The local factors behind wett inspection in St. Catharines
The difference between a $200 service call and a $6,000 rebuild in St. Catharines is usually about eighteen months of ignoring a small symptom.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a St. Catharines problem that looks like a chimney fault but starts elsewhere in the building.
Infill and renovation work in St. Catharines frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Martindale, Ridley, Grapeview, Lakeshore and Secord Woods, the housing stock changes street by street, and the correct method changes with it. A century home with a soft-brick stack does not get the same treatment as a 2010 build with a factory-built vent — using one method on both is how systems get damaged.
If you live anywhere near the Welland Canal, the practical takeaway is that a wett inspection visit should start with an assessment, not a tool. Any crew that begins work before telling you what they found is guessing on your behalf.
