Element Records Before Heritage Timber Repairs
Use a room, elevation or simple element name such as front window or side door so everyone discusses the same item. Note sticking, visible decay, water entry, damaged profiles or missing hardware from safe normal access. Existing photos are optional for the first enquiry; do not disturb coatings, glazing or timber to make a record. The site assessment provides the accessible condition detail needed to develop the scope.
Old hardware, profiles, glazing bars, joints and paint layers can help explain how an element was built and what makes it visually significant. Recording those details before removal creates a better basis for repair or replication. It also allows owners, designers and heritage advisers to discuss a proposed change using evidence rather than a guess based on a modern equivalent.
Note when water entry occurs, which areas remain damp and any previous repairs. Accessible observations help the assessment, but hidden drainage, flashing, glazing or wall problems may need another specialist. Ask who investigates the cause and what must be resolved before the timber repair is finished; replacement timber alone does not establish that water entry has been fixed.

Retained Fabric, Concealed Decay and Quote Allowances
Ask the proposed scope to identify retained material, local repairs, replicated components or replacement items and the evidence behind each decision. Include profile references, finish responsibilities and unresolved conditions. The method must suit the assessed element and agreed conservation approach; a photo or generic repair description is not a specification for cutting or rebuilding old timber.
External joinery can conceal deterioration behind paint, trims or internal linings. MEL ONE checks the accessible timber on site and agrees any careful opening-up needed to identify the damage. If hidden decay is found, we explain the additional repair and agree the scope and quote with you before proceeding.
Approvals, Glazing, Paint and Staged Work
Include any known listing status, conservation advice, approved drawings and relevant correspondence with your project record. We plan the timber repair from the agreed conservation approach and project documents. Use PlanSA guidance to start an approval check and refer unresolved requirements to the relevant authority, which determines any required approval.
A repaired timber window or door depends on more than its joinery. Glazing, putty or sealant, hardware adjustment, paint preparation and final coating need to follow an appropriate sequence. Clarifying those interfaces early prevents a repaired sash or door from being installed without the finishing work required to protect it from weather and daily use.
For several affected openings, agree which need attention first and which can wait. Keep the element records and agreed repair approach together so later stages use the same profile references, approval information and finishing details.
Maintenance Records After Timber Repair
Timber lasts longer when paint failure, failed sealant, blocked drainage paths and exposed end grain are addressed early. At handover, ask what has been repaired, which finish system has been used, when it should be reviewed and which warning signs—such as cracking, sticking, water entry or soft timber—should prompt another inspection.
Preparing a heritage timber repair scope
What should a heritage timber condition record contain?
Identify each door, window or external element, the visible symptoms, access limits and any existing conservation or approval advice. Photos and approximate dimensions are optional at first enquiry; the assessment develops the repair scope.
How should hidden decay be handled in the quote?
Record what can be assessed, what remains concealed and any agreed investigation stage. Additional damage should be documented with its scope and price effect agreed before the affected repair proceeds.
Who checks approval requirements for a proposed repair?
Confirm the property status and proposed work with the relevant authority. Include known approval documents and name the person responsible for unresolved checks in the project brief.
