How to Maintain Your uPVC Windows and Doors for Long-Lasting Results

One of the biggest selling points of uPVC windows and doors is how low-maintenance they are. Unlike wood, which needs regular painting and sealing, uPVC is weather-resistant and easy to care for. But to get the most out of your investment, a little routine maintenance goes a long way.

At Regency Home Improvements Ltd, we’ve fitted thousands of uPVC windows and doors across Deal, Kent — and we always recommend following a few simple steps to keep them in top condition for years to come.

Here’s our expert guide to maintaining your uPVC products and protecting your home.

1. Regular Cleaning

uPVC frames don’t require any special treatments, but cleaning them a few times a year helps prevent dirt build-up and staining.

How to clean uPVC windows and doors:

• Use a soft cloth or sponge with warm, soapy water

• Avoid abrasive cleaners or scourers that could scratch the surface

• Rinse thoroughly with clean water and dry with a microfibre cloth

Top Tip: For tough marks or mildew, use a specialist uPVC cleaner or a mixture of vinegar and water. Avoid using bleach or solvent-based products.

2. Clean and Inspect the Glass

Keep your double glazing sparkling by wiping the glass with a glass cleaner or vinegar solution. This not only improves appearance but helps you spot any signs of condensation or seal failure.

Check for:

• Moisture trapped between panes (a sign of failed units)

• Chips or cracks

• Excessive condensation inside the room

If you notice any issues, our team can help assess whether repairs or replacements are needed.

3. Lubricate Locks and Hinges

To keep your windows and doors opening and closing smoothly, apply lubricant to all moving parts at least once or twice a year. This includes:

• Hinges

• Handles

• Locks

• Latches

Use a light silicone spray or a dedicated lock lubricant — avoid oil-based products like WD-40, which can attract dirt.

Bonus Tip: Tighten any loose screws during this check to keep everything secure.

4. Check Seals and Weatherstrips

Over time, the rubber seals and weatherstripping around your frames can become worn, brittle, or detached. These are essential for keeping out draughts and moisture.

Inspect your seals for:

• Cracks or tears

• Gaps or lifting

• Discolouration or brittleness

If any issues are found, the seals can usually be replaced quickly and affordably, restoring your window or door’s energy efficiency.

5. Keep Drainage Holes Clear

Most uPVC windows have small drainage channels at the bottom of the frame to allow water to escape. If these become blocked, water can build up and cause damage.

Every few months:

• Check for debris like leaves, insects, or dirt

• Clear blockages using a soft brush or small wire

• Make sure water can flow freely through the weep holes

6. Inspect Door Alignment

If your uPVC door becomes difficult to lock or scrape against the frame, it could be out of alignment. This can happen over time due to weather changes or usage.

Our team at Regency Home Improvements Ltd can adjust hinges, re-align the door, or check for signs of frame warping.

7. Repainted or Refreshed? Be Careful!

Thinking of giving your frames a fresh colour? Be cautious — not all uPVC can be painted without affecting its finish or warranty. We recommend consulting a professional or choosing coloured uPVC products from the start for the best and most durable look.
