Sash Window Refurbishment in Dublin 4

Traditional Timber Window Restoration with Modern Performance

For this project in South Dublin, we refurbished the client’s existing timber sash windows, restoring their original character while significantly improving energy efficiency, security, and ease of operation. Our specialist sash window refurbishment service in Dublin is ideal for period properties, heritage homes, and conservation areas.

Our Approach

Each sash window was carefully assessed to retain as much of the original hardwood as possible while upgrading performance where required.

• Existing sash windows were carefully removed and the openings temporarily secured
• Window sills were repaired or replaced to ensure long-term durability
• Outer liners and pulley stiles were repaired or replaced as required
• New non-stretch cotton sash cords were installed for smooth, balanced operation
• New hardwood parting beads and glazing beads were fitted
• All sashes were sanded back to remove existing paint and prepare the timber
• Finished with three coats of high-quality paint
• Refurbished sashes were refitted into the existing repaired frames

Energy-Efficient Double Glazing Upgrade

To improve insulation while maintaining the traditional appearance of the windows, we installed:

• 4-8-4 clear double glazing units
• Warm edge spacer technology
• Minimal seal sightlines
• Black spacer bars for an authentic heritage finish
• Argon gas filling for enhanced thermal performance

This upgrade improves comfort, reduces draughts, and helps lower energy costs while preserving the original sash window proportions.

Traditional Polished Brass Ironmongery

Period-appropriate polished brass ironmongery was selected to complement the
character of the Dublin 4 property:

• Steel sash weights, 50mm square
• Large square pulleys – polished brass finish
• Brighton fastener – polished brass
• Two sash lifts – polished brass
• One sash ring – polished brass

The Result

The completed sash window restoration in Dublin 4 delivers a perfect balance of traditional craftsmanship and modern performance. The windows now operate smoothly, provide improved thermal efficiency, and retain the architectural integrity of the home.
