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 White House
Duct sealing in White House, TN typically runs $450 – $1,200 for a whole-home system depending on access and how much flex duct needs rehanging, and most jobs are scheduled within a few business days with a written price locked in before we start. We’re the Duct Sealing crew for Hollis Air Duct Cleaning, and we know the homes here, from the subdivisions off Highway 76 to the properties stretching toward Portland. Scheduling and dispatch run through our Memphis office, but our trucks are on White House roads every week. If your upstairs bedrooms won’t cool or your power bill keeps climbing, call us at (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is White House’s Preferred Duct Sealing Company
We’ve been doing this since 2004 as part of the Garrison Partners family, and that track record matters in a market where too many outfits advertise a low price then rewrite the invoice once they’re in your attic. Our technicians are background-checked and uniformed, and we follow The Garrison Code on every job: arrive inside the window, price in writing, work by the book, leave the site clean. That standard is backed by our 365-Day Done Right Promise. If the sealing fails within a year, we come back and make it right at no charge, including a free second visit.
White House homeowners call us because we understand what we’re looking at. The 2000s-2010s subdivision builds here, mostly two-story and ranch brick-front homes on slab foundations off Pleasant View Road and the I-65 corridor, use builder-grade flex duct with long attic runs. We see the same floor plans repeated across neighborhoods, so we know where the takeoffs sag, where the returns get starved, and which joints are prone to tear. That local pattern recognition saves time and gets the fix right.

Air Duct Sealing in White House
Air Duct Sealing in White House means finding every leak path in your duct system, sealing joints and connections with mastic or metal-backed tape, and rehanging any flex duct that has sagged or torn away from its takeoff. Most homes here need this work every 10 to 15 years, though the heavy pollen load from surrounding farmland and cedar stands can push that interval shorter if you’ve skipped cleanings. A typical whole-home sealing job in White House runs $450 – $1,200. We price by the system, not by the vent, and the number is written down before we touch anything.
When Sealing Makes Sense
Call us when rooms on the same thermostat read different temperatures, when your HVAC runs constantly but never catches up, or when your summer power bill spikes without explanation. In White House’s humid subtropical climate, the system runs year-round, so leaks never get a season off to stay small.
What We Check First
We start with a camera inspection of the attic runs. In White House subdivisions, we routinely find crushed flex at takeoffs and single hallway returns trying to serve three bedrooms through a shared trunk. Sealing without fixing those mechanical problems just traps the leak downstream.
Duct Sealing Services in White House
Duct Sealing Services in White House cover the full repair of your supply and return ductwork, from sealing accessible joints with professional-grade mastic to replacing damaged flex sections and rebalancing airflow between rooms. Because White House’s housing stock is dominated by 5-to-20-year-old flex-duct systems in slab-on-grade subdivisions, our sealing work here focuses as much on rehanging and reconnecting sagging flex as it does on sealing joints. A typical repair runs $450 – $1,200 depending on how many runs need attention and whether we need to access tight attic spaces. Every job gets a written price upfront and falls under our 365-Day Done Right Promise.
Flex Duct Rehanging and Repair
Builder-grade flex in these subdivisions pulls away from takeoffs over time, especially in the long, hot attic runs common off Highway 76. We rehang with proper strapping, reconnect at the collar, then seal. Skip the rehang and you’re sealing around a leak that will reopen.
Return Air Balancing
That single oversized hallway return serving multiple upstairs bedrooms is a design flaw we see repeatedly in White House floor plans. We measure airflow at each grille and adjust dampers or add return capacity so sealing doesn’t starve the rooms that were already struggling.

Trusted Brands We Service in White House
We carry professional-grade equipment and materials on every truck: Rotobrush rotary brush systems for pre-sealing cleaning, Aprilaire and Honeywell filtration products, and sealing supplies from Abatement Technologies and Guardsman. For White House homeowners, that means we don’t need to order parts and make you wait. Most sealing jobs are completed in a single visit because the right materials are already on the van. If your system uses a specific filtration brand or we find a component that needs replacement during the job, we stock the common sizes and models that match what’s installed in local subdivision builds.
Common Duct Sealing Problems We See in White House Homes
- Crushed or torn flex at takeoffs. The builder-grade flex duct in 2000s-2010s White House subdivisions sags off its supports after 5 – 20 years of attic heat, especially in the long runs above slab-on-grade homes off I-65. The tear is often hidden above the insulation, so the homeowner only feels the symptom: a hot room that never balances.
- Single hallway returns overloaded. Upstairs systems in newer White House subdivisions frequently use one oversized return grille in the hallway to pull air from three bedrooms through a shared trunk. That return chokes under the load, and sealing the wrong duct run can make the starvation worse, not better.
- Pollen and biological growth trapped behind new seals. Heavy spring pollen from White House’s surrounding farmland and cedar-juniper stands coats duct interiors. Sealing dirty ducts without cleaning first locks that load inside, where humidity feeds growth year-round.
- Outbuilding and shop systems neglected. Rural properties around White House often have detached shops or outbuildings with flex duct run from the main house or a separate package unit. These systems see more dust from unpaved drives, longer flex runs with more sag points, and wood-heat particulate if the shop has a stove. They need sealing and cleaning on a shorter interval than the main house.
Pricing for Duct Sealing in White House, TN
A typical whole-home duct sealing job in White House runs $450 – $1,200. Smaller ranch homes with accessible attics and minimal flex damage fall at the lower end. Two-story subdivisions off Pleasant View Road or Highway 76 with multiple crushed runs, rehanging needs, and return balancing work push toward the higher end. We do not price by the vent. We price by the system, agreed in writing before any work starts, and that number does not move at the door.
What affects your specific cost: how many flex runs need rehanging or replacement, whether we need to add return capacity to fix an overloaded hallway return, attic access difficulty, and whether the ducts need cleaning before sealing. We always recommend cleaning before sealing on White House homes because of the pollen load; trapping dirty air behind a tight seal is a mistake we won’t make. Call (361) 326-5060 for a free estimate. We’ll inspect the system, explain what we found, and give you a written price you can take to another company if you want.

FAQs About Duct Sealing in White House
Every 10 to 15 years for sealing, and every 3 to 5 years for cleaning, though the heavy pollen and dust load from surrounding farmland and unpaved rural roads can shorten that interval. If you heat with wood or have a shop system, check annually. Call (361) 326-5060 and we’ll tell you what your specific system needs.
Because sealing the joints without fixing the underlying flex duct failure leaves the leak path open. In White House subdivisions, we routinely find torn flex sagging off takeoffs into the attic and single hallway returns trying to serve three bedrooms. We seal the takeoffs and trunk joints, rehang and reconnect the crushed flex, and rebalance the returns so upper rooms finally cool evenly.
Yes. The humid subtropical climate and heavy spring pollen from farmland and cedar stands mean ducts here collect more biological material than drier markets. We always clean before sealing on White House jobs. Sealing dirty ducts traps pollen and growth behind the seal, which is worse than the leak you started with.
Yes. Rural properties around White House often have shop systems with longer flex runs, more dust exposure from unpaved drives, and wood-heat particulate. These systems need more frequent attention and often require shorter sealing intervals. We inspect, clean, and seal them the same way we do the main house, with the same written price upfront.
We follow The Garrison Standard on every job: arrive inside the quoted window, price in writing before work starts, complete the job by the book, and leave the site clean. Technicians follow The Garrison Code for conduct in your home. Every repair is covered by our 365-Day Done Right Promise in writing.
