AfterHow Much Does Duct Repair & Sealing Cost in Boyle Heights?
Duct repair and sealing in Boyle Heights typically runs $350 to $1,400 for most single-family homes, with small gap-and-joint sealing jobs at the low end and disconnected or crushed duct runs at the high end. Whole-house duct replacement, when the system is beyond patching, lands between $2,200 and $5,500. Most homes we inspect in Boyle Heights fall into that $350 to $1,400 band because the problems are usually junction leaks, failed mastic, and disconnected flex runs, not a full rebuild.
Those numbers come from the market here, not a national average. Boyle Heights housing stock is old. A large share of the homes are 1920s to 1950s bungalows and duplexes, many with attics that bake at 130°F or more in summer and crawlspaces that stay damp through winter. That combination destroys duct tape, mastic, and flex duct faster than the mild coastal climate a few miles west. We see it constantly: equipment that was fine ten years ago when it went in, now leaking at every seam.
Key Takeaways
- Typical duct repair and sealing in Boyle Heights: $350 to $1,400.
- Targeted sealing of accessible leaks: $350 to $650.
- Single duct run repair or replacement: $250 to $600 per run.
- Full duct replacement, when repair won’t hold: $2,200 to $5,500.
- In a city where summer attic temps routinely push past 130°F, sealing is not cosmetic. Leaking ducts can cut system efficiency by 20 to 30 percent.
Duct Repair & Sealing Cost Breakdown (2026)
Most jobs combine a few line items rather than landing on one price. Here’s how the work breaks down in Boyle Heights dollars.
| Service | Typical Price Range |
|---|---|
| Duct inspection and air-leak test | $99 to $250 (often credited toward the repair) |
| Targeted sealing of accessible leaks (mastic and professional tape) | $350 to $650 |
| Whole-system sealing with aeroseal-style or mastic treatment | $900 to $1,800 |
| Single duct run repair or replacement | $250 to $600 per run |
| Disconnected or crushed duct reconnection | $350 to $800 |
| Plenum repair at the air handler | $400 to $900 |
| Insulation wrap replacement on accessible runs | $150 to $450 |
| Full duct system replacement | $2,200 to $5,500 |
| Combined cleaning plus repair and sealing | $700 to $2,000 |
What pushes a job up? Access is the big one. A single-story bungalow off Whittier Boulevard with an open attic and a low-pitch roof is easy to work in. A two-story 1930s home near Hollenbeck Park with an attic packed with knob-and-tube wiring and zero walkway can add $300 to $600 in labor just to reach the problem. Crawlspace ducts in the flats east of the Los Angeles River add time too, since crews work on their backs in confined space.
Duct material matters as well. Older rigid metal ductwork can often be sealed and reused. Collapsed flex duct in a hot attic usually can’t. And if a home has never had its ducts cleaned, we’ll often recommend bundling the cleaning with the repair so you’re not paying twice to move equipment and set up containment. Eastgate handles air duct cleaning and air duct repair as separate services, so you can price them independently or together. Our home page lays out all three core services, and the Duct Repair & Sealing in Koreatown guide shows how the same work prices out in a neighboring market with very different housing.
What Affects Duct Repair & Sealing Pricing in Boyle Heights
- Attic heat and building age. Boyle Heights attics hit brutal temperatures in July and August, and older homes weren’t built with today’s sealed, insulated duct systems. Heat cycling degrades mastic and flex faster here, so repairs run more often and sometimes cover more of the system.
- Foundation type. Many homes on the flats sit on raised foundations with crawlspace ductwork. Confined-space work is slower and requires more care, which adds labor. Homes with attic-only ductwork price lower.
- Number of accessible runs. Sealing a system with eight accessible runs and sealing one with twenty are different jobs. We price per run on repair work, then add the sealing treatment.
- Whether it’s repair or replacement. Patching a disconnected run is cheap. Rebuilding a system someone improperly installed or that rats have chewed through is not. Our crews use Rotobrush and Nikro equipment and Abatement Technologies-grade negative air and HEPA filtration when contamination is a concern, which is a reality in some of these older systems.
