Fast, Reliable Duct Repair & Sealing Across Fort Myers Shores
Duct repair and sealing in Fort Myers Shores typically costs $180–$650 depending on whether you’re sealing accessible joints or replacing flood-damaged flex duct, and most jobs are completed same-day. If your home was built between the 1960s and 1980s and still runs original ductwork, you’re likely losing 20–30% of your conditioned air through gaps and degraded insulation—plus pulling humid, possibly contaminated air back into your living space.
We’re based right here in Fort Myers, and Fort Myers Shores is a regular stop for us. Brian Rivera, our owner and lead technician, has been driving the Orange River corridor for 17 years, handling duct systems in the modest ranch homes and manufactured housing that dominate this community. We know the 33905 ZIP well—the persistent humidity off the wetlands, the older housing stock, and the specific problems Hurricane Ian left behind. When you call (833) 345-6820, you’re talking to the person who’ll actually show up with the tools and make the repair himself. Our Duct Repair & Sealing team doesn’t subcontract, doesn’t upsell, and doesn’t leave until the airflow is right.
Why Keystone Air Duct Cleaning Service Fort Myers Is Fort Myers Shores’s Preferred Duct Repair & Sealing Company
We’ve earned a 4.9-star average across 91 verified reviews because Brian handles every job personally—no rotating crews, no franchise send-outs. Fort Myers Shores homeowners get 17 years of focused duct expertise, not a generalist contractor who added ductwork to a broader HVAC menu.
Our response time to Fort Myers Shores is typically same-day or next-morning. We’re familiar with the local landscape: the ranch homes off Orange River Boulevard, the manufactured home communities along the river corridor, and the post-Ian remediation patterns that left hidden mold problems in supposedly “fixed” duct systems. That local knowledge saves time and prevents repeat visits.
We carry professional-grade equipment—Rotobrush contact-vacuum systems, Nikro HEPA-rated units, and Abatement Technologies containment gear—that commercial and industrial contractors use, not the entry-level residential machines common in coupon services. We’re also authorized to supply and install Honeywell and Aprilaire air quality upgrades during the same visit, so if your duct repair reveals you need better filtration or humidity control, we handle it without a second appointment.
Our Duct Repair & Sealing Services in Fort Myers Shores
Duct Sealing
Most Fort Myers Shores homes lose significant cooling efficiency through leaky joints and disconnected runs, especially in original systems from the 1960s–1980s. We seal accessible ductwork with mastic sealant and reinforced tape rated for Florida’s humidity—never the cheap foil tape that peels off in our climate. For homes near the Orange River wetlands, where ambient moisture runs higher than coastal Fort Myers, proper sealing also blocks humid outside air from entering the return system. A typical sealing job in Fort Myers Shores runs $180–$350 for accessible basement or attic ductwork.
Flex Duct Repair
Original flex duct in Fort Myers Shores’s older homes degrades from the inside out. The plastic liner cracks, the fiberglass insulation compacts, and the outer jacket may look fine while the interior is collapsing. After Hurricane Ian, we see an additional failure mode: flex duct that absorbed contaminated floodwater now harbors mold between the liner and insulation layers. We responded to a 1970s ranch home on Orange River Boulevard where the homeowner thought a simple filter change would fix the musty smell. Our inspection revealed the original flex duct had absorbed sewage-laced floodwater; the interior liner was black with mold despite the intact exterior. We replaced the entire run with insulated metal duct and sealed all joints with mastic, restoring clean airflow. Flex duct replacement in Fort Myers Shores typically runs $280–$550 per run depending on length and accessibility.
Metal Duct Repair
When we replace damaged flex duct in Fort Myers Shores homes, we often upgrade to galvanized metal duct with external insulation—more durable in our climate and impervious to rodent damage. For existing metal duct systems, we repair separated seams, patch corrosion holes, and replace damaged sections. Metal duct repair in Fort Myers Shores generally costs $220–$480, with full section replacement at the higher end if flood damage has compromised the integrity.
