The finished basement in Châteauguay
- 66.8% of houses sold in Châteauguay in 2026 have a fully finished basement, against 4.6% with an unfinished basement (the rest: partly finished, crawl space or field left blank). Median of the 52 cities: 67% fully finished.
- Finished versus unfinished: median gap of +21% over 11 years in which both groups have at least 10 sales (2023: +16%, 2024: +16%, 2025: +20%, 2026: +23%).
- Against all houses, the fully finished basement premium is +4% at the median over 11 years (+5% in 2026).
The fireplace or stove in Châteauguay
- 33.0% of houses sold in Châteauguay in 2026 have at least one fireplace or stove (wood, gas, pellets or oil), against 43.3% in 2016.
- Median premium over 11 years: +2%; in 2026: +3% (rank 42 of 52 cities).
Forced air and heat pumps in Châteauguay
- 40.2% of houses sold in Châteauguay in 2026 are heated by forced air (ducts), against 45.2% in 2016; median of the 52 cities: 31%. Other heating modes listed: electric baseboards, hot water, convection baseboards, radiant.
- Median premium over 11 years: -2%; in 2026: -2% (rank 44 of 52).
- Why forced air and not "heat pump"? Centris has no search field for heat pumps. Forced-air ducts are what allow a central heat pump (heating and cooling in the whole house); with baseboards, wall-mounted heat pumps are the usual choice. Heat pump grants apply in both cases.
What it means for selling or buying in Châteauguay
These gaps compare GROUPS of houses, not the effect of a renovation. A house with a fireplace or forced air may also be larger or from another era. For a seller in Châteauguay, finishing the basement before selling makes the most sense where almost every house sold already has one: buyers compare to that. Do it with a permit, and only present a room as a bedroom if it has a compliant egress window. For a buyer, an unfinished basement is room to negotiate, not a flaw, if the foundation is sound and dry. A broker on the team can compare your house with sales in Châteauguay that have the same features.
How to read these figures
Figures for all single-family houses sold on Centris in Châteauguay: median sale price (half of sales above, half below) and number of sales per year. "Fully finished" and "unfinished" are values of the listing's "Basement" field; "fireplace or stove" = at least one of the 8 types in the "Fireplace-Stove" field; "forced air" = heating mode "Forced air". A blank field is not counted, so fireplace and forced air are compared with all houses, which include them. Fewer than 10 sales in a year: median left blank (n/a). 2026 runs from January to September.
