Restoration
Mold Remediation Cost Calculator
Prices mould remediation, where containment and finding the moisture source are the job.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Hours times crew times rate, plus containment materials, equipment and the call-out. Remediation scope follows the affected area and the conditions: setting up containment with sheeting and negative air pressure so spores are not spread through the building, removing affected porous materials, HEPA vacuuming and cleaning the remaining surfaces, running air filtration, and then verifying the result. Area matters, but so does location, because a crawl space or an attic is harder to work in than a wall cavity.
What moves the number
- Affected area and whether it is accessible or in a confined space.
- Containment requirements, which scale with the area and the building's use.
- How much porous material has to be removed rather than cleaned.
- Whether post-remediation verification by a third party is required.
Where this one goes wrong
Remediation without fixing the moisture source is a temporary result, and it is the most common failure in this work: mould grows because something is wet, so unless the leak, the condensation or the humidity is resolved it returns. Finding and reporting the source is part of a competent scope rather than an extra. Containment is the other thing not to economise on, because disturbing growth without it distributes spores through the building and can turn a contained problem into a whole-house one. Note that remediation standards and any licensing requirements vary by state, with several states regulating who may assess and who may remediate.
Before you quote
- Identify and report the moisture source before remediating.
- Set containment and negative pressure before disturbing growth.
- Check state licensing requirements for assessment and remediation.
- Establish whether independent verification is needed before closing.
Where the rules come from
Questions
About this calculator
Will the mould come back after remediation?
If the moisture source is not fixed, yes. Mould grows because something is wet, so a leak, condensation problem or humidity issue has to be resolved or the growth returns. Finding and reporting the source is part of proper remediation rather than a separate job.
Why is containment necessary?
Because disturbing growth releases spores, and without containment and negative air pressure they distribute through the building. That can turn a problem confined to one wall into a building-wide one. The sheeting and air equipment are what keep the work from spreading what it is removing.
Should the same company assess and remediate?
Several states regulate this specifically, with some requiring independence between the party that assesses and the party that remediates, on the obvious reasoning about incentives. It is worth checking the rule where you are rather than assuming one company can do both.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 22 h |
| People needed | 1 |
| Labour rate charged | $135 |
| Parts and materials | $1,300 |
| Call-out or diagnostic fee | $95 |
| Sales tax | 0% |
What comes out
| Result | Value |
|---|---|
| Estimated total main result | $4,365 |
| Labour | $2,970 |
| Before tax | $4,365 |
| Sales tax | $0 |
About $4,365: $2,970 of labour, $1,300 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $68 | $2,891 |
| $101 | $3,617 |
| $135 example above | $4,365 |
| $203 | $5,861 |
| $270 | $7,335 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
