Fast, Reliable Duct Repair & Sealing Across Crowley
Duct repair and sealing in Crowley, TX typically runs $180-$650 depending on whether we’re patching a single flex-duct gap or resealing an entire supply system, and most jobs are completed in a single visit. If your home was built during Crowley’s 2000-2015 building boom, the original builder-grade flex ductwork in your attic has likely endured 15-20 years of 140°F-plus heat cycles, and the mastic seals are starting to crack.

Our Duct Repair & Sealing Services in Crowley
Duct Sealing
Most Crowley homes lose 20-30% of conditioned air through gaps at the supply plenum, duct boots, and register connections. We seal with mastic and reinforced mesh, not tape that dries out in your attic. A full system reseal in Crowley typically runs $400-$650 for a single-story home, and we verify the result with a static-pressure test before we leave. If you’ve had foundation repair work done - common in Crowley with our shifting Blackland Prairie clay - resealing the duct connections is almost always necessary.
Flex Duct Repair
The flex ductwork installed in Crowley’s 2000s-2010s tracts was builder-grade: thin insulation wrap, minimal support straps, and mastic applied in a hurry. After 15-20 years of attic heat, the wrap peels and the inner liner tears. We cut out damaged sections and splice in new flex with proper support and R-6 or R-8 insulation wrap. A typical flex-duct repair in Crowley runs $180-$340 per section, and we match the diameter and routing of your existing system.
Metal Duct Repair
Some older Crowley homes and custom builds near the original town center have galvanized steel ductwork. We repair rusted sections, reseal longitudinal seams with mastic, and reinforce joints where the sheet metal has separated. Metal duct repair in Crowley typically costs $250-$480 depending on accessibility and the extent of corrosion. We stock 26- and 28-gauge fittings and can fabricate transitions on-site.
Duct Insulation
Unconditioned attics in Crowley hit 140°F in July and August. If your flex duct’s insulation wrap has compressed or degraded, you’re paying to cool air that gains 10-15 degrees before it reaches your bedroom. We rewrap exposed sections with fresh fiberglass insulation and vapor barrier, or replace the flex entirely if the inner liner is compromised. Insulation upgrades run $200-$450 per duct run, and they’re often combined with sealing work for a package price.

Trusted Brands We Service in Crowley
We carry professional-grade equipment and materials from Rotobrush, Nikro, and Honeywell - the same brands serious HVAC contractors specify when they’re building systems meant to last. For Crowley homeowners, that means we don’t have to order parts and make you wait. Our trucks stock flex duct in 6-, 8-, 10-, and 12-inch diameters, mastic sealant, mechanical fasteners, and insulated boots. A repair that might take another company two visits usually gets done in one afternoon.
Common Duct Repair & Sealing Problems We See in Crowley Homes
- Builder-grade flex duct degrades after 15-20 years of 140°F-plus attic heat. The insulation wrap peels away from the inner liner, and the mastic seals at the plenum and boots crack open. We find this in nearly every Crowley home built between 2000 and 2010 - it’s not a flaw in your maintenance, it’s the expected lifespan of the materials that were installed.
- Expansive clay soils shift foundations and stress duct connections. Tarrant County’s Blackland Prairie clay shrinks and swells with seasonal wet-dry cycles, and that movement opens gaps at the supply plenum and register boots. We reseal these connections with flexible mastic that accommodates minor future movement without failing again.
- Fine red-clay dust and agricultural particulates pack into duct elbows. Homes on Crowley’s southern and western perimeter, backing up to hay fields and ranchland, show debris loads that overwhelm standard 1-inch fiberglass filters within weeks. The dust settles in duct elbows where standard rotary brushes can’t reach it - we clear it manually and seal the gaps that let it in.
- Slab settlement separates duct boots from finished ceilings. After foundation repair - common in Crowley - the gap between the boot and the drywall grows, pulling attic air directly into the room. We reinstall and seal the boot to the new slab position, restoring proper airflow and preventing insulation fibers from entering your living space.

FAQs - Duct Repair & Sealing in Crowley
Yes - flex ductwork from that era is now 20 years old and has likely degraded from repeated 140°F-plus attic heat cycles. The mastic seals crack, the insulation wrap peels, and the inner liner becomes brittle. We inspect with our camera and show you exactly what’s failing. Call (866) 347-2063 for a free estimate - we’ll tell you honestly whether sealing, repair, or replacement is the right call.
Crowley’s south-southwest winds carry fine clay dust and crop pollen from adjacent ranchland and hay fields at rates far higher than in fully urbanized suburbs closer to Fort Worth. That debris enters through gaps in your return ductwork, overwhelming standard 1-inch fiberglass filters. Sealing the return system and upgrading to a pleated filter with a higher MERV rating solves the root problem. Call (866) 347-2063 and we’ll inspect for leaks.
Yes - slab settlement from Crowley’s expansive clay soils almost always opens gaps at supply plenums and duct boots. We’ve resealed dozens of homes in Crowley after foundation work, and the gap is usually visible within months of the piers being installed. We recommend scheduling duct inspection within 90 days of foundation repair completion. Call (866) 347-2063 to book - estimates are free.
Yes, and this is our most common repair in Crowley. We cut out the damaged section, splice in new flex with proper support straps, and seal all connections with mastic and reinforced mesh. The new section gets fresh insulation wrap rated for your attic’s temperature extremes. Most single-section repairs are done in under two hours. Call (866) 347-2063 for exact pricing on your home.
For most Crowley homes built during the 2000-2015 boom, staying with flex duct is usually the practical choice - the framing and attic routing were designed for it, and retrofitting metal is expensive. That said, if you’re doing a major renovation or your attic allows straight runs, metal duct with sealed joints and external insulation lasts longer and leaks less. We’ll inspect your specific layout and give you an honest recommendation. Call (866) 347-2063 for a free second opinion if another company has pushed full metal replacement.
