AfterHow Much Does Duct Repair & Sealing Cost in Richardson?
Duct repair and sealing in Richardson typically runs $250 to $600 for minor leak sealing, $450 to $1,200 for repairing disconnected or crushed flex runs, and $900 to $2,800 for larger restoration work where several sections of ductwork need rebuilding. The written estimate you get after we inspect the system sets the final price, and that estimate is free.
What you pay depends less on the square footage of your house than on what’s actually wrong inside the duct system. A run that has slipped off a collar in the attic is a quick fix. A trunk line crushed during a past remodel, or flex duct sagging and torn above a garage, is a different job entirely. Richardson’s housing stock runs from 1960s ranch homes near downtown to newer construction up in the Palisades, and the ductwork in each tends to fail in its own way.
We’re a duct specialist, not a general HVAC contractor. That matters here because it means we can clean the system with professional-grade Rotobrush and Nikro equipment and then repair the compromised sections that let contaminants back in.
Key Takeaways
- Minor duct sealing in Richardson runs roughly $250 to $600.
- Repairing or reconnecting a single failed run typically costs $450 to $1,200.
- Multi-section restoration can reach $900 to $2,800.
- Sealing alone doesn’t fix crushed or disconnected ductwork. Repair has to come first.
- Our technicians have up to 15 years of experience, and estimates are free.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s how the work usually breaks down for Richardson homes. These are typical ranges for the local market in 2026, not a quote for your specific system.
| Work Item | Typical Range |
|---|---|
| Sealing accessible joints, collars and seams with mastic | $250 – $600 |
| Reconnecting a disconnected flex run | $450 – $900 |
| Replacing a crushed or torn flex run | $550 – $1,200 |
| Rebuilding a damaged trunk line section | $900 – $1,800 |
| Multi-run restoration (three or more compromised sections) | $1,500 – $2,800 |
| Duct cleaning added to repair (whole home) | $350 – $700 |
| Registers and grilles replaced during repair | $40 – $120 each |
What pushes a job toward the top of those ranges? Attic access, mostly. A duct system that’s buried under blown insulation, wedged into a tight knee wall, or routed through a low-clearance space above a second-story ceiling takes longer to reach and longer to repair properly. Ceiling and drywall access, if a run is enclosed inside a soffit or wall chase, adds labor too. On the other end, accessible flex duct in an open attic with a clean run to the plenum can often be sealed and repaired in a single visit.
Rebuilding a trunk line costs more than patching a branch run because it’s structural work, not just sealing. We’re rebuilding the pathway the whole system depends on. That’s also why it’s worth fixing rather than working around. A crushed trunk sends conditioned air through a smaller opening than the system was designed for, and the pressure backs up into every room downstream.
What Affects Duct Repair & Sealing Pricing in Richardson
Several factors move the number up or down. Here are the ones we see most often in Richardson.
- What kind of duct you have. Flex duct is cheaper to repair and replace than rigid metal or ductboard. Many Richardson homes built in the 1970s and 1980s have a mix, with flex branches feeding off a rigid trunk. Mixed systems take extra care to seal where the two meet.
- Where the duct sits. Ducts in a vented attic see bigger temperature swings than ductwork inside a conditioned space, and that stress is part of why joints open up over time. Repairs in an attic are also slower because of access and heat, and that labor shows up in the estimate.
- How many runs are compromised. One disconnected collar is a simple repair. Four failing connections in the same attic point to a larger installation problem, and that costs more to correct.
- Access. A hatch wide enough to move equipment through cuts labor time. A run boxed into drywall adds cutting and patching to the job.
- Whether cleaning is needed at the same time. If the system hasn’t been serviced in years and dust has been pulling through leaks for that long, cleaning before repair makes sense. It also costs less combined than booking the two separately.
- Age and condition of registers and grilles. Battered grilles that no longer seal against the ceiling or floor leak air at the edges. Replacing them during the repair closes a leak that would otherwise stay open.
How to Save on Duct Repair & Sealing
Saving here isn’t about finding the cheapest quote. It’s about spending once and getting the problem actually closed.
- Get the repair scoped before the cleaning. Cleaning a duct system with disconnected or crushed runs pushes air into places it shouldn’t go. Repair first, then clean, and you won’t pay twice for the same area.
- Bundle the work into one visit. If ducts need cleaning and repair, having both done in one trip saves you a second round of access and setup. We can also supply and install Honeywell and Aprilaire filtration products during that same visit, which upgrades the air quality system rather than just patching it.
- Use an experienced technician’s eyes. Our technicians have up to 15 years of experience, and they know what a failing connection looks like before it fully separates. Catching leaks early keeps small sealing jobs from becoming large rebuilding jobs.
- Ask for the free estimate in writing. The written estimate lays out exactly what’s being repaired, sealed and replaced. Compare line items between estimates, not just totals. If one quote is much lower, ask what it leaves out.
- Fix the root of the re-contamination. Sealing a leak but leaving the crushed run next to it means dust keeps getting back into the air you breathe. Repair and seal together, and the system stays clean longer.

