Frequently Asked Questions
How do I know my weeping tile is finished?▾
Through a camera inspection. It shows roots, collapse, blockages and deposits. It is the only way to decide on facts rather than symptoms.
What is iron ochre?▾
An orange deposit, linked to bacteria present in some soils, that gradually clogs drains. An affected drain needs regular maintenance, and sometimes a system designed to be cleaned.
Does my backwater valve work?▾
It must be accessible and inspected periodically. A fouled flap no longer closes, and the valve stops doing its job during a storm.
Can moisture be solved without digging?▾
Sometimes. Extending downspouts and correcting the lot slope are enough in some cases. A good diagnosis always starts there.
How do I verify a contractor is licensed?▾
Ask for the RBQ licence number and search the Régie du bâtiment du Québec public registry.
Drainage in Montréal: what to know
Residential drainage covers everything that moves water away from the building: weeping tile at the footing, gutters, lot slope, backwater valve and sump pump.
Diagnosis before work
A damp basement does not automatically mean a drain to replace. A camera inspection shows the pipe's real condition: roots, collapse, blockage or iron ochre deposits. That step costs a fraction of excavation and prevents digging for nothing.
Iron ochre
In some sectors, an iron-related bacteria creates an orange deposit that clogs drains. The diagnosis changes everything: a drain affected by ochre needs regular maintenance, not only replacement.
Backups
A backwater valve protects against sewer backup during heavy storms. It must be accessible and inspected periodically, otherwise it eventually stops closing.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
