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 Galveston
Air duct cleaning in Galveston typically runs $350 – $650 for a full residential system, and every Hollis job starts with a written price before we touch your equipment. We’re the Galveston crew homeowners call when they need ducts cleaned right after a storm, when they smell must coming through the vents, or when they’re done guessing what got left behind in their crawlspace. Dispatch and scheduling are coordinated from our Dallas-Fort Worth office, but our technicians live and work this island. They know the difference between a 1920s raised pier-and-beam in the East End and a post-Ike slab rebuild on the West End, and they know what saltwater does to galvanized steel over fifteen years. Call (361) 326-5060 and you’ll reach a live person, not a voicemail loop.
Why Hollis Air Duct Cleaning Is Galveston’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and that track record matters on an island where contractors come and go with every hurricane season. Our technicians are background-checked, uniformed, and expected to show up inside the quoted window, price the job in writing, and leave the site clean. That’s The Garrison Code, not a slogan.
Galveston homeowners don’t need another outfit that quotes low and invoices high. Our 365-Day Done Right Promise means if the work fails within a year, we come back and make it right at no charge, including a free second visit. The price we write down before we start is the price you pay. No per-vent add-ons, no equipment surcharges at the door.
Our phones are answered by a live person 24 hours a day, 7 days a week. When you’re dealing with post-storm mold or an insurance adjuster who wants documentation by morning, you don’t have time to wait until Monday.
Air Duct Inspection in Galveston
Air Duct Inspection in Galveston is where we separate cleanable ducts from ones that need full replacement, and that distinction can save or cost you thousands when you’re filing an insurance claim. Our technician runs a camera through your supply and return lines, checks moisture levels at each register, and documents rust, mold, or standing water with photos and readings. A typical inspection in Galveston runs $150 – $250, and we apply that fee toward your cleaning if you move forward.
Post-Storm Damage Assessment
After Hurricane Ike in 2008, thousands of Galveston homes got new flex duct installed fast. That flex duct degrades from the inside when moisture gets trapped. Our camera inspection finds the damage insurance can’t see from the attic hatch.
Insurance Documentation
We format our inspection reports for adjuster review: dated photos, moisture percentage readings, EPA-registered disinfectant lot numbers, and a clear statement of whether cleaning or replacement is indicated. Insurers reject undocumented claims. We don’t give them reason to.
Residential Air Duct Cleaning in Galveston
Residential Air Duct Cleaning in Galveston means more than vacuuming dust. Our rotary brush system from Rotobrush agitates debris loose from duct walls while our Nikro negative-air machine maintains suction so nothing escapes into your living space. We follow with EPA-registered disinfectant treatment, critical on an island where 70%+ humidity lets mold spores re-colonize within days. A full residential cleaning in Galveston typically runs $350 – $650 depending on system size and access.
Victorian and Historic Home Expertise
Raised pier-and-beam homes in the East End Historic District often have original galvanized steel ducts running through crawlspaces that flood in every major storm. We clean what we can, replace what we must, and document every decision.
Post-Ike Flex Duct Care
Flex duct installed after 2008 tears internally where homeowners can’t see. Our camera finds the damage before we quote cleaning, so you’re not paying to clean ductwork that belongs in a dumpster.
Trusted Brands We Service in Galveston
Our equipment roster includes Nikro negative-air machines, Rotobrush rotary brush systems, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use in hospitals and schools, not hardware-store attachments. We stock Honeywell and Aprilaire filtration media locally, so when your Galveston home needs a filter upgrade after cleaning, we install it same visit. No waiting on a parts truck from Houston.
Common Air Duct Cleaning Problems We See in Galveston Homes
- Saltwater corrosion in galvanized steel ducts. Galveston’s salt-laden air eats metal from the inside. We find rust flakes in ducts that haven’t flooded in years, and we document the corrosion pattern so insurers understand it’s environmental, not neglect.
- Black mold colonies after storm surge. Hurricane Ike pushed water through systems that homeowners thought were dry. Vacuuming alone spreads spores; our EPA-registered disinfectant treatment kills them, and our documentation proves it for claims.
- Rodent intrusion in crawlspace ducts of raised homes. Pier-and-beam construction in neighborhoods like the East End gives rats and squirrels direct access. We clean the ducts, seal the entry points we can reach, and show you photos of what we found.
- Condensation damage in flex duct from Ike-era repairs. Flex duct traps moisture against its inner liner. In Galveston’s humidity, that liner delaminates and harbors mold. Camera inspection finds it before we waste your money cleaning something that needs replacement.

Larger homes with multiple zones, commercial systems, or severe contamination from flood damage run $700 – $1,200+.

FAQs About Air Duct Cleaning in Galveston
Galvanized steel ducts with surface rust and no perforation can usually be cleaned, treated with EPA-registered disinfectant, and returned to service. Flex duct or heavily perforated metal that has held standing water needs replacement; cleaning won’t restore structural integrity or eliminate trapped salt. We document the distinction with photos and moisture readings so your insurer accepts the call. Call (361) 326-5060 for an inspection.
Galveston’s 70%+ year-round humidity means condensation inside ducts is constant, not seasonal. Mold can establish within 48 hours of moisture intrusion. Most inland Texas cities recommend cleaning every 3 – 5 years; on this island, we see meaningful buildup in 2 – 3 years, and post-flood systems need immediate assessment. Call (361) 326-5060 to schedule.
FEMA protocol requires that flood-impacted ductwork be either replaced or cleaned with EPA-registered disinfectants and independently documented, not just vacuumed. We follow this protocol on every post-storm job, produce the documentation adjusters expect, and format reports for direct submission. Call (361) 326-5060 if you’re filing a claim.
Yes. Raised pier-and-beam homes in Galveston’s historic districts have some of the most vulnerable ductwork on the island: original galvanized steel running through crawlspaces that flood, attract rodents, and collect condensation. We use portable HEPA containment, agitation tools sized for tight spaces, and document corrosion patterns for insurance. Call (361) 326-5060 to discuss access at your property.
Negative pressure contains mold spores, rust particles, and salt residue so they don’t escape into your home during cleaning. In Galveston’s humid environment, where mold colonies are often active, this containment protects your indoor air quality and your technician’s safety. Our Nikro negative-air machines maintain this containment throughout the job. Call (361) 326-5060 for details.
We were called to a raised Victorian on the East End after a homeowner noticed a musty smell and rust dust around the registers. Our tech ran a camera inspection through the original galvanized supply and return ducts, finding saltwater corrosion and black mold colonies from the Ike storm surge – so we set up negative pressure with HEPA filtration, used agitation tools to break loose the rust and mold, and treated the system with an EPA-registered disinfectant. We documented every step with photos and moisture readings, and the homeowner’s insurer accepted the claim without pushback.
In Galveston’s East End Historic District, air duct cleaning often means pulling rust flakes and mold colonies left behind by the 1900 Hurricane and the 2008 Ike storm surge, so techs must use EPA-registered disinfectants and document the work for insurance claims – a step inland Texas cities never require.
Vacuuming alone without EPA-registered disinfectant leaves mold spores that re-colonize when Galveston’s 70%+ humidity returns. Ignoring crawlspace ducts in raised pier-and-beam homes lets rodent intrusion and condensation go untreated, so rust and mold spread to the air handler. Cleaning flex duct installed during Ike repairs without camera inspection misses internal moisture damage that requires replacement, not cleaning – insurers reject undocumented claims.
Ready to get your Galveston home’s ducts inspected or cleaned? Call (361) 326-5060 for a free estimate. We’ll give you a written price before any work starts, and every job is backed by our 365-Day Done Right Promise.
