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.

Why Hollis Air Duct Cleaning Is Country Walk’s Preferred Duct Sealing Company
We’ve worked in Country Walk long enough to recognize the neighborhood’s builder-era duct templates on sight. The late-1980s and 1990s flex runs in these attics follow predictable patterns, which means our technicians spend less time diagnosing and more time fixing. Roy Castellanos built Hollis on The Garrison Standard – written prices, written guarantees, and a 365-Day Done Right Promise backed in writing on every job. Our crews arrive uniformed, background-checked, and inside the quoted window. Phones are answered by a live person 24 hours a day, seven days a week. When you’re deciding whether storm-damaged ducts can be sealed or must be replaced, that accountability matters.
Duct Sealing Services in Country Walk
Duct Sealing Services in Country Walk address a specific problem: conditioned air escaping through disconnected collars, deteriorated mastic, and crushed flex runs before it reaches your living spaces. We typically find this in homes off Country Walk Drive and throughout the community’s two-story stock, where original 1990s ductwork has spent three decades in attic heat exceeding 140 degrees. A full duct sealing in Country Walk runs $850 – $1,800 depending on system size, accessibility, and whether we’re reconnecting popped collars or resealing the entire trunk line. We write the price down before touching anything.
Collar Reconnection and Mastic Sealing
Most Country Walk calls start with a cleaning request but end with reconnection work. Heat cycling pops flexible duct collars off galvanized trunks; we reseat them with fiberglass mesh and UL-181 mastic, then verify static pressure at the air handler so the joint holds under August demand.
Post-Storm Damage Assessment
After water intrusion, sealing a soaked duct run wastes your money and voids coverage. We camera-inspect, take moisture readings, and document everything. If sealing is viable, we prove it. If replacement is required, we prove that too – before your insurer gets involved.

Duct Insulation in Country Walk
Duct Insulation in Country Walk is usually needed where the original jacket has collapsed or where condensation on cold supply runs has saturated the wrap. South Florida humidity means attic ductwork sits in perpetual moisture; bare or degraded insulation costs you efficiency and invites microbial growth. Replacing duct insulation in Country Walk typically runs $600 – $1,400 for a full system, with partial runs starting around $250. We use professional-grade materials from Abatement Technologies and Guardsman, not hardware-store wraps that degrade in two seasons.
Vapor Barrier Replacement
Collapsed insulation jackets expose the vapor barrier to attic heat and moisture. We strip the damaged wrap, treat any affected metal or flex, and install new insulation with sealed seams – the only method that passes muster in a 140-degree Country Walk attic.
Condensation Control
Cold air plus humid attic equals water on the duct surface. We address the root cause: proper insulation R-value, sealed joints, and verified airflow that keeps surface temperature above the dew point. Sealing over wet insulation traps moisture and fails within one rainy season.
Trusted Brands We Service in Country Walk
Our trucks carry Rotobrush rotary systems for mechanical agitation, Nikro negative-air machines for containment, and sealing and insulation products from Abatement Technologies and Guardsman. We stock these parts locally so Country Walk jobs don’t wait on Miami warehouse runs. When your 1990s system needs a collar resealed or a saturated run rewrapped, we have the material on hand and the written price ready before the ladder goes up.
Common Duct Sealing Problems We See in Country Walk Homes
- Heat-cycled collar separation. Decades of attic expansion and contraction pop flexible duct off the main trunk. The gap looks small but bleeds 20 – 30 percent of conditioned air into the attic. We find this on nearly every two-story home built in the 1990s.
- Crushed flex runs from attic traffic. Original ductwork routed over ceiling joists gets compressed by HVAC techs, rat activity, or stored holiday decorations. Crushed duct increases static pressure and reduces airflow to the far registers.
- Condensation-saturated insulation. South Florida humidity hits cold supply lines and soaks the wrap. The duct looks intact from below but the insulation is a mold vector. Sealing without replacing the wrap traps the moisture.
- Post-storm water intrusion. After heavy rain or roof damage, homeowners want a quick seal. We camera-document first. Sealing wet ductwork fails within months and insurers reject claims where moisture was present before the seal.

FAQs About Duct Sealing in Country Walk
They can be sealed only if the duct is structurally intact and moisture readings confirm dry conditions. We camera-inspect the full run, take pinless moisture meter readings at multiple points, and document everything with dated photos. If moisture exceeds 16 percent in the flex or insulation, we recommend replacement – and our documentation supports your insurance claim. Call (361) 326-5060 for a post-storm assessment.
The original builder-grade flex duct is now 25 – 35 years old and the collars have popped loose from heat cycling. Cleaning a disconnected duct just agitates debris in the attic; sealing restores airflow first. We see this pattern consistently in Country Walk’s two-story stock. Call (361) 326-5060 to check your collars before scheduling cleaning.
Yes. The HOA architectural review governs where outdoor condensers and air handlers sit and how they’re screened, which limits access routes and noise windows for our equipment. We coordinate with homeowners to schedule during approved hours and use the quietest access path. This planning prevents mid-job stops that other crews hit unprepared.
We provide dated camera footage, moisture meter readings with model and calibration date, and a written technician report stating the duct condition and the work performed. On a two-story home off Country Walk Drive, our documentation of collar reconnection, mastic application, and post-repair static pressure testing satisfied the homeowner’s insurer without requiring full replacement. We deliver the same documentation on every job.
Rotobrush rotary systems for mechanical prep, Nikro negative-air machines for containment during disturbance, and UL-181 matic with fiberglass mesh for the seal itself. We verify with a manometer before handoff. The tools are professional-grade; the explanation is plain English. Call (361) 326-5060 to see the process on your system.
On a two-story home off Country Walk Drive, our tech camera-inspected the attic and found the original 1990s flexible duct sitting in 140-degree attic heat with three supply collars pulled loose from the main trunk and the insulation jacket collapsed – the homeowner had called us for cleaning but the system was losing conditioned air before it ever reached the registers. We ran NADCA-standard negative pressure with HEPA filtration, re-sealed the collars with mastic and mesh, wrapped the runs in new duct insulation, and verified static pressure at the air handler before handoff. The homeowner’s insurer accepted our before-and-after camera documentation and the moisture readings to cover the repair.
Country Walk’s late-1980s/1990s builder-grade flex duct in attics is old enough that a large share of duct-sealing calls here are really reconnection jobs – heat-cycle sagging has popped collars off plenums before dirt ever became the issue. Because the HOA architectural review governs where outdoor condensers and air handlers sit and how they’re screened, we also have to schedule sealing work around access and noise windows that don’t exist in older unincorporated neighborhoods. This is the reality of working in a master-planned community with three decades of aging infrastructure.
