Manor’s housing stock tells a very specific story — one we’ve learned by working inside hundreds of homes from the original townsite near downtown to the master-planned communities stretching east of SH-130. The 2010s–2020s building boom that transformed Manor from a rural crossroads into Austin’s eastern suburb created an unusual concentration of production-built homes with identical ductwork aging in unison. Douglas and the Nova team have spent eight years tracking how our Duct Repair & Sealing work needs to adapt to that reality. Whether you’re off FM 973 near ShadowGlen, in Whisper Valley, or in one of the older ranch homes near downtown Manor, we know what your ducts are likely hiding and how to fix it properly.
Why Nova Air Duct Cleaning Service Austin Is Manor’s Preferred Duct Repair & Sealing Company
More than 1,255 homeowners have reviewed our work across the Austin metro, and that 4.9-star average reflects something Manor residents specifically value: Douglas Ross shows up as Lead Technician, not a dispatcher sending unknown crews. When you’re inviting someone into your attic to handle the system your family breathes through, accountability matters. Douglas and the Nova team have worked in Manor long enough to recognize the builder-grade mastic patterns in DR Horton, KB Home, and Lennar properties — we know where the failures start before we pull back the insulation.
Our response time to Manor is typically same-day or next-day because we’re based in Austin and run routes through 78653 regularly. We’ve resealed ducts in ShadowGlen, repaired flex runs in Presidential Meadows, and addressed metal trunk deterioration in pre-1980 homes near the original Manor townsite. That geographic range within one ZIP code tells you how varied the housing is — and why a one-size-fits-all approach fails here.
Eight years focused on one trade means we’re not HVAC generalists squeezing in ductwork between compressor replacements. We carry professional-grade Rotobrush and Nikro equipment specifically for duct agitation and debris removal, and we stock mastic sealant, foil tape, and replacement flex duct in our service vehicles to complete most Manor jobs without a parts run.
Our Duct Repair & Sealing Services in Manor
Mastic Sealant Application
Manor’s production-built homes from the 2010s–2020s were sealed at construction with quick-applied mastic that degrades rapidly under 140°F+ attic temperatures. In the ShadowGlen neighborhood off FM 973, we resealed the flex duct joints in a 2015 DR Horton home. The builder’s original mastic had cracked throughout, drawing in blown-in fiberglass and drywall dust from the attic. We applied Rotobrush agitation and new mastic sealant, restoring system pressure and stopping the debris infiltration. A typical mastic resealing job in Manor runs $280–$450 for a single-system home.
Flex Duct Repair
Flex duct is the dominant material in Manor’s newer subdivisions, and it’s failing in predictable patterns. The plastic inner liner cracks where it hangs across hot attic trusses, the insulation sleeve compresses at support straps, and the mylar outer jacket tears on sharp edges left by rushed installation. We replace damaged flex runs with properly sized, supported, and sealed new duct — not patches that fail again in two seasons. Flex duct repair in Manor typically ranges from $180–$340 per run, with whole-system replacement in larger two-story homes reaching $520–$780.
Metal Duct Repair
The smaller core of pre-1980 ranch and farmhouse properties near downtown Manor and along rural routes still relies on galvanized metal trunk-and-branch systems. These don’t crack like flex duct, but they rust at seams, separate at drive cleats, and accumulate decades of undisturbed debris that flex duct simply doesn’t have time to collect. We seal metal seams with proper mastic (not duct tape), replace rusted sections, and use mechanical fastening where the original installer relied on friction fit. Metal duct repair in Manor generally runs $220–$480 depending on accessibility and extent of corrosion.
Duct Insulation Replacement
Manor’s attic temperatures destroy duct insulation as thoroughly as they destroy seals. Compressed, torn, or moisture-damaged insulation lets conditioned air warm before it reaches your registers — or cool, in winter, though Manor’s heating season is brief. We replace damaged insulation with properly rated flex duct or wrap existing metal with fiberglass insulation and vapor barrier, sealed at all seams. Insulation work in Manor typically adds $150–$320 to a sealing job, or $340–$580 as standalone replacement in accessible attics.

