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 Irving: What to Know First
We provide independent Guardsman duct repair and sealing in Irving, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. Typical turnaround from inspection to completion runs same-day to 48 hours depending on parts availability, and every job carries our 365-Day Done Right Promise in writing. This page is for Irving homeowners who own Guardsman duct components and need actual repair work - sealing, flex section replacement, metal restoration, or insulation repair - not a coupon vacuum job. Call (682) 297-4068 for a free written estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman Flex-Pro Series collapses at radius elbows. The Flex-Pro’s spiral wire helix fatigues faster than competing brands when subjected to Irving’s summer attic temperatures, which regularly exceed 140°F. We replace the collapsed section with a Guardsman-compatible flex duct rated for higher static pressure, or source OEM Flex-Pro when the run length and fitting geometry demand exact replacement.
- Guardsman Rigid Round develops seam separation at plenum connections. The Rigid Round line uses a lighter-gauge metal at the collar joint that works loose under seasonal thermal expansion. We reseat the collar with mastic sealant and mechanical fasteners, then pressure-test to verify the seal holds under operating load - not just at rest.
- Guardsman Insul-Tube loses its vapor barrier in humid attics. Irving’s spring and fall humidity cycles degrade the foil facing on older Insul-Tube runs, leading to condensation inside the insulation blanket and mold-like growth on the duct liner. We strip the compromised section, inspect the underlying duct for corrosion, and install new insulated flex with a intact vapor barrier - photographing the condition of the liner before any replacement begins.
- Guardsman Snap-Lock oval flattens under negative pressure from oversized equipment. When a replacement HVAC unit pulls harder than the original design spec, Snap-Lock oval ductwork deforms at the long-axis seam. We reinforce with internal supports or transition to round rigid duct where space allows, calculating the static pressure change so the repair doesn’t create a new restriction downstream.
- Guardsman register boots pull away from drywall. The mounting flange on standard Guardsman register boots is narrower than competing designs, making it prone to separation when the duct behind it shifts. We resecure with extended fasteners and seal the gap with fire-rated mastic, then verify airflow at the register with a calibrated anemometer - the reading goes in your job record.
Our Guardsman Duct Repair & Sealing Process
- 1
Inspection with photo documentation. We run a camera through every accessible duct run and photograph the failure point. The photo doesn’t lie - let’s look at it together before we talk about next steps.
- 2
Written scope and price. Haven Standard Clause 1: we deliver a written price for the exact work required, with no per-vent pricing or open-ended labor rates. You approve in writing before we touch a tool.
- 3
Parts decision: OEM or verified aftermarket. For current Guardsman series, we source OEM when the warranty status or fitting tolerance demands it. For discontinued lines, we specify aftermarket equivalents from Abatement Technologies or Nikro with documented pressure ratings.
- 4
Repair and seal. Our crew executes the repair with professional-grade mastic, mechanical fasteners, and insulation restoration as needed. Every sealed joint is marked for later verification.
- 5
Pressure test and airflow verification. We test static pressure before and after the repair, and measure airflow at the register. The numbers go in your documented photo record.
- 6
Cleanup, record delivery, and warranty activation. You receive the complete photo record, the written scope, and the 365-Day Done Right Promise - all before we leave.
BeforeAfterWhat Guardsman Duct Repair & Sealing Costs in Irving
| Scenario | Typical Range |
|---|---|
| Single flex duct section replacement (Guardsman Flex-Pro or equivalent) | $340 - $580 |
| Rigid round seam repair with mastic seal and pressure test | $280 - $440 |
| Register boot resecure and seal (per location) | $160 - $240 |
| Insul-Tube replacement with vapor barrier restoration (per run) | $420 - $720 |
| Full duct sealing with Aeroseal-compatible mastic (whole system) | $1,800 - $2,800 |
Price moves with accessibility - attics with limited clearance in Las Colinas-era homes add labor time - and with whether the failure has caused secondary damage to the duct liner or surrounding insulation. We do not quote per-vent prices. One flat price per system, agreed in writing before work starts. Call (682) 297-4068 for a free written estimate.
Why Irving Homeowners Call CleanRun Air Duct Cleaning Irving for Guardsman Work
We’ve been running service calls throughout Irving, including the Las Colinas corridor, since establishing our DFW operation. Tomas Reyes grew up in the Bronx, picked up his HVAC fundamentals at Bronx Community College, and spent years doing hands-on duct work before bringing that approach here - inspection photos first, written summary of what was found, no shortcuts.
Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so when a Guardsman repair reveals an upstream equipment issue, we can diagnose it without calling in another contractor. Every job concludes with a Documented Photo Record - inside every run, before and after - and the 365-Day Done Right Promise backed in writing, not just stated in marketing copy.
FAQs
No - independent repair work on ductwork does not void HVAC equipment warranties, provided the repair does not alter the original equipment’s electrical or refrigerant systems. As an independent Guardsman service provider, we document every repair with photos and a written scope, which protects your warranty record if questions arise later. Call (682) 297-4068 if you need help interpreting your warranty documents.
Current-production Guardsman series under active warranty typically benefit from OEM parts for exact fit and warranty continuity. Discontinued lines, or components past the warranty period, often accept verified aftermarket equivalents with equal or superior pressure ratings - we specify the source and rating in writing before ordering. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman tools, so we can match the right component to your system.
Replace when the total repair cost exceeds 60% of a new system’s installed price, or when multiple failure modes indicate systemic deterioration - widespread corrosion, collapsed insulation throughout, or repeated seam failures in rigid duct. Repair when the failure is isolated to one or two runs and the remaining ductwork tests within spec for static pressure and leakage. We provide both numbers in writing so you can decide on evidence, not pressure.
Common Guardsman flex, fittings, and mastic sealant are available from our DFW-area suppliers within 24 hours. Specialty or discontinued components may take 48-72 hours. We confirm parts availability during your free estimate and schedule accordingly - no “we’ll show up and see what happens.”
We pressure-test the system before and after the repair, measure register airflow with a calibrated anemometer, and include both sets of readings in your Documented Photo Record. If the numbers don’t improve, we don’t call the job complete - Haven Standard Clause 1 applies to results, not just effort. Call (682) 297-4068 to schedule an inspection and see the documentation standard for yourself.
