Common Bifold Door Problems And How We Fix Them In Medway


As the owner of TS Glazing here in Hempstead, Medway, one of the jobs I get called out for regularly is bi-fold door repairs. Over the years, we’ve repaired and replaced everything from roller hinges to locks for customers in and across the Medway towns.
Bi-fold doors are a fantastic addition to any home, but when something goes wrong, they can quickly become a headache. Below, I’ve answered some of the most common questions I’m asked by customers about faulty bi-fold doors and shared how we at TS Glazing approach the repairs.
Why do bi-fold door rollers fail?
The top and bottom roller hinges take a lot of strain. They’re constantly carrying the weight of the doors and guiding them smoothly along the track. Over time, the rollers can become worn, clogged with dirt, or even seize up completely.
I remember a job we did in Wigmore, where the customer’s doors had started to grind every time they opened them. The problem was worn rollers. We replaced them with new, high-quality parts and the doors now glide like new.
Can the glass in bi-fold doors be repaired?
Yes of cause it can, a damaged or misted double glazing units in bi-fold doors can be replaced without changing the whole system. Recently, I was called out to Chatham where a homeowner had a large panel that had misted up badly. We swapped out the glass unit quickly, saving them the cost of replacing the entire door set.

What happens when bi-fold door handles and hinges become faulty?
Handles and hinges are another common issue. Handles can become stiff or snap under pressure, while hinges may sag, causing the doors to catch or not align properly. In Rainham, we recently replaced a faulty handle and realigned the hinges so the customer’s doors closed flush again – something they’d been struggling with for months.
Why do locking mechanisms stop working?
The multi-point locking systems used on bi-fold doors are brilliant for security, but they do wear out. Sometimes it’s just an adjustment, but other times the gearbox or mechanism needs replacing.
Not long ago in Rochester, we repaired a locking mechanism that had completely failed. The customer couldn’t secure their home properly, but we had the parts on hand and got everything working the same day.



Do I need to replace my whole bi-fold door if one part fails?
This is a question I’m asked all the time – and the answer is usually no. In most cases, repairing or replacing individual components like rollers, hinges, handles, locks or glass will restore the doors to full working order. At TS Glazing, we pride ourselves on finding cost-effective solutions that extend the life of your doors.
