Fast, Reliable Duct Repair & Sealing Across Kennedale
Duct repair and sealing in Kennedale typically costs $180-$650 depending on the scope, and most jobs are completed in a single visit with upfront pricing confirmed before we start.

We’ve worked in Kennedale since the 1980s, back when much of the 76060 ZIP was still open pasture and the first subdivisions were going in along Little School Road and Kennedale Parkway. We know the builder-grade flex duct systems that went into those homes, and we know what Tarrant County’s black clay soil and the diesel particulate off US-287 have done to them since. Our technicians are usually in Kennedale within the hour when you call (866) 347-2063, and we don’t charge to look and tell you what’s wrong.
Why Bellows Air Duct & Vent Co. of Texas Is Kennedale’s Preferred Duct Repair & Sealing Company

Our Duct Repair & Sealing Services in Kennedale
Duct Sealing with Mastic Sealant
Kennedale’s combination of diesel soot from the 287 corridor and Tarrant County clay dust creates a unique challenge for duct sealing. Mastic sealant is the only product we trust for lasting results here, because it fills gaps and joints with a flexible, permanent bond that tape simply cannot match. We apply mastic by hand at every joint, collar, and penetration after properly cleaning the surface - critical in Kennedale, where soot residue left underneath causes adhesion failure within months. A typical mastic sealing job in Kennedale runs $280-$450 for a single system.
Flex Duct Repair
The flex duct installed in Kennedale’s 1980s-2000s homes was never meant to last 30 years in 140°F attics. We see sagging, torn outer jackets, and collapsed inner cores throughout the 76060 ZIP, especially where seasonal foundation movement has stressed connections at registers. Our flex duct repair replaces damaged sections with new R-8 insulated flex duct, properly supported and sealed, rather than patching with tape that fails in the heat. Most flex duct repairs in Kennedale fall between $180-$340 per section.
Metal Duct Repair
Older Kennedale homes and some custom builds near the original town center have galvanized metal ductwork that corrodes at seams and collects condensation in our humid North Texas summers. We repair metal ducts with proper sheet metal patches, sealant, and structural support - no duct tape, ever. Metal duct repair in Kennedale typically ranges $320-$580 depending on accessibility and extent of corrosion.
Duct Insulation
Unconditioned attics in Kennedale regularly exceed 140°F from June through September, cooking the air inside poorly insulated ducts before it ever reaches your vents. We install R-8 insulation on repaired or replaced duct sections, and we can upgrade existing under-insulated runs throughout your system. Proper insulation pays for itself in reduced runtime and more even temperatures. Duct insulation work in Kennedale generally runs $400-$650 for a complete system upgrade.

Trusted Brands We Service in Kennedale
We carry Rotobrush and Nikro equipment for thorough duct cleaning and preparation before sealing, and we stock Honeywell and Aprilaire filtration upgrades for Kennedale homes dealing with heavy particulate loads. Our technicians arrive with the parts to complete most jobs without a return trip, because we know you don’t want to take another day off work. When we recommend a Honeywell media filter for a home near the 287 corridor, it’s because we’ve measured the difference it makes in reducing that black soot buildup between service calls.
Common Duct Repair & Sealing Problems We See in Kennedale Homes
- Builder-grade flex ducts in 2000s master-planned homes often sag and tear at joints within 5-10 years, especially when attics exceed 140°F, causing airflow loss and debris entry. We find this pattern repeatedly in subdivisions off Kennedale Parkway where original ductwork has never been touched.
- Duct sealing on older homes near SH-287 fails quickly if mastic is applied over diesel soot residue without first cleaning the surface, leading to adhesion failure and recurring leaks. This is why we camera-inspect and clean before we seal - every time.
- Slab foundation movement from Tarrant County clay soils can slip or detach flex duct connections at registers, leaving gaps that bypass the filter and draw in attic contaminants. We check every register connection during our inspection.
- Black soot-like coating inside ducts near the industrial edges of 287 - a mix of diesel particulate and clay dust that standard brushing alone won’t address and that returns quickly if duct sealing and filtration upgrades aren’t done at the same visit.

FAQs - Duct Repair & Sealing in Kennedale
The fine particulate from US-287/SH-287 travels farther than most homeowners expect, and Kennedale’s prevailing winds carry diesel soot and road dust well into residential neighborhoods. That black residue mixes with Tarrant County’s red clay dust in your attic, then gets pulled into your duct system through leaks and gaps. We address this with thorough cleaning before sealing, mastic application at every joint, and upgraded filtration to catch what slips through. Call (866) 347-2063 for a camera inspection - estimates are free.
Tarrant County’s expansive black clay soils shift seasonally, causing slab foundations to move and flex duct connections at registers to slip, crimp, or detach completely. A standard sealing job that ignores these mechanical stresses will fail when the next dry spell hits. We inspect every register connection for physical displacement, repair or replace damaged sections, and seal with materials that tolerate movement without cracking. Call (866) 347-2063 to schedule - we’ll show you exactly what’s happening in your attic.
Yes, if the temperature imbalance is caused by duct leakage - which it usually is in Kennedale’s builder-grade homes from that era. We typically find 20-30% airflow loss through gaps and disconnected joints in 2000s tract homes, especially where flex duct has sagged in hot attics. Sealing restores designed airflow to every room. If your problem is duct sizing or balancing, we’ll tell you that too before we do any work. Call (866) 347-2063 for an honest assessment.
Sealed ducts add measurable efficiency that shows up on utility bills and inspection reports, and in Kennedale’s market, buyers increasingly ask about HVAC condition and energy costs. More immediately, you’ll stop overpaying for heating and cooling every month you still live there. Our typical Kennedale customer sees payback in 2-3 years through reduced utility bills alone. Call (866) 347-2063 to run the numbers for your home - estimates are free.
Every duct repair and sealing job in Kennedale carries our 90-Day Done Right Promise in writing: if the work is not right, we return at no charge with no paperwork required.

We’ve honored this promise for over 42 years because we intend to still be here when you need us again. Call (866) 347-2063 with questions - a live person answers 24/7.
