What to know about hiring here

London combines established older neighbourhoods with extensive suburban growth, and the gap between them is wide. Areas such as Old North and Woodfield hold significant century housing with the maintenance profile that implies, while the north and northwest are dominated by construction from the last three decades with entirely different needs.

As a regional centre, London has a deeper contractor market than the smaller cities around it, which generally works in your favour: more competition, more specialisation, and a realistic chance of finding someone who has worked on a house like yours specifically.

It also functions as the trades hub for much of southwestern Ontario, so London-based contractors frequently serve St. Thomas, Strathroy and surrounding communities - worth knowing if you are outside the city and struggling to get quotes.

Century homes in the older core

Expect knob-and-tube, plaster and lath, and original single-pane windows in the older neighbourhoods. Each substantially changes renovation scope.

Heritage conservation districts

Several London neighbourhoods carry heritage designations affecting exterior work. Confirm before replacing windows or roofing material.

Student rental areas

Neighbourhoods near Western University have a large rental component, and local trades see demand spikes around turnover periods.

Deeper contractor market

More specialists here than in surrounding towns. Worth using that to find someone with direct experience of your specific job type.

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.
