Fast, Reliable Duct Repair & Sealing Across Fort Myers Beach
Duct repair and sealing in Fort Myers Beach typically costs $280–$650 for most residential jobs, with same-day response available across Estero Island and the 33931/33932 ZIP codes. We’re usually on-site within 45 minutes of a call from Fort Myers Beach — close enough that Brian handles the work personally, not a subcontractor driving from Cape Coral or Naples.
Our Duct Repair & Sealing team knows this island’s housing stock intimately: the 1970s beach cottages on Estero Boulevard, the mid-rise condos along Carlos Pointe, and the wave of post-Hurricane Ian rebuilds that went up fast between 2023 and 2024. That local knowledge matters because Fort Myers Beach ducts fail differently than anywhere else in Lee County. Saltwater corrosion, construction debris trapped in rushed rebuilds, and aggressive mold strains from Ian’s surge create repair scenarios you won’t find in Iona or Cypress Lake — and certainly not in inland markets.
Call (833) 345-6820 for a free estimate. Brian Rivera, our owner and lead technician, will inspect your system personally and tell you honestly whether sealing, repair, or replacement makes sense.
Why Keystone Air Duct Cleaning Service Fort Myers Is Fort Myers Beach’s Preferred Duct Repair & Sealing Company
We’ve earned a 4.9-star average across 91 verified reviews by showing up and doing the work right — not by dispatching random technicians from a franchise pool. In Fort Myers Beach specifically, that reputation was built house by house after Hurricane Ian, when homeowners needed someone who understood salt-damaged duct systems, not a generalist with a vacuum and a coupon.
Brian Rivera has 17 years of focused duct and HVAC cleaning experience. He handles every job personally, using professional-grade Rotobrush contact-vacuum systems and Nikro HEPA-rated equipment — the same tools industrial contractors use, not entry-level residential gear. For Fort Myers Beach customers, this means he’s spotting corrosion patterns, construction debris issues, and mold contamination that less experienced techs miss entirely.
Our response time to Fort Myers Beach averages under 45 minutes because we’re based in Fort Myers proper, not sending crews across multiple counties. We carry Honeywell and Aprilaire products on the truck, so if your sealed ducts need filtration or purification upgrades, we handle it in the same visit.
Clean, seal, and sanitize in one call. That’s the difference between a specialist and a generalist.
Our Duct Repair & Sealing Services in Fort Myers Beach
Duct Sealing with Mastic Sealant
Fort Myers Beach’s year-round humidity and salt-laden air punish duct seams that were merely taped or poorly sealed during original installation. We apply professional-grade mastic sealant — a thick, fiber-reinforced compound that remains flexible through decades of thermal cycling — to every joint, register boot, and plenum connection. In post-Ian rebuilds, we’ve found mastic sealing especially critical: contractors rushing to certificate-of-occupancy deadlines often skipped proper sealing, leaving gaps that bleed cooled air into hot attics and wall cavities. A typical mastic sealing job in Fort Myers Beach runs $280–$420 for a single-system home.
Flex Duct Repair
The post-2022 rebuild wave brought thousands of new flex duct runs to Fort Myers Beach, many installed before final construction cleanup. Drywall dust, fiberglass particles, and spray foam debris now sit trapped inside those flexible liners, restricting airflow and providing substrate for mold. We repair crushed, disconnected, or debris-loaded flex duct by replacing damaged sections with new insulated flex, properly supported to prevent sagging, and sealed with mastic at every connection. Flex duct repair in Fort Myers Beach typically ranges from $180 for a single run to $520 for multiple replacements in larger homes.
Metal Duct Repair
Here’s where Fort Myers Beach diverges sharply from every nearby market. Hurricane Ian’s 12–18 foot storm surge submerged metal duct systems in saltwater that standard corrosion protocols never anticipated. Surviving metal ducts on Estero Island are corroded in ways unseen in Naples or Cape Coral — pitting at seams, galvanic degradation at supports, and salt-crystal intrusion that continues to degrade metal years after the flood. We recently serviced a post-Ian rebuild on Estero Boulevard where the original ducts were coated in marine sediment and mold. After sealing all seams with mastic and replacing a corroded section, the homeowner saw their cooling efficiency return to normal. Metal duct repair in Fort Myers Beach runs $340–$650 when sections can be salvaged; severely corroded systems require full replacement.
Duct Insulation Repair and Replacement
Salt air corrodes duct insulation facings and vapor barriers faster on Estero Island than anywhere in Lee County. Once the facing fails, humid Gulf air saturates the fiberglass, collapsing R-value and creating mold reservoirs. We replace compromised insulation with properly sealed, high-humidity-rated materials, restoring thermal performance and preventing condensation that leads to further damage. Duct insulation work in Fort Myers Beach typically costs $220–$480 depending on accessible linear footage.

Common Duct Repair & Sealing Problems We See in Fort Myers Beach Homes
- Saltwater-corroded metal ducts that cannot be effectively sealed. Ian’s surge didn’t just wet ducts — it initiated electrochemical corrosion that continues degrading metal from the inside out. We see this in surviving cottages on Carlos Pointe and older condo units: seams that look sealable until pressure-testing reveals through-wall pitting. Replacement, not repair, is the honest call.
- Flex ducts installed pre-final-cleanout in rapid rebuilds, trapping construction debris. The 2023–2024 construction rush produced a counterintuitive problem: brand-new duct systems in freshly built vacation rentals already clogged with drywall dust and spray foam particles. Contractors sealed ductwork before final cleanup, so the first “cleaning” these systems need is actually debris removal and re-sealing.
- Aggressive mold strains from hurricane flooding that recontaminate sealed ducts. Fort Myers Beach’s post-Ian mold environment includes species that standard cleaning protocols don’t fully address. Sealing alone traps living colonies; we treat with antimicrobial agents before sealing to prevent re-growth through the new mastic barrier.
- Salt-air degradation of duct insulation facing, accelerated by year-round HVAC operation. Unlike seasonal markets where ducts rest half the year, Fort Myers Beach systems run constantly, thermal-cycling insulation facings until they crack. Once compromised, humid air infiltrates and destroys R-value within a single cooling season.

FAQs — Duct Repair & Sealing in Fort Myers Beach
Replacement is often necessary for metal duct systems that were submerged in saltwater, while sealing alone suffices for flex ducts with intact cores but poor seam integrity. We evaluate corrosion depth with borescope inspection before recommending either approach — call (833) 345-6820 for a free assessment.
No, sealing traps debris inside; we must first clean or replace debris-loaded flex ducts, then seal properly. This two-step process is now standard for 2023–2024 rebuilds across Fort Myers Beach’s new construction inventory — call for an inspection to determine if your ducts were commissioned pre-cleanup.
Salt-laden air corrodes metal seams and degrades insulation facings roughly twice as fast as inland Lee County locations, shortening effective service intervals and requiring corrosion-resistant materials for lasting repairs. We specify salt-rated fasteners and antimicrobial sealants specifically for Fort Myers Beach’s marine environment.
Replace if borescope inspection reveals through-wall pitting or galvanic corrosion at supports; repair with mastic sealing if damage is superficial and structural integrity remains intact. Brian makes this call honestly after hands-on inspection — no upsell pressure, just 17 years of evaluating salt-damaged ductwork.
We use professional-grade mastic compounds and specify Abatement Technologies containment equipment during remediation work; for air quality upgrades completed during the same visit, we stock Honeywell and Aprilaire filtration and purification products. All materials are selected for durability in high-humidity, salt-air environments.
