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.

We’ve worked on enough homes off Fair Oaks Parkway and Boerne Stage Road to know the local pattern: multi-zone systems with 40-foot duct runs through unconditioned attic space, separated by decades of thermal cycling, and return-air grilles positioned exactly where cedar brush clearing kicks up dust clouds. That’s not a generic duct problem. It requires specific repair sequencing and materials.

Our Duct Repair & Sealing Services in Fair Oaks Ranch
Duct Sealing
Leaky trunk lines and joint separations are the dominant failure mode in Fair Oaks Ranch’s large estate homes. A typical duct sealing job here runs $340-$780 for partial-system work and $1,200-$2,400 for complete sealing on homes over 4,000 square feet. We use mastic sealant reinforced with fiberglass mesh at every joint, register boot, and plenum connection, then verify with a static pressure test. The goal is measurable: return the system to its designed airflow capacity, not just make it quieter.
Flex Duct Repair
Flex duct in Fair Oaks Ranch attics degrades from two directions: summer heat pushing 140°F in the roof cavity, and the physical stress of long unsupported spans across large homes. We regularly find sagging flex that has pulled free from collars, or insulation that has degraded and is dumping conditioned air into the attic. Repair runs $280-$650 per run depending on length and accessibility, with full replacement of deteriorated sections when patching won’t hold. We strap to code, not to convenience.
Metal Duct Repair
Older metal trunk lines in homes built during Fair Oaks Ranch’s 1990s development wave suffer from seam separation and corrosion at condensate contact points. Metal repair requires sheet metal patching, seal welding at accessible points, or sectional replacement when damage is extensive. Jobs range from $320 for localized seam sealing to $890+ for major trunk rehabilitation. We photograph the damage before recommending repair scope.
Air Leak Repair
Air leak repair in Fair Oaks Ranch homes often traces to a specific local cause: cedar brush clearing on the property sends ultrafine juniper dust toward low soffit and exterior-wall return-air grilles, where it infiltrates gaps in the building envelope and duct connections. We pressurize the system, locate leaks with smoke testing or thermal imaging, and seal at the source. Typical leak repair runs $380-$720. The work is verified with a post-repair pressure differential reading, documented in your job record.
Duct Insulation
When flex duct insulation has degraded in Fair Oaks Ranch’s hot attics, we replace with new R-8 insulated flex or apply closed-cell insulation to accessible metal runs. Insulation work runs $450-$980 depending on linear footage. This is often paired with sealing, since degraded insulation usually indicates long-term thermal stress that has also compromised joints.

Common Duct Repair & Sealing Problems We See in Fair Oaks Ranch Homes
- Cedar debris loading from brush clearing. Homeowners throughout Fair Oaks Ranch routinely clear Ashe juniper from their acreage, releasing clouds of fine gray-green dust that exterior-wall and soffit return-air grilles draw directly into the duct system. Technicians regularly find ductwork caked with a distinctive cedar debris layer that is essentially unseen in communities without large cedar-covered lots.
- Disconnected flex runs in long attic spans. The 3,000-6,000+ sq ft custom homes common here use multi-zone systems with duct runs that cross significant unconditioned attic distance. Thermal expansion, inadequate strapping, and rodent activity separate flex from collars, dumping conditioned air into the attic and starving downstream registers.
- Neglected detached systems. Guest casitas, pool houses, and equestrian structures with separate HVAC systems are often serviced years apart from the main house. Their ductwork develops independent leak points, filter loading, and pollen accumulation that the primary system service never addresses.
- Two-season accumulation cycle. Fair Oaks Ranch’s semi-arid Hill Country climate deposits dust from May through October, then the December-February mountain cedar bloom sends ultrafine pollen into the same ductwork during heating season. No other San Antonio suburb faces this specific combination at the same intensity.

Honest pricing means naming numbers before you commit. Here’s what duct repair and sealing costs in the Fair Oaks Ranch market:
| Service | Typical Range |

FAQs - Duct Repair & Sealing in Fair Oaks Ranch
Every 2-3 years for homes on acreage with active cedar management, and annually if you’re clearing brush during pollen season. The two-season accumulation cycle here, summer dust plus winter cedar pollen, loads ductwork faster than in San Antonio’s eastern suburbs where cedar density is lower. After a major brush-clearing event, schedule an inspection even if you’re inside the normal interval. Call (726) 600-7155 for a camera inspection and written estimate.
Because low soffit and exterior-wall return-air grilles are positioned exactly where brush-clearing dust clouds settle, and any gap in the building envelope or duct connection gives that dust a direct path into your system. Sealing the duct boot-to-wall connection and upgrading to a tighter filter frame often solves this. We document the infiltration path with a camera before recommending scope. Call (726) 600-7155 and we’ll show you exactly where the air is coming from.
Yes. We regularly service detached guest casitas, pool houses, and equestrian structures with independent systems. These are often neglected for years and develop their own leak points and pollen loading. We scope, photograph, and quote each system separately, with a written price for each before any work starts. The photo record covers every run in every building.
Camera inspection of every accessible run, identification of leaks and separations, repair or replacement of damaged flex or metal, mastic sealing at all joints and boots, strapping to code on long spans, static pressure verification, and a complete photo record delivered to you. On a 4,000+ sq ft home, this typically takes a full day. The written price covers the entire scope; no per-vent add-ons.
Yes, measurably. Leaky return ducts pull unfiltered air from attics and wall cavities; leaky supply ducts pressurize those same spaces and drive dust through every gap. Sealing returns the system to its designed filtration path. In Fair Oaks Ranch specifically, this also reduces the cedar dust that infiltrates during brush-clearing season. The effect is verifiable: compare your photo record and static pressure readings before and after.
What Makes Fair Oaks Ranch Different for Duct Repair & Sealing
Fair Oaks Ranch sits in the heart of Ashe juniper country, ground zero for cedar fever season running December through February, when airborne pollen counts reach extreme levels among the highest recorded in North America. Because heating systems run during this same window, return-air vents actively pull ultrafine Juniperus ashei pollen deep into ductwork. Then the summer AC season deposits months of Hill Country dust on top of it. San Antonio’s eastern and southern suburbs don’t face this two-season accumulation at the same intensity. It’s a distinctly local reality that shapes how we sequence repairs, what materials we specify, and why we recommend shorter inspection intervals for homes on managed acreage.
We got a call from a homeowner off Fair Oaks Parkway whose 4,200 sq ft home had a detached guest casita on its own air handler; both zones were blowing the same fine gray-green dust every time the heat kicked on. After a camera inspection found a separated flex run in the attic and three leaking trunk joints, we put the system under negative pressure with HEPA filtration, used agitation tools for source removal on the supply and return ducts, re-sealed the gaps with mastic and mesh, and strapped the sagging flex back to code. The cedar debris layer cleared, static pressure dropped, and the homeowner stopped seeing dust settle on the guest-house furniture within a week.
That’s the difference between documenting what we find and guessing from the truck. Our Duct Repair & Sealing team serves Fair Oaks Ranch with the same standard: written price first, photo record last, and every claim verifiable.
