Fast, Reliable Duct Sealing Across Ojus
Duct sealing in Ojus runs between $450 and $1,200 per system for most homes, depending on how many leaks we find and whether the chase access is tight. We know the homes here: 1950s and 1960s ranches off West Dixie Highway, newer rebuilds near Keystone Point, and a lot of ductwork hidden in flat-roof chases where nobody can see it failing. Our crews seal ducts by the book, document everything with camera footage, and leave a written price before we touch anything. If you’re losing cool air through dried-out joints or pinhole corrosion, call (754) 354-3644 for a straight answer and a free estimate.

Why Hollis Air Duct Fort Lauderdale Is Ojus’s Preferred Duct Sealing Company
We are not the cheapest bid in Ojus, and we won’t pretend otherwise. We are the crew that shows up inside the quoted window, walks the property, and hands you a written price before the first tool comes off the truck. Our techs are background-checked and uniformed, and they work under The Garrison Code: arrive on time, price in writing, do the job the right way, leave the site clean. Roy Castellanos leads our team with a simple rule: if the work fails within a year, we return at no charge.
Ojus homeowners call us after another company left them guessing. Our Duct Sealing crews have handled everything from single-trunk ranch systems to three-zone luxury builds where hidden chases mean we need camera snakes just to find the runs. We answer the phone 24/7 with a live person. You’ll get a real answer, not a voicemail loop.
Dispatch and scheduling are coordinated from our Miami (South FL) office, and crews serve Ojus locally. That means the technician who seals your ducts knows the difference between a 1960s flat-roof chase near the Intracoastal and a new construction attic with accessible decking. That local knowledge changes how long the job takes and what it costs.
Styles & brands we work with




Duct Insulation in Ojus
Duct insulation in Ojus matters because uninsulated metal ducts in hot or humid chases sweat, and that moisture feeds mold and degrades the duct exterior over time. The job involves wrapping or replacing insulation around supply and return runs, sealing seams in the insulation jacket, and verifying the system holds temperature through long runs between the air handler and far registers. Homeowners in Ojus typically need this when they notice condensation dripping from a chase, when rooms at the end of a long run blow warm, or after a renovation exposes old fiberglass wrap that’s torn or water-stained.
Expect to pay $300 to $700 per system for duct insulation replacement in Ojus, depending on run length and how much old material needs removal. A three-system home with long trunk lines can push toward the top of that range or slightly beyond. We quote it in writing before work starts, and the number doesn’t move at the door.
When Insulation Is the Real Problem
Sometimes homeowners call us for sealing and discover insulation is the actual culprit. Sweating ducts in a humid Ojus chase create the same musty smell and uneven cooling as an air leak, but mastic won’t fix it. We identify this with a temperature probe before recommending any work.
What Insulation Replacement Covers
The job includes removing deteriorated wrap, checking the duct exterior for corrosion while it’s exposed, installing new R-6 or R-8 rated insulation, and sealing every seam in the jacket. You get before-and-after photos so you can see what was under the old wrap, even when you can’t climb into the chase yourself.
HVAC Duct Sealing in Ojus
HVAC duct sealing in Ojus means locating and sealing every leak across an entire system: joints, takeoffs, trunk lines, plenum connections, and chase penetrations. We do this with commercial-grade mastic and aluminum tape applied to code, not quick-fix foil tape. Homeowners in Ojus need this when energy bills climb without a change in usage, when rooms run warm despite a newer AC, or when humidity inside the house spikes even with the system running. On a three-system home, that means testing and sealing each system separately, because one sealed system does nothing for the other two.
Whole-system HVAC duct sealing in Ojus runs $450 to $1,200 per system. Seal-only work on a single ranch system with good access lands near $450 to $650. A three-zone luxury home with hidden chases and multiple pinhole leaks in trunk lines can hit $900 to $1,200 per system. We use HEPA-filtered negative pressure testing to verify airflow after the seal, so you get numbers showing what changed.
Sealing Hidden Chases
Most Ojus mid-century homes have duct runs routed through flat-roof or low-slope chases with no access panels. We use flexible camera snakes to map the runs, locate leaks, and apply mastic at the problem points without tearing out ceilings. That’s the difference between a sealed system and a guess.

