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.
Nikro Duct Repair & Sealing in Leander: What to Know First
We provide independent Nikro duct repair and sealing in Leander, typically completing scheduled jobs within one business day of your call. Most residential repairs run $280-$620 for a single system, with a written price delivered before we remove the first panel. We are not affiliated with or authorized by Nikro; we are an independent Nikro service provider that services the equipment Leander homeowners already own.
This page is for Nikro owners in Leander, Cedar Park, and the Crystal Falls area who have noticed uneven airflow, rising utility bills, or visible damage to flex duct or metal trunk lines. If your Nikro system is part of a newer build in Leander’s 78641 corridor, the combination of construction debris and Hill Country temperature swings has likely stressed connections that were never properly sealed at install. Call (737) 252-1285 for a free estimate with a written price before any work starts.
How Nikro Products Fail - and How We Fix Them
- Nikro SL4000 Series flex duct: collar separation at plenum connections. The SL4000’s wire-reinforced collar can work loose from the plenum box in Leander homes where seasonal expansion from 100°F August afternoons to near-freezing January nights cycles the metal. We cut back to sound material, install a Nikro-compatible draw-band collar, and seal with mastic - not foil tape, which fails in the same cycle.
- Nikro PD5000 portable ducting: abrasion wear at sharp bends. The PD5000’s lighter-gauge jacketing, common in Leander garage and attic installations, chafes against truss brackets. Our camera shows the fiberglass exposure before we quote. We sleeve the damaged section with Nikro-spec R6 flex or replace the run if the wire helix is compromised.
- Nikro SV6000 static vent connections: gasket hardening and air leak. The SV6000’s EPDM gasket degrades faster in Leander’s UV-exposed attic environments than in conditioned spaces. We replace with fresh gasket stock rated for 180°F continuous, then pressure-test the seal.
- Nikro metal trunk lines: seam separation at longitudinal joints. Factory-seamed trunk runs in Leander’s 2015-2022 builds often relied on pressure-sensitive tape that releases as the house settles on Hill Country clay. We break the old seal, re-crimp where needed, and apply water-based mastic with embedded fabric mesh - the repair outlasts the original.
- Nikro return-air boots: collapse at unsupported spans over 4 feet. The return boot in a two-story Leander home we serviced last March had sagged until the flex kinked, cutting airflow by roughly 40%. We installed a support strap every 30 inches per SMACNA guidelines and replaced the crushed section with new Nikro-compatible flex.
Our Nikro Duct Repair & Sealing Process

- 1
Inspection with photo documentation. We feed a camera through every accessible duct run and photograph what we find. Tomas Reyes started this practice after years in the Northeast seeing homeowners quoted for work with no visual evidence. Show the photo first. Then talk about what comes next.
- 2
Written scope and price. We deliver a single flat price for the system, not per-vent arithmetic. Haven Standard Clause 1: the price is fixed before work begins.
- 3
Parts decision: OEM Nikro or quality aftermarket. We stock Nikro-compatible collars, gasket, and flex. If your repair requires a proprietary Nikro component we don’t carry, we source it with a 48-hour lead time and tell you before you agree to anything.
- 4
Repair and seal. We execute the scope: mastic application, collar replacement, insulation restoration, or trunk re-seaming. Every joint is accessible for future inspection.
- 5
Negative-pressure test. We verify seal integrity with a duct blaster or calibrated manometer, depending on system access. The test shows measurable improvement, not just a visual check.
- 6
Photo record delivery and 365-Day Done Right Promise. You receive before-and-after images of every run we touched, plus the written warranty. If it’s not right, we make it right - backed in writing, not subject to manager discretion.

FAQs
No. Nikro’s limited warranty covers defects in materials and workmanship from the factory; independent repair of field-installed duct connections does not affect it. We document our work with photos and a written scope so any future warranty claim on the original equipment remains clean. Call (737) 252-1285 if you need help understanding what’s factory-covered versus what’s field maintenance.
We determine this during inspection. Nikro’s SL4000 and PD5000 series use proprietary collar diameters in some sizes; SV6000 vent gaskets are standard EPDM and accept quality aftermarket. We tell you which we’re using and why before you sign the scope. Our written estimate specifies OEM or aftermarket for every component.
Replace if the wire helix in multiple flex runs is corroded or if trunk line corrosion exceeds 20% of surface area. Repair if damage is localized to collars, seams, or one or two runs. We show you the camera evidence and quote both paths when both are viable. Call (737) 252-1285 for an inspection that answers this with photos, not opinions.
We typically schedule within one to three business days. We do not promise same-day dispatch because proper inspection and repair take time we won’t rush. Emergency calls for complete airflow loss get priority, but most Leander Nikro jobs are scheduled maintenance that benefits from a thorough camera inspection first.
We deliver the before-and-after photo record of every duct run as a standard job deliverable, plus negative-pressure test results where applicable. Haven Standard Clause 5: Documented Outcomes. If the photos don’t show the work, we don’t charge for it - Tomas Reyes has operated under that rule since 2013.
