Leak detection
in Overijse
In the heart of the Druivenstreek, Overijse spreads across wooded slopes where the houses cling to the hillsides, between old grape greenhouses and recent villas. Pinpointing where an infiltration really starts: thermal camera, progressive water testing, smoke test if needed.

The context in Overijse
Why here in particular
What changes in Overijse is the context: post-war villas on sloping ground, old greenhouses, complex roofs with multiple pitches. The tree cover keeps the roofs damp and the gutters fill twice a year rather than once.
The stain on the ceiling is almost never under the hole. Water runs along a rafter, follows a purlin and drops three metres further on. Looking in the wrong place costs more than looking methodically.

- Methodical water testing
- Written report with photos

Findings
History, photos, the conditions in which the leak appears. Rain driving in and rain falling straight down do not point to the same places.
Inspection
Loft, underlay, flashings, roof valleys, chimney stacks, roof window surrounds.
Thermography
Infrared camera to map out the damp area inside the wall.
Water test
Progressive wetting zone by zone, from the bottom upwards, until the leak reappears.
Report
Origin, cause, photos, and the costing for the repair.
Frequently asked questions
Leak detection in Overijse
The questions we get asked most often before this kind of job.
Will my insurance cover it?
Often the search and the damage, rarely the cause if it comes down to a lack of maintenance. The written report serves as evidence for your file.
Do you repair straight away?
If it is a flashing, a tile or a joint, yes, the same day. If it is a roof valley or an underlay, it becomes a job to schedule.
Does condensation count as a leak?
No, and it happens often: a badly ventilated loft, a punctured vapour barrier. The treatment is nothing like the same, and we tell them apart before invoicing a pointless repair.
Do you come out to Overijse with no extra call-out charge?
Yes. Overijse is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
