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 Johns Creek: What to Know First
We provide independent Nikro duct repair and sealing in Johns Creek, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. A typical Nikro duct sealing project runs $380-$720 depending on system size and accessibility, while flex duct repair or metal duct patching ranges $220-$540 per run. We’re not affiliated with Nikro - we are an independent service provider - so our recommendations are based on what your system actually needs, not a manufacturer’s script. If you own a Nikro air duct cleaning machine, negative air unit, or portable HEPA system and the attached ductwork is leaking, disconnected, or pulling from the wrong places, we can fix it. Call (470) 326-1926 for a free written estimate.
How Nikro Products Fail - and How We Fix Them
- Nikro PS1000 / PS2000 Portable Air Scrubber duct connections: The 10-inch intake collar on these units cracks at the mounting flange after repeated relocation, especially in Johns Creek’s humidity cycle where plastic fatigues faster than in drier climates. We replace with a reinforced metal collar and seal with mastic, not tape, so the negative-pressure seal holds under load.
- Nikro SL2000 / SL4000 Duct Truck flex connections: The 12-foot flex bridge between the truck-mounted vacuum and the home’s main trunk is prone to abrasion where it contacts foundation edges or landscaping. We sleeve the contact point with metal flex or reroute through a protected chase, then pressure-test to verify no intake-side leaks that would compromise extraction.
- Nikro HEPA500 / HEPA1000 filter housing gaskets: The silicone gasket on the filter access door compresses permanently after about 18 months of regular use, creating a bypass that dumps unfiltered air back into the workspace. We stock the OEM gasket and the quality aftermarket equivalent; we show you both, explain the warranty implication, and let you choose.
- Nikro RV340 / RV540 Recovery Vacuum hose barb fittings: The plastic barb on these wet/dry recovery units strips threads if overtightened during filter changes, a common issue we see in rental units passed between operators. We retap for a brass insert or replace the housing outright, depending on how much material remains.
- Nikro AFD2500 Air Filtration Device plenum seams: The spot-welded seams on the galvanized plenum box fatigue at the corners when these units run continuous-duty in commercial settings. We seal with fire-rated mastic and add mechanical reinforcement at the stress points, which extends service life without voiding the electrical safety certification.
Our Nikro Duct Repair & Sealing Process

- 1
System inspection with photo documentation. We photograph every connection, seam, and flex joint before touching anything. The photo goes first. The price comes after.
- 2
Written scope and price. Haven Standard Clause 1: a single flat price for the complete repair, delivered in writing before work begins. No per-foot add-ons, no “we found another issue” mid-job.
- 3
Parts decision with options. For Nikro units still under manufacturer warranty, we source OEM gaskets and collars when available. For out-of-warranty equipment, we show you the quality aftermarket equivalent and explain the trade-off.
- 4
Repair and seal. We use mastic sealant on metal, proper flex connectors on transitions, and mechanical reinforcement where the unit will see stress. Every joint is accessible for future service.
- 5
Pressure verification and photo record. We test negative-pressure integrity where applicable, then photograph the completed work. The full record, before and after, is delivered as a standard job deliverable.
- 6
365-Day Done Right Promise in writing. If the repair fails or leaks within a year, we make it right. The guarantee is a signed document, not a verbal assurance.

AfterWhat Nikro Duct Repair & Sealing Costs in Johns Creek
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Flex duct repair/replacement (per run) | $220-$380 | Length, attic vs. crawlspace access, whether the plenum connection is also compromised |
| Metal duct sealing with mastic (per system) | $380-$620 | System size, number of seams, accessibility behind finished basement ceilings |

Homes near the Chattahoochee River corridor in Johns Creek often run dehumidifiers harder, which means more condensation at duct seams and more frequent mastic fatigue. We factor this into our inspection, not our invoice. Call (470) 326-1926 for a free written estimate - we put our number next to any competitor’s quote under our Free Second Opinion policy.
Why Johns Creek Homeowners Call CleanRun Air Duct Cleaning Johns Creek for Nikro Work

Tomas Reyes and our crew have serviced homes throughout Johns Creek since 2013, including the two-story builds around Medlock Bridge where zoned systems hide accumulation behind secondary return boxes. We know Nikro equipment because we work on it regularly - not as a sideline to other brands, but as part of a roster that includes Rotobrush, Abatement Technologies, Honeywell, Aprilaire, and Guardsman units. When a Nikro part is backordered, we can advise whether a quality aftermarket substitute makes sense or if waiting preserves your warranty. Haven Standard Clause 3: Verified Crews means every technician is background-checked, uniformed, and identified by name before arrival. The 365-Day Done Right Promise applies to every job, and the photo record is included, not an upsell.
FAQs
No, if the repair uses OEM parts and follows manufacturer service guidelines. We are an independent Nikro service provider, not an authorized dealer, so we check your warranty status before recommending OEM versus aftermarket. If your unit is still under warranty, we source genuine Nikro gaskets, collars, and housings when available and document the part numbers for your records. Call (470) 326-1926 and we’ll verify your serial number.
Replace when the repair exceeds 60% of replacement cost or when the unit has failed twice in the same component. We show you the math in writing, including the expected service life of the repair versus a new unit. For Nikro portable units that see commercial duty, we also factor in downtime cost. Call (470) 326-1926 for a free written comparison.
Most residential Nikro duct sealing and minor repairs are completed in two to four hours. Flex duct replacement in a crawlspace may take longer depending on access. We schedule by the job, not by the hour, so the price does not change if unexpected complications arise. Call (470) 326-1926 to schedule.
We stock common wear parts for PS-series, SL-series, and HEPA units going back to 2010. For discontinued models, we maintain relationships with aftermarket manufacturers and can often fabricate or adapt equivalent components. We tell you upfront if a part is unavailable so you can decide before we start. Call (470) 326-1926 with your model and serial number.
You receive a Documented Photo Record of every duct run and connection point, before and after, as a standard deliverable on every job. We also pressure-test sealed systems where applicable and note the readings on your written invoice. This practice has been standard at CleanRun since our first job in 2013. Call (470) 326-1926 to schedule an estimate.
