Had a new front door fitted. I received a few quotes from different places and these were the best price I got quoted. Had plenty of confirmation of appointments and communication was good. Gary and Reece who were the fitters were extremely polite, friendly and respectful. They kept me well informed throughout the fitting and double checked I was happy before proceeding with the fitting of the joins and seals etc. Left the area spotless. I will be getting more work done with these guys.

Composite Door Fitting

I just had a new composite door fitted by 1st Glass and the whole experience was excellent from start to finish.
I had a home visit within 24 hours on enquiring and the salesperson made sure I was happy with everything before placing the order.
Communication throughout was spot on and it was easy to get hold of someone if I needed to ask questions.
Gary & Reece came to install the door and they were brilliant. The installation was completed quickly and efficiently and they left the area spotless.
The door and hardware excellent quality.
I thoroughly recommend using 1st Glass.

Excellent service, very happy customer!

Had my new windows and doors fitted by installers Gary and Reece who were absolutely amazing! They were both very professional, cleaned up throughout and provided an excellent service. My neighbours are loving the look and admiring the work, better lighting now in my home also since having the doors installed which has made a real difference. I’ve even had a contact in Leeds area who wants to contact 1st Glass. Quality is 10/10. Thank you again.

No Worries

I saw 1st Glass UK advertisement on Facebook and contacted them after checking out the reviews. Mo came out to see us and he was very helpful and we placed an order of 4 windows and 1 front door. We were given a date and Dean, Martin & Kyle turned up yesterday. We couldn’t believe how fast they got on with the job especially as it was really hot and they were in full sunshine. We left them to it and got a call 10 minutes before they finished. We are very happy with the job. Would definitely recommend.

Chose 1st glass for a back garage door…

Chose 1st glass for a back garage door and window we required. 1st visit from gentleman who explained price and how it works and products on offer. Everything I asked for was no problem. Not pushy. Polite respectful and smart. After paying the deposit, 2nd person came to measure up. Again polite helpful and assured us everything we wanted was no problem wanted the door a bit wider to accommodate our twins double buggy so didn't have to take apart in and out. One measured up recieved a call to give instal date. Alex and Paul arrived on time and were polite and respectful. Window and door installed and old one taken away along with any rubbish. Overall whole process I cannot faultone bit. All staff were polite and helpful and did what they assured us they would. Looks perfect and exactly how I wanted it. Will be using again for front door and windows in the future.

Avoid at all cost

Ordered a door and frame in March.
Day before fitting was advised it’s changed to day after
-Door arrived, incorrect fan light
-Fitter ripped out and threw away original Edwardian architrave and damaged plaster work, all without my knowledge or authority
-pieces of plastic architrave were used instead of one for the door trim
-fitter didn’t finish the top of door
-fitter didn’t finish bottom of door
-silicone was used instead of correct sized trim
Complained and advised would be sorted
3 appointments booked, ALL 3 cancelled the day before
Fancy number 2 arrived, wrong again
After 4 months of asking and emailing and calling, I finally had a fitter arrive with correct fan light
Fitter did correct some of the mistakes but my original architrave has been left for me to sort our
Midnight after the last fitter left, I had to evacuate my home due to a massive gas leak. Neighbours had to join me including a child
Complained and asked for my emergency gas safe engineer costs, to be covered!
Promised they would, still waiting for the payment.
Asked for refund, was told they don’t do refunds or compensation
Door is also the wrong colour.
DO NOT USE 1st GLASS UNLESS YOU WANT TO BE LEFT WITH SUBSTANDARD WORK, HOME VANDALISED & OUT OF POCKET

We are whole heartedly sorry for the massive inconvenience this has caused you Katharine, this installation has been a complete anomaly and certainly not up to our usual high standard of work.

To address the plaster and architrave, replacing windows, doors and conservatories is a form of construction and although we are skilled and very carful with how we take out the old products out there's always a certain amount of damage that can be caused to plaster tiles architrave ect. This can be down to the condition and position of the plaster, tiles architrave, we can not be held responsible for the damage to said items as no matter who replaced the windows and doors would come up against the same problem, however in most circumstances our installers are skilled enough to finish the job with the damage to a high standard but again it is down to the condition of the walls/plaster/tiles ect.

As for the payment for the gas engineer we will be covering the cost 100% and i believe our accounts team are working on that as we speak and will have the money with you very soon as agreed.

As for saying your home was vandalised though Katharine is an exaggeration we was there to do a job and unfortunately the job went array mistakes can happen as we have discussed but as you have also stated we came to rectify our mistakes as we always would.

Again we would like to offer our apologies for any and all inconveniences caused and of course any stress this may have also caused it is certainly not our best installation and is 100% a mark on all the good work we carry out on a daily basis.
If you have any issues you would like to discuss with us please give us a call, we would be more than happy to help.

Today we had the front and back doors replaced. We are really happy with the end result. Lee fitted them both, he completed a brilliant job. First class workmanship.
We are really happy with the service and the quality of the doors. We chose this company, because they were so helpful and friendly, we had a lot of help from Lynn, when she came to see us and measure up, there are so many choices of doors. We know that we chose the right company to fit our superb doors.
Thank you to everyone involved.

Good experience but a few hiccups - 3.5 stars out of 5 stars

I'd rate my experience with 1stglass UK as a 3.5 out of 5 stars. Although happy with the outcome, we have dropped 1.5 stars due to the sales process, cost and the discrepancies between the door design and the door we had installed. 

The sales process: We found this a little bit of an odd one. The sales individual who visited our home to discuss our door design was quite firm on both my partner and I being in the room to discuss this and review our choices in the door brochure. We have never dealt with a company who required this so even though my partner was happy for me to decide the door design, he had to come downstairs from his work office to be present in the room. The cost proposed for our composite door design we also thought was a little bit steep (£1,950). I asked if we could think on it but the sales individual stated that this price was only agreed for now and would likely fluctuate if we went back to them in the future. We felt a bit of pressure as a result and agreed on the cost and signed the forms. 

Door design discrepancies: Unfortunately, what we agreed at the final design stage was not what we received when installed. On the day of installation, my partner and I were busy working from home and so we had little interaction or discussion with the installation team. Once the door install was complete, I had to sign some forms and the guys left. We had no complaints about the install as they did a great job but it was only after we had finished work that we noticed that it was slightly different to our agreed design. The dental shelf was missing from the door, the door knob was installed in a different location (I was previously informed this would fit in the centre panel of the door but on the install date informed this would not work/fit correctly and thus had to be installed where the shelf was supposed to go) and the escutcheon door pull was not installed. I contacted 1stglass to make them aware of this. It did take a little bit of time and chasing up to hear back but eventually someone came over to make the changes that they could, but unfortunately these were limited due to some of the permanent install choices (e.g. base of the door knob was not the correct size to be fit in initially agreed location, dental shelf could not/would be complicated to install due to the drilled location of door knob). The front door did also drop slightly after install which resulted in some issues with opening/closing the door but this was fixed when someone visited after my above email.

Overall, we are happy with our composite door. The staff were helpful and open to giving advice, communication for the most part was good but there could be improvements in some areas. I'm not sure if I would use 1stglass UK again due to these hiccups and looking back, we would have looked around for other quotes for comparison. However, we thank 1stglass UK for our door and their work.
