Siding Contractor St. Marys

What we most often find on St. Marys walls

• 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.

Working 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.

About 35 minutes northeast of London.

Weather exposure in St. Marys

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.

That points the material choice in a specific direction:

• 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 housing stock in St. Marys, and what it means for cladding

1850s–1900s — The limestone core. This is the town's defining stock, and most of it is stone, not clad. Siding work here is confined to rear additions, gable infill, soffit, fascia and outbuildings — a full wrap is usually neither wanted nor permitted.

1950s–1990s — The residential streets beyond the core. Conventional bungalow and split stock where standard re-clad work applies.

St. Marys has one of the densest concentrations of designated limestone buildings in the region. Any change to a street-facing elevation on a designated property needs heritage approval before work starts, and a proposal to clad over exposed limestone will usually be refused outright.
