The lines, priced apart by frame
| Cost line | Frame A reading | Frame B reading |
|---|---|---|
| Inspection line (adder) | average $689, commonly $303-$1,075 | no separate line printed |
| Testing line (adder) | $250-$350 basic, $450-$800 comprehensive | no separate line printed |
| Containment line | inside the per-square-foot rows | inside the per-square-foot rows |
| Removal-of-affected-material line | inside the per-square-foot rows | inside the per-square-foot rows |
| Cleaning line | inside the per-square-foot rows | inside the per-square-foot rows |
| Labor line | $75-$120 per hour | inside the $15-$30 band |
| Remediation rows behind the lines | $10-$25 per square foot | $15-$30 per square foot |
Each line prints only where its frame prints it, each apart. The job whole prices on the mold remediation hub.
The containment, removal, and cleaning lines: an absence, named
Neither frame prints the containment line, the removal-of-affected-material line, or the cleaning line as a separate priced line. Those parts of a scoped job ride inside each frame's per-square-foot rows -- Frame A at $10 to $25, Frame B at $15 to $30 -- and inside the totals behind them: Frame A standard projects at $1,223 to $3,757, Frame B at $1,500 to $6,000 on average. The absence is named here rather than filled: a quote pricing one of these lines apart prints its own counting, not a frame row.
The adder lines, priced apart
| Adder line, as published | Frame | 2026 reading |
|---|---|---|
| Post-job clearance testing | neither frame | no separate line printed |
| Rebuild of removed material: damaged-drywall row | Frame A | $1,000-$2,900 |
| Inspection line, pre-job diagnosis | Frame A | average $689 ($303-$1,075) |
| Testing line, pre-job diagnosis | Frame A | $250-$350 / $450-$800 |
Neither frame prints a separate post-job clearance testing line; a clearance row on a quote stands as an adder line apart. The rebuild line is a repair ticket that follows a remediation job -- an adder only, never a remediation row.
The room rows behind the lines, and the neighbours named apart
| Row or total, as published | Frame | 2026 band |
|---|---|---|
| HVAC system remediation | Frame A | $3,000-$10,000 |
| Attic partial / basement partial | Frame B | $1,000-$7,000 / $500-$6,000 |
| Bathroom / crawl space | Frame B | $500-$3,000 / $500-$4,000 |
| Whole house | Frame B | up to $30,000 |
The two frames' per-square-foot bands differ -- Frame A at $10-$25 against Frame B at $15-$30 -- and their rows are built differently: Frame A counts standard projects and room rows, Frame B counts by-size rows and room rows apart. That difference is named as a frame difference on every page here, never averaged. Named apart, never a row here: basement waterproofing, prevention work priced in its own cluster; drywall repair, patch-scale repair on standing walls; duct cleaning, an HVAC cleaning scope priced in its own lane; and standalone mold testing and inspection, diagnosis purchases carried here only as adder lines where a frame prints them, never as this cluster's own rows.

Frequently asked questions
What do the inspection and testing lines print at, as reported?
Frame A prints inspection averaging $689, commonly $303 to $1,075, and testing at $250 to $350 basic and $450 to $800 comprehensive. Frame B prints neither as a separate line. Both are diagnosis lines -- adder lines beside a remediation ticket.
What do the containment, removal, and cleaning lines print at, as reported?
Neither frame prints them as separate priced lines. They ride inside the per-square-foot rows -- Frame A at $10 to $25, Frame B at $15 to $30 -- and inside the totals on the hub.
What does the labor line print at, as reported?
Frame A prints labor at $75 to $120 per hour, beside its $10 to $25 per-square-foot rows. Frame B prints no hourly line; its labor rides inside its $15 to $30 band and its by-size rows, small up to $1,500 and large up to $15,000.
What do the adder lines print at, as reported?
Post-job clearance testing prints as no separate line in either frame -- an adder apart where a quote prints it. Rebuild of removed material prints in Frame A as a damaged-drywall row at $1,000 to $2,900: a repair ticket after the job, never a remediation row.
Can the breakdown lines be added into one total?
No. Totals stand as printed -- Frame A at $1,223 to $3,757 with an average of $2,368, Frame B at $1,500 to $6,000 on average with a whole house up to $30,000. Basement waterproofing, drywall repair, duct cleaning, and standalone testing and inspection are separate purchases, named apart.
