We know Brandon’s housing stock because we work here regularly. Our crews dispatch from the Miami office and serve neighborhoods from Bloomingdale to Providence Lakes, so we’re familiar with the concrete-block subdivisions built from the 1980s through the 2000s and the newer construction going up near Lithia Pinecrest. That local knowledge matters because a 1995 home in Lakewood Ridge has different duct problems than a 2022 build, and we price accordingly.

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

Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our Duct Sealing in Brandon work follows The Garrison Standard: arrive inside the quoted window, price in writing before touching anything, finish by the book, leave the site clean. Brandon homeowners aren’t looking for the cheapest bid. They’re looking for the bid that doesn’t change once the van is in the driveway.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Every duct sealing job carries our 365-Day Done Right Promise in writing: if the seal fails or the leak returns 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 callback queues.

We’ve earned a strong local reputation in Brandon because we treat the cause, not the symptom. A homeowner calls saying their ducts need cleaning because dust shoots out after every thunderstorm outage. Often the real problem is a plenum collar that was never properly sealed, or flex duct that has sagged and split in the attic heat. We tell you what we find, show you the camera footage, and write the price down before we open our mastic bucket.

Duct Sealing Services in Brandon

Duct Sealing Services in Brandon address the leaks, gaps, and separated joints that let conditioned air escape into your attic and let attic air get pulled into your living space. In Brandon’s market, a typical whole-house duct sealing job runs $350 – $850 for a single HVAC system, with larger homes or dual-system setups running higher. We use duct sealing mastic, metal-backed tape, and mechanical fasteners where appropriate, not the gray tape that dries and falls off in a hot attic.

Leak Detection and Sealing

We pressurize your duct system and use smoke pencils or thermal imaging to find every leak, including the ones hidden above your insulation. In Brandon’s 140°F attics, we often find flex duct that has pulled away from the collar, or trunk lines where the original tape has turned to dust. We seal with mastic, which stays flexible and bonds to metal, fiberglass, and flex duct surfaces.

Plenum and Boot Restoration

The plenum, where your air handler connects to the duct trunk, and the register boots, where ducts meet your ceiling or wall vents, are the most common failure points in older Brandon homes. We remove old tape and degraded sealant, clean the mating surfaces, and re-seal with proper materials so the joint holds through Florida’s heat and humidity cycles.

Duct Insulation in Brandon

Duct Insulation in Brandon wraps and protects your sealed ductwork from the attic heat that works against your air conditioner every minute it runs. In Brandon’s humid subtropical climate, uninsulated or poorly insulated ducts in a 140°F attic can raise your supply air temperature by 10 – 15 degrees before it reaches your vents. A typical duct insulation job in Brandon runs $400 – $950 depending on linear footage, accessibility, and whether we’re insulating rigid metal trunk lines or wrapping flex duct.

Vapor-Barrier Wrapping

We use insulation with an intact vapor barrier, sealed at the seams, to prevent condensation from forming on cold duct surfaces in Brandon’s high humidity. Condensation inside duct insulation breeds mold and degrades the wrap from the inside out. Our crews check every wrap joint and tape it closed so moisture stays outside where it belongs.

Rigid Duct Board and Replacement

Some Brandon homes from the 1980s and 1990s still have uninsulated metal duct or degraded duct board that has crumbled at the corners. Where the existing material is too far gone to seal and wrap, we replace sections with new insulated duct board or flex duct, sealed and wrapped to current standards. We write the scope and price before we cut anything.

Trusted Brands We Service in Brandon

Our Duct Sealing crews carry professional-grade equipment and materials from Nikro, Honeywell, and Aprilaire. We stock mastic, metal-backed tapes, and insulation wraps locally so we’re not waiting on a parts run while your attic is open. For filtration upgrades after sealing, we source Honeywell and Aprilaire media cabinets and Guardsman treatments where sanitizing is warranted. The tools are the same ones commercial crews use on schools and medical buildings. We just bring them to your home in Brandon and explain what each one does before we start.

Common Duct Sealing Problems We See in Brandon Homes

• Builder-grade flex in 140°F attics sags and splits at the collar. Homeowners in Brandon’s 1980s – 2000s subdivisions often seal the outside of a visible tear while the leak stays inside the duct, blowing attic insulation and dust into bedrooms every time the system cycles.
• New-build homeowners treat handover dust as normal. Drywall debris in the return of a Bloomingdale or Providence Lakes new build keeps shedding into the blower motor until source removal and a negative pressure pass happens, but the permanent fix is sealing the return plenum and filter rack that the builder left gaping.
• Post-storm restart puffs get blamed on “dirty ducts.” After every Brandon afternoon thunderstorm outage, the HVAC restart pulls a puff of dust and attic debris through supply vents. The real fix is sealing the plenum and register boots that storms and attic heat have loosened, not just scheduling another cleaning.
• Upstairs rooms that never cool evenly. In Brandon’s concrete-block, single-story homes with shingle roofs, the duct run to the master bedroom is often the longest and leakiest. Sealing the trunk joints and adding insulation where missing usually fixes the temperature split without touching the AC unit.
