Siding Replacement in St. Thomas: what to expect

Southwestern Ontario around St. Thomas carries a lot of older housing, and renovations here routinely open walls onto the past โ€” dated wiring, plaster, and framing that predates modern spans โ€” so good quotes carry honest contingency.

One thing we factor into St. Thomas projects: St. Thomas has been growing quickly since major manufacturing investment was announced nearby, lifting both renovation activity and contractor demand.

About St. Thomas homes

St. Thomas earned its Railway City name honestly, and the housing reflects that era โ€” sturdy century homes on tree-lined streets, still priced well below nearby London. New industrial investment has pushed the city into a genuine growth phase, with fresh subdivisions rising on the edges while older homes in the core change hands and get renovated properly for the first time in decades.

Typical projects here run from full kitchen and bathroom remodels in older brick houses to basement apartments that help carry a mortgage. If you've bought a house with potential, or you're finally updating one you've owned for years, outline the work you want done and we'll organize a free quote from renovation contractors serving St. Thomas and Elgin County.

  • Much of the older housing stock dates from the city's railway boom, so plaster walls, dated wiring, and layered flooring are common finds during demolition.
  • St. Thomas has been growing quickly since major manufacturing investment was announced nearby, lifting both renovation activity and contractor demand.
  • It remains one of the more affordable cities in southwestern Ontario, which leaves room in many budgets for larger renovation scopes.

What affects your St. Thomas siding replacement cost

What you'll invest in siding replacement in St. Thomas depends on a few real things:

  • Total wall area and the number of storeys to scaffold
  • Siding material, profile and colour โ€” premium products carry premium pricing
  • What removal reveals: hidden moisture damage adds scope once walls are open
  • Moisture history in St. Thomas homes โ€” anything that has been damp needs proper remediation before new finishes go over it, and a good quote prices that in rather than burying it.
  • Whether exterior insulation or a rainscreen assembly goes under the new siding
  • Access and disposal logistics on tight urban lots

Common questions

Do you cover all of St. Thomas?

My St. Thomas project isn't huge. Will anyone take it?
That's exactly what the quote form is for. Describe the project at whatever size it really is, and you'll get an honest price for that โ€” not pressure to grow it.
Can new siding be installed over the old siding?
Sometimes it is physically possible, but we recommend against it. Stripping to the sheathing is where the real value sits: renewing the weather barrier, flashing every opening and confirming the structure is dry. Layering new over old hides problems, creates uneven surfaces and can void manufacturer warranties on the new product.
Which siding material handles Ontario winters best?
Fibre cement and steel take freeze-thaw cycling and ice impact particularly well. Engineered wood performs strongly when detailed correctly. Vinyl remains a solid budget choice provided it is fastened loosely enough to expand and contract through large temperature swings. The installation details matter as much as the material itself.
