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: €700–1600 (most standard sizes)

• Timber: €1400–3,000

• Aluminium: €1300–7,000 (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

The following estimates reflect typical supply-and-install pricing ranges across Ireland. Exact costs vary depending on configuration, finish, glazing, and structural conditions.

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: €128–270 per window

• Install-only fee: approx. €60 per window linear metre (new build), €50 per window linear metre for renovation, and up to €55 when including detailed finishing.

• Door fitting: €170–800 depending on complexity, architrave, and frame work.

Additional Expenses to Consider

When budgeting for window or door replacement, many homeowners focus on headline pricing but overlook additional expenses that can affect the final bill. Factoring in these common extras helps avoid unexpected costs during installation.

• Disposal of old windows/doors: Sometimes included, sometimes charged separately (typically €60+ per unit).

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

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

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

• Permits or compliance: Major alterations or work on listed/protected buildings may require planning approval or compliance checks.

To stay on track financially, it’s wise to add a 10–15% contingency to your budget for unexpected costs.

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
