getting aluminium bifold doors on my extension that I’ve built myself, I’ve been trying to shop around and got a price of about 450ish to fit (on top if the supply price obviously). I’ve never fitted them before, but have fitted a fair few upvc windows and doors, and made and fitted timber door frames etc. How hard are these to fit/risk of c*cking it up or invalidating the warranty or something? Just keen to get a steer from those who’ve done it before. Normally I’d fit it myself and not think twice but a bit cautious about these...
