The EPA's ten square feet is a sales tool, not just a guideline
Every mold firm complains about price shoppers. The fix is not better closing — it is putting a measurable, third-party threshold between the phone call and the quote. The EPA already published one.
What the threshold actually says
The EPA's mould guidance draws a line at roughly ten square feet of contiguous growth. Below it, a homeowner can clean non-porous surfaces themselves with detergent and water, wearing an N-95, goggles and gloves, provided the moisture source is fixed. No containment required.
Above it, the guidance moves to containment, HEPA filtration and negative air pressure — because disturbing that much growth puts enough spores in the air that engineering controls are the only way to keep the contamination in one room.
The EPA also flags two situations where size stops being the deciding factor: growth inside HVAC systems, and contamination following sewage or storm water.
Why this is a qualification line and not trivia
The reason mould leads arrive as price shoppers is that nothing in the conversation establishes scope before someone asks for a number. The homeowner has a photo and a fear. You have a truck and a price list. The comparison defaults to price because price is the only comparable thing on the table.
A published third-party threshold changes the shape of that conversation. You are no longer arguing that your remediation is better than the cheap crew's — you are asking a factual question that has to be answered before anyone can price anything: how many square feet, and is the HVAC involved?
Most homeowners cannot answer it. That is the point. The next step becomes an inspection, not a quote.
How to build the intake around it
Three changes, in order of impact:
- Ask for area at intake. A single question — roughly how large is the visible growth, in square feet — with the EPA line stated next to it. Under ten, route to information and a paid inspection option. Over ten, or HVAC involved, or sewage: that is a remediation conversation and it should be prioritised.
- Sell the inspection, not the estimate. A paid inspection with testing filters out renters, tyre-kickers and people harvesting your scope for a cheaper crew. Volume drops. Close rate rises. Those two facts are the same fact.
- Report findings in writing. Area measured, moisture readings, whether the EPA threshold is exceeded, and what the standard calls for at that scale. The homeowner now has a document. The cheap competitor has a verbal number.
What to measure afterwards
If you make this change, stop measuring leads. Measure these three, and measure them before the change so you have a baseline:
- Inspection-to-remediation conversion. The single number that tells you whether the wedge is working.
- Estimator hours per signed job. The cost the free estimate was hiding.
- Share of leads that are owner-occupiers. Renters cannot authorise work, and they are a large slice of unfiltered mould volume.
We are not going to tell you what those numbers should be, because any figure we published would be a guess about your market. Measure your own for one month, then change one thing.
