Essential Window Maintenance Tips

Clean Windows Regularly

Cleaning uPVC window frames with a cloth for proper maintenance.

Dirt and grime can affect appearance and performance. Use a mild detergent with warm water to clean glass and frames. Avoid abrasive cleaners that could damage protective coatings.

Tip: A microfibre cloth ensures streak-free glass.

Check and Lubricate Moving Parts

Applying silicone lubricant to a window hinge to ensure smooth operation.

Over time, hinges and locks can become stiff, affecting operation. Apply a silicone-based lubricant every 6–12 months to keep moving parts in good condition.

Tip: Regular lubrication prevents rust and extends the life of window hardware.

Inspect Window Seals

Inspecting rubber seals on a window to prevent draughts.

Seals play a crucial role in window and door maintenance by preventing draughts and moisture penetration. Check for cracks or wear and replace damaged seals to maintain insulation.

Tip: If you feel a draught even when windows are closed, faulty seals may be the cause.

Test Locks and Handles

Loose or broken locks and handles compromise security and usability. Test them regularly to ensure they operate smoothly.

Solution: Window Fixers provides window lock repairs for ÂŁ145 per window and handle replacements from ÂŁ90.

Check for Condensation Between Panes

How to Maintain Doors

Clean Door Surfaces and Frames

Testing for air leaks around a front door with a hand.

Dirt, dust, and exposure to weather can affect door performance. Use a damp cloth with mild soap to clean uPVC and aluminium doors.

Tip: Avoid excessive moisture, especially around locks and hinges.

Check Door Seals for Draughts

A well-sealed door enhances insulation. Damaged or worn-out seals can cause heat loss and allow moisture inside. Inspect door gaskets and replace them if necessary.

Tip: Sealing gaps in doors improves both insulation and soundproofing.

Lubricate Hinges and Locks

Doors that squeak or resist closing may need lubrication. Apply a silicone-based lubricant to hinges and locks for smooth operation.

Tip: If the lock feels stiff, servicing may be required to prevent further issues.

Adjust Door Hinges for Proper Alignment

Adjusting door hinges to fix a misaligned uPVC door.

Over time, doors may sag or shift out of place, making them difficult to close. Tighten loose hinges and adjust alignment if needed.

Solution: Window Fixers can inspect and adjust door hinges for better performance.
