This cluster prices mold testing alone -- the diagnosis ticket as the whole purchase, an inspection visit with its sample types on the by-sample-type guide and its ticket read against the remediation ticket 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.
Frame A lines, as reported: the Angi frame
| Frame A line, as printed | 2026 band |

Frame A counts the visit by mold type and by sample, with an air sample reaching $700 for extensive testing and its lab adder lines standing beside the sample rows on the by-sample-type guide.
Frame B lines, as reported: the HomeGuide frame
| Frame B line, as printed | 2026 band |
|---|---|
| Visual inspection and samples | $200-$400 |
| Inspection-and-testing line | $195-$350 |
| Frame A inspection row, apart | $303-$1,075 |
| Frame A lab-sample row, apart | $250-$800 |
Frame B counts one visit in full -- a visual inspection and taking samples on a single line -- and remediation tickets stand only as the other ticket on the testing-vs-remediation guide. 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 neighbours, differentiated
The mold remediation hub prices a scoped remediation job in its own lane, apart from its standalone testing adder lines named apart here. Its testing lines stand inside that hub's own remediation counting. Neither prices a standalone mold test by sample type or lab line.
