AfterHow Much Does Duct Repair & Sealing Cost in Pomona?
Duct repair and sealing in Pomona typically runs $350 to $1,800 for most homes, with single-joint repairs and small seal jobs near the low end and multi-run replacements or full-house sealing near the high end. A straightforward sealing job on accessible attic ductwork often lands around $450 to $750. Larger repairs where flex duct has torn loose in several places, or where a return chase needs rebuilding, push toward the top of that range.
That range reflects what we actually see working in Pomona homes: older housing stock, hot inland summers that cook attic flex duct, and a lot of add-on room conversions where ductwork was run fast and never sealed. If you want a number for your house rather than a range, duct cleaning Pomona starts with an inspection, and the written estimate sets the final price.
Key Takeaways
- Most duct repair and sealing jobs in Pomona fall between $350 and $1,800.
- Sealing accessible joints and seams is usually the cheapest fix and the highest-impact one.
- Repair and cleaning are often done on the same visit, since a repaired duct still needs to be clean.
- Free estimates, and the written estimate – not a phone guess – sets the price.

Duct Repair & Sealing Cost Breakdown (2026)
Here’s how the work breaks down by line item. These are estimated ranges for the Pomona market in 2026, not quotes. Every job gets priced from what we find on site.
| Scope of work | Typical estimated range |
|---|---|
| Sealing a few accessible joints and seams (mastic or foil tape plus mastic) | $150 – $350 |
| Whole-system sealing of accessible duct runs | $450 – $900 |
| Single flex duct run replacement (torn, crushed or disconnected) | $250 – $550 |
| Multiple run replacements (3-5 runs) | $700 – $1,500 |
| Return air chase rebuild or major trunk repair | $900 – $1,800 |
| Reconnecting and resealing a disconnected plenum or trunk joint | $350 – $800 |
| Duct cleaning combined with repair (recommended on most repair visits) | Repair range plus the cleaning scope |
What pushes a job up? Access is the big one. Ductwork buried under blown insulation, runs packed into a low attic with limited clearance, or a chase inside a wall all take longer and cost more. Down low, you get cheaper pricing when the problem is isolated and reachable – one torn run near the air handler, a handful of leaking joints you can actually get a hand to. Materials matter less than labor on this work, so the layout of your house drives the number more than the parts list does.
One thing worth saying plainly: we don’t quote sight unseen. Anyone who gives you a firm duct repair price over the phone without opening the attic is guessing, and the written estimate is what actually governs the job.
What Affects Duct Repair & Sealing Pricing in Pomona
Pomona isn’t a generic market. A few local conditions move the price up or down more than homeowners expect.
- Attic heat and duct condition. Inland Valley summers push attic temperatures high enough that flex duct degrades faster here than in cooler parts of Southern California. Duct that has been baking for a couple of decades gets brittle, and brittle duct tears at the connections. We see a lot of it.
- Age and type of the housing stock. Pomona has a wide mix of older single-family homes and mid-century tract housing. Homes from the mid-20th century often have original sheet metal trunk lines with flex branches added later, which means mixed materials and more connection points to seal.
- Where the ductwork runs. Attic runs are the most common and usually the most accessible. Ductwork in a crawlspace or a tight chase takes longer to reach and costs more to work on.
- Whether the system has been “cleaned” before by a blow-and-go crew. Air pressure alone doesn’t remove debris stuck to duct walls, and it doesn’t find loose joints. When we arrive after a cheap cleaning, we often find the same problems plus new ones – crushed flex where someone shoved a hose through it.
- How much of the system is actually accessible. Sealing only helps on ductwork you can reach. If significant portions are buried, the estimate will explain what we can and can’t get to, rather than promising a full seal.
- Whether repair and cleaning are done together. Doing both on one visit is more efficient than two separate trips, and it’s the right order of operations: clean the system, then fix what the cleaning exposed.
That last point is where our approach differs. Most companies either clean or repair. We do both, and we use equipment that holds up to what we find – the Rotobrush contact-cleaning system scrubs duct walls with rotating brushes instead of just pushing debris with air, and Nikro HEPA negative-air machines pull contaminants into containment rather than recirculating them through the house. Abatement Technologies filtration rounds out the airborne particle control. We also work alongside Honeywell and Aprilaire indoor air quality systems regularly, so we understand what the ductwork is feeding.
If you’re weighing a cleaning against a repair, our Pomona service page lays out what each visit covers.
How to Save on Duct Repair & Sealing
There are real ways to keep this bill down without cutting corners that cost you later.
- Fix leaks before they become tears. A leaking joint that goes unsealed lets conditioned air escape, and in a hot attic that escaping air can carry moisture that degrades the duct around it. Sealing early is the cheap version of this job.
- Bundle repair with cleaning. If your ducts are due for cleaning anyway, doing both on one visit saves a second trip and lets the technician repair what the cleaning uncovers. It also means the system is clean when the repair is finished.
- Get the estimate in writing before work starts. Free estimates, and the written price is the price. Anyone who won’t put it in writing isn’t giving you an estimate.
- Ask what’s accessible. A realistic scope that seals what can be reached beats an optimistic one that can’t be delivered.
- Don’t skip the dryer vent. It’s a separate system, but if you’re already scheduling a visit, having the dryer vent cleared at the same time is efficient. Dryer vent cleaning is a fire-prevention service, not an upsell – lint buildup in a vent line is a real fire risk.

