How Much Does Heritage Timber Window Restoration Cost in Sydney?
10 February 2026

It is the first question almost every homeowner asks: what will it cost to restore my heritage timber windows? The honest answer is that it depends, on the condition of the windows, the type and number, access, and the finish you want. But understanding what drives the price helps you compare quotes and make a confident decision.
What affects the price
- Condition: a window needing only re-cording and easing costs far less than one with extensive rot.
- Window type: double-hung sash windows have more moving parts than fixed or casement windows.
- Quantity: restoring a full house of windows is more economical per window than a single repair.
- Access: upper-storey and difficult-to-reach windows add time and equipment.
- Finish: a full strip-back, reglaze, and repaint costs more than targeted repairs.
Restoration versus replacement
Replacement windows can look cheaper up front, but rarely represent better value. Original old-growth timber is denser and more durable than modern softwood, so a properly restored window can outlast a new one. On a heritage-listed property, replacement is also often not permitted, and losing original windows reduces both character and value.
The most reliable way to understand the cost for your home is a proper on-site assessment. We inspect each window, tell you honestly what it needs, and provide a clear written quote with no obligation.
