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 Air Duct Repair Across La Marque
If the air coming through your vents smells stale, musty, or carries a faint chemical odor, the ductwork itself is likely the problem. That’s common in La Marque, where near-constant humidity and proximity to the Texas City petrochemical complex mean ducts collect contamination faster than almost anywhere else in Galveston County. Our crews know exactly where La Marque duct systems fail: attic runs sagging under 130 degree heat, post-Ike patch jobs quietly growing mold behind drywall, and low points pooling industrial fallout from the refineries to the east. We repair and replace ductwork throughout La Marque, from Highland Bayou to Omega Bay to the neighborhoods off FM 1765. Call (980) 447-2498 and we’ll schedule a camera inspection, give you a written price, and get the job done right.
Why Linden Air Duct Cleaning Is La Marque’s Preferred Air Duct Repair Company
We are part of the Threshold Group family and we’ve held ourselves to the Threshold Verified standard since 2004. What that means in practical terms for a La Marque homeowner: the technician who arrives at your door has already been background-checked, identity-verified, and introduced to you by name and photo before the visit. When they knock, they’ll show a photo ID badge. We don’t send subcontractors. We don’t send someone you couldn’t pick out of a lineup.
That matters in La Marque, where most homes were built in the 1950s through 1970s and many still run original or patched duct systems. You’re not calling about a hypothetical. You’ve got a real problem, usually involving mold, industrial dust, or a sagging flex run in a 140 degree attic. Our Air Duct Repair team has worked on exactly these homes. We know which post-Ike repairs are likely to hide active mold and which sections of flex duct are prone to sagging under Gulf Coast heat. Marcus Veale, who leads our team, has spent years working these neighborhoods and he will tell you straight: some ducts can be repaired, some need to be replaced, and we’ll show you the difference with a camera, not a sales pitch.
Ductwork Repair in La Marque
Ductwork Repair in La Marque usually means fixing what’s broken without pulling everything out: resealing leaking joints, patching pinholes, replacing a crushed or torn flex section, or re-supporting a run that’s sagged under attic heat. In La Marque’s older ranch homes, we routinely find duct sections that were patched after Hurricane Ike in 2008 and never properly addressed since. The repair question is always whether the material is sound enough to save. A disconnected or torn flex run off FM 1765 can often be reconnected or replaced section-by-section for $275 to $600. A leaking sheet metal plenum might run $300 to $700 depending on access. We use professional-grade equipment from Rotobrush and Nikro for inspection and cleaning, and we stock common parts locally, so a repair typically doesn’t mean waiting on a shipment from Houston.
Resealing and Re-supporting
Older duct systems leak. In La Marque, the bigger issue is that attic heat degrades tape and mastic, and the flex duct liner breaks down over years of 130 – 140°F summers. We reseal joints with proper mastic and re-support sagging runs so debris stops pooling at the low points.
Patch and Partial Replacement
When a section of duct has collapsed, been chewed through by rodents, or torn by a previous contractor, we remove that section and replace it with new insulated flex or sheet metal. The rest of the system stays put. That keeps the cost down and fixes the actual problem.
Duct Replacement in La Marque
Duct Replacement in La Marque is what we recommend when cleaning and patching won’t solve the problem: flood-damaged ducts with active mold inside, flex duct with degraded liner shedding insulation into your air stream, or systems so patched and leaky that repair would cost more than starting fresh. A full duct replacement in an average La Marque ranch home typically runs $2,800 to $5,500, depending on the number of runs, attic accessibility, and whether the plenum and boots need to be replaced too. Partial replacement of a single compromised run usually falls between $450 and $1,200. Before we quote anything, we run a camera through the system and show you what we found. Then you get a written price before any work begins. Every replacement is covered by our written guarantee, and if a covered repair fails within 365 days, we return at no charge.
Flood-Damage Replacement
This is the big one for La Marque, especially near Highland Bayou. We’ll cover it in detail below, but the short version: if floodwater got into the ducts in 2008 and someone taped over the damage, that mold is likely still active. Cleaning won’t fix it. Replacement is the only reliable option.
Full System Replacement
When a 1960s home still has its original duct runs, the insulation is often crumbling and the system leaks 20 to 30 percent of conditioned air into the attic. Replacing everything gives you a sealed, efficient system that won’t keep pulling attic dust into your living room.
