What actually drives the price
Four factors decide what a mold job costs
Every mold removal quote comes down to a handful of variables. Size matters most: a small bathroom spot costs far less to fix than mold that’s spread across a basement. Accessibility plays a role too, mold behind a finished wall or inside ductwork takes more labor to reach than mold on an exposed surface. Severity and the containment level required changes the price directly, a Level 1 localized job needs basic containment while a Level 3 structural job needs full containment, HEPA filtration, and airlocks. Finally, material replacement adds cost when drywall, insulation, subflooring, or framing has to come out and be replaced rather than just cleaned. A quote reflects all four of these together, which is why two jobs that sound similar on the phone can price out differently once someone’s actually looked at the space.
10 to 100 sq ft treatment area
Level 2 containment with negative air pressure
Removal of affected drywall, insulation, or framing
Disposal and post-work surface cleaning
100+ sq ft or structural/whole-area scope
Level 3 containment with HEPA filtration and airlocks
Structural material removal and disposal
Coordination with any needed repairs
Once a job moves past a small, localized spot, pricing typically shifts to a per-square-foot basis, roughly $9 to $25 per square foot depending on how accessible the area is and what containment level it needs. A wide-open, easily accessible basement wall sits at the lower end of that range. Mold behind finished walls, inside ductwork, or in a tight crawl space sits at the higher end because of the extra labor and containment required to reach it safely. Because every property and every situation is different, most Ottawa homeowners and property managers get a free on-site estimate rather than relying on a per-square-foot range alone, that’s the only way to get an exact number instead of an estimate range.
Comparing quotes the right way
Why the Lowest Mold Removal Quote Isn't Always the Better Deal
When comparing mold removal quotes, the price alone doesn’t tell you what you’re getting. A lower number can mean a smaller scope of work was quoted, or it can mean containment, proper disposal, or post-work verification were left out entirely. Ask what containment level is included, whether debris is bagged and disposed of properly rather than carried through the house in the open, and whether the price includes a final check of the area once work is done. A written quote that spells out the scope in detail is easier to compare fairly than a number given over the phone with no breakdown behind it.

Describe what you're seeing and where, so we know roughly what to expect before the visit.
2
On-site walkthrough
A technician looks at the affected area, checks accessibility, and takes any needed moisture readings.
3
Scope and containment level set
The visit determines the containment level and whether any material replacement will be needed.
4
Written quote delivered
You get a written price and scope before deciding whether to move forward.
Mold removal cost in Ottawa runs anywhere from a few hundred dollars for a small bathroom spot to well into five figures for whole-house remediation, and the honest answer to "what will this cost me" depends entirely on what's actually there.
Below is a breakdown by job size, plus how inspection and testing pricing compares, so you know what you're looking at before you call.
Mold removal cost questions
What affects the price of mold removal in Ottawa?
Four main things: the size of the affected area, how accessible it is, the containment level the severity requires, and whether materials like drywall or subflooring need to be replaced rather than cleaned.
Does insurance cover mold removal?
It depends on your policy and what caused the moisture. We can provide a written report and photos to support a claim, but coverage decisions belong to your insurer, not us.
Will I get a written quote before work starts?
Yes, always. You'll have a written scope and price in hand before any remediation work begins, no verbal-only estimates.
Does the price change depending on which part of Ottawa I'm in?
No, pricing is driven by the job's scope and containment level, not by neighborhood. We serve Ottawa and the surrounding area at the same rates.
What's typically included in a remediation quote?
Containment setup, removal of affected material, proper disposal, and surface cleaning are standard. Material replacement (drywall, insulation, subflooring) is quoted separately when it's needed.
Is there a minimum charge for a small job?
Small, localized jobs under about 10 square feet typically start around $500, which covers containment, removal, and disposal for a contained spot.
