AfterHow Much Does Duct Repair & Sealing Cost in Gresham?
Duct repair and sealing in Gresham typically runs $350 to $1,850 for most residential jobs. Small repairs like a single disconnected joint or a short run of failed foil tape usually land near the low end, while whole-system sealing with mastic and mesh, or replacing crushed flex runs in a crawlspace, pushes toward the top of that range. Every price we give is an estimate set per job by the written estimate, and the estimate itself is free.
That range is honest for the Gresham market in 2026. The number that actually matters is which problem you have. A pinhole leak in the attic branch is not the same job as re-sealing the trunk line in a 1970s ranch off Hogan Drive, and treating them as the same line item is how homeowners end up surprised. Below, we break out real line-item ranges, explain what moves the price, and tell you where the smarter money goes.
Key Takeaways
- Most duct repair and sealing jobs in Gresham fall between $350 and $1,850.
- Air sealing alone is cheaper than replacing damaged duct sections.
- Crawlspace and attic routing adds labor time, which adds cost.
- Older Gresham housing stock often has failing foil-tape joints that age out fast.

Duct Repair & Sealing Cost Breakdown (2026)
Here’s how the work breaks out by line item in the Gresham area. These are typical ranges, not quotes. Your written estimate is the final word.
| Service | Typical Cost Range | What It Covers |
|---|---|---|
| Air sealing (mastic + mesh at accessible joints) | $350 – $650 | Sealing leaks at registers, plenums, and accessible joints |
| Single duct section repair or reconnection | $250 – $450 | Reconnecting a separated joint, patching a small tear |
| Whole-system sealing (whole house, accessible runs) | $650 – $1,200 | Full mastic seal across trunk and branch runs |
| Flex duct replacement (per run) | $180 – $350 | Swapping crushed or torn flex duct, properly supported |
| Rigid duct repair or section replacement | $400 – $900 | Sheet metal repair, new fittings, sealed seams |
| Crawlspace duct re-routing or re-hang | $500 – $1,500 | Correcting sagging, poorly supported, or obstructed runs |
| Duct inspection with written report | Free with estimate | Camera inspection, leak assessment, photo documentation |
What pushes a job toward the top of that table? Access. A duct leak at a ceiling register in a single-story Gresham home is a straightforward seal. The same leak behind a knee wall in a split-level, or buried under insulation in a cramped crawlspace, costs more because it takes longer. We don’t invent line items to pad the bill, but we do price the actual hours the job takes.
Duct damage in Gresham often traces back to the same failures. Foil tape dries out and peels. Flex duct gets crushed by well-meaning storage or by a plumber who moved it. Rodents get into crawlspaces and open seams. Older forced-air systems in Gresham sometimes have disconnected joints that have been blowing into a crawlspace for years. When we open up the system and find that, the repair is a bigger job than a surface seal, and we tell you before we touch anything.
The equipment matters too. We work with professional-grade cleaning and inspection systems from Rotobrush and Nikro, and we stock and work with six recognized industry brands across the cleaning, filtration, and abatement categories: Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman. That means when we diagnose a problem, we’re not guessing. We can identify the duct type, confirm the failure, and repair it on the spot.
What Affects Duct Repair & Sealing Pricing in Gresham
Six factors drive the number up or down more than anything else:
- Accessibility. Ducts in an open basement are fast to reach. Ducts in a crawlspace or behind finished drywall are not. Gresham has plenty of both, and the labor difference is the largest single variable in the estimate.
- Duct material. Flex duct is cheaper to repair and replace than rigid sheet metal. Rigid duct lasts longer but takes time and skill to seal correctly.
- Number of failed joints. One leak is a small job. Ten leaks scattered across a system is a whole-system seal. We map the system first so you’re not paying for a spot fix that doesn’t hold.
- Exterior leakage into unconditioned space. A duct that leaks into a vented crawlspace or attic is losing conditioned air straight outdoors. That’s the leak worth prioritizing, both for comfort and for energy cost.
- Housing age and layout. Some of Gresham’s older homes have ductwork that predates modern sealing standards. Those systems often need re-supported runs and refitted joints, not just sealant.
- Registers, boots, and plenums. Boot-to-floor connections and plenum seams are common leak points. Repairing them adds time but is often the highest-return fix in the entire system.
One local note that matters: Gresham sits in the Pacific Northwest’s wet winter climate, but the inside of a duct system doesn’t care about rain. What it does care about is the temperature swing between a heated house and a cold crawlspace. That differential is hard on tape and mastic over time. Sealing properly, with mastic and mesh rather than tape, is the fix that lasts through the season.

