AGG - Allerton Glass & Glazing Ltd

Great company and great aftercare. We had a Rockdoor fitted last year and after a while it needed a tiny bit of adjustment and they were back out in a heartbeat. Sorted the issue, cleaned the door up and encouraged me to contact them with any little issues in the future so they don't become big problems. A very refreshing approach to customer service. I'd highly recommend them if you want a high quality product and to be looked after once it's fitted

The two guys who rebuilt our conservatory in accoya wood did a marvellous job with a keen eye for detail. They were very tidy and chatty. Huge thanks to John-Paul for his design and advice. We wouldn't hesitate to use the company again.

I just wanted to say a huge thank you to Allerton Glass & Glazing. They originally fitted my UPVC double glazing 33 years ago, and even now in 2026 they still look fantastic and are going strong — a real testament to the quality of their work. I recently got back in touch after a contractor working next door accidentally broke my living room transom window. The team at AGG were brilliant from start to finish. Neil did an excellent job with the replacement, and I’m very grateful to Hannah, Jess, and Tom for all their help and professionalism throughout. It’s rare to find a company that delivers this level of quality and service over such a long time. Truly, you get what you pay for.

AGG fitted patio doors and some windows way back in 2017/18, they looked great and greatly improved the access to the garden (and still look good). After years of use,I was having difficulty locking the doors. I called AGG and talked to the very helpful Hannah, and she quickly arranged for the fitters ( two very skilled lads ) to come around to my house. The problem was the adjustment of the doors and not the locks. The job was completed in a couple of hours, they now lock perfectly. The doors are still in warranty, so NO charge. Great after sale service from AGG. Thanks to everyone at AGG.

We have just recently had all our windows and doors replaced by AGG. 9 windows and 2 doors, plus we had soffit, facia, gutters and tudor boards replaced at the same time. The lads did a fabulous job and we are so happy with the end result. We opted for triple glazed units and for a small fraction of the total cost from double glazing, we have already noticed a huge difference in noise reduction and heat retention. I would highly recommend this company to anyone looking for quality windows and doors expertly fitted. I am aware this company has been operating for years and is a local mainly family run business. Which I prefer to using national companies who just want your dosh. Thanks to jess , john paul and the whole gang for an excellent job.

Highly recommended - I have to say from start to finish it was a pleasure to deal with AGG Allerton Glass & Glazing. Having had a few quotes firstly there were spot on with the price, and no pushy sales team trying to push to hard. Once we agreed the spec of the doors and price the ordering process was straight forward with great communications. The surveyor came out about a week later and he was efficient and really helpful and polite. Today the doors were fitted and the lads were amazing, shout out to Josh and Callum for being really professional, friendly and most important really good at their jobs. The doors look amazing and we are really pleased. No hesitation of recommending AGG to anyone looking for windows and doors and any of the services they do in the Merseyside and North West areas. 5 Stars 🎖️🎖️🎖️🎖️🎖️ Mr Robinson, Belvidere Road, Crosby L23

We are very happy with our new door, which has just been fitted today. From start to finish, dealing with AGG has been seamless. The guys who fitted the door took a lot of pride in their work and did a great job, thanks Callum & Josh. I would definitely recommend this company and use them again in the future.
