Every term, one plain-English line, grouped into the home itself, the buying process, and the marketing words a listing uses. Follow a link for the full guide.

The ten second check

What else is typical in a house this age?

Type the year the house was built and I will tell you what else tends to be true at that age, what it costs, and what to ask. One number, ten seconds.

A guess is fine. 1965, or just the 60s.

Anything worrying you? Tap any that apply, or skip it.

Free. No account. Educational and impartial, not a home inspection.

The home: systems, materials and finishes 89

What is behind the walls and under the floors, from wiring and pipes to countertops.

Aerobic treatment unit (ATU)
An advanced septic system that pumps air through the effluent to treat it further before a smaller or more sensitive bed. Carries a mandatory service contract and mechanical parts that wear out. Read the guide →
Aluminum branch wiring
Solid aluminum wiring used for outlets and switches in homes built roughly 1965 to 1973; a recognized fire risk at the connections. Read the guide →
Asbestos-containing materials (ACM)
Heat-resistant materials used until the 1980s-90s (popcorn ceilings, vermiculite, pipe wrap, old floor tile); a hazard only when disturbed. Read the guide →
Backsplash
The tiled or slab surface between the counter and the upper cabinets. Cheap to change, so a dated backsplash is one of the lowest-cost ways to move a kitchen forward. Read the guide →
Baffle
A wall or fitting at a septic tank's inlet and outlet that keeps the settled sludge and floating scum from escaping into the leaching bed. Its condition can only be judged with the tank lid off. Read the guide →
Bathroom exhaust fan (CFM)
The fan that pulls moisture out of a bathroom, rated in CFM. A bathroom with no visible fan, or one that vents into the attic, is a moisture problem dressed as a finish. Read the guide →
Broadloom
Wall-to-wall carpet. It has the shortest life of any floor finish in a home, so its condition tells you more about how long ago the last update was than about the house. Read the guide →
Builder grade
The finish level a developer installs when nobody upgraded: laminate counters, chrome faucets, hollow-core doors, one ceiling light per room. Read the guide →
Butcher block
A solid wood counter. Warm, cheap relative to stone, and the one counter that needs oiling and can be sanded back when it stains. Read the guide →
Cabinet box (carcass)
The structure behind the doors. Plywood boxes hold hardware and survive water. Particleboard or melamine boxes are cheaper and swell if they get wet. This is what refacing keeps and replacing throws away. Read the guide →
Casing
The trim framing a door or window opening. Its width and profile is one of the quietest tells of a home's finish tier, and of which era last touched it. Read the guide →
Caulk
The flexible sealant used where two surfaces meet, such as tile to tub. Caulk belongs in corners; caulk used to fill a gap in the middle of a tile field is a repair covering something up. Read the guide →
Chimney crown
The concrete top of a masonry chimney; when cracked it lets water in, which freezes and crumbles the mortar over time. Read the guide →
Cosmetic (appearance) score
Casaroo's score for how updated and enjoyable a home is, kitchen, baths, finishes, read alongside the mechanical (bones) score.
Cultured marble
The moulded one-piece bowl-and-counter vanity top common in 1980s and 1990s homes; it has a life of about 20 years. Read the guide →
Cupping
Floorboards whose edges sit higher than their centres; a moisture symptom, not a flooring defect. Read the guide →
Curbless (walk-in) shower
A shower with no lip to step over. It requires the floor to be lowered or built up so it can drain, so it is almost never a cosmetic change. Read the guide →
Drain, waste & vent (DWV)
The plumbing that carries water out of a house; in pre-1975 homes it is often cast iron, which corrodes from the inside and is best checked with a camera scope. Read the guide →
Drop-in (top-mount) sink
A sink with a rim that sits on top of the counter. Cheaper to install than an undermount, and a reliable tell that the counter is laminate, because undermounts need a solid edge. Read the guide →
Efflorescence
White mineral powder left on basement walls by water passing through them; a sign of moisture intrusion, often from poor grading. Read the guide →
