How Much Do Window Sills Cost in Ireland? (2026 Price Guide)

Whether you are budgeting for a new build or upgrading your home's insulation, understanding the cost of window sills is essential. Prices vary significantly based on material choice, reveal depth, and customization.

In Ireland in 2026, standard exterior window sills cost between €15 and €45 per linear meter for PVC, €30 to €75 per meter for precast concrete, and €45 to €110 per meter for custom 2mm marine-grade powder-coated aluminium (supply only).

2026 Material Price Comparison Table

Here is a breakdown of average supply-only costs per linear meter across Ireland:

| Material | Price per Linear Meter (Standard Depth) | Price per Linear Meter (Deep Reveal EWI) |

|---|---|---|

| Standard uPVC | €15 - €30 | €35 - €50 |

| Precast Concrete | €30 - €60 | N/A (Not suitable for EWI) |

| Silver Granite | €65 - €100 | €120 - €180 |

| 2mm Marine Aluminium | €45 - €70 | €75 - €110 |

| Hardwood (Timber - Internal) | €35 - €65 | N/A |

Key Factors That Influence the Cost

• Reveal Depth: Standard sills are 150mm deep. If you are retrofitting External Wall Insulation (EWI), you will need extended sills (up to 350mm or 400mm deep) to cover the thick EPS boards. Deep reveals require larger metal blanks, increasing the material cost.
• Color Customization: Standard finishes (like mill-finish aluminium or white PVC) are cheapest. Architectural Polyester Powder Coating (PPC) to match window frames (such as Anthracite Grey RAL 7016 or Jet Black RAL 9005) adds a premium but ensures a lifetime maintenance-free finish.
• Welded Stop-Ends: Adding factory-welded stop-ends to prevent water ingress into reveals costs roughly €10 to €20 per side, but prevents thousands of Euros in future render repairs.
• Delivery & Location: Bulky materials like precast concrete incur high freight charges. Lightweight aluminium sills are significantly cheaper to ship nationwide from our Dublin workshop to Cork, Galway, Limerick, or Belfast.
