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 Air Duct Repair Across Kemah
Air duct repair in Kemah typically runs between $300 and $950 depending on whether we’re replacing a crushed flex run, resealing a rusted plenum, or repairing a disconnected branch line. Most repairs in Kemah take half a day once we locate the problem, and we stock the common parts for the area’s older elevated homes so you’re not waiting on a shipment. If you live off Bradford Avenue, along the canal streets, or in the Clear Lake Shores area, you’re dealing with salt air and humidity that inland homes simply don’t face. Call us at (980) 447-2498 and we’ll schedule a diagnostic visit that gives you a written price before any work begins.
Why Linden Air Duct Cleaning Is Kemah’s Preferred Air Duct Repair Company
We know Kemah’s housing stock because we’ve been crawling under it. The pier-and-beam cottages and stilt homes built from the 1970s through the 1990s have a specific failure pattern: flex duct runs sagging beneath floor decking, pooling condensate, and rusting metal collars from bay air. Marcus Veale, who leads our team, trains every technician to inspect the undercarriage first on elevated Kemah homes, because that’s where the real problems hide. We don’t guess at what’s wrong. We camera-inspect the ductwork, show you what we found, and give you a written price before any repair starts. Every technician who comes to your door in Kemah is background-checked, identity-verified, and photo-badged under the Threshold Standard. You get the tech’s name and photo before the visit.
We’ve earned a strong local reputation in Kemah and the surrounding bay communities by doing exactly what we say we’ll do. When a repair is finished, you get a written guarantee, and if a covered repair fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s not a slogan. It’s the standing commitment behind every job we do in Kemah.
Air Duct Replacement in Kemah
Air Duct Replacement in Kemah usually means pulling out flex duct that salt-laden moisture has degraded beyond repair and installing new, properly supported runs sealed with mastic at every connection. In older stilt homes along Galveston Bay, we commonly find entire supply branches rusted through at the collar, insulation inside the liner wicking moisture from the unconditioned air beneath the floor decking. A full replacement of one branch line in an average Kemah home runs $450 to $900, while replacing multiple supply runs in a larger elevated home can reach $1,200 to $2,000 depending on access and length. We give you that number in writing before we cut anything out.
When Replacement Beats Another Patch
If a flex run has sagged and pooled condensate for years, the insulation inside is saturated. Patching the exterior does nothing for the mold growing inside the liner. On Kemah’s canal-front lots, where humidity sits near 100% for months, we recommend replacement whenever the inner liner shows visible moisture staining or microbial growth. That’s the only repair that actually solves the problem.
Materials That Hold Up Near the Bay
We stock flex duct, metal collars, dampers, and mastic sealant sized for the older systems common in Kemah’s waterfront housing stock. Using the right materials matters here more than inland. A standard metal collar will rust through in a few years of salt air; we use components and sealants designed to resist exactly the conditions your home faces every day off Galveston Bay.
Ductwork Repair in Kemah
Ductwork Repair in Kemah often starts with a complaint that sounds vague: weak airflow in one back bedroom, a musty smell when the AC kicks on, or dust settling on furniture within days of cleaning. We trace the problem with a camera inspection, and in Kemah’s elevated homes, the answer is frequently a disconnected or crushed flex run in the unconditioned undercarriage. Repairing a single disconnected branch line typically costs $300 to $600 in Kemah. Resealing a rusted plenum or replacing multiple damaged register boots runs higher, generally $500 to $950 depending on how much of the metal has corroded from the salt-laden air. Every repair receives a written guarantee, and if the repair fails within 365 days, we return and fix it at no cost.
Sealing the Real Source of the Problem
A duct that came apart at the collar doesn’t just need reconnecting. It needs the joint cleaned, properly fitted, and sealed with mastic so the next season of bay humidity doesn’t pull it apart again. On Kemah homes with open under-floor spaces, we also inspect the support straps. Sagging flex duct is almost always a support failure as much as a material failure.
Duct Repairs and Existing Insulation
When we repair ductwork under a Kemah stilt home, we check the insulation wrap on every run we touch. Salt moisture wicks through damaged outer liners and saturates the insulation, which then holds moisture against the inner core. That’s the mold incubator you can’t fix with a filter change. If the insulation is compromised, we tell you plainly and quote the replacement as part of the repair.