Effluent
The clarified liquid in the middle of a septic tank, between the sludge that settles and the scum that floats. It is the only part meant to flow on to the leaching bed. Read the guide →
Electrical service (amperage)
How much power a home can draw, 60, 100, or 200 amps; 60-amp service is often undersized and uninsurable for a modern home. Read the guide →
Engineered hardwood
A real wood veneer over plywood layers. Stabler than solid wood, so it suits basements and concrete, and it can be refinished only as many times as the veneer allows. Read the guide →
Era tell
A finish that dates a home almost exactly: an oak strip floor, a pink tub, a cultured-marble vanity, an over-the-range microwave. Reading them tells you when the home was last touched, and therefore what is due. Read the guide →
Exhaust venting into the attic
When bath or kitchen fans dump moist air into the attic instead of outside, trapping humidity that causes hidden mould and rot. Read the guide →
Federal Pacific (FPE) Stab-Lok panel
An electrical panel sold from the 1950s-80s whose breakers can fail to trip; flagged for replacement regardless of condition. Read the guide →
Finished basement (below grade)
Living space built below ground level. The finish quality matters less than what is behind it: whether it was permitted, whether the bedroom window meets egress, and whether the space has ever been wet. Read the guide →
Fit and finish
The small stuff: doors, trim, hardware and lighting. Renovators touch it last and skip it first, which is exactly why it is the most reliable place to see where a budget really went. Read the guide →
Fixture finish
Chrome, brushed nickel, matte black, brass. Purely a style choice, dated fast, and cheap to change, so never let a fixture finish move your read of a home's quality. Read the guide →
Flip
A home bought, cosmetically renovated, and resold; not inherently a problem, but the incentives favour spending on what a photo shows. Read the guide →
Flue liner
The lining inside a chimney that safely carries combustion gases out of the house; damage is a carbon-monoxide and fire risk. Read the guide →
Foundation movement
Active shifting of a foundation, signalled by horizontal, bowing, or stair-step cracks (unlike ordinary vertical hairline cracks). Read the guide →
Frameless glass
A shower enclosure of thick glass with no metal frame. A premium tell, and a real cost: the glass is heavy, the hardware is precise, and the walls must be plumb. Read the guide →
Galvanized steel pipe
Zinc-coated steel water pipe (pre-1960) that corrodes and scales up inside, causing low pressure and rusty water; magnetic, unlike lead. Read the guide →
GFCI
A ground-fault outlet with test/reset buttons that cuts power instantly if electricity tries to travel through water; required near sinks, baths, and outdoors. Read the guide →
Grout
The hard cement filler between tiles. It is porous, it stains, and it cracks when the substrate moves. Cracked grout in a shower is a water question, not a cleaning one. Read the guide →
Gut renovation
A renovation taken back to the studs, usually because fixtures move. Moving plumbing and electrical is the line where a refresh becomes a gut, and where the price roughly triples. Read the guide →
Heat exchanger
The furnace component that separates combustion gases from your home's air; a crack in it is a carbon-monoxide risk and usually means the furnace needs replacing. Read the guide →
Holding tank
A sealed septic tank with no leaching bed (Ontario Class 5) that stores all sewage until a truck empties it, often every four to eight weeks. The most expensive system type to live with. Read the guide →
Hollow-core door
An interior door with a cardboard honeycomb between two thin skins; standard in tract housing and a reliable tell about a renovation's budget. Read the guide →
Ice dam
A ridge of ice at cold roof eaves caused by heat escaping a poorly insulated attic; it backs water under the shingles and into the house. Read the guide →
Knob-and-tube wiring (K&T)
The original pre-1950 wiring method using ceramic knobs and tubes with no ground wire; an insurance and safety concern in older homes. Read the guide →
Knockdown / stipple texture
A sprayed and flattened wall or ceiling texture. On a pre-1990 ceiling, treat any sprayed texture as a possible asbestos question and test before you sand it. Read the guide →
