A VELUX roof window is one of the best investments you can make for your home. It brings in more natural light, boosts ventilation, and transforms lofts, extensions, and attics into bright, comfortable living spaces.
But like all home features, VELUX windows don’t last forever — and knowing when they need attention can save you money, prevent leaks, and improve energy efficiency.
At Lincolnshire Roof Windows, we specialise in repairing, replacing, and installing VELUX windows across Lincolnshire. Here’s your complete guide on how to tell if your VELUX roof window needs replacing.
🌧️ 1. You’re Experiencing Leaks or Draughts
If water or cold air is coming through, it’s a big warning sign your VELUX window may need replacing.
Common symptoms include:
- Damp patches around the frame
- Drips during heavy rain
- Condensation that doesn’t clear
- A noticeable cold draught
Leaks often mean the seals have deteriorated or the flashing kit has reached the end of its lifespan. In many cases, a replacement is the best long-term fix.
🕰️ 2. Your VELUX Window Is Over 20 Years Old
VELUX windows are incredibly durable, but older models lack modern insulation, better glazing, and improved ventilation features.
If your window is more than 20 years old, you may notice:
- Higher energy bills
- Poor sound insulation
- Difficulty opening or staying open
- Faded, brittle, or cracked materials
Upgrading to a new VELUX model can dramatically improve comfort and efficiency.
🌫️ 3. Condensation Between the Panes
If you see mist, fog, or moisture trapped inside the glazing, the unit has blown.
This means the seal has failed and the insulating gas has escaped.
Once this happens, the window loses:
- Thermal efficiency
- Clarity
- Structural integrity over time
A blown unit usually requires a full replacement.
🪟 4. The Window Is Hard to Open or Close
VELUX mechanisms are usually smooth and reliable. Stiff operation can be a sign of:
- A warped frame
- Worn-out hinges
- Internal components failing
If your window sticks, jams, or won’t stay open, it’s time to have it checked.
In some cases repairs are possible — but older models may be more cost-effective to replace.
❌ 5. Visible Damage to the Frame or Flashing
External parts take the brunt of the weather. Over time, you might notice:
- Cracked timber
- Warped or soft wood
- Rust on older flashing kits
- External dents or damage from storms
Damaged frames can let water in and affect the window’s overall structure.
🔇 6. Poor Noise or Heat Insulation
Modern VELUX windows offer excellent thermal and acoustic performance.
If you notice:
- Rooms getting colder
- Noise travelling in from outside
- Higher heating bills
…it may be a sign your current VELUX window is outdated or failing.
🔧 7. Your Home Has Been Recently Renovated
If you’ve:
- Added insulation
- Changed roofing materials
- Extended the loft
- Replastered or reboarded ceilings
Older roof windows might no longer fit correctly or may no longer meet current building standards.
Replacing the VELUX window at the same time ensures everything is sealed, insulated, and performing as efficiently as possible.
🏠 When Should a VELUX Window Be Repaired Instead of Replaced?
At Lincolnshire Roof Windows, we always offer honest advice. Sometimes a repair is all you need.
You may only need a repair if:
- The issue is caused by old flashing
- The pane is cracked but the frame is fine
- A hinge or handle is faulty
- The window is under 15 years old and in otherwise good condition
We’ll assess the window and recommend the most cost-effective option.
