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 Lewisville: What to Know First
We provide independent Guardsman dryer vent cleaning in Lewisville with written prices delivered before work starts and a documented photo record of every vent run. Most Guardsman dryer vent jobs in Lewisville are completed in a single scheduled visit, with whole-system pricing typically running $180-$340 depending on vent length, accessibility, and whether rerouting is needed. This page is for Lewisville homeowners who own Guardsman venting products and want a technician who names the part, shows the photo, and puts the price in writing before touching a tool. Call (940) 240-8552 for a free estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GSV-8 Series: Collapsed flex behind the dryer. The GSV-8’s semi-rigid transition duct crushes flat when pushed back against the wall, creating a lint trap that the owner’s manual warns about but doesn’t show how to spot. In Lewisville homes built 2015-2020, we find this behind roughly one in three GSV-8 installations. We replace the crushed section with a Guardsman-compatible UL-listed semi-rigid duct and photograph the new slope before reconnecting.
- Guardsman GSV-12 Extended Run: Sagging horizontal runs in attic spaces. The GSV-12’s 25-foot rated length tempts installers to stretch it across Lewisville attics with minimal support. Summer attic heat in Denton County softens the polymer, and the run sags at mid-span. Lint pools there, then backs up to the dryer. We install additional support straps per IRC M1502.4.4 and run a rotary brush through the full length, with before-and-after photos from the camera.
- Guardsman Bird Guard BG-4: Clogged mesh in Lewisville’s cottonwood season. The BG-4’s fine mesh stops birds but also traps seed fluff from the cottonwoods lining Lewisville’s Creek Valley neighborhoods each May. The dryer labors, heats up, and the homeowner assumes the dryer is failing. We remove the guard, clean the mesh with compressed air, and show the homeowner the seasonal maintenance interval. Replacement BG-4 units are available if the frame is cracked.
- Guardsman GSV-6 Basic Vent: Corroded termination cap at the Gulf Coast humidity line. The GSV-6’s painted steel cap rusts through faster in Lewisville than in drier parts of North Texas. We’ve pulled caps off Castle Hills homes where the damper was rust-welded open, letting in wasps and attic air. We source a stainless aftermarket equivalent that fits the GSV-6 collar, or transition to a Guardsman GSV-6SS if the owner wants OEM.
- Guardsman GSV-10 Periscope: Disconnected joints in tight closets. The GSV-10’s adjustable periscope is popular in Lewisville’s newer townhomes where the laundry closet is barely 30 inches deep. The telescoping joints work loose from vibration, especially on second-floor installations. We find lint packed into the wall cavity behind the joint. We reseat with foil-backed tape rated to 180°F, not standard duct tape, and add a mechanical support bracket.
Our Guardsman Dryer Vent Cleaning Process

- 1
Written price delivered. We scope the job over the phone or in person, then provide a written price under Haven Standard Clause 1 before any panel comes off. No exceptions.
- 2
Camera inspection of the full run. We feed a borescope from the dryer connection to the termination, documenting lint buildup, joint condition, and any Guardsman-specific wear. Here’s the before photo. Now let’s talk about what happens next.
- 3
Parts decision with the owner. OEM Guardsman parts when available and appropriate; quality aftermarket when the OEM part is backordered or the owner prefers a specification upgrade. We name the manufacturer, not “comparable quality.”
- 4
Negative-pressure extraction and rotary brushing. We use Rotobrush and Nikro equipment to dislodge lint and extract it under contained suction. The vent is brushed, not just blown through.
- 5
Flow verification and photo record. We measure exhaust velocity with an anemometer and deliver the after photos, written scope, and 365-Day Done Right Promise as a single job record.

AfterWhat Guardsman Dryer Vent Cleaning Costs in Lewisville
Whole-system Guardsman dryer vent cleaning in Lewisville runs $180-$260 for standard single-story runs under 15 feet with direct exterior termination. Extended runs, attic or crawlspace access, or Guardsman vent rerouting moves the range to $280-$340. Bird guard installation or cap replacement is quoted separately, typically $45-$85 parts and labor. What moves the price: vent length, number of elbows, whether we need to pull the dryer for access, and if the existing Guardsman components are salvageable or require replacement. We do not quote per-vent or per-foot pricing. Every estimate is free, written, and valid for 30 days.
Why Lewisville Homeowners Call CleanRun Air Duct Cleaning Lewisville for Guardsman Work

We’ve been running jobs in Lewisville since 2013, including the older flex-duct homes near Castle Hills where vent runs sag and accumulate debris that doesn’t show until the camera goes in. Tomas Reyes and our crew know Guardsman product lines from hands-on work, not a dealer training slideshow. We also service Lennox, Trane, and Carrier venting systems, so we’re not guessing when a mixed-brand installation needs integrated repair. Every job carries the 365-Day Done Right Promise in writing, Haven Standard Clause 3 verified crew identification, and the documented photo record we’ve delivered on every visit since our first job.
FAQs
No. As an independent Guardsman service provider, we use warranty-safe practices and OEM or equivalent parts. Guardsman’s warranty covers manufacturing defects, not maintenance; professional cleaning does not affect it. Call (940) 240-8552 if you’d like the specific warranty language reviewed before scheduling.
We stock common Guardsman replacement caps, bird guards, and transition ducts, and we source less common items through our supplier network. You don’t need to order anything. We name the part and its origin in the written scope before work starts.
Replacement is necessary when the camera shows corrosion holes, crushed flex that can’t be reshaped, or joint separation inside a wall cavity. Cleaning is sufficient when the duct is structurally sound but obstructed. We show you the photo and explain which category applies before quoting either service.
The $79 coupon model typically sends a technician with a shop vac and 20 minutes. We photograph the inside of every run, use Rotobrush and Nikro negative-pressure equipment, and deliver a written record. The price difference is the difference between vacuum noise and documented work.
Every 12-18 months for a typical household, sooner if you dry pet bedding frequently or run multiple loads daily. Lewisville’s hard water and heat mean lint compacts denser than in cooler climates. We note the recommended next service date on your job record.