Laminate counter
A photographic layer over particleboard. The single most reliable value tell in a listing photo, and a straightforward thing to price into your offer. Read the guide →
Leaching bed (drain field / weeping bed)
The buried network of pipes and gravel, or an engineered sand filter, where the soil finishes treating septic effluent. The expensive half of a septic system to replace. Read the guide →
Lead paint
Paint containing lead, mainly in pre-1980 homes; the hazard is lead dust from sanding or peeling, most harmful to young children and pregnant women. Read the guide →
Lead service line
The pipe carrying city water into a pre-1960s home that may be made of lead, a health concern; dull grey, soft, and non-magnetic. Read the guide →
Luxury vinyl plank (LVP)
An all-plastic plank floor that resists water, unlike laminate, whose wood-based core swells when it gets wet. Read the guide →
Mechanical (bones) score
Casaroo's score for how sound a home is and what it will cost, roof, heating, electrical, plumbing, structure, read alongside the home's appearance.
Millwork
Custom-built trim, panelling and joinery; a 100-plus year item and one of the strongest genuine markers of a premium home. Read the guide →
Mould
Fungal growth that appears where moisture lingers; a symptom of a water source, a leak, poor grading, or weak ventilation, that needs fixing, not just cleaning. Read the guide →
Negative grading
Ground that slopes toward a house instead of away from it; the most common, most preventable cause of wet basements and foundation trouble. Read the guide →
Over-the-range microwave
A microwave mounted above the stove doing double duty as the range hood. Common, and a builder-grade tell: it vents weakly and it puts the microwave at face height over a hot pan. Read the guide →
Panel-ready (integrated) appliance
A fridge or dishwasher built to accept a cabinet door front, so it disappears into the run. A genuine premium tell, and expensive to add later. Read the guide →
Polybutylene (poly-B)
Grey flexible plastic supply pipe installed from the late 1970s to mid-1990s that can fail without warning; an insurance flag. Read the guide →
Popcorn ceiling
The sprayed textured ceiling common from the 1950s to the 1980s; on a pre-1990 home it should be treated as containing asbestos until tested. Read the guide →
Porcelain vs ceramic
Both are fired clay tile. Porcelain is denser, harder and absorbs almost no water, so it costs more and belongs anywhere that gets wet or sees traffic. Read the guide →
Pot light
A recessed ceiling light; running roughly $150 to $300 each installed, it is the most common lighting upgrade in a dated home. Read the guide →
Powder room (two-piece)
A bathroom with a toilet and a sink, no tub or shower. The smallest real bathroom job, and even it starts around $8,500 in the GTA. Read the guide →
Quarter round
The small curved trim at the base of a baseboard, used to hide the gap when new flooring is laid without removing the baseboards. Its presence is a shortcut tell. Read the guide →
Quartz (engineered stone)
Ground stone bound with resin, sold in slabs. Non-porous, no sealing, and the default mid to upper counter in most 2026 renovations. Not the same thing as quartzite. Read the guide →
Quartzite
A natural stone quarried in slabs, often confused with quartz because of the name. It is stone, so it needs sealing, and it usually costs more. Read the guide →
Radon
A colourless, odourless radioactive soil gas that collects in basements; Canada's leading cause of lung cancer after smoking, with an action guideline of 200 Bq/m³. Read the guide →
Refacing
Replacing cabinet doors and fronts while keeping the existing boxes; most of the look of a new kitchen at a fraction of the cost. Read the guide →
Refresh (renovation tier)
A renovation that changes surfaces and leaves the layout alone: paint, hardware, counters, backsplash. Nothing moves, so no permit and no plumber. It is the cheapest tier and the one buyers most often underestimate. Read the guide →
Roof end of life
Asphalt shingle roofs last about 20 to 30 years; curling shingles, granule loss, moss, and multiple layers signal a roof near replacement. Read the guide →
Sand and refinish
