Generally pleased with the new door, although there was an anxious moment when the joiners had to build up the door frame with foam and plastic because the opening was too large. The only other issue is a draught coming under the door when there is an easterly wind. It may just need a strip of silicone paste along the threshold. Would I use Cairngorm again? Yes. Your service was professional, your joiners were hard working and answered any concerns that I had, your final product looks good quality, better than Sinclair windows, who I have used in the past. You were cheaper than Norscot, who I have also used in the past. Norscot joiners did a bit of a slapdash job, with poor attention to detail and I had to get one of their workers back again to finish the job to my my satisfaction.