- Air quality components. If your home runs a Honeywell or Aprilaire whole-home air quality system, the repair has to account for how that equipment ties into the ductwork. We work with those systems regularly, and it occasionally adds a step to the job.
- Permits. Minor duct repair and sealing generally doesn’t require a city permit. Full duct replacement or work that alters the HVAC system layout can trigger a City of Los Angeles permit and inspection, which adds to the total.
How to Save on Duct Repair & Sealing
The single biggest cost saver is catching leaks early. A $350 sealing job today prevents a $1,800 replacement in five years. Here’s what actually helps in Boyle Heights:
- Get the inspection first. A leak test tells you whether you need a $400 repair or a $3,000 rebuild. Skipping it means guessing, and guessing usually costs more.
- Bundle cleaning with repair. If your ducts are also dirty, doing both in one visit saves on setup and equipment. Combined jobs in Boyle Heights run $700 to $2,000, versus paying separately for each.
- Seal before the summer peak. Getting sealing done in spring, before attic temperatures climb, is more comfortable for crews and lets you catch problems before the cooling season stresses the system.
- Address dryer vent cleaning while we’re there. It’s a separate service, but a lint-clogged dryer vent is a documented fire hazard, and handling it on the same visit saves a trip charge. We treat it as fire-risk work, not an upsell.
- Ask about free estimates. Call (855) 382-4682 for a free estimate. We’ll give you the leak test result and a written range before any work starts.
Can You Fix Duct Leaks the Same Day?
Yes, for most accessible leaks. Sealing jobs on reachable joints and a single disconnected run are typically done in one visit of two to four hours. Jobs that require crawling through tight attic spaces or rebuilding a plenum may need a second trip. When you call, we’ll tell you what to expect based on your home’s layout.
Is It Cheaper to Repair or Replace Ductwork in Boyle Heights?
Repair is almost always cheaper: $350 to $800 for a targeted fix versus $2,200 to $5,500 for full replacement. The question is whether repair will hold. If the ductwork is intact but leaking at seams and joints, sealing it is the right call and can recover a meaningful share of lost efficiency. If the flex duct has collapsed, been chewed through, or the system was installed wrong in the first place, repair is throwing money at a problem that will come back. We’ll tell you which one you’re looking at, and we won’t recommend replacement on an older system that’s structurally sound.
FAQ – Duct Repair & Sealing Cost
How much does duct sealing cost in Boyle Heights?
Duct sealing in Boyle Heights typically costs $350 to $650 for accessible leaks and $900 to $1,800 for a whole-system treatment. The price depends on how many runs we can reach and how bad the leaks are. Call (855) 382-4682 for an exact quote; estimates are free.
How much does it cost to repair a disconnected air duct?
A disconnected or crushed duct run usually costs $350 to $800 to reconnect and reseal in Boyle Heights. If the run needs a full replacement in a tight attic, expect the higher end. This is a common problem in the older bungalows here, and it’s fixable in one visit in most cases. Call (855) 382-4682 to book an inspection.
Is duct repair worth it, or should I just replace the whole system?
Repair is worth it when the ductwork is structurally sound and the problem is leaks, loose joints, or a single failed section. That covers most Boyle Heights homes. Full replacement, at $2,200 to $5,500, makes sense when multiple runs have failed or the system was badly installed. We’ll give you both numbers and let you decide. Call (855) 382-4682 for a free estimate.
Will sealing my ducts lower my energy bill in Boyle Heights?
Yes, in most cases. Leaky ducts in a hot attic can lose 20 to 30 percent of cooled air before it reaches your rooms. Sealing them typically pays back the job within a few cooling seasons here, given what summer electricity costs. Exact savings depend on how bad your leaks are. Call (855) 382-4682 to find out what your system is losing.
Do you need a permit for duct repair in Boyle Heights?
Minor duct repair and sealing generally doesn’t require a permit in the City of Los Angeles. Full duct replacement or work that changes the HVAC system layout can require a permit and inspection, which we’ll flag before any work begins. Call (855) 382-4682 if you’re unsure which category your job falls into.

What Our Customers Say
"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Lucia Mendoza"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Andres Castillo"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
