We’ve been working in Richardson since 2013, and the pattern is consistent: neighborhoods built during the 1960s-1980s boom still move on Blackland Prairie clay, and that movement keeps finding new ways to pull ductwork apart. Our Duct Repair & Sealing team doesn’t guess at what’s wrong. We run a camera through every accessible run, photograph what we find, and show you the gap or crack before we quote the fix.

Richardson homeowners have left us detailed reviews mentioning the same thing: they chose us because we showed them photographs of their own ducts before proposing work. That documented record, included on every visit since our first job in 2013, is how we operate under the H.A.V.E.N. Standard. Haven Standard Clause 1 requires a written price before any panel comes off. No exceptions.

Dispatch and scheduling are coordinated from our Dallas-Fort Worth office, but crews serve Richardson with local knowledge: we know which Canyon Creek ranches still run original fiberglass-lined metal, which Spring Valley neighborhoods see the worst clay heave, and where to check first when a homeowner reports dust film on furniture that returns within days of cleaning.

Our Duct Repair & Sealing Services in Richardson

Flex Duct Repair

Flex duct in Richardson’s older homes fails differently than in newer construction. The Blackland Prairie clay beneath Canyon Creek, Spring Valley, and the neighborhoods flanking US-75 expands and contracts seasonally, shifting slabs and pulling flex duct boots away from floor registers. The gap is often hidden under carpet. Our crew re-secures boots to the subfloor, replaces crushed or torn flex runs, and verifies airflow at each register with a digital manometer. Typical flex duct repair in Richardson runs $180-$420 per run, depending on attic or crawl-space access.

Duct Sealing

Sealing in Richardson means addressing leaks that generic duct cleaners miss. We use mastic sealant and fiberglass mesh at trunk-line joints, apply aerosol sealant for inaccessible leaks, and focus on the air-handler plenum (the distribution box attached to your furnace or air handler) where temperature differentials cause the worst cracking. A typical duct sealing job for a 1,500-2,500 square foot Richardson ranch runs $450-$850. Whole-system sealing with aerosol injection for homes with extensive leakage reaches $900-$1,400.

Metal Duct Repair

Original galvanized steel trunk lines in 1960s-1980s Richardson homes corrode at seams and where fiberglass liner has trapped moisture. We cut out deteriorated sections, fabricate replacement duct from 26-gauge galvanized stock, and re-insulate with foil-faced duct board. Metal repair is more common in Richardson than in newer suburbs because so much original ductwork remains in service. Expect $320-$680 for sectional replacement, with full trunk-line rebuilds on larger homes reaching $1,100-$1,800.

Duct Insulation & Mastic Sealant

Uninsulated or poorly insulated ductwork in Richardson attics loses 20-30% of cooling capacity during May-September stretches when attic temperatures exceed 140°F. We install R-6 or R-8 foil-faced insulation on accessible runs and apply mastic sealant (a thick, brush-applied paste that remains flexible after curing) at every joint and penetration. Mastic outperforms foil tape long-term, especially where vibration from the air handler causes tape to peel. Insulation and sealing together typically run $550-$950 for Richardson homes with partial attic ductwork.

Common Duct Repair & Sealing Problems We See in Richardson Homes

• Clay-soil slab movement pulls flex boots loose from registers. In Canyon Creek and similar subdivisions, we’ve found gaps of 1-3 inches between flex duct boots and subfloor, hidden under carpet for years. The suction pulls attic debris, insulation fragments, and rodent droppings directly into the living space.
• Fiberglass duct liner from the 1960s-80s deteriorates and sheds fibers. Original liner in Richardson trunk lines breaks down into airborne particles that load the blower motor and recirculate through supply vents. The camera shows it as a gray, fuzzy coating that wipes away to expose bare metal.
• Extended cooling seasons crack mastic and separate flex seams. Richardson’s 100°F+ stretches from May through September cycle enormous air volumes. The constant expansion and contraction at air-handler connections - where metal meets flex - causes mastic to craze and tape to fail.
• Mature tree canopy loads pollen at outdoor intakes. Richardson’s established neighborhoods with oak and elm canopy see heavy mountain cedar, elm, and ragweed pollen that accumulates on return-air grilles and accelerates filter loading, increasing negative pressure that pulls leaks open wider.
