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 Repair & Sealing Across New Territory
Duct repair and sealing in New Territory typically costs $280-$720 for most single-family homes, with flex duct replacement running higher when multiple runs have collapsed. Our crews are dispatched from our Houston office and serve New Territory directly, carrying the same Rotobrush and Abatement Technologies equipment we use on every job. We’ve worked the cul-de-sac clusters off New Territory Boulevard and the streets running toward the Brazos River corridor long enough to know what we’ll find before we open the attic hatch. Call (346) 666-7165 for a written estimate - no “call for pricing,” just a flat number delivered before any work starts.
Why CleanRun Air Duct Cleaning Katy Is New Territory’s Preferred Duct Repair & Sealing Company
We’ve been in New Territory homes since 2013, and the pattern is unmistakable. The same builder-grade flex duct failures - disconnected trunk takeoffs above master bedrooms, collapsed inner liners in long attic runs - show up on street after street because this entire master-planned community was built out in a compressed window with nearly identical HVAC layouts.
Our reputation here is built on documentation, not promises. Every job concludes with a Duct Repair & Sealing photo record showing the inside of every duct run before and after work. New Territory homeowners receive that record as a standard deliverable, not an upsell. Tomas Reyes established CleanRun on the principle that a customer should see what was wrong before paying to fix it.
Calls are answered by a live person, 24/7, and our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Scheduling is coordinated from our Houston office, with crews serving New Territory locally.

Our Duct Repair & Sealing Services in New Territory
Flex Duct Repair
This is the service we perform most often in New Territory. The original flex duct installed in the 1990s and early 2000s has spent 25-35 years in attics that regularly exceed 140°F. The insulation wrap degrades. The inner liner collapses. The vapor barrier cracks. On a slab home off New Territory Boulevard, our crew set up negative pressure and HEPA filtration during a routine clean, and camera inspection showed the original builder-grade flex run above the master bedroom had separated at the trunk takeoff, dumping conditioned air straight into a 140°F attic. We reattached the run, replaced the collapsed inner liner on the long west-side attic run, and sealed every joint with mastic, then confirmed static pressure at the air handler returned to normal. Flex duct repair in New Territory typically runs $320-$580 per run, depending on length and accessibility.
Mastic Sealant Application
Brush-on mastic is the only sealant we use on metal joints and repaired flex connections in New Territory. Tape fails in Fort Bend County’s attic heat; mastic remains flexible and airtight. We apply it to every trunk takeoff, every collar connection, and every repaired seam. A full mastic seal on a typical New Territory slab home’s metal trunk and plenum connections runs $280-$420. The work is photographed before and after, and the static pressure reading at the air handler is recorded in your job file.
Air Leak Repair
Disconnected ducts are not “a little leaky.” A separated trunk takeoff dumps 20-30% of conditioned air into the attic, which is why master bedrooms in New Territory often stay hot while the thermostat reads 72°F. We repair the disconnection, support the run with proper strapping to prevent re-sag, and verify airflow at the register with a digital anemometer. Air leak repair in New Territory is typically $180-$340 for a single disconnected run, $480-$720 for multiple points.
Duct Insulation
When the original insulation wrap on flex duct has degraded past recovery, we replace the run with new R-8 insulated flex or apply a duct insulation jacket to accessible metal trunk lines. In New Territory’s attics, where summer temperatures cook the original R-4 or R-6 wrap to brittleness, upgraded insulation pays for itself in reduced runtime. Duct insulation work ranges $380-$640 depending on linear feet and whether the plenum (the main distribution box attached to your air handler) also needs attention.
Metal Duct Repair
Some New Territory homes - particularly those built in the earliest phase near the community’s western edge - have galvanized metal trunk lines with spot rust or separated seams. We cut out damaged sections, fabricate replacements, and seal with mastic. Metal repair runs $340-$620 depending on extent and access.

