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.
Rotobrush Duct Repair & Sealing in Frisco: What to Know First
We provide independent Rotobrush duct repair and sealing in Frisco, typically completing jobs in one scheduled visit with a written price delivered before any panel comes off. Most Rotobrush repairs we handle in the Frisco area run between $340 and $780 depending on whether we’re sealing accessible joints or replacing damaged flex duct runs. Haven Standard Clause 1 means the price you agree to is the price you pay, period.
This page is for homeowners who already own Rotobrush air duct cleaning equipment and have found that the machine itself can’t fix disconnected ductwork, cracked plenums, or the air leaks that keep showing up on their utility bills. If your Rotobrush unit is running but your ducts still aren’t moving air where they should, the problem is in the infrastructure, not the cleaning head. Call us at (940) 290-8552 for a free estimate with a written price.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast and BrushBeast II: cracked flex-duct connections at the main trunk. These units move serious air volume, and in Frisco’s clay-heavy soil conditions, foundation shift over time pulls flex duct away from metal trunk connections. We find this constantly in 2015-2019 builds in neighborhoods like Starwood and Phillips Creek Ranch. Our fix: cut back to solid metal, install a new collar with mastic sealant (a thick, paintable paste that hardens to an airtight finish), and support the flex run with proper strapping so the joint doesn’t take tension.
- Rotobrush aiR+ XP: collapsed return plenums in attic installations. The aiR+ XP’s higher static pressure exposes weak plenum construction. In Frisco’s summer attic heat, unsupported fiberglass board plenums sag and separate at corners. We rebuild with double-wall rigid duct or reinforced sheet metal, sealed with mastic and fiber mesh tape, not foil tape that peels after two seasons.
- Rotobrush DuctMaster and older BEAST-series: stripped brush-head couplings causing vibration damage to nearby duct runs. When the brush coupling wears, the imbalance transmits through the vacuum hose to the register boot. We’ve seen this crack the seal between drywall and metal boots in dozens of Frisco homes. We replace the coupling with OEM or quality aftermarket equivalents, then reseal the boot with fire-rated caulk and mastic.
- Rotobrush Negative Air machines: compromised filter housing seals that leak fine debris back into the duct system. The gasket material hardens in Texas heat. Debris bypasses the HEPA stage and resettles downstream. We replace the gasket with silicone-rated material, verify seal integrity with a smoke pencil (a tool that makes air leaks visible as drifting smoke), and document the before-and-after with photos.
- Rotobrush hybrid setups with third-party compressors: mismatched CFM ratings causing back-pressure on duct joints. Homeowners add aftermarket compressors without checking specs. The pressure pops mastic seals at elbows and Y-fittings. We calculate actual system static pressure, replace failed seals with rated materials, and flag any compressor mismatch in the written job record so you know before next season.
Our Rotobrush Duct Repair & Sealing Process

- 1
Call and schedule. A live person answers, confirms your Rotobrush model if you know it, and books a window. No “call for a quote” - the estimate itself is free and written.
- 2
On-site diagnostic with photo documentation. Our technician, identified by name before arrival and operating under Haven Standard Clause 3: Verified Crews, inspects every accessible duct run with a borescope camera. The photo record starts here.
- 3
Written price delivered. We show you what the camera found, explain the repair scope in plain language, and hand you a written price. Haven Standard Clause 1: no work starts until you have that number in hand.
- 4
Parts decision: OEM vs. quality aftermarket. For Rotobrush-specific components like brush couplings or filter housing gaskets, we source OEM when available. For universal items like mastic, strapping, or rigid duct, we use trade-recognized brands you can verify - Abatement Technologies for containment, Guardsman for sealants where specified.
- 5
Repair, seal, and pressure-test. We execute the repair, apply mastic or appropriate sealant, and verify with a smoke pencil or digital manometer (a device that measures air pressure differences in pascals) to confirm no measurable leakage at the repair site.
- 6
Photo record delivered, 365-Day Done Right Promise activated. Before-and-after photos of every duct run are part of your standard job record. If anything fails, we make it right - backed in writing, not subject to manager approval.

AfterWhat Rotobrush Duct Repair & Sealing Costs in Frisco
These are honest ranges for work we’ve actually performed in Frisco homes with Rotobrush equipment installed. Every job gets its own written price before work starts.
| Repair Type | Typical Range | What Moves the Price |
|---|---|---|
| Register boot reseal (1-2 boots) | $340-$480 | Attic vs. crawlspace access; drywall repair needed |
| Flex duct repair or replacement (per run) | $420-$680 | Length of run; R-value of replacement insulation |
| Plenum rebuild or reseal | $560-$780 | Fiberglass board vs. metal; number of connections |
| Full system mastic seal (accessible joints) | $680-$940 | System size; number of branch lines; accessibility |
| Return plenum reinforcement | $520-$740 | Extent of sag; need for additional support strapping |
Factors that increase cost: finished basement ceilings that need careful access, rodent damage requiring section replacement rather than sealing, and systems where previous DIY repairs used incompatible materials we must remove first. We tell you this in the written estimate, not after we’re halfway through. Call (940) 290-8552 for your exact number - estimates are free.
Why Frisco Homeowners Call CleanRun Air Duct Cleaning Frisco for Rotobrush Work

We’ve been working in Frisco since 2013, and the Starwood neighborhood in particular has taught us what foundation movement does to duct systems over time. Tomas Reyes, who leads our crews, has handled Rotobrush equipment since the original DuctMaster series. The photo is already on your phone before I say what it costs.
Our 365-Day Done Right Promise applies to every repair, not just cleaning. If a seal we applied fails within that window, we return and fix it - no re-diagnostic fee, no argument. Our technicians are background-checked and uniformed under Haven Standard Clause 3. We also service Lennox, Trane, and Carrier integrated systems when the duct issue connects to the HVAC unit itself, so you’re not coordinating two different companies.
And we publish our license number: TACLB00000000E. You can verify it with the Texas Department of Licensing and Regulation. That’s Haven Standard Clause 2: Verified Credentials.
FAQs
No - duct repair and sealing work on your home’s infrastructure does not affect Rotobrush equipment warranties, which cover the machine itself, not the building’s ductwork. We are an independent Rotobrush service provider, not authorized by Rotobrush, and we document every repair so you have a clear record of what was done to the building versus what remains factory equipment.
If your Rotobrush unit powers on and the brush spins but you’re still seeing dust accumulation near registers or uneven heating across rooms, the machine is likely working and the ducts are leaking. We verify this with a borescope inspection and static pressure test - call (940) 290-8552 to schedule.
We source OEM brush couplings, filter gaskets, and vacuum hose fittings directly when available. For universal consumables like mastic and strapping, we use trade-recognized brands - Guardsman, Abatement Technologies - that meet or exceed OEM specifications. We tell you which category each part falls into before work starts.
Replace if the ductwork is galvanized steel with widespread corrosion, if flex duct is brittle and cracking at multiple points, or if the original installation used undersized returns that can’t be modified. Repair and seal if the damage is localized and the overall layout is sound. We give you both options in writing with prices for each.
We typically schedule within 3-5 business days, sometimes sooner depending on current workload. All calls are answered by a live person who can check real availability. Call (940) 290-8552 - estimates are free and include a written price before any work begins.
