How Do Double Glazing Locks Work?
On a double glazed unit, the locking mechanism is contained in the window’s handle. When you turn the handle, the uPVC window gearbox which is attached to it pushes shootbolts and roller locking cams into the furthest corners of your window frame to lock it and protect your entire window.
Although it’s not a common issue, a double glazing locking window handle can break. But most commonly, it’s the case that the handle just needs some adjustment because of natural wear and tear and the accumulation of dirt, debris or corrosion over time. You may not need a new window lock. Just some work to allow smooth operation again.

What happens if the window lock is stuck?
If your window lock is stuck, then this is a bit more of a tricky challenge. The same applies if you have a broken key in the lock. You’ll need to get yourself a replacement handle with a new lock from an online shop; the majority of hardware suppliers have them. Choose a reputable supplier many of which will have a locking mechanism buyer’s guide to help you.
You’ll need to cut the handle to size so it fits before screwing it in place on the window and making sure it works. Unless you have good DIY skills, it’s more than likely you’ll need to get a professional in to have a look at the uPVC hardware, someone with the right skills for replacing window locks.
Because a working window lock is paramount for security and insulation, it’s worth checking all the double glazing locks regularly. If at any point you are suspicious of whether the locks on your windows are still working, you can give them a gentle test from the outside to make sure they don’t come away easily. If you can move them, then so can a potential intruder! A little tug from the outside with the window fully locked should be enough to make sure.
Another red flag for failing window locks is if you feel a draught coming through one of the windows. If you’re sure that the double glazing hasn’t blown, it might be good to check that the window is shutting correctly and has the proper alignment.
Seek advice from an expert if you are struggling with window lock repair, maintenance or replacement.

FAQs
How regularly should I check my double glazing window locks?
It’s recommended to test your window locks at least once a year to ensure they’re functioning properly and to become aware of any problems. The importance of this cannot be overstated especially if you live in an area with high crime rates.
Can I update a broken double glazing window lock myself?
When it comes to maintaining window locks, most homeowners can manage minor jobs like tightening up a loose handle. However, you are always best advised to seek advice from an expert for serious locking mechanism faults or other issues which comprise the security of your uPVC windows. These include a broken window, a broken key in lock, unlocking a uPVC window that’s jammed, or installing uPVC window locks on new double glazing. Dismantling the locking mechanism is always a job best left to the experts.
What are the signs that my double glazing window locks need repair or replacement?
Watch out for a loose, unfastened or wobbly handle, a stuck lock, or an unexplained draught coming from the window frame even when the window is closed.
How much does it normally cost to replace a double glazing window lock?
The price of replacing a window lock can vary depending on different factors like the type of lock, how bad any damage is, and the amount of labour required. On average, you can expect to pay between £100-£200 to fix a uPVC window lock. However, a simple window lock repair will cost much less. If you just need a new lock then you may be able to do this yourself.
Can a defective double glazing window lock compromise the thermal efficiency of my home?
Yes, if the window cannot lock correctly, it will allow draughts to enter your home, lowering its thermal performance and increasing your energy bills. Ensuring your window locks are functioning well will help preserve your home’s energy efficiency and keep costs down.
How can I look after my windows to ensure a functioning window lock mechanism?
When you clean the windows, you can open them away from the frame to expose the window lock mechanism. Gently clean the exposed areas and frame with a soft brush or feather duster. If you are cleaning the glass with a soft cloth and mild detergent, then don’t use this on the locking mechanism as this can trap dirt particles and tiny pieces of debris and could interfere with the lock.
