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 Aldine
Duct repair and sealing in Aldine typically runs $340-$780 for most residential jobs, with flex duct replacement starting around $180 per run and full-system mastic sealing averaging $450-$620. Most Aldine homes we see need a combination: sealing the leaks the camera finds, replacing crushed or torn flex, and addressing the contamination that’s been hiding the damage for years. Our crews dispatch from the Houston office and carry Rotobrush inspection cameras, Guardsman mesh, and mastic sealant on every truck serving Aldine, so we’re not making two trips. Call (346) 423-3631 for a written price before any work starts.
We know Aldine’s housing stock. The 1960s-1980s slab-on-grade ranches along Aldine Bender Road, the properties backing to open pasture off Greens Road, the neighborhoods near the Greens Bayou tributaries that still show Harvey’s fingerprints in their HVAC systems. Our Duct Repair & Sealing team has worked here since 2013, and the patterns are consistent enough that we arrive prepared for what we’ll find.
Why CleanRun Air Duct Cleaning Spring Is Aldine’s Preferred Duct Repair & Sealing Company
We’ve served over 52,000 homes since 2013, and Aldine represents a distinct subset: rural-fringe properties with unpaved road access, original fiberglass duct board, and systems that have never been opened by a professional. Our reputation here is built on showing, not telling. Every job starts with a camera inspection and ends with a Documented Photo Record of every duct run, delivered to you before we leave.
Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Scheduling is coordinated from our Houston office, but the crew that arrives at your Aldine property knows the area: they understand that a home off Aldine-Westfield Road with a gravel drive needs different preparation than a suburban tract, and they carry the right filters and sealing materials for older, uninsulated attic spaces.
We publish our license number on every page, not buried in a footer. We’re insured and bonded, and every estimate comes with our Free Second Opinion: bring a competitor’s written quote, and we’ll put our number next to it. No charge.
Our Duct Repair & Sealing Services in Aldine

Duct Sealing
Most Aldine homes we inspect lose 20-30% of conditioned air through leaks at the plenum, register boots, and crushed flex connections. In rural properties near open land, that leakage also pulls unfiltered dust and pollen into the system. We seal with mastic and fiberglass mesh, not tape that degrades in 150°F attic heat. The camera shows the leak before we touch it; the photo record shows the sealed joint after. Typical duct sealing in Aldine runs $340-$520 for a single-system home.

Flex Duct Repair
Original flex duct in Aldine’s older ranches was never designed for eleven months of continuous AC operation in Gulf Coast humidity. Attics here routinely hit 150°F, and the plastic liner on 1970s-1980s flex becomes brittle, tears at crush points, and sags until it restricts airflow entirely. We replace with new insulated flex, properly supported, and we photograph the before condition so you can see why the room never cooled. Flex duct repair in Aldine typically costs $180-$340 per run, depending on attic access and length.

Metal Duct Repair
Some Aldine homes, particularly those with additions or custom builds from the 1970s, have galvanized metal trunk lines. These corrode at seams and can separate during foundation shift, which is common in the area’s clay soils. We re-seam with mastic and mechanical fasteners, then pressure-test to verify. Metal duct repair in Aldine starts around $280 for accessible sections and ranges to $680 for extensive trunk line work requiring panel removal.

Duct Insulation & Mastic Sealant
Unconditioned attics in Aldine destroy duct insulation. When the R-value drops, condensation forms at every supply boot, creating the mold conditions we regularly document in post-Harvey homes. We remove degraded insulation, seal the underlying duct with mastic sealant (a thick, brush-applied compound that remains flexible and is rated for wet locations), then re-insulate to current standards. Full re-insulation with mastic sealing on a typical Aldine ranch runs $580-$920.

