What to know about hiring here

St. Thomas has a housing stock typical of a southwestern Ontario railway city: a core of late-nineteenth and early-twentieth century homes, substantial post-war expansion, and newer subdivision development on the edges. Costs here have historically run below the larger centres, and for many trades they still do.

The significant recent change is industrial. Large-scale manufacturing investment in the area has increased demand for skilled trades considerably, and that competition for labour reaches residential work. Lead times have lengthened and pricing has firmed relative to what long-time residents expect.

For homeowners, the practical effect is that booking further ahead matters more than it used to, and that a contractor quoting immediate availability in peak season is worth asking about.

Trades competing with industrial projects

Large industrial construction draws electricians, plumbers and general labour away from residential work. Book well ahead, particularly for the compulsory trades.

Older core housing

Homes in the older neighbourhoods commonly have undersized electrical service, original plumbing and limited insulation. Budget contingency on any renovation opening walls.

Clay soils and drainage

Heavy soils in parts of Elgin County drain slowly, which matters for basement waterproofing, grading and any concrete work. Ask how a contractor is handling drainage.

Smaller contractor pool

Fewer businesses per trade than a large city, so getting three comparable quotes may mean including contractors from London or Aylmer.

Permits

Permits are issued by the municipality you live in, not the region — confirm what your project needs with your local building department. A contractor's assurance is not a substitute for their answer.
