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 Pinewood
Duct sealing in Pinewood typically runs $450 – $950 for a whole-home seal on a standard single-family system, and most jobs are scheduled within a few business days after your call. We’re the Pinewood crew from Hollis Air Duct Cleaning, and we know these homes – the 1970s ranches off the lakefront, the low-rise apartment blocks near the main corridor, the modest single-family places built when flexible duct was new and stapling was standard practice. Our dispatch team answers live at (361) 326-5060, and scheduling is coordinated from our Miami office with crews that serve Pinewood locally. We don’t guess at what we’ll find; we inspect first, write the price down, then seal it right.

Duct Insulation in Pinewood
Duct Insulation in Pinewood is usually the second half of a proper sealing job, not a standalone service, because the same humid, sandy conditions that loosen your tape also saturate your flex duct jacket and compress the fiberglass wrap. When we open a chase in a Pinewood home, we regularly find the original insulation has settled to half its R-value, wet from attic condensation or past roof leaks, with the vapor barrier torn at every collar. We strip that compromised wrap, seal the underlying leaks with mastic and foil tape on dry, clean surfaces, then re-insulate with fresh fiberglass wrap and a proper vapor barrier so the conditioned air stays conditioned from the air handler to the register.
A typical Duct Insulation job in Pinewood, done as part of a full seal, adds $200 – $400 to the total. Standalone re-insulation of accessible runs runs $350 – $600 depending on linear footage and attic access.
When Insulation Fails Before the Seal
We won’t seal over wet insulation. In Pinewood’s older subdivisions, especially after a tropical system or a summer of daily afternoon thunderstorms, we pull back the jacket and find saturated wrap that would mold within a month if we sealed it in. We air-dry or replace first, then seal. That’s written into our process, not an upsell.
Re-Insulating Crushed Flex Runs
Homeowners sometimes re-tape a crushed run from the outside, thinking the fix is cosmetic. The interior flex stays pinched, airflow stays low, and the blower motor runs hot. We open the chase, restore the round profile, seal the collar properly, and re-insulate so the run performs like new.
HVAC Duct Sealing in Pinewood
HVAC Duct Sealing in Pinewood means something specific: re-taping and re-masticcing runs that were sized and stapled for open-window living in the 1970s – 1990s, then punished by decades of daily A/C cycling and year-round humidity. The original foil tape dries and curls. Stapled collars work loose. Mastic applied over wet, sandy flex duct jackets during the rainy season never bonds – the seal peels within one summer and pulls humid attic air straight back into your supply and return. We use professional-grade equipment from Rotobrush and Nikro to put the system under negative pressure, verify our seal with a pressure pan test, and leave you with a written result.
Whole-home HVAC Duct Sealing in Pinewood runs $450 – $950 for most single-family systems. Partial sealing of identified leaks, found during a cleaning or inspection, runs $180 – $450.
Pressure Pan Testing After the Seal
We don’t trust our eyes alone. After sealing, we place a pressure pan over each register and measure leakage under system pressure. If the number doesn’t meet our standard, we reopen the chase and find what we missed. You get the before and after numbers in writing.
Sealing the Air Handler Closet Boot
The boot over the air handler closet is the most common failure point we find in Pinewood homes. Original 1970s – 1980s boots were stapled, not sealed, and years of vibration work them loose until they’re effectively a hole sucking in attic air. We remove the old fasteners, seal the plenum seam with mastic, mechanical-fasten the boot, and verify with a smoke pencil.
Trusted Brands We Service in Pinewood
We carry professional-grade equipment and materials from Rotobrush, Nikro, and Abatement Technologies on every Pinewood job – the same rotary brush systems, negative-air machines, and HEPA filtration units that commercial crews use, not hardware-store gear. For filtration upgrades tied to sealing work, we stock Honeywell, Aprilaire, and Guardsman products. Having the right parts on the van means we don’t leave your job to chase a fitting across Miami-Dade County. Most Pinewood seals are completed in a single visit because we arrive prepared.
Common Duct Sealing Problems We See in Pinewood Homes
- Rainy-season seal failure: Mastic and foil tape applied over wet, sandy flex duct jackets during Pinewood’s humid summer never bonds properly. The seal peels within one season, pulling humid attic air and fine local soil straight into your ducts. We dry and prep every surface before we seal.
- Stapled collars worked loose: Original 1970s – 1980s collars and plenum seams were stapled, not sealed. Decades of daily A/C cycling in Pinewood’s near-constant cooling season vibrate them until the boot over your air handler closet is effectively an open hole.
- Crushed runs masked with surface tape: Homeowners re-tape crushed flex from the outside instead of opening the chase. The interior stays pinched, airflow stays low, and the blower motor short-cycles until it fails. We restore the round profile and seal properly.
- Humid attic air feeding microbial growth: After a summer of daily afternoon thunderstorms, we find musty odors and reduced airflow across Pinewood’s older subdivisions – not from visible dust, but from humid air and fine local soil combining inside interior flex ducts to feed mold at the vents and air handler.

FAQs About Duct Sealing in Pinewood
Because in Pinewood’s 1970s – 1990s homes, the ducts are often leaking faster than they’re dirtying. A rotary brush cleaning removes buildup, but if your stapled collars are sucking in humid attic air and fine local soil all year, the problem returns in months. Sealing stops the infiltration at the source. Call (361) 326-5060 and we’ll inspect to tell you which job you actually need.
Pinewood’s daily afternoon thunderstorms and tropical humidity mean we never seal over wet surfaces. Mastic applied to damp, sandy flex duct jackets fails within one summer. We schedule around weather patterns when possible, dry and prep every surface, and use mechanical fasteners at critical joints so the seal survives the next storm cycle.
Sealing alone won’t restore a crushed flex run. If your low airflow is from a pinched duct, we open the chase, restore the round interior profile, seal the collar properly, and re-insulate. The seal keeps it sealed; the structural repair keeps it round. Both are needed, and we price them separately in writing so you know what you’re paying for.
We clean first, then seal. In Pinewood’s moisture-driven environment, we put the system under negative pressure with Nikro equipment, run agitation tools for source removal, and capture debris with HEPA filtration. Sealing over dirty ducts traps mold food inside. Sealing clean ducts keeps them clean. Call (361) 326-5060 to schedule both.
Musty odor at the supply registers, uneven cooling between rooms, and a blower motor that runs longer than it used to are the three most common signs we see in Pinewood homes. We verify with a camera inspection and smoke pencil – the leak is usually visible where the original staples have worked loose. We’ll show you on the monitor before we quote the repair.
