How to Maintain Your UPVC Windows and Doors for Decades of Use

Posted by | July 30, 2025

One of the major appeals of UPVC is how low-maintenance it is. But "low maintenance" doesn't mean "no maintenance" a few simple practices can extend the lifespan of your UPVC windows and doors well beyond 30 years.

Routine Cleaning

Use warm soapy water and a soft cloth to clean the frames every few months. Avoid abrasive cleaners or scouring pads as they can scratch the surface and damage the protective finish.

Did you know? The glossy finish on quality UPVC resists UV fading for over 20 years with minimal upkeep, keeping your windows and doors looking fresh.

Inspect Seals and Gaskets

Seals and gaskets are essential for thermal insulation and weatherproofing. Clean them gently with a damp cloth to remove dust and dirt, and check regularly for any signs of wear or damage.

Replacing worn or damaged seals early can prevent draughts and condensation, helping maintain energy efficiency.

Lubricate Locks and Hinges

Locks and hinges should be lubricated at least once a year with silicone spray or light oil to ensure smooth operation and prevent rust.

Did you know? Proper lubrication can extend the life of mechanical parts by several years, reducing the risk of costly repairs.

Check Drainage Holes

UPVC frames include built-in drainage channels that allow rainwater to escape. These holes can sometimes become blocked by debris or dirt.

Regularly inspect and clear drainage holes to prevent water from pooling inside the frame, which can cause damage over time.


Regular care ensures continued performance, avoids costly repairs, and maintains your home’s energy efficiency. A little attention now saves a lot later, making UPVC windows and doors a truly hassle-free investment.
