Quote: roof frame strengthening or repair
E.g.: sagging or cracked beam after damage or overload
Describe deformation, damaged timber, an earlier leak or a project adding loads. Provide existing documents and photographs without exposing yourself to obtain them. If the structure appears unstable or deteriorates rapidly, move away and arrange urgent assistance; do not wait for quote comparison to secure the area.
Commission a suitable assessment
The IBC guide presented by CODIFAB stresses that no single diagnostic brief suits all existing timber structures. Define inspected areas, required documents, investigations and report limits. Have inaccessible areas identified rather than implicitly treated as sound.
Connect the defect to its cause
Provide the chronology of leaks, alterations, added loads and previous repairs. Request a map of affected members and supports. Separate biological activity, moisture and structural resistance: removing insects or leaks does not prove the wood retains its original capacity.
Compare defined solutions
Specify retained, strengthened or replaced work with drawings and justification. Clarify related changes to supports or the building. Do not choose a technique solely by beam count or a generic doubling recipe.
Establish working conditions
Identify who designs temporary support, restricted areas and conditions for continued occupation. Address access, construction loads and rain protection. Do not remove a support or prop yourself.
Keep repair evidence
Request final member identification, updated drawings, useful pre-closure photographs and handover records. Clarify follow-up and later load additions. Distinguish written contractor commitments from product characteristics alone.
Indicative prices in Luxembourg
On quotation
The price must relate to a designed solution following assessment. Separate investigation, calculations, temporary safety measures, repair and reinstatement. The number of visible members alone cannot classify a project as a simple or major repair.
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
Does a crack require beam replacement?
Appearance alone cannot decide. Have the member, connections and context assessed.
Is an engineer only needed above a certain member count?
No member-count threshold is given here. Define expertise and investigation around the actual issue.
Can I stay beneath the work area?
Do not assume so. Site managers must establish access and occupation restrictions.
Does timber treatment replace strengthening?
No. Treating an infestation and establishing structural resistance answer different questions.
