What comes off the wall 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.
What tear-off most often turns up on a St. Thomas wall:
- 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.
Specifying for St. Thomas conditions
What suits a wall in St. Thomas:
- 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.
How siding replacement is done properly
- Sheathing repair gets priced per sheet at tear-off and shown as a separate line, not folded into the base price.
- Tear-off is the only point at which the sheathing and the water-resistive barrier can actually be inspected. Anything installed over top hides the condition instead of fixing it.
What drives the price in St. Thomas
What the crew finds once the old cladding comes off — rotted sheathing and failed wrap are the two line items that move a quote.
St. Thomas is 30 km from the London base. About 30 minutes south of London down Highbury Avenue or Wellington Road. Travel affects scheduling, not the price, and either way it is stated before you book.
Where siding replacement goes wrong
- Re-cladding over a wall that was already holding moisture, which pushes the problem into the framing.
Frequently asked questions
Siding Replacement in St. Thomas
Should old siding be removed before new siding goes on?
For a replacement, yes. Going over top hides the condition of the sheathing and the water barrier, adds thickness at every window and door, and makes any future warranty claim harder to argue.
What do you usually find on St. Thomas homes?
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.
Do you need a permit for siding replacement in 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.
