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 Kennedale
We dispatch to Kennedale from our Dallas-Fort Worth office, and most properties inside city limits are inside our standard service window. If you’re seeing dust blow from registers, rooms that won’t hold temperature, or a blower motor that runs longer than it should, your ductwork is likely leaking conditioned air into the attic or pulling unfiltered air back in. Call us at (361) 326-5060 for a free inspection and written estimate. We’ll show you exactly where the leaks are before we quote a dollar.
Why Hollis Air Duct Cleaning Is Kennedale’s Preferred Duct Sealing Company
We’ve been sealing ducts in Tarrant County since 2004, and Kennedale’s mix of post-war ranch homes and rural properties presents problems that newer suburban construction simply doesn’t. Our Duct Sealing in Kennedale crew knows the difference between a 1960s sheet-metal trunk with asbestos-wrap remnants and a 1990s flex system that’s been chewed by roof rats after a freeze.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing before touching anything, finish by the book, leave the site clean. Every repair carries our 365-Day Done Right Promise. If the seal fails or the leak returns within a year, we come back at no charge. That includes a free second visit, not a negotiation.

Air Duct Sealing in Kennedale
Air Duct Sealing in Kennedale means finding and closing every gap, joint separation, and puncture in your supply and return ductwork so the air you paid to heat or cool actually reaches the rooms it’s supposed to. In Kennedale’s housing stock, the leaks are rarely dramatic blowouts. They’re cumulative: a separated flex joint here, a rusted sheet-metal seam there, a trunk line that settled away from the plenum after forty summers in a 140-degree attic. Added up, a typical Kennedale ranch home loses 20 – 30% of its conditioned air to the attic before it ever hits the register.
How We Find the Leaks
We start with a visual camera inspection of the accessible trunk and branch lines, then pressurize the system and use smoke pencils or theatrical fog to locate the gaps you can’t see from the attic hatch. Our techs mark every leak on a diagram you keep. No guesswork, no “trust us, it’s bad.”
What the Sealing Process Looks Like
We seal sheet-metal seams with mastic and fiberglass mesh, reattach separated flex runs with proper collars and straps, and replace crushed or kinked branch lines. For older galvanized trunks with pinhole corrosion common in Kennedale’s 1950s – 1970s homes, we may recommend partial replacement alongside sealing. The price is written down before any work starts.
Duct Sealing Services in Kennedale
Duct Sealing Services in Kennedale cover the full scope of what it takes to restore a leaking system to code-compliant performance. That includes supply trunk sealing, return air chase repair, flex run replacement, plenum reattachment, and re-balancing dampers so every room gets designed airflow. We also inspect and seal the air handler cabinet itself, a common bypass point for attic dust in older systems.
Rural Properties and Outbuilding Systems
Kennedale’s unpaved roads and open land mean duct systems here load with fine red clay dust and agricultural pollen at a rate that urban Fort Worth or Mansfield systems never see, so the realistic sealing interval for a rural Kennedale property is 2 – 3 years versus 5 – 7 in the city – and outbuilding or shop systems often need annual service. We were out on a rural property off Dick Price Road where the homeowner’s shop system and house system both pulled from the same dusty driveway. Our tech ran a camera inspection and found the original 1970s flex runs in the attic had separated at three joints, pulling that fine clay dust straight into the return. We sealed the trunk and branch connections with mastic and mesh, then re-balanced the supply and return ducts so the air handler stopped short-cycling. The reddish tinge on the registers was gone within a week.

What We Don’t Do
We don’t spray “sealant” into ducts from a fogger and call it done. That’s not sealing; it’s coating. Our Duct Sealing team repairs the physical integrity of the system first, then verifies with a post-repair pressure check.

Trusted Brands We Service in Kennedale
Our equipment roster includes Rotobrush rotary brush systems for mechanical cleaning before sealing, Nikro negative-air machines for source removal, and filtration products from Honeywell and Guardsman. We stock common flex diameters, mastic, and collar sizes for Kennedale’s predominant duct types, so most jobs don’t wait on parts. If your system uses an older configuration – like the light-gauge 6-inch flex common in 1970s Kennedale ranches – we carry that too.
Common Duct Sealing Problems We See in Kennedale Homes
- Original light-gauge flex runs in 1950s – 1980s ranch attics separate at joints under years of thermal cycling, letting unpaved-road clay dust bypass any filter and coat the blower motor. The filter never sees that dust because it’s entering downstream of the return grille.
- Rural properties with outbuildings on separate duct systems get neglected – the shop or barn air handler pulls wood-heat ash and field pollen year-round but is rarely included in a whole-home sealing scope. We check them when we’re on site.
- Winter ice storms and freezes push rodents through attic vents into duct chases; chewed flex and gaped sheet-metal trunks in Kennedale leak at a rate that a MERV rating upgrade alone can’t fix, requiring source removal and resealing first.
- The red clay soil around Kennedale turns to sticky mud after rain, and when it dries, it becomes a fine dust that infiltrates return ducts – customers often complain of a reddish tinge on their vents after spring winds. Sealing the return chase stops this at the source.
Pricing for Duct Sealing in Kennedale, TX
A typical duct sealing job in Kennedale runs $450 – $1,200 for a standard single-story ranch home with accessible attic ductwork. Smaller partial-seal repairs start around $280. Rural properties with outbuilding systems, extensive flex replacement, or buried ductwork in slab-adjacent chases can run $1,500 – $2,400. What moves the price: how much of the system is accessible, whether we’re sealing existing duct or replacing degraded flex, and whether the air handler cabinet itself needs resealing.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons at the door. Estimates are free, and we show you the camera footage so you understand what we’re quoting.

FAQs About Duct Sealing in Kennedale
Every 2 – 3 years for sealing on rural Kennedale properties, compared to 5 – 7 years in denser urban markets. The unpaved-road dust loading and pollen exposure here degrades joints and penetrates seams faster than city systems experience. Cleaning alone won’t fix a separated flex joint. Call (361) 326-5060 and we’ll inspect to tell you which you actually need.
It’s fine red clay dust from Kennedale’s soil infiltrating through leaks in your return ductwork, bypassing the filter entirely. The dust enters the system downstream of the filter, so upgrading your MERV rating won’t stop it. Sealing the return chase and any gaped trunk connections eliminates the source. Call (361) 326-5060 for a camera inspection.
It depends on condition. If the flex is intact but joints have separated, we can reattach and seal. If the inner liner is brittle, torn, or the insulation is saturated with condensation or rodent waste, replacement is the only durable fix. We’ll show you the camera footage and quote both options in writing. Call (361) 326-5060 for an honest assessment.
Yes. We regularly seal shop and barn systems on rural Kennedale properties, often finding they’ve never been inspected despite pulling wood-heat ash and field pollen year-round. We can scope them during the same visit as your house system. Call (361) 326-5060 to include outbuildings in your estimate.
The fine clay particles are abrasive and hygroscopic, meaning they attract moisture and form a paste on blower wheels and motor bearings. Over time this increases amp draw, shortens motor life, and reduces airflow to the point of coil freeze-up. Sealing the return ductwork stops the dust at its entry point, protecting the air handler components you can’t see. Call (361) 326-5060 for a system inspection.
