Our Duct Repair & Sealing Services in Naples Manor
Flex Duct Repair
This is our most frequent call in Naples Manor, and for specific reasons. In the 1960s-through-1980s CBS homes that dominate this community, original flex duct was routed through unconditioned attics that hit 150°F regularly from May through October. Decades of heat cycling soften the wire helix inside flex duct, especially at 90-degree elbows where airflow changes direction and stress concentrates. We’ve replaced collapsed flex sections on homes along Santa Barbara Boulevard where the elbow had sagged into a U-shape, trapping condensate wicked in from the Everglades moisture corridor.
Our repair protocol: cut out the damaged section, inspect the upstream and downstream runs for secondary sag points, replace with properly supported flex or transition to insulated metal at high-stress bends, then pressure-test before we leave.
Mastic Sealant Application
Mastic is the only sealing method we trust for Naples Manor’s attic conditions, but it has to be applied correctly. The original mastic in these older homes has dried and cracked from thermal cycling — we’ve peeled off brittle, flaking sealant that hasn’t bonded in years. We apply fresh mastic in 1/8-inch thickness at all joints and collar connections, then let it cure with the attic ventilation running. In Naples Manor’s extreme attic heat, thin or rushed mastic applications fail within two seasons. We don’t use tape as a primary seal — it delaminates.
Metal Duct Repair
Some Naples Manor homes have galvanized steel trunk lines with spot-welded seams that have rusted through from decades of condensate exposure. We patch small breaches with metal-backed mastic patches, replace severely corroded sections with snap-lock duct, and seal all transitions. Metal duct doesn’t sag like flex, but in this humidity, unsealed seams become intake points for attic air that’s 85% relative humidity in July.
Duct Sealing & Leak Repair
Our full-system sealing service starts with a visual inspection and smoke-pencil test to identify supply-side leaks that waste cooled air and return-side leaks that pull contaminated attic air into your breathing space. In Naples Manor’s market, a typical whole-system sealing runs $350–$550 for a single-story CBS home with accessible attic ductwork. We seal every accessible joint, register boot, and plenum connection, then verify with pressure differential testing.
Duct Insulation Replacement
When flex duct outer insulation has degraded from attic heat and rodent activity — common in Naples Manor’s mature tree canopy — we replace with R-8 insulated flex or wrapped metal. The insulation barrier is critical here: without it, the temperature differential between 55°F supply air and 150°F attic air creates massive condensation on duct surfaces.

Trusted Brands We Service in Naples Manor
We carry Aprilaire UV germicidal lights and media air cleaners for installation during duct repair visits — if we’ve just sealed your system and replaced a mold-contaminated flex section, adding a UV light downstream kills spores before they colonize new ductwork. Our Rotobrush contact-vacuum systems and Nikro HEPA-rated extractors clean debris from duct runs before we seal them; sealing dirty ducts just traps contamination. For containment during mold remediation work, we deploy Abatement Technologies portable air scrubbers. These aren’t entry-level residential tools — they’re the same units commercial contractors use in Naples medical and hospitality facilities. We stock replacement components for Naples Manor customers so we’re not ordering parts while your house sits at 82°F.
Common Duct Repair & Sealing Problems We See in Naples Manor Homes
- Flex duct elbows collapse from decades of attic heat cycling, creating low spots where condensate pools and mold concentrates. This isn’t gradual soiling — it’s a structural failure specific to the wire-helix construction used in 1970s and 1980s installations, accelerated by Naples Manor’s unconditioned attic temperatures.
- Original mastic sealant dries out and cracks in the hot attic, causing supply-side leaks that waste conditioned air and draw in humid attic air. We regularly find 15–20% system airflow loss from failed seals alone — your AC works harder while delivering less comfort.
- Homeowners skip post-repair pressure testing, leaving gaps that allow Everglades moisture to infiltrate the duct system and trigger rapid mold regrowth. We pressure-test every sealed system before we leave; skipping this step in Naples Manor’s humidity is asking for a callback.
- Insulation degradation exposes duct surfaces to extreme attic heat, causing supply air to warm before it reaches vents and creating condensation that drips onto ceiling drywall. We’ve replaced water-stained ceiling sections where homeowners assumed they had a roof leak.

|---|---|
| Spot mastic sealing (accessible joints, single zone) | $180–$280 |

Two-story homes, encapsulated attics, or ductwork in soffit chases may run higher. We don’t quote over the phone for replacement work without seeing the access and damage — but we don’t charge to look. Estimates are free, and Brian will show you exactly what’s failing before you decide. Call (833) 345-6820.

FAQs — Duct Repair & Sealing in Naples Manor
The wire helix inside vintage flex duct softens after years of thermal cycling in 150°F attics, and the 90-degree elbow is the highest-stress point in the run. In Naples Manor’s climate, that softening combines with humidity-degraded liner adhesive to create permanent sag. Call (833) 345-6820 and Brian will inspect your elbows with a borescope — estimates are free.
Quality mastic performs well if applied at proper thickness and allowed to cure, but thin or rushed applications fail within two seasons of Naples Manor’s thermal cycling. We apply 1/8-inch minimum thickness and verify adhesion before closing access. For a sealing assessment in 34112, call (833) 345-6820.
Yes, significantly — metal duct at high-stress elbows eliminates the sag point where condensate pools, and it withstands attic heat without structural deformation. We typically transition to insulated metal at collapsed elbows while keeping flex on straight runs for vibration isolation. Call (833) 345-6820 to discuss whether metal transition makes sense for your system.
Minor sealing and like-for-like flex replacement generally don’t require permitting in unincorporated Collier County, but modifications to trunk lines, changes to system capacity, or new duct runs may. We advise on permit requirements during our estimate and can coordinate with Collier County Building Division if needed. Call (833) 345-6820 for guidance specific to your project.
We recommend visual inspection of accessible ductwork every three years in Naples Manor, or sooner if you notice uneven cooling, musty odors, or rising electric bills. The combination of year-round AC operation and extreme attic heat degrades seals faster than seasonal-use climates. Schedule an inspection at (833) 345-6820 — estimates are free.
