How much does it cost to replace a window pane?
Replacing a window pane costs on average between €130 and €220 per square metre, depending on the type of glass you choose. The costs consist of the glass itself plus the labour for removing the old pane and installing the new one. Double glazing is the most affordable, while HR+++ glass offers the best insulation but is also the most expensive.
Costs per type of glass
| Type of glass | Price per m² |
|---|---|
| Double glazing | €150 |
| HR glass | €150 |
| HR+ glass | €150 |
| HR++ glass | €130 |
| HR+++ glass | €220 |
The table shows the costs for replacing a window pane for the most common types of glass. HR++ glass is surprisingly affordable while still offering good insulation. HR+++ glass is the most expensive option but results in the lowest energy bill due to its superior insulation value.
The U-value determines how much heat escapes through the glass: the lower the number, the better the insulation. Double glazing has a U-value of 2.7, HR glass between 1.7 and 2.0, HR+ between 1.3 and 1.6, HR++ around 1.2 and HR+++ between 0.5 and 0.9. The U-value is an important indicator for your energy savings.

Costs of window pane replacement per frame type and window system
The costs for replacing a window pane depend not only on the type of glass, but also on the frame material and the window system. A PVC frame is the most affordable, while aluminium is the most expensive option. Below you can see what different configurations cost.
Costs of frame and glass per area
| Area | PVC frame | Wooden frame | Aluminium frame |
|---|---|---|---|
| 1 m² | €250-500 | €400-650 | €800-1,050 |
| 20 m² | €7,800 | €10,400 | €18,200 |
| 40 m² | €15,600 | €20,800 | €28,000 |
Costs per window system (1 m²)
Different prices apply to various window systems excluding labour costs. A tilt-and-turn window can open outwards and tilt, ideal for ventilation. A hopper window opens inwards and is often used in bathrooms. A sliding window slides to the side and is space-saving.
| Window system | PVC | Wood | Aluminium |
|---|---|---|---|
| Fixed | €100-200 | €150-250 | €250-350 |
| Tilt-and-turn | €200-350 | €350-450 | €400-500 |
| Hopper | €200-300 | €350-500 | €450-550 |
| Sliding window | €700-800 | €800-900 | €1,000-1,300 |
Price-determining factors for replacing a window pane
The costs for replacing a window pane vary per situation. In addition to the type of glass and the dimensions, many other factors play a role that influence the total price. Below you can read which aspects increase or decrease the costs and how you can influence the final price yourself.
Glass type and insulation value
HR+++ glass costs more than double glazing because the production is more complex and multiple coatings are applied. These extra layers ensure a lower U-value, meaning you have less heat loss and save on your energy bill in the long run. You earn back the higher purchase price through lower heating costs.
Dimensions and window area
The larger the window area, the higher the total costs. For larger projects, the price per square metre is often more economical than for a single small window. Always measure the width and height of the glass itself, not the frame, to get a realistic price estimate.
Frame condition and repair needs
If the frame is rotten or damaged, it must first be repaired or replaced before the new glass can be installed. These extra activities cost time and material, which increases the total costs. A well-maintained frame saves you these extra expenses.
Complexity and accessibility
Difficult to reach windows on higher floors or non-standard sizes require more time and expertise. The professional may need to take extra safety measures or use special tools, which extends the labour time and increases the costs.
Emergency jobs
Emergency jobs are more expensive than planned work because the professional must adjust their schedule and possibly reschedule other appointments. Do not delay tasks where possible: tackling small cracks or damaged sealant edges early prevents the damage from becoming larger and the repair more expensive.
Weekend work and timing
Work at the weekend costs more than during the week due to surcharges. Plan your task on a weekday to keep the costs as low as possible.
Window orientation and solar protection
South-facing windows receive more sunlight and can benefit from solar control glass, which lowers the indoor temperature. North-facing windows benefit from maximum insulation to limit heat loss. The choice of specific coatings affects the price.
Preparation by the customer
Good preparation saves time and therefore money. Ensure that the windowsill is empty, curtains are removed and there is sufficient space around the window. This allows the professional to get straight to work and you do not have to pay for preparation time.
Choice of platform
At Zoofy, you know what you pay in advance, without surprises and without call-out charges. You receive a clear quote based on the information you provide, so you can estimate the costs beforehand.
Hiring a local professional
Local professionals can be on-site faster, which saves on travel time and any urgency surcharges. This makes the job more efficient and often also cheaper.
Type of window system
A fixed window is easier to replace than a tilt-and-turn or sliding window. With movable systems, the professional must also check and adjust the mechanics, which takes extra time and increases the price.
Number of window panes to be replaced
Having multiple panes replaced at once is often more economical per piece than separate tasks. The professional is already on-site, saving you on fixed costs such as travel time.
Availability of materials
Standard glass sizes are directly available, but custom work can have a longer delivery time. With tight stocks or special orders, costs can rise due to extra shipping costs or urgent deliveries.
Additional costs and surcharges
Extra costs are dependent on the specific situation. At Zoofy, you do not pay call-out charges.
- For emergency jobs, a surcharge applies because the professional must adjust their schedule
- Work at the weekend is more expensive than during the week
- A screen costs €50-€100 excluding installation
- A ventilation grille costs €80-€130 excluding installation

