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 Brookshire
Duct repair and sealing in Brookshire, TX typically costs $280-$680 for most residential jobs, with flex duct replacement running $180-$340 per run and full attic sealing with mastic at $450-$890 depending on system size. We’re in Brookshire regularly, dispatching from our Houston office to homes from the historic US-90 corridor out to the newer subdivisions near I-10. Call (346) 666-7165 for a written estimate before any work starts.
Brookshire’s position in the Brazos River flood plain creates a duct problem that doesn’t exist forty miles inland. After Hurricane Harvey, thousands of homes were remediated but never fully gutted, flexible duct runs were dried and treated but left in place, and Waller County’s punishing humidity keeps those compromised systems damp enough to harbor active mold years later. Our crews see it on camera inspections every week. We’re not guessing. We photograph what we find and show you before we quote a price.

Our Duct Repair & Sealing Services in Brookshire
Flex Duct Repair
Brookshire’s flex duct problem is specific and widespread. The 2000s-2010s slab-foundation tract homes near I-10 route supply ducts through attics that exceed 140°F in summer, accelerating liner breakdown. Meanwhile, older homes off US-90 often carry post-Harvey flex that was dried but never replaced. We were called out to a slab home off the US-90 corridor where the homeowner kept getting musty odors every time the blower motor kicked on, and a camera inspection of the supply and return ducts showed the flex duct lining was delaminated and coated in dark microbial growth. Our tech sealed the air handler cabinet with mastic sealant, replaced the compromised flex run, and used negative pressure with HEPA filtration for source removal on the remaining metal trunks, then verified the plenum’s MERV rating matched the Aprilaire filter the homeowner already owned. We don’t treat symptoms. We replace compromised material and document the change.
Duct Sealing with Mastic Sealant
Mastic sealant is the only permanent seal for metal duct joints and air handler cabinets, and it’s especially critical in Brookshire. The mid-70s°F dew points from May through October mean every air leak pulls humid Gulf air into your system, condensing on cooler surfaces and feeding mold colonies in the plenum. But mastic fails fast on wet substrates, and crawl-space or floor-joist runs near the Brazos flood plain often trap enough moisture to compromise adhesion within a season. Our crews test substrate moisture content before applying mastic, and we won’t seal over active condensation without addressing the source. That’s not upselling. That’s not doing the same job twice.
Metal Duct Repair
Older Brookshire homes near the historic downtown corridor sometimes retain original galvanized steel trunk lines from pre-1960s construction. These can corrode at seams, separate at joints, or suffer impact damage from decades of attic work. We repair with matching gauge metal, seal with mastic, and insulate to current standards. The goal is restoring the system’s designed airflow, not patching and hoping.
Duct Insulation
Under-insulated attic ducts are a Brookshire epidemic. When supply runs sit in 140°F attics with R-4 or R-6 wrap, the temperature differential drives condensation against the duct surface, especially where Gulf humidity breaches any gap. We install R-8 insulation minimum on all repaired or replaced runs, sealed at seams with proper vapor barrier. Without it, you’re paying to cool water off your ducts before you cool your rooms.

Parts availability means most Brookshire repairs finish in one visit, with no waiting on specialty orders.
Common Duct Repair & Sealing Problems We See in Brookshire Homes
- Post-Harvey flex duct was dried and treated but never replaced. The outside looks intact. The camera shows compacted river sediment and active microbial growth inside. This is not a cleaning problem. It’s a replacement problem, and we document exactly what we found before quoting.
- Attic supply ducts in 2000s slab tract homes cook at 140°F+ in summer. The duct liner flakes off, humid outside air gets pulled through every breach, and your system works harder to deliver less conditioned air. We find this in subdivisions from the I-10 corridor west toward Sealy.
- Mid-70s°F dew points from May through October condense on under-insulated attic runs. Plenums stay wet enough to recirculate mold spores into living spaces every time the blower cycles. Insulation and sealing together fix this. Sealing alone does not.
- Fogging “sanitiser” upsells mask odors without removing microbial growth. We see this after competitors visit Brookshire homes: pleasant smell for two weeks, then the musty odor returns because the colony is still alive inside the flex duct. Negative-pressure source removal with HEPA filtration is the only documented method we use.
Pricing for Duct Repair & Sealing in Brookshire, TX
Most Brookshire residential duct repair and sealing jobs fall between $280 and $680. Here’s how that breaks down:
- Single flex duct run replacement: $180-$340
- Mastic sealant application to full metal trunk and air handler cabinet: $450-$890
- Duct insulation upgrade (R-8 wrap, typical attic system): $320-$580
- Crawl-space or floor-joist run repair with moisture remediation: $380-$720
What moves you within these ranges: system accessibility (tight attics take longer), extent of compromised material, and whether we’re addressing post-Harvey damage that requires full run replacement versus localized sealing. Every price is written before work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No teaser coupons that balloon once the truck arrives.

FAQs - Duct Repair & Sealing in Brookshire
You need a camera inspection to know for certain, but in our experience across Brookshire’s Brazos River flood plain, flex duct that was dried and treated but not replaced typically still holds compacted sediment and active microbial growth. The outside can look intact while the inside is compromised. We document what the camera shows, quote replacement only for runs that actually need it, and seal the remaining system with mastic. Call (346) 666-7165 to schedule an inspection with photo documentation.
Constant AC operation with persistent musty odor usually means mold colonies are active inside your ductwork, not that your system is dirty. In Brookshire, Waller County’s mid-70s°F dew points from May through October keep attic plenums and flex duct damp enough to sustain growth even when the blower runs continuously. The smell is spores recirculating. Running the fan more won’t dry what’s inside the duct. Source removal with negative-pressure extraction and HEPA filtration, plus sealing the breaches that pull humid air in, is what addresses it. Call (346) 666-7165 and we’ll show you what the camera finds.
No. Fogging masks odor temporarily but does not remove microbial growth colonizing the inside of flex duct. In Brookshire’s humidity, those colonies stay active after the smell fades, and you’ll be back where you started within weeks. CleanRun does not offer fogging as a standalone service. We use mechanical agitation with Rotobrush equipment and negative-pressure extraction with HEPA filtration for documented source removal, then photograph every run so you can verify the difference between real work and chemical cover-up.
Visual inspection from the attic hatch won’t show delaminated liner or internal microbial growth. The signs that matter: uneven cooling between rooms, musty odor when the blower starts, or higher-than-expected humidity readings inside the house even when the AC runs. We use borescope cameras to inspect the full length of each run. In Brookshire’s climate, flex duct installed during the 2000s-2010s building boom is reaching the age where liner breakdown accelerates, especially in superheated attics. The camera tells the truth. We’ll show you.
Mastic can seal leaks permanently, but only on dry substrates. Crawl-space and floor-joist runs near the Brazos flood plain often trap enough residual moisture that mastic adhesion fails within a season. Our crews test moisture content before application. If the substrate is too wet, we address drying first, then seal. Applying mastic over active moisture is not a repair. It’s a redo, and we don’t do redos on the customer’s dime. The 365-Day Done Right Promise means we get it right in writing the first time, or we make it right.
