Call Now, 24/7 Flood Response in Ottawa
Water in your basement right now? Call us, we answer 24 hours a day, every day. A real person picks up, not a callback queue, and we get a crew moving while other companies are still listening to your voicemail.
We don’t just pump it out and leave. We dry it properly, remove the mold, rebuild the basement back to finished, and fix the cause so it can’t happen again. And we move fast for a reason: mold can begin to take hold within a day or two of standing water, so getting the space extracted and dried quickly is what keeps your family safe and your costs down.
Our Full Flood-to-Finished Path
Most flood companies stop at cleanup. We take you the whole way, one team, one accountable path, from the night it floods to the day it’s finished and dry.
-
Emergency extraction & drying
We answer 24/7, pump out the water, and dry the structure properly, extraction, air movers, and moisture testing, not surface mopping.
-
Mold remediation
We remove and remediate mold before any rebuilding, so the finished basement is genuinely safe, not just dry-looking.
-
Reconstruction
We rebuild the drywall, flooring, and finishes back to a finished, code-correct basement.
-
Waterproofing & prevention
Finally we fix the cause, backwater valve, sump, drainage, or waterproofing, so it can’t happen again.
How We Stop It From Happening Again
Recovering from a flood is only half the job, the other half is making sure it never recurs. Depending on how the water got in, that means a backwater valve to stop sewer backup, a sump pump (often with a battery backup), repaired weeping tile and drainage, or interior or exterior waterproofing.
We build in redundancy on purpose, so one failure doesn’t flood you again. And several of these measures qualify for the City of Ottawa’s protective-plumbing rebate, which lowers your net cost, so we’ll point you to what you can claim.
Interior vs Exterior Waterproofing & Damp Proofing
Exterior waterproofing excavates down to the foundation and seals it from the outside, the most complete defense, and the right call for persistent foundation leaks. Interior waterproofing manages water that gets in, routing it to a sump via interior drainage; it’s less invasive and often the better value. Damp proofing handles humidity and minor moisture, not active water. After we find the actual source, we recommend the method that fixes it, not the most expensive one.
Insurance & Ottawa’s Flood Grants and Rebates
Floods come with paperwork, and we help you through it. We document the damage for your insurer, talk you through what is and isn’t typically covered, and point you to the City of Ottawa’s flood relief and protective-plumbing rebate programs. You shouldn’t have to fight the claim and the cleanup at the same time.
