Quote: timber windows
E.g.: Replacing timber windows while retaining the appearance of the existing openings and comparing glazing and finish options.

State whether you want timber window replacement or assessment for retention. Provide photographs of profiles, joints, opening leaves and visible defects. Describe details to preserve and expected use so the contractor can distinguish restoration, adaptation and new manufacture.
Assess retention
Buildwise’s traditional timber-window study considers improvement while preserving appearance. It does not establish your frame’s condition. Request assessment of timber and joints, then the scope of any repair.
Describe the manufacturing design
Specify leaves, profiles, glazing bars, shape and colour. Request species or system construction and factory-finished surfaces. Confirm glass and hardware compatibility. Identify bespoke historic reproduction explicitly rather than comparing it with an unspecified catalogue window.
Check building constraints
INPA supports restoration projects and advises on elements worth preserving. For a building of heritage interest, clarify status and proposals with the relevant parties before commissioning manufacture.
Organise fitting and care
Describe removal, protection of retained elements, junctions and finishes. Assign final manufacturing-measurement approval. Request care instructions for the chosen finish and repair arrangements, without a universal interval for every façade.

On quotation
Budget depends on repairing existing units, reproducing a design or supplying a new model. Compare joinery, glass, finish and fitting separately. No local average or species/triple-glazing premium is established without comparable offers.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Can only the glazing be changed?
Have frame, joints and new-glass compatibility checked. Timber alone does not establish feasibility.
Must an old window be replaced?
Request assessment and possible scenarios. No age or defect count automatically decides here.
Is painting included?
Distinguish window finishing from surrounding wall work in the quote.
Does INPA require the same model everywhere?
Check building-specific and project constraints. This guide grants no approval.
