We’ve been driving our trucks to North Andrews Gardens since 1984. Ray Castillo built this company on the idea that a homeowner should know the full price before a single tool comes out of the van, and that standard still drives every job we do in the 33334 ZIP code. North Andrews Gardens is different from the cities that surround it. It’s unincorporated Broward County, a pocket of 1950s-1970s concrete block ranch homes that never saw the renovation waves that swept through Oakland Park and Wilton Manors. That matters because the ductwork in these houses has been running under near-constant AC load and coastal humidity for fifty years or more. We know what fails here because we’ve opened thousands of these systems.

Our Duct Repair & Sealing Services in North Andrews Gardens
Duct Sealing with Mastic Sealant
In North Andrews Gardens, duct sealing isn’t about chasing a few leaks. The salt-laden air coming off the Intracoastal Waterway, less than two miles away, infiltrates aging seams year-round. We seal metal duct joints and connections with professional-grade mastic sealant, not tape that will peel in the attic heat. Mastic remains flexible, fills irregular gaps, and creates a permanent bond that stops conditioned air from escaping into your hot, humid attic. For homes near Commercial Boulevard or NE 56th Street, where we’ve found some of the worst corrosion patterns, proper mastic sealing can recover 20-30% of lost cooling efficiency.

Flex Duct Repair
Flex duct in North Andrews Gardens fails differently than it does inland. The outer plastic jacket tears from decades of attic heat and critter traffic, then humid attic air condenses on the inner liner. We see this constantly in the unrenovated ranches between NW 31st Avenue and Powerline Road. Our flex duct repair replaces damaged sections with new, properly sized flex runs, supports them so they don’t sag or kink, and seals the connections with mastic and mechanical fasteners. We recently repaired ductwork in a 1960s CBS ranch on NW 22nd Street where the original flex duct had corroded at metal collars due to salt air from the Intracoastal. We replaced sections with Rotobrush-cleaned metal duct, sealed all joints with mastic, and insulated new flex runs to prevent future moisture intrusion.

Metal Duct Repair
When metal duct collars and registers corrode from North Andrews Gardens’s persistent 75-90% relative humidity, we don’t patch and pray. We cut out corroded sections, fabricate replacements from galvanized steel, and coat new installations for added protection against salt-air degradation. Metal duct repair is often the right choice for the main trunk lines in these older homes, where the original galvanized steel has held up better than the fiberglass duct board it connects to.

Duct Insulation
Uninsulated or degraded duct insulation is a major efficiency loss in North Andrews Gardens. Attic temperatures in these low-pitch CBS ranch roofs regularly exceed 130°F in summer. Without proper insulation, your cold air warms up before it reaches the vent. We install new fiberglass duct wrap or replace insulated flex runs with properly R-rated material, sealed at every penetration. This matters especially for homeowners near the Intracoastal, where the humidity differential between attic and duct is at its most extreme.

Common Duct Repair & Sealing Problems We See in North Andrews Gardens Homes
- Delaminated fiberglass duct board shedding shards into living spaces. In unincorporated North Andrews Gardens, original fiberglass duct board from the 1950s-1970s is still common, and coastal salt air has often delaminated the interior lining, sending loose shards and biofilm directly into living spaces. This isn’t a rare find here. It’s a neighborhood-wide pattern.
- Corroded metal collars and registers from salt-laden Intracoastal air. The persistent high humidity and salt content in the air accelerates corrosion of metal duct components far faster than even inland Broward locations. We regularly replace collars that have turned to flaky rust.
- Aging flex duct with torn outer jackets allowing attic moisture intrusion. The 1950s-1970s ranch homes throughout North Andrews Gardens still run original or early-generation flex duct. The outer vapor barrier degrades, humid attic air contacts the inner liner, and mold colonizes the cavity. By the time the homeowner smells it, the damage is extensive.
- Disconnected duct runs in inaccessible attic spaces. Low-pitch CBS ranch roofs don’t leave much room to work. Duct connections in these tight attics often separate from vibration, thermal expansion, and the weight of accumulated dust and moisture. We find fully detached runs blowing thousands of BTUs into the attic every hour.

FAQs - Duct Repair & Sealing in North Andrews Gardens
Fiberglass duct board was the standard material for residential ductwork in the 1950s through 1970s, when nearly all of North Andrews Gardens’s housing stock was built. Because this unincorporated pocket saw far less gut-renovation than neighboring Oakland Park or Wilton Manors, a disproportionate number of homes still run original duct board systems that have now aged 50+ years in subtropical conditions. If your home was built before 1980 and hasn’t had a full HVAC overhaul, you likely have duct board somewhere in the system. Call (844) 685-6342 and we’ll camera-inspect to confirm.
North Andrews Gardens’s position less than two miles from the Intracoastal Waterway means persistent relative humidity of 75-90% and salt-laden air that infiltrates duct seams year-round. This moisture condenses on cooler duct surfaces, promotes mold colonization, and accelerates corrosion of metal components far faster than in inland Broward County locations. The salt content is the critical difference. It corrodes metal collars and registers that might last decades elsewhere. Call (844) 685-6342 for a free inspection of your ductwork’s moisture damage.
No. Once fiberglass duct board has delaminated and is harboring mold or biofilm, sealing the exterior joints does not address the contamination inside the duct. The damaged sections must be removed and replaced. We use mastic sealant on the new connections and proper insulation to prevent future moisture intrusion, but there is no repair that salvages mold-saturated duct board. If you’re seeing dust that looks like loose insulation or smelling mustiness from your vents, call (844) 685-6342 for a camera inspection and honest assessment.
In North Andrews Gardens, metal collars and registers fail first due to salt-air corrosion, followed by flex duct outer jackets tearing from heat and age, then fiberglass duct board delaminating from decades of moisture cycling. The supply plenum connections at the air handler are also high-failure points because temperature differentials are greatest there. We inspect these critical points first on every job. Call (844) 685-6342 to schedule a system evaluation.
Rarely, and we don’t recommend it for this climate. Modern North Andrews Gardens installations typically use sheet metal trunk lines with insulated flex duct runs, or fully fabricated sheet metal systems. Duct board has been largely replaced by better materials, though some low-bid contractors still use it. If you’re getting estimates for duct replacement, ask specifically what material is being installed. We use metal and properly insulated flex, and we’ll show you exactly what we’re proposing before work begins. Call (844) 685-6342 for a written estimate with material specifications.
If your North Andrews Gardens home is running original ductwork from the 1960s or 1970s, you’re not imagining the dust, the musty smell, or the rooms that never cool properly. We’ve opened enough systems in the 33334 ZIP code to know what you’re dealing with. We’ll camera-inspect your ductwork, show you what we find, and give you one honest price to fix it. No bait coupons. No surprises on the bill. And if it’s not done right, we’ll make it right. That’s the 90-Day Done Right Promise, and we’ve stood behind it since 1984.
