Fort Myers homeowners deal with a unique combination of challenges: year-round humidity that degrades flex duct insulation, salt air corrosion on metal ductwork near the coast, and cooling systems that run 280+ days annually, pressurizing every seam and joint. When your ducts leak, you’re not just losing conditioned air — you’re pulling attic heat, moisture, and particulates into your living space. We’ve built our reputation on diagnosing the full picture, not patching symptoms. With a 4.9-star average across 91 verified reviews, we’ve earned the trust of homeowners who want the job done correctly the first time by the same person who quoted it.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, seams, and connection points where conditioned air escapes into your attic, crawl space, or wall cavities. In Fort Myers, we regularly find that 20–30% of cooled air never reaches the intended rooms due to leakage at plenum connections and register boots. Brian applies mastic sealant and professional-grade foil tape — not the cheap cloth tape that fails in our humidity — and verifies results with a pressure differential test before leaving.
Flex Duct Repair
Flex duct is common in Fort Myers homes built from the 1980s forward, but our heat and humidity cause the inner liner to sag, tear, or detach from collars entirely. We see collapsed flex runs in attics that reach 140°F in July, suffocating airflow to master bedrooms and back offices. Brian repairs or replaces damaged sections using properly sized, insulated flex duct with mechanical connections that won’t pull apart during our storm-season pressure changes.
Metal Duct Repair
Galvanized metal ductwork in older Fort Myers homes — particularly in McGregor and the historic districts — corrodes at seams and develops whistle-inducing gaps. We cut out rusted sections, fabricate replacement pieces on-site, and seal with mastic for a permanent fix. Unlike generalist HVAC contractors who might recommend full replacement, Brian evaluates whether targeted metal duct repair restores integrity at a fraction of the cost.
Duct Insulation
Uninsulated or degraded duct insulation in a Fort Myers attic is essentially trying to cool your home with a radiator. We install fresh fiberglass or closed-cell insulation wraps that maintain R-6 to R-8 values even in our punishing attic environments. Proper insulation also prevents condensation that leads to mold growth — a real concern when attic dew points spike during our August afternoon thunderstorms.
Mastic Sealant Application
Mastic is the professional standard for durable duct sealing — a thick, fiber-reinforced compound that remains flexible for decades. Brian brushes mastic into every longitudinal seam, transverse joint, and penetration point, then allows proper cure time before pressurizing the system. In Fort Myers, we prefer water-based mastic formulations that handle our humidity without trapping moisture, applied with techniques refined over 17 years of duct-specific work.
Air Leak Repair
Air leaks often hide behind drywall or above insulation, detectable only through systematic pressure testing and thermal scanning. We pressurize your duct system and use smoke pencils or infrared cameras to pinpoint exactly where your money is escaping — no guesswork, no unnecessary demolition. Once located, Brian repairs leaks with the appropriate method for that duct type and location, then re-tests to confirm the seal.

Brands We Service for Duct Repair & Sealing
We’ve worked extensively with Aprilaire duct components and air quality systems, including their whole-home humidifier and ventilation control integrations that tie directly into duct infrastructure. Our familiarity with Aprilaire’s specifications means we can repair duct connections to their units without compromising warranty coverage or airflow design — and we stock common Aprilaire fittings for same-day completion.
Abatement Technologies containment and air-scrubbing equipment is part of our standard job setup, particularly when we’re sealing ducts in older Fort Myers homes that may have disturbed particulates during the repair process. Whether your system includes Aprilaire, Abatement-compatible components, or any other make, Brian has the hands-on experience to repair and seal it properly. We also work with Guardsman protective products when duct access requires cutting into finished surfaces that need restoration.
Signs You Need Duct Repair & Sealing Right Now
- Rooms that never cool evenly. If your southwest-facing bedroom in Fort Myers stays 8–10 degrees warmer than the rest of the house despite a running AC, you likely have a disconnected or crushed duct run. This isn’t a thermostat problem — it’s a distribution failure that wastes energy and strains your compressor.
- Dust accumulation around supply registers. Excessive dust blowing from vents often indicates leaks in return ductwork, which pulls attic air laden with fiberglass particles and insect debris directly into your breathing space. In our sandy soil environment, this accelerates filter clogging and indoor air quality degradation.
- Unexplained humidity spikes indoors. Fort Myers already battles 75%+ outdoor humidity; if your home feels sticky even when the AC runs continuously, leaking supply ducts may be drawing humid attic air into the system. Proper sealing restores the closed loop your dehumidification depends on.
- Energy bills climbing without rate increases. When conditioned air leaks into unconditioned spaces, your system runs longer cycles to achieve setpoint. We’ve seen Fort Myers homeowners drop their summer electric bills by 15–25% after comprehensive duct sealing — the savings often pay for the repair within two cooling seasons.
- Visible duct damage or disconnected runs in attic or crawl space. If you can see torn flex duct, rusted metal, or gaps at connections, the damage is almost certainly worse in areas you can’t access. Brian uses borescope cameras to inspect hidden runs and provides photo documentation of what needs attention.
Our Duct Repair & Sealing Process — Step by Step
- 1
System inspection and pressure testing. Brian arrives with a Rotobrush contact-vacuum system and diagnostic gauges to measure static pressure and airflow at each register. We identify leaks, restrictions, and insulation failures before proposing any work — you’ll see the exact problems, not a generic sales pitch.
- 2
Photo documentation and written estimate. We provide dated, geotagged photos of damaged ductwork and a line-item estimate with no hidden charges. Every repair is explained in plain terms: what we’re fixing, why it matters, and what happens if you delay.
- 3
Targeted repair and sealing execution. Brian performs all work personally, using Nikro HEPA-rated equipment to maintain clean air during the repair process. Flex duct gets proper support straps every 4 feet (not the sagging runs we commonly find), metal gets mastic-sealed seams, and all connections are mechanically secured.
- 4
Post-repair verification testing. We re-pressurize the system and measure airflow improvements at each register. If we don’t achieve measurable results, we keep working until we do — this is standard practice, not an upsell.
- 5
Sanitizing and final walkthrough. Where appropriate, we apply air quality sanitizing treatment to eliminate mold spores or bacteria disturbed during repair. Brian reviews all work with you, shows before-and-after photos, and explains any maintenance that extends the repair life in Fort Myers conditions.
How Much Does Duct Repair & Sealing Cost in Fort Myers?
A typical duct sealing job for a 1,500–2,500 square foot Fort Myers home runs $275–$550 when we’re addressing accessible plenum connections, register boots, and main trunk seams. Flex duct repair or partial replacement adds $180–$340 per run depending on length and attic accessibility. Full metal duct repair with custom fabrication ranges $450–$850 for most residential applications. These are 2024–2025 price ranges reflecting current material costs and our single-technician efficiency — no office overhead passed to you.
Several factors move the needle: attic temperature (summer work in 140°F spaces takes longer and requires hydration breaks), duct accessibility (blown-in insulation adds prep time), and the extent of corrosion or pest damage we discover. The best way to avoid overpaying is getting a detailed, written estimate with photo evidence before authorizing work — which is exactly what Brian provides at every free estimate. We don’t charge diagnostic fees, we don’t bill by the hour with open-ended totals, and we don’t sell repairs you don’t need.
Every estimate includes: full system inspection, photo documentation, line-item pricing, and a clear statement of what’s included versus what might require additional discovery. Call (833) 345-6820 to schedule — estimates are free and carry no obligation.
