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 Aldine
Duct repair and sealing in Aldine, TX typically runs $280-$650 for most residential jobs, with full flex duct replacement on post-flood homes reaching $1,200-$2,400 depending on how many runs were saturated. We’re dispatched to Aldine from our Houston office, and crews are familiar with the unincorporated-era housing stock off Aldine Mail Route, the neighborhoods near Greens Bayou, and the repeated flooding patterns that make duct decisions here different from anywhere else in Harris County. Call (346) 248-1474 for a written estimate - we deliver the full price before any panel comes off.
Why CleanRun Air Duct Cleaning The Woodlands Is Aldine’s Preferred Duct Repair & Sealing Company
We’ve worked Aldine since 2013, and the pattern is unmistakable. Homes near Little Cypress Creek and along the lower stretches of Aldine Mail Route keep showing us the same thing: new air handlers bolted to old, water-damaged ductwork. Our Duct Repair & Sealing team documents every finding with photos and moisture readings, not opinions.
Our crews know the local housing stock - the 1960s-1980s tract homes with original fiberglass-lined metal ductwork, the post-Harvey quick repairs that stopped at the air handler, the attics where unsealed joints hide under blown insulation until the registers start weeping condensation. That knowledge changes what we find and how we fix it.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We identify crew members by name before arrival. The 365-Day Done Right Promise applies in Aldine exactly as it does everywhere else - in writing on every job, not subject to manager approval.
We also offer a Free Second Opinion on any written estimate from another company. Bring us their number; we put ours next to it in writing, no charge.
Our Duct Repair & Sealing Services in Aldine
Flex Duct Repair
Flex duct is the weak link in most Aldine homes that flooded. The inner plastic liner tears, the fiberglass insulation matts with sediment, and the wire helix corrodes. We see this constantly in post-Harvey repairs off Greens Bayou - the air handler got swapped in 2017, the flex duct stayed. Our flex duct repair in Aldine means replacing saturated runs with new, sealed flex or transitioning to rigid metal where the attic layout allows. We photograph the damage, record moisture content, and deliver a written clean-versus-replace finding before any removal starts. Haven Standard Clause 1: Written Price Before Any Work Starts.
Duct Sealing
Unsealed duct joints in Aldine’s older homes leak conditioned air into attic spaces that regularly hit 130°F in July. That pressure loss means the AC runs longer, humidity creeps higher, and mold finds its foothold. We seal with mastic sealant (a thick, fiber-reinforced paste that remains flexible) at every takeoff, boot, and longitudinal seam. For homes with documented water intrusion, we pressure-test the system after sealing to confirm no cross-contamination between return and supply sides. In Aldine’s floodplain, a sealed system is also a contained system - critical when you’re trying to prove to an insurer that remediation was thorough.
Metal Duct Repair
The original galvanized metal ductwork in Aldine’s 1960s-1980s tracts corrodes from the inside out where standing water sat after Harvey or subsequent overbank events. We cut out damaged sections, fabricate replacements on-site, and seal with mastic and fiberglass mesh. Where metal duct has been patched repeatedly with tape (we see this often near Aldine Bender Road), we replace the full section - tape failures in humid attics are predictable, and we don’t install repairs we expect to fail.
Duct Insulation
Uninsulated or under-insulated ductwork in Aldine sweats. With outdoor relative humidity routinely above 70-80% and attic temperatures spiking, cold supply air condenses on the duct exterior, dripping onto ceiling drywall and saturating insulation below. We install R-8 insulation on all new and repaired runs - the current code minimum, and a significant upgrade over the R-4 or uninsulated duct common in original Aldine construction. Proper insulation also prevents the condensation cycle that reactivates mold spores in previously flooded systems.

BeforeAfterTrusted Brands We Service in Aldine
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct runs, Nikro negative-pressure extractors for controlled debris removal, and Honeywell media filters and zoning controls where we’re rebuilding systems from the air handler out. We stock common flex duct diameters, mastic, and R-8 insulation wrap locally, so Aldine jobs don’t wait on parts. Every brand we name is one you can look up independently - we don’t make performance claims beyond what the manufacturer publishes.
Common Duct Repair & Sealing Problems We See in Aldine Homes
- New air handler, old soaked duct. Post-flood partial repairs in Aldine left mold-saturated flex duct connected to replaced equipment. We camera-inspect to prove whether the duct itself is salvageable - documentation that adjusters accept.
