AfterHow Much Does Duct Repair & Sealing Cost in Spokane?
Duct repair and sealing in Spokane typically costs $350 to $1,200 for most homes, with small single-run repairs at the low end and full-house sealing with duct replacement at the top. Sealing alone usually runs $350 to $800, while repairing crushed or disconnected runs pushes the job toward $600 to $1,500. The written estimate sets the final price, and the estimate itself is free.
Those ranges come from the work itself: how much duct you can reach, how much of it is actually damaged, and whether the system is leaking at seams or torn apart at a joint. We work on ductwork exclusively, using professional-grade Rotobrush and Nikro equipment, so the diagnosis and the repair happen on the same visit instead of getting handed to a second contractor.

Key Takeaways
- Most Spokane duct repair and sealing jobs land between $350 and $1,200.
- Sealing alone: roughly $350 to $800. Repairs with sealing: $600 to $1,500.
- Attic and crawlspace duct runs cost more because access is slower and the work is harder.
- Cleaning plus repair on the same visit is usually cheaper than two separate appointments.
- The written estimate sets the price. Every estimate is free.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s how the line items break down for a typical Spokane home. These are estimated ranges for the Spokane market, not a quote for your house.
| Service | Typical Range | What It Covers |
|---|---|---|
| Sealing accessible joints and seams | $350 – $800 | Mastic and tape on reachable joints, plenum connections, and register boots |
| Single disconnected or crushed flex run | $250 – $550 | Replacing one flexible duct run and reconnecting it at the boot and plenum |
| Multiple run repairs | $600 – $1,500 | Several damaged runs, often in the attic or crawlspace, with sealing included |
| Rigid duct section replacement | $400 – $900 | Cutting out and rebuilding a damaged section of sheet metal trunk line |
| Duct repair combined with air duct cleaning | $700 – $1,600 | Full cleaning before repair so debris doesn’t get pushed into the new connections |
| Register boot and plenum reconnection | $200 – $450 each | Reseating a boot that has separated from the floor or wall |
What pushes a job up? Distance from the plenum, how many runs are damaged, and whether the ductwork sits in an attic that hits 130 degrees in July or a crawlspace you have to crawl through on your stomach. What keeps it down? Easy access and damage that’s concentrated in one area. A job that needs one run reconnected and a handful of joints sealed is a very different ticket than a house with a dozen separated boots and a collapsed trunk line.
We use Abatement Technologies equipment when a job calls for containment, which matters in homes where the ductwork has held debris for years and the repair will disturb it. Cleaning first, then repairing, keeps the new connections clean.
What Affects Duct Repair & Sealing Pricing in Spokane
- Attic versus crawlspace access. Most Spokane homes run ductwork through the attic or a crawlspace. Attic work in summer means early-morning starts because the space gets dangerously hot by mid-day. Crawlspace work is slower because there’s less room to move. Both add labor time compared with a basement run you can walk up to.
- How many runs are damaged. One crushed flex run is a small job. Six separated boots across three rooms is a different day’s work. The count matters more than the square footage of the house.
- Flex duct versus rigid sheet metal. Flexible duct is faster to replace. Rigid metal trunk lines take cutting, fitting and sealing, and the labor reflects that.
- Whether cleaning is included. If the ductwork hasn’t been cleaned in years, repairing it first means the new connections get coated in the same debris. Cleaning before repair costs less than doing them separately, and it’s the right order of operations.
- Concealed ductwork. Duct runs behind finished walls or under flooring with no access panel need openings cut, which adds time and patching.
- Dry climate and seasonal movement. Spokane’s dry summers and cold winters work the joints in a duct system. Tape dries out and lifts, mastic cracks, and flex runs pulling against their connections separate over time. A system that was sealed years ago can need resealing without anything being “broken.”
Why Duct Repair and Sealing Matters More Than Most Homeowners Expect
A leaking duct system does two things at once: it loses conditioned air before it reaches the room, and it pulls air from wherever the ductwork runs. In a Spokane attic or crawlspace, that means the system can be drawing in insulation fibers, dust, and outside air through every gap. Sealing and repairing those gaps is one of the few home improvements where the fix is physical and verifiable: you can see the mastic, you can feel the airflow change at the register.
