With a wealth of experience in the glazing industry, all our team members have worked in the industry for many years. We are able to quickly diagnose and repair any bi-folding door issue.
Many common issues include broken rollers, track damage, dry roller bearings, sticking handles, sagging doors and more. We have a wide network of distributers and therefore can secure parts for most doors.
We can also repair glass damage by removing and replacing a glass panel within a bi-folding door.
Bi-folding doors have lower tolerances to work correctly compared to french and sliding doors due to the large number of moving parts. If your door has started to get stiff or is difficult to open, it might be worth a service call from our engineers to look over the doors and see if we can improve the function of your doors.
