Know the neighbourhood
Streets running along the Credit River valley, holding a mix of 1970s through 1990s housing. The valley dominates everything here. Elevation change across a single street is often enough to decide which houses flood and which stay dry.
East of the Credit River around Creditview Road, generally south of Eglinton Avenue with Burnhamthorpe Road West and Mavis Road crossing the area.
1970s–1990s
Detached two-storeys and backsplits, many with walkout or lookout basements
Homes built on the slope toward the valley often have walkouts at the back and a full basement at the front. That makes for bright, usable basement space, and a direct path for water that runs down the lot. Many houses have had their basements finished more than once, so we often find two layers of flooring or walls built over older ones.
Everything here drains toward the Credit River valley, and the ground can drop noticeably from the front of a lot to the back. Runoff from the street and from neighbours uphill crosses back yards on its way down. Lots on the lower side of a street collect it at their walkout doors and window wells. Sump pumps on these streets work harder than most, and where they discharge matters as much as whether they run.
Local conditions
These three conditions decide where we look first on a Creditview call, what can be saved and where the drying equipment goes.
Water moves downhill toward the valley and finds the lowest opening on its way there. Window wells and walkout doors are the usual entry points.
Grade-level doors and larger below-grade windows give surface water a direct route inside that a standard basement never offers.
Pumps discharging too close to the foundation simply recirculate the same water. This is one of the most common faults we find on these streets.
A call we get often in Creditview
A call we get often here: during a heavy summer storm, water runs down the back yard, pools at the walkout patio and comes in under the basement door. The carpet or laminate nearest the door gets soaked first, and the water spreads under the baseboards toward the front of the house. We extract it, dry the floor and walls and look at how the patio slopes and where the downspouts and sump discharge. Fixing the route the water took is what stops it from coming back.
Through the year
Thunderstorms send runoff down sloped back yards faster than patio drains and walkout thresholds can handle.
Snow piled against walkout doors and lookout windows melts straight into the basement when the thaw comes.
Leaves clog the drain in front of the walkout patio, so the next heavy rain pools against the door instead of draining away.
Sump discharge lines freeze outside when they run along the surface, and the pump keeps cycling water that has nowhere to go.
Most requested here
Walkout and lookout basements on the valley slope are where runoff ends up during heavy rain.
Basement Flood CleanupLayered basement finishes from repeated renovations hide moisture that needs targeted drying, not just surface fans.
Structural Drying & DehumidificationRepeated small water entries at the same door or window can leave mould behind trim and under flooring.
Mould RemediationBefore it happens
Run the sump pump discharge well away from the house and downhill, not out beside the walkout patio.
Clear the patio or area drain in front of a walkout door every fall and after big storms.
Fit clear covers on lookout and basement window wells on the uphill side of the lot.
Shovel snow away from walkout doors and lower windows before a thaw.
Local questions

(877) 738-2893A walkout sits at the bottom of the lot, so runoff from above ends up at that door. If the patio slopes toward the house or its drain is blocked, water pools against the threshold and finds a way under it. Regrading the patio and keeping the drain clear usually solves it.
Not necessarily. Most homes on these streets sit well above the river itself, and their water problems come from runoff and the slope, not from the river rising. Credit Valley Conservation maps the regulated areas if you want to check your property.
It can be. Water gets trapped between the layers and the subfloor stays wet long after the top looks dry. We usually remove the top layers to dry the concrete properly before anything new goes down.
