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 Rocklin
We’re the crew Hollis Air Duct Cleaning sends to Rocklin when homeowners notice dust streaks around their ceiling vents, rooms that never cool evenly, or that persistent smoke odor that lingers months after fire season ends. Dispatch and scheduling run from our Sacramento office, but our trucks roll into Rocklin neighborhoods like Whitney Ranch, Stanford Ranch, and the older pockets off Sierra College Boulevard with the tools and mastic already on board. If you’re seeing signs your ducts are leaking, call us at (361) 326-5060. We’ll give you a written price before any work starts, and every seal we make carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Rocklin’s Preferred Duct Sealing Company
We’ve been doing this since 2004 as part of the Garrison Partners family, and Rocklin’s combination of 1990s-built suburban homes, rural-edge properties, and wildfire exposure creates duct problems we recognize before we even pull the camera out. Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean.
When we seal ducts in Rocklin, we’re not guessing at the leak path. We run camera inspection first, especially on two-story homes where the upstairs return trunk often separates from the flex-duct collar in attic heat. Our pricing is written down before we touch anything, and it does not move at the door. If our seal fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal promise; it’s printed on every job sheet.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to get on the schedule.
HVAC Duct Sealing in Rocklin
HVAC Duct Sealing in Rocklin is the process of closing gaps, separations, and deteriorated connections in your forced-air system’s ductwork so conditioned air reaches the rooms it’s supposed to reach, and contaminated attic or crawlspace air stays out. In Rocklin’s housing stock, built heavily in the 1990s and 2000s, flexible ductwork runs through unconditioned attics that hit 140°F in July and pull ash through every loose collar during fire season. A typical whole-system seal in Rocklin runs $850 – $1,800 depending on accessibility, the linear footage of compromised duct, and whether we need to replace degraded flex sections before sealing.
We seal with mastic compound and foil-backed tape rated for high-temperature attics, not the cloth duct tape you’ll find at hardware stores that dries out and fails within a season. Our equipment includes negative-air machines from Nikro and rotary brush systems from Rotobrush to source-remove contamination before we seal, so we’re not trapping dust inside a newly closed system.
When Sealing Should Come Before Cleaning
In Rocklin, homes on the rural edges near Whitney Ranch and the open land toward the foothills pull dust and ash from unpaved roads into return ducts that sit in unconditioned attics, so duct sealing there is less about saving energy and more about keeping a contaminated attic air path out of the living space. The result is that sealing often needs to happen before cleaning is complete, otherwise the negative pressure from the system pulls that attic dust right back through the leaks. We assess this on every job. If your return trunk has separated from the air handler cabinet, cleaning first is wasted money.
Fire-Season Urgency
After major wildfires, standard filters are overwhelmed and fine ash coats duct interiors. Sealing in October or November, before the winter heating cycle begins, prevents that ash from recirculating through your home for months. We see the surge in calls every year. Schedule the inspection early.
Duct Repair in Rocklin
Duct Repair in Rocklin addresses physical damage to your ductwork: crushed flex runs from contractors walking through attics, rodent-chewed sections, rusted metal trunk lines from roof leaks, and collars that have pulled completely free from the main trunk. A typical repair in Rocklin runs $300 – $750 for isolated damage, or $1,200 – $2,400 if multiple trunk sections need replacement. We always inspect with a camera before quoting, so you’re not paying for repair on a duct that actually needs full replacement.
Rocklin’s two-story homes, common in Stanford Ranch and the developments off Park Drive, often have upstairs duct runs that fail independently from downstairs systems. The attic heat accelerates flex-duct deterioration, and the longer runs to second-floor rooms create more pressure points where collars separate. We check both zones separately.
Common Rural-Edge Damage
Properties near unpaved roads see accelerated duct contamination and physical damage from vibration transmitted through the structure. We’ve found flex duct pulled loose from its hanger straps on homes off the rural edges, where heavier vehicle traffic on gravel roads creates more mechanical stress than suburban streets. We re-strap and seal these runs with hardware rated for that environment.
Camera-Guided Targeting
Skipping camera inspection on two-story Rocklin homes and sealing the wrong branch is a mistake we see from crews who rush. Upstairs ducts near attic heat often have separate leaks from the downstairs trunk. A partial seal leaves the smoke-odor path intact. We map the system before we commit to a repair scope, and we show you the footage.
