Duct Sealing in Hickory Creek - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Hickory Creek

If your utility bills keep climbing and rooms near Lewisville Lake never match the thermostat, your ductwork is likely leaking conditioned air into the attic. In Hickory Creek, most homes built during the 1990s and 2000s still run on original flexible ductwork that’s never been sealed since installation, and the combination of hot attic temperatures, cedar pollen infiltration, and lake humidity makes those leaks worse every season. We’re the Duct Sealing crew that serves Hickory Creek from our Dallas-Fort Worth dispatch office, and we typically book sealing jobs within a few days, not weeks.

Duct Repair in Hickory Creek

Duct Repair in Hickory Creek usually means fixing sections of flexible ductwork that have sagged, torn, or pulled loose from plenums in the intense attic heat that builds above two-story brick homes in The Shores and Hickory Creek Estates. We see this most often in systems installed during the 1990s – 2000s construction boom, where builders routed cheap flex duct through unconditioned spaces that regularly hit 140°F in July and August. A typical duct repair in Hickory Creek runs $280 – $520 depending on accessibility and how many sections need replacement versus spot sealing.

When Repair Beats Replacement

Localized damage from a single rodent entry point, a disconnected collar near the air handler, or a crushed section where a storage box sat in the attic, these are repair situations. We cut out the damaged span, install a proper splice with mechanical fasteners and mastic, and test static pressure before we leave.

Full Section Replacement

When flexible duct has degraded across its entire length, the inner liner is delaminating, or fiberglass insulation is saturated with condensation from lake humidity, we replace the run. We use R-8 insulated flex or switch to rigid metal where the application calls for it, sealed with Abatement Technologies products rated for antimicrobial resistance.

Air Duct Sealing in Hickory Creek

Air Duct Sealing in Hickory Creek addresses the slow, invisible loss of conditioned air through gaps at plenum connections, seams between trunk sections, and penetrations where duct passes through unconditioned attic space. In this market, we regularly find 15 – 30% air loss in homes that have never been sealed since original construction, which means your compressor runs longer, your upstairs bedrooms stay hot, and your electric bill reflects every minute of waste. A whole-system duct sealing job in Hickory Creek typically costs $1,200 – $2,400 for an average 2,000-square-foot home with attic-distributed ductwork.

Mastic Sealing Versus Tape

We use duct sealing mastic, a thick, fiber-reinforced compound that brushes onto seams and cures into a permanent flexible seal. Foil tape fails in Hickory Creek attics within two to four years from heat cycling; mastic lasts the life of the system when applied correctly.

Pressure Testing After Sealing

Every sealing job ends with a static pressure test and a visual inspection of accessible runs. We show you the before-and-after readings, explain what changed, and document the work for your records. No guesswork, no “trust us, it’s better.”

Common Duct Sealing Problems We See in Hickory Creek Homes

• Original flex duct sagging in hot attics. Homes in Hickory Creek Estates and The Shores were built with flexible ductwork strung through trusses that weren’t designed for the weight of accumulated dust and lake humidity. Over twenty years, the duct sags between supports, creating low spots where condensation pools and airspeed drops to nearly zero.
• Plenum separations from heat cycling. The temperature swing between a 140°F August attic and a 55°F winter morning causes metal plenums to expand and contract at different rates than the duct attached to them. The connection loosens, mastic cracks, and conditioned air pours into the attic instead of the living space.
• Rodent damage in wooded lakefront lots. Hickory Creek’s heavy tree cover and proximity to Lewisville Lake means squirrels and roof rats access attics regularly. They chew flex duct for nesting material, leaving gaps that pull in unfiltered outdoor air, cedar pollen, and musty lake humidity.
• Builder-grade collars never properly sealed. During the 1990s – 2000s construction rush, many Hickory Creek homes got duct systems where installers relied on friction fit or a single zip tie at takeoff collars. No mastic, no sealant, just raw leakage that gets worse as the house settles.
