Essential Factors that Affect the Cost of Window Glass Replacement Jobs
The cost to replace your window glass will depend on many factors. Consider the following aspects to carefully budget your expenses.
Type of glass
Your choice of window glass materials considerably impacts the cost of replacement. Tempered glass, tinted glass and laminated glass are among the common types of glass windows.
Laminated glass, for instance, is a type of glass with two outer-layer sheets designed to protect the interlayer from early damage.
The indicative costs of glass windows are:
- $35 per m2 for float glass
- $145 per m2 for low iron glass
- $200 per m2 for double-glazed glass
- $220 per m2 for low emission glass
- $350 per m2 for laminated glass
Low emission and tinted glass sheets are more costly than plain glass as they have special treatments that help reduce heat transmission. Also, energy-efficient glass materials can be expensive.
Removing a damaged single pane of glass costs less than replacing the entire glass window. Tackling a triple-pane or double-hung window will mean more materials and longer time to complete the window replacement project.
The size of the glass also factors in the cost of window replacement. Window glass cutting may be required to fit the glass into the frame, which may complicate the process and attract additional costs.
If you notice signs of cracks or holes in the window glass near the side of your window frames, seek advice from your glazier on costs for repair or replacement.
Often when window frames are irreparable, glass panes need to be replaced as well. This can significantly influence the project cost.
Calling an emergency glazier to replace a broken glass outside the normal working hours will incur higher fees. Window frames that need immediate repairs or replacement will also add to the cost.
Note: Disposing of broken glass windows and frames often have associated fees. The best thing to do is to clarify these terms with your local tradie.
The Cost of Glazing by Type
As mentioned, the type of glass material costs vary.
Here are indicative costs of clear float glass.
- $93 to $98 per m2 for 3.00mm
- $102 to $108 per m2 for 4.00mm
- $116 to $119 per m2 for 5.00mm
- $120 to $126 per m2 for 6.00mm
- $159 to $165 per m2 for 8.00mm
- $176 to $188 per m2 for 10.00mm
- $206 to $218 per m2 for 12.00mm
For laminated glass, expect to pay around:
- $215 to $217 per m2 for 6.38mm
- $307 to $315 per m2 for 10.38mm
- $318 to $328 per m2 for 12.38mm
Toughened glass sheets have the estimated cost of:
- $221 to $238 per m2 for 4.00mm
- $240 to $254 per m2 for 5.00mm
- $263 to $275 per m2 for 6.00mm
- $510 to $539 per m2 for 10.00mm
- $607 to $642 per m2 for 12.00mm
The cost of glazing varies depending on the size of the glass and type of window frames used such as wood, aluminium or vinyl.
While the above rates may be used as a reference, consider asking a qualified window glass replacement contractor to verify the project cost.
Note: The actual removal of existing glass windows may have a different set of pricing. Always request for itemised quotations to know the separate cost of materials and labour.
