Patio Door Rollers Replaced in Newcastle

The sliding leaf of a patio door rests on a pair of roller carriages, one at each end of the bottom edge. Each carriage has one or more wheels that run on a raised track. The leaf is heavy because of the large glass unit, so those wheels carry a lot of weight every time the door moves.

Over time the wheels flatten, their bearings wear, or grit from the track gets ground into them. A cracked wheel can then cut into the track, making the door worse with every use.

The leaf has to come off the track, which takes two people because of the weight of the glass. With it out, we remove the old carriages, check the track for wear or damage and clean it out. New rollers of the right size and type go in, the leaf goes back, and we adjust the height so it runs level and sits square to the frame.

Setting the height properly matters as much as the new wheels. It is what makes the door seal evenly and brings the lock back in line with its keep.

Worn rollers often show up first as a lock problem, because a sunken leaf leaves the hooks below the keep. If the door slides freely but still will not lock, the fault is more likely in the lock itself; see patio door lock replacement. We check both on the same visit so you are not paying for the wrong part.

Most roller wear starts with dirt. Vacuum the bottom track regularly and wipe it with a damp cloth, and avoid oil on the track because it holds grit. Our guide to patio door sliding problems covers other simple checks before you book.

The existing range for patio roller replacement and realignment is around £120 to £250, depending on the number of rollers and the weight of the door. The price is confirmed at a free in-person quote. Telling us the width of the door and whether it is uPVC or aluminium helps. For aluminium sliding doors see also aluminium window and door repairs.
