Québec’s most established collaborative property database
As Québec’s first platform of its kind, Doormath brings together five years of contributions that enrich comparables and refine each valuation.
Doormath combines five years of community contributions with property registry data and comparables to reveal the true value of properties, whether they’re for sale or not.
Beyond publicly available records
For five years, people who know the properties have enriched Doormath with details public records don’t fully capture: renovations, rooms, and actual condition. This collective knowledge forms a unique property database in Québec. Anyone can enrich a property’s information, and owners can claim their property.

The property, beyond the address
Rooms, light, renovations, and actual condition are part of a property’s story. People who know the property can help tell it.





An address, an area on the map, or a set of characteristics. Choose the starting point that works for you.
Refine the size, rooms, renovations, and actual condition. The details you know enrich the property’s profile.
Compare properties, whether they’re for sale or not, explore neighbourhoods that inspire you, and plan your next move.
Discover a neighbourhood’s homes, including those that aren’t for sale. Explore their values and imagine your next move in a familiar place or somewhere new.



Understand where the value comes from, how to refine it, and what you can do next.
Doormath is Québec’s first collaborative property valuation platform. It combines five years of community contributions with property registry data and comparables to reveal the value of residential properties, whether they’re for sale or not. Owners can claim their property, and users can enrich its information.
Doormath combines the property's exact location and recorded characteristics with automated valuation models and available market data. Details such as size, property type, condition, features and comparable properties can influence the result.
The appraisal is an automated estimate based on the information available at the time. It is a useful starting point, but it is not a certified appraisal, a guaranteed selling price or legal advice. Confirming the property details can make the estimate more representative.
Yes. After opening the property, you can review the recorded characteristics and use the available editing or ownership tools to correct or complete them. Some changes may require you to sign in or verify your connection to the property.
Doormath combines property registry data, comparables, model-generated information, and five years of community contributions. Details supplied or corrected by people who know a property — including renovations, rooms, and actual condition — enrich the database beyond public records. Important facts should be verified before making a decision.
You can search for properties and explore available public appraisals without starting a paid transaction. An account may be required to save information, manage a property, communicate, or use personalized features. Any paid service is identified before purchase.
Property facts and public appraisals may be visible on public property pages. Account details and personal information are handled separately under the Doormath Privacy Policy. Doormath does not sell personal information.
You can review and refine the property details, explore comparable homes, study the surrounding market, review available buyer demand, or speak with a local real estate professional when you are ready.
An owner, a buyer, or simply curious: start with an address. Discover a property’s value and the possibilities of the invisible market.
