morning at 8am and started straight away and worked very hard and very quickly.
Each day they left our home re-cycling free and very clean. We were shown how all the locks worked and if they were a little too stiff, they adjusted them, every feature of our new doors and windows was shown and explained to us, this team were so happy and enthusiastic it was a joy to have them around. In total they fitted 2 large bay windows, 8 windows, 2 doors and the patio doors this only took a week from start to finish.
I am one very happy customer.

This company is second to none.

Amazing job very happy customer.

A company that understands what great customer service should be. From my initial enquiry to the outstanding craftsmanship it could not have been a more pleasing experience. The work covered replacement glass for many windows and the repair of the wooden frames. The work lasted one week. Thank you to the team.
