Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Repair & Sealing Across Pearland
Duct repair and sealing in Pearland typically costs $280-$650 for most residential jobs, with flex-duct replacement running higher depending on attic accessibility. Most Pearland homes need this work every 10-15 years as their original flex-duct systems age out. Call (346) 251-8919 and we’ll put a written price in your hand before any panel comes off.
We serve Pearland from our Houston office, with crews running daily routes through Shadow Creek Ranch, Silverlake, and Southdown. Pearland’s master-planned subdivisions built during the 2000s and 2010s boom share a common problem: construction debris left in ducts at handover, now compounded by a decade of Gulf Coast humidity and attic heat exceeding 130°F. Our Duct Repair & Sealing team knows these systems. We’ve photographed the inside of thousands of Pearland duct runs, and we’ve documented the same failure patterns from home to home - sagging flex-duct joints, separated seams, and mold colonization that traces back to Hurricane Harvey’s lingering moisture.
Why CleanRun Air Duct Cleaning Houston Is Pearland’s Preferred Duct Repair & Sealing Company
CleanRun has served Pearland since the brand’s founding in 2013, with 52,000+ homes documented across the metro area. Pearland customers receive the same standard we apply everywhere: a written price before work starts, a photo record of every duct run before and after, and the 365-Day Done Right Promise backed in writing on every job.
Our crews know Pearland’s housing stock intimately. The 2,500-4,500 sq ft homes in Shadow Creek Ranch and Silverlake run multi-zone systems with long flex-duct snaking through attics. We’ve traced musty odors to mold inside flex-duct that absorbed Harvey’s moisture in 2017. We’ve found construction debris from 2015 handovers still blowing through registers in 2024. This isn’t generic experience. It’s Pearland-specific fieldwork, documented on every visit.

Our Duct Repair & Sealing Services in Pearland

Duct Sealing with Mastic Sealant
Pearland’s flex-duct joints separate under thermal cycling in 130°F attics. We apply mastic sealant - a thick, fiber-reinforced compound that remains flexible after curing - to every accessible joint and seam. Unlike foil tape, which degrades in Pearland’s attic heat within 2-3 years, mastic sealant holds for the life of the duct system. We verify the seal with a blower-door test or pressure measurement, and we photograph every sealed joint for the job record. A typical mastic sealing job in Pearland runs $280-$420 for a single-zone system, $480-$650 for multi-zone homes common in Silverlake and Shadow Creek Ranch.

Flex Duct Repair
Pearland’s master-planned homes rely almost entirely on flex-duct - the insulated, wire-reinforced plastic tubing that connects your air handler to each room’s register. After 10-20 years in Pearland attics, this material becomes brittle. Sagging sections pool condensation and debris. We’ve replaced entire flex-duct runs in 2012-built Southdown homes where the inner liner had torn, dumping fiberglass insulation into the airstream. Our flex-duct repair includes full run replacement where needed, proper support strapping to prevent future sagging, and connection to metal collars with mechanical fasteners and mastic sealant. Typical flex-duct repair in Pearland: $180-$340 per run, with whole-system replacement for larger homes running $1,200-$2,400.

Metal Duct Repair
Older Pearland homes and commercial buildings with galvanized steel ductwork face rust at seams and joint separation from vibration. We repair metal duct with sheet-metal patches, riveted and sealed, or recommend full section replacement where corrosion has compromised structural integrity. Metal duct repair in Pearland typically runs $320-$580 depending on access and extent.

Duct Insulation Replacement
Post-Harvey moisture intrusion destroyed duct insulation in thousands of Pearland homes along Mary’s Creek and Hickory Slough. Saturated insulation loses its R-value and becomes a mold substrate. We remove compromised insulation, treat the duct surface, and install new fiberglass or closed-cell insulation with a proper vapor barrier. Duct insulation work in Pearland ranges $450-$890 for partial replacement, $1,100-$1,800 for whole-system re-insulation in larger homes.

CleanRun stocks parts and materials from Honeywell, Aprilaire, and Guardsman for Pearland jobs, with Rotobrush and Nikro equipment for source removal and camera inspection. We don’t source from generic suppliers. Every material is named on your written estimate, and every piece is photographed in place before we close the attic access. This matters in Pearland, where the wrong sealant or insulation in a 130°F attic fails within seasons, not years.
Common Duct Repair & Sealing Problems We See in Pearland Homes

- Construction debris from handover still circulating. In Shadow Creek Ranch, we recently inspected a 2018-built home where the homeowner complained of dust on every surface and a musty smell near the registers. Camera inspection showed flex-duct runs sagging in the 130°F attic, collecting construction debris and condensation at the joints - we performed source removal and sealed the leaks with mastic sealant, then verified with a blower-door test that the system was finally tight.
- Flex-duct joints separating under thermal stress. Pearland’s attics exceed 130°F for months each year. The constant expansion and contraction loosens zip-tie and tape connections. Separated joints dump conditioned air into the attic and pull hot, humid attic air into the system. We find this in roughly 60% of Pearland homes over 10 years old.
- Delayed mold from Hurricane Harvey moisture. HVAC technicians in Pearland began flagging a post-Harvey pattern around 2018-2019: homes with no visible flood intrusion were generating musty odor complaints, traced to mold growth inside attic flex-duct that had absorbed moisture during Harvey’s multi-day rainfall event. This delayed contamination problem, specific to Pearland’s position within the Brazos-Galveston floodplain, still generates calls today.
- Clay dust infiltration from Beaumont Clay soils. During dry spells, fine clay particles lift from Pearland’s expansive soils and enter attic spaces through soffit vents. This dust accumulates at flex-duct sag points, mixing with condensation to form a paste that restricts airflow and harbors microbial growth.

FAQs - Duct Repair & Sealing in Pearland

Yes. Homes built during Pearland’s 2000-2020 growth boom were rarely professionally cleaned after construction. Drywall dust, wood particles, and trade debris remain in the supply and return ducts, now compounded by nearly a decade of normal accumulation. The 2015 handover date on your deed doesn’t reflect what’s inside the ductwork. Call (346) 251-8919 for a camera inspection and written estimate - estimates are free.
Pearland’s master-planned subdivisions used longer flex-duct runs than older homes with shorter metal duct paths. These plastic-and-wire tubes degrade faster in 130°F attics, and their sagging sections create debris pools that metal systems don’t. The construction quality during the speed-build years of 2005-2015 also left more debris behind. Newer isn’t always better-built. Call (346) 251-8919 and we’ll show you what’s actually in your system.
Musty odors near registers, especially in summer when humidity peaks, are the most common sign. Visible mold at registers or inside the air handler cabinet indicates advanced colonization. Harvey’s moisture was absorbed into attic flex-duct insulation in 2017; mold manifested 6-18 months later and can persist for years. Only a camera inspection of the duct interior confirms the extent. We include this documentation in every estimate - call (346) 251-8919 to schedule.
We access the attic, inspect every joint and seam with a camera, apply mastic sealant to all connections, replace separated sections with new flex-duct where needed, and verify the system tightness with a blower-door or pressure test. The entire process is photographed before and after. For a typical Pearland single-zone home, this takes 3-4 hours. Written price: $280-$420 for sealing only, higher if flex-duct replacement is needed. Call (346) 251-8919 for your specific estimate.
Every 3-5 years for normal residential occupancy, sooner if you have pets, allergies, or post-construction debris from handover. Pearland’s near-continuous cooling season (March through November) and Gulf Coast humidity accelerate accumulation compared to northern climates. Homes with post-Harvey mold history may need more frequent inspection. Call (346) 251-8919 and we’ll recommend an interval based on what the camera shows inside your specific system.
