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.

Call (469) 972-3151 for a free written estimate.
We’ve been serving La Marque long enough to know that ductwork here isn’t like ductwork in Katy or The Woodlands. The combination of salt-heavy Gulf air, chronic humidity, and that persistent petrochemical drift from the Texas City refinery corridor creates a specific kind of contamination that standard cleaning protocols don’t always address. Our Air Duct Cleaning team doesn’t just vacuum out dust; we inspect for the degradation patterns that are common to this specific coastal environment.
Why Kestrel Air Duct Cleaning Is La Marque’s Preferred Air Duct Cleaning Company
La Marque homeowners call us because we’ve built a reputation on showing up in the window we promised and leaving the price where we left it. The Kingswell Guarantee, which has governed every job since our founding in 2004, means a written price before any work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. No door-step revisions. No “we found something else” invoices.
Our technicians are background-checked, uniformed, and equipped with Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. These aren’t shop vacs from a big-box store. The Rotobrush dislodges debris at the duct wall through mechanical agitation. The Nikro unit maintains negative pressure so loosened contaminants get pulled out of the system rather than pushed into your living space. The Abatement Technologies HEPA filtration captures particles down to 0.3 microns. We explain what each piece does before we start, because you should know what you’re paying for.
Calls are answered by a live person, 24/7. Not an automated queue. A real conversation, any time of day. Scheduling and dispatch are coordinated from our Houston office, and crews serve La Marque locally with the equipment and supplies to complete most jobs in a single visit.
HVAC Duct Cleaning in La Marque
HVAC Duct Cleaning in La Marque means more than removing visible dust from registers. The near-constant 85-95% humidity during the April-October cooling season causes condensation to form on cool duct surfaces, and that moisture feeds biological growth inside supply and return runs that air conditioning then distributes throughout the home. A typical full HVAC duct cleaning for a La Marque home runs $450-$650, with smaller systems or partial cleanings sometimes falling to $350-$450.
Full System Source Removal
We use brush agitation followed by negative-air extraction to remove contamination from the duct wall itself, not just vacuum what’s loose. This matters in La Marque because the petrochemical residue and salt-laden air create a tacky, adhered layer that suction alone won’t dislodge. Source removal is the only method that addresses the root problem.
Post-Storm Forensic Assessment
Many La Marque homes sustained moisture intrusion during Hurricane Ike in 2008. We inspect for the telltale signs: delaminating duct liner, black staining on the interior surface, and musty odor that returns within days of standard cleaning. When we find saturated flex duct that was patched rather than replaced, we document it with photographs and written recommendations.
Vent Cleaning in La Marque
Vent Cleaning in La Marque addresses the supply and return registers, grilles, and the immediate duct runs behind them where visible dust accumulation first appears. This service typically runs $150-$275 for register and boot cleaning, or $250-$400 when combined with dryer vent cleaning. Many La Marque homeowners start here when they notice reduced airflow or visible debris around vents but aren’t sure whether full duct cleaning is warranted.
Register and Boot Deep Cleaning
We remove each register, clean the boot and first few feet of duct run with rotary brush tools, and treat for biological growth where humidity has caused staining. In La Marque’s older homes off Mainland Drive and the Highway 3 corridor, we often find that register boots are the first place post-Ike mold contamination becomes visible.
Video Inspection Before Commitment
We offer video inspection of vent-adjacent duct runs so you can see the condition before deciding on a larger scope of work. The camera doesn’t lie. If the duct beyond the boot is cleanable, we’ll say so. If it’s compromised, we’ll show you the footage and explain why replacement makes more sense than repeated cleaning.
Trusted Brands We Service in La Marque
We clean and service ductwork connected to all major HVAC brands, and we stock Honeywell and Aprilaire filtration products for La Marque homeowners who want to maintain cleaner air between professional cleanings. Guardsman air quality accessories are also available. For homes with persistent humidity issues, we can recommend and install Aprilaire whole-home dehumidification equipment that reduces the condensation that feeds mold growth in coastal duct systems. Parts and filters are carried on our service vehicles, so most upgrades happen during the same visit as your cleaning.