Sanding a hardwood floor back and applying new finish, rather than replacing it. It costs roughly a third of new flooring, and it is the single most overlooked option in a listing with tired wood floors. Read the guide →
Septic dye test
A basic septic check where coloured dye is added and water is run to see if effluent surfaces in the yard. Cheaper and less thorough than a full inspection with the tank opened and pumped. Read the guide →
Shaker
A flat centre panel with a square frame. The most common cabinet door style of the last fifteen years, sold at every price point, so shaker alone tells you nothing about quality. Read the guide →
Sheen (eggshell, satin, semi-gloss)
How much light a paint reflects. Higher sheen wipes clean and shows every wall flaw; flatter sheen hides flaws and marks easily. It is why a bad wall often hides under flat paint. Read the guide →
Sheet vinyl
Flooring that comes in a continuous roll rather than planks or tiles. Inexpensive and water-resistant, and in a 2026 listing it usually means the floor has not been touched in decades. Read the guide →
Subfloor
The structural sheet under your finished floor. It is what makes a floor feel solid or bouncy, and levelling it is the cost that quietly appears in every flooring quote. Read the guide →
Thermofoil
A vinyl skin heat-wrapped over MDF cabinet doors. It looks painted until it peels, usually beside the oven or dishwasher where the heat is. Read the guide →
Three-piece / four-piece bath
The fixture count: three is toilet, sink and tub or shower; four adds a separate tub and shower. It is the fastest way to read how much plumbing a bathroom actually contains. Read the guide →
Transition strip
The trim that bridges two different floors in a doorway. Missing or mismatched transitions are the clearest sign flooring was done room by room rather than in one go. Read the guide →
Treads and risers
The horizontal and vertical parts of a stair. Refinishing or recapping them is cosmetic; the guard height and handrail beside them are a safety matter and belong on the Bones side. Read the guide →
Tub surround
The waterproof wall around a tub, in tile, acrylic or fibreglass. Staining or softness at its base is a moisture finding, and it belongs on the Bones side of the report. Read the guide →
Underground storage tank (UST)
A buried heating-oil tank; corrosion and leaks can cause costly soil contamination and make a home hard to insure. Read the guide →
Underlayment
The thin layer between subfloor and finished floor: foam, cork, or membrane. It handles sound, small imperfections and moisture, and it is where a cheap install cuts corners. Read the guide →
Undermount sink
A sink fixed beneath the counter with no rim, so you can wipe straight into it. It requires a stone or solid-surface counter, which is why it reads as an upgrade. Read the guide →
Ungrounded (two-prong) outlet
An outlet with no safety ground path; common in older homes and sometimes a clue to bigger wiring problems. Read the guide →
Vanity
The bathroom cabinet and its counter. A dated vanity with an integrated cultured-marble top is one of the clearest 1990s tells there is. Read the guide →
Vermiculite insulation (Zonolite)
Pebble-like loose-fill attic insulation that may contain asbestos; Health Canada advises assuming it does and not disturbing it. Read the guide →
Virtual staging
Furniture added to a photo digitally. It is legitimate and normally disclosed, but it makes finishes and light unreliable, so never read a finish tier from a virtually staged room. Read the guide →
Water heater end of life
A tank water heater lasts about 8 to 12 years; the manufacture date is printed on the label and most buyers never check it. Read the guide →
Waterfall edge
A stone countertop that turns and runs down the side of an island; the veining must match across the corner, which is why it signals slab stone. Read the guide →
Wear layer
The thin skin of real wood on top of an engineered hardwood plank; it decides whether the floor can ever be refinished. Read the guide →
Work triangle
The path between sink, stove and fridge. It is the reason a layout either works or fights you, and changing it means moving plumbing and gas, which is the line where a refresh becomes a renovation. Read the guide →
Zinsco panel
A failure-prone electrical panel (also branded GTE-Sylvania) with colourful breaker handles; flagged for replacement. Read the guide →

