Restoration
Mold Treatment Cost Calculator
Prices mould treatment, where treatment without removal and a moisture fix does not last.
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 materials and the call-out. Treatment covers the cleaning and application stage: HEPA vacuuming, surface cleaning, applying an antimicrobial where appropriate, and running air filtration. It is one phase of a remediation rather than an alternative to one, and priced alone it looks cheaper than remediation because it excludes the two things that make the result durable, which are removing colonised porous material and resolving the moisture.
What moves the number
- Area and accessibility of the surfaces being treated.
- Whether colonised porous material is being removed as well.
- Whether the moisture source has been identified and resolved.
- Air filtration run time, which continues after the cleaning.
Where this one goes wrong
Antimicrobial application is not a substitute for removal. Treating a surface leaves porous material that is colonised within it, and the growth returns, so a treatment-only scope on drywall or insulation is a temporary cosmetic result. Be plain about that when a customer asks for the cheaper option. The moisture source is the same point: treatment applied to a wall that is still getting wet will fail, and no product changes that. Note also that products claiming to kill mould are regulated as antimicrobial pesticides, so label directions on use, ventilation and application are legal requirements rather than suggestions.
Before you quote
- Say plainly that treatment alone is temporary on porous materials.
- Confirm the moisture source is resolved before treating.
- Follow antimicrobial product label directions, which are legally binding.

Questions
About this calculator
Can mould just be treated rather than removed?
On hard non-porous surfaces, treatment and cleaning works. On porous materials like drywall and insulation the colonisation is inside the material, so treating the surface is cosmetic and the growth returns. Treatment alone on those materials is a temporary result, and it is worth saying so.
Do antimicrobial products solve the problem?
Not on their own. They are part of a cleaning process, not a replacement for removing colonised material and fixing the moisture. They are also regulated as antimicrobial pesticides, so the label directions on application, ventilation and use are legal requirements rather than guidance.
Why is treatment cheaper than remediation?
Because it excludes the two things that make the result last: removing colonised porous material and resolving the moisture source. It is one phase of a remediation rather than a cheaper version of one, and pricing it as an alternative sets up a return visit.
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.
