Duct Sealing in Lantana - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Lantana

Duct sealing in Lantana typically runs $450 – $1,200 for a whole-home system, depending on how much of the original galvanized ductwork can be saved versus replaced. Most jobs take a half day to a full day, and we write the price down before we touch anything.

Call (361) 326-5060

We’re familiar with Lantana’s mix of mid-century concrete block homes east of US-1 and newer construction toward the west. Our crews serve Lantana from our Miami office, so we’re not driving down from West Palm or up from Fort Lauderdale. That matters when you’re trying to schedule around work or when a failed duct run has your AC running nonstop. Call us at (361) 326-5060 and we’ll set a window that we actually arrive inside.

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

Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In Lantana, that longevity means something. We’ve worked on the original 1950s and 1960s systems in neighborhoods like Hypoluxo Island, the areas near Lantana Municipal Beach, and the streets running off Pine Tree Lane. Homeowners here know that a technician who understands how salt air corrodes galvanized metal is worth more than one who brings a coupon and a roll of tape.

Our Duct Sealing team arrives uniformed and background-checked, under The Garrison Code. The price is written before work starts, and it does not move at the door. Every repair carries our 365-Day Done Right Promise: if it fails within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No waiting until Monday for a callback.

We don’t compete on the lowest teaser price. We compete on showing up when we said, pricing it before we touch it, and doing it by the book. That’s The Garrison Standard, and it’s how we operate in Lantana.

Duct Sealing Services in Lantana

Duct Sealing Services in Lantana address a problem most homeowners don’t know they have: conditioned air leaking into attics, wall cavities, and crawl spaces before it ever reaches the rooms where people live. In Lantana’s climate, that means your AC works harder to fight humidity that never should have entered the duct system in the first place. We use mastic and mesh tape on accessible joints, seal boot penetrations with proper collars, and verify our work with static pressure testing. A typical duct sealing job in Lantana runs $450 – $1,200.

Source Removal Before Sealing

We don’t seal over contamination. Before any mastic goes on, we clean accessible supply and return ducts under negative pressure with HEPA filtration, using Nikro equipment and Rotobrush rotary brush systems where appropriate. Sealing dirty ducts traps mold and debris. That’s not how we work.

Static Pressure Verification

After sealing, we test. If the static pressure at the far registers hasn’t improved, we keep looking for leaks. In Lantana’s older homes, the biggest losses are often at the plenum or boot connections, not the trunk line itself. We find them and we fix them.

Duct Insulation in Lantana

Duct Insulation in Lantana matters because uninsulated or poorly insulated ductwork in your attic turns into a condensation generator the moment humid outside air meets the cold metal of your AC system. In Lantana, where humidity stays high eight months of the year and salt air accelerates corrosion, sweating ducts are a constant threat. We install foil-faced fiberglass insulation with proper vapor barriers on accessible trunk lines and plenums, sealing all seams to prevent moisture intrusion. A typical duct insulation job in Lantana runs $600 – $1,800, depending on linear footage and accessibility.

Condensation Control

Sweating ducts don’t just waste energy. They rot ceiling drywall, breed mold, and destroy the very ductwork they’re supposed to serve. Our insulation work includes checking for existing moisture damage and recommending remediation before we cover anything up.

Tight Chase Solutions

Lantana’s newer waterfront condos often have duct runs buried in tight chases with no access panel. We evaluate what’s reachable and give you an honest assessment of what insulation work is practical versus what requires a different approach entirely.

Trusted Brands We Service in Lantana

We stock parts and materials from Aprilaire, Abatement Technologies, and Guardsman for Lantana jobs, plus we carry Rotobrush and Nikro equipment on every truck. That means when we find a failed boot or corroded plenum on a mid-century home near the Intracoastal, we’re not ordering parts and making you wait. We have the mastic, mesh tape, insulation, and antimicrobial treatments to finish the job in one visit. Fast turnaround matters in Lantana’s climate. Every day a leaking duct runs unsealed is another day your AC works overtime and your attic grows mold.

Common Duct Sealing Problems We See in Lantana Homes

• Sealing over active corrosion. Applying mastic or tape to galvanized duct that is already pitted and rusted through near the Intracoastal is a temporary fix at best. The salt air keeps working underneath, and the seal fails within a season. We assess whether the metal is sound enough to save or if replacement is the honest recommendation.
• Missing the disconnected boot and plenum leaks. In Lantana’s 1950s-1970s concrete block homes, the biggest pressure loss is often at the register boot or air handler plenum, not the trunk run itself. A sealing job that only treats visible trunk joints leaves the real problem untouched. We inspect with cameras before we quote.
• Ignoring moisture and microbial contamination before sealing. In Lantana’s salt-laden humidity, sealing ducts that still harbor mold colonies just traps the problem. The ducts need antimicrobial treatment and moisture control first, or the seal becomes a mold incubator. We treat first, then seal.
• Original unsealed plenum-and-boot assemblies. Many Lantana homes were built with galvanized trunk lines that were never mechanically sealed at the joints. Sixty-plus years of thermal cycling have opened leaks at every takeoff. Duct sealing here is frequently a rust remediation problem first and an airflow problem second.
