Why do real timber windows require so much maintenance?
Real timber windows require extensive maintenance because wood naturally absorbs moisture, expands and contracts with temperature changes, and degrades when exposed to weather.
Without regular painting every 3-5 years, timber becomes vulnerable to rot, warping, and UV damage. The material’s movement causes joints to loosen and seals to fail, whilst moving parts need frequent lubrication and adjustment to function properly.
The cumulative cost and time investment often surprises homeowners who initially chose timber for its traditional appeal.

The low maintenance benefits of uPVC
Unplasticised polyvinyl chloride (uPVC) eliminates virtually all maintenance headaches associated with timber. The material’s inherent durability means no painting, staining, or sealing requirements throughout the window’s lifespan, which typically extends 20-25 years with minimal intervention.
Resistance to moisture
uPVC window frames resist moisture absorption, preventing rot, mould, warping, and degradation that plague timber alternatives.
Strength & stability
The material’s stability means moving parts continue smooth operation with minimal maintenance.
Energy efficiency
Energy efficiency remains consistently high throughout uPVC windows’ lifespan, unlike timber where gaps and warping can compromise thermal performance.
Resistance to UV exposure
Weather resistance stands as perhaps uPVC’s greatest advantage. The material withstands UV exposure, temperature extremes, and moisture without fading, cracking, or requiring protective treatments that timber demands seasonally.

uPVC window maintenance made easy
uPVC window maintenance requires only basic cleaning materials and minimal time investment. Regular cleaning with warm water and mild detergent is all that’s needed.
Removing loose dirt
Start by removing loose dirt and grime using a damp cloth or soft brush. An old paintbrush works excellently for detailed areas around hinges and gaskets where debris might accumulate. Avoid abrasive cleaners that could potentially damage the surface finish.
Treating stubborn stains
For stubborn stains or discolouration, specialised uPVC cleaner provides effective results without risking surface damage. Apply the cleaner according to manufacturer instructions, typically involving gentle scrubbing with a soft cloth before rinsing thoroughly with clean water.
Removing dirt build-up
Pay extra attention to sills where water and debris naturally collect. These areas benefit from regular cleaning to prevent build-up that might affect drainage or appearance.
Lubricating hinges
Moving parts like hinges require occasional lubrication with appropriate products, but this maintenance occurs far less frequently than timber equivalents. Most homeowners find annual attention sufficient to maintain smooth operation throughout the window’s lifespan.

Should I use a pressure washer to clean my uPVC windows?
We don’t recommend using pressure washers on uPVC windows, despite their durability. High-pressure water can damage or dislodge essential rubber seals and gaskets, force water past weatherproofing barriers, and crack double glazing unit seals. This can lead to moisture problems, condensation issues, and compromised thermal efficiency.
Additionally, pressure washing may strip protective finishes from decorative uPVC surfaces. For safe uPVC window maintenance, use gentle cleaning methods with warm water, mild detergent, and soft cloths to avoid damage.
How often should you clean uPVC windows?
Most homeowners find that cleaning uPVC windows annually or bi-annually maintains excellent appearance and top condition throughout the year.
The low maintenance requirements of uPVC mean that even neglected windows rarely suffer permanent damage from delayed cleaning. Unlike timber, where moisture and dirt can cause lasting harm, uPVC surfaces typically restore to their original condition with appropriate cleaning regardless of accumulated grime.
Seasonal considerations might influence cleaning schedules, with many homeowners preferring spring and autumn cleaning routines that coincide with general home maintenance. However, uPVC’s durability means flexible cleaning schedules won’t compromise window longevity or functionality.
