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.
Guardsman Dryer Vent Cleaning in Littleton: What to Know First
We provide independent Guardsman dryer vent cleaning in Littleton, from routine lint removal to full vent rerouting, with a written price delivered before any work starts and a documented photo record of every run. Most Guardsman jobs we handle in Littleton are completed in a single visit, and our flat-rate pricing for a standard system runs $189 to $349 depending on vent length, access difficulty, and whether the Guardsman termination cap or bird guard needs replacement. This page is for Guardsman owners in Littleton who want to know what specifically fails on their equipment, what the repair should cost, and how to verify the work was actually done. Call (720) 315-7291 for a free estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GSV Series termination caps seize in the closed position. The GSV line uses a louvered cap with a lightweight aluminum hinge that corrodes faster than comparable steel designs, especially in Littleton’s freeze-thaw cycles where meltwater refreezes in the hinge pocket. We replace with a stainless-steel equivalent or the Guardsman OEM cap if the homeowner prefers, and we photograph the hinge corrosion before removal so the owner sees why the louvers stuck.
- Guardsman GDF flex duct collapses at the first elbow behind the dryer. The GDF series ships with a thinner-walled flex duct than competing brands, and the repeated heat cycling in a typical Littleton laundry room causes sagging where the duct turns upward into the wall. We reroute with rigid metal duct where code allows, or spec a higher-grade flex with a 4-ply rating if space demands it. The camera doesn’t negotiate - it just shows what’s there.
- Guardsman GWC wall-box assemblies collect lint at the damper interface. The GWC’s internal damper sits close to the wall plane, creating a ledge where lint packs hard enough to prevent full closure. In homes near Chatfield Reservoir, we’ve found this compounded by higher outdoor humidity drawing more lint into the box. We disassemble the wall box, clean the damper seat with a narrow brush and vacuum, and test for positive seal before reassembly.
- Guardsman bird guards on the GSV-R series clog with seed debris from mature Littleton landscaping. The GSV-R’s mesh is finer than code-minimum to meet its own bird-exclusion rating, which works until cottonwood fluff or pine needle fragments pack the screen. We clean the mesh in place when possible, or replace with a Guardsman-compatible guard with a slightly coarser mesh that still excludes birds but passes debris better.
- Guardsman GLE extended-run systems lose airflow at the inline booster fan. The GLE series relies on a small inline fan for runs over 25 feet, and the fan blade fouls with lint that bypasses the primary lint trap. We locate the fan housing, document blade condition with the inspection camera, and clean or replace the fan as needed. Most Littleton homes with GLE systems are in newer subdivisions like Roxborough where the laundry room sits far from an exterior wall.
Our Guardsman Dryer Vent Cleaning Process

- 1
Inspection with photo documentation. We feed a camera through the full vent run and show the homeowner the footage before quoting. This establishes the debris load, flex duct condition, and any Guardsman-specific component wear.
- 2
Written price delivered. We provide a flat rate for the scope, with line items for Guardsman OEM parts versus quality aftermarket alternatives. No work begins until the homeowner signs the written scope.
- 3
Lint removal with negative-pressure extraction. We use a Nikro HEPA vacuum with a rotating brush head sized to the duct diameter, pulling debris backward toward the vacuum rather than blowing it into the home.
- 4
Component repair or replacement. Guardsman caps, dampers, bird guards, or inline fans are addressed per the agreed scope, with OEM or aftermarket parts as selected.
- 5
Airflow verification and final photo record. We measure exhaust velocity at the termination and photograph the cleaned duct interior. Both numbers and images go into the job record delivered to the homeowner.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect immediately, backed by Haven Standard Clause 5: Documented Accountability.

Why Littleton Homeowners Call CleanRun Duct Repair & Cleaning for Guardsman Work

We’ve been cleaning ductwork in Littleton since 2013, including plenty of jobs in the Columbine Knolls neighborhoods where the homes are older and the duct liners tend to tell a longer story than the listing price suggests. Tomas Reyes, our owner, pulls the inspection camera before quoting anything, then walks homeowners through exactly what the footage shows - debris load, flex duct condition, register seal gaps - in plain terms, not sales language.
Every Guardsman job carries the 365-Day Done Right Promise in writing, not as a verbal courtesy. Our crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The documented photo record from every visit lets you verify the difference between real work and vacuum noise. And if you’ve already got a written estimate from another company, we’ll provide a free second opinion with our own number next to it.
FAQs
No. As an independent Guardsman service provider, we use warranty-safe practices and OEM or equivalent parts. The Magnuson-Moss Warranty Act prohibits manufacturers from voiding warranties solely because an independent technician performed maintenance. We document parts sources and installation methods so any warranty claim you file later has a clear record. Call (720) 315-7291 if you want us to review your specific Guardsman warranty terms before scheduling.
Replacement becomes necessary when the inspection camera shows duct wall damage, repeated flex duct collapse, or a termination cap that no longer seals despite cleaning. For most Guardsman systems in Littleton, cleaning every 12 to 18 months prevents the buildup that accelerates wear. We show you the camera footage and explain which category your system falls into before any price is discussed.
We stock both. Guardsman OEM caps, dampers, and bird guards are available with a 2-3 day order lead time for less common GLE components. Our aftermarket equivalents meet the same UL listings and often outperform the original on durability, particularly the stainless-steel hinge caps we use for GSV replacements. We quote both options with part numbers you can verify.
Every 12 to 18 months for typical residential use, or every 6 to 9 months if you run multiple loads daily or dry pet bedding regularly. Littleton’s dry winters reduce mold risk but increase static cling that pulls more lint past the trap. We include a recommended interval in your written job record based on what the camera showed.
The documented photo record shows every duct run before and after, with timestamps. You receive these as part of the standard job deliverable, along with the written scope, the signed price agreement, and the 365-Day Done Right Promise. If a future buyer or inspector asks about vent maintenance, you have a dated, photographed record from a licensed, insured company. Call (720) 315-7291 to schedule.
