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 Cleaning Across La Marque
Air duct cleaning in La Marque typically runs $350 – $650 for a full residential system, and our crews schedule most jobs within a week. If you’re catching a petroleum odor when the HVAC kicks on, you’re not imagining it. La Marque sits directly downwind of the Texas City Industrial Complex, and that grey-black refinery film collects in return plenums and blower compartments in ways standard vacuuming often misses.
We’ve been dispatching to La Marque from our Houston office long enough to know the difference between a dusty duct and one coated in industrial fallout. Our Air Duct Cleaning team carries Rotobrush rotary systems and Nikro negative-air machines, and every technician works under The Garrison Standard: arrive inside the window, price in writing before touching anything, leave the site clean.

Why Hollis Air Duct Cleaning Is La Marque’s Preferred Air Duct Cleaning Company
La Marque homeowners have plenty of options between Houston and Galveston, but most have also dealt with the bait-and-switch routine: a coupon price that doubles once the van is in the driveway. We don’t operate that way. The price is written down before any work starts, and it does not move at the door.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week, not a callback queue that dumps you to voicemail on a Saturday afternoon.
Every job carries the 365-Day Done Right Promise in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
We know La Marque’s housing stock: the 1950s – 1970s ranch homes with original galvanized ductwork that was never sealed, the newer Columbia Memorial Parkway-area builds with flex duct that traps sticky industrial particulate, and the post-Hurricane Ike flood damage that still shows up in duct runs near bayous and low spots. That local knowledge changes what we look for and how we clean it.
Vent Cleaning in La Marque
Vent Cleaning in La Marque starts with understanding what kind of vent we’re dealing with and what’s coming through it. Supply vents push conditioned air into your rooms; return vents pull air back to the handler. In La Marque, return vents near the Texas City corridor often show that telltale grey-black film on the grille fins, and wiping the surface doesn’t touch what’s built up inside the boot and branch line. A proper vent cleaning removes the register, cleans the boot, and agitates the branch duct, not just a surface wipe. Typical vent cleaning as part of a full system runs $350 – $650; isolated vent-only service in La Marque starts around $150 – $250 depending on access and contamination level.
Supply Vent Restoration
Supply vents in older La Marque ranches often have rust staining around the screw holes and a layer of fine dust baked onto the grille by years of airflow. We remove each register, clean the boot with HEPA-contained vacuums, and inspect for disconnected flex duct behind the wall. Reconnected ducts get sealed with mastic, not tape that will fail in the humidity.
Return Vent Deep Clean
Return vents are the intake point for everything in your air. In La Marque, that includes the fine petrochemical particulate that slips past standard filters. We clean the grille, the boot, and the first several feet of branch line, then check whether the filter rack is sealed properly. An unsealed filter bypass lets dirty air straight into the blower, no matter how good your filter claims to be.
Air Duct Repair in La Marque
Air Duct Repair in La Marque is often the real fix behind a “duct cleaning” call. Much of the city’s housing stock is original galvanized sheet metal from the 1950s – 1970s, and that metal rusts from the inside out, especially where condensation collects in our Gulf Coast humidity. Seams separate, trunk lines sag, and disconnected flex duct behind walls blows conditioned air into the attic or crawl space. Repair costs in La Marque typically run $200 – $500 for minor seam sealing and reconnection, $500 – $1,200 for partial trunk replacement or extensive rust remediation. We always inspect with a camera before quoting, so you see what we see.
Galvanized Duct Sealing and Restoration
Original galvanized ductwork in La Marque’s older neighborhoods wasn’t designed to handle modern HVAC airflow rates, and the seams were never sealed to today’s standards. We apply duct sealing mastic to every accessible joint and recommend trunk replacement where rust has compromised structural integrity. Sealed ducts also cut energy waste; many La Marque homeowners see utility relief after this work.
Flex Duct Replacement
Newer La Marque homes, especially near Columbia Memorial Parkway, use flex duct that degrades faster in our humidity and traps industrial particulate in its corrugated interior. When flex duct is crushed, kinked, or internally coated with oily buildup, cleaning won’t restore it. We replace damaged runs with properly sized, insulated flex and seal all connections with mechanical fasteners and mastic.
