Professional uPVC door repairs — without replacing the door
Struggling to lock your uPVC door?
Handle stiff, key tight, or the door refusing to lock or budge?
After years of daily use, uPVC door locks naturally wear out. When they fail, it often happens suddenly — leaving your home unsecured or your door stuck shut at the worst possible time.
The good news?
A failed uPVC door lock does not mean you need a new door.
Stephen Fretwell Locksmith specialises in professional uPVC door repairs, restoring your existing door to full working order without the high cost of replacement.
By replacing only the faulty components with genuine, high-quality parts, we can often save you hundreds of pounds, while leaving your door working like new — or better.

Most uPVC doors use a multi-point locking system (MPL). These systems lock the door at several points along the frame for security and help keep the door draught-free.
When new, they work perfectly.
After 10–12 years of regular use, internal components begin to wear, leading to failure.
Common signs include:
✓ Handle becoming stiff
✓ Key is difficult to turn
✓ Door not locking fully
✓ Door stuck, locked or unlocked
Absolutely not.
Stephen Fretwell Locksmith has specialised in uPVC door repairs since 1999.
We repair doors — we don’t sell replacement doors.
Many double-glazing companies claim parts are “no longer available” and recommend a full door replacement. While that can occasionally be true, in most cases we can supply a compatible multi-point locking mechanism that restores — or improves — the original security and performance.
We work with specialist suppliers and have access to one of the largest ranges of multi-point locks available.
By buying in bulk, we secure better pricing and pass the savings directly on to you.
Our fully stocked mobile workshop allows us to complete around 99% of uPVC door repairs on the first visit, meaning:
✓ No unnecessary delays
✓ No repeat call-outs
✓ Your door secured today, not next week
This is a common worry — and completely understandable.
As an experienced locksmith, Stephen Fretwell knows how to open failed uPVC doors safely, without:
✓ Removing the door from the hinges
✓ Taking out glass units or internal panels
✓ Causing damage to the door or frame
Once the new locking mechanism is fitted, your door will operate smoothly and correctly again.
Every repair also includes a full door service and alignment check to ensure everything works as it should.
Often, the lock itself isn’t the original problem.
Over time, doors can become misaligned, making them harder to lock. This adds strain to the locking points, accelerating wear when lifting the handle or turning the key.
As part of the repair, alignment issues are corrected to:
✓ Extend the life of your new lock
✓ Prevent future failures
✓ Improve overall door operation
