The Hamilton home energy guide
Hamilton's housing tells the city's story: century brick downtown, dense post-war neighbourhoods built for steelworkers, and newer suburbs climbing the escarpment. Each era fails differently — and the audit tells you which failure you own.
The housing stock, read like an auditor
Lower Hamilton runs to pre-war brick with empty or minimal wall insulation and original attics. The east end and Mountain filled in through the 1950s–70s with bungalows and back-splits — thin batts, R-10 to R-20 attics, unfinished basements. Ancaster, Dundas, and Waterdown add 1980s–2000s stock where ventilation and duct balance, not insulation depth, are the usual complaints. Lake and escarpment effects mean wind-driven leakage matters more here than the thermometer alone suggests.
What audits find in Hamilton
- Empty brick-veneer wall cavities in pre-1960 homes — drill-and-fill candidates
- Attic top-ups from R-15 to R-60 as the city's most consistent payback
- Basement moisture that must be addressed before insulation in the older lower city
- Wind-exposed escarpment homes where air sealing outperforms its usual returns
- Aging mid-efficiency furnaces due for the heat-pump-or-hybrid decision
Tests to ask for by name
- Blower door test — the leakage number that reorders your plan
- Infrared scan — finds the empty walls without opening them
- CSA F280 heat-loss calculation — before any heat pump quote
- Radon test — Health Canada recommends it for every home
Run the planner for the full test list matched to your house — it carries into your audit request automatically.
The rebate angle
Hamilton is one of Ontario's better-supplied audit markets: Green Venture, the local non-profit service organization, works alongside province-wide firms — comparing a community quote against a commercial one is realistic here. Home Renovation Savings covers the standard stack: $600 assessment rebate, insulation to $7,700, heat pumps to $12,000.

Local questions
My Hamilton house is brick — can the walls even be insulated?
Depends which brick: brick veneer over frame usually has a cavity that can be dense-packed; solid double-brick can't be filled and needs interior or exterior strategies. The audit's thermal scan tells you which you own before you spend a dollar.
