Quote: timber assessment and roof-frame treatment
E.g.: roof frame attacked by wood-boring insects or dry rot
Describe signs, changes and known leaks without scraping or applying products before the visit. Request diagnosis before selecting a method. Holes, dust, stains or threads alone do not establish species, current activity or timber strength.
Define assessment limits
Identify examined areas, confirmed or suspected organism, activity signs and uncertainty. Ask about further analysis. Biological diagnosis and strength assessment answer different questions; allocate each.
Address moisture causes
Buildwise stresses moisture-source diagnosis before renovation. Investigate leaks, condensation or other sources and coordinate correction with timber work. Define drying checks and monitoring before closing finishes.
Justify method and product
Explain fit to diagnosis and exclusions. Luxembourg’s Environment Administration requires relevant notification or authorisation for biocides used locally. Request exact product and confirmation of intended use; insecticide or fungicide alone is insufficient.
Plan occupancy
Obtain written protection, ventilation, re-entry for people and animals, and belongings instructions. Regulated labelling includes precautions and, where relevant, re-entry conditions. No universal waiting period replaces product and site requirements.
Separate treatment and repair
Where capacity is uncertain, assess structural measures before modification or loading. A product cannot replace necessary strengthening. Request final report, treated areas, references, monitoring and contract commitments.
Indicative prices in Luxembourg
On quotation
Separate cause investigation, identification, access, selected work and possible timber repair. Floor area is not necessarily treated surface. Define quantities, any necessary product and monitoring; assume neither blanket preventive treatment nor uniform guarantee.
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
Do holes prove active attack?
Not alone. Assess signs, change and further checks.
Always treat during renovation?
Justify need by timber, condition and exposure; an open roof alone does not require a product.
Does treatment restore strength?
Do not assume so. Assess capacity and repair needs separately.
Does every guarantee last a decade?
No uniform period is stated here. Ask about scope, conditions and contractual remedies.