Trusted Brands We Service in La Marque
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning inside branch lines, Nikro negative-air machines that maintain containment during the job, and filtration products from Honeywell and Guardsman. We don’t show up with a shop vac and a prayer. The Rotobrush system scrubs duct walls while simultaneous vacuum extraction pulls debris into a HEPA-filtered collector. Nikro negative-air units create suction at the access point so nothing escapes into your living space during cleaning. For homeowners in La Marque dealing with that persistent refinery odor, we can recommend and install upgraded filtration from Guardsman or Honeywell that captures smaller particulate than standard throwaway filters. Parts and filters are stocked for fast turnaround, not a two-week order delay.
Common Air Duct Cleaning Problems We See in La Marque Homes
- Refinery fallout coating blower wheels and return plenums. La Marque’s position downwind of the Texas City Industrial Complex means fine petrochemical particulate settles in HVAC systems year-round. Standard duct cleaning that skips the blower compartment leaves the source of the odor untouched.
- Rust bloom inside original galvanized ductwork. The 1950s – 1970s ranch homes that make up much of La Marque’s housing stock have unsealed metal ducts that condense moisture from our Gulf Coast air. Internal rust flakes off and circulates as orange-brown dust from vents.
- Post-flood biological growth in duct runs. Hurricane Ike in 2008 and subsequent flood events left many La Marque homes with ductwork that took on water. Even after drying, residual contamination in insulation-lined ducts can harbor microbial growth that vacuuming alone won’t address.
- Flex duct trapping sticky industrial particulate. The corrugated interior of flex duct in newer La Marque subdivisions acts like a filter for the oily, sticky fallout from refinery operations. Once coated, it resists standard brushing and may need replacement rather than cleaning.
Pricing for Air Duct Cleaning in La Marque, TX
Full residential air duct cleaning in La Marque runs $350 – $650 for a typical single-story home up to about 2,500 square feet. Two-story homes or systems with more than 12 supply vents fall toward the upper end. Commercial systems start around $800 and scale with square footage and access complexity.
What moves the price: the number of supply and return vents, whether the blower compartment and coil need cleaning (they usually do in La Marque), accessibility of the main trunk in attic or crawl space, and whether we find disconnected or damaged ductwork that needs repair before cleaning is worthwhile. We do not quote per-vent pricing. One flat price per system, agreed in writing before work starts.
Every estimate is free. We inspect the system with a camera, show you what we find, and give you a written price. No teaser coupon that balloons at the door. Call (361) 326-5060 to schedule.

FAQs About Air Duct Cleaning in La Marque
Because the previous cleaning probably skipped the blower wheel and return plenum, which is where the grey-black refinery film actually collects. In La Marque, that Texas City stack fallout is oily and fine enough to pass through standard filters, then it sticks to the blower and plenum surfaces. A proper cleaning removes and cleans those components with agitation and HEPA extraction, not just a vacuum down the vents. Call (361) 326-5060 and we’ll show you exactly what’s in your handler with a camera before we quote.
If the duct insulation got wet, vacuuming won’t address residual microbial contamination. We inspect with a scope first. Where we find water-stained insulation or active growth, we recommend removing the affected duct material and replacing it, then cleaning the remaining metal trunk. Fogging sanitiser alone doesn’t remove the source. Call (361) 326-5060 for a free inspection.
The corrugated interior of flex duct traps the sticky, oily particulate from refinery operations more aggressively than smooth metal duct. Once that film builds up, it attracts dust and resists standard brushing. Homes in that area often need more thorough agitation or earlier replacement of flex runs. We assess with a camera and tell you whether cleaning or replacement is the better value. Call (361) 326-5060 to schedule.
Look for rust staining around vent screws, hot or cold rooms that never balance, whistling from seams, or dust that returns quickly after cleaning. Original galvanized ductwork in La Marque’s mid-century ranches often has separated seams and internal rust that circulates particulate no matter how often you change filters. We camera-inspect the trunk lines to show you the actual condition. Call (361) 326-5060 for a free estimate.
No. Fogging kills surface microbes but does nothing about the sticky petrochemical fallout or the condensation that supports regrowth in our Gulf Coast climate. Source removal – physical agitation and vacuum extraction of contaminants, plus sealing leaks that draw humid unconditioned air – is what lasts. We don’t sell fogging as a substitute for proper cleaning. Call (361) 326-5060 and we’ll explain what your specific system actually needs.
