⭐⭐⭐⭐⭐ Excellent service from 1Glass

⭐⭐⭐⭐⭐ Excellent service from 1Glass – highly recommended

I can’t thank 1Glass enough for the excellent service we received when they supplied and fitted a new front door at my elderly father’s home in Doncaster.

From start to finish, the whole experience was professional and straightforward, and the new door looks fantastic. The quality of the door and the standard of fitting are excellent, and it has made a real difference to my dad’s home.

I also want to give a special mention to the two fitters, Nassar and Qassim. Not only did they do a great job fitting the door, but during their visit my elderly father unfortunately had a fall. Nassar and Qassim immediately stopped what they were doing and came to his assistance, making sure he was okay and helping him when he needed it.

That level of care and compassion really stood out to me. They could have simply concentrated on the job they were there to do, but instead they took the time to help an elderly customer in a difficult situation. Their kindness and professionalism were very much appreciated.

It’s not often you come across tradespeople who provide a great service and show that level of genuine care for their customers.

A big thank you to 1Glass, Nassar and Qassim for the fantastic door, excellent workmanship and, most importantly, for looking after my dad when he needed help.

Highly recommended. ⭐⭐⭐⭐⭐

Everything went so smoothly

Everything went so smoothly from start to finish with great communication throughout. Super happy with the end result and I've had so many positive comments from neighbours already. (Theyre so jealous 😆) Lee our installer was so professional but friendly and went out of his way to make sure we were confident with the entering and leaving process. He did a really good job. I wont hesitate to recommend or use your company again in the future. Thank you so much.

Had a new front door fitted

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.
