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.
Fast, Reliable Duct Sealing Across Roseville
Duct sealing in Roseville typically costs $350 – $850 for a whole-home system, and most jobs are completed in a single visit. If you’re losing conditioned air to your attic or pulling dust through gaps in your ductwork, sealing stops both problems at once.
We serve Roseville from our Sacramento scheduling office, with crews running daily routes through Fiddyment Farm, Westpark, and the older streets off Cirby Ranch. We know the difference between a 1970s ranch with rigid galvanized ducts and a 2019 tract home with flex runs strapped too tight in a hot attic. That local knowledge matters because the sealing method changes with the duct type. Call us at (361) 326-5060 for a free estimate, and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Roseville’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team has built a reputation in Roseville by showing up inside the quoted window and leaving the site clean. Roy Castellanos runs our operation, and he insists on The Garrison Standard: written prices, written guarantees, and technicians who arrive uniformed and background-checked.
Roseville homeowners have told us the same story for years. They called another company with a coupon, got a low-ball quote over the phone, and watched the price climb once the technician was inside their home. That doesn’t happen here. The price is written down before we touch your system, and it does not move at the door. Our 365-Day Done Right Promise covers every sealing job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit.

Duct Repair in Roseville
Duct Repair in Roseville covers everything from patching rodent-damaged flexible runs in Fiddyment Farm attics to reinforcing rusted metal seams in older Cirby Ranch homes. We use mastic sealant, mesh reinforcement, and mechanical collars to restore integrity to your system. A typical duct repair in Roseville runs $180 – $450 depending on accessibility and the extent of damage.
When Repair Beats Replacement
Most homeowners assume a leaking duct means tearing everything out. Usually it doesn’t. A torn flex collar, a separated joint, or a pinhole rust spot in rigid metal can be sealed and reinforced for a fraction of replacement cost. We inspect with a camera first, show you what we found, and price the repair in writing before we start.
Rural and Outbuilding Systems
Properties on unpaved roads around Roseville pull more dust into their systems than city homes. Detached garage units and outbuilding flex runs often lack proper return-air seals, creating negative pressure that sucks in road dust. We seal those gaps and reinforce connections so your system stops redistributing outdoor dirt through your living space.
Air Duct Sealing in Roseville
Air Duct Sealing in Roseville is the process of closing gaps, joints, and connection points in your HVAC ductwork so conditioned air reaches your rooms instead of leaking into your attic or crawl space. We seal with mastic, mesh, and mechanical fasteners depending on your duct type. A whole-home sealing job in Roseville typically runs $350 – $850, with most single-family homes falling in the $400 – $650 range.
Flexible Duct Challenges
Newer Roseville subdivisions like Westpark and Fiddyment Farm were built with flexible ductwork that sags and kinks as plastic strapping dries out in our hot, dry summers. Those sags pull connections loose and create gaps where attic dust bypasses your filter. We re-support the runs, re-seat the collars, and seal with mastic rated for the temperature swings your attic sees.
Rigid Metal Restoration
Older homes in Roseville’s core often have galvanized steel ducts that have developed pinhole rust at low points where winter condensation collects. Mastic alone won’t hold on rusted metal. We wire-brush the surface, apply mesh reinforcement, then seal with two coats of mastic so the repair lasts through wet winters and dry summers.
Trusted Brands We Service in Roseville
We carry sealing and filtration products from Aprilaire, Abatement Technologies, and Guardsman, and our equipment roster includes Rotobrush rotary brush systems for pre-sealing cleaning. For Roseville customers, that means we stock the collars, mastic, and mesh reinforcement your specific system needs instead of ordering parts and making you wait. We also service and seal ductwork connected to Honeywell and Aprilaire filtration systems, ensuring your whole-air pathway is tight from the return grille to the supply register. Most sealing jobs in Roseville don’t require a return trip for parts.
Common Duct Sealing Problems We See in Roseville Homes
- Oak debris in attic ducts. In Roseville’s older neighborhoods like Cirby Ranch, mature oak canopies attract squirrels that push acorns and nesting material through failed duct connections. We find this almost never happens in newer tree-less developments where the canopy hasn’t matured.
