Wall Mould Remediation, Toronto

Where the water comes from

Four usual sources in Toronto walls: a failed window or door flashing, a plumbing leak inside the cavity, ground water at the foundation wicking up the framing, and interior humidity condensing on the back of cold sheathing where the cavity is uninsulated or the vapour control has been breached.

The remediation itself is straightforward — open, remove, dry, treat, rebuild. What matters is which of the four it was, because rebuilding into an ongoing leak means doing it twice.

When this is the wrong answer

We do not do air-quality clearance testing, and we do not replace windows or repair plumbing. Where one of those is the source, that trade goes first. We will document what we found so the next trade is not guessing.
