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 Duct Repair & Sealing in Spring: What to Know First
We provide independent Guardsman duct repair and sealing in Spring, TX, with most jobs completed in a single visit and a written price delivered before any work begins. A typical Guardsman repair runs $280-$620 depending on whether we’re sealing accessible joints or replacing damaged flex duct runs behind drywall. As an independent Guardsman service provider, we’re not affiliated with or authorized by the manufacturer, which means we source parts based on what fits your system and your budget, not a dealer network.
This page is for Spring homeowners who found their Guardsman system on the inspection report, noticed uneven airflow from room to room, or watched their energy bill climb without explanation. If your home sits near Gleannloch Farms or anywhere in the 77373-77389 corridor, you’ve probably got the same clay-heavy soil and older construction we’ve been working in since 2013. Call (346) 423-3631 for a free estimate, or bring us a competitor’s written quote for a free second opinion under Haven Standard Clause 1.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GDS series flex duct: seam separation at the plenum connection. The GDS line uses a lighter-grade mylar outer wrap that fatigues faster than metalized polyester in Houston’s attic heat cycles. In Spring homes built 2015-2019, we regularly find the first three feet of flex pulled away from the supply plenum, dumping conditioned air into the attic. We cut back to sound material, install a proper draw band with mastic sealant, and photograph the repair before closing.
- Guardsman GDM metal duct: corrosion at condensate contact points. The GDM’s galvanized coating holds up well until a secondary drain pan overflows or a coil leaks. We’ve replaced entire trunk lines in Windrose and Augusta Pines where a single drip point rotted through the duct wall in eighteen months. Our fix is a localized patch with matching gauge metal, sealed with water-based mastic, not tape that’ll peel when the humidity spikes.
- Guardsman GDH hybrid systems: insulation collapse inside flex runs. The GDH combines metal trunk with flex branches, and the flex insulation can delaminate from the inner core when attic temperatures exceed 140°F, which happens most afternoons in July and August around here. The symptom is a whistling register and weak airflow. We scope the run with a camera, show the homeowner the collapsed liner, and replace the affected section with R-8 flex rated for Texas attics.
- Guardsman GDR return air plenums: debris intrusion from negative pressure. Spring’s clay soil generates fine particulate that gets sucked into return plenums through any gap in the building envelope. In homes near construction zones, we’ve pulled out enough material to fill a five-gallon bucket from a single GDR plenum. We seal the plenum seams with fiber-reinforced mastic and add a secondary filter rack if the original’s undersized.
- Guardsman GDS-GDH transition fittings: factory crimp failures. The snap-lock fittings between GDS flex and GDH metal trunk can work loose if the original installer didn’t support the flex properly. The gap is often small enough that a homeowner only notices as a warm room or a dusty register. We reseat the fitting, add a support strap within 18 inches of the connection per SMACNA guidelines, and seal with mastic, not foil tape that’ll dry out.
Our Guardsman Duct Repair & Sealing Process
- 1
Camera inspection before quote. Tomas Reyes pulls camera footage before quoting anything. The camera doesn’t negotiate. You’ll see what we see, and the written price follows.
- 2
Parts decision: OEM or quality aftermarket. Guardsman OEM parts carry a 90-day manufacturer warranty but often require longer lead times. We stock compatible aftermarket fittings from Abatement Technologies and Honeywell that meet the same pressure ratings and carry our 365-Day Done Right Promise.
- 3
Repair execution under negative pressure. We isolate the affected duct run, contain debris with a Nikro negative-pressure extraction setup, and complete the repair without contaminating the rest of your system.
- 4
Post-repair pressure test. Every sealed joint gets a smoke-pencil check. Every replaced run gets a static pressure reading compared to your system’s design spec.
- 5
Documented photo record delivery. Before-and-after photos of every duct run, uploaded to your job record before we leave. This has been standard since our first job in 2013.
- 6
Written guarantee activation. The 365-Day Done Right Promise goes into effect the moment we finish, backed in writing, not subject to manager approval.

| Full trunk line replacement (Guardsman GDM) | $1,200-$2,400 | Linear footage, insulation wrap, access difficulty |
These are whole-system prices, not per-vent teaser rates. The final number depends on what the camera shows and what you approve in writing before work starts. No per-vent pricing, no add-ons after the fact. Call (346) 423-3631 for an exact quote, estimates are free.
Why Spring Homeowners Call CleanRun Air Duct Cleaning Spring for Guardsman Work
We’ve logged a lot of hours in Spring, including plenty of calls out near Gleannloch Farms where the older construction and clay-heavy soil push surprising debris loads into return air plenums. Our crew knows the difference between a GDS and GDH failure pattern before we open the attic hatch. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we carry Lennox, Trane, and Carrier parts on the truck too, because mixed-brand systems are common in Spring homes built during the 2015-2020 construction wave.
The 365-Day Done Right Promise means if a sealed joint opens up or a replaced flex run fails, we make it right without a service fee. The photo record from every visit lives in your job file, not our marketing folder. And the price you approve in writing is the price on the invoice, every time, under Haven Standard Clause 1.
FAQs
No, independent duct repair does not void your HVAC system warranty, but Guardsman’s original ductwork warranty, if any remains, only covers defects in materials or factory workmanship. As an independent Guardsman service provider, we document our repairs with photos and written scope so you have a clear record of what was done and when, which protects you if a warranty claim arises on the original equipment. Call (346) 423-3631 if you need help interpreting your warranty documents.
Guardsman OEM fittings and replacement duct sections typically ship in 5-10 business days, which is why we stock quality aftermarket alternatives from Abatement Technologies and Honeywell that match the pressure and temperature ratings of the original equipment. For most Spring homeowners, the aftermarket route gets the job done same-day with equivalent performance and our 365-Day Done Right Promise behind it. Call (346) 423-3631 to discuss options for your specific system.
Replace when the repair cost exceeds 40% of a new system’s installed price or when corrosion, mold, or insulation collapse affects more than 30% of the total ductwork. Repair when the damage is localized to one or two runs, the trunk line is sound, and your static pressure test shows the system can still deliver design airflow. We’ll show you the camera footage and run the numbers both ways before you decide. Call (346) 423-3631 for a free assessment.
You receive a documented photo record of every duct run, before and after, as a standard deliverable on every job, plus a written scope of work and a post-repair static pressure reading. If we sealed four joints, you’ll see four sealed joints. If we replaced a flex run, you’ll see the old material and the new. This practice has been standard since our first job in 2013. Call (346) 423-3631 and we’ll show you a sample job record.
Yes, mixed-brand installations are common in Spring, especially in homes built 2016-2020 where the builder spec’d Guardsman ductwork with a Lennox or Trane air handler. Our trucks carry fittings and transition components for all four brands, and our technicians are trained to match static pressure requirements across manufacturer lines. We document the compatibility check in your written scope. Call (346) 423-3631 to schedule.
