Why uPVC Windows Are Low-Maintenance by Design
One of the biggest selling points of uPVC windows is their minimal upkeep. Unlike timber frames, uPVC doesn’t rot, warp, or require painting. That’s a huge bonus for homeowners in Horsham, Crawley, and the surrounding West Sussex areas, where the weather can shift quickly and seasonal maintenance is a hassle most people want to avoid.
Still, a little care and attention can go a long way in keeping your uPVC windows looking great and functioning properly for years.

Routine Cleaning for Frames and Glass
To keep your uPVC windows looking their best, we recommend a gentle clean every few months.
- Use a soft cloth or sponge with warm, soapy water (a mild washing-up liquid is ideal)
- Avoid abrasive creams or chemical cleaners — these can damage the surface
- Pay attention to the frames and sills where dirt tends to build up
- Rinse with clean water and dry with a soft towel to avoid streaks
For residents in more rural areas like Southwater, Mannings Heath, or Lower Beeding — where agricultural dust and pollen can settle on windows — more frequent cleaning may be helpful.
Keeping the Moving Parts in Good Shape
The mechanisms in your windows — such as hinges, handles, and locks — also benefit from occasional care.
- Lightly lubricate hinges and locks every 6–12 months with a silicone-based spray
- Avoid oil-based lubricants which can attract dust and clog the mechanism
- Check screws or fixings are secure and tighten if needed
- Open and close each window fully to ensure smooth movement and airflow
If you’re noticing stiffness or noise when operating your windows, a quick clean and lubrication usually resolves it.
Dealing with Condensation
While modern uPVC windows with double or triple glazing do a good job of minimising condensation, it can still appear on colder days — especially if ventilation is poor.
- Use trickle vents regularly to maintain airflow
- In winter, avoid drying clothes near closed windows where vapour can collect
- Keep kitchens and bathrooms well ventilated with extractor fans
Excess condensation can cause black mould or staining around the frame. Regular cleaning and ventilation are key to avoiding this — especially in older homes around Horsham and Crawley town centres.
Protecting the Seals and Weatherstripping
The rubber seals (or gaskets) around your uPVC windows help prevent draughts and water ingress. To keep them in good condition:
- Wipe down seals gently during your regular window clean
- Avoid sharp tools or scrubbing, which could dislodge or damage them
- Apply a specialist rubber conditioner once a year to maintain flexibility
Well-maintained seals help ensure your windows remain energy efficient throughout the year.
Avoiding Common Mistakes
To get the most out of your uPVC windows, here are a few things to avoid:
- Don’t paint the frames — this can crack or damage the surface
- Don’t use high-pressure washers near seals — they can be forced loose
- Don’t leave faults unattended — deal with draughts or leaks quickly to avoid long-term damage
