Window & Door Replacement Costs in Ireland (2025 Guide)

Replacing your home’s windows and doors is a significant investment, but one that yields a more comfortable, stylish, secure, and energy-efficient living space for years to come. In Ireland, the cost to replace windows ranges from approximately €300 for basic single-hung models to over €2,500 for large, custom bay or bow windows. For doors, expect to invest anywhere from €400 for standard uPVC models to more than €3,000 for premium composite styles.

But what do these costs actually include? Let’s explore everything you need to know—from average prices and influencing factors to budgeting strategies and expert advice.

Key Takeaways

• Replacement window costs range from €300 for single-hung to €2,500+ for bay and bow types in Ireland.

• Door replacement varies: standard uPVC doors average €400–800; timber runs €800–1,500; composite costs €1,000–2,500+; high-end models can reach €3,500 or more.

• Installation fees depend heavily on project complexity, window/door quantity, and property location.

• Other expenses include disposal of old fittings, finishing work (painting, trims), possible structural repairs, and permits.

• Always plan for contingencies: Budget an additional 10–15% for unforeseen expenses to avoid overspending.

Why Replace Your Windows and Doors?

Upgrading your windows and doors is about more than aesthetics. Modern replacements offer:

• Enhanced home security (modern locks, reinforced frames)

• Superior energy efficiency (windows with low U-values, better airtightness)

• Noise reduction (double or triple glazed glass)

• Low maintenance (weather-resistant materials)

• Higher property value and curb appeal

• Comfort—no more drafts, condensation, or uneven room temperatures

Factors Influencing Window and Door Replacement Costs

Ireland’s window and door replacement costs depend on a variety of factors:

1. Material Choice

• uPVC: Affordable, low-maintenance, and increasingly energy-efficient. The market’s most popular option.

• Timber: Elegant and traditional, but generally pricier due to craftsmanship and upkeep.

• Aluminium: Ultra-durable, modern look, slimmer profiles; higher cost but worth it in contemporary homes.

• Composite: Combines timber’s style and aluminium’s durability; excels in insulation and lifespan but commands the highest prices.

2. Window or Door Size & Style

• Larger or non-standard sizes are more expensive to manufacture and install.

• Bay, bow, and picture windows cost far more than basic single or double-hung units.

• Patio, sliding, or bi-fold doors also add expense due to complex glass panels and fittings.

3. Glazing & Energy Efficiency Upgrades

• Double vs. Triple Glazing: Triple-glazed units are more energy-efficient and durable, but cost more upfront.

• Low-E Glass & Insulated Frames: Enhance performance and comfort; may add €100–200 per window, but save on energy bills long-term.

• A-rated Windows: Stick to products rated for Ireland’s climate & building regulations (U-value ≤ 1.6 W/m²K; top-quality options hit 1.2 W/m²K or lower).

4. Installation Complexity

• Simple swap-outs are cheaper; structural modifications, bay installations, or upstairs windows require more time, scaffolding, or structural support.

• Older houses may need extra prep (e.g., dealing with leaded paint, specialized removals).

5. Location & Local Labour Rates

• Dublin and other urban centres may have higher labour costs than rural areas.

• Accessibility and parking can impact the total bill.

6. Customisation and Finishing Touches

• Bespoke colours, hardware, side panels, window grids, or decorative glass can all increase the price.

• Don’t forget to allow for frame architraves, interior finishing, and painting/new sills.

Average Costs of Different Window Types

Below is a detailed table reflecting the typical price ranges across Ireland for each popular window type, including the cost of materials and standard installation:

Window material and finish will also impact these ranges. For example:

• uPVC: €350–800 (most standard sizes)

• Timber: €700–1,500

• Aluminium: €650–1,700 (due to material and aesthetics)

Bulk projects (e.g., a three-bed semi with 9 windows) can see bundled prices €4,000–9,000 for uPVC and up to €15,000 for timber or aluminium.

Average Costs of Different Door Types

Door replacement prices in Ireland vary by function and material. Here are the most common options:

Custom elements (e.g., sidelights, designer hardware, decorative glass) and fitting can push the cost of a high-end composite entrance well above €3,000. Always ask what’s included in your quote—locks, handles, and letterboxes are sometimes add-ons.

What Do Professional Installation Fees Include?

Professional installation ensures your investment performs as intended for decades. Here’s what you’re paying for:

• Expert labour: Skilled tradespeople measure, fit, and test each unit.

• Weatherproofing and finishing: Full sealing, insulation of junctions, and interior/exterior trimming.

