Rotobrush Dryer Vent Cleaning in Houston: What to Know First
Rotobrush dryer vent cleaning in Houston typically costs between $129 and $229 for a single vent on a standard one-story home, and most jobs are completed in about an hour. We are an independent Rotobrush service provider – not affiliated with or authorized by Rotobrush – and we service the full range of Rotobrush vent configurations found in Houston homes, from simple straight runs to multi-story vertical stacks. The price we quote before we start is the price you pay. If you own Rotobrush equipment and need the vent it runs on cleaned, inspected, or repaired, call (713) 936-5800. Roy Castellanos and our Houston crew have kept Rotobrush dryer vent systems moving air properly for over a decade.
This page is written for Houston homeowners who already own Rotobrush dryer vent components – or who have a Rotobrush system installed and want to understand what it takes to keep it running clean and safe. We’ll cover the failure modes we see most often, what a proper cleaning looks like, and what you should expect to pay.
Key Takeaways
- Rotobrush dryer vent cleaning in Houston runs $129 – $229 for most single-vent homes; longer runs and multi-story setups cost more.

- We are an independent Rotobrush service provider. We use Rotobrush tools and our own disciplined process, but we are not a Rotobrush franchise.

How Rotobrush Products Fail – and How We Fix Them
Rotobrush makes solid equipment. The brand’s rotary brush systems are used by commercial duct crews nationwide. But in Houston – where summer humidity sits over 90% and dryers run year-round – we see the same Rotobrush-specific failure patterns repeat themselves. Here are the five most common ones we fix, and what’s actually going on when they happen.
- Rotobrush R2 and R4 vent cap flap failure. The exterior termination on older Rotobrush R2/R4 series installs uses a plastic flap that warps in Houston’s heat. Once it warps, it won’t seal – which means humid outdoor air gets pulled into the vent every time the dryer cycles off. The symptom is lint building up around the flap and dampness at the wall penetration. We replace these with metal flap assemblies that don’t warp, and we reseal the penetration with duct mastic.
- Interior duct joint separation on long horizontal runs. This is the Rotobrush-specific issue Houston owners call about most, and it’s one you won’t find in Rotobrush’s own literature. Rotobrush wall-mounted booster systems put slight positive pressure on the entire dryer duct run. If the original install used foil tape instead of mechanical fasteners at the joints, that pressure slowly pushes the joints apart – and humid Houston air condenses inside the gap. The fix is reconnecting with sheet metal screws and sealing with mastic. We see this constantly in older homes in Memorial and Bellaire.
- Lint accumulation at the Rotobrush transition elbow. Right where the flexible transition hose meets the rigid Rotobrush duct is where lint likes to pack in. The geometry of that elbow changes the airflow just enough to create a dead zone. When we clean these systems, we don’t just run a brush from end to end – we pull the transition and clean the elbow directly. It’s the difference between a vent that looks clean and one that actually is.
- Booster fan bearing wear in multi-story Rotobrush runs. Rotobrush inline booster fans are workhorses, but in three-story Houston townhomes the fan runs constantly during dryer cycles and the bearings eventually fatigue. The symptom is a whirring or grinding noise that gets louder as the dryer heats up. We replace bearings with OEM or high-grade aftermarket parts, and we always test the fan’s draw before we call the job done.
- Bird and rodent entry at damaged Rotobrush terminations. Houston’s grackles and roof rats treat a slightly damaged vent cap as an open invitation. Once they’re in, the vent becomes a fire hazard and the duct gets fouled with nesting material. We clean the full run, install bird guards with the proper mesh size, and replace the cap. This isn’t cosmetic work – a blocked vent is a fire risk.
Our Rotobrush Dryer Vent Cleaning Process
Here’s what a Rotobrush dryer vent cleaning looks like when we do it – from the first phone call to the moment we leave your driveway. No surprises, no shortcuts, no moving targets.
- 1
Call and quote. You call (713) 936-5800, talk to a live person, and tell us about your home and dryer setup. We give you a written price range before we ever schedule the visit. That number doesn’t change at the door.
- 2
Visual inspection of the full run. Our technician arrives inside the quoted window, introduces themselves, and walks the entire vent path – from the back of the dryer to the exterior termination. We check for the Rotobrush-specific issues listed above: flap integrity, joint separation, transition clogging, booster fan condition, and pest entry.
- 3
Rotobrush rotary cleaning with negative air. We connect our Rotobrush rotary brush system at the dryer end and run it through the full duct, while simultaneously pulling negative pressure with a Nikro HEPA-filtered machine. That means lint gets pulled out of your home, not blown into it. This is the same approach commercial crews use.
- 4
Component replacement, when needed. If we find a bad cap, a warped flap, or a failing booster bearing, we show you the problem and give you a written price for the fix before touching a screwdriver. We use OEM Rotobrush parts or high-grade aftermarket parts that match spec. You decide, then we do the work.
- 5
Draw test and leak check. After cleaning and any repairs, we test airflow at the termination point and check every joint seal. If it doesn’t pull air the way it should, we find out why before we leave.
- 6
Cleanup and the 365-Day Done Right Promise. The area around the dryer is left the way we found it. Every job is covered in writing – if the vent clogs again or a repair fails within one year, we return at no charge. That’s a free second visit, not a negotiated concession.

Why Houston Homeowners Call Hollis Air Duct Houston for Rotobrush Work
Most dryer vent cleaning companies in Houston can run a brush through a pipe. What they can’t do is recognize a Rotobrush transition separation before it lets humid air into your walls, or tell a failing booster bearing from a normal noise, or quote you honestly without a bait-and-switch. That’s where we separate ourselves, and it’s not by accident.
Hollis Air Duct Houston has been operating under the Garrison Partners name since 2004. We run on The Garrison Standard: arrive inside the quoted window, put the price in writing before work starts, do the job by the book, and leave the site clean. Every Rotobrush dryer vent job is covered by the 365-Day Done Right Promise – if it fails within a year, we fix it at no charge. You get a free second visit if we need to come back. Not negotiated. In writing.
Our techs are background-checked and uniformed. You know who’s walking into your home before they get there. And because we also work on systems from Lennox, Trane, and Carrier, our crew has the kind of broad HVAC knowledge that catches problems a single-brand specialist might miss. We’re not a Rotobrush franchise. We’re an independent Houston crew that knows the equipment inside and out.
FAQs
No. Using an independent service provider for dryer vent cleaning does not void a Rotobrush product warranty in the U.S. – manufacturers cannot legally require brand-only service. Our use of OEM or spec-equivalent parts on any repairs keeps your coverage intact.
Most single-vent Houston homes take about an hour from arrival to cleanup, including the draw test and inspection. Multi-story or heavily clogged vents can run 90 minutes. We tell you the expected window when you call (713) 936-5800.
Every 12 to 18 months for most Houston households. If you run the dryer daily, have pets, or live in an older home with a long duct run, plan on once a year. Houston’s high humidity means lint clings and compacts faster than it does in dry climates.
Usually yes. Our trucks carry common Rotobrush vent cap replacements, bird guards, and booster bearing kits. If you need a specialty part we don’t have on board, we’ll order it and return inside a week – and the second visit is free under our 365-Day Done Right Promise if the first visit included the cleaning.
One flat price per system, written down before work starts. We don’t itemize per vent or add door charges. The number we quote on the phone is the number on the invoice.
