Wellington County • In-house crews
If the first floor in Old University, Guelph smells like a cottage in April, the crawl space is writing the script. We seal, drain, and jack — we do not “vent it more.”
Crawl Space Repair — no obligation
Guelph does not fail foundations in theory. It fails them with limestone bedrock close to grade in older wards and clay loam in the south-end subdivisions. Limestone and brick Victorian cores plus 1970s–2000s subdivisions in Kortright, Clairfields, and Westminster Woods. When we repair and encapsulate crawl spaces here, we design for that — not a generic “Southern Ontario” brochure.
Old University sits on the same limestone bedrock close to grade in older wards and clay loam in the south-end subdivisions. The housing mix is limestone and brick victorian cores plus 1970s–2000s subdivisions in kortright, clairfields, and westminster woods.
We still treat this as a Guelph job: same crews, same warranty, but we show up already knowing how Old University lots drain (or don’t).
Free inspection. Photos. A number. No hard close.
Old codes vented crawl spaces. Summer humidity then condenses on cold wood. Mold and rot follow. In Old University, Guelph, that plays out against limestone bedrock close to grade in older wards and clay loam in the south-end subdivisions.

Wet wood sags. Floors bounce. We sister, jack, and put the load on something that is not rotting. In Old University, Guelph, that plays out against limestone bedrock close to grade in older wards and clay loam in the south-end subdivisions.
We crawl it. Moisture readings, wood condition, pests, standing water, and insulation that became a sponge.
Standing water gets a drain and sump before any plastic goes down. Encapsulation over a pond is theatre.
Heavy vapor barrier on walls and floor, sealed seams, closed vents, conditioned or dehumidified air.
Adjustable steel jacks where joists have sagged. We do not crank a 90-year-old house 2 inches in an afternoon.
You should smell nothing. That is the test.
