Our Duct Repair & Sealing Services in Highland Village
Flex Duct Repair
Flex duct repair is our most common call in Highland Village, and for good reason. The city’s 1985-2005 housing stock was built with long flex-duct runs through unconditioned attics, and after 25-40 years, those inner duct liners delaminate while the insulation compresses and loses R-value. The lake-side moisture accelerates this breakdown. We replace damaged flex sections, reconnect separated joints with proper mechanical fasteners, and verify airflow with camera inspection. A typical flex duct repair in Highland Village runs $220-$480.

Duct Sealing
Duct sealing stops the conditioned air you’re paying for from leaking into your attic. In Highland Village homes, we find the worst leaks at flex-duct connections to plenums and trunk lines - exactly where thermal expansion and the lake-area humidity have worked the joints loose over decades. We use professional-grade mastic sealant, not tape that will fail in another season. Sealing a typical Highland Village system costs $180-$350, and the energy savings usually pay back within two Texas summers.

Metal Duct Repair
Some Highland Village homes, particularly the larger custom builds from the late 1990s and early 2000s, have galvanized steel trunk lines with flex-duct branches. Where those metal ducts corrode at seams or where supports have sagged, we repair or replace sections and seal with high-temperature mastic. Metal duct repair in Highland Village typically ranges from $280-$520 depending on accessibility and extent of damage.

Duct Insulation
Duct insulation replacement is critical in Highland Village because of what happens in those attics. North Texas attic temperatures exceed 140°F in summer, and when you combine that heat with Lake Lewisville’s elevated humidity, the original insulation on your flex ducts breaks down faster than in inland suburbs. We install new insulation with proper vapor barriers, sized for the R-value your system was designed to maintain. Duct insulation work in Highland Village generally runs $340-$650 for a complete system.

Common Duct Repair & Sealing Problems We See in Highland Village Homes
- Flex duct joints separate prematurely. The combination of Lake Lewisville’s moisture-laden onshore breeze and 140°F attic temperatures creates expansion and contraction cycles that pull flex-duct connections apart faster than in inland suburbs like Corinth. We see this most often in homes within a mile of the shoreline.
- Original insulation compresses and loses R-value. Highland Village’s unconditioned attics, especially in the older subdivisions near the lake, subject duct insulation to decades of heat cycling and humidity. Compressed insulation can’t maintain temperature, so your HVAC works harder for longer.
- Debris and microbial growth accumulate faster than inland. The lake breeze acts as a continuous pump of organic particulates into exterior HVAC intakes. Technicians working lakefront subdivisions consistently find heavier biological growth inside registers compared to homes even a mile inland. Cleaning frequency for these homes should be every 2-3 years, not the typical 5-year cycle.
- Inner duct liners delaminate and shed particles. In Highland Village’s 20-40-year-old flex-duct systems, the adhesive bonding the inner liner to the wire helix degrades from moisture exposure. Homeowners notice black debris blowing from vents - that’s degraded liner material, and it means replacement is needed.
Pricing for Duct Repair & Sealing in Highland Village, TX
We’re transparent about pricing because we’ve seen what bait-and-switch looks like, and we don’t operate that way. Here’s what duct repair and sealing costs in the Highland Village market:
| Service | Typical Range in Highland Village |

| Air leak repair (multiple points) | $260-$420 |
Factors that affect your specific cost: accessibility of ductwork in the attic, extent of moisture damage, whether original 1990s-era materials need complete replacement versus spot repair, and whether your system has multiple zones requiring additional sealing points. We disclose the full price before we start - the number on the phone is the number on the invoice. Ask about our $50 off any repair over $250, or our $89 Seasonal Tune-Up if you want to catch problems before they require major repair.
We Also Serve Cities Near Highland Village
Our technicians regularly work in Flower Mound, Lewisville, Lake Dallas, and Corinth - but Highland Village’s lakeside microclimate produces duct problems distinct from all of them. The humidity differential matters. A repair strategy that works in Flower Mound’s interior sections may fail in Highland Village within two seasons. That’s why local experience counts.

FAQs - Duct Repair & Sealing in Highland Village
Every 2-3 years for inspection and maintenance, with sealing repairs addressed as soon as leaks are detected. The lake breeze continuously pulls higher-humidity, organics-laden air into your system, accelerating wear compared to inland homes on a 5-year cycle. Call (866) 347-2063 to schedule - estimates are free, and we’ll show you camera footage of exactly what your ducts look like.
Flexible ductwork with fiberglass insulation and wire-helix construction, run through unconditioned attics in long spans to serve multi-zone systems. These were standard for semi-custom and custom homes of that era, and they’re now at the age where inner liners delaminate and insulation compresses. We repair these systems daily in Highland Village.
Partial repair is often possible if the wire helix is intact and damage is localized to joints or short sections. Complete replacement becomes necessary when inner liners are extensively delaminated or when multiple repair points would exceed the cost of new duct runs. We recently repaired a multi-zone system in the Lakeside Estates neighborhood near Lake Lewisville, where the lake breeze had caused heavy biological growth and delamination of inner duct liners. After sealing leaking flex joints with mastic and replacing degraded insulation, the homeowner saw a 30% drop in humidity inside the home. We’ll give you an honest assessment - call (866) 347-2063 for a free second opinion on any written estimate.
Yes - it’s especially worth it here because unsealed ducts pull attic humidity directly into your living space, compounding the lake-area moisture problem. Proper mastic sealing blocks that infiltration and reduces the load on your dehumidification. Most Highland Village homeowners see improved comfort and measurable energy savings within the first billing cycle. We back every sealing job with our 90-Day Done Right Promise.
Highland Village’s position on Lake Lewisville creates a consistent onshore breeze that pumps organic particulates into exterior HVAC intakes - a factor Flower Mound’s interior sections simply don’t experience. Technicians working lakefront subdivisions nearest the water consistently find heavier biological growth and denser debris inside registers compared to homes even a mile inland. More frequent cleaning and proactive sealing are the right response, not a more powerful filter that restricts airflow. Call (866) 347-2063 and we’ll explain what your specific system needs.
