Leak detection
in Sint-Pieters-Leeuw
Open exposure to the west wind wears the verges and regularly tears off badly bedded ridge tiles. That is why leak detection comes back so often in our schedule in Sint-Pieters-Leeuw.

The context in Sint-Pieters-Leeuw
Why here in particular
What changes in Sint-Pieters-Leeuw is the context: brick terraced houses, Pajottenland farms, estates from the 1980s. Open exposure to the west wind wears the verges and regularly tears off badly bedded ridge tiles.
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.

Frequently asked questions
Leak detection in Sint-Pieters-Leeuw
The questions we get asked most often before this kind of job.
Do you have to wait for rain?
No, the water test reproduces rain in a controlled way. It is actually more precise.
Do you come out for emergencies?
Yes: tarpaulin or temporary repair first, full diagnosis afterwards, calmly.
And if you do not find it?
That happens with a leak that only shows up in a sustained westerly. We come back when conditions are right and do not re-invoice the search.
Do you come out to Sint-Pieters-Leeuw with no extra call-out charge?
Yes. Sint-Pieters-Leeuw is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