- Fiberglass liner that stays damp. Aldine’s 70-80% outdoor humidity keeps interior liner wet enough that frays and mold return even after surface cleaning. We test moisture content at multiple points; readings above 16% mean replacement, not cleaning.
- Unsealed joints hidden by attic insulation. In unincorporated-era homes here, leaks at takeoffs and boots go unseen until condensate staining and pressure loss show up at the registers. We map the system with a pressure pan to find leaks the eye misses.
- Collapsed flex duct at low points. Water pooling in attic ductwork from roof leaks or past flooding crushes the inner helix. The system still moves air, but at reduced volume and higher velocity - noisy, inefficient, and hard on the blower motor.
Pricing for Duct Repair & Sealing in Aldine, TX
A typical mastic sealing job for a single-system Aldine home runs $280-$450. Flex duct repair or partial replacement on 1-3 branches runs $340-$650. Full flex duct replacement on a post-flood home with saturated runs throughout the system ranges $1,200-$2,400, depending on home size and attic accessibility. Metal duct section repair with custom fabrication runs $180-$420 per section. Duct insulation upgrade to R-8 runs $2.80-$4.20 per linear foot.
What moves the number: how many runs are involved, whether the attic requires protective flooring for safe access, and whether we’re working around stored belongings common in Aldine’s older homes. Flood-damaged systems requiring full documentation for insurance add no extra labor cost - the photo record and written findings are standard on every CleanRun job. We deliver one flat price per system, agreed in writing before work starts. No per-vent pricing. No add-ons after the truck arrives. Call (346) 248-1474 for an exact quote - estimates are free.

FAQs - Duct Repair & Sealing in Aldine
No. If the flex duct or fiberglass liner was saturated, cleaning will not restore it. We camera-inspect and moisture-test; readings above 16% or visible mold on the liner means replacement, not cleaning, and we document this for your adjuster. Call (346) 248-1474 to schedule an inspection - estimates are free.
Aldine’s Gulf Coast humidity keeps attic ductwork in a constant condensation cycle from April through October. Uninsulated or poorly sealed ducts sweat, corrode, and grow mold without ever seeing floodwater. The 1960s-1980s housing stock here was built with materials and methods that assumed drier climates. Call (346) 248-1474 for a system evaluation - estimates are free.
We use three criteria: moisture content below 16% throughout the run, structural integrity of the inner liner or metal wall, and no visible mold penetration beyond surface spots. If all three pass, we seal with mastic and pressure-test. If any fail, we replace and document why. Call (346) 248-1474 for a written finding - estimates are free.
Yes. Every CleanRun job includes a Documented Photo Record - before and after photos of every duct run, moisture readings, and a written scope of work. For insurance purposes, we add a clean-versus-replace finding with specific observations tied to each photo. Haven Standard Clause 1 requires the written price before work starts; the documentation package is standard deliverable. Call (346) 248-1474 to discuss your claim - estimates are free.
Rotobrush rotary systems for mechanical agitation inside duct runs, Nikro negative-pressure extractors for debris removal, and Honeywell controls and filtration where we’re rebuilding from the air handler out. We also use digital moisture meters, pressure pans for leak detection, and borescope cameras for internal inspection. Every tool is named so you can verify specifications independently. Call (346) 248-1474 with equipment questions - estimates are free.
On a call off Aldine Mail Route near Greens Bayou, our tech opened a return plenum on a 1972 tract home and found the air handler was a 2018 replacement - but the original fiberglass-lined flex duct behind it was still wet-stained at the low runs, with a musty odor pulling through the registers every time the blower motor kicked on. We ran a camera inspection through the supply and return ducts, documented saturated liner and collapsed inner core on three branches with photos and moisture readings, and gave the homeowner a written clean-versus-replace finding their adjuster accepted - then rebuilt those runs in sealed metal with mastic and R-8 insulation.
In Aldine’s post-Harvey partial insurance repairs, crews routinely find that the air handler was replaced but the connected flex duct that also soaked was left in place - so a brand-new unit pushes air through mold-saturated ductwork. Because Greens Bayou and Little Cypress Creek repeatedly overtop in this stretch of unincorporated Harris County, duct decisions here hinge on documented water-intrusion history, not just visible dust. This is the gap left by 2017-2018 partial repairs across this floodplain, and it’s why we treat every Aldine job as a documentation project first.
Ready to know what’s actually inside your ductwork? Call (346) 248-1474 for a written estimate. We’ll deliver one flat price per system before any work starts, photograph every run before and after, and back the job with our 365-Day Done Right Promise - in writing, not as a policy subject to approval.
