This calculator vs. a flat $999 mold special
“$999 mold removal” is not a price for a remediation job — it is a price for one specific 80 sq ft closet, quietly applied to every mold call that comes in.
What a flat $999 mold special is
A flat price is the fastest number a company can put on a postcard, a search ad, or a lead-gen page: one price, no inspection, easy for a homeowner to compare between bids. It works as a lead magnet, and it works for the homeowner as a round number to shop other companies against. Nothing about the number says which containment, which demo, or which extras it was built for.
The number was set for one job — commonly a small, contained area like a closet or bath, roughly 80 sq ft, one containment zone, no demolition, one HEPA and dehumidifier day, no clearance test, no HVAC cleaning, and no dumpster — and then quoted to every caller afterward, whether or not the next job looks anything like the one the special was priced on.
What this calculator does instead
This page keeps no account and sends nothing to a server. You enter affected square footage and containment zones, demolition square footage, HEPA and dehumidifier days, clearance testing, HVAC cleaning, a dumpster, and an occupied home as their own line items, plus your crew's loaded wage, travel and equipment, overhead, and target margin. It turns that into the price, the crew hours, and a walk-away price below which the job loses money — for this job, not the closet the special was built on.
| What a flat $999 special does | What this calculator does instead |
|---|---|
| Charges the same price whether the job is an 80 sq ft closet with one containment zone or an 800 sq ft finished basement with two zones and 240 sq ft of demo. | Prices extra square footage, containment zones, and demo as their own hour and material lines, so a bigger, harder job returns a bigger number instead of the same one. |
| Has no line for a clearance test, HVAC cleaning, a dumpster, or an occupied home — a fully-loaded basement job prices the same as a bare closet. | Adds clearance hours and fee, HVAC hours and cost, dumpster hours and fee, and occupied-home hours only when that scope is turned on, so a loaded job shows up in the price instead of being absorbed into it. |
| Was priced once, on one closet, and never re-derived from affected area, zones, or extras — it is a marketing number, not a cost-basis number. | Recomputes crew hours and materials from the exact area, zones, demo, and extras entered every time, so the price tracks the job rather than a memory of the postcard rate. |
| On this calculator's own 80 sq ft closet preset — the exact job the $999 number is named for — the flat special already sits $207.55 below that job's own walk-away cost, before a dollar of profit. | Returns a walk-away cost of $1,206.55 and a bid price of $1,723.64 for that same closet, at this tool's own shop-rate defaults and a 30% target margin. |
| Gives the crew a number to quote, not a number to check a quote against. | Reports the walk-away cost, the bid price, and the crew hours, so a shopped price can be scored against real cost before the crew commits to it. |
Two jobs, the same containment-blind rate
Using this calculator's own shipped presets, at its own shipped shop rates ($45/hr crew wage, 36% burden, $145 travel and equipment, 18% overhead, a 30% target margin):
| Job | This calculator's price | A flat $999 special | Gap |
|---|---|---|---|
| 80 sq ft closet, 1 zone, 1 equipment day — the job the flat number is named for | $1,723.64 bid price; $1,206.55 break-even cost | $999.00 | The flat special runs $207.55 under this job's own break-even cost, before a dollar of profit, and $724.64 under the calculator's own bid price — even on the exact job it claims to price. |
| 800 sq ft finished basement, 2 zones, 4 dry-out days, 240 sq ft demo, clearance, HVAC, dumpster, occupied | $11,543.43 bid price; $8,080.40 break-even cost | $999.00 | The same $999 special quotes $7,081.40 below this job's own break-even cost, and $10,544.43 below the calculator's bid price. |
Both flat-rate rows use the literal $999 figure named in the calculator's own worked preset, applied to each job as a flat price regardless of containment, demo, or extras. Even the smallest, cheapest job the number is named for already loses money before profit is counted; a bigger remediation turns the same number into a five-figure loss. Run your own job's numbers in the calculator to see where it falls.
A flat special is not wrong because it is simple — it is wrong when it is applied outside the one closet it was built on, and nothing about a postcard rate tells a company or a homeowner when that has happened. This calculator does not replace judgment about your market; it replaces the arithmetic a flat special skips.
Common questions
Why does a flat $999 mold special get a remediation job wrong?
Because the cost driver is containment zones, demo, dry-out days, and extras, not "a mold job" alone. An 80 sq ft closet with one containment zone and one equipment day needs a fraction of the labor and material that an 800 sq ft finished basement needs, with two containment zones, four dry-out days, 240 sq ft of demo, a clearance test, HVAC cleaning, a dumpster, and an occupied home -- none of which scale with a flat marketed price. A $999 special charges both the same.
What job is the $999 number actually built around?
One specific job: a small, contained area like a closet or bath, roughly 80 sq ft, one containment zone, no demolition, one HEPA and dehumidifier day, no clearance test, no HVAC cleaning, and no dumpster. It is a marketing price meant to get the phone to ring, not a number derived from any particular home's containment, demo, or extras.
How big is the pricing gap in practice?
On this calculator's own shipped presets, at its own shipped shop rates ($45/hr crew wage, 36% burden, $145 travel and equipment, 18% overhead, a 30% target margin): even the 80 sq ft closet the $999 number is named for has a walk-away cost of $1,206.55 and a bid price of $1,723.64 -- the flat special already sits $207.55 below that job's own break-even cost, before a dollar of profit, and $724.64 below the calculator's own bid price. Applied to an 800 sq ft finished basement with two containment zones, four dry-out days, 240 sq ft of demo, a clearance test, HVAC cleaning, a dumpster, and an occupied home, the same $999 special is $7,081.40 below that job's own $8,080.40 walk-away cost, and $10,544.43 below the calculator's own bid price.
Is a flat mold special ever the right way to quote?
For a narrow band of jobs close to the one the special was built around -- a small, contained area, one zone, no demo, no clearance test, no HVAC cleaning, no dumpster -- a flat number can land close, though on this calculator's own worked example even that job already runs under cost. The risk is applying it outside that band without noticing, because the postcard price does not know which band a given job is in and neither does the crew until affected area, zones, demo, and extras are actually spelled out.
Does this calculator know what to charge in my market?
No. It has no data on local labor or equipment rates. It takes the affected square footage, containment zones, demo, HEPA and dehumidifier days, clearance testing, HVAC cleaning, a dumpster, occupancy, and your own crew wage, burden, and overhead, and turns that into a price for this job -- the arithmetic a flat special skips, not a market survey.