Trusted Brands We Service in Manor
We work with the equipment and products that professional indoor air quality specialists rely on, not consumer-grade alternatives. Our service vehicles carry Honeywell and Aprilaire air quality components for integration with your HVAC system, and we use Abatement Technologies HEPA filtration during agitation work to protect your home’s air during the repair process. For sanitizing after debris removal, Guardsman treatments address biological growth without the residue issues of consumer spray products. We stock these parts locally for Manor customers, which means faster turnaround and no waiting on shipping when your system needs a specific component.
Common Duct Repair & Sealing Problems We See in Manor Homes
- Cracked mastic at flex duct takeoffs pulls in attic insulation and dust from rapid-build construction residue. The 2010s building boom meant crews worked fast; mastic was applied thin and often before attic temperatures had stabilized. Now, as those homes hit the 8–15 year mark, we’re seeing systematic failure across entire neighborhoods.
- Foil tape separation on trunk lines allows unfiltered attic air and cedar pollen to enter supply registers. Manor sits in the Blackland Prairie with open terrain to the north and west; December through February cedar (Ashe juniper) pollen loads are severe, and unsealed ducts draw that directly into your living space.
- Unsealed duct boots in townhomes and alley-load homes leak conditioned air directly into unconditioned attics. The tighter lot configurations in newer Manor developments often mean duct boots were installed with minimal access and even less attention to sealing the penetration point.
- Drywall dust and blown-in insulation debris from original construction still circulates in homes that never had initial cleaning. Technicians working the newer subdivisions east of SH-130 routinely find ducts still packed with this residue — a direct byproduct of Manor’s builder-boom growth pace, where homes were occupied before duct systems were properly cleaned.

FAQs — Duct Repair & Sealing in Manor
Manor’s rapid 2010s–2020s suburban boom produced thousands of tract homes with attic flex ducts that share the same build-date, so the entire community’s duct seals are degrading in unison under 140°F+ attics. The quick-applied mastic and foil tape used by production builders cures and cracks faster in Central Texas attics than in cooler climates, and the compressed construction schedules common during Manor’s growth meant many systems were never properly cleaned before occupancy. If your home was built between 2010 and 2020 in ShadowGlen, Whisper Valley, or similar communities, your ducts are likely in this failure window now. Call (833) 315-4216 for a free inspection.
Yes — properly sealed ducts typically reduce household dust accumulation by 30–50% by stopping the infiltration of attic particulates, construction residue, and outdoor pollen. In Manor specifically, where open Blackland Prairie terrain allows fine dust and cedar pollen to load attics heavily, unsealed ducts act as a direct pathway for that debris into your living space. Many Manor customers notice less dust on surfaces within two weeks of sealing. Call (833) 315-4216 to schedule an inspection and estimate — they’re free.
Yes — pre-1980 metal duct systems near the original Manor townsite require different techniques than flex duct: rust assessment at seams, mechanical fastening rather than tape reliance, and often significant debris removal from decades of accumulation. These systems can be durable if properly maintained, but unaddressed corrosion or separation at drive cleats wastes conditioned air and can harbor mold in low spots. We inspect metal systems with cameras before quoting, and we preserve functional metal rather than pushing unnecessary replacement. Call (833) 315-4216 for an assessment of your specific system.
Yes — we’ve completed duct sealing and repair jobs in both ShadowGlen off FM 973 and Whisper Valley, and we’re familiar with the builder-specific duct configurations, attic access points, and common failure patterns in these communities. The uniform construction in these neighborhoods actually helps us work efficiently: we know the typical mastic application points, the standard flex duct routing, and where the original construction shortcuts most often appear. Call (833) 315-4216 to schedule service in your community.
Yes — sealed ducts block the infiltration of cedar pollen (December–February), live oak pollen (spring), and grass pollen (fall) that enters Manor homes through attic leaks, significantly reducing indoor allergen loads during peak seasons. Manor’s open terrain and constant Central Texas winds make outdoor pollen particularly aggressive here compared to more sheltered urban areas. For households with allergy sufferers, we often recommend combining duct sealing with air quality upgrades using Honeywell or Aprilaire filtration. Call (833) 315-4216 to discuss options for your home.
