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.

AfterGuardsman Dryer Vent Cleaning in Houston: What to Know First
CleanRun Air Duct Cleaning Houston provides independent Guardsman dryer vent cleaning across Houston, from the Energy Corridor to Pearland and The Woodlands. Most Guardsman jobs run $195-$385 for a standard cleaning, with written pricing delivered before any work begins under Haven Standard Clause 1. We carry OEM and quality aftermarket Guardsman-compatible fittings, and every job ends with a documented photo record of the vent interior, delivered to you before we pack up.
This page is for Houston homeowners who own Guardsman dryer vent products, whether you are looking for routine maintenance, suspect a blockage, or need a full vent reroute after a remodel. Call (346) 251-8919 for a free estimate with a written price.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GV-Series rigid elbows clog at the sweep joint. The 90-degree elbows in the GV line use a slightly tighter radius than competing brands, which concentrates lint at the inner bend. In Houston, where outdoor humidity regularly hits 85% and indoor dryer exhaust cools quickly, that lint pack hardens into a dense mat. We cut in a sweep elbow with a gentler radius, or install a clean-out port if the run geometry demands keeping the original fitting.
- Guardsman flexible transition ducts (GVT-4 and GVT-8) sag and hold water. These semi-rigid flex lines are common in Houston townhomes built 2015-2020, and they sag between floor joists in longer vertical runs. The sag creates a low spot where lint and condensation collect, which is why we find mold staining on the ceiling below in some Energy Corridor jobs. We replace with rigid aluminum where code allows, or support the flex line on proper hangers with a slight upward pitch toward the exterior.
- Guardsman wall caps with backdraft dampers (GVC-100 series) seize open or closed. The nylon hinge pin swells in Gulf Coast humidity, and the damper either hangs open, letting in wasps and attic air, or jams shut, tripping the dryer’s thermal cutoff. We stock the OEM damper assembly and a stainless aftermarket alternative; the stainless unit costs more but we have not seen one seize in twelve years of Houston installs.
- Guardsman bird guard screens (GBG-4) clog with dryer sheet residue. The fine mesh that keeps birds out also traps the waxy film from fabric softener sheets, which is nearly invisible until airflow drops by 40%. We remove the screen for cleaning with a degreasing agent, or replace it with a Guardsman-compatible vent hood that uses louvered closure instead of mesh.
- Guardsman extended vent kits (GVE-12, GVE-20) exceed effective length in Houston’s flat terrain. These kits are rated for 12 and 20 feet of duct, but that rating assumes minimal elbows and dry climate. In Houston, where slab-on-grade homes often force two elbows minimum and summer humidity reduces effective airflow, we measure actual static pressure at the dryer’s exhaust port. If the reading exceeds 0.75 inches water column, we reroute or add an inline booster fan, and we document the before-and-after pressure reading in your job record.
Our Guardsman Dryer Vent Cleaning Process
- 1
Static pressure test and visual inspection. We connect a manometer at the dryer exhaust port to measure backpressure before touching anything. A reading above 0.5 inches w.c. on a Guardsman system tells us where to look first.
- 2
Photo documentation of the full run. Our camera goes through every accessible section of duct. The photo goes first. The pitch comes later, if it’s warranted.
- 3
Parts decision: OEM Guardsman or quality aftermarket. For warranty-active systems, we use Guardsman OEM fittings. For out-of-warranty jobs, we offer stainless aftermarket alternatives that hold up better in Houston humidity, with the trade-offs explained in writing.
- 4
Negative-pressure extraction and mechanical agitation. We use Rotobrush and Nikro equipment to dislodge packed lint, with HEPA-contained collection so nothing enters your living space.
- 5
Post-cleaning pressure test and airflow verification. We retest at the same port to confirm backpressure dropped. The second reading goes in your written job record alongside the before photos.
- 6
Written invoice, 365-Day Done Right Promise, and photo record delivery. You get the scope, the pricing, the warranty terms, and the image files before we leave.

What moves the price: length of run, number of elbows, accessibility (crawl space, attic, or enclosed soffit), and whether we are cleaning or replacing components. We do not quote per-vent or per-foot. One flat price per system, agreed in writing, before any work begins. Call (346) 251-8919 for your exact number.
Why Houston Homeowners Call CleanRun Air Duct Cleaning Houston for Guardsman Work
We are independently owned and operated under the Haven Standard, not a franchise, and we have documented 52,000+ jobs since 2013. Every Guardsman job gets the same deliverables: written price first, background-checked uniformed crew identified by name before arrival, and a photo record of every duct run before and after. The 365-Day Done Right Promise is backed in writing, not subject to manager approval.
Tomas Reyes, our owner, put in years of hands-on duct work across the northeast before relocating to Houston, where Gulf Coast humidity and the mix of 1970s retrofits and new construction gave him a working education in how quickly a mildly dusty duct becomes a debris problem. We also service Lennox, Trane, and Carrier vent systems, so if your home has mixed brands or a prior owner swapped components, we do not guess at compatibility.
FAQs
No, routine cleaning by an independent service provider does not void a Guardsman warranty, provided no components are altered or damaged during service. We use Guardsman-compatible tools and document the condition of every fitting before and after, so if a warranty question arises later, you have a dated photo record of what was touched and what was not. Call (346) 251-8919 if you need a copy of our service documentation for a warranty claim.
Replacement is indicated when the duct material itself is compromised, not just dirty. We look for corrosion holes in galvanized sections, cracks in rigid aluminum elbows, or delamination of flexible duct. On a recent job in Sugar Land, the camera showed a 3-inch rust perforation in a GV-Series elbow that lint cleaning would not have addressed. The photo record makes this distinction visible before you commit to either path.
We stock both. For warranty-active systems, we source Guardsman OEM dampers, elbows, and wall caps. For out-of-warranty jobs, we offer stainless aftermarket alternatives that resist Houston humidity better, with the price and material difference stated in writing before you choose. We do not default to either; we explain the trade-off and let the documentation guide the decision.
Every 12-18 months for a typical household of 2-4 people, and every 8-12 months if you wash pet bedding, use fabric softener sheets heavily, or run the dryer more than five loads weekly. Houston’s humidity accelerates lint compaction, so the upper Gulf Coast schedule runs shorter than drier climates. We note the recommended return date on your written job record and do not chase you with marketing calls before then.
Confirm the dryer itself is heating, check that the lint screen is clean, and verify the exterior flap moves when the dryer runs. If the flap does not budge, you likely have a blockage or a seized Guardsman damper, which is not a DIY fix. The flexible transition duct behind the dryer is also a common failure point on Guardsman GVT lines, but we do not recommend pulling the unit out yourself on tile or wood flooring. Call (346) 251-8919 and we will inspect it as part of the free estimate.
