Our Duct Repair & Sealing Services in Carrollton
Duct Sealing with Mastic Sealant
Most Carrollton homes we enter have ducts leaking 20-35% of conditioned air into the attic before it reaches the registers. The seams on original duct board - especially in the 1980s subdivisions near Keller Springs Road - have dried and separated under years of thermal cycling. We seal with mastic, a fiber-reinforced paste that remains flexible and bonds to fiberglass, metal, and flex duct. Unlike foil tape, which degrades in Carrollton’s attic heat, mastic holds for the life of the system when applied correctly. A typical mastic sealing job for a single-system Carrollton home runs $280-$450.
Flex Duct Repair
Flex duct in Carrollton’s 1980s builds was installed with minimal support, often draped across trusses or crammed into tight attic bays. Foundation movement from Blackland Prairie clay soils pulls collars loose at the air handler. We replace crushed or separated flex runs with properly supported new material, re-seat collars with mechanical fasteners plus mastic, and insulate to R-6 or R-8 depending on attic conditions. Flex duct repair in Carrollton typically ranges from $180 per run to $890 for multiple runs on a single system.
Metal Duct Repair
Old Town Carrollton and the pockets of pre-1960s housing still contain original galvanized metal duct systems. Decades of debris accumulation at joints, rust-through at low points, and disconnected register boots are standard findings. We repair metal runs with proper sheet-metal patching, re-seal joints with mastic, and replace failed sections rather than applying temporary fixes. Metal duct repair in these older Carrollton homes generally runs $340-$780 depending on accessibility and extent of damage.
Duct Insulation Replacement
Insulation on Carrollton’s attic ductwork has often compressed, torn, or absorbed moisture over 35-50 years. Bare or thinly insulated ducts lose capacity fast in 140°F attics. We replace damaged insulation with new wrap, sealed at all seams, so the air reaching your registers arrives at the temperature your system produced. Insulation replacement on a typical Carrollton system runs $220-$480.
Air Leak Repair
The “pink air” pattern - return plenums pulling loose fiberglass straight off the attic deck - is an air leak problem, not a contamination source you can vacuum away. We locate leaks with smoke testing and camera inspection, then repair with mechanical fastening and mastic sealing. Air leak repair in Carrollton typically falls between $260 and $520 for the primary leak points on a single system.

Common Duct Repair & Sealing Problems We See in Carrollton Homes
- ‘Pink air’ from disconnected flex collars. At a 1983 tract house off Josey Lane, our tech opened the attic and found the flex collar at the air handler pulled loose - the classic pattern, with the return plenum drawing blown fiberglass straight off the deck. We ran a camera inspection on the supply and return ducts, re-seated and mastic-sealed the collar, and re-insulated the run so the system stopped pulling attic material into the living space.
- Degraded duct board shedding fiberglass particles. Carrollton’s late-1970s and 1980s housing corridors - the tract-home belts along Josey Lane, Keller Springs Road, and Belt Line Road - were built with fiberglass duct board and early flex duct that has now spent 35-50 North Texas summers in attics above 140°F, so the liner itself sheds particles into supply air in a way the newer pier-stabilized builds near the Plano border do not.
- Crushed flex runs in tight attics. The 1980s framing in Carrollton’s subdivisions left minimal clearance between trusses. Flex duct was forced into sharp bends or compressed against framing, cutting airflow to far registers and overworking the blower motor. We replace these with properly routed, supported runs.
- Disconnected metal ducts and leaking register boots in Old Town. The original metal systems in and around Old Town Carrollton have accumulated decades of debris at joints and transitions, with sections pulling apart and register boots failing at the floor interface. Camera inspection reveals the extent before we quote repair.

FAQs - Duct Repair & Sealing in Carrollton
It’s almost always a disconnected flex duct collar at the air handler, pulling loose fiberglass directly into the return plenum. Carrollton’s Blackland Prairie clay soils shift seasonally, stressing slab foundations and pulling attic duct joints apart - a pattern we see far more here than in newer, pier-stabilized suburbs. The fix is mechanical re-seating plus mastic sealant, not another cleaning. Call (469) 452-7766 and we’ll camera-inspect to confirm.
Yes. The expansive black-clay soils under Carrollton shift dramatically with moisture changes, cracking slab perimeters and transmitting movement into attic framing. Flex duct collars - especially the early installations in 1980s subdivisions - weren’t designed for this degree of structural flex. We regularly find separated collars and cracked plenum seams that opened within a year or two of foundation movement. Sealing with mastic and proper mechanical support prevents recurrence.
It depends on liner condition. If the fiberglass surface is intact and adhering, mastic sealing at seams and takeoffs extends service life significantly. If the liner is actively shedding particles - common after 35-50 summers above 140°F - replacement is the only permanent fix. We camera-inspect and show you the footage before quoting either path. Replacement of degraded duct board in Carrollton typically runs $890-$1,650 for a single system.
Yes. The original galvanized systems in Old Town and nearby pre-1960s pockets are repairable in most cases. We patch rust-through, re-seal joints with mastic, and replace failed register boots. Camera inspection reveals whether the metal is structurally sound or if section replacement makes more sense. Metal duct repair in these older Carrollton homes generally runs $340-$780.
We don’t seal dirty ducts. Our protocol - Haven Standard Clause 2: Documented Condition - requires camera inspection and, if needed, negative-pressure extraction before any sealing begins. The photo record shows the before condition, the cleaning result, and the sealed final state. You receive all three as part of the standard job deliverable. If your ducts need cleaning first, that’s a separate line item on the written estimate, agreed before work starts.
