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.

AfterFast, Reliable Duct Sealing Across Naranja
Duct sealing in Naranja typically runs $450 – $850 for a whole-home system, with most jobs completed in a single scheduled visit. If you’re living near the C-102 Canal or the nursery fields off SW 264th Street, you already know your ducts deal with a dark, damp organic sludge that suburban Miami systems never see. Hollis Air Duct Cleaning dispatches crews from our Miami office to serve Naranja directly, and we carry the equipment to handle farmworker-era housing that other companies underestimate. Call us at (361) 326-5060 for a free written estimate before any work begins.
Why Hollis Air Duct Cleaning Is Naranja’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team knows Naranja’s housing stock from the ground up. The concrete-block and wood-frame homes built between the 1950s and 1970s, many originally constructed for seasonal farm labor, have ductwork challenges that don’t appear in newer suburban construction. Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive inside the quoted window, price the job in writing before touching anything, complete the work by the book, and leave the site clean.
Every repair we perform in Naranja is backed by our 365-Day Done Right Promise. If the work fails within a full year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround. Phones are answered by a live person 24 hours a day, 7 days a week, so Naranja residents aren’t stuck in voicemail loops when they need to schedule or follow up.
Duct Repair in Naranja
Duct Repair in Naranja means fixing the physical damage that humidity, organic debris, and age inflict on systems never designed for this climate. We replace collapsed flex duct, repair disconnected plenum joints, and restore airflow in homes where the original 1950s – 1970s air handlers are still running. A typical duct repair in Naranja runs $280 – $550 depending on accessibility and the extent of damage.
Collapsed Flex Duct in Attics and Crawlspaces
Naranja’s uninsulated attic flex duct sags and collapses where humidity weakens the wire helix. We replace the damaged section with properly supported duct, seal with Honeywell mastic and mesh, and verify airflow at the register before we leave.
Plenum and Trunk Line Separation
The connection between your air handler and the main trunk line works loose over decades of vibration and thermal cycling. We reseat the plenum, apply fresh mastic, and mechanically secure the joint so it holds through Naranja’s wet season.
Air Duct Sealing in Naranja
Air Duct Sealing in Naranja addresses the leaks that pull unfiltered air from attics, crawlspaces, and the surrounding agricultural land into your living space. We use a combination of visual inspection, camera verification, and pressure testing to locate every leak, then seal with professional-grade mastic and reinforced tape. A whole-home air duct sealing job in Naranja typically costs $450 – $850, with partial system sealing starting around $280.
Leak Detection Before Sealing
We pressurize the duct system and use smoke pencils or theatrical fog to pinpoint exactly where air escapes. In Naranja homes near the C-102 Canal, we often find the worst leaks at unsealed register boots and at the plenum, where damp organic sludge has degraded the original sealant.
Mastic Application on Older Systems
Foil tape alone fails in Naranja’s humidity. We apply Honeywell mastic, a water-based sealant that remains flexible when cured, reinforced with mesh at stress points. On original flex duct, we verify the jacket integrity before sealing; if the duct itself is deteriorating, we tell you straight and price replacement separately.
Trusted Brands We Service in Naranja
Hollis technicians carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus sealing and filtration products from Honeywell and Aprilaire. For Naranja homeowners, this means we don’t order parts from a warehouse across the state and make you wait. Our Miami office stocks the mastic, mesh, flex duct, and register boots common to South Florida’s older housing stock, so most Naranja jobs are completed on the scheduled day without return trips for materials.
Common Duct Sealing Problems We See in Naranja Homes
- Mastic failure on damp flex duct. Naranja’s year-round humidity keeps attic duct jackets perpetually damp. The dark organic sludge from nursery fields off SW 264th Street pulls sealant away from the duct surface within a single wet season, reopening leaks you thought were fixed.
- Missed plenum leaks without camera inspection. Sealing only the accessible trunk lines while ignoring the plenum and crawlspace joints leaves the actual entry points for soil dust and pollen wide open. We camera-inspect every Naranja job near the C-102 Canal to find what visual checks miss.
- High static pressure in original air handlers. Farmworker-era homes often have 1950s – 1970s air handlers with blower motors not designed for modern MERV filters. Sealing ducts without checking static pressure can starve airflow, overheat the heat exchanger, and make the system worse instead of better.
- Reaccumulation within one growing season. Unlike suburban Miami where ducts might stay clean for two to three years, Naranja’s May – October growing season reloads organic debris so fast that sealing without source removal is temporary at best.
Pricing for Duct Sealing in Naranja, FL
Whole-home duct sealing in Naranja runs $450 – $850 for a typical single-family residence, with partial system sealing starting at $280. Duct repair, when needed before sealing, adds $280 – $550 depending on material and labor. What moves the price: the linear footage of ductwork, accessibility (crawlspace versus attic), whether camera inspection reveals hidden damage, and if source removal is required before sealing can be effective.
We give every Naranja homeowner a written price before any work starts. That price does not move at the door. No per-vent add-ons, no “while we’re here” upsells. We also provide before-and-after photos of your own ducts so you can verify the work was done. Call (361) 326-5060 for a free estimate.

FAQs About Duct Sealing in Naranja
Homes within a half-mile of the C-102 Canal and the nursery fields off SW 264th Street typically need inspection and touch-up sealing annually, with full re-sealing every two to three years. The damp organic sludge reaccumulates within a single growing season and degrades mastic faster than dry dust would. Call (361) 326-5060 to schedule an inspection and we’ll give you a written assessment of your system’s current condition.
The surrounding agricultural fields and canals generate a unique mix of soil particulates, pollen, and mold spores that standard HVAC filters don’t fully capture. Combined with Naranja’s near-constant humidity, this material forms a dark, damp sludge rather than the dry lint found in suburban Miami ductwork. Call (361) 326-5060 if you’re seeing dark buildup on your filters or registers.
Sealing alone does not eliminate existing mold, but it stops the unfiltered humid air from entering through leaks and feeding new growth. We typically recommend source removal to NADCA standards with negative pressure and HEPA filtration before sealing, especially in homes with original 1950s – 1970s systems. Call (361) 326-5060 and we’ll camera-inspect to determine whether your system needs cleaning, sealing, or both.
We use Rotobrush agitation tools for source removal when needed, then apply Honeywell mastic and mesh with mechanical reinforcement at stress points. For homes with deteriorated flex duct, we carry replacement duct and proper support straps so we’re not sealing duct that should be replaced. Call (361) 326-5060 for specifics on your system.
It can, if sealing is done without checking static pressure and blower capacity. Original farmworker-era air handlers often lack the power to push air through tightly sealed modern ductwork with higher-MERV filters. We measure static pressure before and after sealing, and we’ll tell you if your system needs airflow adjustments before we proceed. Call (361) 326-5060 for an honest assessment.
We recently sealed a 1968 concrete-block home on SW 264th Street near the C-102 Canal whose air handler was sweating onto original flex duct; a camera inspection showed a damp organic sludge lining the branch runs and we found the sludge was pulling apart the old mastic at the plenum. After source removal to NADCA standards with negative pressure and HEPA filtration, we used Rotobrush agitation tools and Honeywell mastic and mesh to seal the trunk, then resealed the registers. The homeowner reported the musty smell was gone and their filter was no longer loading dark within a month.
