Frequently asked questions about window hardware maintenance

Well-maintained window hardware ensures smooth operation, reliable sealing and a longer service life for PVC windows. This guide explains what to check, how to lubricate and clean mechanisms, simple adjustments you can make yourself and when to call a professional.

Why regular maintenance matters

• Hardware bears the load of opening, closing and sealing the sash.
• Dirt and dust accelerate wear of hinges and sliding parts.
• Lack of proper lubrication can cause corrosion, sticking and premature failure.

Preventive maintenance reduces repair costs and avoids emergency breakdowns.

Basic toolkit for care

• Soft cloth and a soft-bristled brush.
• Plastic scraper or wooden stick to remove stubborn grime.
• Screwdrivers (Phillips and flat) for adjustment screws.
• Silicone spray or lithium grease; graphite for locks.
• Safety gloves and glasses.

What lubricants to use

• Silicone sprays or lithium-based greases are recommended for moving parts.
• Avoid vegetable or generic machine oils — they attract dust.
• Graphite powder works well for locks and key mechanisms.

Recommended maintenance frequency

• Basic inspection and light lubrication: once a year (spring or autumn).
• In dusty or coastal environments: twice a year.
• Immediately if you notice squeaks, sticking, or reduced sealing.

Step-by-step lubrication of hinges and mechanisms

1. Set the window to a convenient opening mode (turn/tilt).
2. Clean visible parts with a soft brush to remove dust.
3. Apply a small amount of silicone spray to hinges and sliding elements.
4. Operate the window several times to distribute the lubricant evenly.
5. Wipe away excess with a clean cloth.

Cleaning gaskets

• Wipe gaskets with warm soapy water.
• Avoid aggressive solvents — they damage rubber.
• After cleaning, apply a thin layer of silicone to restore elasticity.

Common issues and quick fixes

• Squeak when opening: clean and lubricate the hinges.
• Poor sealing: adjust the compression screws on the strike plates.
• Stiff handle: check fasteners, tighten screws and lubricate.
• Drafts: inspect gasket condition and adjust sash alignment.

When to call a professional

• Broken or heavily worn hinges and locks.
• Complex multi-point adjustment needed.
• Frame damage or significant sash deformation.

Practical tips to reduce wear

• Don’t force the sash if it resists — find and fix the cause first.
• Avoid slamming the sash or putting pressure on the handle.
• In freezing conditions, thaw frozen gaskets gently rather than forcing opening.

Conclusion

Simple, regular care of window hardware keeps windows working quietly and saves money. A short annual check and proper lubrication prevent most common problems.

FAQ — quick answers

Q: Which lubricant should I use for PVC windows?

A: Use silicone or lithium-based lubricants. Silicone is especially good for rubber gaskets and won’t attract dust.

Q: Can I clean hardware with strong detergents?

A: No. Use warm water with mild soap. Solvents and bleach can damage metal and rubber parts.

Q: How to tell if the sash needs adjustment?

A: If it doesn’t close evenly, rubs the frame, or there’s noticeable draft along the edge, it likely needs adjustment.

Q: How long does a basic inspection take?

A: About 10–20 minutes per window for inspection and light lubrication.

Q: Is it OK to use WD-40 on window hardware?

A: WD-40 can be used in emergencies but is not a long-term solution; it can remove protective greases and attract dirt. Prefer silicone sprays.

Q: What if the handle spins freely and the window doesn’t lock?

A: Check the screws and the spindle. If tightening doesn’t help, the locking mechanism may be damaged and requires replacement.
