Fast, Reliable Duct Sealing Across Sansom Park
Duct sealing in Sansom Park typically costs $850 to $2,400 depending on the size of the home and how much of the ductwork runs through crawlspaces and attics. Most jobs take one full day. If you’re in a pre-1960 home near Silver Creek or along the hillier streets off River Oaks Boulevard, your ducts likely have leaks at the joints and connections that have been there for decades. Call (682) 255-2572 for a written quote before any work starts.
Roy Castellanos and the Hollis Air Duct Fort Worth crew know these houses. We’ve opened enough crawlspaces in Sansom Park to know exactly what’s waiting down there: original metal ductwork, flood silt from Silver Creek, post oak pollen packed into every seam, and joints that have been pulling attic air and dust into the supply stream since the Eisenhower administration. That’s what we fix.
Why Hollis Air Duct Fort Worth Is Sansom Park’s Preferred Duct Sealing Company
We’ve built our reputation in Sansom Park on showing up when we said we would and pricing the job before any work begins.

Our technicians are background-checked and uniformed, so when a Hollis van pulls up to a house off Azle Avenue or Jacksboro Highway, you know exactly who’s walking in. We call before we arrive. We arrive inside the window. And we leave the site cleaner than we found it. Those aren’t promises we make lightly; they’re how every Sansom Park job runs.
Roy Castellanos leads each project personally, and every duct sealing job carries the 365-Day Done Right Promise in writing. If a sealed joint fails within a year, we come back and make it right at no charge. No renegotiation, no second invoice. That’s the Garrison Standard, and it applies to every home we service in Sansom Park.
Styles & brands we work with
Duct Sealing Services in Sansom Park
Duct Sealing Services in Sansom Park focus on closing the air leaks that bleed conditioned air into attics, crawlspaces, and wall cavities before it ever reaches your registers. In older homes with original sheet-metal ducts, the loss is often 20 to 30 percent of everything your AC produces. That’s air you paid to cool, escaping into spaces you never use. Our Duct Sealing crew locates those leaks with a digital manometer, seals them with mastic we apply by hand at every joint and seam, and then verifies airflow at each register before we pack up.
A typical duct sealing job in Sansom Park runs $850 to $1,900 for a single-story home with accessible ductwork. If the runs pass through tight crawlspaces or uninsulated attics that require extra time and protective measures, the range rises toward $2,400. We write the number down before we start. It doesn’t move.
Crawlspace Sealing
Most Sansom Park homes built before 1970 sit on pier-and-beam foundations with ductwork running through the crawlspace. We seal supply and return joints with mastic that stays flexible through the temperature swings those spaces see between summer and winter. Then we check airflow at each register to confirm the system is balanced.
Attic Duct Sealing
For homes with attic-mounted air handlers, we seal the plenum connections and every branch line. In Sansom Park’s hot summers, unsealed attic ducts pull in fiberglass and dust with every cycle. Sealing them changes what you breathe and what you pay to cool.

Duct Insulation in Sansom Park
Duct Insulation in Sansom Park works hand in hand with sealing. Sealed joints still sweat in the summer when cool air moves through ductwork sitting in a 130-degree attic. That condensation attracts dust, grows mold on the outside of the metal, and eventually rusts through the joints you just sealed. Wrapping the runs with insulation stops that cycle. For crawlspace ducts that pass through damp, flood-prone areas near Silver Creek, insulation also prevents the exterior corrosion that comes from year-round moisture in the soil.
Duct insulation in Sansom Park typically runs $950 to $2,200 depending on how many feet of ductwork need wrapping and whether it’s in the attic, the crawlspace, or both. We use insulation rated for the temperatures those spaces actually reach, not whatever’s cheapest at the supply house.
Attic Insulation Wraps
We wrap supply trunks and branch lines with the proper R-value insulation, then seal the jacket seams so no metal is exposed to humid attic air. This keeps condensation off your ducts through the worst of a Sansom Park August.
Crawlspace Insulation
In crawlspaces, we add a vapor barrier where needed and wrap ducts with insulation that resists moisture wicking from the soil. Flood silt from Silver Creek holds water for weeks after heavy rain. Your ductwork shouldn’t soak in that.
Trusted Brands We Service in Sansom Park
We work on every major brand of HVAC equipment found in Sansom Park homes, and we stock common parts locally so we’re not waiting on a warehouse in another state when your job needs a fitting or a collar. Our sealing and insulation work integrates with systems from Trane, Carrier, Lennox, Goodman, Rheem, and York, plus older units from builders who installed whatever was on the truck in 1962. For air quality, we carry filtration products from Honeywell, Aprilaire, and Guardsman, and our negative-air machines from Nikro and rotary brush systems from Rotobrush are the same commercial-grade tools used on large commercial jobs. We explain what each piece does and why it matters for your home, in plain English.
Common Duct Sealing Problems We See in Sansom Park Homes
- Silver Creek flood silt in crawlspace ducts. Homes near the creek see silt deposits that wick moisture into duct joints, corroding the metal and opening leaks. Sealing here requires cleaning the duct surfaces first, then applying mastic that bonds despite residual dampness.
- Original metal ducts from the 1930s to 1970s. These systems were built with slip-fit joints that loosen as the house settles. We find gaps at nearly every connection in older Sansom Park homes, and each gap pulls air from whatever surrounds it.
- Post oak and cedar pollen infiltration. The dense tree cover on Sansom Park’s hillsides puts heavy pollen loads into attic and crawlspace air. Unsealed return ducts pull that pollen directly into your living space, coating registers and aggravating allergies.
- Shared dryer vent stacks in multi-unit buildings. In apartments and older duplexes, sealing only one unit’s portion of a shared stack doesn’t fix the problem. Lint continues to build in the common pathway, causing backpressure that can blow out at a neighbor’s connection.

FAQs About Duct Sealing in Sansom Park
Silver Creek flood silt wicks moisture into crawlspace duct joints, which corrodes the metal and causes the mastic to fail at the lowest points of the system. In homes near the creek, we clean the duct surfaces before sealing and recommend insulation or a vapor barrier to keep standing moisture away from the sealed joints. If your home has had water in the crawlspace, call us for an assessment at (682) 255-2572.
Yes, in most cases. Original metal ductwork from the 1950s is often structurally sound even when the joints have loosened. We seal every connection with mastic and, where the metal has rusted through, we patch or sleeve the section rather than replacing the entire run. Full replacement is rarely necessary unless the ducts have collapsed or are too corroded to hold a seal. We’ll show you what’s in the crawlspace and explain what the job needs before we touch anything.
We can seal your unit’s HVAC ducts, but shared dryer vent stacks need a different approach. Sealing one unit’s portion of a shared stack leaves the common lint pathway restricted, which causes backpressure and eventual blowout at a neighbor’s connection. For these buildings, the stack itself needs to be cleaned and sealed as a system. If you’re in a Sansom Park apartment or duplex with a shared stack, call us and we’ll assess what’s actually going on before recommending a fix.
Yes, significantly. Post oak and cedar pollen enters your home through the return side of the system, where unsealed joints in attics and crawlspaces pull in outside air. Sealing those joints stops the pollen from being drawn into the ductwork in the first place. Homes with heavy tree cover, like most of Sansom Park’s hillside streets, see the biggest difference after sealing.
One full day, usually. A typical single-story Sansom Park home with crawlspace ductwork takes 6 to 9 hours to seal properly, including setup, sealing each joint, insulation where needed, and airflow verification at every register. Larger homes or systems with extensive corrosion may run into a second day. We’ll tell you the timeline before we start, and it’s part of the written quote.
