Turning the handle on lift and slide doors causes their panels to be lifted onto the rollers, so they can be opened or closed. However, if a faulty handle is stopping them from being lifted onto the rollers, we can repair or replace the handle if necessary.
Older lift and slide doors are renowned for their unreliable gearing and components, so operation difficulties are quite common with them. But regardless of what is making your lift and slide doors hard to operate, we specialise in their repair, so we are sure we can help.
