Duct Sealing in Broadview Park - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Broadview Park

Homes in Broadview Park lose an average of 20 – 30% of conditioned air through leaky ductwork before it ever reaches the rooms you’re paying to cool. In a neighborhood where concrete-block ranches built between the 1950s and 1970s still dominate the streets near Peters Road and the canal crossings, those leaks add up fast. We’re Hollis Air Duct Cleaning, and our crews work these Broward County blocks regularly. We know the low-ceiling slab homes around Broadview Park, the retrofitted duct systems that got rerouted after past hurricanes, and the particular way humidity here finds every gap in aging mastic seals. If your AC runs constantly but some rooms stay stubbornly warm, or your summer electric bills keep climbing, leaky ducts are the likely culprit. Call us at (361) 326-5060 for a free estimate. We’ll put the price in writing before any work starts, and every seal we apply is covered by our 365-Day Done Right Promise.

HVAC Duct Sealing in Broadview Park

HVAC Duct Sealing in Broadview Park means closing the gaps, cracks, and separated joints in the ductwork that moves conditioned air through your home. In this neighborhood’s small mid-century ranches, we typically find leaks at the plenum connections, where flex duct meets metal trunk lines, and at registers that were cut into walls without proper collars. The job involves applying professional-grade mastic sealant and metal-backed tape rated for high-velocity systems, then pressure-testing to confirm the seal holds. Most Broadview Park homeowners need this service when rooms won’t maintain temperature, when dust blows from specific vents, or after a hurricane repair disturbed the original duct layout. A typical whole-system seal in this market runs $450 – $850 depending on accessibility and the extent of separation.

When Sealing Beats Replacement

In Broadview Park’s original low-velocity systems, the metal trunk lines are often solid but the connections have failed. Sealing those joints restores airflow without the $2,000 – $4,000 cost of full duct replacement. We use mastic from Abatement Technologies, applied thick enough to bridge gaps up to 1/4 inch and flexible enough to handle the thermal expansion these old systems see every summer.

Post-Hurricane Seal Checks

After roof work or interior repairs, we regularly find return ducts in Broadview Park homes pulling attic air through gaps the storm crew never sealed. A pressure test finds these invisible leaks fast. We seal them with mastic and mechanical fasteners, not duct tape, which degrades in our humidity within months.

Duct Repair in Broadview Park

Duct Repair in Broadview Park addresses the physical damage that sealing alone won’t fix: crushed flex duct, rusted metal trunk lines, and sections that were improperly rerouted during past renovations. The canal-crossed lots here mean many homes sit on fill soil that shifts slightly seasonally, stressing slab-mounted duct connections. We see collapsed returns in duplexes where tenants have stored items in utility closets, and rodent-damaged flex in crawl-adjacent systems near the C-11. Repair work ranges from $280 for a single section replacement to $1,200 for multiple runs with register relocation. Every repair gets a written price before we cut anything, and the 365-Day Done Right Promise covers both materials and labor.

Rusted Metal and Moldy Flex

Broadview Park’s year-round humidity rusts galvanized trunk lines from the inside out, especially where condensation pools at low points. We cut out the damaged section, splice in new metal with sealed collars, and insulate to prevent future sweating. For mold-saturated flex duct, we replace the full run, not just the visible portion.

Storm-Rerouted Systems

Hurricane repairs often left Broadview Park homes with duct runs that make no mechanical sense: sharp 90-degree bends, sagging flex that traps water, and supply lines that terminate in walls. We remap these layouts for proper airflow, then seal every new connection to code.

Trusted Brands We Service in Broadview Park

Our vans carry mastic, tape, and replacement materials from Guardsman and Abatement Technologies, plus rotary brush systems from Rotobrush for pre-seal cleaning. We don’t order parts from a warehouse three counties away. For Broadview Park customers, that means same-day completion on most sealing jobs and next-day turnaround when a custom metal fitting is needed. If your system uses Aprilaire filtration components, we check those housings for air leaks during every seal job. The connection between filter rack and return plenum is a common leak point in these older homes, and sealing it properly improves both efficiency and filtration.

Common Duct Sealing Problems We See in Broadview Park Homes

• Humidity-caked mastic failure. The original sealant in 1960s and 70s Broadview Park ranches has dried and cracked after decades of summer moisture cycling. We scrape it clean and apply new, flexible mastic rated for 200+ degrees and 100% humidity.
• Hurricane-repair debris in returns. After roof work near Peters Road or State Road 7, drywall dust and insulation fibers blow into ductwork and clog the filter, increasing pressure that blows out weak seals. We clean before we seal, every time.
• Slab-settlement separations. The fill soil under Broadview Park’s canal-adjacent lots shifts with wet seasons, stressing slab-mounted duct boots. We find the gaps with a smoke pencil and seal with mastic plus mechanical strapping.
• Retrofit register cuts without collars. Previous owners often cut supply vents into walls without proper metal collars, leaving a 1/2-inch gap that leaks into the wall cavity. We install collars and seal to the duct, not just the drywall.
