WHEN TO TAKE A CLOSER LOOK
What are you noticing?
An odour keeps returning
Explain when and where the odour occurs. An ongoing source needs attention; applying a product alone may not resolve it.
The duct material is unclear
Insulation, lining and system condition affect product suitability. Those details should be checked before an application is agreed.
WHAT TO EXPECT
A clear scope from the first conversation.
Tell us why you are considering it
Explain any odours, water history or specific concern. Persistent moisture or damaged materials may need attention before an application can be considered.
Check the product and duct material
Ask which product is proposed, whether its labelled use suits the intended surface and what instructions apply. Suitability is agreed before work starts.
Keep debris removal in the plan
An application does not replace physical cleaning or removal of accessible dust and debris. Your estimate identifies cleaning and any optional application separately.
Approve the scope first
Discuss application areas, product instructions and any preparation or re-entry requirements with the team. Work proceeds only within the agreed scope.
HOW THE VISIT WORKS
Your cleaning, step by step.
Discuss the concern
We ask what you are trying to address and review the accessible condition instead of treating sanitizing as an automatic requirement.
Confirm cleaning and suitability
Physical debris removal and the duct material are considered before deciding whether a treatment belongs in the scope.
Explain the proposed product
We discuss the product, intended surfaces, label requirements and any preparation or re-entry instructions relevant to the application.
Apply only the agreed treatment
Where suitable and approved, the treatment is carried out according to the product label and agreed scope.
Review the next steps
We explain the completed work and any remaining issue that needs a different remedy or further investigation.

Meet Dial4duct ↗YOUR QUESTIONS, ANSWERED
Common questions about air duct sanitizing.
Is sanitizing always needed after duct cleaning?
No. It is discussed according to the situation, material and product suitability; it is not an automatic requirement.
Will it fix a moisture or mould problem?
An application is not a substitute for identifying and correcting a moisture source or dealing with unsuitable or damaged materials.
Can I see the product information first?
Yes. Ask for the proposed product and label instructions before approving an application. No specific product or result is assumed here.
Do you serve my area in Ontario or Quebec?
Send your city or postal code and property details. Our team confirms coverage, timing and access requirements before booking.
Is sanitizing required after every duct cleaning?
No. It is an optional, suitability-based discussion. A cleaning visit should not automatically imply that a chemical application is needed.
Does sanitizing guarantee that odours or mould will not return?
No. A persistent source or moisture problem needs to be addressed. Sanitizing does not promise sterilization, permanent odour removal or correction of damaged material.
