Vol. I, MMXXVIThe Canadian home, in season655 stations, every province and territory
An old house is not a money pit just because it is old. It is a known quantity once you know what to look at. Tell us its age, and we will give you a calm watch-list for the things worth checking.
STEP ONE
Use the best year you have. If you only know the era, pick the closest button and start there.
Enter a year or pick an era, and your watch-list appears here.
General awareness only, not legal, safety, or professional advice. For official guidance, check Health Canada, CMHC, your municipality, a licensed inspector, or the licensed trade for the job.
Older homes are made of known patterns. Some are harmless, some need a test, and some need a licensed trade. Once you know which is which, the house feels less mysterious.
Use this as a first question list. Then let inspectors, electricians, plumbers, and qualified remediation pros tell you what is actually in your house.
FULL REFERENCE
This section lists the same watch-list without needing the tool. It is here so you can scan the house by era and bring better questions to an inspection.
ANY OLDER HOME
What it is: Many older basements have no vapor barrier under the concrete slab, so ground moisture wicks up through the floor.
Why it matters: It quietly molds anything sitting on the concrete, even with a dehumidifier running, and cardboard boxes are the first to go.
What to do: Keep everything off the floor on shelving or a pallet, run a dehumidifier, and never store boxes directly on the concrete.
BEFORE 1930
What it is: A framing style in many pre-1930 homes where wall cavities run open from basement to attic.
Why it matters: It lets a fire travel straight up inside the walls.
What to do: Awareness mostly; ask an inspector or contractor about firestopping if you open up walls.
BEFORE 1950
What it is: The original wiring in many pre-1950 homes, with no ground wire.
Why it matters: It can be fine if undisturbed and not overloaded, but insurers often want it assessed or replaced.
What to do: Have a licensed electrician evaluate it, and check what your home insurer requires.
BEFORE 1978
What it is: Homes painted before 1978 may have lead in the old layers.
Why it matters: Dust from sanding or scraping is the real hazard, especially around young kids.
What to do: Do not dry-sand or scrape old paint; get a lead test before any renovation, and use a certified renovator to disturb it.
BEFORE 1980
What it is: Older homes may have galvanized steel, or in some cases lead, supply lines or solder.
Why it matters: Galvanized corrodes and chokes your water pressure over time, and lead is a health concern.
What to do: Get your water tested, and have a licensed plumber identify what your pipes are made of.
What it is: Cast iron drain stacks and clay sewer laterals are common in older homes.
Why it matters: Cast iron corrodes with age, and clay pipe invites tree-root intrusion and blockages.
What to do: A licensed plumber can run a camera down the line to show you its real condition before it surprises you.
BEFORE 1980
What it is: Older homes often have a 60-amp panel or a fuse box.
Why it matters: It may not keep up with modern appliances, and can limit what you add later.
What to do: Have an electrician tell you your service size and whether an upgrade is worth it.
What it is: Homes that once used oil heat may have an old buried or abandoned tank.
Why it matters: A leaking tank is an expensive cleanup and a liability you can inherit.
What to do: Find out from the seller or municipality if a tank exists, and have it assessed or removed by a licensed pro.
BEFORE ABOUT 1990
What it is: Older floor tiles and their glue, pipe and duct wrap, textured or popcorn ceilings, and some attic vermiculite can contain asbestos.
Why it matters: It is only dangerous when disturbed and the fibers go airborne, which is exactly what a renovation does.
What to do: Do not remove it yourself; test before you renovate and hire a licensed asbestos abatement contractor.
No. Age by itself is not the problem. The useful question is what systems and materials belong to that era, and who should check them.
Use the not sure button as a starter list, then ask your municipality, seller, inspector, or records office for a better build year.
No. Treat those as topics where you test first and hire a licensed pro. This page tells you what to ask about, not how to remove or disturb hazards.
No. It is general awareness, not legal, safety, or professional advice. A licensed inspector and the right trades can tell you what is actually in the house.
