Old sash windows are a beautiful feature of many homes in the east of Ireland, but over time they can become difficult to open, noisy, draughty, and inefficient. Instead of replacing your original windows, our specialist sash window repair service restores them back to full working condition while retaining their period charm.
We repair and restore traditional timber sash windows for Victorian, Georgian, and Edwardian properties throughout Leinster. From rotten wood and broken cords to rattling panes and heat loss, we provide long-lasting repairs designed to improve comfort, appearance, and energy efficiency.


Rotten Timber & Damaged Frames
We carefully remove decayed timber and restore damaged areas using high-quality repair techniques that blend naturally with the original window.
Broken Sash Cords & Sticking Windows
If your sash windows are difficult to open or won’t stay in place, we replace worn cords, rebalance weights, and restore smooth operation.
Draughts, Noise & Heat Loss
Our discreet draught-proofing system helps reduce cold air, rattling, dust, and outside noise while improving insulation.
Loose Glass & Damaged Putty
We repair glazing, replace cracked putty, and secure loose panes to improve both appearance and performance.
Worn Locks & Poor Security
Upgrade your sash windows with modern locks and security fittings without changing their traditional style.
Replacing original sash windows is often unnecessary and expensive. In many cases, professional sash window repair can restore performance, improve insulation, and preserve the traditional character of your home without the cost of full replacement.

We carefully remove your sash windows from their frames to inspect them for hidden damage or structural rot. Flaking paint is safely removed down to the bare timber, so we can fullly assess the state of your sash, the health of the wood and joint strength of the timbers.
Rather than ripping out heritage timber frames and sashes, we cut the rotted areas and replace with matching premium antique old growth pine and bond it securely and restore the window's original structural integrity. This enables your sashes to last for up to another 100 years.
We replace the worn out cords with premium heavy duty waxed cotton lines and service the pulleys. The windows are then counterbalanced with lead or iron weights to ensure smooth, effortless opening and closing every time for years and decades to come.
We install hidden high performance draught proofing brushes into the timber beads, creating an airtight seal, eliminating rattle, draughts and heat loss. We then seal any remaining lead paint in the timber with a premium primer, finishing with a long lasting paint to bring out your sashes beauty.
Looking for comprehensive care? Beyond structural repairs to your sashes, we provide specialised sash window draught proofing, precision sash cord replacement and professional timber window painting services along the east of Ireland mainly in Dublin, Wicklow, Wexford and Waterford.
Stop living with rattling frames, cold draughts and windows that don't do what they're supposed to do... Our sash window restoration specialists can restore the beauty, comfort and performance of your original sash windows without the massive outlay of unnecessary replacement.

Wooden window replacement is absolutely worth considering when your frames have suffered significant structural damage, warping, or rot beyond repair. However, in many heritage period properties, timber window restoration is often the smarter investment, preserving the original character of your home while bringing performance up to modern standards. A full wooden window restoration can extend the life of your frames by 20–30 years, or more, at a fraction of the replacement cost. We always recommend a professional assessment first, as what looks like a replacement job is often a timber window refurbishment.
Yes, in most cases, rotted wood windows can be repaired rather than replaced. Our timber window repairs service replaces the affected areas with like for like timber to rebuild damaged sections, including rotted window trim and frame joints. Window refurbishment of this kind is structurally sound and, once painted, virtually invisible. The key factor is how deep the rot has penetrated. Surface and mid-level rot is almost always repairable, while full-frame decay may require a section replacement. Either way, a timber window maintenance plan after repair is essential to prevent recurrence.
In many cases, restoring traditional sash windows is considerably more cost-effective than complete replacement. Restoration can preserve the original character of the property while improving insulation, operation, and appearance. Our Sash Window Restoration service focuses on maintaining original features while improving functionality and energy efficiency.

Walsh Heritage navigated the complex historical registry regulations with absolute mastery. Their care for our family's legacy was profound. We are endlessly relieved to have found them.

I was terrified of the restoration process ruining the integrity of our 19th-century stonework. Their team restored it flawlessly while handling all the bureaucratic red tape. Truly prestigious work.

Their artisans possess a rare reverence for the past. From the meticulous woodwork to securing the necessary municipal approvals, Walsh Heritage was the guardian our estate needed.
