What drives mitigation cost?
- Rough-in present? — new builds (mandatory since 2015) with a capped pipe are cheapest to finish
- New suction point — coring through an existing slab adds labour
- Crawlspace — membrane + depressurization runs higher ($2,500–$5,500+)
- Multiple suction points — large or split foundations sometimes need two
- Finish work — concealing pipe runs inside finished walls
Testing costs
| Test type | Price (CAD) | Best for |
|---|---|---|
| DIY long-term kit | From $45 | Budget screening (mail to lab) |
| Professional 91-day test | $200 | Gold-standard accuracy |
| Professional short-term (96-hr) | $250 | Faster read (less accurate) |
| Real-estate screening | $399 | Buying/selling timelines |
Honest note: a $45 kit tells you something; a 91-day professional test tells you the truth. Short winter tests read high, short summer tests read low — that's physics, not salesmanship.
