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.

Duct sealing in Haltom City typically runs $850 – $2,400 for a whole-home system, with most jobs completed in a single day after inspection. Our crews serve Haltom City from the Dallas-Fort Worth metro office, carrying Rotobrush rotary systems and Guardsman mastic rated for the 140°F attic temperatures this city’s older homes endure. Call (361) 326-5060 for a free written estimate before any work starts.
We’ve worked in Haltom City long enough to know the difference between a simple seal job and one complicated by storm water, industrial dust, or heat-cooked flexible duct. Homes near Diamond Oaks, along Midway Road, and throughout the neighborhoods between NE 28th Street and Highway 377 present conditions you won’t find in Fort Worth or North Richland Hills. The rigid metal trunks in these 1940s – 1970s houses have seen decades of expansion and contraction. The flexible branch lines running through attics that bake to 140°F in July have insulation that crumbles when touched. And the industrial belt along NE 28th Street deposits metal fabrication dust that standard sealing would simply trap inside.
That’s why our Duct Sealing team doesn’t quote over the phone. We inspect with cameras, document what we find, and give you a written price before any mastic goes on.
Why Hollis Air Duct Cleaning Is Haltom City’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. Our Haltom City customers know our technicians arrive uniformed, background-checked, and inside the quoted window. No voicemail loops, no callback queues. Phones are answered by a live person 24 hours a day, 7 days a week.
What separates us in Haltom City is documentation. When storm water enters ductwork, insurers demand proof of what was damaged versus what could be cleaned and sealed. We provide before/after photos, moisture readings at each register, and written findings. The adjuster gets what they need. You get a sealed system that won’t fail next season.
Every job carries our 365-Day Done Right Promise in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit. No negotiation. No “call the office and we’ll see.” It’s on the invoice when we leave.
Roy Castellanos built this standard into every Hollis location. Each is independently owned and operated, but all follow The Garrison Code: arrive inside the window, price in writing, complete the job by the book, leave the site clean.
Duct Insulation in Haltom City
Duct Insulation in Haltom City addresses the specific damage done by attics that routinely exceed 140°F in summer and the humidity that follows every thunderstorm. In this city’s 1940s – 1970s housing stock, original fiberglass wrap around rigid metal trunks has often degraded to the point where it holds moisture rather than repelling it. We remove compromised insulation, seal the metal beneath with Guardsman mastic and mesh, then install new wrap rated for the temperature swings these attics produce. A typical Duct Insulation project in Haltom City runs $1,200 – $2,800 depending on linear footage and accessibility.
When Insulation Must Be Replaced Before Sealing
Heat-embrittled flexible duct insulation cannot be sealed over. The mastic adheres poorly, and trapped moisture breeds mold. Our camera inspection identifies which runs are salvageable and which need replacement. We document this for your records and for any insurance claim.
Material Selection for Local Conditions
We specify insulation with higher R-values and vapor barriers than code minimum because Haltom City’s combination of attic heat and humidity punishes lesser materials. This isn’t upselling. It’s matching the product to the environment.
HVAC Duct Sealing in Haltom City
HVAC Duct Sealing in Haltom City starts with understanding that this city’s duct systems have breathed industrial air for decades. The fabrication shops along NE 28th Street and Midway Road produce metal particles that standard residential filters don’t catch. These particles embed in duct sealant, accelerate corrosion, and create leak paths that foil tape can’t permanently close. Our HVAC Duct Sealing process uses mechanical cleaning first, then Guardsman mastic applied with proper mesh reinforcement on rigid metal, followed by negative-air verification that the seal holds under pressure. Typical HVAC Duct Sealing in Haltom City costs $850 – $2,400 for a complete system.
Storm Water Changes the Sequence
After water intrusion, sealing without inspection traps moisture. We camera every branch, replace saturated flex runs, and only then seal the remaining system. Our field documentation includes moisture percentage readings and photo timestamps.
Metal Duct Expansion and Contraction
Haltom City’s temperature swings, 140°F attics against 72°F conditioned air, cause rigid metal to expand and contract daily. Standard foil tape fails within a season. We use mastic rated for thermal cycling, applied to clean metal with proper prep.
Trusted Brands We Service in Haltom City
Our trucks stock Guardsman mastic and mesh, Aprilaire filtration components, and Abatement Technologies negative-air equipment. For Haltom City homeowners, this means no waiting on parts while your system stays open. When we find a compromised Aprilaire media filter during a sealing job, we replace it same day. When a duct run needs mechanical cleaning before sealing, the Rotobrush rotary system is on the truck, not back at a warehouse. We don’t quote equipment we don’t carry, and we don’t schedule work we can’t finish in one visit unless the scope requires it.
Common Duct Sealing Problems We See in Haltom City Homes
- Sealing over heat-degraded flexible duct insulation in 140°F attics without replacing the compromised run. The new mastic looks fine, but trapped moisture and mold behind it re-emerges as odor and airflow loss within months. We replace damaged flex first, always.
- Using standard foil tape on rigid metal supply and return ducts that expand and contract in Haltom City’s temperature swings. The tape cracks, the leak returns, and the homeowner pays twice. We use mastic rated for thermal cycling, properly reinforced.
- Missing a water-intruded branch from a storm-damaged fresh-air intake because the crew skipped camera inspection. Saturated insulation re-wets the entire system after sealing, destroying the work and creating a mold liability. We camera every branch, document moisture, and replace before we seal.
- Applying sealant over industrial dust from NE 28th Street fabrication shops without mechanical cleaning first. The dust prevents adhesion, and metal particles continue corroding the duct. Our rotary brush system cleans before we seal.
Pricing for Duct Sealing in Haltom City, TX

FAQs About Duct Sealing in Haltom City
Camera inspection and moisture readings determine the answer. If water reached the insulation inside a flex run, we replace that section; saturated insulation cannot be cleaned and will mold if sealed over. Rigid metal trunks can usually be cleaned, dried, and sealed if corrosion hasn’t perforated them. Call (361) 326-5060 and we’ll inspect with documentation for your insurer.
Yes. We provide timestamped moisture readings at each register, before/after photos, written scope of work, and itemized replacement versus cleaning recommendations. Adjusters in Tarrant County recognize this format. Our field vignette from Diamond Oaks: a 1950s ranch with storm water through a failed fresh-air intake, 12 feet of saturated flex replaced, remaining trunk sealed with Guardsman mastic, negative pressure cleaning and HEPA filtration completed, musty odor cleared, insurer accepted our moisture documentation.
Often yes, if the metal is intact. These older rigid systems are more durable than modern flex in many ways, but the original sealant has likely baked and cracked in decades of 140°F attic heat. We remove old sealant mechanically, inspect for corrosion, and reseal with modern mastic rated for thermal cycling. Replacement is only necessary where water has perforated the metal or where access makes repair impractical.
Industrial dust combines with storm moisture to form a gritty paste that prevents sealant adhesion and accelerates corrosion. Sealing over it traps both problems. We rotary brush clean with Rotobrush equipment before applying Guardsman mastic. This step is non-negotiable in Haltom City’s industrial zone; skip it and the seal fails prematurely.
We work year-round. Our technicians are equipped for attic work in peak summer, and mastic curing is actually faster in warm conditions. The 140°F ambient you worry about is precisely why your original sealant failed; modern products handle it fine when properly applied. Waiting risks further energy loss and moisture intrusion from ongoing storms.