Trusted Brands We Service in Kemah
We repair and replace ductwork from every major manufacturer, and we carry professional-grade equipment from Rotobrush and Nikro for the cleaning and inspection work that goes alongside repair. When your Kemah home needs air-quality components to support the repaired system, we work with products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. Because we serve Kemah regularly and know the common duct sizes and materials in the area’s older homes, we keep the frequently needed parts on our trucks, which means fewer return trips and less time with your system down.
Common Air Duct Repair Problems We See in Kemah Homes
- Disconnected flex runs beneath stilt homes. The cleats and straps holding flex duct in the unconditioned undercarriage let go over time, and the run separates from the plenum or branch collar. Air that should reach your back bedrooms is blowing into the spiders instead.
- Rusted metal collars and register boots. Salt-laden moisture from Galveston Bay corrodes the galvanized metal at every connection point. We routinely find collars in Kemah homes so rusted we can push a finger through them.
- Condensate pooling inside sagging flex duct. When flex runs lose support, they dip, and the dip collects water. In Kemah’s near-100% humidity, that water never dries out. It soaks the liner, feeds mold, and fragments the insulation.
- Post-Harvey residual moisture and sediment. Homes repaired after Hurricane Harvey often had ductwork that looked fine from the outside but retained moisture and silt that standard restoration work never addressed. That concealed contamination keeps causing microbial growth years later.
Pricing for Air Duct Repair in Kemah, TX
A straightforward duct repair in Kemah, like reconnecting a separated branch line, runs $300 to $600. Replacing a crushed or mold-saturated flex run costs $450 to $900 per branch. Full duct replacement in a larger elevated home can reach $2,000. What changes the price is access: easier access beneath a low pier-and-beam home costs less in labor than a tight stilt crawl with limited clearance. We give you one written price for the whole repair before any work starts, and that number does not change unless we find something you approve first.

FAQs About Air Duct Repair in Kemah
Your Kemah home sits directly on Galveston Bay, which means salt-laden moisture attacks the metal collars, dampers, and register boots in your duct system far more aggressively than a few miles inland in League City. The near-100% relative humidity also means condensation collects inside duct liners year-round, rusting metal and wicking into insulation. That combination degrades ductwork faster than the same materials would fail in League City or Webster. If your system is original to a 1970s-1990s elevated cottage, it’s likely at the end of its service life. Call (980) 447-2498 and we’ll camera-inspect what’s actually failing.
For an older elevated cottage in Kemah, a duct repair typically involves camera inspection of the under-floor ductwork, reconnecting or replacing damaged flex runs, sealing every joint with mastic, and replacing any rusted collars or boots. We start by accessing the undercarriage beneath the floor decking, which is where most problems in Kemah’s stilt homes actually live. The repair usually takes half a day and includes a written guarantee. If you want to know exactly what your cottage needs, call (980) 447-2498 for a diagnostic visit and a written price.
Yes, and we see it regularly. Post-Harvey remediation in Kemah often focused on drywall, flooring, and visible mold, while flex duct in unconditioned under-floor spaces was either overlooked or inadequately addressed. Residual moisture and sediment trapped inside duct liners keeps feeding microbial growth years after the rebuild. If you notice a musty smell when the AC runs or your family has persistent respiratory irritation, the ducts are a likely source. We can camera-inspect and tell you exactly what’s inside.
Salt air from Galveston Bay accelerates corrosion on every exposed metal component in your duct system: collars, dampers, register boots, and the screws holding them together. The salt acts as an electrolyte in the humid air, which means galvanized metal that would last decades in Houston rusts through in a fraction of that time in Kemah. Once a collar rusts through, the duct separates, and you lose airflow to parts of the house. We replace corroded components with materials better suited to the bay environment.
In most Kemah stilt homes, yes, because the ductwork runs through the open or semi-open undercarriage beneath the floor decking rather than through enclosed chases inside the walls. That means we can access, repair, and replace duct runs from below without disturbing your flooring or living spaces. Some homes have retrofit ductwork that is harder to reach, but the majority of repairs on elevated Kemah homes are done entirely from underneath. We’ll tell you exactly how we’ll access the work before anything starts, and the price is in writing first.
