A Few Tried & Tested uPVC Window Maintenance Tips

Keeping your uPVC windows healthy is not rocket science; you just need a short, dedicated routine.

Below are practical uPVC window maintenance tips we have compiled from installers, homeowners and AIS Windows technicians who see both the good and the bad every day.

• Start with a Quick Vacuum: Grab the soft-brush attachment and run it along the tracks, corners and rubber seals. This lifts out loose dust, dead insects and other particles present in the frame’s grooves.
• Wash with Warm, Soapy Water: Fill a bucket with lukewarm water and a mild dish soap, avoiding harsh or abrasive products. Dip a fresh microfibre cloth, wring it out slightly and wipe the frame from top to bottom. Change the water as soon as it looks dirty to avoid covering the surface with grime and water streaks.
• Glass Inside First, Outside Next:
  

  • Interior Panes: Once a month, spray it with a non-smear glass cleaner or a 50-50 mix of water and white vinegar. Polish in small circles with a lint-free cloth, chasing every corner to ensure crystal clear views.
  • Exterior Panes: Every two to three months, use a bucket, fresh soapy water and a sponge without grit. Work in gentle circles, then pull a squeegee from top to bottom. Finish with a dry microfibre cloth around the edges to remove any water spots.
• Treat the Hardware with Care: Apply a light coat of oil or silicone spray to the handles, hinges and locks twice a year (WD-40 is a suitable alternative). Open and close the sash a few times to allow the lubricant to spread evenly, then wipe away any excess drips. Also, tighten loose screws with a small screwdriver.
• Respect the Seals: Those discreet black or grey gaskets keep drafts and rain outside. Check them during cleaning; if a segment looks brittle or lifts when you tug, book a quick replacement. A healthy seal can save money.
• Don’t Panic Over Seasonal Swelling: uPVC expands a little during peak summer heat and contracts in winter chill. If a window feels stiff on a scorching day, wait for the evening cool-down before forcing it. Proper installation, something AIS Windows prides itself on, allows this natural “breathing” without long-term warping.

Types of uPVC Windows You Can Choose

• Casement Windows swing out like a door, catching every passing breeze. They are perfect for living rooms, bedrooms, kitchens or anywhere you need fresh air while keeping street noise out.
• Fixed Windows do not open, but they make a big statement. They are huge clear panes that pour daylight down staircases or across lounge walls while framing the view like a picture.
• Tilt-and-Turn Windows offer two moves in one frame. Tilt the sash at the top for gentle ventilation, or swing it inward for a wider opening that is handy for cleaning or quick ventilation. Their versatility suits studies, balconies, bathrooms and any room that multitasks.
• uPVC French Windows come as an elegant pair that pushes inward or outward, leaving no post in the centre. The result is unbroken panoramas and a constant breeze, perfect for kitchens or bathrooms that deserve a touch of style, extra security, peace of mind and comfort every day.
