Double Glazing Repairs in Canterbury, Kent
Fixing Misted and Foggy Glass Units
One of the most common issues with double glazing is misted or fogged-up windows. This happens when the seal between the two panes of glass fails, allowing moisture to build up inside. While some companies may recommend replacing the entire window, that’s rarely necessary. At Castle Locksmiths, we can replace just the glass unit itself—keeping your original frames intact and costs much lower. We use high-quality sealed units to restore clarity and insulation to your windows, making them look and perform like new again.
Misted windows not only affect the appearance of your home but can also lead to heat loss and higher energy bills. Our team will measure, source and fit new units quickly and efficiently, with minimal disruption to your home. Whether it’s one window or several, we provide a straightforward, honest service that brings your double glazing back to life.

Repairing Handles, Locks and Hinges
Over time, double glazed windows and doors can develop mechanical issues. You might notice a stiff handle, a faulty lock that won’t engage, or a hinge that causes the window to catch or not close properly. These problems not only make everyday use frustrating, but they can also compromise your home’s security. At Castle Locksmiths, we repair all common double glazing hardware faults. Whether it’s a jammed window lock, misaligned hinges, or broken handles, we carry a wide range of replacement parts to get things working again.
We also specialise in uPVC locking mechanisms and multipoint door systems, offering on-the-spot repairs for most common faults. Our work is clean, tidy and carried out with care. You don’t need to replace the entire unit when simple repairs can solve the problem. Our goal is always to restore full function to your windows and doors without unnecessary costs.
Improving Kent Security with Upgrades
While double glazing provides insulation, older window and door mechanisms may not offer the same level of protection as modern systems. If you’re concerned about security, we can upgrade your existing double glazed units with stronger locks, anti-drill cylinders, and more secure handles or restrictors. This is particularly important for ground floor windows, older patio doors or conservatories where opportunistic break-ins are more likely. Castle Locksmiths can assess your current window and door security and recommend practical upgrades that don’t require full replacement.
We work with a variety of window types, including uPVC, aluminium and composite frames, fitting British Standard compliant locks where possible. We also offer child safety restrictors for families with young children, giving you extra peace of mind. These simple enhancements not only improve your home’s safety but can also be a plus when it comes to insurance compliance. Our approach is straightforward—real improvements that make a real difference.

Frequently Asked Questions
Can I fix a misted double glazed window without replacing the whole frame?
Yes, absolutely. A misted double glazed window occurs when the seal between the panes fails, allowing moisture to seep inside. While it might look like the entire window unit needs replacing, that’s rarely necessary. At Castle Locksmiths, we specialise in replacing just the sealed glass unit, not the full frame. This keeps costs much lower and avoids major disruption to your home. We’ll carefully measure the affected unit, order a high-quality replacement, and fit it quickly and cleanly. Your frames stay in place, and your window will look as good as new. The new unit will also restore proper insulation and visibility, making your home more comfortable and energy-efficient. Whether you have a single failed unit or several misted panes across the property, we can sort it out with minimal fuss. It’s one of the easiest and most cost-effective ways to restore your double glazing.
Do you repair window and door locks on uPVC frames?
Yes, we do. Many of our double glazing repair callouts in Canterbury involve fixing or replacing faulty uPVC window and door locks. Over time, mechanisms can become stiff, jammed, or simply stop working altogether. This is especially common in multi-point locking systems used on uPVC doors and windows. At Castle Locksmiths, we carry a wide selection of replacement parts and are trained in repairing all major locking systems. We can often fix the problem without replacing the entire unit, saving you both time and money. Whether your window won’t shut properly, the handle has snapped off, or the key no longer turns in the lock, we’ll diagnose the issue and sort it quickly. A properly functioning lock is essential for both home security and insulation, and we take every job seriously. All repairs are carried out with care and precision, using quality components that are built to last.
How do I know if my windows need repairing instead of replacing?
In many cases, double glazed windows and doors can be repaired rather than replaced—especially when the frames are still in good condition. Common issues like misted glass, draughts, faulty locks, broken hinges or handles can all be repaired by an experienced professional. At Castle Locksmiths, we’ll carry out an honest assessment of the problem and advise you on the most practical and cost-effective solution. We never push for full replacements unless they’re absolutely necessary. If your windows open and close properly and the frame is sound, then repairs will usually be more than enough to restore both appearance and performance. Repairs are not only cheaper than full replacements, but also quicker, less messy, and far less disruptive to your home. We aim to get things working like new again, saving you the expense and stress of replacing everything when a targeted repair will do the job perfectly.
Can you help improve the security of my windows and doors?
Yes, security upgrades are an important part of our double glazing repair service. Older window and door systems—especially those installed more than 10 to 15 years ago—often don’t meet today’s security standards. We can upgrade window locks, door cylinders, and handles to improve both safety and insurance compliance. Castle Locksmiths fits modern multi-point locking mechanisms, anti-snap cylinders, and secure handles that offer much greater resistance to forced entry. We can also add child safety restrictors or window locks for extra protection in family homes. These upgrades don’t require full window or door replacements, and we work with both uPVC and aluminium frames. After an assessment, we’ll talk you through simple, effective changes that can make a big difference to your home security. Whether you’re looking for added peace of mind or have recently experienced a break-in, we’ll help you make your property more secure without overspending.
How much does double glazing repair cost?
The cost of a double glazing repair depends on the nature of the problem and how many windows or doors are affected. At Castle Locksmiths, we keep our pricing fair, transparent and competitive for homeowners and landlords throughout Canterbury. Common repairs like misted glass replacement or handle and hinge fixes are often more affordable than people expect—especially compared to full window replacements. We don’t charge call-out fees, and we’ll always give you a clear quote before starting any work. Because we carry many parts with us, we can often complete the job on the same visit, which helps reduce costs even further. Whether you have a single issue or several windows that need attention, we’ll advise you honestly on the most cost-effective way forward. Our aim is always to repair rather than replace, saving you time, hassle and money while restoring comfort, security and appearance to your home.
