What comes off the wall in St. Marys
St. Marys is called the Stonetown for a reason, and it changes the whole shape of the siding market here. A large share of the older housing cannot and should not be clad at all. The work is at the edges: additions, garages, rear elevations and the postwar streets outside the historic core.
What tear-off most often turns up on a St. Marys wall:
- Homeowners quoted for full wraps on designated stone properties that will not receive heritage approval.
- Moisture-holding north elevations on the valley streets.
- Cladding butted directly against coursed limestone with no flashed transition, which traps water at the joint between the two materials.
- Rear additions clad in a profile that fights the stone rather than deferring to it.
Getting a match on a St. Marys wall
The newest stock in St. Marys is 1950s–1990s (The residential streets beyond the core). Conventional bungalow and split stock where standard re-clad work applies.
Colour match is what decides whether this stays a repair. A panel that matches the original SKU still has to match a wall that has taken years of sun, and south and west elevations move furthest.

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. Marys
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. Marys is 35 km from the London base. About 35 minutes northeast of London. 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. Marys
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 makes St. Marys different from London for this work?
The Thames valley cuts through the town, so the low streets near the river hold moisture and shade longer than the higher ground. North-facing lower courses in the valley pick up staining faster than the same product would on the tableland above.
