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 New Braunfels: What to Know First
We provide independent Nikro duct repair and sealing in New Braunfels, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. Typical repair and sealing work runs $340-$780 for residential systems, depending on whether we’re patching a single flex duct run or resealing an entire metal trunk line with mastic. This page is for Nikro equipment owners in New Braunfels who’ve noticed uneven airflow, rising energy bills, or visible duct damage and want a technician who names the actual problem before naming the price. Call (830) 549-6847 for a free estimate.
How Nikro Products Fail - and How We Fix Them
- Nikro Flex-Lok series flex duct: The inner liner on Flex-Lok runs installed in New Braunfels attics between 2015 and 2020 tends to separate from the wire helix where the duct passes over trusses with less than 18 inches of support spacing. The gap pulls conditioned air into the attic and draws attic heat back into the system. We sleeve the damaged section with new flex or, for shorter runs, replace the entire span and strap it at 12-inch intervals to prevent repeat failure.
- Nikro Snap-Lock metal duct seams: The longitudinal seams on Snap-Lock trunk lines loosen where thermal cycling is most severe - in unconditioned New Braunfels attics that hit 140°F in July and drop below 40°F in January. The seam gap is usually invisible from outside but shows up as a 15-25% airflow loss at the far registers. We break the seam, reseat it with a S-cleat or drive cleat, then seal with water-based mastic rated for the temperature swing, not foil tape that’ll cook off in August.
- Nikro collar and takeoff connections: The stamped collar connections on Nikro residential systems crack at the start collar where the flex duct attaches, especially in homes near the Gruene Historic District with original 1980s metal that was retrofitted with Nikro components. The crack propagates slowly; by the time a homeowner feels temperature imbalance at the register, the leak has been dumping air into the ceiling cavity for months. We replace the collar with a heavier-gauge aftermarket equivalent or, if the trunk is thin, fabricate a reinforced tap from 26-gauge sheet metal.
- Nikro plenum degradation: The fiberboard plenums Nikro supplied on package systems through 2018 swell at the corners where condensate collects, particularly in New Braunfels homes with oversized AC units that short-cycle and don’t run long enough to dehumidify properly. The swollen fiberboard delaminates and creates a bypass path around the filter. We cut out the damaged plenum section and build a replacement from double-wall duct board with an exterior vapor barrier, or switch to a galvanized sheet metal plenum if the HVAC cabinet allows the clearance.
- Nikro damper seal failure: The blade seals on Nikro manual balancing dampers harden after 6-8 years in the dry attic air typical of Comal County summers. The damper still moves, but it no longer seats tight, so a zone that’s supposed to be throttled to 30% is passing 60% or more. We replace the damper with a new Nikro OEM unit or, if the original is obsolete, machine a compatible blade seal from silicone-impregnated fabric rated for the static pressure of the system.
Our Nikro Duct Repair & Sealing Process
- 1
Inspection with photo documentation. We run a borescope through every accessible duct run and photograph the failure point - a separated flex liner, a cracked collar, a swollen plenum corner. Tomas Reyes started this practice after learning the trade at BOCES Westchester: show the photo first, explain what you’re looking at, then talk about what happens next.
- 2
Written scope and price. We deliver a written scope that names the exact repair, the parts source (OEM Nikro or quality aftermarket), and the flat price. Haven Standard Clause 1: no work starts without a written price agreed to in advance.
- 3
Parts decision and procurement. For current Nikro lines, we source OEM components through our supply house. For discontinued series, we use aftermarket parts that match or exceed the original specification - never a universal-fit shortcut that’ll fail in two seasons.
- 4
Repair and sealing. We execute the repair, then seal all joints with mastic or appropriate gasket material. On metal systems, we pressure-test to verify static pressure recovery at the air handler.
- 5
Photo record and documentation. We photograph the completed repair and add both before and after images to your job record, delivered as a standard document. The 365-Day Done Right Promise is included in writing.
- 6
System verification. We run the system and verify temperature balance at the affected registers, then note the readings in your service record.
BeforeAfterWhat Nikro Duct Repair & Sealing Costs in New Braunfels

These are whole-system prices, not per-vent teaser rates that balloon once the truck is on your driveway. Every estimate is free, every price is written before work starts, and we offer a Free Second Opinion on any competitor’s written estimate. Call (830) 549-6847 to schedule.
Why New Braunfels Homeowners Call CleanRun Air Duct Cleaning New Braunfels for Nikro Work
We’ve worked on Nikro equipment in New Braunfels since 2013, including the flex-duct-heavy builds in the Copper Ridge and Veramendi developments where the original installer used Nikro components almost exclusively. Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, which matters when your Nikro ductwork is connected to a mixed-brand HVAC cabinet and the failure involves the interface between the two. Every job ends with a Documented Photo Record and the 365-Day Done Right Promise in writing. If the repair fails, we make it right. No manager approval needed. The guarantee is the document.
FAQs
No. Nikro’s warranty covers manufacturing defects in the original equipment, not subsequent service performed by an independent provider. As an independent Nikro service provider, we use OEM or equivalent parts and document the work so any future warranty claim on the original component remains valid. If you’re unsure whether a specific part is still under warranty, we can inspect and advise before you decide on repair or replacement. Call (830) 549-6847 for a free assessment.
Repair is viable when the damage is localized - a single separated flex run, a cracked collar, or a few feet of failed seam - and the remaining ductwork tests within acceptable static pressure range. Replacement makes sense when we find systemic degradation: multiple failure points, plenum delamination, or metal duct with corrosion pitting that will continue to spread. We show you the inspection photos and the pressure test results, then quote both options in writing so you can compare. Call (830) 549-6847 for an exact diagnosis.
Yes, for most lines. Current Nikro series parts are available through our supply house with standard lead times. For discontinued series, we maintain relationships with aftermarket manufacturers and can often fabricate equivalent components from sheet metal or source cross-referenced seals and collars. We never proceed with a repair until we’ve confirmed parts availability and included the source in your written scope.
Most single-point repairs - one flex run, one collar, one damper - take 2 to 4 hours. Full-system sealing for an average New Braunfels home runs 4 to 6 hours. We schedule specific arrival windows, not all-day waits, and we don’t book more jobs than we can document properly. If your repair requires parts we don’t stock, we’ll tell you the lead time before you agree to the scope.
We verify every repair with before-and-after measurements. On metal systems, we test static pressure at the air handler and temperature at the affected registers. On flex repairs, we verify airflow volume with a calibrated anemometer. These numbers, with the photo record, are included in your job documentation. If the readings don’t improve, we don’t consider the job complete. The 365-Day Done Right Promise covers any failure of the repair itself. Call (830) 549-6847 if you have concerns after we’re gone.