Three-System Pricing Logic
Large Ojus homes often have separate systems for different zones. Per-system pricing matters because each system has its own trunk, its own takeoffs, and its own leak profile. We quote each system on its own merits, and you approve the full written price before we start any of it.
Trusted Brands We Service in Ojus
We work on duct systems tied to Honeywell zoning controls, Aprilaire filtration, and Abatement Technologies components, plus equipment from other major manufacturers. Our techs carry mastic, tape, insulation wrap, and common replacement parts on the truck, so most Ojus jobs finish in a single visit. If we find a specialized damper or plenum fitting that needs replacement, we can usually source it from local supply houses the same day. You’ll know the exact part and price before we order anything.

AfterCommon Duct Sealing Problems We See in Ojus Homes
- Dried and separated joints in original mid-century ductwork. The mastic and tape used 50 to 60 years ago break down from heat and humidity. Leaks at joints go unnoticed until energy bills climb or a room never cools, because the chases hide everything.
- Pinhole corrosion from salty coastal air near Biscayne Bay. Metal ducts exposed to that air develop small holes over years. Sealing only the joints on a three-system home leaves the trunk lines leaking, so we inspect the full metal surface, not just connections.
- Improper transitions after a renovation. Contractors sometimes leave old duct sections in place and connect new ones with mismatched transitions. The junction points leak, and only a camera inspection shows the gap before you pay for another round of sealing.
- Sweating ducts in flat-roof chases. Ojus’s subtropical humidity means uninsulated or poorly sealed ducts in low-slope chases condense. The moisture drips into ceilings, feeds mold, and corrodes the exterior. Sealing plus insulation replacement is often the only real fix.
Pricing for Duct Sealing in Ojus, FL
Here are the real numbers for Ojus. Basic whole-system sealing on a single-system ranch: $450 to $650. A two-system home with accessible attic or chase runs: $800 to $1,400 total. A three-zone luxury home with flat-roof chases and camera work: $1,500 to $3,000 total. Each price is quoted per system, in writing, before work begins. The biggest variable in Ojus is access: hidden chases add camera time and careful mastic work, which is honest labor that takes longer than an open attic. When we quote you a number, it’s the number you pay. Call (754) 354-3644 for a free estimate and a written price that will not change when the technician arrives.

FAQs About Duct Sealing in Ojus
You’ll notice three things: rooms that never reach the thermostat setting, humidity inside the house that rises even when the AC runs, and energy bills that climb without a change in usage. We confirm leaks with a camera snake through the chase and a negative pressure test that measures system leakage. Call (754) 354-3644 to schedule an inspection, and we’ll show you exactly what the camera sees.
Yes. Each system has its own trunk line, takeoffs, and leak points. Sealing one system does nothing for the other two, and a home with three systems typically has three different leak profiles. We test and quote each system individually, so you only pay for what each one actually needs. Call (754) 354-3644 for a per-system written quote.
Yes, and we see it regularly in Ojus homes near Biscayne Bay. Salt-laden air settles on metal duct exteriors, and over years it creates pinholes that leak air no mastic-at-the-joint job will catch. Our inspection includes the full metal surface, not just connections. If you’re near the water and have never had the trunk lines camera-inspected, call (754) 354-3644.
You should expect before-and-after camera footage of every sealed point, a written summary of the work performed, the airflow numbers from the post-seal pressure test, and the year-long coverage terms of our 365-Day Done Right Promise. We hand this to you at the end of the job. If a leak recurs within that year, we return and fix it at no charge. Call (754) 354-3644 for the details in writing.
Often yes. Renovation dust settles inside the duct system, and contractors frequently leave old and new duct sections connected with improper transitions that leak at the junction. Even if the ducts were never disconnected, the dust and junction gaps are worth inspecting. Call (754) 354-3644 and we’ll camera-inspect the runs before you pay for sealing. If the transitions are sound and the system tests tight, we’ll tell you that straight.
We sealed the ducts on a 1960s ranch near Keystone Point where three separate supply runs ran through inaccessible ceiling chases. Using our Rotobrush camera snake, we located multiple pinhole leaks at the takeoffs and sealed them with mastic, then verified airflow at each register with a HEPA-filtered negative pressure test. The homeowner now gets even cooling across all three zones without the musty smell that used to come from the attic chase. That’s the standard we bring to every Ojus job.
