Timber window frame and sill repairs
We repair damaged timber frames and sills and check sticking or dropping sashes. Tell us which part of the window needs attention.
- Frames and joints
- We repair weathered frame sections and damaged joints, matching the surrounding timber profile.
- Window sills
- We check the sill ends and adjoining frame, replace affected timber and check how water reaches the sill.
- Sticking or dropping sashes
- We check the sash movement, fixings and surrounding timber to plan the repair.
SERVICE SCOPE
Separate sill damage from the whole window
We repair damaged sills, lower rails and local frame sections, distinguishing the timber work from a sticking or dropping sash. The retained frame and the operating hardware guide the repair: sound sections can remain while damaged timber or faulty components are addressed.
Open lower joints and failed coatings can let water reach adjoining timber. We trace the visible water path as part of the repair plan, so replacing a damaged section is coordinated with the work needed to protect it.
- Soft or damaged timber at a sill
- Weathered frame sections
- A frame that needs assessment before replacement
We assess water entry and the retained frame
We check sill ends, lower frame joints and accessible fixings, then measure the existing profile and drainage details. The repair plan identifies damaged sections to remove and sound timber to retain. Replacement sections are fitted to the agreed profile, with joints and protective finishing addressed before we check the repaired window’s operation.
We assess the glass and glazing retention when planning access to the damaged timber. Where glass removal or reglazing is needed, we coordinate that stage with the timber work so the frame can be repaired, the glazing reinstated and the opening finished in the agreed sequence.
Sash-window components and repair choices
We check a sticking or dropping sash’s hinges, catches, balances or cords, fixing timber and frame fit. We distinguish moisture or paint-related contact from worn operating fittings, then plan adjustment and protective finishing around the retained window. A sash that cannot support itself stays out of use until assessed.
We set sash travel, balance and closure alongside the timber repair. Glazing and heritage requirements are incorporated into the work sequence where they affect the opening.
Does a faulty sash always mean replacing the whole timber window?
A sticking or dropping sash does not by itself call for whole-window replacement. We assess the operating mechanism, fixing timber, frame and sill, then distinguish component repairs, timber replacement and any separate glazing work in the proposal.

Our profile, glazing and finishing plan
We specify the retained and replacement sections, profile match, repair access and finish. Preparation, primer and painting boundaries are agreed with you, including any visible difference beside aged paint. Relevant heritage requirements are reviewed before a change to profiles or materials is proposed.
Contact Ellis about the affected window and your suburb. We establish the floor level, external access and whether temporary staging is needed to keep the opening usable. Existing photos or reports can help us prepare; the site assessment confirms the repair quote.

YOUR QUESTIONS ANSWERED
Repair and quote questions
Can a rotten timber window sill be repaired locally?
We inspect the sill, adjoining frame and surrounding timber, trace the moisture source and define the damaged area. Your quote identifies local timber replacement and any wider window repairs needed to reach sound material. Contact Ellis for your on-site assessment and repair quote.
Who repairs timber sash windows?
Contact Ellis for an assessment of your timber sash window. We check the sash, frame, sill, operation and accessible fittings, then confirm the timber repair and hardware work in your quote.
Can you match the profile of my existing timber window frame?
We measure the existing frame profile and review available timber and samples. The proposed replacement profile and finish are confirmed with you before materials are ordered.
Can you repair the timber frame while keeping the existing glass?
We check the glass condition and repair access when planning timber-frame work. Any glass removal, reglazing or replacement is coordinated with a glazier.
Should a window leak be fixed before timber repairs are carried out?
Yes. We trace the visible water path and plan the needed glazing, flashing or leak work alongside the timber repair. We fit replacement timber and complete the agreed finish after addressing the water source, helping protect the repaired sections.
What should be checked before repairing windows on a heritage-listed property?
We inspect the existing window profile, timber and glazing, then plan repairs that suit the property’s heritage requirements. We confirm the sections to retain or replace and the matching finish with you.
