Specifying for St. Marys conditions
What suits a wall in St. Marys:
- Fibre cement or engineered wood on additions to stone properties, where profile and mass need to sit sympathetically against limestone.
- Board and batten on rear additions and garages, which reads correctly next to coursed stone in a way that wide lap does not.
- Standard vinyl on the postwar streets outside the historic core, where no heritage constraint applies.
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.
What drives the price in St. Marys
Fibre cement carries a meaningfully higher labour cost than vinyl — heavier boards, dust control, and per-board fastening rather than hung courses.
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.

How fibre cement and james hardie siding is done properly
- Cutting generates crystalline silica dust. Score-and-snap or a dust-collecting shear is the correct method, not a dry circular saw in the driveway.
- Boards are fastened, not hung. Fastening pattern and blind-nail versus face-nail is specified by the manufacturer and it is what the warranty is judged against.
Frequently asked questions
Fibre Cement and James Hardie Siding in St. Marys
Is fibre cement siding worth the extra cost in Ontario?
It holds colour longer, will not deform in heat, and takes impact far better than vinyl. The tradeoff is installed cost and a harder repair when a board does get damaged.
What do you usually find on St. Marys homes?
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.
Do you need a permit for fibre cement and james hardie siding in St. Marys?
St. Marys is a separated town and administers its own building department independently of Perth County.
