Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Sealing Across Fort Myers Beach
Duct sealing in Fort Myers Beach typically runs $450 – $850 for a whole-home system, and most jobs are scheduled and completed within a single visit. We dispatch crews from our Miami (South FL) office and serve Fort Myers Beach directly, so you’re not waiting on a contractor who’s figuring out island access for the first time.
We’ve worked on elevated stilt homes from Estero Boulevard back to the canals off San Carlos Island, and we know what salt fog and Hurricane Ian’s lingering effects have done to ductwork here. The open crawlspaces beneath most Fort Myers Beach homes don’t just let cooling escape through gaps, they let humid, salt-laden air in, accelerating corrosion and forcing your AC to work harder than it should. When ducts leak, you’re paying to cool your crawlspace. Our Duct Sealing team finds those leaks, seals them with mastic and professional-grade materials, and gives you a written price before touching anything.

Why Hollis Air Duct Cleaning Is Fort Myers Beach’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our crews have handled post-hurricane ductwork on Fort Myers Beach since the months after Ian. That matters here in ways it doesn’t on the mainland. When a home on Mango Street or along the north end of the island has ducts pulling in salt air through corroded seams, the technician needs to recognize corrosion patterns that only show up in barrier-island conditions.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. When you call (361) 326-5060, you talk to someone who can schedule your Fort Myers Beach job and confirm your appointment window on the spot.
Every technician we send is background-checked, uniformed, and expected to operate under The Garrison Code: arrive inside the quoted window, price the job in writing before starting, complete the work by the book, and leave the site clean. The price we write down does not move at the door. If our seal fails within a year, we return and make it right at no charge, including a free second visit. That’s the 365-Day Done Right Promise, and it’s backed in writing on every job.

Duct Sealing Services in Fort Myers Beach
Duct Sealing Services in Fort Myers Beach address the leaks, gaps, and separated seams that let conditioned air escape and unconditioned air enter your home’s duct system. In this market, most sealing jobs focus on metal ductwork in open crawlspaces where salt corrosion has degraded factory seals, or on flex duct that has pulled loose from collars during storm events. A typical whole-home duct sealing in Fort Myers Beach runs $450 – $850 depending on system size, accessibility, and whether antimicrobial treatment is needed for mold-prone areas.
Leak Detection and Assessment
We pressurize your duct system and use smoke pencils and thermal imaging to locate every leak, not just the obvious ones. In Fort Myers Beach homes, we regularly find that the worst leaks are at plenum connections and where flex duct passes through unconditioned attic or crawlspace areas, spots that standard visual inspections miss entirely.

Mastic Sealing and Reinforcement
We seal leaks with water-based duct mastic, a thick compound that remains flexible and won’t crack like tape does under thermal expansion. For corroded metal seams, we apply reinforcing mesh embedded in mastic, creating a permanent seal that withstands the humidity cycling unique to this climate.

Duct Insulation in Fort Myers Beach
Duct Insulation in Fort Myers Beach prevents the condensation that forms when cool air moves through ducts in hot, humid crawlspaces and attics. In elevated homes from the south end near Big Carlos Pass to older construction off Estero Island, uninsulated or degraded duct wrap is a major source of energy waste and moisture problems. A typical duct insulation job in Fort Myers Beach runs $600 – $1,200 for a whole system, depending on linear footage and whether existing insulation must be removed due to mold or flood damage.
Vapor-Barrier Insulation Replacement
We install foil-faced fiberglass wrap with a proper vapor barrier, sealed at all seams to prevent humid exterior air from reaching the duct surface. In Fort Myers Beach’s climate, standard insulation without a complete vapor seal often becomes a moisture trap, promoting mold growth on the duct exterior that eventually penetrates inward.
Rigid Duct Board Upgrades
For severely corroded metal duct runs, we sometimes recommend replacing sections with insulated duct board, which provides both structural integrity and thermal protection in one unit. This is particularly effective in pier-and-beam homes where salt air has pitted the original metalwork beyond reliable repair.
Trusted Brands We Service in Fort Myers Beach
Our equipment roster includes Nikro negative-air machines, Honeywell filtration components, and Aprilaire humidity control products, the same tools commercial crews use on larger installations across Lee County. We stock sealing mastics, reinforced tapes, and insulation materials sized for residential ductwork common to Fort Myers Beach’s housing stock, which means most jobs don’t wait on parts. When a homeowner on San Carlos Island or near Times Square calls with a system that’s leaking cooled air into a crawlspace, we arrive with what we need to complete the seal in one visit. For specialized applications, we source from Abatement Technologies, whose containment and filtration products meet the standards we apply under The Garrison Standard.
Common Duct Sealing Problems We See in Fort Myers Beach Homes
- Corroded metal seams from salt fog exposure. The open crawlspaces beneath elevated homes on Fort Myers Beach let salt-laden air circulate around ductwork year-round. We regularly find pinhole leaks and separated seams on galvanized metal that would last decades inland but fails prematurely here.
- Flex duct pulled loose by pest activity or storm surge. Raccoons and rodents seeking shelter in crawlspaces after storms often dislodge flex duct from collars. After Hurricane Ian, we found this problem repeatedly in homes near the back bay where water drove animals into normally dry spaces.
- Plenum leaks at the air handler. The sheet metal box connecting your AC to the duct system often develops gaps at corners and access panels, especially in homes built before 1990 with original equipment. These leaks are invisible from below but can waste 20% or more of your conditioned air.
- Mold-damaged tape and failed DIY repairs. Homeowners sometimes try sealing leaks with hardware-store foil tape that degrades in months under Fort Myers Beach humidity. We remove these temporary fixes and apply mastic rated for wet-location permanence.
