Why Hollis Air Duct Pasadena Is Atwater Village’s Preferred Duct Sealing Company
We’ve worked on hundreds of Atwater Village homes since Hollis Air Duct was founded in 2004 as part of the Garrison Partners family, including our Dryer Vent Cleaning in Atwater Village. Our techs know the difference between a sealed duct run on Glendale Boulevard and a leaky original run off Seneca Avenue, because those two houses were built by different hands and have aged differently. We show up inside the quoted window, in uniform, with a background-checked crew. The trucks carry Rotobrush rotary brush systems and Nikro negative-air machines, plus sealing mastics rated for the galvanized tin and flex duct found in Atwater Village crawl spaces.
We hold every job to The Garrison Code: arrive inside the window, price in writing, finish by the book, leave the site clean. That code is backed by our 365-Day Done Right Promise. If the repair fails within a year, we come back at no charge including a free second visit. That promise is in writing on every job, not a verbal assurance.
Duct Sealing in Atwater Village is not a side line for us. It is core work, done with professional-grade equipment and a warranty that most local competitors simply do not offer in writing.

HVAC Duct Sealing in Atwater Village
HVAC Duct Sealing in Atwater Village addresses leaks, gaps, and disconnected joints in the metal and flex runs that move air from your furnace or air handler to each register. In these older bungalows, the original galvanized ducts were installed before modern sealing standards existed. Seams loosen, pinholes form, and a significant share of your conditioned air ends up in the crawl space instead of your living room. Typical sealing work in Atwater Village runs $450 to $950 for a single-story bungalow with accessible crawl space ductwork. Homes with asbestos-wrapped ducting or severe rodent damage fall higher, which we explain in writing before we start.
What a standard sealing job covers
We seal accessible joints and seams with duct mastic, replace or reattach loose hangers, repair or replace damaged flex sections, and verify airflow with static pressure readings at the air handler. Every job includes a camera inspection so you can see the before and after with your own eyes.
When sealing is the real fix, not cleaning
If a cleaning removed the dust but a month later the same gray film is back on your furniture, the air is being pulled in through return-side leaks in the crawl space. Sealing those leaks stops the source. A rotary brush cleaning alone cannot fix a leaking duct; it just cleans the duct that is still leaking.
Duct Repair in Atwater Village
Duct Repair in Atwater Village involves replacing crushed runs, rodent-chewed flex, disconnected elbows, and sections where corrosion has thinned the metal beyond what mastic can seal. Our crews find crushed ducts regularly in Atwater Village crawl spaces, where decades of settling plus seismic movement from local fault activity have shifted supports. Repair pricing starts around $180 for a single small section or elbow and typically runs $300 to $700 per repair when we are already on site for a sealing job. Full replacement of a badly damaged trunk line in a larger crawl space can reach $1,200 to $2,400, and we document every section with photos before asking you to approve the price.
Rodent damage repair
In crawl spaces near the LA River greenbelt, rodents gnaw through flex duct and nest inside. We remove the nesting debris, sanitize the surrounding area, and replace the damaged section with new flex and sealed connections. Patching chewed flex is a temporary gesture, not a repair; we replace it.
Asbestos-aware duct repair
Some pre-1980 retrofits in Atwater Village wrapped ducts in asbestos insulation. We do not disturb that wrap. We will tell you what we found, document it, and in some cases refer you to a licensed asbestos abatement contractor before any repair proceeds. Unqualified crews that tear into that wrap create a hazard that lingers in the air.
Trusted Brands We Service in Atwater Village
Our sealing and repair work covers whatever duct materials your Atwater Village home has, from original galvanized tin to newer flex runs. We stock common sizes and fittings locally, which means we are not running to a supply house mid-job. Our equipment roster includes Rotobrush rotary brush systems for source removal and Nikro negative-air machines that keep the work area under negative pressure while we seal, so dust does not migrate into your living space. For filtration questions, we work with Honeywell and Aprilaire products and can explain in plain terms what each filter does for your specific system.

AfterCommon Duct Sealing Problems We See in Atwater Village Homes
- Pinhole leaks at seams on original galvanized ducts. Decades of heating and cooling cycles open tiny gaps along longitudinal seams, and those gaps add up to real air loss. Mastic sealing stops them, but only if the metal is thick enough; we check thickness before we apply.
- Rodent-chewed flex in crawl spaces near the LA River. Greenbelt corridors push rats and mice into crawl spaces. We routinely find nests and chewed flex that a previous contractor patched rather than replaced, and the leak returns within months. We pull the damaged section and replace it.
- Settled or crushed runs under 1920s-1940s homes. Foundation settling from local soil conditions and seismic activity misaligns ducts and crushes runs. A crushed supply duct is not a cleaning issue; it is a repair and sealing issue.
- Asbestos-wrapped ductwork from post-war retrofits. Many Atwater Village homes that added central air in the 1950s through the 1970s used asbestos insulation on the ducts. We identify it, leave it undisturbed, and advise you on next steps before sealing work continues.

FAQs About Duct Sealing in Atwater Village
Rodent damage is common in Atwater Village crawl spaces, especially in homes within a block or two of the LA River greenbelt. Sealing alone cannot fix chewed flex duct; the damaged section must be removed and replaced, then the new connections sealed. We document the damage with photos, remove nesting debris, sanitize the area, and replace what cannot be saved. Call (626) 469-5477 and we will inspect your crawl space and give you a written quote for the repair and sealing work in one price.
Yes, they do. Original gravity-fed systems in 1920s and 1930s Atwater Village homes rely on large, low-velocity ducts that moved air by natural convection before blowers were added later. Those runs are often oversized for modern forced-air equipment, which changes pressure dynamics. We seal them with mastic and, where needed, add supports and hangers to keep the large runs from sagging. The sealing technique is the same material, but the approach to airflow verification is different; we measure pressure at the air handler because gravity-fed retrofits often show uneven flow even after sealing. We explain what the readings mean in plain terms before we finish.
Sealing reduces how much outside air and fine particulates enter the duct system, especially on the return side, but it is not a substitute for cleaning. If your Atwater Village home sits within a quarter mile of the 5 freeway or Glendale Boulevard, the constant soot load means filters clog faster and ducts accumulate a fine black film. We clean the ducts first with a rotary brush system, then seal the leaks so the contamination stops being pulled back in. Done correctly, cleaning without sealing just invites the same soot back within months. Call us for a single flat-rate quote that covers both cleaning and sealing; you will see the before-and-after photos on the spot.
We stop the sealing work on that section immediately and document the finding. We do not disturb, cut, or seal over asbestos wrap. We will explain what we found, show you photos, and advise you on next steps, which may include a licensed asbestos abatement contractor before duct work proceeds. Unqualified crews that tear into that wrap can release fibers into your home, which is a hazard you do not want. After the wrap is properly handled, we can return and complete the sealing work. Call (626) 469-5477 and we will tell you over the phone what to expect, at no charge for the inspection.
That pattern is usually a combination of duct leaks, crushed or disconnected runs, and unbalanced airflow. In Atwater Village bungalows, the far bedroom is often at the end of a long run that has lost significant air through seam leaks along the way, or the run itself has been crushed in the crawl space. We use a camera inspection to find the exact restriction, repair or replace what we find, and then seal the accessible joints. After sealing, we re-measure airflow at each register so you can see the improvement in numbers, not just feel it. Call (626) 469-5477 for a written quote; we will show you the camera footage before any work is approved.
