We know the local housing stock here. The late-70s through early-2000s brick-veneer tract homes with flex duct in unconditioned attics. The post-Harvey moisture issues that linger in floor-level returns. That knowledge saves Pecan Grove homeowners time and money on diagnostics.
Our Duct Repair & Sealing Services in Pecan Grove
Flex Duct Repair
The bulk of Pecan Grove’s housing stock consists of single-family brick-veneer tract homes built between the late 1970s and early 2000s, when flexible duct systems in unconditioned attic spaces became standard. Those original flex ducts are now 20-40 years old, and the attic heat here cooks them. We regularly find inner liner deterioration, compressed runs that trap debris, and delaminated sections hanging in shreds. On a 1980s brick-veneer home near the Brazos levee, we found the original flex duct inner liner had delaminated and was hanging in shreds, choking airflow to the second bedroom. We replaced the damaged run with new R-8 insulated flex duct and sealed all accessible return boots with mastic, restoring balanced cooling that the homeowner hadn’t felt in years. A typical flex duct repair or partial replacement in Pecan Grove runs $280-$650 depending on linear footage and attic accessibility.

Mastic Sealant Application
Tape dries out. Especially in Pecan Grove, where attic temperatures spike and humidity never really lets up. We seal accessible joints, plenum connections, and return boots with professional-grade mastic sealant that remains flexible and airtight for years. This is the correct material for lasting duct sealing, not the foil tape that peels in three seasons. For a full mastic sealing of accessible ductwork in a typical Pecan Grove home, expect $450-$890. We quote the exact scope before we start.

Metal Duct Repair
Some Pecan Grove homes, particularly earlier builds near Plantation Drive and the original Pecan Grove sections, have galvanized metal trunk lines with takeoff branches. Metal ducts don’t delaminate like flex, but they rust at seams, separate at joints, and suffer from failed fiberglass liner. We patch, re-seam, and re-line metal ductwork where it makes sense, and we’ll tell you straight when a section is too far gone to repair economically. Metal duct repairs in Pecan Grove typically fall between $320-$780.

Duct Insulation Replacement
Pecan Grove’s position on the Brazos River bottomlands creates ambient relative humidity that routinely exceeds 80% even in winter, accelerating microbial growth on duct liner surfaces faster than is typical even a few miles inland. Wet or degraded insulation around your ductwork wastes energy and can harbor mold. We replace damaged duct insulation with new R-6 or R-8 wrap, properly sealed and supported. Insulation replacement for accessible runs in Pecan Grove homes generally costs $380-$920.

Common Duct Repair & Sealing Problems We See in Pecan Grove Homes
- Original flex ducts from the 1980s-90s develop inner liner delamination and compressed runs from attic heat, causing airflow loss and debris trapping. The eight-plus months of AC operation per year means systems rarely get a rest cycle that would allow ducts to dry out between cooling seasons.
- Post-flood silt and mold colonies hidden inside sealed return-air boots go unreported because exterior walls dried, but ductwork held moisture for months. Technicians working post-Harvey homes in Pecan Grove regularly find dried silt deposits and visible mold colonies inside floor-level return-air boots that homeowners never reported to insurers, because the exterior walls dried out but the sealed ductwork held moisture for months - a failure mode almost nonexistent in the higher-elevation subdivisions to the west.
- High ambient humidity (routinely above 80%) accelerates microbial growth on duct liner surfaces, especially in systems that run AC 8+ months without a dry-out cycle. This is a Pecan Grove-specific pattern we don’t see at this severity in drier inland suburbs.
- Tape-sealed joints fail prematurely in unconditioned Pecan Grove attics, where summer temperatures exceed 140°F and winter humidity penetrates every gap. Mastic is the only lasting solution here.

FAQs - Duct Repair & Sealing in Pecan Grove
If your upstairs rooms never reach the thermostat setting, you feel weak airflow from some vents, or your energy bills have climbed without explanation, your 1992 flex ducts are likely delaminated or compressed. We camera-inspect every system we touch, so you’ll see the damage rather than guess. Call (866) 347-2063 for a free inspection - estimates are free.
Yes, and this is a specific Pecan Grove concern we address regularly. In Pecan Grove’s flood-prone Brazos River bottomlands, floor-level return-air boots frequently trap dried silt and mold from Harvey-era inundation that never got reported, creating a hidden duct contamination pattern absent in higher-elevation suburbs. Exterior walls dried. The sealed ductwork didn’t. We find visible mold colonies and silt deposits in returns that homeowners assumed were fine. A camera inspection will tell you definitively. Call (866) 347-2063 - we’ll check it at no charge.
Mastic is a thick, brush-applied compound that cures into a flexible, permanent airtight seal. Tape, even “duct tape,” dries out and peels, especially in Pecan Grove attics where heat and humidity attack adhesives. We use mastic on every accessible joint because it lasts. Tape is for temporary repairs, not for a home you plan to stay in. Want your ductwork sealed right the first time? Call (866) 347-2063.
Yes. Some original Pecan Grove sections and homes near Plantation Drive have galvanized metal trunk lines. We patch rusted sections, re-seam separated joints, and replace failed internal liner. We’ll also tell you honestly when a metal section is too deteriorated to repair economically and a replacement makes more sense. Call (866) 347-2063 for an exact assessment - estimates are free.
Pecan Grove’s ambient humidity routinely exceeds 80% even in winter, and with AC running eight or more months annually, duct insulation rarely gets a dry-out cycle. Wet insulation loses R-value, sags away from the duct, and becomes a mold substrate. We replace degraded insulation with properly rated R-6 or R-8 wrap and ensure it’s sealed against moisture intrusion. If your ducts sweat in summer or you smell mustiness from the vents, your insulation may be compromised. Call (866) 347-2063 for a free inspection.
