We’ve been in Davie homes long enough to know the real issue isn’t dust. It’s decades-old fiberboard and flex duct that have been through repeated hurricane outages, humidity cycles, and the slow delamination that happens when AC sits off for three days and condensation breeds inside the plenum. Our Duct Sealing team treats this as moisture remediation, not a surface clean.

Why Hollis Air Duct Cleaning Is Davie’s Preferred Duct Sealing Company

Hollis Air Duct Cleaning, part of the Garrison Partners family since 2004, handles Davie calls under The Garrison Standard: written price, written guarantee, and a 365-Day Done Right Promise that covers every sealing job in writing. If the work fails within a year, we come back at no charge. That includes a free second visit, not a negotiation.

Our technicians are background-checked and uniformed. You know who’s walking in before they arrive. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for a scheduling window.

We know Davie’s housing stock. The 1970s – 1990s ranches off Orange Drive and Griffin Road, the CBS block construction, the sprawling equestrian properties with detached barns and guest houses that share the main air handler but were never properly sealed. That local knowledge changes what we look for in a camera inspection and what we quote before we touch anything.

Duct Insulation in Davie

Duct Insulation in Davie is usually the missing piece after sealing, because original 1970s – 90s ranch homes were built with uninsulated or poorly insulated fiberboard runs that sweat in the attic during our humid summers and lose conditioned air before it ever reaches the register. A typical duct insulation job in Davie runs $600 – $1,400 depending on linear footage, attic accessibility, and whether we’re replacing water-damaged wraps or adding new R-8 insulation to previously bare flex runs.

Attic Sweat and Condensation Control

Davie’s year-round humidity means uninsulated metal or bare flex duct in a 140-degree attic drips condensation onto ceiling drywall. We install proper R-8 duct insulation with vapor barrier, sealed at every seam, so the cold air stays cold and the attic heat stays out.

Post-Hurricane Insulation Replacement

After Hurricane Irma and subsequent outages, we replaced saturated duct insulation in dozens of western Davie homes where the old wrap had become a mold substrate. New insulation after proper sealing prevents the next cycle. We use professional-grade materials from Abatement Technologies and Guardsman, not hardware-store wrap.

HVAC Duct Sealing in Davie

HVAC Duct Sealing in Davie addresses the leaks, gaps, and disconnected runs that pull humid outdoor air into your system and push conditioned air into unconditioned spaces. A typical whole-home HVAC duct sealing job in Davie runs $450 – $1,200, with smaller partial-system repairs starting around $280. Price depends on system size, attic accessibility, and whether we’re sealing accessible joints or chasing leaks behind drywall.

Mastic and Mesh for Lasting Seals

We seal with duct mastic and reinforcing mesh, not tape that dries and fails. Mastic stays flexible, fills irregular gaps, and holds through Davie’s thermal expansion cycles. Every joint gets inspected with a camera before we close up, so we know the seal held under pressure.

Pressure Testing After Sealing

We run a post-seal pressure test to measure duct leakage reduction. Davie homes with original fiberboard often start at 25 – 35% leakage. We target under 10%. You get the before-and-after numbers in writing, same as the price.

Trusted Brands We Service in Davie

Our crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration and sealing products from Honeywell, Aprilaire, and Guardsman. For Davie customers, that means no waiting on parts shipped from Orlando or Miami warehouses. If your system needs a specific collar, boot, or mastic compound to match an older installation, we typically have it on the van. The same tools commercial crews use, applied to your ranch home off Griffin Road or your equestrian property near Orange Drive. Fast turnaround because we’re not ordering as we go.

Common Duct Sealing Problems We See in Davie Homes

• Delaminated fiberboard after moisture cycles. The original duct board in 1970s – 80s Davie ranches separates at the seams after repeated hurricane outages let humid air condense inside. Sealing over damaged substrate hides the problem until the next storm. We camera-inspect first, replace what’s failed, then seal what’s sound.
• Crushed flex runs in hot attics. Western Davie neighborhoods have flex duct that sags and kinks under summer heat loads, especially where original strapping failed. Mastic at the register boot doesn’t fix a crushed run that’s passing zero air. We re-strap or replace, then seal.
• Disconnected barn and guest house ducts. Equestrian properties along Griffin Road often share the main home’s air handler with detached structures that were never sealed or insulated. Air escapes into unconditioned space, and the house pulls humid outdoor air through every gap. We seal and insulate the secondary runs, or recommend independent systems if the load doesn’t match.
• Boot-to-plenum gaps from thermal cycling. Davie’s daily afternoon thunderstorms and temperature swings expand and contract metal connections. Gaps open at the air handler plenum that tape can’t hold. We use mastic and mesh, mechanically fastened, for a seal that moves without breaking.
