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 Elk Grove
Duct sealing in Elk Grove typically runs $450 – $950 for a whole-house system, and our crews schedule most jobs within a week of your call. Ask about bundling with Elk Grove Dryer Vent Cleaning for a single visit. If you’re in Laguna West, Stonelake, or the older pocket near Elk Grove Boulevard and Bruceville, we’ve likely already worked on a house with the same truss-pinched flex duct that’s in your attic right now. Call (361) 326-5060 for a written estimate before any work starts.
We dispatch from our Sacramento scheduling office, but our techs live in and around Elk Grove. They know the difference between a 1998 Shea Home off Franklin Boulevard and a 2005 Meritage build near Laguna Springs. That matters because the ductwork problems are different, and the fix has to match the house, not a generic checklist. Our Duct Sealing team carries Rotobrush rotary systems, Nikro negative-air machines, and Guardsman foil tape and mastic on every truck. We seal what can be sealed, repair what can’t, and we photograph the before and after so you see what you paid for.
Why Hollis Air Duct Cleaning Is Elk Grove’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004. The Garrison Standard means written prices, written guarantees, and a 365-Day Done Right Promise on every job. In Elk Grove, that standard matters because too many homeowners have watched a low teaser quote balloon once the technician is inside the attic.
Our technicians are background-checked and uniformed. You know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops. When you call (361) 326-5060, you talk to a human who can schedule your Elk Grove appointment and email a confirmation with your technician’s name.
We don’t compete on the cheapest bid. We compete on the bid you can trust: one flat price per system, agreed in writing before we touch anything. If the seal fails within a year, we come back and make it right at no charge. That includes a free second visit, not a negotiation.
Local knowledge is part of the value. We know that Elk Grove’s 1990s – 2000s tract-home boom left thousands of houses with flexible foil-backed ductwork stapled to attic trusses. Those ducts are now 20 – 30 years old. The Sacramento Valley heat bakes them. The original bracing crushes them. And nearby agricultural fields and creeks send rodents into the runs. We see it weekly. That’s why Duct Sealing in Elk Grove isn’t a copy-paste job from another city.
HVAC Duct Sealing in Elk Grove
HVAC Duct Sealing in Elk Grove means closing the gaps, joints, and pinholes in your forced-air duct system so the air you paid to heat or cool actually reaches the rooms it’s supposed to. Most Elk Grove homes built between 1990 and 2010 have flexible duct runs in vented attics. The original foil-backed liner dries out, tape adhesive fails, and connections at the plenum and register boots loosen. We seal with mastic compound and foil-backed tape rated for attic temperatures, then verify airflow improvement with a static-pressure test at the air handler. A typical HVAC duct sealing job in Elk Grove runs $450 – $750 for a single-system home under 2,500 square feet. Larger homes or dual-zone systems run $750 – $950.
When Sealing Makes Sense
Sealing is the right call when your ducts are intact but leaking at joints, seams, or connections. Common signs: rooms that won’t hold temperature, dust blowing from registers, or energy bills that climbed without explanation. In Elk Grove’s 100°F+ summers, every cubic foot of cooled air lost to the attic is money you’re paying to cool fiberglass insulation. We photograph the leaks before we seal and the sealed joints after, so you see the work.
When Sealing Is Not Enough
Some ducts are too far gone. If the inner foil liner is torn, crushed flat by truss bracing, or chewed through by rodents, sealing the outside won’t fix airflow. We’ll tell you that during the inspection, show you the camera footage, and quote repair or replacement separately. No bait-and-switch. No pressure to seal something that needs cutting out.
Duct Repair in Elk Grove
Duct Repair in Elk Grove addresses the physical damage that sealing alone can’t fix: crushed flex runs, torn inner liners, rodent-chewed sections, and disconnected boots. Our techs carry replacement flex duct, insulated register boots, and Guardsman foil tape and mastic on every truck. We cut out the damaged section, source-remove debris and nesting material, install new liner, seal all joints, and verify negative pressure at the air handler before we leave. A typical duct repair in Elk Grove runs $300 – $650 for a single section or register boot replacement. Extensive re-runs or multiple crushed lines in a 2,400 sq ft home can reach $800 – $1,400.