How to Save on Duct Repair & Sealing
There’s no magic way around a leaking duct, but there are ways to spend the money where it counts.
Get the inspection first. A free estimate with a camera inspection tells you exactly what’s leaking and what it will cost. It costs nothing to know, and it stops you from paying for a full-system seal when only two joints are failing.
Seal the exterior leaks first. Leaks into the attic or crawlspace lose conditioned air straight outdoors. Those are the ones with the fastest payback. Interior leaks matter for comfort, but exterior leaks are where energy dollars go.
Bundle repair with cleaning. If your ducts are due for a cleaning anyway, the inspection will find the leaks at the same visit. One call covers cleaning, repair, and dryer vent safety, so you’re not paying for two separate visits to open the same system.
Don’t tape over a tear and call it done. Consumer foil tape is a temporary fix at best, and it fails fast in a temperature-cycled duct. Mastic and mesh is the standard, and it’s what we use.
Mind the dryer vent separately. Your dryer vent is a fire risk without regular cleaning, and a restricted vent makes the dryer run hotter and longer. Lint buildup in the vent is one of the leading causes of residential dryer fires. It’s a separate service from duct repair, but both fall under the same roof, and checking it while we’re there is often worth the visit.

Repair vs. Replace: Which Makes Sense?
Most duct repairs are worth doing before replacement comes up. Replacement usually makes sense only when the ductwork is crushed or collapsed beyond repair, or when the layout is fundamentally wrong for the house. If the system is mostly sound and leaking at joints, sealing is the smarter spend.
Tell us what you’re seeing. If air is blowing into the crawlspace or the register flow is weak in half the house, that’s a repair question, not a replacement one, and the estimate will tell you which is cheaper for your situation.
FAQs – Duct Repair & Sealing Cost
How much does duct repair and sealing cost in Gresham?
Most residential duct repair and sealing jobs in Gresham cost between $350 and $1,850. A single joint repair or a small sealed section usually runs $250 to $450, while whole-system sealing with mastic typically runs $650 to $1,200. Call (844) 523-1942 for an exact quote, and the estimate is free.
Is it cheaper to repair or replace ductwork?
Repairing is cheaper in almost every case where the duct is still structurally sound. Flex duct replacement runs about $180 to $350 per run, and rigid duct section work runs $400 to $900, but replacing the whole system only makes sense if the ducts are crushed, collapsed, or badly designed. Call (844) 523-1942 and we’ll tell you honestly which way your system leans.
Can you come today?
Same-day service is often available, and we dispatch Sunday through Friday, 7am to 7pm. Call (844) 523-1942. We answer 24/7, and a call outside dispatch hours is booked into the next opening.
Does the duct cleaning cost more if you also find leaks?
No. The cleaning is priced as its own job, and any repair found during the inspection is priced separately in the written estimate, so you see both before you decide. Typical repair line items run $250 to $1,500 depending on what’s found. Call (844) 523-1942 for a free estimate.
What’s the cost difference between sealing and replacing a flex duct run?
Sealing a joint costs less than replacing a run, often around $250 to $450 versus $180 to $350 per flex run replaced. The right call depends on whether the duct is crushed or just leaking, which the inspection settles. Call (844) 523-1942 and we’ll walk you through what we find.
What Happens When You Call
We schedule a visit, bring professional-grade inspection and repair equipment, open up the system, and document what we find with photos.

"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
- Dale Schaefer"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Brooke Norris"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
