VELUX window maintenance: how to keep your roof windows working properly

VELUX roof windows are built to be reliable, practical and long-lasting, but they still benefit from regular care. Like any part of your home, they are exposed to weather, temperature changes, dust, moisture and everyday use.

A small amount of maintenance can help your roof windows open and close properly, reduce avoidable wear and make it easier to spot issues before they become more serious. This guide explains what homeowners can look out for, when maintenance may be enough and when it is worth asking AR Windows for professional advice.

Why VELUX window maintenance matters

A roof window works harder than many people realise. It has to cope with rain, wind, sun, condensation, seasonal temperature changes and repeated opening and closing. Over time, seals, hinges, filters, glazing and internal finishes can all show signs of wear.

Regular maintenance can help:

• keep the window opening and closing smoothly
• reduce the risk of avoidable leaks or draughts
• keep glazing clearer and brighter
• support better ventilation
• identify worn parts earlier
• extend the useful life of the roof window

Maintenance is not a cure for every problem, especially if a window is old, damaged or repeatedly leaking, but it can be a sensible first step for roof windows that are generally in good condition.

Simple checks homeowners can do

There are some basic checks you can carry out safely from inside the home. Only inspect parts of the window that are easy and safe to reach. Do not climb, lean out of windows or attempt work on the roof.

Useful checks include:

• looking for signs of moisture around the frame
• checking whether the window opens and closes evenly
• listening for grinding, catching or unusual stiffness
• checking for visible damage to seals or handles
• looking for condensation between panes of glass
• checking whether blinds or accessories move smoothly
• making sure ventilation flaps are not blocked with dust

If anything looks unsafe, difficult to reach or unclear, it is better to ask for advice rather than forcing the window or attempting a repair.

Cleaning your VELUX roof window

Keeping the glass and frame clean can help the window look better and perform more effectively. Use gentle cleaning methods and avoid abrasive products that could damage the glass, finish or seals.

A soft cloth, mild cleaning solution and careful wiping are usually the safest starting point. Avoid harsh chemicals, abrasive pads and anything that could scratch the glass or frame.

If your window rotates for cleaning, only use the cleaning position if you are confident it can be done safely. If a roof window is high, awkward or difficult to operate, professional help may be the better option.

Watch for early warning signs

VELUX window problems are often easier to deal with when they are caught early. A small operational issue may be linked to wear, dirt, alignment or a component that needs attention. Left alone, it may become more frustrating or more expensive to sort.

Warning signs include:

• the window becoming stiff or difficult to close
• visible gaps, draughts or movement around the frame
• water marks around the reveal or surrounding plaster
• condensation between the panes
• damaged or perished seals
• handles, hinges or locks feeling loose
• blinds no longer running smoothly
• repeated dripping or damp patches after rain

If you notice any of these issues, contact AR Windows with photos and details. The team can advise whether the issue may need maintenance, a repair or replacement.

Maintenance, repair or replacement?

Maintenance is best for windows that are still working reasonably well but need cleaning, checking, adjustment or routine care.

Repair may be needed when there is a specific fault, such as a worn component, leak, stiff operation, broken blind, failed part or misted glazing.

Replacement may be the better option when the window is old, inefficient, badly worn, repeatedly leaking or no longer worth repairing.

The right answer depends on the age, condition, access, window type and the nature of the problem. AR Windows can help homeowners make a practical decision rather than guessing.

What information should you send to AR Windows?

If you need advice, clear photos make a big difference. Before getting in touch, try to send:

• photos of the whole roof window from inside the room
• close-up photos of the problem area
• photos of any visible product code or VELUX plate
• a short description of the issue
• when the issue happens, such as during rain or when opening the window
• the approximate age of the window, if known
• details of access if the window is high or awkward to reach

This helps AR Windows understand the likely cause and advise on the next step.

Could an annual service be worthwhile?

For homeowners with one or more VELUX roof windows, regular servicing can be a sensible way to keep things in better condition. It is especially useful when windows are older, hard to reach, used frequently or part of a wider roof window setup.

An annual service can help identify problems before they become more disruptive and may reduce the likelihood of unexpected faults. You can find out more about planned support on the Annual Service Contract page.

Final thoughts

VELUX window maintenance is a simple but important part of looking after your home. Regular checks, careful cleaning and early advice can help roof windows stay easier to use and may prevent smaller issues from becoming bigger problems.

If your roof window is stiff, leaking, misted, draughty or difficult to operate, AR Windows can advise whether maintenance, repair or replacement is the most sensible next step.
