0 stars is appropriate but sadly not an option, so 1 star it is. Strap in for War & Peace, it’s a long one. Top tip, pay at least £100 on credit card or use finance. Do not give these people cash because you will never get issues resolved without court proceedings. Even then, you probably wouldn’t get anything back. Started with a cold call at the end of March 2021. Salesman rocked up on 2nd April and did a quote. Install arranged for 6 weeks later. This was delayed a further 2 weeks due to fitter not being available, then again because someone ‘broke panes’ and a 3rd time due to badly welded frames being remade. When they did show up on 4th June, it was 1 fitter sent to install 9 windows and a front door, which would apparently be done in a day. This took him 3 days and the job was not completed. The welds and finish were horrendous, windows weren’t sealed causing water ingress and the front door wasn’t fitted properly, letting water in and was also a security risk as it didn’t latch on the keeps. The only issue eventually rectified temporarily was the front door latching properly so it was more secure. I also had to get a new lock fitted after the fitter kept a key to the front door. They also do not work to building and FENSA regulations, informing me that the side of my house could be supported by a PVC window without a lintel and that lintels are not a requirement above windows. I’ve confirmed with reputable firms that this in indeed incorrect and they should not be trading if they don’t understand basic regs. Exact quote from Mark Leese: ‘re structural changes unless there were issues before the fitting of the windows our engineers are confident that the replacement of windows and completion of brickworks will resolve any bowing etc.’ They did eventually agree to foot the bill ‘as a gesture of goodwill’ and install this after I raised the dispute with the finance company about negligence on their part as the need for lintels should have been picked up by 1st Glass from the initial survey. We asked the surveyor (who also fitted the windows) more than 3 times whether lintels were needed. He said no despite having 20+ years of ‘experience’ in the industry. We were told by the salesman you do not pay until you’re happy with the product. This is a lie. We were threatened into signing the satisfaction form to release the finance even though the job was not finished. It’s a shame you can’t share pictures here because I have well over 100. Nobody in their right mind would sign unless forced to. I contacted the fitter for 4 weeks to come back but no response. I then contacted 1st Glass and spoke to Debbie, who said they would send someone. 4 weeks later, nobody arrived. This was rescheduled and yet again, no show. I then involved the finance company (Shawbrook Bank) in August 2021 and the only way I’m reaching a resolution is after contacting the bank’s CEO who are instructing someone else to do the work that 1st Glass clearly cannot. 1st Glass were due to return yesterday to finish off the job 6 months later. The fitter who did the original bodge job was sent. I had been told by every fitter and surveyor sent by 1st Glass after the install in June, that this fitter had been sacked and was being sued by the company due to issues with so many jobs he had done, costing them a fortune. This was either a lie told by all the fitters or they’re very forgiving. I was given abuse by Ryan on the phone yesterday after asking why this fitter had been sent. He stated that all issues were my fault as I had rushed the job (I left the fitter on my property to crack on over the course of 3 days, uninterrupted in June. I was told the job should have taken a team of 2 men 1 day to complete). A team showed up for 3.5 hours on 17th December, managing to change 3 windows out of 9 and were due to return 18th December but didn’t. Apparently someone was sick but didn’t bother to tell me. I didn’t realise giving someone 3 days to complete a job and then an additional 6 months to rectify it was rushing someone but apparently, they’re the tight timescales 1st Glass cannot work to. Mark Leese (financial director) promises the Earth but cannot deliver. Marcus, the owner, does the same. Nothing but lies come from their mouths and they will twist everything to make it your fault. To top it off, every single fitter who has visited the property after the first install has said they would never have paid for the windows because the quality is that horrendous and would have told the fitter to leave. Shows what the company is like if their own staff haven’t got a good word to say about the quality and their colleagues.
