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.
Abatement Technologies Duct Sealing & Repair: The Marietta Owner’s Guide
We stock and install Abatement Technologies-compatible duct sealing and repair components for homeowners in Marietta, with typical installed pricing between $340 and $780 depending on system reach and accessibility. Most calls we handle near Kennesaw Mountain and the 30062 corridor are completed same-day because we carry Abatement Technologies-compatible collar seals, flex-duct repair sleeves, and plenum gasket kits on every truck. Most owners realize something is wrong when a room never reaches the thermostat setpoint or their energy bill spikes 20% without explanation - the camera usually reveals separated joints or degraded seals that were invisible from the register.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds negative-air machines and containment equipment used in remediation and commercial settings, but their duct-sealing components - collar adapters, flexible duct connectors, and HEPA-compatible plenum gaskets - cross over into residential systems more often than people expect. If your HVAC contractor installed Abatement Technologies hardware during a mold remediation or renovation between 2015 and 2022, the labels are typically stamped on the collar flange or printed on a foil tag near the plenum connection.
We match by three things: collar diameter (6-inch, 8-inch, or 10-inch are standard for Abatement Technologies residential adapters), gasket material spec (silicone-impregnated fabric rated for 200°F continuous, or the cheaper EPDM that cracks after three Georgia summers), and whether your system uses the older bolted flange or the newer clamp-ring style introduced around 2019. The OEM gasket runs $45 to $80; we also stock a reinforced aftermarket equivalent from Guardsman that matches the temperature spec and carries the same 365-day warranty through our install. One compatibility gotcha: the 2017-2019 PRED750 series used a proprietary 7.5-inch collar that does not accept standard 8-inch repair sleeves without a transition piece. We fabricate those in the van.
Signs Your Abatement Technologies Duct Sealing & Repair Is Failing

- Uneven temperatures room-to-room. When a collar seal separates from the main trunk, conditioned air dumps into your attic or crawl space instead of reaching the register. The thermostat in the hallway reads 72°F while the back bedroom stalls at 78°F, and the system runs longer to compensate.
- Dust reappearing within 48 hours of cleaning. A failed plenum gasket pulls attic air through the gap every time the blower cycles. That air carries fiberglass particles, pollen, and in Marietta’s clay-heavy soil zones, fine red dust that coats registers within days.
- Whistling or rushing noise near the air handler. High-velocity air squeezing through a partial separation sounds like a persistent leak. The noise often worsens when the system shifts from heat to cool because thermal expansion changes the gap geometry.
- Energy bills climbing without rate changes. A 15% to 25% spike is common when 20% of conditioned air never reaches living space. We have photographed gaps in Abatement Technologies collar connections that were leaking the equivalent of a full register’s worth of air.
- Musty or chemical odor when the blower starts. A degraded flex-duct sleeve can pull vapor from a crawl space or garage return. In Marietta’s humid shoulder seasons, that moisture breeds mold on the gasket surface within a single summer.

AfterReplacement Cost & What’s Included
| Component | Parts Range | Installed Range |
|---|---|---|
| Collar seal / gasket replacement (single) | $45 - $85 | $340 - $480 |
| Flex-duct sleeve repair (per run, up to 15 ft) | $65 - $120 | $420 - $620 |
| Plenum gasket kit (full perimeter) | $80 - $140 | $520 - $780 |
| Clamp-ring transition (PRED750 7.5″ adapter) | $35 - $55 | $180 - $260 |
What drives the range: accessibility (attic vs. crawl space vs. finished basement ceiling), how many joints need resealing, and whether we find secondary damage - a separated collar often means the flex duct itself has pulled back and needs trimming. Every quote is written before work starts under Haven Standard Clause 1. The 365-Day Done Right Promise covers the repair and the seal integrity. We also leave you with a Documented Photo Record of every connection point, before and after.
DIY or Call Us?

There is nothing inherently dangerous about inspecting a duct seal - turn the system off, shine a light at the plenum connections, and look for gaps, blackened gasket residue, or collars that shift when you press them. What goes wrong is the repair itself. Attic work in July in Marietta is not the place to discover you bought the wrong gasket diameter, and a half-seated collar will leak worse than the original failure because the clamp distorts the flange.
We carry Abatement Technologies-compatible seals, the right clamp tools, and the transition pieces for odd sizes. The camera doesn’t lie - and neither does the invoice. If you are staring at a separated collar and wondering whether it is worth a trip to the supply house, call (470) 516-9337 and we will give you a written number you can compare against your Saturday.
FAQs
Silicone-impregnated gaskets typically hold 8 to 12 years in Marietta’s climate; EPDM versions often crack by year 4 due to attic temperature swings from 40°F winter nights to 140°F summer peaks. The red-clay dust common in Cobb County accelerates wear at the collar edge because airborne grit acts like sandpaper every time the joint flexes. Call (470) 516-9337 for an exact quote - estimates are free.
Temporary foil tape or mastic can slow a leak for a season, but it is not a repair. Once the gasket compresses or the flange warps, the joint will reopen because the mechanical connection is compromised. We do not apply temporary fixes because Haven Standard Clause 1 requires a written scope that solves the problem, not delays it. Call (470) 516-9337 for an exact quote - estimates are free.
A single collar seal or gasket swap takes 45 to 90 minutes; a full plenum perimeter with multiple flex-duct runs runs 3 to 4 hours. We photograph every connection before we start and again before we leave, so the time includes documentation, not just labor. Call (470) 516-9337 for an exact quote - estimates are free.
We carry compatible collar seals, gasket kits, flex-duct sleeves, and the 7.5-inch transition for PRED750 series units on every Marietta-area truck.
