Our Duct Repair & Sealing Services in Timberwood Park

Duct Sealing

Timberwood Park’s homes lose conditioned air through gaps at plenum connections, register boots, and seams in metal trunk lines - the plenum being the central distribution box where your air handler meets the duct system. We seal with mastic sealant, a fiber-reinforced compound that remains flexible after curing, unlike tape that dries and fails. In homes near the dry creek beds off Timberwood Park Road, we’ve measured leakage rates above 30% of total airflow - air you’re paying to cool that never reaches a register. Our sealing work includes pre- and post-seal pressure testing, and the results go in your photo record.

Flex Duct Repair

Original flex duct in Timberwood Park’s 1970s-2000s builds has degraded from decades of continuous operation and attic heat. The flexible plastic-and-wire tubing crimps behind walls, gets crushed by storage, or tears at connections. Our crew was called to a two-story home off the Evans Road corridor where the homeowner reported that both systems were short-cycling and that the main living area never felt balanced. Using camera inspection, we found original flex duct in the attic had been crimped and torn by squirrels at two duct boots and a return chase; after source removal and HEPA filtration, we repaired the runs with mastic sealant and Guardsman flex duct, then verified static pressure drop had improved across all supply and return ducts. We don’t guess. We photograph, measure, and document.

Metal Duct Repair

Some Timberwood Park homes, particularly the larger custom builds, use galvanized steel trunk lines with flex duct branches. Metal ducts rust at seams, separate at joints, or vibrate loose from hangers. We repair with proper sheet-metal techniques - not duct tape - and re-insulate where attic heat gain has degraded the original wrapping. Every repair is photographed before and after, with the location noted by room and duct run number.

Duct Insulation

Attic temperatures in Timberwood Park exceed 140°F in July. Uninsulated or degraded duct insulation wastes cooling capacity before air reaches your registers. We install foil-faced fiberglass insulation at R-6 or R-8, depending on the application, sealed with mastic at all seams. The work is photographed and the insulation type recorded in your job documentation.

Mastic Sealant Application

Mastic is our standard for all Timberwood Park sealing work - not tape, not aerosol, not shortcuts. We brush-apply a 1/16-inch minimum thickness at all joints, connections, and penetrations. The material we use is rated for the temperature swings these attics see. It’s slower than tape. It lasts longer. We photograph every sealed joint.

Air Leak Repair

Leak detection in Timberwood Park requires more than a smoke pencil. We use camera inspection and static pressure measurement to locate leaks hidden behind drywall or in attic chases. Rodent entry at duct boots and attic penetrations tears flex duct and creates hidden air leaks that standard pressurization tests won’t pinpoint without camera inspection. Once located, leaks are repaired with appropriate materials and re-tested. The before-and-after pressure readings go in your written record.

Common Duct Repair & Sealing Problems We See in Timberwood Park Homes

• Crushed or crimped original flex duct in complex two-story layouts. Timberwood Park’s larger homes often have duct runs that snake through finished walls and attic chases. Over decades, these get compressed by storage, construction, or their own weight. The restriction makes the air handler work harder and run hotter than designed. Camera inspection finds what a register airflow test cannot.
• Cedar pollen and caliche dust coating return-side duct interiors. The Edwards Plateau climate subjects these homes to extreme summer cooling loads, and the limestone-derived caliche dust on unpaved shoulders throughout the neighborhood is ultrafine and abrasive. When leaks are sealed without first doing source removal, that residue gets pulled deeper into the system. We clean before we seal - always.
• Rodent and ringtail cat damage at duct boots and attic entries. The wooded, semi-rural character of Timberwood Park lots means squirrels, birds, and ringtail cats common to the Hill Country find their way into attics. They tear flex duct and create leaks that pressurization tests alone won’t locate. Camera inspection is standard on every Timberwood Park job for this reason.
• Multiple systems with unbalanced airflow. Many Timberwood Park homes have two or three separate AC systems. When one system’s ductwork is compromised, the others compensate - or the homeowner over-cools the whole house trying to get one room comfortable. Per-system pricing lets you address the worst offender first without committing to the entire house.
