So you’ve noticed a cracked window, and you’re wondering whether to repair or replace it. You might be tempted to undertake a repair, but replacing your window is a better long-term solution. Or you might already have your eye on double-glazed units and are ready to call a uPVC window supplier

If you’re currently deciding whether to repair or replace, our handy guide can help.


When to repair your windows


Broken glass

If you have single-paned windows and the glass gets broken, you need to replace it as soon as possible. Broken window panes are inefficient and could be an invitation to opportunistic thieves.


Stuck sashes

Sashes that are difficult to budge can be fixed by replacing the cords and weights. Or you may need to replace layers of old paint that are stopping your windows from opening.


Broken locks

Broken locks need replacing as quickly as possible. Fortunately, you can usually do so without needing to replace the entire unit.


When to replace your windows


Fogging between the panes

When the seals on older-style double-glazed windows fail, water gets in and condenses between the panes. If the glass on your windows looks foggy, then the seals are ineffective, and your window is no longer functioning correctly. 

Broken seals are an irreversible problem that will only get worse over time. However, modern double-glazed units are fully sealed, so a replacement will soon have your interiors feeling snug again.


Structural damage

If you have timber window frames and catch signs of rotten and mouldy window frames early enough, you can repair them. But if the rot takes hold, your windows could be structurally compromised. Even worse, the damage might not be visible to the naked eye, so you don’t know there’s a problem until it’s too late.

If you notice signs of rot or mould around your windows, it’s worth replacing them before the issue becomes a significant problem.


Draughty windows

You can repair some draughts and leaks with silicone or a draught-proofing strip. 

But a window that’s rattling in its frame is no longer doing a good job of keeping the cold weather out. And in most cases, it’s more cost-effective to replace an ill-fitting window than waste money on repairs.


Major leaks

If water regularly seeps in through the area around your window and is causing a damp problem, it’s time for a replacement. You should also check the wall and clear any gutters and downspouts, so water is routed away from your windows.


Repair or replace?


In newer homes, replacement double-glazed units are an energy-efficient solution. Your rooms will be better insulated, so they’re warmer in winter and cooler in summer. As a result, you’ll save money on your energy bills and enjoy additional benefits, including enhanced security, better weatherproofing and a more peaceful interior.

Repairing your windows is obviously a more affordable option. For example, in the case of period properties, you may want to maintain the character of traditional frames. Or you may live in a conservation area where strict rules on replacement windows apply.

However, in the long term, the most effective solution to broken and inefficient windows is to get them replaced. So talk to your uPVC window supplier about suitable styles, colours and finishes for your property.
