Five Top Tips on Maintaining Your PVCu Windows and Doors
PVCu windows and doors are popular across Southport and the Northwest for good reason — they’re durable, energy efficient, and low maintenance. That said, low maintenance doesn’t mean no maintenance.
As any experienced Southport window fitter will tell you, a little care goes a long way in keeping your PVCu windows and doors working properly and looking great for years to come.
Here are our five top tips to help you protect your investment.
1. Clean frames and glass regularly
PVCu frames are easy to clean, but they still benefit from regular care.
Use:
Warm water
A mild detergent
A soft cloth or sponge
Avoid abrasive cleaners or harsh chemicals, as these can damage the surface over time. Keeping frames clean also makes it easier to spot early signs of wear or damage.
Regular cleaning helps prevent issues that could later require attention from a Southport window fitter.
2. Check and clean seals
The rubber seals around your windows and doors play a crucial role in keeping out draughts and moisture.
Over time, seals can:
Collect dirt
Dry out
Become loose or worn
Wipe seals down occasionally and check for cracks or gaps. Catching seal issues early can often prevent more serious problems and costly repairs.
If you’re noticing draughts, it may be worth reading our guide on do I need new windows or can mine be repaired?, as seals are often a simple fix.
3. Keep hinges, handles and locks working smoothly
Moving parts need attention too.
PVCu windows and doors rely on hinges, handles, and locking mechanisms that can stiffen over time if neglected. Lightly lubricating these components once or twice a year can help prevent:
Sticking handles
Misaligned locks
Difficulty opening or closing
If something still doesn’t feel right after lubrication, a Southport window fitter who offers repairs can usually resolve the issue without replacing the whole window or door.
4. Don’t ignore condensation or misting
Condensation on the inside of your home is normal, but misting between the panes of double glazing is not.
This usually indicates a failed glass unit seal. In many cases, the glass can be replaced without changing the frame — something we explain in more detail in Is double glazing worth it?.
Ignoring misted units can affect insulation and visibility, so it’s best to have them assessed sooner rather than later.
5. Arrange professional inspections when needed
Even with good maintenance, there are times when professional advice is invaluable.
An experienced Southport window fitter can:
Check alignment
Identify worn components
Advise whether repairs or replacements are needed
Choosing someone who installs and repairs windows ensures you get honest guidance, not just a sales pitch. If you’re unsure how to choose, our blog how to choose the right Southport window fitter is a great place to start.
Well-maintained windows last longer
