Flood response after an atmospheric river in Greater Vancouver

Basement taking water? Call now if it is active.

Why atmospheric rivers are different

Days of rain, saturated ground, and overloaded storm systems — not a single burst pipe

Surge capacity

We prioritize active flooding and return for monitoring as the event continues.

Basements first

Sump failures and seepage are the typical call. Pumps and drying staged for GVA homes.

Dirty water

Yard and drain water is sanitized. We do not treat it as clean Category 1 by default.

What we see during an atmospheric river

The losses that spike across the GVA

Basement seepage

  • Weeping tile surcharge
  • Window wells overflowing
  • Slab moisture into finishes
  • Crawl-space flooding

Drains and sumps

  • Pumps running dry or failing
  • Municipal surcharge
  • Backwater into floor drains
  • Power loss mid-storm

Roofs and attics

  • Prolonged saturation of membranes
  • Gutter and downspout overflow
  • Attic wetting and insulation
  • Follow-on mould risk

After the rain stops

  • Full dry-out, not a fan overnight
  • Check for secondary mould
  • Waterproofing upgrades
  • Rebuild of damaged finishes

Respond through the event. Dry after it.

During the river we extract and stabilize. When rainfall eases, we complete drying, inspect for hidden moisture, and rebuild. Waiting until “the storm is over” often means a wet structure for days.

  • Dispatch while water is still entering if it is safe
  • Pump and extract; protect dry rooms
  • Map moisture after the event peaks
  • Dry to standard, then waterproof and rebuild

Atmospheric river flood response in Greater Vancouver

Atmospheric rivers dump extraordinary rain on already-wet soil. Richmond lowlands, Burnaby slopes, and North Shore run-off all show up in our dispatch board the same week. Call early — crews book out when the whole region floods.

Shield treats these as flood restoration jobs with weather documentation. If your basement floods every Pineapple Express, ask about waterproofing after this dry-out.

FAQ

Atmospheric Rivers FAQ

Shield — atmospheric rivers across Greater Vancouver.

What is an atmospheric river loss?

Multi-day extreme rain that saturates soil and overwhelms drains and sumps — often basement seepage, window wells, and roof saturation across the Lower Mainland at once.

Should I call during the rain or after?

Call while water is entering if it is safe. Waiting until the event ends can leave a wet structure for days. We extract first, then complete drying after rainfall eases.

Do you waterproof after repeated Pineapple Express floods?

Yes. After this dry-out we can specify interior barriers and drainage upgrades so the next atmospheric river is not a third claim.

Which areas do you serve?

Yes. We serve Vancouver, West Vancouver, North Vancouver, Burnaby, Richmond, New Westminster, Surrey, Coquitlam, and surrounding Greater Vancouver communities within ~50 km.