- Sagged flex runs in newer homes. The dry Roseville summer heat degrades plastic strapping in Fiddyment Farm and Westpark attics, letting flexible ductwork kink and pull free from collars. That kills airflow and pulls hot attic air into your system.
- Rust pinholes in rigid metal. Older galvanized ducts in mid-century Roseville ranches collect condensation at low points during winter rains. The rust starts small but multiplies, and by the time you feel weak airflow at the register, the leak has been bleeding pressure for months.
- Outbuilding dust infiltration. Rural properties around Roseville with detached garages or shop buildings often have flex runs installed with no return-air seal. The system’s negative pressure pulls dust from unpaved roads and open land straight into your living space.
Pricing for Duct Sealing in Roseville, CA
A typical whole-home duct sealing in Roseville runs $350 – $850. Single repairs on accessible flex or metal ducts fall in the $180 – $450 range. What moves you within those brackets: how much of your system is accessible, whether we need to re-support sagging runs before sealing, and if rusted metal requires mesh reinforcement beyond standard mastic.
We do not quote per-vent prices or teaser rates that balloon at the door. You get one flat price per system, agreed in writing before work starts. That price includes all materials, labor, and cleanup. We also provide before-and-after photos of your sealed joints so you can verify the work was done.

FAQs About Duct Sealing in Roseville
Every 2 to 3 years for rural properties on unpaved roads, versus 4 to 5 years for in-town homes with paved streets. The dust loading from unpaved access roads and open agricultural land around Roseville pulls significantly more particulate into your system’s negative pressure zones, accelerating seal degradation. Call (361) 326-5060 and we’ll inspect your current seal condition at no charge.
Yes, because leaky return ducts pull unfiltered attic air during high-pollen months, and Roseville’s surrounding oak woodlands produce some of the highest pollen counts in the Sacramento metro. A sealed system forces all intake air through your filter instead of bypassing it through gaps. If your allergies spike indoors every spring, leaky returns are a likely culprit.
Every 2 years for homes burning wood as primary or significant supplemental heat. Wood stoves produce fine particulate that accumulates in ductwork faster than gas or electric heating, and in Roseville’s climate that means heavier loading during the wet winter months when windows stay closed. Combine that with rural dust from unpaved roads, and your ducts are working harder than the generic “every 3 to 5 years” advice accounts for.
Yes, but sagging flex must be re-supported before sealing or the new seal will fail when the duct kinks again. We replace degraded strapping with metal supports, re-seat the collar connections, then seal with mastic. In Roseville’s dry heat, we see this most often in 10- to 15-year-old homes in Fiddyment Farm and Westpark where original plastic strapping has become brittle.
Because mature oak canopies in neighborhoods like Cirby Ranch support squirrel populations that exploit any gap in your ductwork, and attic flex collars are a common entry point. The squirrels don’t live in your ducts, they cache food near warm, sheltered spaces. Newer developments without mature trees rarely have this problem. We seal with mastic and mesh, then recommend collar reinforcement if the gap was large enough to admit debris.
We were called to a ranch-style home off Cirby Ranch where the homeowner’s supply registers were spitting out bits of dried oak leaf and fine grey dust every time the air handler kicked on. A camera inspection showed a kinked flexible run in the attic with a torn collar, plus a rodent-chewed gap in the return that was pulling acorns and nesting debris straight off the insulation. We sealed the collar and gap with mastic and mesh, re-connected the sagging run, and the static pressure drop across the blower motor immediately improved.
In Roseville’s older oak-shaded neighborhoods, attic duct runs are routinely packed with acorns and nesting material that squirrels push through failed connections – a problem that barely exists in newer tree-less tract developments where the canopy hasn’t matured enough to attract them. This is why we always camera-inspect before quoting. The fix for a squirrel-compromised return is different from a simple collar re-seal, and pricing them the same would mean doing one job wrong or overcharging for the other. Roy Castellanos built our Roseville operation on getting that distinction right.
