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.

AfterFast, Reliable Duct Sealing Across Town ‘n’ Country
We seal ducts in Town ‘n’ Country homes where the combination of gulf humidity, slab-on-grade construction, and 130°F attics destroys standard sealing jobs. A typical duct sealing project here runs $450 – $1,200 depending on system size and whether we’re addressing wet insulation or just joint leakage. Call (361) 326-5060 for a written estimate before any work starts.
Our crews know the difference between a quick register seal and the real problem: bay and gulf moisture pushing attic dew points above the temperature of your cool supply ducts. That’s why our Duct Sealing team starts with a camera inspection and moisture check, not a sales pitch. Dispatch and scheduling are coordinated from our Miami office, but the technicians who arrive at your door serve Town ‘n’ Country regularly and understand the local housing stock, from the mid-century ranches near West Hillsborough Avenue to the two-story stucco homes off Sheldon Road.
Why Hollis Air Duct Cleaning Is Town ‘n’ Country’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our reputation in Town ‘n’ Country is built on showing up inside the quoted window, pricing in writing, and leaving the site clean.

The 365-Day Done Right Promise covers every duct sealing job in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit.

We serve Town ‘n’ Country with the same professional-grade equipment commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We explain what each tool does and why it matters for your specific system.
Duct Insulation in Town ‘n’ Country
Duct Insulation in Town ‘n’ Country is often the missing half of a sealing job. The subtropical humidity here, amplified by proximity to both Tampa Bay and the Gulf of Mexico, routinely pushes attic dew points above the temperature of cool supply ducts. Without proper insulation, condensation soaks flex duct and surrounding insulation, destroying any seal you just paid for. A typical duct insulation project in Town ‘n’ Country runs $600 – $1,800 depending on linear footage and whether we’re replacing water-damaged material.
When Insulation Becomes Part of Sealing
We find wet insulation behind apparently sound duct tape on most older homes here. The seal looks fine until the mastic peels away from the saturated surface underneath. Our protocol: dry or replace the insulation, then seal. Doing it in reverse is why so many Town ‘n’ Country homeowners call us a year after another company’s “seal” failed.
Attic vs. Crawlspace Applications
Homes off Sheldon Road with 130°F attics need different insulation than slab-on-grade properties where ducts run through damp wall cavities. We match the R-value and vapor barrier to the location, not just the duct size. In crawlspaces prone to tropical-system flooding, we use closed-cell insulation that won’t absorb standing water.
HVAC Duct Sealing in Town ‘n’ Country
HVAC Duct Sealing in Town ‘n’ Country addresses the specific failure modes this climate creates: condensation-driven sealant peeling, sagging flex duct at low spots, and negative pressure pulling damp crawlspace air back into returns. A typical sealing job for a standard single-family system runs $450 – $950; if we need to address wet insulation or replace damaged flex sections, expect $800 – $1,200. We write the price down before touching anything.
The Condensation-First Protocol
Because Town ‘n’ Country sits unincorporated between Tampa Bay and the Gulf, its subtropical humidity routinely pushes attic dew points above the temperature of cool supply ducts. Sealing must address the condensation plane before it soaks the flex duct and insulation. This is worse here than in inland suburbs because bay and gulf moisture plus slab-on-grade construction keeps crawlspaces and wall cavities wetter. We check moisture content with a meter before applying mastic. If it’s wet, we dry it or replace it. Sealing over moisture is sealing over a time bomb.
Joint-by-Joint vs. Aeroseal Methods
For the older ranch and two-story homes with original flex duct from the 1970s – 80s building boom, we typically use manual mastic-and-mesh sealing at accessible joints plus targeted replacement of damaged sections. Aeroseal has its place for hard-to-reach leaks in intact metal ductwork, but it doesn’t address the sagging, water-damaged flex we commonly find here. We recommend the right method for your actual system, not the one with the best marketing.
Trusted Brands We Service in Town ‘n’ Country
We stock parts and materials from Rotobrush, Nikro, and Guardsman for fast turnaround on Town ‘n’ Country Dryer Vent Cleaning and duct sealing jobs.

For filtration upgrades after sealing, we carry Honeywell and Aprilaire products sized to your system. Having the right material on the van means we don’t leave your job half-finished waiting for a parts run. That’s part of The Garrison Standard: complete the job by the book, leave the site clean.
Common Duct Sealing Problems We See in Town ‘n’ Country Homes
- Sealing over wet surfaces. In Town ‘n’ Country’s slab-on-grade homes, hidden condensation from gulf humidity causes sealant to peel and mold to return within months. We moisture-test every surface before applying mastic.
- Register-only sealing while attic flex duct sags. The real leakage is at the low spots and disconnected collars in 130°F attics, not the register faceplates. Surface-level work misses where your conditioned air is actually escaping.
- Treating duct seal as a crawlspace moisture cure. Without addressing flooded crawlspace insulation after tropical-system rain, negative pressure pulls damp air back into supply and return ducts. The seal holds; the problem persists.
- Ignoring 1970s flex duct degradation. Original flex from the building boom has reached end of life. It sags, it tears at collars, and the inner liner delaminates. Sealing joints on failing flex is polishing a rusted bumper.

FAQs About Duct Sealing in Town ‘n’ Country
Every 5 – 7 years for homes with metal ductwork in dry attics, but every 3 – 5 years for properties with original flex duct or moisture-prone crawlspaces. The constant A/C use May – October plus gulf humidity accelerates sealant degradation here compared to drier inland markets. Call (361) 326-5060 and we’ll inspect to give you a specific interval for your system.
June – September humidity pushes moisture into attic and crawlspace ductwork where previous roof leaks or poor ventilation have left insulation damp. The musty smell is mold growing on wet duct surfaces and debris. Sealing alone won’t fix it; we need to dry or replace the wet material first, then seal. That’s why our camera inspection includes moisture mapping.
Sealing reduces the dust that enters through leaks in your return ducts, but it doesn’t stop dust at windows, doors, or on shoes. For homes near unpaved roads, we typically pair duct sealing with a MERV 11 or higher filter upgrade to catch what sealing misses. The real win is stopping your return system from pulling dusty attic or crawlspace air into your living space.
Replacement, usually. Original flex duct from the 1970s – 80s building boom has exceeded its design life. The inner liner cracks, the insulation compresses, and the sagging creates pools of condensation that no sealant can fix. We can seal accessible joints as a short-term measure, but we won’t sell you a seal job that ignores failing duct material. We’ll show you the camera footage and price both options in writing.
MERV 11 for most homes, MERV 13 if you have allergy sensitivity and a system designed for the airflow restriction. Higher isn’t always better; a MERV 16 filter on an undersized blower strains the motor and can cause the very leaks we just sealed. We check your system’s static pressure before recommending a filter upgrade. Call (361) 326-5060 for an exact specification.
