Hamilton • In-house crews
If the first floor in Dundas 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
Dundas does not fail foundations in theory. It fails them with valley clay at the base of the escarpment that stays saturated after rain. Heritage downtown streets, hillside lots, and 1960s–80s pockets near University Gardens. When we repair and encapsulate crawl spaces here, we design for that — not a generic “Southern Ontario” brochure.
Dundas also deals with Spencer Creek and Cootes Paradise moisture. Combined with valley flooding, hillside frost heave, and old stone/rubble foundations, small cracks and damp corners become five-figure problems if you wait for “a dry summer.”
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 Dundas, that plays out against valley clay at the base of the escarpment that stays saturated after rain.
Uncovered soil pumps moisture into the house. Up to half of the air on the first floor can come from below. In Dundas, that plays out against valley clay at the base of the escarpment that stays saturated after rain.
Wet wood sags. Floors bounce. We sister, jack, and put the load on something that is not rotting. In Dundas, that plays out against valley clay at the base of the escarpment that stays saturated after rain.
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.

Same service, local soils. If your street is not listed, we still go — Dundas is not that big.
Sealing vents and covering soil and walls with a heavy vapor barrier so the house is separated from the earth.
A large share of first-floor air comes from the crawl space. If it is wet down there, you live with it upstairs.
Sealed crawl spaces stop the HVAC from conditioning a swamp. Bills usually drop; comfort always improves.
Usually yes, sized for the space, so humidity stays below mold range.
Yes — steel support jacks and joist repair. We lift slowly and stop at structurally honest.
We typically reply the same business day.
