Sound familiar?
Which of these 6 conditions are you encountering?
Don't wait or delay. Early detection and resolution is the key to huge savings and lower costs.
Ottawa's freeze-thaw cycles and clay-heavy soil put steady pressure on every foundation in the city, commercial and residential alike.
- Water in the basement
Puddles after rain, seepage along the wall/floor seam, damp corners.
- Cracks in the foundation
Vertical, horizontal, or stair-step cracks in poured concrete or block.
- Musty smell
That heavy basement smell almost always means moisture and hidden mold.
- Visible mold
Black, green, or white growth on walls, joists, or belongings.
- Uneven floors, sticking doors
Movement upstairs often traces back to the foundation.
- Efflorescence, spalling
White chalky deposits or flaking concrete. Water is finding a way in.
Know what you're looking at
The three kinds of growth we're usually called about.
Green mold
Fuzzy green patches on joists, studs and drywall. Common after a flood or in a basement that never fully dries out.
White, flaking growth
Powdery white deposits and flaking concrete. Water is moving through the wall and leaving minerals behind as it dries.

Why Ottawa foundations struggle
Three forces working against your foundation, every single year.
Winter
The freeze-thaw cycle
Water gets into the foundation's hairline cracks in the fall, then freezes and expands them through the winter.
Spring
Runoff and drainage
Improper drainage allows water to cause more damage to the cracks as the snow melts and the ground saturates.
Leda clay
The soil under the city
Ottawa's clay swells when wet and shrinks when dry. That constant movement is what pushes on walls and shifts footings.
Why clients call us
The person on the phone is the person doing the work.
