Why oiling your windows matters
Every time you open or close a window, the hinges, handles, and locking components experience a little friction. Without lubrication, these metal parts can dry out or corrode slightly, leading to:
- Stiff or squeaky hinges
- Handles that are hard to turn
- Windows that don’t shut tightly, letting in draughts
- Extra strain on locking mechanisms, shortening their lifespan
Regular lubrication keeps these parts moving freely and helps maintain a tight seal when your window is closed, improving energy efficiency and home insulation at the same time.
What you’ll need
Before you set time aside to oil your window, check to make sure you’ve got the following household items:
- A soft cloth or microfibre towel
- A vacuum or soft brush to remove dust and dirt
- A mild detergent and warm water for cleaning
- A silicon-based spray lubricant or PTFE (Teflon) spray - ideal for uPVC and aluminium windows
Avoid using heavy oils like engine oil or WD-40, as these can attract more dust and make parts stick over time.
Step-by-Step: How to oil your window’s moving parts
Read simple instructions for how to oil your window’s hinges and moving parts at home:
1. Open and inspect the window
Fully open the window so you can reach all moving parts: hinges, friction stays, locking points, and the handle base. Take a moment to look for signs of dirt, corrosion, or damage.
If your handle feels particularly stiff, check for visible screws or obstructions first. This sometimes helps to loosen a stiff window handle even before you apply oil.
2. Clean the hinges and mechanisms
Before applying any lubricant, remove dust and grime so the oil can work properly. To do this, you can:
- Use a vacuum or brush to clear out dirt from hinge channels.
- Wipe the area with a soft cloth dipped in mild detergent.
- Dry everything thoroughly.
A clean surface ensures the lubricant spreads evenly and doesn’t trap grit.
3. Apply lubricant to moving parts
Spray or apply a small amount of silicon or PTFE spray (it won’t stain or attract dirt) onto:
- Hinges and friction stays (the metal arms that hold your window open)
- Locking mechanisms and rods around the frame
- Handles and pivots that feel stiff
Turn or operate the handle a few times to help distribute the lubricant through the mechanism.
4. Wipe away excess
Use your clean cloth to gently remove any surplus oil. Leaving too much lubricant behind can attract dirt and create a sticky residue.
5. Test the movement
Open and close the window several times. It should feel noticeably smoother and quieter. If it’s still stiff, repeat the process with a touch more lubricant until it moves freely.
What if this doesn’t fix my window?
If your window still feels stiff or noisy after a couple rounds of oiling, there may be a deeper issue such as:
- A worn hinge or friction stay that needs replacement
- Rust or corrosion on older frames
- A misaligned sash preventing smooth movement
In these cases, professional repair or window replacement may be the best long-term solution. Modern double-glazed uPVC windows are designed with advanced hinges and locking systems that require minimal maintenance and resist corrosion - ideal for keeping your home secure, quiet, and energy-efficient.

How often should you oil your windows?
Oiling your windows once or twice a year is usually enough to prevent stiffness and squeaks.
The best times to do it are:
- In spring: after winter weather may have dried or stiffened the mechanisms.
- In autumn: before colder months when condensation and moisture can increase friction.
If you live near the coast or in a dusty or industrial area, consider oiling every few months for extra protection.
Extra maintenance tips
Oiling is just one part of simple window care. To keep your windows performing at their best:
- Clean the frames regularly using mild soap and water (avoid harsh chemicals as this can damage seals).
- Inspect rubber seals for wear or cracking and replace if needed to maintain insulation.
- Check for draughts around the edges and ensure windows shut firmly.
- Tighten any loose screws on handles or hinges if they start to wobble.
A few minutes of upkeep each season can prevent costly repairs and improve energy efficiency in your home.
