Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Arden-Arcade
Duct sealing in Arden-Arcade typically runs $850 – $2,400 for a whole-home system, depending on how much of the original 1950s – 60s ductwork needs rejoining, resizing, or replacement. Most jobs take a full day and are scheduled within a week of your call. You can reach our Arden-Arcade crew at (361) 326-5060 for a free written estimate.
We’ve worked the ranch tracts from Sierra Oaks to Del Paso Country Club and along the American River Parkway corridor. These homes share a common problem: duct systems built for gravity furnaces and early forced-air, not for the sealed, high-static HVAC units homeowners install today. Our dispatch and scheduling are coordinated from our Sacramento office, but the crew that pulls up to your driveway knows Arden-Arcade’s housing stock because we’ve sealed and repaired it for years. Roy Castellanos built this operation on The Garrison Standard: arrive inside the window, price it in writing before we touch anything, and leave the site clean.

Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In Arden-Arcade, that longevity means we’ve crawled through enough slab-on-grade attics and utility closets to know where the original galvanized trunks fail, where early flex branches sag, and how the heavy oak canopy along the Parkway feeds debris into exterior vents.

Duct Repair in Arden-Arcade
Duct Repair in Arden-Arcade means fixing the mechanical failures that cleaning alone won’t solve. In this market, we’re typically rejoining separated galvanized seams, replacing crushed flex branches, and rebuilding register boots that have pulled away from slab edges. A straightforward repair on a single run runs $280 – $650. More extensive work involving multiple branches or trunk line access can reach $1,200 – $1,800.
Corroded Galvanized Trunks
Original galvanized steel ductwork in Arden-Arcade’s 1950s – 60s ranches corrodes at seams and joints, leaking 20 – 30% of conditioned air into the slab cavity or attic. We cut out the failed section, fabricate a replacement, and seal with mastic and reinforcing mesh. The fix holds because we pressure-test before we leave.
Crushed or Disconnected Flex
Early flex duct from the 1960s – 70s sags between trusses, gets crushed by storage in attics, or disconnects at the boot when other trades work nearby. We replace with properly sized flex, support it to prevent sag, and seal the connection with mechanical fasteners and mastic. No tape-only fixes.
Air Duct Sealing in Arden-Arcade
Air Duct Sealing in Arden-Arcade addresses the conditioned air you’re paying to heat and cool that’s escaping before it reaches your rooms. In a typical Arden-Arcade ranch, we measure 25 – 40% leakage on pre-1970 duct systems. Whole-home sealing runs $850 – $2,400 depending on system size, access difficulty, and whether we’re working with original galvanized or newer flex. The payback on your energy bill usually shows within two seasons.
Mastic and Mesh Sealing
We seal accessible joints and seams with duct mastic, a thick water-based compound that remains flexible, reinforced with fiberglass mesh. Unlike foil tape, mastic won’t dry out and peel in Arden-Arcade’s hot attic summers. We apply it to every joint we can reach.
Aeroseal Injection
For systems with limited access, we offer aerosolized sealant injection that seals leaks from the inside. We pressurize the duct system, measure baseline leakage, then inject sealant particles that bond at leak points. Post-test verification proves the reduction. This method adds $400 – $800 to a standard sealing job but reaches leaks behind walls and slab edges that hand-sealing cannot.
Trusted Brands We Service in Arden-Arcade
Our Duct Sealing team carries equipment and materials from Rotobrush, Nikro, Honeywell, Aprilaire, and Abatement Technologies. We stock mastic, mesh, mechanical fasteners, and replacement flex duct sizes common to Arden-Arcade’s ranch-style homes, so we’re not running to the supply house mid-job. For filtration upgrades after sealing, we source Guardsman and Aprilaire media that fit the standard return grilles found in these 1950s – 60s tracts. Fast turnaround matters because a home with leaky ducts is a home where the HVAC runs overtime and the utility meter spins.
Common Duct Sealing Problems We See in Arden-Arcade Homes
- Original galvanized runs corrode at seams and joints, leaking 20 – 30% of conditioned air into the slab cavity and attic before it ever reaches the register. We find this in nearly every pre-1970 ranch we inspect in the Sierra Oaks and Del Paso areas.
- Early flex branches from the 1960s – 70s sag, crush, or disconnect at the boot during other trades’ work, creating a lint pathway that mimics a dirty duct problem. Homeowners call for cleaning when the real issue is a disconnected branch behind the air handler.
- Heavy oak and cottonwood canopy feeds seed pods and leaf litter into exterior vents along the American River Parkway corridor, choking airflow and masking an internal sealing failure. The vent looks like the problem; the leak behind the register boot is.
- Undersized return ducts designed for gravity furnaces can’t handle the static pressure of modern variable-speed air handlers, causing the system to starve for air and whistle at the grille. Sealing helps, but often we need to resize the return path.

FAQs About Duct Sealing in Arden-Arcade
We can seal most original galvanized ducts if the metal is structurally sound. We cut out corroded sections, fabricate replacements, and seal all joints with mastic and mesh. Replacement becomes necessary when the metal is too thin or too perforated to hold sealant. Call (361) 326-5060 and we’ll camera-inspect to give you a straight answer.
The problem is usually a disconnected or crushed flex branch, or an undersized duct run that can’t deliver sufficient CFM. Cleaning removes debris but doesn’t fix mechanical failure. We measure static pressure and airflow at each register to find the restriction, then repair or resize the run. On a 1961 ranch near the American River Parkway corridor, our tech camera-inspected the return and found the original galvanized trunk separated at a 90° boot behind the slab edge, with cottonwood seed pods clogging the exterior vent and oak leaf litter packing the register boot. We performed source removal under negative pressure with HEPA filtration, sealed the joint with mastic and mesh, and reconnected a crushed flex branch off the air handler. The homeowner’s supply and return static dropped and the back bedroom finally reached setpoint.
Yes. We work to NADCA ACR and SMACNA sealing standards on every job, including pre- and post-sealing pressure testing, proper mastic application thickness, and mechanical fastening before sealant. We document the work and provide the results in writing.
Yes. Arden-Arcade’s mild, wet winters introduce moisture through poorly sealed return plenums and slab-edge gaps. Combined with dust accumulation, this creates conditions for mold growth inside ductwork. Sealing the system prevents moisture intrusion and improves indoor air quality year-round. If we find active mold during inspection, we recommend remediation before sealing.
It’s both a blockage issue and a potential masking issue. Heavy leaf litter and seed pods choke airflow, but they also hide internal leaks that are the real problem. We clear the exterior vent, then pressure-test the system to separate blockage from leakage. Often we find both. Call (361) 326-5060 for an inspection.
