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.

AfterAir Duct Cleaning Company in League City, TX
Air duct cleaning in League City typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a few business days and completed in 2 – 4 hours. We’re Hollis Air Duct Cleaning, and we’ve learned that Gulf Coast humidity, slab-on-grade construction, and flood-prone soil make League City ductwork unlike anything you’ll find inland. Our crews arrive uniformed, price the job in writing before touching your system, and back every visit with our 365-Day Done Right Promise. Call us at (361) 326-5060 for a free estimate.
Why League City Homes Are Different
League City sits on some of the most flood-prone ground in the Houston metro, and that changes everything about how we approach ductwork here. The combination of Gulf humidity, record rainfall events, and slab-on-grade subdivision construction means ducts take on water and grow mold in ways inland Texas cities rarely see. Post-flood duct cleaning and mold remediation after a major rain event isn’t an afterthought for us, it’s a League City specialty.
Most homes here are slab-on-grade subdivisions built from the 1970s through the 2010s, with the biggest construction wave in the 1990s and 2000s. Those systems run flex duct through hot, humid attics, trapping moisture and dust against the insulation. Older homes near Main Street in historic League City have smaller, tighter duct runs that need a gentler approach than the wide-open flex systems in newer master-planned communities. We adjust our equipment and technique to match.
The climate doesn’t give these systems a break. May through September, HVAC units push moist air through ductwork for hours on end, and that moisture condenses on cool metal surfaces. Add the high water table and frequent heavy rainfall, and you’ve got year-round conditions that promote microbial growth. We’ve found water lines and mold inside ducts in neighborhoods that never officially flooded, because saturated soil drives moisture up through slab penetrations and straight into the system.
Our Main League City Services
Homeowners in League City call us for three core services, each handled with The Garrison Standard of written pricing, background-checked technicians, and our 365-Day Done Right Promise.
Air Duct Cleaning in League City
We clean the full supply and return duct network using a Rotobrush rotary brush system or Nikro negative-air machine, depending on your home’s duct type and condition. In League City’s flex-duct homes, we pay special attention to attic runs where humidity has degraded the insulation lining. Every job includes before-and-after photos of your own ducts, not stock images. Air Duct Cleaning in League City
Dryer Vent Cleaning in League City
Lint buildup in dryer vents is a genuine fire hazard, and League City’s humidity makes that lint cling to pipe walls longer than it would in drier climates. We clear the full vent run from appliance to termination, check airflow with a meter, and verify the exterior cap opens fully under pressure. If your dryer takes two cycles to finish a load, the vent is almost certainly restricted. Dryer Vent Cleaning in League City
Duct Sealing in League City
League City’s expansive clay soils shift with moisture, and that movement cracks mastic seals at duct joints over time. We seal accessible leaks with duct sealing mastic and mechanical fasteners, then pressure-test to confirm the improvement. In humid attics, sealed ducts stop pulling hot, moist outside air into the system, which means your AC runs less and your indoor humidity drops. Duct Sealing in League City