Trusted Brands We Service in La Marque
We use professional-grade equipment from Rotobrush and Nikro on every La Marque job, from camera inspections to negative-pressure extraction. For air-quality concerns caused by industrial fallout from the Texas City plants, we install and service filtration products from Abatement Technologies, Aprilaire, Honeywell, and Guardsman. Because we carry these brands and stock common parts for the La Marque market, we can usually source what your repair needs without sending you to a big-box store or asking you to wait a week. If you’re dealing with fine particulate from refinery emissions or mold spores from post-Ike moisture, we’ll recommend the right filtration upgrade for your system and explain exactly what it will and won’t do. No scare tactics, just straight answers.
Common Air Duct Repair Problems We See in La Marque Homes
- Post-Ike mold colonies sealed inside ducts: Homes near Highland Bayou and other lower-elevation areas that took floodwater in 2008 often had flex duct taped over rather than replaced. Over 15 years later, active mold is still growing inside those sealed sections, and it’s a primary driver of indoor air quality complaints in older La Marque rental stock.
- Sagging flex duct in 130-degree attics: Attic-run flex duct is nearly universal in La Marque’s 1950s – 1970s ranch homes, and Gulf Coast summer heat routinely pushes attic temperatures past 130°F. The duct liner degrades, the run sags, and debris pools at the low points, then blows into the home.
- Debris from degraded liner insulation: As flex duct liner breaks down in the heat, it sheds fine insulation fibers that get pushed through the vents. You’ll see it as a powdery dust on furniture near registers, and it won’t stop with cleaning because the liner keeps degrading.
- Industrial particulate accumulation from the Texas City complex: Homes in La Marque sit directly in the air path from one of the densest concentrations of refineries and chemical plants in the United States. Duct dust here tests as a compound of industrial fallout and mold, not ordinary household dust, and it accumulates faster than in inland Galveston County cities.

FAQs About Air Duct Repair in La Marque
If floodwater entered the ductwork, assume replacement is necessary until a camera inspection proves otherwise. Floodwater carries silt, sewage, and biological contaminants that embed in the duct liner. Cleaning can remove surface contamination, but water-damaged insulation and sealed-in mold colonies cannot be reliably cleaned. We run a camera through the affected sections and take moisture readings. If we find active mold inside sealed flex duct or compromised liner material, replacement is the only responsible fix. And if you’re filing an insurance claim, we’ll document what we found so the claim has a real chance of being accepted. Call (980) 447-2498 for an inspection and a straight answer.
La Marque sits at near sea level on Galveston Bay, which means some of the highest sustained relative humidity in Texas. HVAC systems here run essentially year-round, so ducts rarely experience a dry-out period. That constant moisture creates persistent conditions for mold colonization. Add in the post-Ike flood damage that was patched rather than replaced in many La Marque homes, and you get mold problems other Galveston County cities don’t see on the same scale. If you suspect mold in your ducts, call (980) 447-2498 and we’ll inspect before recommending anything.
Yes. This is a service we regularly perform for La Marque homeowners, especially those dealing with post-flood or post-storm damage. We photograph everything, take moisture readings, and run a camera through the full duct system to document what’s actually there. That documentation includes pre- and post-repair photos plus written findings, which gives your insurer a clear record of what was compromised and what we did about it. We can’t promise your claim will be approved, but we can promise your insurer gets an honest, documented assessment backed by our 365-Day Done Right Promise. For help with a claim, call (980) 447-2498.
It depends on the condition of the liner. If the duct is intact but sagging because the support straps failed, re-supporting it is a straightforward repair in the $275 to $600 range. If the liner has degraded to the point where it’s shedding insulation into your air stream, replacement is the only fix that actually solves the problem, typically $450 to $1,200 per run. The way to tell: we camera the inside of the duct and show you the liner. You’ll see it with your own eyes. Call (980) 447-2498 and we’ll schedule the inspection.
After we repair or replace your ductwork, we can install a high-efficiency filtration system rated for fine particulate from sources like refinery emissions and sulfur compounds. We work with brands including Abatement Technologies, Honeywell, and Aprilaire, and we’ll recommend the right filter media for the particulate load in your home. The reality is that La Marque homes will keep pulling in industrial air as long as they’re downwind of the Texas City complex. The solution is a filtration system that captures it before it settles in your ducts, and regular duct inspections to catch accumulation early. We’ll show you the options and give you a written price for whatever you choose.
If you need duct repair in La Marque and you want a straight answer, call (980) 447-2498.