AfterTrusted Brands We Service in Aldine
We carry professional-grade equipment from trade-recognized brands: Rotobrush inspection systems for camera work inside duct runs, Nikro negative-pressure extractors for source removal, and Honeywell and Aprilaire filtration components for replacement after sealing is complete. Our trucks stock Guardsman mesh and mastic for same-day sealing jobs in Aldine, so we’re not ordering parts while your system stays open. You can verify every brand independently; we name them because we have nothing to hide.
Common Duct Repair & Sealing Problems We See in Aldine Homes

- Rural dust and pollen matting original duct board. Properties on unpaved roads or backing to open pasture pull coarse particulate into return plenums, where humid Ship Channel air turns it into a sticky, gray mat. This hides cracks and broken seams until the system is cleaned enough to inspect properly. We see this on Aldine Bender Road, along Greens Road, and throughout the unincorporated fringe.
- Collapsed flex duct above the air handler. Original flex in 150°F attics stretches, sags, and tears. The visible register boot looks fine; the damage is behind the unit where no homeowner checks. Our camera finds it in about forty percent of Aldine’s 1970s-1980s ranches.
- Outbuilding runs contaminating the main system. Detached shops, garages, or converted outbuildings tied into the main blower motor pull unfiltered dust back through the house whenever the main filter is neglected. One bad run can load the entire system.
- Post-flood duct board colonization. Technicians working post-Harvey jobs in Aldine’s older neighborhoods regularly pull return-air grilles to find dried floodwater silt and active mold matted against original fiberglass duct board. The flooding was treated as a flooring and drywall problem, not an HVAC problem, and the contamination has been recirculating for years.
Pricing for Duct Repair & Sealing in Aldine, TX
We don’t do $79 coupons. Every Aldine job gets a written price before work starts, under Haven Standard Clause 1, and that price is flat per system, not per vent.
| Service | Typical Range in Aldine |
|---|---|
| Duct sealing (mastic, single system) | $340 - $520 |
| Flex duct repair / replacement (per run) | $180 - $340 |
| Metal duct repair (accessible section) | $280 - $680 |
| Full re-insulation with mastic sealing | $580 - $920 |
| Post-flood duct board remediation | $620 - $1,200 |
What moves the number: attic accessibility, extent of contamination requiring source removal before sealing, number of flex runs needing replacement, and whether outbuilding ducts require separate handling. Flood-damaged duct board often needs more than sealing; it needs removal and replacement, which we price separately and photograph at every stage. Estimates are free. Call (346) 423-3631.

FAQs - Duct Repair & Sealing in Aldine

Every 3-4 years for properties on unpaved roads or with significant open land exposure, compared to 5-7 years for filtered suburban tracts. The coarse dust and pollen loading in rural Aldine forms a sticky mat on duct board that accelerates liner degradation and hides leaks. We recommend a camera inspection every three years to catch crush points and seam failures before they drive up your energy bill. Call (346) 423-3631 to schedule; estimates are free.
Yes. We regularly find dried floodwater silt and active mold in return plenums of Aldine homes that addressed drywall and flooring but never opened the HVAC system. Fiberglass duct board is particularly vulnerable; once wetted, it remains a mold substrate even when surface-dry. If your Aldine home flooded in 2017 and the ducts were not professionally inspected, we recommend a camera evaluation. Call (346) 423-3631 for a written assessment.
Three consistent reasons: original flex duct has sagged or torn in 150°F attics, register boots have separated from drywall due to thermal cycling, and the plenum itself has unsealed seams that pull attic air into the system. In Aldine’s 1960s-1980s stock, all three are common. Our camera inspection identifies which applies to your home before we quote repair. Call (346) 423-3631 for an exact diagnosis.
Yes. We use mastic and mechanical supports rated for sustained high temperature, not standard tape that degrades in a single summer. Flex duct in Aldine attics needs proper suspension to prevent new crush points, and we specify thicker insulation (R-8 minimum) on replacement runs to reduce condensation at the boot. The photo record shows you the support spacing and insulation rating before we close the attic. Call (346) 423-3631 to discuss your specific attic conditions.
Yes, and we price them as a separate system if they have independent returns or significant contamination loading. Outbuilding runs tied to the main blower are a common source of cross-contamination in rural Aldine properties; we inspect them with the same camera, seal them with the same mastic standard, and document them in the same photo record. Combined house and outbuilding service is typically quoted as a flat package. Call (346) 423-3631 for a written price.
Every CleanRun job in Aldine is backed by our 365-Day Done Right Promise: if the work is not right, we make it right, in writing, not subject to manager approval. You get a written price before we start, a Documented Photo Record of every duct run when we finish, and a crew that knows what Aldine’s climate and housing stock do to HVAC systems.
