Fort Worth isn’t Dallas. The soil is different. The wind patterns are different. The houses are different. That means the way ducts fail here is different too, and we’ve learned to spot it.
Why Bellows Air Duct & Vent Co. of Texas Is Fort Worth’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Fort Worth one job at a time, starting back when most of these postwar ranch homes were still relatively new. Homeowners in the 76111, 76112, 76113, and 76114 ZIP codes know our vans. They know our uniformed technicians show up when we say we will, and they know we don’t leave until the camera inspection proves the work is right.
Our reviews from Fort Worth customers consistently mention the same things: we answer the phone, we show the price before we start, and we come back if something’s not right. No paperwork. No arguing. That’s the 90-Day Done Right Promise, and it’s stamped on every job we do.
Response time to Fort Worth is typically same-day or next-day. We understand that when your ducts are pulling 100°F attic air into your living room in July, or when a dust storm has just blown through and your system is circulating grit through every room, you don’t want to wait. Our office routes technicians efficiently through River Oaks, Forest Hill, and the North Fort Worth corridors.
Here’s what separates us from the discount operators: we camera-inspect every duct system before we quote and after we finish. You see what we see. The price we give on the phone is the price on the invoice. Wade Kellerman, our owner, set that standard in 1984 and we haven’t wavered from it.
Our Duct Repair & Sealing Services in Fort Worth
Duct Sealing
Fort Worth’s combination of expansive clay soil and heavy HVAC use makes duct sealing one of our most called-for services. When slab foundations heave and settle, they pull duct joints apart at the seams. We seal these gaps properly - not with tape that will fail in the next heat wave, but with mastic sealant rated for the temperature swings and dust load this city sees. A typical duct sealing job in Fort Worth runs $280-$480 for a standard ranch home.

Flex Duct Repair
Flex duct is common in Fort Worth’s 1950s-1970s housing stock, and it’s where we see the most dramatic failures. Seasonal foundation movement tears the collar connections loose, especially in crawl-space-free slabs throughout Stop Six, Polytechnic Heights, and North Fort Worth. We replace damaged flex runs, install stainless steel collar clamps that can tolerate future shifting, and seal everything with mastic. Flex duct repair in Fort Worth typically costs $180-$340 per run.

Metal Duct Repair
Older homes in the Cultural District and near TCU - the 1920s-1940s builds - sometimes still have original galvanized steel trunk lines. These can corrode at the seams, separate at joints, or develop holes from decades of vibration. We patch, reseal, or replace sections as needed, always matching the gauge and configuration of the existing system. Metal duct repair in Fort Worth generally runs $220-$450 depending on accessibility and extent of damage.

Duct Insulation
With Fort Worth regularly seeing 60-70 days above 100°F in peak years, uninsulated or degraded duct insulation in the attic is costing you money every minute the AC runs. We install fresh fiberglass wrap or closed-cell insulation where appropriate, sealed at every seam. Attic duct insulation in Fort Worth typically runs $350-$650 for a complete system.

Trusted Brands We Service in Fort Worth
We carry Rotobrush and Nikro equipment on every truck - the same brands serious HVAC contractors specify for duct access and cleaning prep. For sealing materials, we use professional-grade mastic compounds and Honeywell- and Aprilaire-compatible components where integration with existing air quality systems is needed. We stock common collar sizes, flex diameters, and sealant quantities specifically for the Fort Worth market, so we’re not ordering parts while your house sits open. Most jobs finish in one visit.
Common Duct Repair & Sealing Problems We See in Fort Worth Homes
- Seasonal slab heave tears flex-duct collars loose. The Blackland Prairie expansive clay beneath Fort Worth’s postwar ranch homes swells when wet and shrinks when dry. This constant movement pulls duct connections apart, especially in crawl-space-free slabs. We find these gaps routinely in homes from the 1950s through the 1970s.
- Delaminated fiberglass duct board sheds insulation fibers into living spaces. Original duct board from the 1940s-1970s has reached the end of its useful life in many Fort Worth homes. The interior lining breaks down and blows through registers, creating a fine gray dust that settles on furniture and triggers respiratory irritation.
- Dust storm loading contaminates mastic surfaces before sealing. In the Windy Gap corridor and across western Fort Worth, West Texas dust storms load duct interiors heavily. If a technician seals over this contamination, the mastic won’t bond properly. We clean before we seal - always.
- Gravity-furnace trunk systems in prewar homes leak at every joint. The older homes near TCU and in the Cultural District still contain original trunk-and-branch ductwork designed for coal or early gas gravity furnaces. These systems were never intended for forced air and leak extensively at unsealed joints.

FAQs - Duct Repair & Sealing in Fort Worth
Most Fort Worth homes benefit from a professional duct inspection every 3-5 years, with sealing as needed. The expansive clay soil here means new gaps can develop after any significant drought or rainy period. If you notice uneven cooling, rising energy bills, or more dust after a season of heavy rain followed by dry heat, it’s time to call. We’ll camera-inspect and show you exactly what’s changed. Call (866) 347-2063 to schedule - estimates are free.
Yes, proper sealing significantly reduces the dust entering your duct system, but only if the sealing is done after thorough cleaning. Fort Worth’s location at the western entry of the Metroplex means ducts here load with particulate faster than in Dallas or Arlington. Sealing gaps prevents unfiltered attic and wall cavity air from entering, but sealing over contaminated surfaces traps that dust inside. We clean first, seal second, and prove it with camera footage. Call (866) 347-2063 for an assessment.
Yes, we repair and seal these systems in the 1920s-1940s homes near TCU and in the Cultural District. Original gravity-furnace ductwork was built for natural convection, not forced air, so the joints and seams were never designed to handle the pressure of a modern blower. We reinforce weak points, seal all accessible joints with mastic, and advise when section replacement makes more sense than repair. Call (866) 347-2063 to discuss your specific system.
We use professional-grade mastic sealants rated for the temperature extremes and dust exposure common in Fort Worth, along with stainless steel collar clamps and hardware from Rotobrush and Nikro for access and prep work. For homes with integrated air quality systems, we use Honeywell- and Aprilaire-compatible components. Every material is chosen for durability in this specific climate, not just generic performance. Call (866) 347-2063 for specifics on your job.
Most North Texas home warranties cover HVAC equipment failure but exclude ductwork as “maintenance” or “pre-existing condition” unless the damage resulted from a covered peril. We provide detailed written estimates and photo documentation that many homeowners have successfully used to support warranty claims, but we do not guarantee warranty approval. Our Free Second Opinion on Any Written Estimate can help you compare what your warranty company is offering versus what the repair actually requires. Call (866) 347-2063 to review your situation.
