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.

Our Duct Repair & Sealing Services in Frisco

Duct Sealing
Frisco’s large-footprint homes - often 3,000-5,000 square feet with four or five bedrooms - rely on extensive trunk-and-branch systems where every collar and joint is a potential leak point. We seal with mastic compound and metal-backed tape rated for attic temperature swings, not the cloth-backed tape builders used that dries and peels in 140°F summer attics. A typical duct sealing job in Frisco runs $280-$480 for partial-system work and $480-$920 for full trunk-and-branch sealing on the largest homes.

Flex Duct Repair
The flex-duct branches in Frisco’s boom-era homes were stapled and taped fast during construction, often before drywall sanding finished. After 10-15 years of thermal cycling, collars pull loose and the inner liner tears at stress points. We replace failed flex runs with new R-6 or R-8 insulated duct, secure collars with draw bands and mastic, and photograph every connection. Flex duct repair in Frisco typically costs $180-$340 per run, with most homes needing 2-4 runs addressed.

Metal Duct Repair
Older metal trunk lines in some Frisco subdivisions from the early 2000s develop seam separation and corrosion at condensate collection points. We patch with galvanized sheet metal and sealant, or replace sections when the metal has thinned. Metal duct repair in Frisco runs $220-$450 depending on accessibility and extent.

Air Leak Repair
Leaks in Frisco homes often show up as rooms that won’t hold temperature despite the AC running continuously. We pressurize the system, locate leaks with smoke pencils and thermal imaging, then repair and verify with a second pressure test. Air leak repair in Frisco is typically bundled with sealing work at $280-$650 total.

Duct Insulation
When flex-duct outer insulation has compressed or moisture has degraded the vapor barrier, we re-insulate or replace to restore thermal resistance. This matters in Frisco’s attics, where 140°F summer temperatures turn uninsulated ductwork into a heat sink that works against your compressor.

Common Duct Repair & Sealing Problems We See in Frisco Homes

- Loose flex-duct collars bleeding air into attics. The tape and staples used during Frisco’s construction boom have aged past their service life in thousands of homes simultaneously. We find collars separated by 2-3 inches in attics above Preston Road and Legacy Drive, dumping cooled air into 140°F spaces while bedrooms starve.
- Drywall-dust “flour” choking supply plenums. In the Williamsburg subdivision off Preston Road, our crew camera-inspected a 2014 Highland Homes build where the original flex-duct branches had never been touched since handover - drywall-dust flour still caked the supply plenum, and two branch runs had pulled loose at the collar, bleeding conditioned air into the attic. After source removal under negative pressure with HEPA filtration, we re-sealed every collar with mastic, replaced the failed flex runs, and the homeowners’ upstairs rooms finally held temperature in August.
- Pollen loading on never-cleaned return duct walls. Hill Country cedar pollen peaks December through February, followed by heavy spring oak pollen. In Frisco’s continuously running systems, this material cakes onto return duct surfaces, loading filters prematurely and masking leaks that only show up as uneven room temperatures.
- Multi-zone system complexity hiding isolated failures. Frisco’s large homes often have three or four zones with dampers that compensate for duct problems - until they can’t. A single leaking branch can go unnoticed for years while the system overworks to compensate.

FAQs - Duct Repair & Sealing in Frisco

A 2015 Frisco home is now 10 years old, which is the window where construction-phase tape fails and flex-duct collars pull loose. The ductwork was installed while drywall dust and blown insulation were still airborne, and that debris has hardened in place while mechanical connections aged. Call (469) 452-7766 for a camera inspection and written estimate - estimates are free.
Frisco’s hypergrowth meant thousands of homes were framed, drywalled, and HVAC-roughed-in within weeks of each other. Ductwork was often pressurized for the first time while construction dust still filled the air, and without professional cleaning, that material remains. The pattern is so consistent across neighborhoods like Lexington, Williamsburg, and Hollyhock that experienced local techs treat it as a default assumption. We document it with photos every time.
Yes. In Frisco’s large homes with long flex-duct runs to second-floor zones, loose collars and torn inner liners are more common than compressor failure. The AC unit may be producing sufficient cold air; it’s just bleeding into the attic before reaching the registers. A pressure test and camera inspection will show whether the problem is the ductwork or the mechanical system. Call (469) 452-7766 and we’ll put it in writing.
North Texas receives heavy Hill Country cedar pollen December through February and spring oak pollen March through May. In continuously running systems - Frisco’s HVAC operates 8-9 months annually - this material accumulates on return duct walls and in the plenum, restricting airflow and masking leaks. The pollen itself becomes a diagnostic problem: it obscures visual inspection and can falsely indicate a clean surface while the duct behind it leaks. Source removal under negative pressure clears the obstruction and reveals the actual condition.
Proper duct repair starts with a camera inspection to locate leaks, debris, and mechanical damage. We seal accessible joints with mastic, replace failed flex runs, then verify with a pressure test. Negative-pressure extraction - pulling debris through the system toward a HEPA-filtered vacuum rather than blowing it into the living space - prevents recontamination during cleaning. This matters in Frisco homes where drywall-dust flour and pollen have accumulated for years; agitation without containment would release that material into the air you breathe. Every step is photographed before and after, and the photo record is delivered as part of your job documentation.
