Had 9 windows fitted and a back door over 3 yrs ago and up to know 3 of the windows have failed and look appalling!! The bathroom is stiff to close and can see me having bigger problems in the future ..I have been I touch with 'jason'and arranged for him to come and replace them but he is a no show over 2.500 for this job and one in happy customer..I will be starting proceedings against him in court to either get these fixed or recoup money to do it myself ..stay clear of this company !!

Very pleased with 5 good quality windows and 1door. Professional fitting and top quality finishing inside and out. All cleaned up after and no mess during fitting. Would highly recommend "Darren" and JDL.

Had a stable door fitted and the whole experience has been poor. Almost immediately after installation, the door was letting in a large draught and JDL kept promising that someone would visit to take a look. However, repeatedly no-one showed up. When some-one did finally show up, they washed their hands of the issue, trying to claim that there was nothing they could or would do about the draught. On top of that, the door lock became faulty after a while - and again this is not something JDL are refusing to accept as something they need to fix. I'd suggest you avoid these guys.

Report

Had a brown door and window fitted. Overall experience not great. From day one door needs to be regularly adjusted, you can hear outside noise and feel drafts. 6 months later door lock is loose and doesn't accept key from outside and the door is a nightmare to lock. Won't close properly on a warm day.
Window seems to have dropped and catch now fowls on the frame when closing.
Won't use again.