Trusted Brands We Service in Rocklin
We carry professional-grade equipment and materials from Rotobrush, Nikro, Aprilaire, and Abatement Technologies on every Rocklin truck. For filtration upgrades after sealing, we stock Honeywell and Guardsman products that match what commercial crews install. Because we dispatch from Sacramento and keep common flex-duct sizes, mastic compounds, and collar hardware on hand, most Rocklin jobs don’t wait for parts. If your system needs an Aprilaire media filter upgrade or an Abatement Technologies HEPA bypass unit after we’ve sealed the leaks, we can install it the same visit. We don’t sell you what you don’t need, but we don’t leave you waiting for a second trip when the right component is on the shelf.
Common Duct Sealing Problems We See in Rocklin Homes
- Attic return trunk separation in 1990s flex-duct systems. Rocklin’s planned communities like Whitney Ranch and Stanford Ranch were built with flexible ductwork in unconditioned attics. The return trunk often separates at the collar connection to the air handler, creating a direct path for attic dust, insulation fibers, and wildfire ash into your breathing air. Camera inspection finds it every time.
- Standard duct tape failure in 100°F+ attic heat. We regularly remove failed cloth duct tape or low-grade mastic that was applied by a previous service or a DIY attempt. The adhesive cooks off within a season, reopening the same leak path and sometimes making it worse by trapping moisture against the duct surface.
- Two-story homes with independent upstairs leaks. The upstairs duct runs in Rocklin’s two-story homes sit closer to attic heat and experience more thermal expansion cycles. They leak separately from downstairs trunks, creating the smoke-odor and dust-streak pattern homeowners notice first in second-floor bedrooms.
- Rural-edge dust loading from unpaved roads. Homes on the edges of developed Rocklin, toward the open land and foothills, pull measurable quantities of road dust into returns. Sealing without addressing the active dust source, or cleaning without sealing the leak that admits it, wastes the homeowner’s money and leaves the problem recurring within months.
Pricing for Duct Sealing in Rocklin, CA
A typical whole-system duct sealing in Rocklin runs $850 – $1,800. Isolated repairs on one or two compromised runs run $300 – $750. Full replacement of degraded trunk sections on larger homes, or systems requiring both sealing and cleaning before the seal, can reach $1,200 – $2,400. What moves the number: accessibility of your attic or crawlspace, the linear footage of duct that needs attention, whether we need to replace collapsed or rodent-damaged flex sections before sealing, and whether your system needs HEPA source removal of wildfire ash prior to closure.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing, no add-ons at the door, no teaser coupon that balloons once the technician is inside. We also provide before-and-after photos of your own ducts, so you see what was leaking and what we closed. Estimates are free.

FAQs About Duct Sealing in Rocklin
Every 18 to 24 months for properties on or near unpaved roads, versus the 3- to 5-year interval that works for filtered suburban systems. The dust loading is continuous and abrasive, so collar connections and mastic seams degrade faster. Call (361) 326-5060 to schedule a camera inspection and we’ll tell you if your seals are still intact.
Yes, but only if the seal targets the correct leak path. Smoke odor persists when ash-laden attic air is pulled through return trunk separations into the supply side. Sealing those specific paths, combined with HEPA source removal of settled ash, eliminates the odor source rather than masking it. We see this pattern repeatedly in Rocklin homes after major fires like the Camp Fire and Caldor Fire.
Yes. Nearly all residential duct sealing we perform in Rocklin is done through attic and crawlspace access points, with camera guidance to locate leaks we can’t see directly. We use extendable mastic applicators and foil tape to reach tight spaces. Wall demolition is rarely necessary for standard flex-duct and metal trunk systems.
The upstairs return and supply trunks run closer to attic heat, which accelerates flex-duct deterioration and creates more aggressive negative pressure at leak points. Hot attic air rises, and in Rocklin’s 100°F+ summers that attic air carries more ash and dust load. The upstairs registers are often the first place homeowners notice dust streaks and odor. Camera inspection almost always reveals separate leaks from the downstairs system.
No. If your ductwork has been extended to a detached shop or outbuilding with its own return path, sealing the main house ducts does not address contamination entering at the outbuilding end. That requires separate assessment and potentially dedicated filtration or a separate system. We can evaluate the full layout and tell you where the dust is actually entering. Call (361) 326-5060 for an exact scope and written price.
