Bi-fold doors are good quality although I have since discovered they are pricey compared to competition. Local agent was a nightmare. Initially polite and attentive but logistics and follow through were awful. Surveyor kept going on holiday without passing on details, delays in placing the order as they lost the measurements, the person who described himself as "just the buyer" when I phoned up once day appeared on site a month after the initial measurements had been taken, let himself on site, and tried to retake the measurements before I knew he was there. When challenged about who he was, why he was in on my site without me knowing, what he was doing and eventually why hadn't my windows been already ordered a month before he threatened me and asked me to go in the front room away from the builders so he could "have a word". Never use them and therefore Origin again.
