Our Duct Repair & Sealing Services in Richmond
Flex Duct Repair
Flex duct is the dominant duct type in Richmond’s master-planned communities, and it’s where we spend most of our repair hours. In Richmond’s 2000s-era subdivisions like Long Meadow Farms and Grand Mission, unconditioned attics regularly exceed 150°F in summer, degrading flex duct inner liners to shredding or collapse, making duct repair and sealing a common need alongside cleaning. Our crew recently handled a duct repair in a Long Meadow Farms home where the original 2004 flex-duct inner liner had degraded so badly that it collapsed in several runs, blocking airflow entirely. We replaced the damaged sections with insulated flex duct and sealed all connections with mastic, restoring HVAC performance in the 3,500 sq ft home. A typical flex duct repair in Richmond runs $320-$680 depending on linear footage and accessibility.

Duct Sealing
Even ducts that look intact can leak 20-30% of conditioned air into your attic. In Richmond, where HVAC systems run close to year-round, that’s money you’re paying to cool a space you never enter. Our Duct Repair & Sealing team pressurizes your system and uses smoke testing to pinpoint every leak, then seals them with professional-grade mastic or foil-backed tape rated for Texas attic conditions. Duct sealing in Richmond typically costs $280-$550 for an average 2,500-3,500 sq ft home.

Metal Duct Repair
Pecan Grove and Greatwood’s older homes often have galvanized metal ductwork from the 1980s and 90s. These systems corrode at seams and develop pinhole leaks from decades of humidity exposure. We patch metal sections, replace rusted fittings, and seal joints with mastic formulated for metal-to-metal bonds. Metal duct repair in Richmond generally runs $350-$720 depending on the extent of corrosion and whether sections need full replacement.

Duct Insulation
When flex duct outer insulation gets wet from condensation or torn by rodents, the R-value drops and your attic becomes a heat sink. In Richmond’s humid Brazos River bottomlands, this isn’t an occasional problem. It’s a pattern. We replace damaged insulation with new flex duct or wrap existing metal ducts with formaldehyde-free insulation, sealed at every seam. Insulation repair or replacement in Richmond typically runs $400-$850.

Mastic Sealant Application
Mastic is the only sealant we trust for lasting results in Richmond’s climate. Brush-on mastic forms a flexible, permanent bond that expands and contracts with temperature swings without cracking. We apply it to every joint, seam, and connection after repair or cleaning work. This is standard on every job, not an upsell.

Common Duct Repair & Sealing Problems We See in Richmond Homes
- Collapsed flex-duct liners from attic heat. In 2000s-era subdivisions like Long Meadow Farms and Grand Mission, original flex duct has spent fifteen to twenty summers in 150°F attics. The inner liner degrades to the point of shredding or complete collapse, blocking airflow to entire zones of the house.
- Pinhole leaks at duct joints from humidity and age. Pecan Grove’s 1980s-90s builds often have original metal ductwork where decades of Richmond humidity have corroded seams and loosened connections. These leaks are invisible from below but show up as hot rooms and high electric bills.
- Mastic sealant failure along long attic runs. In Harvest Green and other newer communities, seasonal humidity cycling breaks the bond of lower-quality sealants applied during original construction. We find gaps where conditioned air has been escaping for years.
- Mold colonization inside flex duct liners. Richmond’s position on the Brazos River floodplain means relative humidity stays elevated even by Houston-metro standards. Prolonged condensation cycles inside flex ducts make mold growth a genuine and recurring problem, not an edge case.

FAQs - Duct Repair & Sealing in Richmond
Richmond’s combination of extreme attic heat and sustained humidity degrades duct materials faster than in drier climates. Unconditioned attics in 77406 and 77407 regularly exceed 150°F in summer, breaking down flex duct liners and mastic bonds, while year-round humidity corrodes metal seams and promotes mold. If you’re seeing uneven cooling or rising electric bills, call (866) 347-2063 for a free inspection.
Yes. We replace collapsed sections with new insulated flex duct and seal all connections with mastic, typically completing the repair in a single visit. Grand Mission’s original 2004-2008 flex duct is now hitting the age where we see this failure routinely. Most Grand Mission flex duct repairs run $380-$650. Call (866) 347-2063 for an exact quote.
Yes, especially for 2005-era construction where original mastic may have failed from humidity cycling. Sealing can reduce HVAC runtime by 20-30% and often pays for itself within two cooling seasons in Richmond’s climate. Harvest Green duct sealing typically costs $300-$520. Call (866) 347-2063 for a free estimate.
Look for rooms that won’t cool evenly, dust blowing from vents, or a musty smell when the AC runs. Pecan Grove’s 1980s-90s metal ductwork often shows corrosion at seams and pinhole leaks from decades of humidity exposure. We camera-inspect to confirm before quoting any work. Call (866) 347-2063 to schedule.
Richmond’s Brazos River bottomland humidity means condensation forms inside and on ductwork year-round. Once insulation gets wet or torn, it loses R-value and becomes a breeding ground for mold. Repairing insulation prevents both energy waste and air quality problems. Most Richmond insulation repairs run $400-$850. Call (866) 347-2063 for a free assessment.