Common Air Duct Cleaning Problems We See in La Marque Homes
- Post-Ike patch jobs with untouched attic ducts. The drywall and insulation got replaced after 2008, but the original saturated flex duct in the attic was left in place. Mold-contaminated liner keeps cycling spores into living spaces, and homeowners wonder why they keep getting musty odors and respiratory irritation.
- Coastal humidity feeding biological growth. Condensation forms on cool supply and return surfaces during the long cooling season, creating ideal conditions for mold colonization. Routine vacuuming without source removal just skims the surface; the biological layer remains adhered to the duct wall.
- Petrochemical residue accelerating liner degradation. Salt-laden air and refinery corridor particulates create a corrosive environment where ducts that look intact from the exterior have crumbling interior surfaces. Only camera inspection reveals the true condition.
- Original 1950s-1970s flex duct reaching end of service life. The petrochemical-boom housing stock in La Marque includes thousands of homes with flex duct that has exceeded its design lifespan. The material becomes brittle, the insulation compacts, and air leakage increases while the system tries to compensate with longer run times.
Pricing for Air Duct Cleaning in La Marque, TX
Most La Marque homes fall between $450 and $550 for a complete residential air duct cleaning, with smaller single-story homes sometimes at $350-$450 and larger or heavily contaminated systems reaching $650-$750. Commercial duct cleaning starts around $800 and scales with system complexity. We give one flat price per system, agreed in writing before any work begins. No per-vent pricing. No add-ons at the door.
What moves the number: the number of supply and return runs, whether video inspection reveals compromised flex duct requiring replacement, the degree of biological contamination, and accessibility (crawl space versus attic versus basement). We take before-and-after photos of your actual ducts, not stock images. You’ll see what we removed and what the interior surface looks like after cleaning.

FAQs About Air Duct Cleaning in La Marque
It depends on the material and the duration of saturation. Metal trunk lines and hard ductboard can often be cleaned and restored with source-removal methods and antimicrobial treatment. Saturated flex duct with delaminating or blackened interior liner must be replaced; cleaning cannot restore structural integrity or remove embedded mold from porous insulation. We document the distinction with camera inspection and photographs so your insurer can see why replacement is necessary. Call (469) 972-3151 for an assessment of your specific system.
The root cause is usually unresolved moisture. La Marque’s coastal humidity, combined with air conditioning that runs almost continuously from April through October, creates condensation on cool duct surfaces that feeds new growth. If the original cleaning didn’t include source removal of the biological layer, or if saturated flex duct was left in place, the mold simply recolonizes. We address this by identifying and documenting moisture sources, replacing compromised flex runs, and recommending humidity control strategies. Call (469) 972-3151 to stop the cycle.
We provide dated, high-resolution photographs from our video inspection system showing interior duct condition, written descriptions of contamination type and extent, and a clear separation of cleanable components from those requiring replacement. We were called to a home off the Highway 3 corridor where the owners had repaired ceilings after Ike but never replaced the attic flex runs; camera inspection showed the interior liner of the supply and return ducts was black and delaminating, so we set up negative pressure with a HEPA filtration unit and used Rotobrush agitation tools, then documented the compromised sections with photos for the owners’ insurer. We replaced only the saturated flex runs and cleaned the remaining metal trunk lines, and the blower motor amp draw dropped noticeably after the airflow was restored. This documentation package has been accepted by multiple carriers. Call (469) 972-3151 to schedule an inspection.
Yes. Airborne particulates including sulfur compounds, petroleum dust, and combustion byproducts drift north from the Texas City industrial complex and combine with salt-laden Gulf moisture to create a uniquely corrosive deposit on duct surfaces. This residue is tackier and more adherent than ordinary household dust, which is why mechanical brush agitation followed by negative-air extraction is necessary for effective removal. Standard vacuum methods leave this layer largely intact. Call (469) 972-3151 for a cleaning protocol that addresses La Marque’s specific contamination profile.
Homes with original or early-generation flex duct from the 1950s-1970s should have camera inspection every 2-3 years, and sooner if you notice musty odors, visible mold around registers, or increased allergy symptoms. The combination of age, coastal humidity, and potential post-Ike saturation means these systems degrade faster than ductwork in inland suburbs. Early inspection catches compromised sections before they become health hazards or force your HVAC system to overwork. Call (469) 972-3151 to schedule; estimates are free.
