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 Johns Creek: What to Know First
We provide independent Rotobrush duct repair and sealing in Johns Creek, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. Typical Rotobrush duct sealing runs range from $340 to $780 depending on system size and access, while flex duct repairs start around $280. As an independent Rotobrush service provider - not affiliated with or authorized by the manufacturer - we work on the actual units found in Johns Creek homes, from the original BrushBeast series through the current Beast Max models. This page is for homeowners who searched their Rotobrush model number, found a duct leak or collapsed flex run, and want to know what honest repair looks like before calling anyone. Questions? Call (470) 326-1926; a live person answers.
How Rotobrush Products Fail - and How We Fix Them
- BrushBeast original series: cracked plenum collars at the main trunk connection. The ABS plastic collar on early BrushBeast units fatigues after repeated thermal cycling, especially in Johns Creek’s humid subtropical climate where attic temperatures swing 40 degrees between seasons. We replace with a galvanized steel transition collar and seal with mastic rated to 250°F, not tape that will creep in summer heat.
- Beast Max 2: internal flex duct separation at the blower outlet. The corrugated flex sleeve between the blower housing and the main duct run detaches where the clamp sits, usually because the factory clamp was overtightened and cut the jacket. We install a reinforced neoprene sleeve with a constant-tension clamp, then pressure-test to verify no bypass air.
- BrushBeast Pro: return box collapse in two-story zoned systems. The negative pressure from the high-suction Pro series pulls inward on undersized return boxes, particularly in Medlock Bridge corridor homes with secondary returns hidden behind drywall. We sister the box with 26-gauge galvanized, seal all seams with fiber-reinforced mastic, and verify structural integrity with a borescope before closing.
- All Rotobrush portable units: hose port wear causing leakage at the tool connection. The quick-connect ports on the vacuum hose wear oval after roughly 800-1,200 hours of use, creating a leak path that reduces suction and lets attic air bypass filtration. We machine a brass insert sleeve or replace the port assembly, depending on wall thickness remaining.
- Beast Max series: condensate pan overflow rotting nearby flex duct. The integrated condensate pan on Max units drains through a 3/8-inch barb that clogs with biofilm in Johns Creek’s high-humidity months; overflow soaks adjacent flex duct and collapses the insulation. We clear the drain, treat the pan with EPA-registered antimicrobial, and replace damaged duct with R-8 insulated flex, routing it above the pan’s spill line.
Our Rotobrush Duct Repair & Sealing Process
- 1
Systematic diagnostic with photo documentation. We run the Rotobrush unit and map pressure differentials across every duct run, photographing each register, trunk, and plenum junction with a borescope. The photo goes first. The price comes after.
- 2
Written scope and price under Haven Standard Clause 1. Before any repair begins, you receive a written scope naming every part and labor line, with one flat price for the complete repair. No per-vent pricing. No open-ended hourly rates.
- 3
Parts decision: OEM vs. quality aftermarket. For warranty-active units under 5 years, we source Rotobrush OEM collars and port assemblies when available. For older units, we use aftermarket parts from Guardsman and Abatement Technologies that meet or exceed OEM spec, documented in your job record.
- 4
Repair, seal, and pressure verification. We complete the mechanical repair, seal all joints with mastic or foil-backed tape per SMACNA standards, then pressurize the system to 25 Pascals and verify no leakage above 5% of design flow.
- 5
Documented Photo Record delivery and 365-Day Done Right Promise activation. You receive before-and-after photos of every duct run we touched, plus the written scope, the pressure test result, and the warranty document. If anything fails, we make it right. That’s Haven Standard Clause 5.

| Service | Typical Range | What Moves the Price |
|---|---|---|
| Single flex duct repair/replacement | $280 - $420 | Length, R-value, attic vs. crawl access |
| Plenum collar replacement (Rotobrush-specific) | $340 - $520 | Steel vs. OEM ABS, trunk size |
| Full duct sealing (mastic, per system) | $480 - $780 | Number of runs, accessibility, existing tape removal |
| Return box rebuild/reinforcement | $560 - $890 | Secondary returns, drywall repair scope |
| Condensate pan + adjacent duct replacement | $620 - $940 | Pan material, drain line reroute |
These are whole-system prices agreed in writing before work starts, not teaser rates that balloon once the truck is in your driveway. Homes near the Chattahoochee River corridor often run higher due to crawl-space moisture remediation needs.

Why Johns Creek Homeowners Call CleanRun Air Duct Cleaning Johns Creek for Rotobrush Work
We’ve serviced Rotobrush units in Johns Creek since 2013, including the two-story builds around Medlock Bridge where zoned systems hide the worst problems behind secondary returns Tomas Reyes first documented in 2019. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry the full equipment roster - Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, Guardsman - so a Rotobrush repair doesn’t stall because a part needs cross-referencing with a Lennox, Trane, or Carrier system.
Every job ends with a Documented Photo Record: the inside of every duct run, before and after, delivered as a standard deliverable, not an upsell. The 365-Day Done Right Promise is written on every invoice, not buried in a website footer. If the work is not right, we make it right.
FAQs
No - independent duct repair does not void the Rotobrush unit’s motor or blower warranty, which covers manufactured components only. The warranty does not extend to field-installed ductwork, which is your home’s infrastructure. We use warranty-safe practices for any mechanical work on the unit itself, and we document which parts are OEM versus aftermarket in your job record so warranty claims remain clean. Call (470) 326-1926 if you need help navigating a claim.
Common Rotobrush collars, port assemblies, and flex sleeves ship within 2-3 business days from regional distributors in Atlanta. For older BrushBeast series units, we sometimes machine a compatible solution same-day from Guardsman or Abatement Technologies stock rather than wait for discontinued OEM. We tell you which path we’re taking before you approve the scope.
Replace when the ductwork is galvanized steel with widespread rust perforation, or when flex duct insulation is saturated and delaminated throughout - conditions we photograph and show you. Repair when the damage is localized to collars, isolated flex runs, or seal failures. In Johns Creek’s climate, we see more repairable cases than total replacements, especially in homes built 2015-2022 with modern flex trunk systems.
We verify with a pressure test: the system is pressurized to 25 Pascals and held for 10 minutes, with leakage measured against design flow. You receive the numerical result in your Documented Photo Record. If leakage exceeds 5% post-repair, we reseal at no charge under the 365-Day Done Right Promise.
Yes. Many Johns Creek homes pair a Rotobrush air handler or cleaning port with a Lennox, Trane, or Carrier heat pump or furnace. Our technicians carry cross-reference documentation for all three brands and understand how each interfaces with Rotobrush duct geometry, particularly at the plenum transition. We do not guess at compatibility.