Buying, offers and closing 34

The words in your offer and on closing day, from deposit to title.

Adjustments
The final tidying up of shared costs on closing day, so that things the seller prepaid or left unpaid, like property tax or fuel in an oil tank, land on the right person.
Agreement of purchase and sale
The contract that sets out the price, the conditions, the closing date and what is included. In Ontario this is the document everyone means by the offer.
Appraisal
A lender's assessment of what the property is worth. If it comes in below the price you agreed, the lender may lend less and you cover the gap.
Assignment
Selling your rights under a purchase contract to someone else before closing, most often on a pre-construction home. Often restricted by the contract.
Bully offer
A pre-emptive offer made before the seller's scheduled offer date, usually well above asking and with few or no conditions, intended to end the process early.
Chattels and fixtures
Chattels are movable items, like a fridge. Fixtures are attached to the home, like a light fitting. What stays and what goes is decided by the contract, not by assumption.
Closing costs
The costs beyond the purchase price that fall due around closing, including land transfer tax, legal fees, title insurance, adjustments and an inspection.
Closing date
The day title transfers, the money moves and the home becomes yours.
Condition precedent
A requirement written into the offer that must be satisfied before the deal becomes firm, such as arranging financing or reviewing a document.
Conditional offer
An offer that only becomes binding once stated conditions are met or waived by their deadlines. Until then you generally have a way out.
Deposit
The money you hand over shortly after your offer is accepted, usually within 24 hours, to show the seller you are serious. It is held in the listing brokerage's trust account and counts toward your down payment at closing.
Down payment
The share of the purchase price you pay yourself rather than borrow. Your deposit forms part of it, so you owe the remainder at closing, not the full amount again.
Escalation clause
A term that automatically raises your offer above competing offers up to a stated ceiling. Not used everywhere and not always permitted.
Financing condition
Time written into the offer to get final mortgage approval on that specific property. Pre-approval is not the same thing, because the lender still has to approve the home.
Firm offer
An offer with no remaining conditions. Once an offer is firm you are committed to completing the purchase.
Holdback
An amount kept back from the seller's proceeds at closing until something specific is completed or resolved.
Inspection condition
Time written into the offer to have the home inspected and to decide what to do about what is found. Typically several business days.
Irrevocable date
The deadline after which the offer expires if the other side has not accepted it.
Land transfer tax
A tax on the transfer of property, payable at closing. Rates vary by province, Toronto charges its own on top, and first-time buyers may qualify for a rebate.
Latent defect
A problem that is not visible on an ordinary viewing. Rules on what a seller must disclose vary by province and turn on what the seller knew and whether the defect makes the home dangerous or unfit to live in. If a latent defect is in question, that is a conversation for a lawyer.
Mortgage pre-approval
A lender's early indication of how much you could borrow, based on you rather than on a specific home. It is not final approval.
Notice of fulfilment
A signed document confirming a condition has been satisfied rather than given up. Similar effect to a waiver, different meaning.
Occupancy
On a new build, the period when you can move in and pay occupancy fees before final closing and before you legally own the unit.
Patent defect
A problem a reasonable buyer could see on an ordinary viewing, such as a visibly sagging floor. Generally the buyer's risk to notice.
Possession
The moment you actually get the keys and can enter the home, which is usually but not always the same day as closing.
Repair credit
Money the seller agrees to leave with you at closing instead of doing a repair, so you can arrange the work yourself.
Repair exposure
The rough total cost of the mechanical repairs a home is likely to need. Casaroo uses this to describe what the bones may cost you, separate from anything cosmetic.
Reserve fund
The condo corporation's savings for major repairs like roofs, elevators and garage membranes. A thin reserve is what makes a special assessment likely.
Seller property information statement
An optional form on which a seller answers questions about the property. It is voluntary in most places, and an unanswered form is not an answer.
Special assessment
A one-time charge levied on condo owners when the reserve fund cannot cover a major repair. It can arrive without much warning and can be large.
Status certificate
The condo corporation's disclosure package for a specific unit, covering fees, the reserve fund, budgets, planned increases, special assessments, lawsuits and insurance.
Title
The legal ownership of the property. Your lawyer searches it before closing to confirm the seller can sell and that nothing unexpected is registered against it.
Title insurance
A one-time policy that protects against certain title problems discovered later, such as survey issues, unpermitted work registered against title, or fraud.
Waiver
A signed document giving up a condition you were entitled to rely on. Signing one moves the deal closer to firm.

Listing language decoder 6

What the marketing phrases in a listing are really telling you.

“As-is” / “blank canvas” / “handyman special”
The seller is telling you, in the politest language available, that they will not be repairing anything and that the condition is likely worse than the photos flatter. Believe them, and price it. Read the guide →
“Chef’s kitchen”
Marketing language with no definition behind it. Look for what would actually earn it: integrated or professional appliances, a real hood vented outside, and stone counters. If the photos do not show them, treat the claim as words. Read the guide →
“Designer finishes”
A claim about taste, not quality. It is perfectly compatible with builder-grade cabinet boxes and hollow-core doors, so read the finish tier from the photos instead. Read the guide →
“Move-in ready”
It means nothing is stopping you moving in, which is a low bar and says nothing about the mechanicals. A home can be move-in ready and still need a roof. Read the guide →
“Spa-like ensuite”
Marketing language. What would earn it is frameless glass, a properly vented fan, a heated floor, and stone. What often sits behind it is a builder bathroom with a rain head. Read the guide →
“Tastefully updated” / “newly renovated”
New finishes were installed recently. It says nothing about who installed them, whether permits were pulled, or whether anything behind the walls was touched. Always ask about permits. Read the guide →
