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.

AfterRotobrush Duct Repair & Sealing in Houston: What to Know First
CleanRun Air Duct Cleaning Houston provides independent Rotobrush duct repair and sealing for Houston homeowners, with most repairs completed in a single visit and a written price delivered before any work begins. We service Rotobrush air duct cleaning systems and their connected HVAC ductwork, including the popular BrushBeast series and legacy Roto-Vac models, addressing the specific failure modes these units develop in Gulf Coast conditions. This page is for Rotobrush owners in Houston who need duct sealing, flex duct repair, or metal duct repair and want a technician who knows the difference between a Rotobrush plenum connection and a standard Carrier drop. Call (346) 251-8919 for a free estimate with a written price.
How Rotobrush Products Fail - and How We Fix Them
- BrushBeast vacuum motor seal degradation. The BrushBeast’s high-suction vacuum motor creates significant negative pressure at the plenum (the main distribution box where duct runs connect), which stresses the flexible duct connections over time. In Houston’s humidity, the factory rubber gaskets harden faster than in drier climates, causing air leaks at the plenum collar. We replace these with mastic sealant (a thick, brush-applied paste that hardens into an airtight bond) rated for high-humidity environments, not just tape patches that peel within a season.
- Roto-Vac legacy hose port cracks. Older Roto-Vac units, still common in Houston homes purchased between 2015 and 2020, develop stress fractures at the hose intake port where the flexible duct meets the main body. The plastic compound used in these models becomes brittle after repeated heat cycling in unconditioned attics. We fabricate a reinforced metal sleeve insert rather than replacing the entire port assembly, which saves the customer roughly $200-$340 in parts while restoring structural integrity.
- Flex duct collapse at the Rotobrush wye connection. Rotobrush systems use a wye fitting (a Y-shaped junction that splits airflow between two duct runs) that creates a turbulence point. The lightweight flex duct (the ribbed, foil-wrapped tubing common in Houston tract homes) flattens at this junction after 3-5 years of BrushBeast operation. We install a rigid metal transition piece with a support strap to prevent recurrence, documented in the before-and-after photo record.
- Condensate line back-feed into duct runs. Houston’s 70%+ average humidity means Rotobrush units without proper duct sealing eventually draw moisture through leaks into the return duct. The BrushBeast’s aggressive airflow can pull condensate backward from the evaporator coil pan if the plenum seal is compromised. We seal the plenum with mastic and install a secondary condensate safety switch, then pressure-test the repair to verify negative-pressure integrity.
- Aftermarket filter housing misalignment. Many Houston Rotobrush owners have replaced original filter housings with generic units that don’t match the BrushBeast’s exact flange dimensions. The resulting 1/4-inch gap at the housing perimeter leaks unfiltered attic air directly into the supply duct. We measure the flange with a feeler gauge and either source an OEM-spec replacement or machine a custom gasket from closed-cell neoprene, depending on parts availability.
Our Rotobrush Duct Repair & Sealing Process
- 1
Inspection with photo documentation. We photograph every duct run before touching anything. The photo goes first. The pitch comes later, if it’s warranted.
- 2
Written price under Haven Standard Clause 1. You receive a line-item scope with exact costs before any panel comes off. No exceptions.
- 3
Parts verification. For Rotobrush-specific components, we check OEM availability against quality aftermarket alternatives and explain the trade-off in writing. Some BrushBeast seals are only available factory-direct with a 10-day lead time; we stock compatible aftermarket equivalents that meet the same pressure specifications.
- 4
Repair execution. Flex duct repair uses metal-reinforced sleeves. Metal duct repair involves cutting out damaged sections and welding or sealing with mastic. Duct insulation is replaced where Gulf Coast moisture has degraded the R-value (the measure of thermal resistance).
- 5
Pressure test and photo record delivery. We verify sealed-system integrity with a manometer reading, then deliver your documented photo record showing every duct run before and after.
- 6
365-Day Done Right Promise activation. The written guarantee is included in your job record, not a separate marketing piece.
BeforeAfterWhat Rotobrush Duct Repair & Sealing Costs in Houston
| Service | Typical Range | What Affects Price |
|---|---|---|
| Plenum seal repair (BrushBeast) | $280-$420 | Accessibility, mastic vs. full collar replacement |
| Flex duct repair, single run | $180-$340 | Length of run, attic access difficulty |
| Metal duct repair with sleeve | $340-$580 | Sheet metal gauge, welding required |
| Roto-Vac port reinforcement | $220-$380 | Crack severity, OEM vs. fabricated insert |
| Full duct sealing (mastic, whole system) | $680-$1,200 | System size, number of registers |
These are whole-system prices, not per-vent teaser rates. The final number depends on what the camera actually shows, not what we hope to sell. Call (346) 251-8919 for a free estimate with a written price.
Why Houston Homeowners Call CleanRun Air Duct Cleaning Houston for Rotobrush Work
We’ve been documenting ductwork since 2013, and the 52,000+ homes in our records include hundreds of Rotobrush systems across Houston’s Energy Corridor, Memorial, and Sugar Land. Tomas Reyes, our owner, spent years in the northeast before relocating to Houston and has a working education in how Gulf Coast humidity turns a mildly dusty duct into a debris problem faster than most homeowners expect. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so we’re not guessing when your Rotobrush connects to a mixed-brand HVAC setup. Every job ends with a documented photo record and the 365-Day Done Right Promise in writing.
FAQs
No, independent duct repair and sealing does not void your Rotobrush equipment warranty, provided the work is performed on the connected HVAC ductwork and not on the Rotobrush unit’s internal electrical components. We are an independent Rotobrush service provider, not an authorized dealer, and we document exactly which components were touched so there’s no confusion if you later need factory service. Call (346) 251-8919 if you want us to review your warranty paperwork before scheduling.
OEM BrushBeast seals and collars typically ship in 7-10 business days from Rotobrush’s Texas distribution center; we stock compatible aftermarket equivalents that meet the same pressure specifications for same-day completion. Roto-Vac legacy parts are increasingly factory-backordered, which is why we fabricate reinforced inserts in-house. We’ll tell you the lead time in writing before you commit. Call (346) 251-8919 for current parts availability.
Replace if the flex duct shows multiple collapse points, the metal duct has corrosion holes larger than a quarter, or the repair cost exceeds 60% of a new Rotobrush-compatible duct installation. Repair if the damage is localized to seals, single runs, or the plenum connection. We show you the inspection photos and both numbers in writing, then let you decide. Call (346) 251-8919 for a free second opinion on any replacement quote.
You receive a documented photo record of every duct run, before and after, plus a manometer pressure reading showing sealed-system integrity. Haven Standard Clause 1 requires written proof of every claim we make. If a technician can’t show you the photo, the work isn’t done. Call (346) 251-8919 to schedule a documented repair.
Yes, most Houston Rotobrush installations are retrofitted onto existing HVAC systems, and our technicians service the full range of connected brands. The duct repair principles are universal, but the connection details vary. Carrier systems often use a proprietary plenum adapter that requires a custom gasket; Trane units typically need additional support strapping at the flex duct transition. We name the specific equipment in your written scope before starting. Call (346) 251-8919 for an estimate.
