From ordering to fitting there was a only a small delay, I was informed and a new fitting date was set. I did start to get annoyed when I was asked on 4 separate occasions if I wanted to pay up front to reduce the cost, which I refused. I'd suggest you make a note of the customer's response and respect it. The fitting team were great and the door is fantastic

Point very much taken on the recording of the offers given to you it certainly makes sense and we already have in place a management system where notes can be left and recorded, we will be ensuring these are used and not ignored so thank you for pointing that out as we want to make every experience, visit and call a pleasant one and non repetitive.
We would also like to thank you for your patience and understanding throughout the process especially on having to adjust the date you was very gracious throughout.

Amazing job, very very happy

Had 15 windows and a pair of French doors fitted over 2 days by the lovely and professional Mick and Nigel. Absolutely brilliant job by the best 2 fitters we could have wished for. Highly recommend and already getting neighbours asking who did them.

Live up to their name !

Fantastic company to work with, from the home visit that was arranged around us to the install 1st class have been brilliant, we are based in Lancashire and the sales guy came to us on a couple of occasions just to make sure we were happy and even put up with my multiple texts asking questions and replying on a Sunday ! We waited 6 weeks and were kept informed. Gary and Reece did our installation and they were lovely guys, even treated them to a pie from the local bakery for all their hard work ! Thanks so much

No professionalism

Someone named "Lee" called me yesterday having breached data from Instagram and calling me names such us "you are mental". Definitely bad company. Also, I have never filled any forms for this company in response to the below comment.
I would like to hightlight the abusiveness and rasism of the person calling "because you are from Poland you are mental". That is what he said.
And they called me the Instagram name, not Monika then, which is not changing the fact of verbal abusiveness of Lee.

Reply from 1st Glass UK

Hi Monika, If i'm not mistaken you have visited our social sites clicked a request for a price on your windows, filled out your details for the price after which we have then contacted you. You have then told our staff that we shouldn't be contacting you?
How did you expect us to arrange a price if you didn't want us to contact you? makes no sense to me.
No data Breach involved in someone filling a form to request a price Monika which obviously leads to that company getting in touch to arrange the quotation, if anything i'd say that's a company being efficient.

Dealing with 1st glass was a positive experience from start to finish. Lynn who came and discussed the door was so helpful and nothing was too much trouble. The door was fitted by Lee who was courteous, professional and friendly. The door was fitted perfectly and no mess left afterwards. The quality of the door is top notch and I am thrilled to bits with it. I even got my twirly door handles and my door knocker fitted. Would highly recommend

So happy with my new front door ⭐️⭐️⭐️⭐️⭐️

So happy with my new front door, excellent service from start to finish. Very good quality and cheapest I found. Installation was quick and Lee who fitted my door done a brilliant job, and kept everything tidy after he finished,

Will be getting my windows done soon, and wouldn’t go anywhere else!

My neighbour is also using them after seeing the quality and fitting of my door.

Can’t fault this company

I came across this company by chance and were the only company out of three that got back to me straight away as the others didn’t even bother
From start to finish the communication has been excellent and any appointments made were for filled and on time
The fitting team that did our window Ivan Shaun ( Barnsley boys ) were A1 polite friendly and easy to get on with
Thanked us for the waters and ice lollies as the sun was blazing
I have recommended the company to my sister who has now booked to have her windows done with them 👍

Excellent service

From getting a quote, surveyor coming out to measure, communications via WhatsApp and telephone calls to arrange a date to fit French doors, the service has been amazing. Can’t believe how smooth it all went. Would highly recommend this company and would definitely use again if needed in the future. Well done 1st Glass on delivering an amazing service and what a great team you have working for you.

Last but not least a special mention to the fitter Lee. Worked for 4 hours non stop and might I add in this heatwave fitting the doors. Never left any mess at all. Such a lovely man .

Chris and Anthony came to fit my second window from this great company, I had Chris fit my 9ft box bay a few months ago so was very happy to see him again as I know how great at his profession he is. My mum also had her window changed at her home after seeing how great they were fitting the box bay. The staff on the phone are also so polite, I did have a push back on the date for unforeseen circumstances but I was always kept in the picture and was great to have the updates. Both my mum and myself will always happily recommend this company. I've been very impressed, again.

Superb…

We previously had all downstairs doors and windows replaced by 1st Glass last year, so when it came to our two upstairs windows we asked for a quote. Cheapest out of all, however the price doesn’t compromise the quality or service. We had our windows installed yesterday and I can’t compliment Chris and Anthony enough, professional, friendly, clean, they covered everything up including the stairs, bed and carpets, and completely cleaned and tidied up afterwards. Super impressed!! Would absolutely recommend!
