AfterFast, Reliable Duct Repair & Sealing Across Manor
Duct repair and sealing in Manor, TX typically runs $280-$680 for most residential jobs, with flex duct reconnection and mastic sealing at the lower end and full multi-run replacement in unconditioned attics at the higher end. Our crews are dispatched from the Austin office and carry full inventories of flex duct, support hangers, and mastic sealant so most Manor repairs finish in a single visit. Call (737) 243-9544 and we’ll put a written price in your hand before any panel comes off.
Manor isn’t a city of aging houses. It’s a city of new houses aging wrong. The 2000s-2020s tract homes in ShadowGlen and neighboring subdivisions were built fast, with builder-grade flex duct strung through attics that hit 140°F for months each summer. We’re the company that shows you the photo of what that actually looks like inside your ductwork, then hands you a written scope and a written price before touching a tool.
Why CleanRun Air Duct Cleaning Austin Is Manor’s Preferred Duct Repair & Sealing Company
We’ve worked in enough Manor attics to know the failure pattern by heart. It’s not rusted metal trunks or asbestos wrap, the problems our Austin mentors dealt with in 1980s builds. In Manor, it’s flex duct that has sagged off its hangers, insulation wrap that has cooked to powder, and boot collars that have worked loose after thousands of thermal expansion cycles. That specificity matters because a technician who expects old-house problems will miss new-house failures entirely.
Tomas Reyes established CleanRun in 2013, and our crews have documented photo records from over 52,000 homes since. Every Manor job starts with a written price under Haven Standard Clause 1 and ends with a photo record of every duct run, delivered as a standard deliverable. Our 365-Day Done Right Promise is backed in writing, not subject to manager approval. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.

Our Duct Repair & Sealing Services in Manor
Flex Duct Repair
Flex duct is the dominant material in Manor homes, and it’s where we spend most of our time. The corrugated plastic inner liner, wrapped in fiberglass insulation and a vapor barrier, was never designed to hang unsupported across 140°F attics for fifteen years. We find sagging runs that have pulled their own weight off boot collars, insulation wrap that has degraded to the point the R-value is gone, and sections crushed by storage or foot traffic during HVAC service. Our repair includes proper support hangers spaced to manufacturer spec, reconnection with mechanical fasteners, and mastic sealant at every joint. The photo record shows you the before sag and the after support.
Duct Sealing
Sealing is the corrective work that follows diagnosis. In Manor’s fast-built homes, we routinely find that duct tape - the cloth-backed adhesive used at builder handover - has dried to a brittle residue that flakes off at a touch. The remaining leaks pull unconditioned attic air into the system, or worse, dump conditioned air into spaces that don’t need it. Our Duct Repair & Sealing team uses mastic sealant, a water-based compound that remains flexible across temperature extremes, applied with a brush or caulk gun to every joint, seam, and penetration. For larger gaps, we reinforce with fiberglass mesh embedded in mastic. The result is a sealed system that holds its static pressure test.
Metal Duct Repair
Metal ductwork is rare in Manor’s housing stock but appears in some custom builds and in the main trunks of larger systems. Where we encounter it, the issues are typically seam separation at the drive cleats or corrosion at condensate contact points. We repair with sheet metal screws and mastic, or section replacement using snap-lock duct and proper S-cleat connections. The same photo documentation applies; the same written price precedes the work.
Duct Insulation
When flex duct insulation has cooked to the point that the vapor barrier is delaminating and the fiberglass is exposed, repair isn’t enough - the run needs replacement with properly insulated new material, or in some cases, external insulation wrap for accessible metal trunks. In Manor’s attics, we specify insulation rated for the temperature range actually encountered, not the theoretical number. The photo record documents the degraded R-value before and the restored thermal boundary after.
Mastic Sealant Application
Mastic isn’t a brand name; it’s a category of sealant that the trade has settled on as the correct material for duct joints. Unlike tape, it doesn’t dry out. Unlike aerosol sealants, it allows visual verification of coverage. Our technicians apply mastic to a thickness that obscures the underlying material, per SMACNA guidelines, and the photo record captures that coverage. In Manor’s dust-heavy environment, a sealed duct system doesn’t pull infiltration from wall cavities and attic spaces; it moves only the air the blower is designed to move.

