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.

How Nikro Products Fail - and How We Fix Them
- Nikro 860 Series Flex Duct: collar separation at the plenum connection. The 860’s mylar outer wrap tends to delaminate from the wire helix where it meets the galvanized collar, especially in Dallas attics where summer temperatures exceed 140°F and bake the adhesive. We cut back to sound material, install a mechanical draw-band with mastic sealant (not tape alone), and pressure-test the joint before closing.
- Nikro 862 Series: internal liner collapse in long horizontal runs. The 862’s fiberglass inner liner sags when support straps fail, creating a dam that collects condensation and debris. We replace the compromised section with new Nikro-compatible flex, add support every 4 feet per SMACNA guidelines, and photograph the liner condition at both ends for the job record.
- Nikro PVC-Coated Duct (commercial/residential hybrid): seam splits at factory welds. The PVC coating on Nikro’s hybrid line can mask hairline cracks in the underlying metal; we remove coating at suspect seams, dye-penetrant test, and re-seal with Nikro-compatible mastic or replace the section if the crack propagates into the wire helix.
- Nikro Quick-Connect collars: gasket hardening and air bypass. The EPDM gasket in Nikro’s quick-connect fittings degrades after 8-12 years in North Texas conditions, causing measurable leakage at the register boot. We source direct-fit replacement gaskets or machine custom seals from closed-cell neoprene when OEM stock is backordered.
- Nikro insulated flex: water intrusion from failed vapor barrier. Dallas’s spring storm season drives humidity into attic runs where the vapor barrier has been punctured by rodents or trades. We strip to bare duct, assess the wire helix for rust (common in Lakewood and M-Streets homes with cedar shingle debris), replace if pitted, and reinstall with a continuous vapor barrier sealed at every penetration.
Our Nikro Duct Repair & Sealing Process

- 1
Written estimate on arrival. We inspect accessible ductwork with a borescope camera, identify Nikro model markings, and deliver a written price before any work begins - Haven Standard Clause 1. No exceptions.
- 2
Parts verification. We confirm whether OEM Nikro components are available or if a quality aftermarket equivalent meets the same pressure and temperature specs. We document the choice in writing.
- 3
Repair execution. Our crew performs the repair using Nikro-compatible tooling - mastic rated for the specific liner type, mechanical fasteners at all joints, and support straps at code spacing.
- 4
Pressure verification. We test sealed joints with a digital manometer or smoke pencil, depending on access, and record the pre- and post-repair leakage rate.
- 5
Photo documentation and cleanup. Every duct run is photographed before and after. The images, the written scope, and the pressure test results are delivered as your standard job record - part of every CleanRun visit since 2013.
- 6
365-Day Done Right Promise activation. Your written guarantee goes into effect the moment we finish. If the repair fails, we make it right. No manager approval required.

AfterWhat Nikro Duct Repair & Sealing Costs in Dallas
These are real ranges for Nikro systems we have repaired in Dallas homes, not teaser rates:

| Nikro insulated flex replacement with vapor barrier | $480 – $920 | Run length, insulation R-value, helix rust status |
Factors that increase cost: multiple attic access points in older Dallas homes (Design District, Bishop Arts), rodent damage requiring helix replacement, or buried ductwork behind finished ceilings.

Why Dallas Homeowners Call CleanRun Air Duct Cleaning Dallas for Nikro Work

We have handled Nikro duct systems alongside Lennox, Trane, and Carrier equipment in Dallas homes since 2013. Our technicians carry model-specific parts knowledge, not generic duct tape and hope. The 365-Day Done Right Promise is backed in writing on every job, not mentioned in passing and forgotten. Background-checked, uniformed crews operate under Haven Standard Clause 3: Verified Crews, and you will know your technician’s name before the truck arrives.
Tomas Reyes, our owner, grew up in Queens and learned the trade at Suffolk County Community College before spending two decades inside residential ductwork. He runs jobs personally across Dallas, including properties near the Design District where older buildings hold dust and debris in ways newer construction does not. His habit is to show the duct first and talk about the solution second - the photo record is standard, not an upsell.
Every job includes a Documented Photo Record of every duct run, delivered as part of your standard job record. You will see what we found, what we did, and what the pressure test proved.
FAQs
No - Nikro’s warranty on duct materials covers manufacturing defects, not field repairs, so independent service does not void it. However, any replacement parts we install carry their own warranty through CleanRun’s 365-Day Done Right Promise, not through Nikro. If your system is under an HVAC installer’s labor warranty, we will review the terms with you before starting work. Call (469) 405-6133 if you need help interpreting coverage.
Repair is viable when the wire helix is intact, the liner is cleanable, and leakage is localized to joints or short sections. Replacement makes sense when multiple runs show liner collapse, widespread rust, or asbestos-containing insulation in pre-1985 homes (still found in parts of Oak Cliff and East Dallas). We photograph everything and give you both options in writing. Call (469) 405-6133 for a free inspection and written comparison.
Some Nikro OEM parts are available through HVAC supply houses with 3-10 day lead times; others have been discontinued as Nikro shifted focus toward remediation equipment. We stock quality aftermarket equivalents rated for the same pressure and temperature specs, and we document which route we take on your written scope. You will know before we start. Call (469) 405-6133 to check current parts availability for your model.
A single-register repair takes 2-3 hours; whole-system sealing on a 2,000-square-foot Dallas home takes a full day. We schedule by the job, not by the hour, so we do not rush pressure testing or photo documentation. You will receive a written completion time estimate with your upfront price. Call (469) 405-6133 to book a slot that works with your schedule.
Your job record includes before-and-after photographs of every duct run, the written scope describing what was repaired or sealed, and pressure test results showing leakage reduction. This is standard on every CleanRun visit - not an add-on, not available only on request. If a company cannot show you the inside of your ducts, they did not document their work. Call (469) 405-6133 and we will explain what you should receive from any duct repair provider.
Ready for a written price and a documented repair? Call CleanRun Air Duct Cleaning Dallas at (469) 405-6133 for your free estimate. We will show you what we find, explain what it costs, and put both in writing before any work begins.
