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 Dryer Vent Cleaning in Denver: What to Know First
CleanRun Air Duct Cleaning Denver provides independent Nikro dryer vent cleaning to homeowners across Denver, from Capitol Hill to Cherry Creek to the Highlands. Most Nikro vent jobs run $180-$340 for a standard single-run residential system, and we deliver a written price before any work starts. As an independent Nikro service provider, we are not affiliated with or authorized by Nikro, but our crews have worked on enough Nikro SL400, SL800, and PD100 series units in Denver’s dry climate to know where lint packs tight and where the aluminum flex fails first. If you own a Nikro dryer vent product and need inspection, cleaning, rerouting, or bird guard installation, call (720) 799-2292. We’ll put a written estimate in your hand before a single panel comes off.
How Nikro Products Fail - and How We Fix Them
- SL800 Series: Collapsed internal baffle from thermal cycling. The SL800’s stamped-steel baffle plate warps after repeated heat cycles, especially in Denver’s altitude where dryers run hotter and longer to achieve the same moisture extraction. The camera shows a 2-3 inch lint dam behind the warped baffle that standard brushing misses. We remove the baffle, document the deformation, and replace with either OEM Nikro SP-BF800 or a quality aftermarket equivalent rated for 450°F continuous duty.
- PD100 Portable Units: Crimped exhaust hose at the first elbow. The PD100’s lightweight 4-inch flex hose, common in Denver townhomes and condo conversions, collapses at any bend sharper than 45 degrees. We find this in Capitol Hill basement laundry closets where the run to the exterior wall is short but tortured. Our fix: reroute with rigid aluminum where code allows, or spec Nikro’s own RH-400 reinforced flex if space demands it. The photo record shows the before collapse and after airflow test.
- SL400 Wall Vents: Broken damper flapper from bird impact or freeze-thaw. Denver’s spring hail and hard freezes crack the SL400’s polypropylene damper flapper, letting cold air backdraft and birds nest. We replace with the SL400-DK damper kit or upgrade to a Guardsman bird-guarded cap if the homeowner wants the problem solved permanently. The old flapper goes in the job bag, photographed.
- Nikro-to-generic transitions: Mismatched collar diameters creating lint ledges. Many Denver homes built 2015-2020 have Nikro vent hoods mated to generic 4-inch duct with a friction-fit collar. The 1/8-inch step collects lint in a ring that grows inward. We cut back to solid pipe, install a proper tapered transition, and run the Nikro SP-LC400 lint catcher if the homeowner wants incremental monitoring.
- SL800 Extended Runs in Highlands Ranch: Sagging horizontal spans. Nikro’s SL800 is rated for 25 equivalent feet, but Denver’s low humidity means homeowners over-dry, pushing more lint further. In Highlands Ranch and similar suburbs, we see 35-foot runs with a belly sag at the mid-span support. We add a rigid support bracket, break the sag, and document the corrected slope in the photo record.
Our Nikro Dryer Vent Cleaning Process

- 1
Call and scope. We ask the model series if you know it, the vent run length, and any symptoms. A live person answers, 24/7. We schedule a window and note: Haven Standard Clause 1 applies - written price before work starts.
- 2
Arrival and inspection. The technician, identified by name before arrival, photographs the exterior hood, the transition behind the dryer, and the first accessible joint. We run a airflow meter (cfm at the hood) to establish baseline. Tomas Reyes still follows the same protocol he learned doing ductwork in Queens apartment buildings: name the part, state what you found, then talk price.
- 3
Written price delivery. The scope and price go in writing. If parts are needed - OEM Nikro or quality aftermarket - both options are priced. No work begins until you sign.
- 4
Cleaning and repair. We use Nikro-compatible brushes and rods, or Rotobrush negative-pressure extraction for heavy buildup. Reroutes, damper replacements, or bird guard installs follow manufacturer torque specs and Denver code.
- 5
Test and document. Post-work cfm reading, thermal camera check at joints for leaks, and photographed before/after of every accessible section. The photo record is delivered as a standard deliverable, not an upsell.
- 6
365-Day Done Right Promise. The written guarantee goes with the invoice. If airflow drops or a joint leaks within a year, we make it right.

FAQs
No. Manufacturer warranties cover defects in materials and workmanship; they do not require brand-authorized service for routine maintenance. We document our process and parts used, so if a warranty claim ever arises, you have a dated service record showing proper care. For questions about your specific Nikro warranty terms, call us at (720) 799-2292 and we’ll review them with you.
Clean on a schedule. In Denver’s low-humidity environment, dryers work harder and lint compacts denser. We recommend inspection every 12-18 months for the SL400 and SL800 series, and every 6-12 months for the PD100 portable units used in multi-family buildings. A clogged vent is a fire hazard; waiting for symptoms (long dry times, hot exterior wall) means the problem is already advanced. Call (720) 799-2292 to schedule - estimates are free.
You receive a Documented Photo Record of every accessible duct section, before and after, as a standard deliverable on every visit. We also record pre- and post-work airflow in cfm at the exterior hood. If the numbers don’t improve, the job isn’t done. This practice has been standard since our first job in 2013.
We stock common Nikro wear items - damper kits, lint catchers, transition collars - and source OEM or quality aftermarket equivalents within 24-48 hours for less common hardware. We do not markup parts; what we pay is what you pay, plus labor at the agreed rate. The written price lists every part number before work starts.
Yes, and it’s common in Denver homes built 2015-2020. Attic temperatures in January drop below 10°F, and moist exhaust flash-freezes at any lint accumulation point, creating an ice dam that blocks airflow and backdrafts moisture into the dryer. We insulate the run, verify slope for drainage, and photograph the attic section specifically. This is a Denver-climate reality that generic vent cleaners often miss. Call (720) 799-2292 for an attic inspection - we’ll put the price in writing before we climb up.
