Crawlspace repair in Norwood

Norwood sits on the east bank across from downtown, one of the older parts of the city, with housing concentrated in the 1900 to 1940 range. The Red River is immediately adjacent, so groundwater runs high and the surrounding clay holds moisture against foundations through much of the year. The foundations themselves are old — stone, early concrete, and block added later — and crawl areas are common under additions, summer kitchens and enclosed porches.

These crawl areas tend to be shallow, with bare soil floors and no vapour control, and they function as a direct connection between damp ground and the living space above. We document the usual consequences: salt deposits and mortar loss on masonry, soft wood at sill plates and post bases, mould on joists and sheathing, and air carrying moisture and soil gas upward. Radon is a specific concern in spaces like these, since Manitoba's indoor readings are among the highest in Canada and bare soil under a house is the main entry path.

Our work balances heritage construction with modern performance. We stabilize and assess masonry before sealing, keep moisture strategies appropriate for old walls, and focus on getting a continuous, sealed barrier across the soil to cut off both moisture and soil gas. Drainage goes in where groundwater is active, perimeter insulation brings the space into the conditioned envelope, and we test radon after the work so the result is verified rather than assumed.

Norwood calls usually involve both age and groundwater. Owners of century-old homes near the river report damp crawl areas under summer kitchens and enclosed porches, salt deposits on masonry, soft wood at the sill and a smell carrying upstairs. Radon questions are also common here, because bare soil under an old addition is an efficient entry route.

Our first recommendation is to seal the soil floor properly — which addresses vapour and soil gas together — while assessing the masonry before anything is fastened to it. Where groundwater is active, drainage precedes sealing. We recommend a long-term radon test before the barrier goes down, so a collection pipe can be installed underneath rather than retrofitted through a finished membrane later.
