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.

AfterFast, Reliable Duct Repair & Sealing Across Tomball
Duct repair and sealing in Tomball typically runs $280-$650 for most residential jobs, with flex duct replacement in post-2000 subdivisions landing at the higher end due to attic accessibility challenges. Our crews dispatch from our Houston office and carry Rotobrush and Nikro equipment through Tomball’s master-planned communities daily. We know the difference between a 1970s ranch near Main Street with original metal duct and a 2008 build off the Grand Parkway with flex duct that’s been cooking in a 140°F attic for fifteen summers. Call (346) 248-1474 for a written estimate before any work starts.
Why CleanRun Air Duct Cleaning The Woodlands Is Tomball’s Preferred Duct Repair & Sealing Company
We’ve been driving Tomball’s grid since 2013, and our Duct Repair & Sealing in Tomball work is built on what we can document, not what we can claim. Every job opens with a written price under Haven Standard Clause 1 and closes with a photo record of every duct run, before and after.
Our Tomball customers leave reviews that mention specifics: the camera image of a collapsed flex duct above their garage, the mastic sealant application they watched us apply, the register airflow test we ran before packing up. We don’t chase stars; we chase repeatable results that show up in writing and in photos.
Scheduling is coordinated from our Houston office, but our technicians live in the northwest corridor and know Tomball’s split housing stock cold. They don’t waste time figuring out whether your attic is a truss system over a 2005 Ryland home or a stick-frame original near FM 2920. That local knowledge translates to accurate quotes and fewer return trips.
Haven Standard Clause 3: Verified Crews means every technician is background-checked, uniformed, and identified by name before arrival. No exceptions. No subcontractor roulette.
Our Duct Repair & Sealing Services in Tomball
Flex Duct Repair
Tomball’s post-Grand Parkway subdivisions are entering the danger zone for flex duct failure. The inner liner of flex duct, the plastic sleeve that actually carries air, degrades after sustained exposure to 130-140°F attic temperatures. In homes built between 2000 and 2010, we routinely find this liner crumbling to the touch or collapsed entirely, dumping conditioned air into the attic and pulling fiberglass particulate into living spaces. Our Duct Repair & Sealing process starts with camera inspection, identifies the damaged section, and replaces it with new flex duct secured with mechanical fasteners and sealed with mastic. We verify airflow at each register before we leave. Typical flex duct repair in Tomball runs $340-$580 depending on attic accessibility and linear footage.
Duct Sealing
Leaky ductwork in Tomball doesn’t just waste money. It pressurizes attics and wall cavities, pulling humid Gulf air into places it shouldn’t be. Our sealing process uses mastic sealant, a thick, brush-applied compound that remains flexible for decades, unlike tape that dries and fails. We seal every joint, seam, and penetration in accessible ductwork, then pressure-test the system to verify results. For a typical Tomball home with 8-12 duct runs, sealing runs $280-$450. Homes with original duct board from the 1970s or 1980s may need partial replacement before sealing is viable.
Metal Duct Repair
The older core of Tomball, homes near Main Street and the original railroad corridor, sometimes still runs galvanized steel duct from the 1960s through 1980s. These systems don’t suffer flex duct’s liner collapse, but they do rust at seams, separate at joints, and leak through failed sealant. We repair metal duct with proper sheet metal patches, mechanical fasteners, and mastic sealant. Where rust is advanced, we recommend section replacement. Metal duct repair in Tomball typically falls between $320 and $520.
Duct Insulation
Tomball’s attic temperatures punish duct insulation. Even when the duct itself is intact, degraded insulation means condensation on cool supply lines during our nine-month cooling season, which means moisture, which means microbial growth. We replace insulation with materials rated for our climate zone, properly sealed and supported to prevent the compression that kills R-value. Duct insulation work in Tomball generally runs $380-$650 for a complete system.

Common Duct Repair & Sealing Problems We See in Tomball Homes
- Flex duct liner collapse in post-2000 subdivisions. The Grand Parkway buildout produced thousands of homes with flex duct in unconditioned attics. After fifteen to twenty summers at 130°F-plus, the inner liner degrades and collapses. We find this pattern so predictably in Tomball that camera inspection is standard for any home in this age range.
- Post-Harvey mold colonization. Hurricane Harvey pushed moisture into Tomball attics and crawlspaces that many homeowners never properly dried. Duct systems in those spaces became incubators for mold that still circulates through supply lines. A fogging sanitizer won’t remove established growth; source removal and physical cleaning will.
- Humidity-driven condensation and microbial growth. Tomball sits in the Gulf moisture corridor along Cypress Creek. Relative humidity stays high enough, long enough, that any duct surface below dew point grows something. Proper insulation and sealing prevent the temperature differential that causes condensation in the first place.
- Failed tape seals at plenum connections. The plenum, the central distribution box attached to your air handler, connects to individual duct runs with joints that were originally sealed with tape. That tape dries and fails, especially in Tomball’s extreme attic heat. Mastic sealant is the proper repair, not more tape.

FAQs - Duct Repair & Sealing in Tomball
Signs include weak airflow at registers, rooms that won’t cool evenly, dust accumulation near vents, or musty odors when the system runs. In Tomball’s post-2000 subdivisions, we also recommend a camera inspection if your home was built between 2000 and 2010, since flex duct liner collapse is common in this age range and not always obvious from the living space. Call (346) 248-1474 to schedule an inspection; the fee is credited toward any repair work.
Yes. Tomball’s location in the Gulf moisture corridor means HVAC systems run 8-9 months annually, circulating any dust, mold, or particulate inside ductwork nearly year-round. High humidity also creates condensation on poorly insulated ducts, which feeds microbial growth. Sealing and insulation prevent this; cleaning removes what’s already there. The combination matters more here than in drier climates.
Those subdivisions were built during the 2000s and 2010s with flex duct systems in unconditioned attics. After fifteen to twenty years of 130-140°F summer exposure, the inner liners are failing predictably. This is a materials-aging issue specific to that construction era and that duct type, not a reflection of builder quality. Houston’s older inner-ring suburbs, with metal duct or conditioned crawlspaces, don’t see this pattern at the same rate.
A fogging sanitizer will not fix established mold growth. It deposits chemical on surfaces but does not remove the physical mold colony or the debris it grows on. Source removal, mechanical agitation with a Rotobrush system, and negative-pressure extraction with Nikro equipment physically remove contaminants. In Tomball, where post-Harvey moisture intrusion seeded mold that has had years to colonize, source removal is the only approach that produces a documented result you can see in the photo record.
Yes. Our procedures align with NADCA ACR, the Assessment, Cleaning and Restoration standard, for inspection, cleaning, and repair methods. We document compliance through the photo record and written scope delivered on every job. The 365-Day Done Right Promise backs the work in writing, not as a verbal assurance.

A live person answers, 24/7. We schedule a technician who arrives in a marked vehicle, uniformed, identified by name. They inspect your system with a camera, show you what they found, and deliver a written price before any work starts. The repair is performed, photographed, and verified. You receive the photo record and written warranty. If something isn’t right, we make it right under the 365-Day Done Right Promise.
In a Tomball neighborhood off the Grand Parkway, our tech used a camera inspection and found the flex duct inner liner crumbling and a run partially collapsed above a garage. We performed source removal, sealed the damaged section with mastic sealant and new flex duct, then verified airflow at the registers. The homeowner noticed stronger airflow and less dust right away.
That’s the difference between documented work and vacuum noise. Call (346) 248-1474 for a written estimate on duct repair and sealing in Tomball.
