Crawlspace repair in Point Douglas

Point Douglas is the oldest residential area in Winnipeg, sitting inside a tight bend of the Red River just north of downtown. Much of the housing predates 1920, and some predates 1900. Foundations from that period were rubble stone or early unreinforced concrete, built shallow, without footings as we would recognize them, and with no damp-proofing. Crawl areas are common under additions and under sections of houses that were never fully excavated.

River proximity on three sides keeps groundwater high, and the clay soil holds it against these old walls for weeks every spring. The resulting conditions are the most severe we encounter in the city: displaced and bowing stone, mortar washed out entirely in places, standing water on soil floors, rot well advanced at sill plates and post bases, and mould throughout the joist bays. In houses this old the crawlspace is frequently also the main radon entry point, with bare soil directly beneath the living space.

Work here requires judgment about what can be sealed and what must first be rebuilt. We assess masonry bearing and condition before specifying anything, and we choose moisture strategies appropriate to historic walls rather than wrapping them tight. Typically the sequence is masonry and structural stabilization, then drainage with a sump sized for sustained spring operation, then a sealed floor barrier to cut off vapour and soil gas, with perimeter insulation where the wall construction permits. Radon is tested after completion.

Point Douglas calls involve the oldest and most severe conditions we see in the city: displaced rubble stone, mortar washed out, standing water on soil floors, advanced rot at sill plates and post bases. Owners frequently call about a smell or a soft floor and are not aware of the foundation's condition until someone goes in with a light.

Our first recommendation is always masonry and structural assessment before anything is sealed, and sometimes engineering involvement, which we will say plainly. Stabilization comes first, then drainage with a sump sized for sustained spring operation, then a sealed floor to cut off vapour and radon. Perimeter insulation follows where the wall construction permits it.
