Quick answer: Hamilton has a large stock of older, pre-war homes in the lower city, and many of their attics have little insulation, old vermiculite or tight 1.5-storey spaces. Pro Home Insulation checks for these issues first, then insulates to at least R-50. Starting from R-12 or less, you may get up to $1,250 back through Ontario’s Home Renovation Savings Program, currently scheduled to run until March 31, 2027. Amounts can change.

7 things that make Hamilton attics different
- Pre-war homes in the lower city. Neighbourhoods like Kirkendall, Durand, Crown Point and Gibson have many homes built before the Second World War, often with minimal insulation.
- 1.5-storey homes with knee walls. Low attic spaces beside upstairs bedrooms are hard to reach and often leak heat in winter and gain heat in summer.
- Vermiculite. Homes insulated before 1990 may have vermiculite, which should be treated as if it contains asbestos until tested.
- Knob-and-tube wiring. Some older homes may still have it, and it should not be buried under new insulation without an electrician’s review.
- Postwar bungalows on the Mountain. Many 1950s and 1960s homes above the escarpment have shallow attics with old batts.
- Newer subdivisions in Stoney Creek, Binbrook and Waterdown. These attics are usually in better shape, but settling and vaulted ceilings are common.
- Wildlife. Raccoons and squirrels are common in older, treed neighbourhoods and can contaminate insulation.
How to look at an older Hamilton attic safely
Many older homes have a small hatch in a closet ceiling, or no full attic at all above the second floor. Use a flashlight from the hatch before you climb in.
If you see grey-brown, shiny, pebble-like granules, stop. Do not touch, sweep or vacuum them. If you see old cloth-covered wires on porcelain knobs, note it for your assessment. For a general walkthrough, see how to check attic insulation R-value.
Rebate tiers for Hamilton homes
| Attic before upgrade | Upgrade to at least | Maximum rebate |
|---|---|---|
| R-12 or less | R-50 | up to $1,250 |
| Above R-12 to R-25 | R-50 | up to $1,000 |
| Above R-25 to R-35 | R-50 | up to $800 |
| Cathedral/flat roof, R-25 or less | R-28 | up to $750 |
| Cathedral/flat roof, R-12 or less | R-20 | up to $650 |
The rebate is 50% of the after-tax insulation cost, up to the tier maximum. Amounts can change and funding is first-come, first-served. Read more on our Ontario attic rebate page and rebates hub.
What the data says about older homes
- In Ontario, nearly 1.2 million residential properties were built in 1960 or earlier (Statistics Canada).
- NRCan estimates the yearly cost of air-leakage heat loss for a 1950s home at about $390 on natural gas or $860 on electricity (Natural Resources Canada).
- Vermiculite from the Libby mine may contain amphibole asbestos and was used until 1990 (Health Canada).
- Going from R-8 to R-50 cuts heat flow through the insulation layer by about 84%, simplified (1 − 8/50).
- A basement can account for about 20% of a house’s heat loss (Natural Resources Canada).
How Hamilton home types compare
| Home type | Common areas | Typical attic issues | Usual approach |
|---|---|---|---|
| Pre-war 1.5 or 2-storey | Kirkendall, Durand, Crown Point, Westdale | Little insulation, vermiculite, knob-and-tube, knee walls | Safety checks first, then removal or top-up |
| Postwar bungalow | Hamilton Mountain, Westcliffe | Old batts, low R-value, blocked soffits | Air seal, baffles, blown top-up |
| Newer subdivision | Stoney Creek, Binbrook, Waterdown | Settled fill, vaulted ceilings | Top-up, cathedral assessment |
Our process for older Hamilton homes
- Safety screen. We check for vermiculite, knob-and-tube wiring, mould and animal waste before anything else.
- Plan the sequence. If needed, vermiculite removal or animal feces removal comes first.
- Air seal. We seal the top of interior walls, chimneys and chases with air sealing.
- Address knee walls. Where access allows, we insulate and seal knee-wall areas.
- Insulate to R-50. Blown insulation goes in evenly, with baffles at the eaves.
- Hand over documents. You get the invoice and details for your rebate submission.
Older-home attic checklist
- Do not disturb any granular insulation until it is tested
- Note any old cloth-wrapped wiring you can see
- Check upstairs knee-wall doors for drafts
- Look for droppings, nesting or chewed material
- Confirm whether the home has received an attic rebate before
Example project (illustrative)
example — not a specific customer.
A 1925 1.5-storey home in Kirkendall has about R-8, partly vermiculite. Testing and removal are done first by qualified professionals. Then the attic is air sealed and insulated to R-50.
- After-tax insulation cost (insulation only): $3,400
- 50% of cost: $1,700
- Tier maximum (R-12 or less, to R-50): $1,250
- Estimated rebate: $1,250 (the cap applies)
- Net insulation cost: $3,400 − $1,250 = $2,150
Vermiculite removal is a separate cost and is not included in this rebate math.

Safety triage: what to do before any insulation work
Use this order. Each step must be cleared before the next.
| Step | What to check | If found |
|---|---|---|
| 1 | Vermiculite | Stop. Test and use qualified professionals for removal |
| 2 | Knob-and-tube wiring | Electrician review before insulating over it |
| 3 | Animal waste or nests | Remove, sanitize, seal entry points |
| 4 | Mould or wet wood | Fix moisture source, then mould remediation |
| 5 | Blocked soffits | Install baffles before insulating |
Only once all five are clear should new insulation go in.
Frequently asked questions
My Westdale home has no insulation in parts of the attic. Is that normal?
It is common in homes of that age. Many older Hamilton homes were built with little or no attic insulation, which usually places them in the R-12 or less tier at up to $1,250 back.
Is vermiculite removal covered by the rebate?
The rebate is based on the after-tax insulation cost. We list removal and insulation separately on your quote so the rebate submission is clear. Check the program terms for what counts.
Can you insulate a 1.5-storey home’s knee walls?
Often, yes. Knee-wall spaces may be insulated and air sealed through small access doors. Some homes need spray foam or dense-pack in tight areas.
Do newer Binbrook or Stoney Creek homes need an upgrade?
Some do. Settled insulation or thin edges can drop the R-value below 50. A measurement will tell you whether a top-up and rebate make sense.
Is Hamilton covered by Enbridge Gas for the program?
Homes heated with Enbridge natural gas are eligible, and so are homes heated with electricity, oil, propane or wood. You must own the home.
How long does an older-home job take?
Simple top-ups often take a day. Jobs with vermiculite, pest cleanup or knee walls take longer, and your quote will show the expected timeline.
