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 Wildomar
We seal ductwork in Wildomar homes where the Santa Ana winds push valley dust straight through every unsealed joint. Our crews run out of the Inland Empire office and know the tract developments from Windsong Valley to the newer builds along Clinton Keith Road. Call (361) 326-5060 and we’ll give you a written price before we touch anything.
Wildomar’s not an afterthought for us. We’ve worked the flex-duct attics here long enough to know that builder-grade foil backing fails differently in 140°F heat than it does anywhere else in Riverside County. That matters when you’re deciding who to let into your attic.
Why Hollis Air Duct Cleaning Is Wildomar’s Preferred Duct Sealing Company
We’ve been doing this since 2004, and our Duct Sealing team treats Wildomar as a core market, not a drive-by.

Our 365-Day Done Right Promise covers every seal we make: if it fails within a year, we come back at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You know who’s walking in before they arrive. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
We use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. Not hardware-store gear. The same negative-air machines and rotary brush systems commercial crews use, explained in plain terms on every job.
HVAC Duct Sealing in Wildomar
HVAC Duct Sealing in Wildomar means addressing a specific problem most homeowners don’t discover until their utility bills spike or a register starts blowing dust: the foil-backed flex duct installed in local tract homes has separated at takeoffs, wyes, and kink points in 130°F-plus attics, and foil tape alone won’t hold. We seal the full attic run, not just the visible joints at the boots. A typical whole-system sealing job in Wildomar runs $850 – $1,400 for a standard single-family home, depending on how many runs need jacket restoration and whether the plenum and air handler cabinet require sealing too.
Most Wildomar homeowners call us after noticing hot rooms, dust blowing from registers, or a sudden jump in summer cooling costs. The city’s hot inland climate means HVAC systems run nearly year-round, so every leak costs you money daily.
What We Seal Beyond the Registers
We inspect and seal plenum seams, takeoff connections, wye junctions, and the air handler cabinet itself. Stopping at the register boots leaves the real leaks open. In Wildomar’s wind corridor, that’s a partial fix that fails fast.
Mastic and Mesh for Failed Liners
Where the inner liner has torn away from the outer jacket, we apply duct sealing mastic reinforced with mesh, then seal connections with UL 181 tape rated for high-temperature attics. This restores static pressure and stops the dust discharge that blows into living spaces.
Duct Repair in Wildomar
Duct Repair in Wildomar often starts with a homeowner noticing construction debris still blowing from registers years after move-in, or a room that never cools properly despite a new AC unit. We find crushed flex duct against truss chords, torn inner liners at kink points, and disconnected boots in attics where builders prioritized speed over proper support. Repair costs in Wildomar typically range from $280 for a single run replacement to $650 for multiple damaged sections with full sealing.
The housing stock here, mostly built from the 1980s through the 2010s with heavy concentration in 2000s-era tracts, used low-cost flexible ductwork prone to failure. Rural ranchettes on the outskirts sometimes have different problems, but the valley-floor homes share common failure modes we’ve documented across hundreds of calls.
Crushed and Kinked Runs
Builders often left flex duct draped over truss chords or compressed against framing. The inner liner tears at the stress point. Foil tape over the outer jacket hides the damage but doesn’t restore airflow. We replace the damaged section and support it properly.
Construction Debris Removal
Drywall dust, wood chips, and foil-facing flakes left from construction circulate through the system until they’re removed. Sealing leaks without cleaning first traps that debris, raising static pressure and straining your blower motor.
Trusted Brands We Service in Wildomar
We stock parts and materials from Nikro, Honeywell, and Aprilaire for Wildomar jobs, which means faster turnaround and no waiting on shipped components. Our Nikro negative-air machines create proper containment during duct cleaning before we seal. Honeywell and Aprilaire filtration products integrate with sealed systems to maintain pressure balance and air quality after we’ve left. We don’t guess at compatibility. We match the material to your existing system and the specific failure we’re fixing.
Common Duct Sealing Problems We See in Wildomar Homes
- Inner liner separation in 140°F attics. Wildomar’s tract homes use foil-backed flex duct that degrades faster here than in cooler climates. The adhesive between inner liner and outer jacket releases, and the liner tears at takeoffs and wyes. Foil tape over the outside misses the real damage.
- Santa Ana wind pressurization. Strong fall winds pressurize attics along the Elsinore Valley corridor and push fine dust through unsealed plenum seams. If sealing stops at the register boots, the wind just finds another entry point and recirculates debris through your supply and return ducts.
- Construction dust trapped behind new seals. New Wildomar builds often have drywall debris and blower motor contamination from rough construction. Sealing leaks without source removal first traps that debris, increasing static pressure and reducing airflow exactly when you need cooling most.
- Kinked runs against truss chords. Builder-grade installation frequently left flex duct unsupported or crushed. The inner liner tears at the kink. Homeowners feel it as weak airflow to a single room. We replace the section and install proper supports.
Pricing for Duct Sealing in Wildomar, CA
A typical whole-system duct sealing in Wildomar runs $850 – $1,400. Single-run repairs or partial sealing start around $280. What moves the price: how many duct runs need jacket restoration, whether the plenum and air handler cabinet require sealing, and whether we need to perform source removal of construction debris before sealing.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons at the door. The price we write down is the price you pay. Estimates are free. Call (361) 326-5060 for an exact quote on your home.
Homes near Inland Valley Drive or in the Windsong Valley area, or any 2000s-era tract with original flex duct, typically fall in the middle of that range. Older homes with rigid metal ductwork may cost less if the joints simply need mastic and proper sealing tape.

FAQs About Duct Sealing in Wildomar
Yes. Wildomar’s rapid new-build growth means most homes here were finished with builder-grade flex duct and construction debris still inside the system. We routinely find drywall dust, foil-facing flakes, and kinked runs in homes less than ten years old. Call (361) 326-5060 for a free inspection and written estimate.
The Elsinore Valley trough funnels Santa Ana winds directly into residential attics, pressurizing unsealed plenum seams and takeoffs. Sealing must extend to the air handler cabinet and plenum, not just register boots, or windblown dust re-enters the system. We seal the full path.
Most Wildomar homes have attic-mounted ductwork accessible through the hatch. We work from the attic, not through drywall. In rare cases with cathedral ceilings or finished attic spaces, we discuss access options during the free estimate. The written price covers the agreed scope, whatever the access method.
We use Nikro negative-air machines for containment, Abatement Technologies HEPA filtration for debris removal, and UL 181-rated tapes and mastic compounds rated for high-temperature attic conditions. For filtration upgrades after sealing, we stock Honeywell and Aprilaire products compatible with your system.
Within the first two years, ideally before the first full summer of heavy AC use. Construction debris accelerates blower motor wear, and unsealed joints waste cooling exactly when Wildomar’s 100°F-plus days demand maximum efficiency. Early sealing also catches builder installation defects while they’re still straightforward to fix. Call (361) 326-5060 to schedule.
