Your uPVC windows are durable, but over time, your handles can loosen, your screws can strip, and your square bar spindles can become worn down.

That’s where our uPVC window locking system repair service helps.

We’ll do the following:

• Tighten or replace loose handles and screws
• Fix or realign the locking system
• Check and adjust the frame for smooth operation
• Replace worn parts like the espag or spindle
• Test the fix and ensure good working operation
• Run you through all the options that you have
• Remove the old parts or pieces
• Remove all of our rubbish

We also work on uPVC door locks. If you’d like more information on our uPVC door lock services, head over to our door locks pages.

One common issue we find on older uPVC windows is a worn espagnolette lock, or espag lock. This can cause your window handles to turn, but your window is stuck, either it doesn’t either lock or open.

We offer espagnolette window handle replacement for all handle types and finishes.

When we’re done, you’ll have:

• A properly fitted handle
• A working locking mechanism
• Smooth opening and closing
• Restored security

You’ll feel the difference right away, no more wobbly handle or half-turn that doesn’t catch.

Depending on the cause of the issue, we follow simple steps, than avoid the need for you to replace a window lock. Once we’ve arrived at your location and resolved your issue, we’ll even give you tips on maintaining your newly working window. Don’t hesitate to ask, as professionals, we enjoy giving this advice the majority of the time.

Depending on what sort of home you have, you may have cockspur handles, which are common in older homes and aluminium frames often feature them. They’re simple, reliable, and still very common around Kensington and Earls Court but over time, the latch or screws can wear out.

If your cockspur handle feels loose or won’t lock, we’ll come out and take care of it. Our cockspur handle repair includes:

• Removing the old handle
• Checking for damage around the frame
• Installing a new handle that fits perfectly
• Testing everything before we leave

We can usually match your existing handle style and colour too, whether it’s chrome, white, or antique brass.

If your double-glazing window won’t stay closed or the handle spins freely, the internal locking mechanism is probably damaged.

Our double-glazing window lock replacement service is ideal for windows where the internal gearbox or espag lock has failed. Sometimes, it’s just a worn screw or bent square bar, but other times, replacing the full unit makes more sense.

We’ll explain exactly what needs doing before we start. You’ll get clear pricing, a quick turnaround, and a secure, smooth-closing window when we’re done.

Every week, we help locals with the same recurring window issues. You might recognise one:

• Handles that spin or wobble
• Stuck espag locks that won’t move
• Frames that don’t line up properly
• Screws that have dropped out
• Windows that won’t fully close or open

If any of that sounds familiar, it’s worth giving us a call. You’ll save yourself a bigger repair cost later, and you’ll know your home is properly secure.

With us, you’ll get a professional locksmith who arrives up on time, checks the whole locking mechanism, and makes sure your window opens and closes smoothly again. Most repairs are done the same day, you’ll be surprised how quick it is.
