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 New Braunfels: What to Know First
We provide independent Rotobrush duct repair and sealing in New Braunfels, with most jobs scheduled within a few business days and completed in a single visit. Every repair starts with a written price before any work begins - Haven Standard Clause 1 - and ends with a documented photo record of every duct run we touched. Typical Rotobrush duct sealing jobs in this market run $340-$780 depending on system size and accessibility, while flex duct repairs range $180-$450 per run.
This page is for homeowners in New Braunfels who own a Rotobrush air duct cleaning system or have Rotobrush-branded ductwork components and need repair, sealing, or leak remediation. If you’re seeing uneven airflow, rising energy bills, or dust escaping from joints, call us at (830) 549-6847. We’ll send a written estimate, not a verbal guess.
How Rotobrush Products Fail - and How We Fix Them
- Beast series vacuum hose collar fatigue. The Beast 400 and 500 series use a proprietary collar fitting at the main trunk connection that cycles through heating and cooling seasons in New Braunfels - summer attic temperatures here regularly hit 140°F. After three to four years, the collar hardens and micro-cracks, creating a leak path that bypasses the filter entirely. We replace with an OEM-spec collar or a cross-compatible silicone-reinforced fitting rated for Comal County temperature swings, then pressure-test the joint.
- BrushBeast drive cable housing separation. The BrushBeast’s flexible drive cable runs through a plastic housing that can separate at the seam where the handle meets the wand. This doesn’t stop the brush from spinning, but it vents negative pressure (the suction that pulls debris back to the vacuum) into the attic or crawl space instead of the collection bag. We reseat the housing with mastic sealant rated for HVAC negative-pressure systems, or replace the housing if the seam is warped beyond recovery.
- Rotobrush duct adapter gasket compression set. The round-to-rectangular adapters that connect Rotobrush equipment to standard residential ductwork rely on a foam gasket that compresses permanently over time. In New Braunfels, we see this accelerated in homes near the Guadalupe River where humidity stays elevated through October. The gasket loses its seal, and the adapter rattles loose during operation. We machine-fit a replacement gasket from closed-cell neoprene stock and verify the seal with a smoke pencil - no guesswork.
- Flex duct inner liner collapse at Rotobrush connection points. The aggressive suction of the Beast series can pull the inner liner of older flex duct away from its wire helix, especially at the plenum connection - the main distribution box where conditioned air splits to each room. This creates a flapper valve effect: air moves one direction but not the other, and the duct run effectively becomes a dead leg. We cut back to sound liner, install a mechanical collar with draw bands, and seal with UL 181B-FX tape under mastic.
- Rotobrush trunk line saddle tap leaks. Some New Braunfels homes from the 2005-2015 building boom have Rotobrush-compatible saddle taps installed as original equipment - small fittings that pierce the main trunk to add a duct run without cutting the full circumference. The gasket on these taps degrades predictably after eight to ten years. We remove the tap, inspect the trunk wall for fatigue cracking, and reinstall with a welded collar or a properly sized takeoff fitting depending on what the metal condition allows.
Our Rotobrush Duct Repair & Sealing Process
- 1
Inspection with photo documentation. We run a borescope camera through every accessible duct run and photograph the condition at each joint, tap, and transition. Tomas Reyes started this practice after learning the trade at BOCES Westchester - show the photo first, explain what you’re looking at, then talk about what happens next.
- 2
Written scope and price. Before any panel comes off, you receive a written price for the exact work documented in the photos. Haven Standard Clause 1: no verbal estimates, no range that widens once the truck is parked.
- 3
Parts decision: OEM or quality aftermarket. For Rotobrush equipment, we source OEM collars, gaskets, and housings when available. When Rotobrush backorders a part - the Beast 500 collar was on six-week lead time through late 2024 - we specify the aftermarket equivalent by manufacturer and rating, and we note the substitution in writing on your job record.
- 4
Repair and seal. We execute the repair with mastic sealant, mechanical fasteners, or replacement components as scoped. Every sealed joint is marked with the date and technician initials for future reference.
- 5
Pressure verification and photo closeout. We verify seal integrity with a manometer reading or smoke test, then photograph the completed work. The before-and-after photo record is delivered as part of your standard job documentation.
- 6
Written guarantee activation. The 365-Day Done Right Promise goes into effect the moment we leave. If the repair fails, we return and make it right - backed in writing, not subject to manager discretion.

FAQs
No - duct repair and sealing performed by an independent service provider does not void Rotobrush’s equipment warranty, which covers manufacturing defects, not installation or maintenance. We are an independent Rotobrush service provider, not an authorized dealer, and we document every repair with photos and parts specifications so warranty claims on defective components remain clean. If you’re unsure whether a specific part is under warranty, we can photograph the serial plate and help you read the coverage terms.
Most single-run repairs or collar replacements are completed in two to four hours. Whole-system sealing on a larger New Braunfels home - common in the Oak Run or Meyer Ranch developments - may take a full day. We schedule the job with a realistic window and update you if the scope changes after inspection. Call (830) 549-6847 to check availability.
Repair is the right choice when the trunk line is sound and the failure is isolated to collars, gaskets, or single flex runs. Replacement becomes worth considering when the inner liner is degraded across multiple runs, the plenum itself is rusted through, or the system is original to a 1980s home in the Gruene area where flex duct technology was transitional. We’ll show you the inspection photos and give you both options in writing.
We carry cross-compatible parts for the Hawk, Beast 400, Beast 500, and BrushBeast series. For discontinued models, we machine-fit quality aftermarket components and note the specifications in your job record. If an OEM part is on backorder - which happened with the Beast 500 collar through late 2024 - we’ll tell you the lead time and the aftermarket alternative, both in writing, before you decide.
You receive a documented photo record of every duct run we touched, before and after, as a standard deliverable on every job. We also provide manometer readings or smoke-test documentation for sealed joints. If you want to verify independently, hold a tissue near a sealed joint while the system runs - no flutter means no leak. Call (830) 549-6847 if you have questions after we leave; the 365-Day Done Right Promise covers follow-up verification at no charge.
