Halton • In-house crews
If the first floor in Mountainside, Burlington 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
Burlington does not fail foundations in theory. It fails them with Halton clay that locks moisture against foundations, especially in Millcroft and Mountainside. 1960s–80s ranchers, lakeshore lots, and 1990s–2000s subdivisions in Alton, Tyandaga, and Millcroft. When we repair and encapsulate crawl spaces here, we design for that — not a generic “Southern Ontario” brochure.
Mountainside sits on a grade toward the lake. Hydrostatic pressure on the downhill wall is the usual failure point.
We still treat this as a Burlington job: same crews, same warranty, but we show up already knowing how Mountainside 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 Mountainside, Burlington, that plays out against Halton clay that locks moisture against foundations, especially in Millcroft and Mountainside.
Uncovered soil pumps moisture into the house. Up to half of the air on the first floor can come from below. In Mountainside, Burlington, that plays out against Halton clay that locks moisture against foundations, especially in Millcroft and Mountainside.
Wet wood sags. Floors bounce. We sister, jack, and put the load on something that is not rotting. In Mountainside, Burlington, that plays out against Halton clay that locks moisture against foundations, especially in Millcroft and Mountainside.
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.
