Very disappointed with our doors. Chose Origin after seeing numerous ads/references in homebuilding mags/Grand designs etc. The windows have only 1 minor fault; there seems to be something non-stainless inside one of the frames that is rusting causing rust coloured water to drain out onto the white render and staining it. Other than that, they are very solid with an engineered feel to them, the opening mechanism is very slick and not a breath of draught gets through. The aluminium doors on the other hand have proven to be a complete waste of money. The front door leaks and the multi lever locks don't engage in 1 or possibly 2 of the lower slots even though the lock slots are adjusted to the max of its range. The rear door leaks pools of water onto the floor when the weather blows rain directly onto it and constantly needs the locks tightening to stop severe draughts. Our previous solid wooden door was more weather proof. The leak appears to be a design fault where water that gets through the seal bridges a plastic spacer (you can see the water trail) into the house instead of running out of the drain. I have approached Origin several times with this; after months they sent out a representative who blamed the fitters saying they were out of tolerance. The fitters came and set up lasers and showed they were adjusted within tolerance and stated it was a design fault. With each blaming each other, Origin have 'offered' to correct the fitment for £350. I thought I was buying a mid to premium product so obviously disappointed I've wasted thousands of £s.
