★★★★★ “Thank you to Paul. We have peace of mind.” Allen, homeowner
Is your home on Quebec’s new flood map? Aquaverter will tell you.
We call you within 24 hours. Not a call centre. The founder, Paul St-Denis, calls you himself.
Free. No obligation. No sales pitch. If it’s not for you, Paul says so.
“For the first time in years, I won’t be constantly worrying every time it rains.”
Melissa, St-Léonard. Flooded three times before Aquaverter.“Very happy with the system and the team behind it. Talking with the owner is easy and he answers every question. Fast response, fast installation.”
Pierre-André, homeowner. Translated from French.“Paul took the time to make sure everything was solid and done right. I 100% recommend Aquaverter.”
Martin, Rivière-des-Prairies. Translated from French.What happens after you submit the form
- Paul calls you within 24 hours. The founder. Not a rep.
- He comes to your house. Garage, doors, window wells. He checks every way water gets in.
- You get a straight answer and an exact price. If it’s not for you, he tells you that too.
Is this your house?
- Water came in under the garage door on June 20, or on Canada Day. Or the storm before that.
- Your basement door or entry sits lower than the street.
- Your window wells fill up when it pours.
- Your sump pump is the only thing between you and the water.
You own the place. You’d rather pay once than clean up again.
If that’s you, Paul can help. If it isn’t, he’ll tell you.
A barrier that’s already on your door when the storm hits.
Sump pumps work until they don’t. Aquaverter stops water before it enters your home.
- Mounts permanently on your garage door, entries and window wells.

What a flood costs. What a barrier costs.
The average basement flood claim in Canada. Insurance Bureau of Canada. Every flood.
A standard garage door barrier, installed. Once. Cheaper than the cleanup. The mold. The claim.
- Montreal, June 20, 2026. Over 100 mm of rain hit Pierrefonds, DDO and Pointe-Claire in a single afternoon. Hundreds of homes flooded. Over 20,000 lost power overnight.
- Ottawa, July 1, 2026. A record 118 mm fell on Canada Day. More than 4,500 households reported flooded basements. Over 36,000 lost power.
- Quebec’s new flood maps, rolled out since March 2026, added 30% more properties to designated risk zones. If your address is on the list, your insurer already knows.
- Flooded homes sell for 8.2% less. 44% fewer even make it to market.
Every Aquaverter system is custom-built to your opening, so Paul gives you the exact number after the free assessment. Montreal’s RénoPlex program can cover up to 50% of the cost of certain flood protection work on buildings of 1 to 5 units. You apply before the work starts. Paul tells you if your home may qualify.
