    Home Age Risk Profile

    Answer a few questions about the home and what records exist. You will get a prioritised list of things to investigate — not a diagnosis, and not a claim about what your house contains.

    Step 1 of 4

    1 — The property

    Use the assessment roll or title if the listing is uncertain.

    2 — Known renovations

    Select only work you can point to. Uncertainty here is normal and is treated as uncertainty in the result.

    3 — What evidence exists

    Records are what turn a question into a fact. Tell us what you can actually produce on paper.

    Electrical

    Panel labels, ESA/permit paperwork, electrician invoices

    Plumbing

    Supply-line material, repipe invoices, water-service records

    Insulation

    Attic/wall insulation type and date, energy-audit reports

    Roof

    Roofing invoice, warranty, or documented install year

    Heating & fuel

    Furnace/boiler age, fuel type, service records, oil-tank history

    Foundation & structure

    Engineer reports, underpinning or repair records

    Water & moisture

    Past flooding, sump/weeping-tile work, remediation invoices

    Permits

    Municipal permit history for past work

    How this tool decides what to show you

    • Era matching. Each item is tied to a period during which the material or practice was in general Canadian use. Matching the era says the item is worth asking about, nothing more.
    • Evidence adjustment. Telling us records exist, or that a system has been replaced, changes the wording of an item or removes it. Selecting "I don't know" leaves it as an open question.
    • No scoring. There is no risk score, grade, or percentage. Scores imply a precision this method does not have.

    Common questions

    Does this tool tell me what is wrong with my house?
    No. It produces a prioritised list of questions to investigate, based on what was commonly used in Canadian construction during the period your home was built and on what you told us about available records. Nothing here is a diagnosis, an inspection, or a substitute for a qualified professional's assessment.
    Why does my result show items that may not apply to my home?
    Items marked 'commonly associated with this era' reflect general construction practice at the time, not a finding about your specific property. If a system has been replaced or documented, tell the tool and the item is either removed or restated as a question about the scope of that work.
    Do you store my answers?
    No. The tool runs entirely in your browser. Nothing is submitted, saved to an account, or sent to a server. Use the print button to keep a copy.
    What should I do with the results?
    Take the printed list to your home inspector, insurance broker, and any trade you engage, and use it to ask specific questions. Records and professional assessments are what convert a question into a fact.

    Evidence note

    Sources
    Jurisdiction
    Canada, with province-specific requirements noted where they differ. Nothing here should be read as one province's rule applying nationwide.

    Limitations
    This tool applies general era patterns and your own answers. It performs no measurement, inspection, or testing, has no knowledge of your specific property, and cannot detect anything. Construction practice varied by builder, region, and budget; individual homes routinely depart from the pattern for their era.
    What you should verify
    Every item on your list, with a qualified professional and with primary documents — permits, invoices, laboratory results, and written reports.