Why Duct Repair Matters More Than the Price Tag
Price matters. The condition of your indoor air matters more.
Compromised ductwork does two things at once. It leaks conditioned air into the attic, which is wasted money on your utility bill, and it pulls unfiltered attic dust into the return side of the system. In a Richardson summer, when the system runs long hours, that’s a lot of dust pulling into your living space. It’s the reason people with new allergy symptoms often find the source in the ductwork rather than the vents.
That’s also why the repair has to be a real repair. Professional-grade sealing, patching, and rebuilding with the right materials is what stops the leak for good. We bring that equipment to every job, including Nikro HEPA-rated vacuum systems for capturing particulate and Abatement Technologies air filtration units to protect indoor air while the work is underway. When people ask why we use equipment from a company that normally handles contaminant remediation projects, this is the answer: dust and debris disturbed by repair work need to be contained, not just swept around.
We also do ductor cleaning as its own service, and that’s worth knowing. Repair without cleaning leaves years of settled dust behind a now-sealed system. Cleaning without repairing leaves the leaks open. Having one company do both, with the repair and the cleaning sequenced correctly, is the difference between a job that holds and a job that has to be done again.
What’s Included in Duct Repair & Sealing
An estimate from us covers the full scope of the repair, not just the visible fix.
- Inspection of the accessible duct system. We look at the plenum, the trunk, the branches, and the connections at each register.
- Identification of disconnected, crushed or torn runs. Some are obvious. Others only show up when you trace the airflow.
- Reconnection and resealing of joints. Mastic at the collars and seams, applied so the seal holds.
- Replacement of compromised flex runs. Torn or crushed sections are replaced, not patched over.
- Verification after the repair. We check airflow at the registers once the work is done.
- A written estimate before work begins. Pricing is set per job by that written estimate, so there are no surprises.
If you’re also thinking about the dryer vent, that’s a separate safety item and one we treat seriously. Lint buildup in a dryer vent is a code-recognized fire risk, not a minor maintenance chore. It’s worth having both checked. If you’re outside Richardson, you can see the same service on our Richardson page.
How Do You Know You Need Duct Repair Rather Than Just Cleaning?
Uneven airflow between rooms, a musty smell when the system starts, dust appearing right after a professional cleaning, or a room that never gets cool are the usual signs of a leaking or disconnected duct. If one room in the house is consistently hotter or colder than the rest while the system runs normally everywhere else, that pattern usually points to a physical duct problem rather than a dirty system.
Loud whistling at a register or a noticeable pressure difference when you open a door can also point to a leak somewhere in the path. A trained eye finds it faster than a homeowner can by feel alone. If the signs are there, call (877) 741-8677 and we’ll talk through what we’d check first. Estimates are free.
FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Richardson?
Duct repair in Richardson typically costs $450 to $1,200 for a single compromised run, and $900 to $2,800 for larger restoration where several sections need rebuilding. Simple sealing of accessible joints usually runs $250 to $600. Call (877) 741-8677 for an exact quote. Estimates are free.
Is it cheaper to repair or replace ductwork?
Repair is almost always cheaper than replacing an entire duct system. A repair in the $450 to $1,200 range handles the failed sections, while full replacement is a substantially larger project. Replacement becomes the better answer only when the ductwork is failing in many places at once or the system design itself is the problem. Call (877) 741-8677 and we’ll tell you which situation you’re in.
Do I need duct cleaning at the same time as the repair?
Usually yes, and cleaning typically adds $350 to $700 for a whole-home job. If the system has been pulling attic dust through leaks for a while, cleaning before you seal it up is the right order. Cleaning after a repair without cleaning the settled dust that came through the leaks means that dust stays in the system. Call (877) 741-8677 to get both scoped in one estimate.
Can a duct leak actually raise my energy bill in Richardson?
Yes. Leaking ducts move conditioned air into the attic instead of the rooms, so the system runs longer to reach the same temperature. In a Richardson summer that extra run time shows up on the utility bill, and the effect is compounded when the leak is in a hot attic rather than a conditioned space. Call (877) 741-8677 to have the system checked. The estimate is free.
How long does a duct repair take?
Most single-run repairs take a few hours. Multi-run restoration on a larger system can take most of a day. The written estimate gives you the actual window for your job, and dispatch is available with fast dispatch from 7am to 7pm, Sunday through Friday. Call (877) 741-8677 to book a visit.
Do you use professional equipment for the sealing work itself?
Yes. We bring Rotobrush rotary-brush systems and Nikro HEPA-rated vacuum equipment to every job, and we use Abatement Technologies air filtration units to contain dust while the repair is in progress. That matters because the work disturbs dust and debris, and containing it is the difference between a clean repair and a repair that spreads dust through the house.
Can you install upgraded filtration during the same visit?
Yes. We supply and install Honeywell and Aprilaire whole-home air quality products, so filtration can be upgraded at the same time as the repair. That’s often the moment it makes the most sense, since the system is already open and anyone with allergy symptoms is going to want the filter side addressed, not just the leaks. Call (877) 741-8677 to plan it in one visit.
