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.

AfterAbatement Technologies Duct Repair & Sealing in Littleton: What to Know First
We provide independent Abatement Technologies duct repair and sealing in Littleton, with most residential jobs completed in a single scheduled visit and a written price delivered before any panel comes off. As an independent Abatement Technologies service provider, we carry OEM and quality aftermarket parts for the PREDATOR 750 and HEPA-AIRE lines most common in Littleton homes built between 2015 and 2020. Our typical Abatement Technologies duct sealing job runs $340-$680 for a full system, flex duct repair runs $180-$420 per run, and every quote is fixed in writing under Haven Standard Clause 1.
This page is for Abatement Technologies owners in Littleton, Columbine Knolls, and the Ken Caryl Valley area who have noticed uneven airflow, dust at registers, or utility bills climbing without explanation. If your Abatement Technologies system is connected to ductwork that’s leaking, crushed, or pulling attic air, the equipment is working harder than it should. Call (720) 315-7291 and we’ll send a written estimate you can compare against any other.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 750 series: plenum seal degradation at the flex-to-metal transition. The 750’s high-static blower creates more pressure at the plenum connection than standard residential units, and after 6-10 years in Littleton’s dry climate the mastic sealant cracks rather than flexes. We remove the old sealant back to bare metal, apply fresh mastic rated for the 750’s operating temperature, and mechanical-fasten the flex with a draw-band plus UL-181 tape. The camera shows the gap before we quote; the camera shows it sealed before we leave.
- HEPA-AIRE portable units: negative-pressure duct collapse in older flex runs. These units pull harder than most portables, and in Littleton’s Columbine Knolls neighborhoods where ducts date to the 1980s, we’ve found the internal wire helix on flex duct has fatigued. The symptom is a whistling drop in suction at the far register. We replace the collapsed section with reinforced flex rated for negative-pressure extraction, support it with proper hangers every 4 feet, and test static pressure before and after.
- Abatement Technologies PAS2400 pre-filters: bypass air through unsealed filter racks. The PAS2400’s filter rack is a common retrofit in Littleton homes, and installers sometimes leave a 1/4-inch gap at the rack perimeter. Conditioned air bypasses the filter, loads the coil, and pressurizes the return plenum until seams leak. We seal the rack with closed-cell gasket, verify zero bypass with a smoke pencil, and photograph the seal line for the job record.
- Abatement Technologies AbatementVac HEPA: duct insulation failure at roof penetrations. In Littleton’s hail-prone spring season, we’ve found the AbatementVac’s connection duct on roof-mounted jobs where the insulation jacket has separated from the vapor barrier. The fix is stripping to bare duct, replacing with fiberglass insulation at the correct R-value for Colorado’s climate zone, and sealing the jacket with ASJ tape - not duct tape, which fails in attic heat.
- Abatement Technologies CADPXS commercial dehumidifier lines: supply duct condensation drip. When these units are paired with uninsulated metal supply in Littleton’s summer monsoon pattern, cold air hits warm duct and sweats. We wrap the affected runs with closed-cell insulation, seal all seams, and install a condensate drain pan where the geometry traps moisture. The photo record shows the drip path before, the dry surface after.
Our Abatement Technologies Duct Repair & Sealing Process
- 1
Inspection with camera and static-pressure test. We run a borescope through every accessible duct run and take pressure readings at the plenum and the farthest register. Tomas Reyes pulls the inspection camera before quoting anything. The camera doesn’t negotiate - it just shows what’s there.
- 2
Written scope and price, delivered on site. Haven Standard Clause 1: one flat price per system, agreed before work starts. No per-vent pricing, no add-ons once the truck is open.
- 3
Parts decision: OEM Abatement Technologies or verified aftermarket. For plenum connections and filter racks we prefer OEM; for flex duct and insulation we use quality aftermarket that meets or exceeds manufacturer spec. We tell you which we’re using and why.
- 4
Repair and seal per Abatement Technologies static-pressure requirements. Every seam gets mastic or UL-181 tape, every flex joint gets a draw-band, and we verify no leakage with a smoke test or digital manometer.
- 5
Post-repair pressure test and photo documentation. We match pre- and post-repair static pressure, photograph every sealed joint and replaced run, and deliver the record as a standard job deliverable.
- 6
365-Day Done Right Promise in writing. If the seal fails, the pressure drops, or the symptom returns, we make it right. The promise is printed, not implied.

FAQs
No, independent duct sealing and repair does not void your Abatement Technologies equipment warranty, provided the work does not alter the unit’s electrical or refrigerant systems. We seal ducts, replace flex, and repair plenums - none of which touches the equipment warranty. We document exactly what was done so there’s no dispute if a separate equipment claim arises. Call (720) 315-7291 if you need the documentation format for your warranty file.
Static pressure testing tells the difference in about 10 minutes. If the blower is generating rated pressure but airflow at the register is weak, the leak is in the duct. If pressure is low at the plenum, the issue is likely the unit. We run this test before quoting any work. Call (720) 315-7291 and we’ll show you the numbers.
We stock OEM plenum adapters, filter racks, and transition fittings for the PREDATOR and HEPA-AIRE lines. For flex duct, insulation, and standard sealants we use aftermarket that meets UL-181 and SMACNA standards - often the same material, without the branded markup. We tell you which we’re proposing before you agree to the price.
Replace if the ductwork is galvanized steel with widespread corrosion, if asbestos wrap is present, or if the original design cannot support your Abatement Technologies unit’s airflow requirements. Repair if the damage is localized to a few runs, seals, or insulation sections. We’ve found that most Littleton homes built after 1990 fall into the repair category. We’ll show you the camera footage and give you both numbers if you’re unsure.
Most residential jobs are completed in 3-5 hours for sealing, 4-6 hours if flex replacement is involved. We schedule a specific arrival window, not an all-day wait. The crew identifies themselves by name before arrival, and you’ll have the photo record and written invoice before they leave. Call (720) 315-7291 to book a slot that works for your schedule.