Duct Insulation
Fort Myers Shores’s near-continuous cooling season—AC runs 10–11 months here—means duct insulation works harder than almost anywhere in the country. Saturated or compressed insulation doesn’t just waste energy; it becomes a mold reservoir. We install new fiberglass duct wrap or replace duct board with properly sealed metal systems, typically $320–$650 for a full attic or crawl space application in a Fort Myers Shores single-family home.

Common Duct Repair & Sealing Problems We See in Fort Myers Shores Homes
- Original flex duct from the 1960s–80s in Fort Myers Shores develops condensation and mold in the liner, especially after past flood events. The plastic inner liner cracks with age, and humid attic air infiltrates the fiberglass insulation. After Ian, many homes had this damage accelerated by floodwater absorption. The exterior jacket often looks intact while the interior is compromised.
- Manufactured homes on the Orange River corridor have under-floor ductwork that collects ground moisture and rodent debris, leading to leaks and contamination. These systems are notoriously difficult to access and rarely inspected until airflow drops or odors develop. We regularly find disconnected runs and chewed flex duct in these homes.
- Post-Ian cosmetic duct board repairs hide saturated insulation; the interior liner continues to grow mold, causing recurrent service calls in 33905. Homeowners were told their ducts were “cleaned” or “treated” after the flood, but the porous duct board material retains moisture and organic material that standard cleaning can’t reach. Replacement is often the only real solution.
- High humidity from the adjacent Orange River wetlands accelerates biological growth inside supply and return lines year-round. Even homes that never flooded face this. We see supply registers with black staining and return plenums with active mold colonies that standard filter changes won’t address.

FAQs — Duct Repair & Sealing in Fort Myers Shores
No—replacing only the insulation while keeping original duct board or flex duct liner is rarely sufficient in Fort Myers Shores’s post-Ian homes. The interior plastic liner of flex duct and the porous surface of duct board both absorb and retain contaminated water; mold continues growing on these surfaces even when new insulation is wrapped around them. We regularly find active mold colonies in “repaired” systems where only the exterior was addressed. Call (833) 345-6820 for an inspection that checks the liner itself—estimates are free.
Flex duct over 40 years old in Fort Myers Shores’s humid climate is almost always beyond cost-effective repair. The interior liner becomes brittle and cracked, the insulation compresses and loses R-value, and any post-Ian flood exposure means probable hidden mold. If you’re experiencing musty odors, uneven cooling, or rising energy bills in a 1960s–1980s Fort Myers Shores home, replacement with sealed metal duct is usually the better long-term investment. Call (833) 345-6820 and we’ll show you exactly what your system looks like inside.
Mastic sealant applied with a reinforced mesh backing outperforms tape in Fort Myers Shores’s persistent humidity. Standard foil tape fails within 2–3 years here; mastic remains flexible and bonded for 15+ years. We apply mastic to all new joints and connections during repair work, and we can re-seal existing accessible ductwork as a standalone service. For the highest-humidity homes near the Orange River wetlands, we may also recommend upgrading to fully sealed metal duct rather than re-sealing aging flex. Call (833) 345-6820 for a climate-specific recommendation.
Under-floor ductwork in manufactured homes along the Orange River corridor sits in a naturally moist environment with limited ventilation. Ground moisture rises through the vapor barrier, condenses on cool duct surfaces, and pools in low spots. Rodent activity common in these areas adds debris that blocks drainage and creates additional moisture traps. We address this by elevating and supporting duct runs properly, sealing all connections with mastic, and in some cases rerouting ductwork to reduce ground contact. Persistent wetness usually indicates the system needs structural repair, not just cleaning. Call (833) 345-6820 for an inspection.
Small leaks at seams or minor corrosion holes in accessible metal duct can often be patched or resealed without full section replacement, typically saving 40–60% versus replacement. However, if the metal is extensively corroded, if the leak is in a joint that has separated due to structural movement, or if flood exposure has compromised the interior coating, replacement is the more reliable fix. Brian will assess the specific location and extent of damage during your free estimate in Fort Myers Shores. Call (833) 345-6820 to schedule.
