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 Timberwood Park
Duct repair and sealing in Timberwood Park typically runs $340-$890 per system depending on access, damage extent, and whether insulation replacement is needed. Most homes here need multiple systems addressed, not just one. Call (830) 549-6847 for a written estimate before any work starts.
We dispatch crews to Timberwood Park from our San Antonio office, and we know the area’s homes well. The semi-custom Hill Country builds off Timberwood Park Road, the winding streets near the community’s wooded perimeter, and the larger floor plans throughout the subdivision share a common trait: multiple attic-run flex duct systems that take a beating from mountain cedar pollen, summer heat cycles, and the shaded, humid conditions that breed mold inside duct runs. Our Duct Repair & Sealing team treats Timberwood Park as a core service area, not an afterthought.

Our Duct Repair & Sealing Services in Timberwood Park
Duct Sealing
Timberwood Park homes lose conditioned air through joints, collars, and trunk takeoffs that separate under years of heat expansion. We seal with mastic sealant, not tape alone, because tape fails in unconditioned attics within a few seasons. A typical duct sealing job in Timberwood Park runs $340-$520 per system for accessible attic work, with written scope before we start.
Flex Duct Repair
The flex duct stapled across Timberwood Park’s wide, shaded attics degrades at connection points first. Collars loosen. Boots pull away from registers. We repair or replace damaged flex sections, re-secure with mechanical fasteners, and seal with mastic. Flex duct repair in Timberwood Park typically falls between $280-$450 per run, depending on length and access.
Metal Duct Repair
Older metal trunk lines in Timberwood Park’s 1980s builds corrode at seams and develop pinholes that leak air and draw attic dust into supply ducts. We patch, seal, or replace sections as needed, always photographing the condition we found. Metal duct repair here usually ranges $380-$620 per section.
Duct Insulation
Insulation on attic-run ducts in Timberwood Park compresses, tears, or gets stripped by rodents in the Hill Country canopy. We replace with properly rated insulation and vapor barrier, critical for preventing condensation that feeds mold in humid attics. Duct insulation work runs $260-$480 per system in this market.
Mastic Sealant Application
We specify mastic sealant as its own service because Timberwood Park’s climate demands it. Brush-applied mastic fills gaps that tape can’t, cures flexible, and lasts through thousands of expansion cycles. It’s the standard we apply at every joint and collar, not an upsell.
Air Leak Repair
Leak detection in Timberwood Park often reveals pressurized air escaping at the air handler cabinet, plenum connections, or poorly sealed return-air pathways. We pressure-test, locate, and repair, then verify with post-repair measurement. Air leak repair here typically adds $180-$340 to a sealing job when bundled.

We don’t claim performance beyond manufacturer specifications. What we do guarantee is that the right component gets installed correctly, photographed, and backed by our written warranty.

Common Duct Repair & Sealing Problems We See in Timberwood Park Homes
- Cedar pollen packs return ducts every winter. From December through February, mountain cedar pollen penetrates standard filtration and accumulates in return-air pathways. The fine, yellowish coating our crews pull from filters and duct interiors each January pressurizes joints and pops lightly stapled flex connections, causing supply leaks even when the house feels sealed tight.
- Summer heat cycles destroy flex duct collars. June through September, Timberwood Park’s unconditioned attics hit temperatures that expand and contract flex duct repeatedly. Mastic tape alone fails. Collars separate. Unconditioned air and outside allergens infiltrate the supply system until proper mastic sealant and mechanical fastening are applied.
- Three-system homes get underbid by square footage. Because many Timberwood Park homes rely on dual or triple all-electric heat pump systems, contractors who price by conditioned square footage often inspect only one system. Two duct runs go unaddressed, mold spores keep circulating, and the homeowner pays twice.
- Shaded attics trap moisture that feeds mold. The dense live oak and cedar canopy that keeps Timberwood Park attics cooler than average also limits airflow and traps humidity. Condensation forms on poorly insulated ducts, and mold colonizes inside runs where homeowners can’t see it until musty air starts blowing from registers.

FAQs - Duct Repair & Sealing in Timberwood Park
You won’t feel most duct leaks because they happen in unconditioned attics, pulling hot, humid air into the system or blowing conditioned air into spaces you don’t occupy. In Timberwood Park, we regularly measure 20-35% air loss at the air handler and trunk takeoffs of homes where the owners reported no drafts. The leak shows up as uneven room temperatures, short-cycling equipment, and energy bills that climb without explanation. Call (830) 549-6847 and we’ll pressure-test your system and show you the numbers in writing.
Each heat pump system in your home has its own air handler, duct runs, and set of connection points that need inspection, sealing, and documentation. We price per system because a three-system home requires roughly triple the labor, materials, and photo documentation of a single-system home. Square-footage bidding leaves systems uninspected and problems circulating. Our written quote itemizes each system separately so you know exactly what was addressed and what was found. Call (830) 549-6847 for a per-system estimate.
Every CleanRun job in Timberwood Park concludes with a Documented Photo Record: interior photos of every duct run, before and after, showing the condition we found and the work performed. You also receive the written scope, the written price agreement, and the 365-Day Done Right Promise. This is standard, not optional. Haven Standard Clause 4 requires it. If a contractor won’t put attic work in writing and on camera, you have no verification that anything happened behind the drywall.
Yes, measurably. The Ashe juniper pollen that clouds Timberwood Park air from December through February is fine enough to pass through standard 1-inch filters and accumulate in return ducts in a single season. Our crews working here in January routinely find filters and duct interiors coated with the yellowish residue. Homes sealed tight against the cold pressurize that pollen straight into the duct system, where it feeds mold, restricts airflow, and stresses blower motors. Post-cedar-season inspection is a reliable annual need in this specific community. Call (830) 549-6847 to schedule after the season peaks.
Signs visible to homeowners include rooms that won’t hold temperature, registers with weak airflow, or musty odors when the system runs. In Timberwood Park’s attics, we find the physical damage at collars, boots, and crushed sections where flex duct was poorly supported across wide spans. We photograph everything before recommending repair or replacement, and we show you the images before quoting. Flex duct with limited collar damage and intact insulation usually repairs well; duct with widespread deterioration, mold penetration, or rodent damage gets replaced. Call (830) 549-6847 for an inspection and written recommendation.
Last month we worked a two-story home off Timberwood Park Road with three heat pump systems, where the second-floor flex runs in the shaded attic had started to leak at the collars after years of June-September heat cycles. Using a Rotobrush agitation tool under negative pressure and HEPA filtration, we removed cedar pollen and organic debris from the supply and return ducts, then sealed the collars and boots with mastic and re-insulated the trunk lines. The blower motor stopped short-cycling, and the homeowner’s MERV rating filter swap finally made sense because the source removal was done first.
Because Timberwood Park’s 1980s-2000s semi-custom Hill Country homes had no natural gas lines when the subdivision was platted, many rely on dual or triple all-electric heat pump systems with attic-run flex duct, so duct sealing bids here must count multiple systems rather than sq ft of conditioned space. A contractor quoting by square footage might inspect one system and pronounce the whole house done. We inspect and document every system, every run, every time.
