Caring for your home isn’t just about keeping it looking its best—it’s about protecting your investment and ensuring everything functions exactly as it should. When it comes to your windows and doors, proper care can significantly extend their lifespan and efficiency. In this guide, we’ll walk you through everything you need to know about uPVC window and door care, from simple maintenance routines to tips on maximising energy performance. With the right approach, you can enjoy secure, weatherproof, and stylish installations for decades.
Understanding uPVC materials
uPVC—short for unplasticised polyvinyl chloride—is a modern, low-maintenance material well suited for windows and doors. One of the key advantages of choosing uPVC is its long-lasting nature. Unlike wood, which can warp and rot, or aluminium, which may suffer from thermal bridging, uPVC is both weather-resistant and thermally efficient, making it a popular choice in British homes.
According to the uPVC Institute, with proper care and maintenance, uPVC windows can last up to 40 years—far longer than traditional timber frames. That’s not just good news for your home’s aesthetics; it also means fewer replacements and better long-term value. At Cathedral Windows, we’ve specialised in these solutions for over 30 years, and we’ve seen first-hand how proper upkeep can preserve both function and style.
Regular cleaning routines
Establishing a regular cleaning routine is key to maintaining your uPVC windows and doors. Use a mixture of mild detergent and warm water to clean the frames and glass. Steer clear of harsh chemicals and abrasive sponges, as these can cause scratches and dull the surface over time. Instead, opt for a soft cloth or sponge and rinse with clean water for a streak-free finish.
To keep everything looking fresh and ensure operation stays smooth, we recommend cleaning at least once every quarter. This simple step not only rejuvenates their appearance but also helps to spot any developing issues early—such as dirt build-up around seals or opening mechanisms.
Inspecting seals and fittings
Keeping an eye on your window seals and door fittings is another essential part of uPVC window and door care. Seals serve as the first line of defence against drafts and moisture. When they begin to degrade, you may notice a drop in thermal performance or even signs like condensation inside the double glazing.
Check for visual cracks in rubber seals or listen out for unusual creaks and whistles when windows are opened or closed. Also take a moment to inspect hinges and locks—signs of rust, stiffness, or looseness could indicate they need attention. Luckily, regular checks can prevent small issues from turning into major repairs and help preserve your windows’ weatherproofing capabilities.
Addressing problems promptly
Even with regular care, issues can arise. Common problems include misaligned frames, stiff locks, and failing seals. Left unchecked, these can begin to affect energy efficiency and security. Addressing them early is always the most cost-effective solution—waiting until a problem escalates often leads to higher repair costs or even full replacements.
While some DIY maintenance tips can be helpful—such as oiling hinges or replacing minor seals—complex issues are often best left to the professionals. Our team at Cathedral Windows is here to offer not just expert craftsmanship but also reliable aftercare, ensuring your installations are always performing at their best.
Enhancing energy efficiency
Good maintenance does more than just preserve appearance—it actively improves your home’s energy performance. Well-maintained windows and doors keep warm air in and cold air out, helping you save on heating bills and make your home more eco-friendly. In fact, the Energy Saving Trust reports that up to 30% of heating energy can be lost through drafts and poorly sealed openings.
By looking after your fittings, cleaning the frames, and protecting seals from wear, you help reduce heat loss and maintain consistently high thermal efficiency. Over time, that translates into meaningful savings and a more comfortable indoor environment for you and your family.