Crushed Flex Duct From Truss Bracing
Elk Grove’s 1990s – 2000s tract-home flex duct was stapled directly to truss bracing in vented attics. In Laguna West and Stonelake we regularly find the inner foil liner crushed against the same trusses that hold the roof up, which seals off airflow long before the duct ever tears. We open the crushed section, rebuild the airway, and rehang the duct with proper support straps so it doesn’t happen again.
Rodent Damage Near Creeks and Fields
Elk Grove’s agricultural edges and creek corridors send roof rats and field mice into attic ductwork. They chew the foil liner for nesting material and leave debris that blows into your living space. We remove the nest, cut out chewed sections, and seal the repair with mastic rated for attic heat. Then we show you the entry points so you can address them with a pest control specialist.
Trusted Brands We Service in Elk Grove
We stock Guardsman foil tape and mastic, Aprilaire filtration components, and Abatement Technologies negative-air accessories on our Elk Grove trucks. These aren’t hardware-store brands. Guardsman tape is rated for continuous exposure in 200°F attics. Aprilaire media filters integrate with the return plenum on most Elk Grove HVAC systems. Abatement Technologies HEPA filtration captures the fine particulate that rotary brushing knocks loose. Because we carry parts locally, most repairs don’t wait for a Sacramento supply-house run. Your job finishes in one visit, priced before we start.
Common Duct Sealing Problems We See in Elk Grove Homes
- Truss-pinched flex ducts in Laguna West attics. The original builder stapled flex runs directly to truss bracing. Twenty years of heat cycling and roof load compress the duct flat. Homeowners wonder why the back bedroom never cools. We find two supply runs pinched to half-inch slits.
- Torn inner liners filled with attic dust and insulation. The 100°F+ Sacramento Valley summers dry and crack the foil lining. The AC blower pulls attic debris into the tear. Sealing over the debris without source-removing it first means the seal fails within a season when the mastic can’t bond to dust.
- Rodent nests in runs near Laguna Creek and Stone Lake. Agricultural fields and riparian corridors border Elk Grove neighborhoods. Rats access soffits, nest in ductwork, and leave debris that contaminates the supply air. We remove the nest, repair the duct, and verify no debris remains before sealing.
- Disconnected register boots in slab-duct homes near Elk Grove Boulevard. Some 1990s builds used shallow slab chases instead of attic runs. Settlement and thermal expansion pull the boot away from the duct. Conditioned air blows into the concrete void. We reconnect and seal with mastic, then test static pressure to confirm the fix.

FAQs About Duct Sealing in Elk Grove
Most Elk Grove homes need duct sealing once every 10 – 15 years, or after any major HVAC replacement. The 1990s – 2000s tract housing stock here is hitting that window now. If your ducts were sealed more than a decade ago, the original tape and mastic have likely dried and cracked in the attic heat. Call (361) 326-5060 and we’ll inspect for free.
We charge one flat price per system, never per vent. Per-vent pricing is how some outfits quote low and invoice high. We count your supply and return runs during the free inspection, then give you a single written price for the whole system. That price doesn’t move once we start.
At a typical 2,000 sq ft Elk Grove house, we access the attic, inspect each run with a camera, remove debris from leaks, seal all plenum connections and branch joints with mastic and foil tape, rehang any sagging flex, and test static pressure at the air handler before we leave. We photograph the work and email you before-and-after images with your invoice. The job usually takes 3 – 5 hours.
No. Sealing a crushed duct just traps air that still can’t move. We cut out the crushed section, install new flex duct with proper support straps, seal the joints, and verify airflow. In Laguna West and Stonelake, this is a common fix for 2000s-era builds where original truss bracing pinched the supply runs flat.
We don’t promise same-day service. Duct sealing is a scheduled job that requires attic access, camera inspection, and several hours of careful work. We typically schedule within a week of your call. The wait is worth it: a thorough job done by the book, with a written price and a year-long guarantee. Call (361) 326-5060 to book.
