We’ve been driving out to Manor since the early days of Shadowglen’s build-out, and we know the housing stock here better than most. From the original tract homes off FM 973 to the newer geothermal developments near US-290, our Duct Repair & Sealing crews make the trip from Houston with the right materials already loaded. That means no waiting on parts, no return visits for forgotten fittings, and a job that’s finished when we say it will be.
Why Bellows Air Duct & Vent Co. of Texas Is Manor’s Preferred Duct Repair & Sealing Company
Forty-two years in this business teaches you that Manor isn’t Austin, and it isn’t Elgin either. The homes here were built fast during the affordability boom, and the ductwork shows it. We’ve repaired enough 2008-era flex duct in Shadowglen to know where the builder shortcuts typically hide: undersized trunks, unsealed collar connections, and mastic that gave up before the first mortgage was paid off.
Our technicians are background-checked, uniformed, and trained to spot the difference between normal wear and the kind of failure that wastes thirty percent of your cooling bill. Every job starts with a camera inspection - you’ll see the damage before we touch a tool - and ends with a second camera pass proving the repair holds. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no arguing about whose fault it was.
Calls to our office reach a live person, 24 hours a day. Not a voicemail tree, not an app. When a Manor homeowner calls at 6 p.m. because the upstairs won’t cool below 82°F, someone answers who can dispatch a crew or schedule you for tomorrow morning.
Our Duct Repair & Sealing Services in Manor
Duct Sealing
Most Manor homes lose 20 to 30 percent of conditioned air through leaks at joints, seams, and connections. In the tract homes built during the 2003-2010 rush, we find mastic sealant that cracked within a decade - sometimes within five years - because attic temperatures in Manor regularly climb past 130°F in July and August. We seal with professional-grade mastic compounds rated for sustained high heat, then pressure-test the system to verify the fix. A typical duct sealing job in Manor runs $350-$550 for a single-zone system.
Flex Duct Repair
Flex duct is the standard in Shadowglen, Presidential Meadows, and most of the 78653 master-planned communities. The plastic liner degrades. The insulation compresses. The wire helix corrodes where condensation collects. In Shadowglen, we found a 2008 builder-grade flex duct that had sagged and torn at the trunk connection, leaking conditioned air into the attic during 130°F summers. We replaced the damaged section with R-8 insulated flex, sealed all joints with Honeywell mastic, and re-insulated the exposed trunk - the homeowner saw a 5°F drop in upstairs temperatures the same day. Single flex run replacement in Manor typically costs $180-$340.
Metal Duct Repair
Older Manor homes and some custom builds use galvanized steel ductwork. The metal itself lasts, but the connections don’t - especially in Manor’s clay-soil environment. Foundation movement from seasonal swelling and contraction cracks seams at slab penetrations and wall stacks. We cut out damaged sections, fabricate replacement pieces on-site, and seal with mastic and mechanical fasteners that can flex without failing. Metal duct repairs in Manor generally run $280-$480 depending on accessibility.
Duct Insulation
When attic insulation gets stripped away by rodents, compressed by maintenance traffic, or cooked brittle by years of 130°F heat, your ducts lose temperature before the air reaches the room. We reinsulate with foil-faced fiberglass wrap or closed-cell foam where appropriate, restoring the thermal barrier that builder-grade installations often skimped on. Full attic duct reinsulation in Manor typically costs $450-$850 based on linear footage and access difficulty.

Trusted Brands We Service in Manor
We stock Rotobrush inspection cameras and Nikro HEPA equipment on every truck, and we specify Honeywell mastic sealants and Aprilaire filtration components for repairs where material quality matters. For Whisper Valley’s geothermal systems, we carry pressure gauges and low-static adapters that standard duct service trucks don’t have - because standard equipment can over-pressurize those ducts and blow seals that were never designed for conventional blower force. Parts availability means most Duct Repair & Sealing in Manor jobs finish in a single visit, not two or three.
Common Duct Repair & Sealing Problems We See in Manor Homes
- Attic heat destroys flex duct liners. Manor’s attic temperatures exceed 130°F for weeks each summer, baking the plastic inner liner of flex duct until it cracks and tears. We replace the damaged runs with R-8 insulated flex rated for higher temperature exposure, then verify with camera inspection.
- Clay-soil foundation movement cracks metal connections. The Blackland Prairie’s expansive clay swells in wet seasons and shrinks in drought, shifting slab-on-grade and pier-and-beam foundations enough to separate duct seams at floor penetrations. We repair with flexible joint connections that absorb movement without reopening.
- Builder-grade mastic fails prematurely. The mastic applied during Manor’s 2003-2010 construction boom was often thin, poorly mixed, or applied to dusty surfaces. It cracks within 10-15 years. We remove the old material entirely and reseal with fresh, properly prepped compound.
- Whisper Valley’s low-static ducts require specialized handling. Standard duct-cleaning blowers and even some repair tools can over-pressurize the ultra-low-static ductwork tied to EcoSmart geothermal air handlers. Our crews run a separate truck setup for Whisper Valley with pre-job pressure verification.

FAQs - Duct Repair & Sealing in Manor
Most 2008 Shadowglen flex ducts are at or past their reliable service life. The original builder-grade liner and mastic were never rated for 15 years of 130°F attic exposure. We camera-inspect first - if the liner is cracked, the insulation compressed, or the connections sagging, replacement is usually more cost-effective than patching. Call (866) 347-2063 to schedule an inspection; estimates are free.
Yes, but only with the right equipment. Whisper Valley’s EcoSmart geothermal air handlers run ultra-low static pressure through ductwork that standard tools can over-pressurize. Our crews bring a separate truck setup for Whisper Valley with pre-job pressure verification and low-flow adapters. We’ve repaired dozens of these systems without a single seal failure. Call (866) 347-2063 and mention your Whisper Valley address when you book.
Manor’s Blackland Prairie clay expands when wet and contracts in drought, shifting foundations enough to crack metal duct seams at slab penetrations and wall stacks. We see this most in slab-on-grade homes built during the 2005-2012 period. Our repairs include flexible joint connections that absorb this movement without reopening. If your home has recurring leaks at the same locations, foundation movement is likely the cause - call (866) 347-2063 and we’ll show you on camera.
Yes. Attic insulation on flex duct compresses, degrades, or gets stripped away by rodents and maintenance activity over 15-20 years. We remove the damaged wrap, inspect the duct beneath for liner cracks, then re-insulate with foil-faced fiberglass or closed-cell foam depending on your attic configuration. Most reinsulation jobs in Manor run $450-$850 and are completed in one visit. Call (866) 347-2063 for an exact quote.
We specify Honeywell professional-grade mastic compounds rated for sustained high-heat exposure - critical in Manor’s 130°F attics. For repairs requiring additional mechanical reinforcement, we use Nikro and Rotobrush application equipment to ensure complete, uniform coverage without gaps or thin spots. The brand matters less than the preparation: we remove old failed mastic entirely and clean the joint surface before applying new material. Call (866) 347-2063 if you want to see the product data sheet before we start.