Common Duct Repair & Sealing Problems We See in Manor Homes
- Flex duct fully disconnected from boot collars. In ShadowGlen and similar Manor subdivisions, thermal expansion cycles in 140°F+ attics work the flex-to-boot joint loose over 5-15 years. The system runs, but conditioned air dumps into the attic while negative pressure in living spaces pulls in unfiltered Blackland Prairie clay dust. We find this by camera inspection, not by guesswork.
- Sagging flex duct between widely spaced hangers. Builder crews often hung flex with minimal support, allowing the material to develop low points where condensation collects and insulation compresses. The sag worsens over time, restricting airflow and accelerating joint failure.
- Failed duct tape at every register boot. The adhesive used at builder handover dries and embrittles in Manor’s attic heat. By year ten, it’s common to find tape residue hanging in strips while the joint beneath gapes open. Mastic sealant is the permanent repair.
- Construction dust loading in newer homes. Manor’s ongoing expansion means finished homes sit adjacent to graded lots. Fine clay particulate infiltrates through construction gaps in fast-built envelopes, packing duct runs and blower motors before the home is even a few years old. Sealing the duct system reduces the negative pressure that drives this infiltration.
Pricing for Duct Repair & Sealing in Manor, TX
| Service | Typical Range in Manor |
|---|---|
| Single flex duct reconnection and mastic sealing | $280-$380 |
| Multi-run flex duct repair with hanger replacement | $420-$580 |
| Full attic system assessment with sealing of accessible joints | $480-$680 |
| Duct insulation replacement (per run, materials included) | $220-$340 |
These ranges reflect Manor’s market specifically. What moves a job toward the higher end: multiple disconnected runs, degraded insulation requiring replacement, or restricted attic access that extends labor time. What keeps it lower: single-point failures with good access and intact surrounding material. We don’t do per-vent pricing or teaser coupons that balloon once the truck arrives. Haven Standard Clause 1 requires a written, flat price per system before any work starts. Call (737) 243-9544 for a free estimate - we’ll inspect, photograph, and quote in the same visit.

FAQs - Duct Repair & Sealing in Manor
Because “new” and “correctly built” are different things. Manor’s 2000s-2020s tract homes were constructed rapidly with builder-grade flex duct in unconditioned attics that exceed 140°F. Thermal expansion cycles work joints loose within the first decade, and minimal support hangers allow sagging that accelerates failure. The system appears to run fine while quietly dumping conditioned air into your attic. Call (737) 243-9544 and we’ll camera-inspect to show you the actual condition.
Adjacent construction on Manor’s expanding subdivisions generates fine Blackland Prairie clay dust that infiltrates through gaps in fast-built envelopes. Negative pressure from leaky duct systems pulls that dust directly into the airflow path. The builder’s final cleaning was likely a surface vacuum, not source removal from the duct runs themselves. We document the dust load photographically, then remove it with agitation tools and HEPA negative-pressure extraction.
Three things: proper support hanger spacing to prevent flex sag; mastic sealant instead of duct tape at all joints; and a post-construction source removal cleaning before occupancy. None of these are exotic requests - they’re standard in SMACNA guidelines and the ENERGY STAR Version 3 checklist. Many Manor builders skipped them to meet schedule and price points.
We run a borescope camera through every accessible duct run from the register or plenum end. The image shows the disconnection directly - a collar with no flex attached, or flex terminated in open attic space. We also measure static pressure at the air handler and compare it to design spec; a significant drop indicates leakage. The photo record becomes part of your job documentation.
Yes, by removing the negative pressure that pulls infiltration through wall cavities, attic hatches, and construction gaps. A sealed duct system moves only the air the blower is designed to move, from the return to the supply, without drawing unfiltered exterior air into the path. In Manor’s clay-dust environment, that pressure balance is the single most effective step after physical source removal.
