to be confirmed
“Published by the contractor” is data the contractor publishes in their profile. “Established by Nordis” is a selection reason calculated by Nordis. A field the real file does not contain shows as “to be confirmed”.
This preview is a sample built to explain the project file. In your file, the work prices, fees, inclusions and exclusions shown are the ones each contractor published in advance, for the options eligible to your project, and only where they published them.
If no contractor is eligible in your area when you submit, the file says so plainly and the Nordis team helps you with the next step.
Health Canada distinguishes testing for radon from work to reduce its concentration. Start by specifying your stage and request an offer that matches it.
Initial test
Ask about the method, proposed location, testing duration and whether analysis and a report are included.
Interpreting a result
Prepare the complete report, dates and testing conditions. Clarify what assessment of the result includes.
Mitigation work
Ask about the proposed solution, building work, power supply and included finishes. The layout needs an on-site assessment.
Post-work checks
Clarify follow-up testing, the report provided, system maintenance and any offered warranty terms.
These points help you read offers. The company must confirm the work price and scope before you agree.
Testing and mitigation are not the same intervention
The flow asks why you are starting, where testing stands and what type of property is involved. It avoids presenting a threshold or result as a conclusion without source and context.
01
Your current stage
Never tested, elevated result or mitigation pending: each situation calls for a different next step.
02
Building type
A house, semi-detached home and condo are not planned the same way.
03
Qualified professional
Testing and mitigation may involve distinct skills or certifications.

Radon levels vary from property to property. The only way to know a home’s situation is to follow a recognized testing method and interpret the result correctly.
Can I test radon myself?
Yes, residential methods exist. You must follow the duration, placement and instructions of the method used; a professional can help choose an approach.
Does an elevated result mean I should panic?
No. A result first calls for interpretation and, if needed, confirmation or mitigation. Do not make a decision based on an isolated number.
What happens after my request?
Your file shows the options genuinely eligible for your project, with what each contractor actually published. You then request the visit or book the slot that suits you, in the calendar of the contractor you choose. When no slot is published, the Nordis team helps you with the next step. If no option is available in your area, the file says so plainly: neither a response nor a date is promised.