How does the professional work when replacing a window pane?
Replacing a window pane follows a fixed sequence of steps, from measuring to finishing.
- Measuring and assessment: The professional measures the window accurately and checks if the frame is in good condition. Any damage to the frame is noted for repair before the new glass can be installed.
- Preparation by the customer: You ensure that the windowsill is empty, curtains are removed and there is sufficient space around the window. This preparation saves time and prevents costs from rising unnecessarily.
- Removing old glass: The damaged or old glass is carefully removed, including old sealant and rubbers. The professional works carefully to prevent damage to the frame.
- Preparing the rebate: The rebate in which the glass is placed is cleaned and repaired if necessary. A clean surface ensures optimal adhesion of the new sealant.
- Installing new glass: The new glass with KIWA quality mark is positioned with glass blocks and sealed. The professional checks if the glass is level and fits well.
- Finishing: The sealant must dry for 24 hours before the window can be fully loaded. The total duration for replacing one window pane is 1-2 hours, depending on the size and complexity.
How can you save on replacing a window pane?
There are several ways to reduce the costs of replacing a window pane without compromising on quality.
- Prevent problems: Regularly check your windows for cracks, damaged sealant edges and condensation between glass layers. Tackling small problems early prevents damage from increasing and repair costs from rising.
- Prepare: Empty the windowsill, remove curtains and ensure free access to the window. This preparation saves the professional time and keeps labour costs low.
- Plan smartly: Book the task during the week and avoid emergency assignments. Weekend and urgency surcharges can significantly increase costs.
- Choose HR++ glass: This glass has the shortest payback period of approximately 10 years due to the favourable balance between purchase price and insulation value. It is therefore the most chosen type of glass.
- Book via Zoofy: You get a fixed rate in advance, without call-out charges and without surprises. You only pay after completion of the task.
Common causes of glass damage
Glass damage can have various causes, each with its own consequences for comfort and safety.
Condensation between double glazing
Condensation between the glass layers occurs because the seal is damaged. This problem cannot be repaired and requires full glass replacement. It leads to reduced insulation and higher costs if you delay it.
Thermal stress
Large temperature differences, especially with direct sunlight on cold glass, cause stress that can lead to cracks. This occurs more often with south-facing windows.
Outdated sealant edges
Old sealant can come loose and show cracks, allowing draughts and moisture in. This increases your heating costs and can lead to mould formation around the frame.

Frequently asked questions about replacing a window pane
How long does it take to replace a window pane?
On average 1-2 hours per pane, depending on size and complexity. The professional needs time for removing the old glass, preparing the rebate and installing and sealing the new glass.
Can I replace a window pane myself?
Installing glass is professional work that requires precision. Incorrect installation can lead to leaks, draughts or glass breakage, which actually results in higher costs due to extra repair work.
Is the old window pane disposed of?
Ask the professional in advance if disposal of the old glass is included in the quote. Some professionals charge a small surcharge for this, while others include it as standard in the price.
Is there a warranty on the glass and the installation?
Manufacturer's warranty on glass is usually 10-20 years. Ask the professional about the installation warranty on the mounting itself, so you are covered in case of any problems.
Can glass replacement be done in the winter?
Yes, but dry weather is ideal for sealing. The professional can advise on the best timing and take extra measures if necessary to guarantee good adhesion.
Can every frame support HR+++ glass?
Not always. Old frames sometimes have rebates that are too shallow for thicker insulation glass. The professional checks during the assessment if your frame is suitable for the chosen type of glass.
What if there is condensation between the double glazing?
This indicates a damaged seal between the glass layers. The glass must be replaced because this problem cannot be repaired and the insulation value is greatly reduced.
Does my insurance cover glass damage?
Many contents insurance policies have glass coverage. Always report damage to your insurer first before having the task performed, so you know for sure if the costs will be reimbursed.
Do I need to stay home during the installation?
Yes, someone must be present to let the professional in, provide access to the window and check the work before you complete the order.
Can I get a subsidy for insulation glass?
There are sometimes municipal or national subsidy schemes for energy-saving measures such as HR++ or HR+++ glass. Check your municipality's website for current schemes.
