Compare complete specifications
Identify sections, species or timber product, cladding, finish, glazing and roof. Compare equal use and performance. Material price does not universally rank systems or prove aesthetic superiority.
Include installation and finishes
Price survey, design, excavation, foundations or strengthening, fabrication, transport, installation, temporary weather protection and junctions. Separate joinery, shading, services and flooring. Identify exclusions and investigations needed before a firm price.
Compare aftercare
Request maintenance conditions, surface access, warranties and repair service. Price a specific maintenance task if required rather than inventing fifteen-year totals. Check taxes, options and payments. Timber sourcing certification does not establish grant eligibility.
