What does it cost to repair a broken window

Tuesday 11 June 2024

You will probably have to deal with it at some point, repairing a broken window or replacing a window. For instance because there is a crack in the double glazing or because a hockey ball went through it. Or because you want to replace single glazing with HR++ glass. That makes a considerable difference in energy costs.
Are you curious about the costs of replacing your window, what possibilities there are and the advantages of the different windows after replacement? Then read on.

Window replacement costs

The average cost of replacing a window is about € 150 per square metre. The average minimum cost is € 90 and the average maximum cost is € 200 per square metre. The square metre price obviously depends on the type of glass to be installed. Single glazing is the cheapest option, while HR++ glass is the most expensive per square metre. On the other hand, with HR+++ glass you can save a lot on energy costs.

The price structure of window replacement costs

The price structure for replacing a window is closely related to the surface area and the type of glass. The table below shows the average costs per square metre. To help you make a good decision, we have also listed the various insulation values (U-value) and the energy cost savings. These savings are based on 20 square metres of window compared to single glazing. This so-called U value indicates the insulation value. The lower the number U-value) the better the insulation value. These prices include the professional's labour and include VAT.

Type of glass Average cost per m2 Insulation value Saving on energy costs

Double glazing € 115 2.7
HR €120 1.7 - 2.0 €180
HR+ € 125 1.3 - 1.6 € 220
HR++ € 130 1.2 € 260
HR++ € 170 0.5 - 0.9 € 280
*These are indicative prices based on jobs previously carried out. The final costs may differ from the invoice you receive from us. In the table above you can see that there are different types of insulation glass available. We would like to give you some more information about this.

  • Single glass consists of a single pane of glass.
  • Double glass consists of two single panes.

High performance glass also consists of two single panes, but the space between the two panes is filled with noble gas. The stagnant noble glass in between the two panes of glass offers high resistance to heat and provides extra insulation. The + sign after the letters HR indicates the quality of this insulation. So HR glass has the lowest insulation value, HR +++ glass the highest insulation value. Also pay attention to the KIWA quality mark. This also indicates the quality of the glass.

Do you need or want to replace a window and have a window frame replaced at the same time? This is not a cheap affair. In the table below you will find the average costs for replacing a window including the frame. Please note that these are fixed windows, which cannot be opened. Mentioned prices are including all materials (glass and frame), including VAT and including the hourly wage of the professional, which you can easily book through Zoofy.

Type of window system:

A tilt-and-turn window

Can be opened and tilted outwards. They are used to ventilate the house in summer (open position) but also in winter to ventilate the house without it getting too cold inside.

A sash window

Opens inwards and is ideal when you only want to ventilate a room. Sash windows are mostly used in the bathroom, toilet room or basement.

Sliding window

Slides to the side and saves space. Ideal when you have a window sill with lots of stuff on it. The window can be opened without having to empty the window sill.
