Roof timber treatment
in Nivelles
On the building stock of Nivelles — brick terraced houses, reconstruction-era blocks, recent residential areas — roof timber treatment calls for a method that fits. Survey, curative treatment against insects and fungi, and reinforcement of weakened timber.
BeforeAfter
The context in Nivelles
Why here in particular
The old centre imposes constraints on colour and material: we always check before ordering roof covering. So we adapt the equipment and the method rather than running a standard protocol.
Roof timbers under attack are not visible from the living room. You find it by going up: frass at the foot of the rafters, exit holes, sometimes a fungal smell near an old leak.

- Full diagnosis with a survey
- Brushing and dust removal
- Injection and curative spraying
- Strengthening of the weakened members
- Treating the cause of the damp
- Photo report and product data sheet
Diagnosis
Probing with an awl, mapping the rotten areas, tracing where the damp comes from.
Preparation
Brushing, dust removal, taking off the parts that no longer hold.
Treatment
Injection into the heavy timbers, spraying to saturation over the whole.
Strengthening
Sistering or doubling up the weakened members, with plates and bolts.
Cause
We also deal with whatever wetted the timber. Otherwise it starts again.
Frequently asked questions
Roof timber treatment in Nivelles
The questions we get asked most often before this kind of job.
How long does the treatment take?
Around ten years for a curative treatment properly applied to saturation.
Do you treat dry rot?
Dry rot is another category altogether: you have to remove the source of water, cut back generously and sometimes treat the masonry. We diagnose it and point you honestly in the right direction.
Can insulation be added afterwards?
Yes, and that is the right order: treat, reinforce, then insulate. The other way round just wraps the problem up.
Do you come out to Nivelles with no extra call-out charge?
Yes. Nivelles is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