BeforeAfterTrusted Brands We Service in New Territory
Our trucks stock parts and materials from trade-recognized brands: Rotobrush for duct cleaning and camera inspection, Abatement Technologies for HEPA containment, Aprilaire for filtration upgrades, and Guardsman for sealants and adhesives. We don’t ask New Territory homeowners to trust a generic “professional-grade” claim. These are manufacturer names you can look up independently, and they’re listed on your written scope before work begins. Because we dispatch from our Houston office with fully stocked vehicles, most New Territory repairs don’t wait on parts.
Common Duct Repair & Sealing Problems We See in New Territory Homes
- Original flex duct sagging and pooling condensation. The 1990s-to-early-2000s builder-grade flex in New Territory attics has endured decades of 140°F+ heat cycles. The support strapping loosens, the duct sags between joists, and low points collect condensation in Fort Bend County’s 75-90% relative humidity. That moisture drives mold and dust-mite colonization.
- Disconnected trunk takeoffs above master bedrooms. Because a handful of large builders used nearly identical floor plans across New Territory, the same layout quirk repeats: the flex run to the master bedroom connects to the trunk at a stressed angle, works loose over years of thermal expansion, and separates completely. Conditioned air dumps into the attic. The bedroom stays hot. The electric bill climbs.
- Collapsed inner liners in long attic runs. The inner plastic liner of old flex duct becomes brittle and tears, allowing the fiberglass insulation to bunch up and the airflow path to collapse. This is especially common in the long west-side attic runs found in many New Territory plans, and worse in homes near the Brazos River corridor where ground moisture infiltration adds load.
- Harvey-era moisture never remediated. Hurricane Harvey’s 2017 flooding impacted many Fort Bend County homes. Return-air systems and attic ductwork in New Territory took on moisture that was often dried at the surface but never professionally treated. We still find rust-stained metal, degraded flex liners, and active mold in homes where the owner never connected the 2017 flood to their current air quality issues.

FAQs - Duct Repair & Sealing in New Territory
Because your home was likely built in the 1990s or early 2000s with builder-grade flex duct that has now endured 25-35 years of Fort Bend County attic heat exceeding 140°F. The thermal expansion and contraction cycles stress every connection, and the original support strapping has loosened or broken. In New Territory specifically, the identical HVAC layouts used by the community’s handful of builders mean the same stressed-angle trunk takeoffs fail repeatedly, especially above master bedrooms. Call (346) 666-7165 and we’ll show you the exact failure point on camera before quoting a repair.
Musty odor when the AC runs, aggravated allergies in household members, or visible debris at registers are common indicators. In New Territory’s climate, sagging flex duct with pooled condensation is the primary driver - the combination of 75-90% relative humidity and extreme attic heat creates ideal conditions. Our camera inspection shows the interior condition directly; we don’t guess. If mold is present, we document it photographically and include remediation options in your written scope. Call (346) 666-7165 for an inspection.
Yes. Harvey’s 2017 flooding introduced moisture into return-air systems and attic ductwork throughout Fort Bend County. Many New Territory homes were dried at the surface level but never had ductwork professionally inspected or remediated. We still find rust-stained metal, degraded flex liners, and active mold in homes where owners never connected the 2017 flood to current air quality or efficiency problems. A camera inspection reveals whether your system was affected. Estimates are free - call (346) 666-7165.
New Territory was built out in a compressed late-1980s-to-early-2000s window by a handful of large builders using nearly identical HVAC layouts. The same flex duct failure points - disconnected trunk takeoffs above master bedrooms and collapsed inner liners in long attic runs - repeat house after house across the subdivision’s cul-de-sac clusters. A repair on one street usually predicts the exact failure a neighbor will call about next. Our crews recognize the patterns by floor plan. Call (346) 666-7165 and we’ll know what to inspect before we arrive.
We arrive at the scheduled time, identify ourselves by name, and begin with a camera inspection of every accessible duct run. You see the footage in real time.
