Professional solutions for all your window and door needs
After 10 years, PVC windows often begin to show signs of wear. The most common problems relate to damaged seals and frames, causing draughts, water leaks and reduced energy efficiency. Specialists also point to visible damage such as cracks or frame deformation, as well as operational issues that make windows difficult to open and close. While these signs may seem minor, they can lead to more serious problems over time.
Draughts
Worn or damaged seals allow cold air to enter, making rooms less comfortable and increasing heating costs.
Water leaks
Weakened seals can let water through the frame, potentially leading to damp and mould problems.
Visible damage
Cracks and frame deformation worsen both the aesthetics and the sealing of the window.
Condensation
Condensation between the glass panes indicates that the seals are no longer working correctly. This reduces thermal insulation and promotes mould growth.
Higher energy consumption
Worn seals and insulation make windows less efficient, causing heating and cooling systems to work harder and energy bills to rise.
Difficulty opening and closing
Due to frame and hardware wear, windows may be harder to open or close, make noises or fail to lock properly.
UV exposure
Older windows without modern glass coatings let through more UV rays, which can cause fading of furniture, floors and carpets.
Blocked drainage channels
The drainage channels at the bottom of PVC windows can become blocked with dirt or debris. When water cannot drain freely, moisture builds up and can cause mould.
Colour changes
White PVC windows may yellow or fade in colour over time due to sun exposure. While this does not directly affect functionality, it reduces the windows' appearance.
Regular maintenance
Clean windows regularly with a mild soap and water solution. Avoid strong products not designed for windows.
Lubricate hinges, handles and locks with silicone grease once a year.
Check and clean seals to keep them supple.
Clear drainage channels of dirt and debris so water can drain freely.
Small cracks can be repaired with a PVC repair kit, and seal problems with sealing materials.
Avoid slamming windows or using excessive force.
Use curtains or blinds to reduce direct sunlight and harmful UV radiation.
Not all faults can be fixed yourself. Contact a window repair specialist if you notice:
Persistent draughts even after seal replacement
Condensation between the glass panes that won't disappear
Difficulty opening, closing or fitting the window in the frame
Cracks, deformation or structural damage to the frame
Signs of damp or mould around the frame
Unusual noises when opening or closing windows
An experienced specialist will quickly identify the cause of the problem, restore the seal and extend the window's lifespan without the need for replacement.
Summary
PVC windows can serve for many years, but after ten years regular inspection and maintenance is essential to prevent minor faults from becoming serious problems. Acting early keeps the warmth in, improves comfort and avoids costly window replacement.
