Ductwork repair costs a normal range of $200 – $2,100, according to Angi and HomeAdvisor, with HomeAdvisor reporting an average of $660.1,2 Angi and HomeAdvisor are corporate siblings, and matching figures between the sibling sites alone don’t establish independent corroboration. Angi puts the average starting cost at $100, and HomeAdvisor notes simple repairs can cost as little as $100 while extensive projects can reach $10,000.1,2 Fixr (updated August 2025) separately reports an average of $600, scoped to repairing a leaky section and applying sealant, within an average range of $200 – $1,000, a $100 low end (damaged vent), and a $6,000 high end (mold removal from a large duct system).3 The publishers’ published estimates differ, so they are presented separately throughout. Prices are national averages*.

What the sources say
| Source | Headline figures | Notes |
|---|---|---|
| Angi (2026 data, updated Oct 2026) | Average starting cost $100; most homeowners pay $200 – $2,100 | Corporate sibling of HomeAdvisor. Angi’s repair-vs-replace section also states “repair costs about $2,100” as a single figure without a stated basis; it is omitted here. Angi’s hole-repair figures conflict internally ($15 – $400 in its table, $150 – $400 in its prose), so Angi’s hole-repair row is not used |
| HomeAdvisor (2026 data, updated Jun 2026) | $660 average; normal range $200 – $2,100; simple repairs from $100; extensive projects to $10,000 | Sibling-published range and tables match Angi’s; the $100 and $10,000 figures sit outside the normal range as HomeAdvisor’s stated extremes |
| Fixr (updated Aug 2025) | $600 average scoped to leak repair plus sealant; average range $200 – $1,000; low $100; high $6,000 | Separately published, pages state no shared sourcing. Fixr’s under-house figures conflict internally ($250 – $900 in its table, $250 – $1,000 in its prose), so Fixr’s under-house row is not used |
Repair cost by problem type
Angi and HomeAdvisor publish an identical repair-type table (matching sibling figures), except that Angi’s hole-repair figures conflict internally; the hole row below is HomeAdvisor’s figure only. Fixr publishes its own table, scoped to ductwork in a standard 1,500 sq.ft. home:1,2,3
| Problem | Angi & HomeAdvisor | Fixr (1,500 sq.ft. home) |
|---|---|---|
| Vent repair | $100 – $300 | $100 – $250 |
| Leak sealing | $375 – $700 | $350 – $650 |
| Hole repair | $150 – $400 (HomeAdvisor) | $150 – $350 |
| Rust or corrosion | $200 – $500 | $150 – $500 |
| Condensation | $200 – $900 | $200 – $1,000 |
| Loose ductwork | $100 – $450 | $100 – $500 |
| Damage or collapse | $150 – $2,000 | $500 – $2,500 |
| Clog removal | $200 – $600 | $200 – $500 |
| Mold remediation | $1,125 – $3,345 | $2,000 – $6,000 |
| Rodent infestation | $175 – $615 | $450 – $2,000 |
No row matches exactly across the two tables, so they are kept in separate columns. Fixr’s infestation figure covers removal plus rodent-proofing; the sibling figure is rodent extermination.1,2,3
Repair cost by duct material
Angi and HomeAdvisor publish an identical material table (matching sibling figures):1,2
| Material | Cost (Angi/HomeAdvisor) |
|---|---|
| Rigid (sheet metal) | $300 – $2,100 |
| Flexible | $100 – $800 |
| Insulated flexible | $200 – $1,200 |
Fixr prices repairs by material for a typical 30-linear-foot section:3
| Material | Cost per 30 lin.ft. section (Fixr) |
|---|---|
| Flexible non-metallic | $200 – $800 |
| Flexible aluminum | $200 – $850 |
| Fiberglass duct board | $250 – $900 |
| Sheet metal | $250 – $1,000 |
The publishers use different material categories and Fixr prices per 30-foot section, so the tables are not directly comparable.1,2,3
Repair cost by duct location
Harder-to-reach ducts cost more to repair because labor is billed by time. Angi and HomeAdvisor publish an identical location table (matching sibling figures); Fixr prices locations per typical 30-foot length:1,2,3
| Location | Angi & HomeAdvisor | Fixr (30 lin.ft. basis) |
|---|---|---|
| Basement | $200 – $3,000 | $200 – $800 |
| Attic | $200 – $1,500 | $200 – $850 |
| Crawl space | $300 – $2,500 | $200 – $900 |
| Under house | $300 – $2,000 | — |
| Walls and floors | $400 – $3,500 | $300 – $1,000 |
| Mobile home | $200 – $1,800 | $150 – $600 |
| General in-home spaces | — | $200 – $1,000 |
Fixr’s under-house figures conflict internally and are omitted. The publishers’ figures also differ in basis – Fixr prices a 30-foot length – so columns are not directly comparable.1,2,3
Labor costs
Angi and HomeAdvisor report HVAC technicians charge $50 – $100 per hour for duct repair (matching sibling figures); HomeAdvisor notes many companies add initial service or diagnostic charges of $75 – $200.1,2 Fixr reports $75 – $200 per hour, with minimum fees around $100 or call-out fees of $75 – $100.3
