The sample readings, priced apart by frame
| Sample reading | Frame A reading | Frame B reading |
|---|---|---|
| Swab sample | $200-$300 sample row | in $200-$400 visit line |
| Air sample | $250-$350 sample row | in $200-$400 visit line |
| Visit overall | $250-$800 with lab samples | $195-$350 testing line |
Each reading is one frame's own counting of one sample: a sample row counts the named sample alone, a lab row counts the lab line added to a sample, and per-sample rows are never blended into a visit total.
The sample rows, priced apart
| Sample row | Frame A reading | Frame B reading |
|---|---|---|
| Swab / air | $200-$300 / $250-$350 | in visit line / in visit line |
| Air, extensive testing | reaching $700 | in visit line |
| HVAC sample | adding $50-$75 | in visit line |
| Inspection across types | $303-$1,075 | $200-$400 visit line |
Frame A prints its sample rows as their own lines; Frame B prints no per-sample rows, standing in its single visit line, and a row with no printed line in one frame stands as in that frame, never filled from the other frame.
The lab rows, priced apart
| Lab line, as published | Frame | 2026 reading |
|---|---|---|
| Stain lab test | Frame A | adding $150 |
| Culture lab test | Frame A | adding $50 |
| Testing with lab samples | Frame A | $250-$800 |
| Basic / comprehensive | Frame A | $250-$350 / $450-$800 |
The lab lines count the added lab work alone: Frame A prints one adder line per lab type beside its sample rows, never merged into a sample row. The two frames count the same visit differently -- Frame A reads an inspection at $303-$1,075 across mold types with most types at $450-$800, while Frame B reads the visit at $200-$400 for a visual inspection and taking samples. That difference is named as a frame difference on every page here, never averaged.
The totals behind the rows, and the neighbours named apart
Behind the rows stand the headline lines: Frame A inspection at $303-$1,075 with most types at $450-$800, Frame B visit at $200-$400 with its inspection-and-testing line at $195-$350. The diagnosis ticket against the remediation ticket prices apart on the testing-vs-remediation guide. Named apart, never a row here: mold remediation, the remediation cluster's own field and never a diagnosis ticket; whole-home inspection, a whole-inspection ticket and never a standalone test; and DIY test kits, a shelf purchase and never a professional visit.

Frequently asked questions
What does mold testing cost by sample type, as reported?
Frame A prints a swab sample at $200 to $300, an air sample at $250 to $350, and an HVAC sample adding $50 to $75 as sample rows. Frame B counts its samples inside a $200 to $400 visit line. A frame difference, never averaged.
What do the lab rows print at, as reported?
Frame A prints a stain lab test adding $150 and a culture lab test adding $50 as lab adder lines, its testing with lab samples at $250 to $800. Frame B prints no lab rows, apart.
What does the air row print at for extensive testing, as reported?
Frame A counts by sample type, standing apart: an air sample at $250 to $350 reaching $700 for extensive testing, its basic testing at $250 to $350 and comprehensive at $450 to $800 beside it. Frame B stands in its $195 to $350 line, apart.
What does the visit total print at behind the rows, as reported?
Frame A prints an inspection at $303 to $1,075 across mold types, most types at $450 to $800. Frame B prints the visit at $200 to $400 on its inspection-and-samples line, apart in its own frame.
Is a sample row the same purchase as mold remediation or a home inspection?
No. Each row prices one sample or lab line in one diagnosis visit, off a $250 to $800 lab-sample band in Frame A and a $200 to $400 visit line in Frame B. Mold remediation, whole-home inspection, and DIY test kits sit in their own lanes, named apart.
