Window Replacement Cost Ireland: What to Expect in 2025

Upgrading your home’s windows can dramatically boost comfort, energy efficiency, and curb appeal. However, understanding the true cost of window replacement in Ireland in 2025 is crucial for homeowners seeking the best value and highest return on investment. Whether you’re looking to modernise, increase resale value, or reduce your energy bills, this comprehensive guide details real-world pricing, value, and grant opportunities for window and door replacement in Ireland.

Typical Window Replacement Costs in Ireland

The cost to replace windows in a house in Ireland typically falls between €3,000 and €10,000 for most properties, but can be higher for large homes or those selecting premium options. Your final price depends on factors such as:

• Total number of windows to be replaced

• Window style, size, and opening functions

• Frame material (uPVC, aluminium, timber, composite)

• Glazing type (double, triple, or enhanced energy-efficient glass)

• Access difficulty and installation complexity

Per-Window Price Overview

These prices generally include both the window unit and standard installation, though situations involving difficult access, custom shapes, or significant remedial works may incur extra labour fees.

Key Takeaways

• Budget for Small Homes: €3,000–€6,000 depending on window count, materials, and styles.

• Medium-Sized Homes: €6,000–€10,000 for window replacement with quality materials and professional installation.

• Larger Properties and Premium Upgrades: Costs can exceed €10,000, particularly where high-spec glazing and bespoke designs are chosen.

• Additional Costs: Installation fees, disposal of old windows, and finishing touches can add €500–€2,000+ per project.

• Best Value: Obtain multiple quotes from experienced, insured contractors and compare specifications—and always check for available grants.

Factors That Influence the Cost of Window Replacement

 

1. Size, Quantity, and Style

• Larger or feature windows (such as bay or bow) are more costly due to custom manufacturing and installation requirements.

• Standard-sized casement or sash windows are generally more affordable.

2. Frame Material

uPVC is by far the most popular and cost-effective option for Irish homes thanks to its durability, efficiency, and low price, while timber and aluminium are chosen for style or historic matches.

3. Glazing Options and Energy Ratings

• Double-glazed windows are standard. Triple-glazing is becoming more common, offering increased comfort and energy savings in colder climates, but with an extra upfront cost (typically €100–€200 more per window).

• A-rated windows: Investing in the highest available energy rating (A or A+) can significantly reduce heat loss and annual heating bills by €100–€400, depending on your previous windows.

4. Labour and Installation

• Professional installation ensures windows perform to specification and avoid air leaks, condensation problems, and security risks.

• Labour fees in Ireland: Typically €64–€137 per window, or €120–€350+ per day for complex projects.

• Difficult access (upper-storey, narrow streets) or remedial works (repairing rotten sills, unusual wall construction) may increase installation costs.

5. Finishing, Disposal, and Unexpected Extras

• Disposal of old windows: Not always included—ask your installer for a clear breakdown. Standard disposal fees may add €200–€500 to the job.

• Finishing work: Painting, replastering, and trim can also add to your budget.

Typical Cost Examples by Home Size

Example: Replacing 9 uPVC double-glazed windows in a typical 3-bed semi-detached house is likely to cost €4,050–€9,000, while the same in timber or aluminium may exceed €7,000–€15,300.

Window Types and Custom Features

Common Window Styles

• Casement: Hinged on the side, swings open—most popular and energy-efficient (from €91–€913 each).

• Tilt-and-Turn: Flexible ventilation, modern looks (from €200–€1,000).

• Double-Hung/Sash: Vertical sliding, traditional character (from €137–€593).

• Bay and Bow: Feature windows, panoramic light (from €1,100–€3,500).

• Skylight/Roof: Brings light into attics and extensions (€800–€2,500).

Energy-Efficient Upgrades

Choosing triple glazing, low-E coatings, or argon gas fills will cost more initially but can pay for themselves quickly through reduced heating bills and a warmer, more comfortable home.

Additional Costs to Consider

• Professional Installation: Always budget for skilled labour—cutting corners here can lead to air leaks, condensation, or security risks.

• Old Window Removal/Disposal: Many installers charge extra to remove and recycle your old units.

• Finishing Touches: Painting or plaster repairs after installation may be necessary, especially in older homes.

• Customisation: If you choose special shapes, historic styles, coloured frames, or bespoke designs, expect a higher quote.

Energy Efficiency Grants and Support in Ireland

Major Grants Available (2025)

SEAI One Stop Shop Grant:

• Up to €4,000 for windows (detached house), €3,000 (semi-detached), €1,800 (mid-terrace), €1,500 (apartment).

• Up to €800 per external door, two max.

Estimating Energy Savings: Why Upgrade?

• Replacing old single-glazed or poor double-glazed windows with modern A-rated models can save you €100–€400 per year in energy costs, depending on the size of your home and previous window performance.

• Better windows reduce noise, condensation, and draughts, and can improve health and comfort for your family.

• Upgrading is essential to meet new building energy standards and raise your BER, which is crucial for future property sales.

Common Questions and Detailed Answers

Can Windows Be Replaced During Winter?

Yes—it is possible year-round. Professional teams minimise heat loss by replacing one window at a time and sealing work as they go. However, severe weather may extend installation times slightly.

What About Warranties?

Expect 10–25 years for uPVC and 10–30 years for aluminium frames, covering manufacturing and installation. Always read the fine print for inclusions and exclusions.

Are There Other Financial Supports?

Besides national grants, check if any utility providers, county councils, or community sustainability projects offer additional incentives.

How Do I Choose the Right Contractor?

• Choose operators with insurance, clear oversight of SEAI grant processes, and robust aftercare services.

• Seek local reviews and consider businesses that offer in-person home assessments and detailed, itemised quotes.

Tips for Budgeting Your Window Replacement Project

• Research thoroughly: Understand all material, efficiency, and design options.

• Collect competing quotes: Aim for at least three, with all details in writing.

• Check for grants: Maximise supports and coordinate larger upgrades (like insulation) if considering window grants.

• Set aside a contingency fund: Unexpected remedial work is common, especially in older buildings.

• Value efficiency: Prioritise windows with high U-value and BER improvements, as utility savings add up over the years.

• Plan for repairs and decoration: Account for any painting, plaster upgrades, or exterior finishing that new windows may require.
