Roy Castellanos leads our crew, and he knows what Pico Rivera’s older homes throw at a duct system. The 1950s and 1960s tract houses that fill this city were built with materials and methods that are now six or seven decades old. That age shows up in specific ways: corroded galvanized seams, crushed flex runs under slab floors, and gaps that have been pulling dust from crawlspaces for years without anyone knowing it.

Why Hollis Air Duct Pasadena Is Pico Rivera’s Preferred Duct Sealing Company

We’ve worked in enough Pico Rivera homes to know the pattern before we even open an access panel. Homes near Rivera Park, off Paramount Boulevard, and in the neighborhoods east of Rosemead Boulevard tend to share the same original ductwork DNA from the post-war building boom. When we do a Duct Sealing job here, we’re usually not the first company to look at the system, but we’re often the first to find what others missed.

Our technicians arrive in uniform, background-checked, and carrying the same equipment commercial crews use: Rotobrush rotary brush systems and HEPA-filtered negative-air machines from Nikro and Abatement Technologies. Every job gets a written price before work starts, and it doesn’t move once we’re inside. The name on that paper matters. Roy Castellanos signs off on it, and the 365-Day Done Right Promise backs it: if a sealed seam fails within a year, we come back and fix it at no charge. That includes a free second visit. No arguing, no conditions.

Duct sealing in Pico Rivera is something we handle as a local crew, with scheduling coordinated through our Los Angeles office. That means when you call, a live person answers, 24/7, and gets you on the books. No voicemail loops when you’re trying to figure out why one bedroom won’t cool in August.

HVAC Duct Sealing in Pico Rivera

HVAC Duct Sealing is the work of closing every gap, seam, and disconnection in your duct system so the air your furnace or AC pushes actually reaches its registers instead of leaking into the attic, crawlspace, or wall cavities. In Pico Rivera, this matters more than in newer cities because so many ducts are original galvanized steel from the 1950s and 1960s, sealed decades ago with materials that have long since dried, cracked, or fallen away.

Expect to pay $450 – $650 for a standard single-story Pico Rivera home with accessible ductwork and a handful of leaks at seams and takeoffs. Two-story homes or systems with multiple disconnections and crushed runs run $700 – $950. Every estimate is written down before we start.

Finding the leaks that matter

We don’t guess. We inspect the accessible duct runs, often with a camera, to see exactly where air is escaping. On a 1962 home near Rivera Park, our tech spotted a crushed return trunk during a camera inspection: original galvanized steel, corroded at the seams and disconnected in two places. We used Rotobrush agitation tools and HEPA-filtered negative pressure to clear the debris, then sealed the supply and return ducts with mastic and metal tape, bringing static pressure back in line with NADCA standards. That’s the kind of failure you can’t see without looking.

Most of our Pico Rivera customers call because of a symptom, not a diagnosis: one bedroom that stays hot, a living room that gets dusty three days after vacuuming, a furnace that smells like burnt dust every fall. Those symptoms almost always trace back to duct leaks.

Duct Repair in Pico Rivera

Duct Repair goes beyond sealing seams; it means replacing sections of duct that are crushed, corroded through, disconnected, or so degraded that mastic alone won’t hold. In Pico Rivera, this often means repairing or replacing original galvanized steel runs that have rusted at the joints, or flex duct under slab foundations that has collapsed from decades of settling.

Repair costs in Pico Rivera generally run $250 – $450 per section, depending on access and material. A complete repair job, where we replace multiple crushed or separated sections and then seal the remaining system, typically lands between $600 and $1,100 for a mid-century single-family home. The written quote you get before we begin breaks this down line by line so you know exactly what you’re paying for.

When sealing alone won’t fix it

Some Pico Rivera homes need more than sealing. Crushed flexible ducts under slab foundations, common in 1950s tract homes, restrict airflow so badly that sealing alone can’t fix the imbalance. The fix is to replace the collapsed section first, then seal the rest of the system. A homeowner who only seals can spend good money and still have a hot bedroom come July.

The Garrison Code we operate under is simple on paper but rare in practice: arrive inside the quoted window, price it in writing, complete the job by the book, and leave the site clean. On a repair job that might mean cutting out a corroded section, fitting a replacement, sealing the connections with mastic, and hauling the old material out of your attic instead of leaving it there.

Trusted Brands We Service in Pico Rivera

The equipment in your Pico Rivera home carries some combination of names, and we work with all of the common ones: Aprilaire filtration units, Abatement Technologies negative-air setups, Guardsman products, and anything tied to Rotobrush or Nikro systems. We stock the mastics, tapes, and replacement fittings that older systems need, so most repairs happen same visit rather than after a parts run across town. If your ducts were patched years ago with the wrong materials, like cloth duct tape that dried and fell off, we’ll remove it and replace it with the right product. That single change often makes a larger difference than homeowners expect, and it’s part of why our Pico Rivera customers see dust levels drop within the first week.

Common Duct Sealing Problems We See in Pico Rivera Homes

• Corroded galvanized seams from the 1950s and 1960s. The original zinc coating lifts over time, especially in Pico Rivera’s dry air, leaving rusted edges that flex apart. Mastic applied over a corroded seam often fails within a year because there’s no sound metal underneath to bond to; the seam needs mechanical repair first, then sealing.
• Cloth duct tape that dried out and fell off. Past handymen used standard duct tape and in Pico Rivera’s low-humidity heat, the adhesive bakes out and the tape peels away. Every supply run that opens up again becomes a leak that pulls dust from the attic or crawlspace into the air you breathe.
• Crushed or collapsed flex duct under slab foundations. Many 1950s tract homes in Pico Rivera have ducts run through or under the slab, and decades of settling plus occasional Santa Ana-driven grit intrusion can flatten entire sections. Sealing can’t restore airflow through a collapsed run; replacement is the only fix, and if only some rooms are affected, this is usually why.
• Dusty heater smell on the first cold snap. That smell is the residue of decades of accumulated debris heating up and blowing through leaks. In Pico Rivera, freeway proximity means fine particulate matter from I-5 and the 605 settles into duct systems, then stays there when low humidity keeps it airborne instead of dropping out.
