Sherwood Park basements face two big flood seasons: the spring thaw, when months of snow melt in a few warm weeks and the ground is still frozen, and summer thunderstorms, when intense downpours overwhelm storm and sanitary sewers across the Edmonton region. Add aging weeping tile in older neighbourhoods and sump pumps in newer ones, and a wet basement is one of the most common calls we get. Here’s what to do, step by step.

Step 1: Stay Safe
- Don’t step into water that may be touching outlets, extension cords, the furnace or the water heater.
- If you can reach the electrical panel without standing in water, shut off power to the basement. Otherwise, call an electrician or your electricity provider.
- If you smell gas, leave the house and call ATCO’s emergency line from outside.
- Treat water coming up a floor drain as sewage. Keep kids and pets away.
Step 2: Find and Stop the Source
| Where is the water coming from? | Likely cause | What to do |
|---|---|---|
| Floor drain | Sanitary sewer backup | Stop using all water in the house; call for Category 3 cleanup |
| Floor-wall joint or cracks | Groundwater, spring melt, failed weeping tile | Check the sump pump; move snow and water away from the foundation |
| Sump pit overflowing | Pump failure or frozen discharge line | Check breaker, float and discharge line |
| Ceiling or wall | Burst pipe, upstairs leak, ice dam | Shut the main water valve |
| Around the water heater or washer | Appliance failure | Shut the appliance’s supply valve or the main |
Step 3: Document and Report
Take wide photos and video of each wet area, the water level on walls, the source and damaged belongings. Then call your insurer to start a claim. Our Alberta insurance guide explains what’s typically covered.
Step 4: Get Professional Extraction Started
Call a water damage restoration company in Sherwood Park. Technicians extract standing water, map moisture with meters and thermal imaging, remove what can’t be saved (usually carpet underlay, the bottom of drywall and wet insulation), apply antimicrobial and set up industrial drying equipment.
Step 5: Protect What You Can
- Move furniture, electronics and boxes to a dry floor.
- Put foil or blocks under furniture legs that can’t be moved.
- Get photos and documents into sealed bags; freeze them if they’re soaked.
- Run the furnace fan only if the furnace and ductwork weren’t touched by water.
Why Sherwood Park Basements Flood
Spring snowmelt
Snow piled against the foundation melts while the ground below is still frozen, so water can’t soak in and runs toward the house instead. Clear snow at least a metre from the foundation in late winter and keep downspout extensions on.
Summer storm sewer backups
Heavy rain can surcharge the sanitary system and push sewage up floor drains. A backwater valve is the key protection. See sewer backup cleanup and prevention.
Weeping tile and sump issues
Older homes may have clogged or collapsed weeping tile; newer homes rely on sump pumps whose discharge lines can freeze in winter.
Plumbing failures
Burst pipes in cold snaps, failed water heaters and washing machine hoses. See frozen and burst pipes.
How Long and How Much?
Drying typically takes 3–5 days (full timeline), and a finished basement flood commonly costs $8,000–$20,000 (cost guide).
