Weather exposure in St. Thomas

St. Thomas sits roughly 15 km inland from Lake Erie on the Elgin plateau. The practical effect is south and southwest driven rain: the lake-side elevation of a house here takes more wind-driven water than the equivalent wall in London, and that is where seam and J-channel detailing matters most.

That points the material choice in a specific direction:

• Insulated vinyl on the uneven older frame walls near the core, where the contoured backing hides wall irregularity.
• Fibre cement on the exposed south and southwest elevations that take the driven rain.

The housing stock in St. Thomas, and what it means for cladding

1880s–1920s — Downtown core, streets around the old Canada Southern rail lands. Railway-era workers' housing — wood frame, narrow lots, often re-clad in aluminum in the 1960s and never touched since. Tear-off here regularly finds board sheathing with gaps and no water-resistive barrier at all.

1950s–1970s — The postwar ring outward from the core. Bungalows and side-splits on wider lots. Standard aluminum and early vinyl, most of it at or past end of life.

2010s onward — Orchard Park, Shaw Valley, Harvest Run and the newer south and east subdivisions. Recent builder stock with brick fronts and vinyl elsewhere. Work here skews toward storm repair, colour-match panel replacement and gable accent upgrades.

Permits and approvals in City of St. Thomas

St. Thomas administers its own building department separately from London, so permit questions go to City Hall on Talbot Street rather than to Middlesex County or the City of London. Like-for-like siding replacement with no structural change is generally exempt, but confirm directly before scheduling — the exemption does not extend to structural work or to changes affecting spatial separation on a tight lot.

Permits and inspections for St. Thomas are handled by City of St. Thomas Building Services — 545 Talbot Street.

St. Thomas maintains a municipal heritage register, and the railway-era housing near the old Canada Southern corridor includes properties on it. Check the register before changing a street-facing elevation downtown.

What we most often find on St. Thomas walls

• Frame walls from the railway era with no water-resistive barrier behind the original cladding.
• Aluminum from the 1960s that dents rather than cracks, so hail damage presents differently than on vinyl.
• South-facing elevations showing far more UV fade than the north side of the same house, which breaks colour match on partial repairs.

Working in St. Thomas

This is a railway town, and the housing stock shows it. The tight nineteenth-century lots near the old Canada Southern corridor mean scaffold access and neighbour clearance are a real scheduling factor, not a formality — several streets have under two metres between houses.

About 30 minutes south of London down Highbury Avenue or Wellington Road.
