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.

AfterFast, Reliable Duct Sealing Across Manor
We dispatch our Duct Sealing crews to Manor from our Austin coordination office, and we know the route well enough to hit our arrival windows. If you’re in ShadowGlen, Lagos, or any of the newer subdivisions off US-290, you’ve probably got flexible ductwork running through a hot attic, and there’s a fair chance it was kinked or crushed during the original build. That’s not a guess. We’ve opened enough return chases in Manor to know the pattern. Call us at (361) 326-5060 for a free estimate, and we’ll show you exactly what your ducts look like inside before we quote a dollar.

HVAC Duct Sealing in Manor
HVAC Duct Sealing in Manor starts with understanding that your home’s flexible duct system was likely installed fast and inspected late, if at all. The job involves finding every leak point in your supply and return runs, then sealing joints, connections, and penetrations with mastic or foil-backed tape rated for HVAC use. In Manor, we rarely find ducts that just need a quick seal. There’s almost always a crushed flex run, construction debris, or both. A typical HVAC duct sealing job in Manor runs $450 – $850 for a whole-system seal after source removal, or $180 – $340 for localized repair of accessible sections. If you also need our Dryer Vent Cleaning in Manor, we can bundle both services on the same visit. We write the price down before we start, and it doesn’t move at the door.
Camera Inspection Before Sealing
We run a borescope through every flex run we can access. In Manor’s newer homes, this step catches kinks and crush points that sealing alone would only hide. You see the footage. We explain what it means. Then we quote.
Source Removal and Debris Clear-Out
Drywall dust and construction debris left in ducts at handover gets sealed in permanently if crews skip this step. We use Rotobrush rotary brush systems and Nikro negative-air machines to extract debris before any mastic goes on. Sealing a dirty duct traps the dirt behind the seal forever.
Duct Repair in Manor
Duct Repair in Manor often means replacing damaged flexible duct sections rather than patching them. Crushed flex, torn inner liners, and collapsed insulation can’t be sealed back to full function. The repair involves cutting out the damaged run, installing new flex with proper support and minimal bends, then sealing all connections with mastic. Typical duct repair in Manor runs $280 – $620 depending on accessibility and how many sections need replacement. We always inspect the full system, because one crushed run usually signals others nearby were routed the same way.
Attic Routing and Support Fixes
Flex ducts in Manor attics sag, kink, or get flattened against truss gussets when installers skip proper support straps. We rehang runs with appropriate spacing, eliminate sharp turns, and add insulation where the original wrap has compressed or torn.
Condensation and Mold-Damaged Sections
Hot attic air against cool conditioned air inside poorly insulated flex creates moisture. In Manor’s humid climate, that moisture feeds mold growth on the duct liner. We replace affected sections, improve insulation, and seal the new connections so the cycle doesn’t repeat.
Trusted Brands We Service in Manor
We carry professional-grade equipment and materials on every truck: Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and sealing products from Abatement Technologies and Guardsman. For filtration upgrades tied to sealing work, we stock Honeywell and Aprilaire media. These aren’t hardware-store tools. They’re the same systems commercial crews use, and we keep common sizes and materials stocked so Manor customers aren’t waiting on parts. If your system needs a specific fitting or collar size, we likely have it on the van.
Common Duct Sealing Problems We See in Manor Homes
- Crushed flex runs from fast-track installation. In Manor’s subdivisions like ShadowGlen and Lagos, flexible duct is frequently routed through tight attic chases and flattened against framing. Sealing over a kinked duct hides the restriction instead of fixing it. We find and replace the damaged section first.
- Construction debris sealed into new ducts. Drywall dust, wood scraps, and insulation scraps left in supply and return lines at handover get permanently trapped when crews seal without source removal. We extract debris before we seal.
- Condensation and mold in poorly routed attic flex. Sharp turns and hot attic runs promote moisture buildup on the duct liner. Sealing a damp duct traps the problem behind the seal. We address the moisture source before sealing.
- Disconnected or partially connected joints. The speed of construction in Manor’s growth phase means some joints were never fully secured. We find these with pressure testing and camera inspection, then seal them properly with mastic.
Pricing for Duct Sealing in Manor, TX

FAQs About Duct Sealing in Manor
Manor’s fast-track subdivisions were largely built on former Blackland Prairie farmland, and builders often installed flexible ductwork that was kinked or crushed during construction, with debris left inside at handover. A 2020 build in ShadowGlen or Lagos is actually more likely to need sealing than a 1990s home in older Austin, because the original installation quality was rushed. Call (361) 326-5060 for a free camera inspection and we’ll show you exactly what’s in there.
Yes. In Manor’s rapidly built subdivisions, flexible duct runs routed through hot attics with sharp turns trap condensation on the interior liner, which feeds mold growth that homeowners notice as musty odors when the system runs. The kink restricts airflow too, so the smell lingers because the air isn’t moving through properly. We replace the damaged section, address the moisture source, and seal the new connections. Call (361) 326-5060 to schedule an inspection.
Most sealing work in Manor is done through existing access points, register openings, and small service openings we cut and patch. If we find crushed flex that needs replacement, that section does require attic access, but we minimize disruption and patch any openings we make. We’ll explain exactly what access is needed before we quote. Call (361) 326-5060 for specifics on your home.
Manor’s hot, humid summers mean HVAC systems run nearly year-round, and the frequent spring storms rolling across the Blackland Prairie pull in dust and pollen that leaks around unsealed joints. Newer homes here also have tighter construction, so any duct leakage pressurizes or depressurizes the envelope more dramatically than in leakier older homes. The combination makes sealing more impactful for both energy bills and indoor air quality in Manor than in many older Austin neighborhoods.
The only reliable way is a camera inspection. We’ve found drywall dust, wood scraps, and insulation chunks in Manor homes from 2019 builds that looked clean from the register. If your system has never been cleaned since you moved in, and you notice reduced airflow or dust that returns quickly after cleaning, debris from construction is the likely cause. We extract it before sealing, so it doesn’t get trapped permanently. Call (361) 326-5060 for a free estimate.
