We’ve worked in Lighthouse Point long enough to know the real enemy here isn’t dust, it’s humidity. The salt-laden air off the Intracoastal Waterway, the concrete-block ranches built in the 1960s and 70s with flex duct tucked into soffits, and the seasonal homes that sit closed for months – all of it creates a specific pattern of duct failure we see nowhere else in Broward County. Our crews are dispatched from our Miami office and serve Lighthouse Point directly. We know the difference between a home on Lighthouse Drive that’s been shut since May and a year-round place on NE 24th Street that runs AC twelve months straight. That difference matters for how we approach the job, what we find, and what we quote.

Duct Repair in Lighthouse Point

Duct Repair in Lighthouse Point usually means addressing the original flexible duct runs installed in 1960s – 1970s ranch homes, now sagging in soffits and attics after decades of salt-air exposure and condensation cycles. The repair involves locating tears, separated joints, and crushed sections, then restoring integrity with proper materials and methods. In Lighthouse Point, we see this need most often in seasonal homes where ductwork has been idle in humid conditions, accelerating material fatigue. Typical duct repair here runs $350 – $900, depending on linear feet and accessibility.

When Repair Beats Replacement

Not every compromised duct needs tearing out. If the flex runs are intact but sagging, we can re-support and seal. If collars are corroded from salt air, we replace the metal and seal the joint. We use a camera inspection to know which path before we quote – no guessing, no upsell.

What Salt Air Does to Metal Components

Lighthouse Point’s proximity to the Intracoastal accelerates corrosion of registers, boots, and collars. We see rusted-through connections in homes half the age of inland equivalents. Our repair protocol includes corrosion-resistant replacements where standard hardware would fail again within two seasons.

Air Duct Sealing in Lighthouse Point

Air Duct Sealing in Lighthouse Point is the critical follow-through after cleaning and repair – or the standalone fix when ducts are dirty but structurally sound. The job involves sealing every joint, boot, and penetration with mastic or foil-backed tape rated for HVAC use, then pressure-testing to confirm. In this market, sealing is especially important because humid outside air pulled through leaks condenses inside ducts, feeding microbial growth. Whole-home air duct sealing in Lighthouse Point typically costs $450 – $1,200.

Mastic vs. Tape – What We Use and Why

We seal with Guardsman mastic on most Lighthouse Point jobs. It remains flexible, handles the thermal expansion from near-constant AC operation, and won’t degrade in the humid attic and soffit environments common here. Duct tape, despite the name, fails in these conditions; we don’t use it.

Pressure Testing After Sealing

After sealing, we run a static pressure test to verify the system holds. In Lighthouse Point’s older homes with original duct layouts, we often find improvement of 15 – 25% in airflow efficiency. We show you the before-and-after numbers on the paperwork.

The tools are professional-grade, the same ones commercial crews use on larger facilities, and we explain what each piece does for your specific system while we work.

Common Duct Sealing Problems We See in Lighthouse Point Homes

• Sagging flex runs in soffits that never fully drain. In the ranch homes near Lighthouse Drive and NE 24th Street, original flexible duct sags at low points where condensation pools. Sealing the joints without addressing the sag just traps moisture. We re-support the run, then seal.
• Corroded collars and boots from salt-laden Intracoastal air. Metal components in Lighthouse Point homes fail faster than inland equivalents. A register that looks fine from the living room may be rusted through at the duct connection. We inspect with a camera before quoting.
• Encapsulated tears in original ductwork. Some crews skip the camera, find a tear, and seal over it with mastic. The duct looks sealed but leaks at the tear, and the mastic hides the problem. We locate tears first, repair or replace, then seal.
• Fogging “sanitizers” sold as a substitute for source removal. This is common in seasonal-home markets. The fog masks odor temporarily but does not remove settled microbial growth. In Lighthouse Point’s humid, closed-home conditions, the mold returns within a season. We remove the source, then seal to prevent recurrence.
