12 inspections for every stage of your project
Every property has its own issues. Choose the inspection that fits your situation, or combine several: a pre-purchase inspection with thermography and a well water test, for example.
Pre-purchase inspection
A complete visual examination of the home before you sign at the notary, with a clear photo report telling you what to fix, when, and roughly at what cost.See the service →Pre-sale inspection
Have your property inspected before listing: you'll know its weak points before the buyer does and can fix, disclose or price accordingly.See the service →Condo inspection
An inspection of your private unit plus a read of the syndicate's documents: maintenance log, reserve fund study and minutes, so you know what you're really buying into.See the service →New construction inspection
Pre-acceptance inspection, mid-construction visits and a check before warranty expiry: an independent look at the builder's work while they are still required to fix it.See the service →Multiplex and income property inspection

Risks specific to Québec homes
Some problems are well documented here and cost a lot when discovered after the purchase. A good inspector knows where to look based on the region and construction year.
PyritePyrite-bearing fill lifts basement slabs, mainly in greater Montréal, in buildings from the 1970s to 2000s.PyrrhotiteIt degrades foundation concrete in homes built from 1996 to 2008, mainly in Mauricie and part of Centre-du-Québec.RadonAn invisible natural gas, the leading cause of lung cancer in non-smokers according to Health Canada. Only a test measures it.Sensitive claysLowland marine clays move with moisture and, near slopes, require checking constraint zones.Flood zonesSpring floods and backups leave traces an attentive inspector recognizes in the basement.VermiculiteLoose-fill insulation in old attics that may contain asbestos. We flag it without disturbing it.
RBQ certificate: what changes in 2027
Since October 1, 2024, the Régie du bâtiment du Québec has been issuing a certificate to building inspectors. As of October 1, 2027, this certificate will be mandatory to perform inspections for real-estate transactions in Québec, and inspectors will have to follow the BNQ 3009-500 standard.
For you, it's one more protection: oversight of competencies, uniform practices and reports that are more comparable from one inspector to another. Inspectors in our network already work to this standard, and our reports follow its structure.

How much time should I allow for an inspection?
Count two to three hours for a typical single-family home. A plex, a large house or an older building may take longer.
When will I get my report?
Usually within 24 to 48 hours after the visit, digitally, with annotated photos.
Can the inspector do the repairs?
No. To stay independent, the inspector doesn't do the work they recommend. They point you to the right type of professional.
Do you cover my region?
Yes, we route requests across all 17 administrative regions of Québec. For remote areas, trips are arranged in advance.
How much does an inspection cost?
The price depends on the building type, size and added services. Describe the property in the form: the quote is free and without obligation.
