Window replacement cost in Ireland
Legacy guide: external source review is pending. How we review guides
New windows can improve warmth, comfort, noise and kerb appeal, but quotes can be difficult to compare. One installer may quote supply only. Another may include removal, fitting, disposal, making good and warranty.
Irish window guides show wide ranges. Some examples place individual double-glazed windows in the hundreds of euro, while full-home replacement can range from several thousand euro to €15,000+ depending on the number, size and specification.

Double glazing vs triple glazing
Double glazing is usually cheaper and suits many homes. Triple glazing costs more but can improve comfort and noise reduction, especially in exposed homes, colder rooms or energy upgrade projects.
What affects the price
- Number and size of windows.
- uPVC, aluminium or timber frames.
- Double or triple glazing.
- Bay, sash, tilt-and-turn or custom shapes.
- Removal, disposal, fitting and making good.
- Scaffolding, access and ventilation details.
Do not ignore ventilation
New windows can make a home more airtight. That is good for comfort, but homes with existing condensation or mould need ventilation considered before replacement. Ask about trickle vents and kitchen or bathroom extraction.