Can Duct Repair and Sealing Be Done in One Visit?
Yes, most repair and sealing jobs are completed in a single visit. Sealing accessible joints and replacing a torn flex run are typically a few hours of work. Larger jobs – multiple runs, a return chase rebuild, a trunk repair under a packed attic – can run into a second visit if the scope is bigger than what one crew can finish in a dispatch window.
When we arrive, we open the system up and show you what we found. That’s part of how we work: you see the torn run, the disconnected joint, the crushed section, not just a line on an invoice. Call (833) 589-9571 for a free estimate.
Is It Cheaper to Repair Ductwork or Replace It?
Repair is almost always cheaper than replacement in the jobs we see, and it’s usually the right call. A torn flex run costs a few hundred dollars to replace; tearing out and rebuilding a whole trunk system costs many times that. Replacement only makes sense when the ductwork is structurally failing across most of the system, which is uncommon.
What we won’t do is sell a full replacement when sealing and targeted repairs will fix the problem. If you’ve been told your ducts need replacing, a second look is worth it. Call (833) 589-9571 for a free estimate.
Why Does Duct Repair Cost More After a Cheap Cleaning?
Because air-pressure cleaning pushes debris around without removing it from duct walls, and the equipment used isn’t built for containment. When a crew blows through a system with a shop vac and a blower, they can crush flex duct, dislodge connections, and spread contaminants into the living space instead of extracting them. Repairing that damage adds to the bill.
We use the Rotobrush contact-cleaning system to scrub duct surfaces with rotating brushes, and Nikro HEPA negative-air machines to pull contaminants into containment. It’s abatement-grade equipment, and it’s why we can find and fix what’s actually wrong instead of just reporting it. Call (833) 589-9571 for a free estimate.
FAQs – Duct Repair & Sealing Cost
How much does duct sealing cost in Pomona?
Duct sealing in Pomona typically runs $150 to $350 for a few accessible joints and $450 to $900 for whole-system sealing of reachable ductwork. The range tracks with how much of the system can actually be reached. Call (833) 589-9571 for an exact quote – estimates are free.
How much does it cost to replace a torn duct run in Pomona?
A single flex duct run replacement typically costs $250 to $550 in Pomona, depending on access and run length. Three to five runs together usually fall between $700 and $1,500. Call (833) 589-9571 for an exact quote.
Do I need duct cleaning before or after repair?
Clean first, then repair. Cleaning exposes the joints and runs that need fixing, and repairing a system that’s still full of debris means the new ductwork starts dirty. Doing both on one visit is the efficient path. Call (833) 589-9571.
Is duct repair covered by a free estimate?
Yes. The estimate is free, and the written estimate sets the final price. We inspect the system, show you what we found, and price the work from there. No phone guess, no surprise number. Call (833) 589-9571. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Can you do duct repair and dryer vent cleaning on the same visit?
Yes, and it’s often worth doing together if the dryer vent is due. Dryer vent cleaning is a dedicated fire-prevention service, not an add-on, and combining visits saves a trip. Call (833) 589-9571 for a free estimate.

- Gilbert Reyes"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