This is also why we treat duct cleaning in Spokane and duct repair as two halves of the same job. A cleaning crew that only cleans and leaves a disconnected run behind has done half the work. Our technicians have up to 13 years of experience, every one of them working in air duct and dryer vent services exclusively, so a damaged run gets diagnosed and repaired rather than noted on a clipboard and forgotten.
We also work with Honeywell and Aprilaire filtration and air quality systems, which matters when a repair changes how the system moves air. A filter that was sized for a leaking system can behave differently once the leaks are sealed and the static pressure shifts. Understanding the whole air path, not just the inside of a duct, is part of getting the repair right.
Can You Repair Ductwork the Same Day?
Yes, in most cases. Single-run repairs and joint sealing are usually completed in one visit, often in two to four hours. Larger jobs involving multiple runs or rigid duct replacement may need a second visit if parts have to be matched to your system. Call (866) 963-7098 in the morning and we can usually get a technician out the same day. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
How to Save on Duct Repair & Sealing
The biggest savings come from doing the diagnosis properly the first time. A repair that fails because the wrong joint was sealed costs more than the original job. Beyond that:
- Bundle cleaning and repair. Doing both on one visit avoids a second trip and means the repair isn’t sitting on top of years of debris. It’s also the correct sequence.
- Fix it before it spreads. A small separation at a boot gets worse as the system cycles. Addressing one run now is cheaper than addressing four later.
- Get the estimate in writing before work starts. Any quote that changes on the day needs a reason you can see. Ours doesn’t: the written estimate sets the final price.
- Ask what’s actually being sealed. Accessible joints only, or the whole system? The scope should be spelled out, because “seal the ducts” means different things to different companies.
- Don’t skip the dryer vent. It’s a separate system, but a blocked dryer vent is a fire risk, and generalist companies often skip it entirely. We handle it as its own dedicated service.
Estimates are free, and there’s no service-call fee to get one. Call (866) 963-7098 and we’ll walk through what your system needs.
Repair or Replace the Ductwork?
Repair is almost always the right call when the ductwork is intact except for specific failures: a disconnected run, a crushed section, lifted tape, cracked mastic. Replacement starts making sense when the ductwork is sized wrong for the system, when the trunk line has collapsed in multiple places, or when the material itself has degraded past the point where sealing will hold. We repair because that’s one of our three services, and we’ll tell you plainly when repair won’t solve the problem rather than sell a fix that won’t last.
FAQs – Duct Repair & Sealing Cost
How much does duct sealing cost in Spokane?
Duct sealing in Spokane typically costs $350 to $800 for accessible joints and seams. The range depends on how many joints are reachable and whether the ductwork sits in an attic, crawlspace or basement. Call (866) 963-7098 for an exact quote. Estimates are free.
How much does it cost to repair a disconnected duct in Spokane?
Repairing a single disconnected or crushed duct run in Spokane usually runs $250 to $550, including reconnecting it at the register boot and the plenum. Multiple runs push the total to $600 to $1,500. Call (866) 963-7098 for a free estimate on your system.
Can you come today?
Usually, yes. Same-day service is available for most duct repairs in Spokane when you call in the morning. Call (866) 963-7098. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm.
Is it cheaper to repair or replace ductwork?
Repair is cheaper in nearly every case where the ductwork is structurally sound: $250 to $1,500 for repairs versus several thousand for a full replacement. Replacement only makes sense when the duct sizing is wrong or the trunk line has failed in multiple places. Call (866) 963-7098 and we’ll tell you which one your system actually needs.
Does duct sealing really save money on energy bills?
Sealing ducts that leak into an attic or crawlspace reduces the conditioned air you’re paying for and losing. The actual savings depend on how leaky the system was, which is why we diagnose before quoting. What we can tell you is that a system losing air through separated joints is working harder than it needs to. Call (866) 963-7098 for a free estimate and a straight answer about what your ductwork needs.

If your energy bills have crept up, if certain rooms never get comfortable, or if you’ve had ductwork installed or worked on and never had the joints checked, the repair is usually smaller than the worry. We’ll look at the system, tell you what’s actually failing, and put a written estimate in front of you before anything starts. Duct repair, duct cleaning and dryer vent cleaning are the three things we do, and we do them with Rotobrush, Nikro and Abatement Technologies equipment rather than a shop vac and a guess.
