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.

AfterNikro Duct Repair & Sealing in The Woodlands: What to Know First
We provide independent Nikro duct repair and sealing in The Woodlands, with most jobs completed in a single scheduled visit and a written price delivered before any work begins. Typical repairs run from $340 for a single flex-duct run with sealing to $1,200 for multi-zone metal duct restoration with full mastic treatment. As an independent Nikro service provider, we are not affiliated with or authorized by Nikro, which means we source parts based on fit and durability rather than brand-mandated channels. This page is for homeowners in The Woodlands who have found a Nikro-labeled component in their duct system, suspect a leak or break, and want to know what honest repair looks like before calling anyone. Questions? Call (346) 248-1474.
How Nikro Products Fail - and How We Fix Them
- Nikro SL2000 Series Flex Duct: Collapsed Inner Liner at Elbows - The SL2000’s wire-reinforced inner liner fatigues where flex duct bends sharply at trunk take-offs, especially in The Woodlands homes with attic installations where summer attic temperatures exceed 140°F. The wire helix kinks, the liner tears, and conditioned air dumps into the attic. We cut back to sound duct, install a rigid elbow where space allows, and re-terminate with mastic-sealed collars rather than tape alone.
- Nikro Metal Duct Transitions: Galvanized Seams Opening at Corners - Long runs of Nikro rectangular metal duct in older The Woodlands builds, particularly in Grogan’s Mill and Panther Creek, develop seam separation where the Pittsburgh lock was factory-pressed too tight. The gap is often hairline until negative-pressure testing reveals it. We break the corner, re-crimp with a brake, and seal with fiber-reinforced mastic rated for negative-pressure systems.
- Nikro Insulated Flex: Waterlogged Outer Jacket - The Woodlands’ Gulf Coast humidity penetrates compromised vapor barriers on Nikro insulated flex, saturating the fiberglass layer. The duct loses R-value and grows heavy enough to pull down supports. We replace the run with new flex rated for our climate zone, seal all jacket terminations with closed-cell foam, and photograph the old water line for the record.
- Nikro Register Boots: Detached from Drywall or Subfloor - Plastic Nikro register boots shrink-crack where they meet finished surfaces, creating a bypass that pulls attic air directly into the room. Homeowners feel it as uneven temperatures or dust streaking near the vent. We remove the boot, install a metal adapter with a foam gasket, and seal the penetration with fire-rated caulk before re-installing the grille.
- Nikro Duct Board Plenums: Erosion at Air Handler Connection - Fiberglass duct board plenums, common in Nikro systems from the 2000s, erode where high-velocity air enters from the blower. The face delaminates, shedding fibers into the airstream. We fabricate a galvanized transition piece, line it with closed-cell insulation, and seal with mastic to protect the remaining duct board from further erosion.
Our Nikro Duct Repair & Sealing Process
- 1
Inspection with documented photo record. We run a borescope through every accessible duct run, photographing the Nikro label, any damage, and surrounding conditions. The before photo does the talking. Everything else is just paperwork.
- 2
Written scope and price. Haven Standard Clause 1: we deliver a written price before any panel comes off, itemized by duct run and repair type. No verbal estimates, no “call for a quote.”
- 3
Parts decision: OEM Nikro or quality aftermarket. We check availability on genuine Nikro components, but many repairs use cross-referenced aftermarket parts from Abatement Technologies or Guardsman that meet the same pressure and temperature specs. We note the source on the work order.
- 4
Repair and seal. We execute the repair, then seal all joints with mastic or foil tape rated for the application. Metal-to-metal gets fiber-reinforced mastic; flex-to-metal gets a clamp-plus-mastic combination.
- 5
Negative-pressure test and final photo record. We pressurize the system and check with a smoke pencil at every repair. Then we photograph the finished work and add both sets of images to your job record.
- 6
365-Day Done Right Promise in writing. If the repair fails, we make it right. The guarantee is printed, dated, and signed before we leave.

Why The Woodlands Homeowners Call CleanRun Air Duct Cleaning The Woodlands for Nikro Work
We’ve worked on Nikro components in The Woodlands since 2013, including jobs in Panther Creek where the original flex-duct installations from the late 1980s still surprise us with compacted insulation and disconnected joints most homeowners never knew were there. Tomas Reyes, our owner, photographs every register and trunk line before touching anything, then walks customers through what the images actually show rather than describing it in the abstract. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so if your repair reveals a broader compatibility issue, we don’t hand you off to another contractor. The 365-Day Done Right Promise, the documented photo record, and the written price are standard on every job, not upgrades.
FAQs
Nikro’s warranty on duct products covers manufacturing defects, not field repairs, so independent service does not void what remains of the original coverage. We document the serial number and installation date before starting work so you retain any valid claim. If you have concerns about a specific component, call (346) 248-1474 and we’ll check the labeling together.
Replacement makes sense when the duct material itself has degraded, such as waterlogged flex with collapsed insulation or duct board with face erosion exceeding 25% of the surface. Repair is viable for isolated seam failures, detached boots, or single-run damage in otherwise sound systems. Our inspection determines which path applies, and we quote both options in writing when both are possible.
Current-production Nikro parts are available for systems manufactured after roughly 2010. For older lines, we cross-reference to aftermarket components from Abatement Technologies or Guardsman that match the pressure and temperature specifications. We never install a part we cannot verify will perform.
Most single-run repairs are completed in two to four hours. Multi-zone restorations may extend to a full day. We schedule by the job, not the hour, so the crew stays until the negative-pressure test passes and the photo record is complete.
We test every repair with a negative-pressure smoke test at operating pressure and include the results in your documented photo record. If smoke shows at any joint, we re-seal and retest before signing off. The images and test notes are yours to keep.
