Why CleanRun Air Duct Cleaning Katy Is Pecan Grove’s Preferred Duct Repair & Sealing Company

We’ve served over 52,000 homes since 2013, and Pecan Grove represents a significant share of our Fort Bend County work. The reason is straightforward: this community’s 1980s-1990s housing stock and river-bottomland humidity create duct problems that generic cleaning doesn’t fix. Our Duct Repair & Sealing team documents every finding with before-and-after photos of each duct run, delivered as part of the standard job record.

Pecan Grove homeowners tend to research before calling. They ask about our license, our equipment, and whether we’ll put a price in writing. We answer all three on the first call. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number on every page - not buried in a footer. The 365-Day Done Right Promise applies to every Pecan Grove job in writing, not as a verbal afterthought.

Dispatch and scheduling are coordinated from our Houston office, but crews serve Pecan Grove locally and carry common flex duct sizes, mastic sealant, and collar fittings for the 6-inch and 8-inch runs standard in this community’s homes. That local inventory means most repairs finish in one visit.

Our Duct Repair & Sealing Services in Pecan Grove

Duct Sealing

Sealing is where most Pecan Grove homes actually need work. Original mastic sealant from the 1980s and 1990s has hardened and cracked under years of 130°F attic heat, opening leak paths at the air handler plenum, register boots, and collar joints. We remove the failed material, prep the metal or flex surface, and apply fresh mastic sealant rated for the temperature swings these attics see. A typical sealing job in Pecan Grove runs $280-$450 for a single-system home, with the written price delivered before work starts under Haven Standard Clause 1.

Flex Duct Repair

Pecan Grove’s flex-duct systems are now 25-40 years old. The outer vapor barrier degrades. The inner liner tears where support straps have constricted it. Sagging sections dip below the dew point and collect condensation that rots the jacket from the outside in. We replace compromised runs with new insulated flex duct, support it properly to maintain slope, and seal all connections with mastic - not just foil tape that will fail again in two summers. Flex duct replacement in Pecan Grove typically ranges from $180 per run for accessible attic sections to $340 per run where decking or insulation must be moved.

Metal Duct Repair

Some Pecan Grove homes, particularly the earlier builds from the late 1970s, have galvanized metal trunk lines with later flex-duct branches. These metal sections rust at seams and joints where condensation has pooled for decades. We cut out corroded sections, fabricate replacements, and seal with mastic and mechanical fasteners. Metal repair runs higher - $340-$620 depending on accessibility and extent - but it’s often the only way to stop a leak path that’s been pulling 130°F attic air into the system for years.

Duct Insulation

When the fiberglass insulation surrounding a flex duct has absorbed moisture and compacted, the duct loses thermal efficiency and begins sweating on its exterior surface. In Pecan Grove’s humid attics, this creates a cycle of condensation and mold growth. We strip compromised insulation, replace it with new fiberglass wrap or pre-insulated flex, and seal the vapor barrier. Insulation replacement typically adds $120-$220 per run to the repair cost.

Common Duct Repair & Sealing Problems We See in Pecan Grove Homes

• Soggy flex duct insulation from river-bottomland humidity. Pecan Grove’s Brazos River bottomland setting floods attics with dew points that stay high even in cool months, so 1980s-1990s flex duct sweats from the outside in - meaning duct repair calls here often uncover soggy, moldy insulation around otherwise-intact runs, not just disconnected joints. The fix is insulation replacement and improved support to maintain proper slope.
• Collapsed runs from roof deck settlement. On a 1988 home off Plantation Drive in Pecan Grove, our techs were called for weak airflow and a musty smell in a back bedroom. Camera inspection found the flex run to the master bath crushed where a roof deck had settled, and the liner was sweating so badly that mastic sealant had peeled away from the collar - we replaced the run, re-sealed with fresh mastic, and the supply register went from barely-there to full volume in one visit.
• Post-Harvey mold contamination in ground-level equipment. Hurricane Harvey’s record Brazos River crest in 2017 flooded portions of Pecan Grove and caused water intrusion into ground-level air handlers and return plenums across the community. Many of those systems were dried out and restarted without professional mold remediation of the ductwork, leaving a significant share of homes with contaminated duct systems that have been quietly recirculating mold spores ever since. We find this during camera inspection and recommend appropriate remediation before sealing work proceeds.
• Failed mastic at air handler collars. Mastic sealant and foil tape on original 1980s collars fail under 130°F attic heat, opening air leak paths at the air handler and register boots that pull attic humidity straight into living spaces. The gap is often invisible from the register side; we find it with blower-door testing or smoke pencil inspection.
