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 Dallas: What to Know First
We provide independent Rotobrush duct repair and sealing in Dallas with written upfront pricing and same-week scheduling for most calls. A typical Rotobrush repair runs $280-$620 depending on whether we’re sealing a plenum leak, patching flex duct, or rebuilding a metal trunk line connection. Every job starts with a written price before any panel comes off, and every duct run is photographed before and after.
This page is for Dallas homeowners who own a Rotobrush air duct cleaning system and have noticed weak airflow, temperature imbalances between rooms, or visible damage at duct joints. If your Rotobrush unit is working but your ducts aren’t delivering, the problem is usually in the distribution system, not the machine. Call (469) 405-6133 for a free estimate with no obligation.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush aiR+ series: cracked flex duct at the unit connection. The aiR+’s compact design puts a sharp bend right at the machine outlet, and in Dallas’s summer heat that flex hardens faster than in cooler climates. We see this on aiR+ units in Lakewood and Oak Cliff where attics hit 140°F. Our fix: replace the damaged flex section with insulated, reinforced duct rated for Texas attic temperatures, then support it so the bend radius matches manufacturer spec.
- Rotobrush Beast series: loose collar seals on the main trunk. The Beast’s higher airflow exposes weak spots in existing duct sealing, especially at plenum transitions. In North Dallas homes built 2015-2020, we often find the original mastic was thin or missed entirely. We remove the old sealant, apply new mastic rated for negative-pressure extraction systems, and pressure-test before we leave.
- Rotobrush aiR+ XP: collapsed return duct after aggressive cleaning. The XP’s brush speed can pull in lightweight flex returns if they’re not properly supported. We’ve rebuilt returns in Uptown condos where the original install used non-reinforced flex. Our fix: install a proper support strap every 4 feet and upgrade to a heavier-gauge flex or hard-pipe the critical section.
- Rotobrush commercial units: separated duct runs at register boots. Commercial Rotobrush systems move more air, and in Dallas’s older commercial buildings near the Design District, register boots were often sealed with tape that degrades. We reseat the boot, seal with mastic, and add a mechanical fastener so vibration won’t reopen the gap.
- Rotobrush aiR+ and Beast: plenum leaks causing pressure loss. Both series depend on sealed plenums to maintain suction. In Dallas’s clay-soil areas like Preston Hollow, foundation shift cracks plenum seams over time. We seal with fiberglass-reinforced mastic, then verify with a manometer reading that matches the unit’s spec sheet.
Our Rotobrush Duct Repair & Sealing Process
- 1
Inspection with photo documentation. We photograph every duct run before touching anything. Tomas Reyes started this practice in 2013, and we still deliver the photo record as a standard job deliverable.
- 2
Written price under Haven Standard Clause 1. You get one flat price per system, agreed in writing, before any work starts. No per-vent pricing, no add-ons after the truck is parked.
- 3
Parts decision: OEM or quality aftermarket. For Rotobrush-specific components like collar adapters, we source OEM when available. For generic duct materials, we use trade-recognized brands - Guardsman flex, Honeywell supports, Aprilaire mastic - so you can verify specifications independently.
- 4
Repair and seal with pressure test. We complete the repair, seal all joints, and run the Rotobrush unit to verify airflow and suction match expected performance. If numbers are off, we find the leak before we pack up.
- 5
Photo record delivery and 365-Day Done Right Promise. You receive before-and-after photos of every duct run we touched, plus the written scope and warranty. If it’s not right, we make it right - backed in writing, not subject to manager approval.
BeforeAfterWhat Rotobrush Duct Repair & Sealing Costs in Dallas
| Repair Type | Typical Range | What Affects Price |
|---|---|---|
| Single flex duct patch or replacement | $280-$420 | Length, attic accessibility, insulation grade |
| Plenum seal or rebuild | $340-$580 | Size, material (galvanized vs. fiberglass), access |
| Register boot reseat and seal | $180-$290 | Count, ceiling vs. floor, duct type |
| Full trunk line repair with mastic | $480-$620 | Linear feet, number of branches, pressure-test requirement |
Three factors move the price: how much duct we need to access, whether we’re working in a 140°F Dallas attic or a conditioned crawl space, and whether the original install used proper materials or shortcuts we need to undo. We don’t do $79 coupons that become $800 invoices. One flat price per system, agreed before work starts. Call (469) 405-6133 for an exact quote - estimates are free.

FAQs
No - duct repairs don’t touch the Rotobrush unit itself, so manufacturer warranty coverage on the machine remains intact. We are an independent Rotobrush service provider, not authorized by the manufacturer, and we document exactly what we touched so there’s no confusion if you ever need factory service on the unit. Call (469) 405-6133 if you want us to review your warranty paperwork before we start.
If your Rotobrush runs but rooms stay hot or cold, or your energy bills rose without thermostat changes, you likely have leaks or separations that cleaning won’t fix. We inspect first and show you the photo evidence before recommending repair. Call (469) 405-6133 for a free inspection.
We source OEM Rotobrush components like collar adapters and connection hardware when they’re available through standard distribution channels. For duct materials themselves - flex, mastic, supports - we use professional-grade brands you can verify: Guardsman, Honeywell, Aprilaire. We tell you which is which before we order anything.
Most single repairs finish in 2-4 hours. Full trunk line work or multiple register boots may take a full day. We give you a time estimate with the written price, so you know both numbers before we start.
Replace if the ductwork is galvanized metal with widespread corrosion, or if flex duct is brittle throughout - common in Dallas homes with original 1980s-1990s installs. Repair if damage is localized and the remaining duct is structurally sound. We’ll show you the camera footage and give you both options in writing. Call (469) 405-6133 for an honest assessment.
