Heritage Sash Windows Repairs Sydney 

We restore and repair original timber sash windows across Sydney — fixing rattles, draughts, broken cords and decayed sills while protecting your home’s period character. Our local partners handle on-site work; Barnsbury’s heritage specialists specify the methods and profiles that make the finish look “always original”.

​

• Sash cord replacement, rebalancing & smooth operation

• Rot repairs to sills, jambs, meeting rails and glazing bars

• Draught proofing and acoustic comfort upgrades

• Slimline double glazing where appropriate

• Bespoke replication of missing or beyond-repair components

 

Our Sydney approach:

​

FAQs:

Can you replace just the sash cords?
Yes — cord-only jobs are common. We re-rope, rebalance and check pulley/weight alignment so sashes travel smoothly.
 

Will repairs change the look of my windows?
No. We match profiles and keep sight-lines consistent so the final result looks original — just renewed.
 

Do you work on tenanted properties?
Yes — we coordinate access, protect finishes and minimise disruption.