• Site-specific fixes: Rotted frames or surprises in older properties.

• Disposal of old units: Responsible transport and recycling.

Typical labour costs in Ireland:

• Window fitting: €64–137 per window

• Install-only fee: approx. €30 per window linear metre (new build), €50 per window linear metre for renovation, and up to €55 when including detailed finishing.

• Door fitting: €85–400 depending on complexity, architrave, and frame work.

Additional Expenses to Consider

Many homeowners focus on headline prices but forget additional outlays that can tip a budget over the edge:

• Disposal of old windows/doors: Sometimes included, sometimes not (€60+ per unit typical)

• Finishing touches: Paint, trims, hardware upgrades, architrave, plastering, and potential wall touch-ups.

• Access issues or scaffolding: Extra labour for upper floors or awkward sites.

• Repairs: Damp/mould treatment, wood rot, or making good wall finishes.

• Permits or compliance: For major alterations or listed/protected structures, planning or compliance checks may be required.

A smart budget includes a 10–15% cushion for the unexpected.

Benefits of Investing in Energy-Efficient Windows and Doors

Upgrading to modern products is about more than just new frames and glass—it’s an investment in your comfort and your bills:

• Energy Savings: High-performance windows and doors, especially with double/triple-glazing and low U-values, dramatically reduce heat loss. Triple-glazed windows can cut heat loss by 30% vs. double-glazed.

• Lower Heating Bills: Keeping warmth inside means your boiler works less, saving on energy all year.

• Climate Compliance: Ireland mandates a U-value of 1.6 W/m²K or lower for replacements. Aim for 1.2 W/m²K for best results—both for upgrades and new builds.

• Noise Reduction: Say goodbye to road noise and outside commotion with modern multi-pane units.

• Sustainability: Contribute to Ireland’s emission reduction goals (buildings account for 25% of CO₂ emissions).

Step-by-Step Guide: Planning Your Window and Door Replacement Project

1. Audit Your Needs: Inspect current units. Are you replacing all or only those in poor condition?

2. Set a Realistic Budget: Use ranges above as a guide. Add 10–15% for contingencies.

3. Select Products & Materials: Consider durability, style, maintenance needs, and energy efficiency.

4. Request Multiple Quotes: Don’t settle for the first estimate. Compare at least three local suppliers/installers for transparency and the best value.

5. Research Grants or Financial Aid:

   • The Sustainable Energy Authority of Ireland (SEAI) may fund up to 35% of eligible energy upgrades if your home meets certain criteria (see FAQs below).

6. Book Professional Measurement & Survey: Guarantees a flawless result and accurate pricing.

7. Agree on Timeline: Most replacements are completed in 1–3 days, depending on number and type being swapped.

8. Communicate Throughout: Ask questions, request updates, and ensure all extras (disposal, finishing, cleanup) are included.

9. Inspect Final Result: Test every window and door. Keep warranty paperwork somewhere safe.

Frequently Asked Questions

What Is the Best Time of Year for Replacing Windows and Doors?

Mild months—spring or early autumn—are ideal. Installers work more efficiently without extreme cold or heat, and your home isn’t exposed to the elements for long.

Can I Replace Windows and Doors Myself to Save Money?

DIY is possible for small, straightforward jobs by experienced handy homeowners. However, mistakes can void warranties, cause leaks, or lower energy performance. Professional fitting is strongly advised for complex projects and all external doors.

Which Materials Offer the Best Energy Efficiency?

• Triple glazing with argon/krypton gas fills and low-E coatings offer the highest insulation.

• Insulated frames (uPVC, composite, alu-clad) keep heat in and draughts out.

• Composite and advanced uPVC frames rank highest for energy performance in Ireland.

How Long Does the Replacement Process Take?

For a standard home, replacing 6–10 windows and 1–2 doors usually takes 2–3 days. More complex or large bespoke projects may take 1 week.

Are There Grants or Financial Aid Available?

Yes! The SEAI offers grants covering up to 35% of eligible costs for energy upgrades (such as windows and exterior doors) that help improve your home’s Building Energy Rating (BER). Always check their criteria before starting your project.

Smart Tips for Budgeting and Maximising Your Investment

• Request itemised quotes: Ensure all costs (materials, labour, disposal, finishing) are clear.

• Ask about manufacturer warranties and aftercare support.

• Choose energy-efficient options for long-term savings—even if upfront costs are higher.

• Leverage professional advice: Experienced installers can identify the right fit for your property, ensuring maximum comfort and compliance.
