I'm very satisfied with my flood barrier installation. Paul took the time to make sure everything was solid and done right. I 100% recommend Aquaverter. The service was impeccable -- attentive to the customer's needs and very friendly. I loved my experience with them.

August 9, 2024. Debby dropped 188 millimetres of rain on the Vallée-du-Richelieu. Chambly. Carignan. Saint-Jean. Vaudreuil. All of it, at once. Your sump pump ran. Maybe your sandbags held. Maybe they didn't.
Either way, the second wave is already forming upstream. The ground is saturated. More rain is coming this week. The municipalities are doing what they can. But what protects your door is what's on your door.
That's the Insurance Bureau of Canada's number. Not a projection. What a single basement flood actually costs Canadian homeowners today.
And Quebec's new flood maps, rolled out since March 2026 added 30% more properties to designated risk zones. If your address is on the new list, your insurer already knows. Premiums climb. Coverage gets restricted. Some policies won't renew at all.
The Haut-Richelieu remapping hasn't even been published yet. That's coming after 2026.
Flooded homes sell for 8.2% less. 44% fewer homes in flood-affected areas even make it to market.
That's not your neighbor's problem. That's your equity.
100% successful testing results. Across five residences in Rivière-des-Prairies.
Watertight performance certified through independent testing carried out by a third-party laboratory, with verified sealing for long-term reliability in harsh climates.
