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.

AfterFast, Reliable Air Duct Repair Across St. Augustine
Air duct repair in St. Augustine, FL typically runs $275 – $640 depending on whether we’re patching a disconnected run, sealing a corroded plenum, or replacing a section of damaged flex duct.

If your vents are blowing weak, your energy bill keeps climbing, or you’ve caught that musty smell coming through the registers, call us at (980) 447-2498 for a written estimate before any work starts.

Ductwork Repair in St. Augustine
Ductwork repair in St. Augustine usually means finding where the system is leaking, disconnected, or corroded and fixing it where it matters: at collars, plenum seams, and transitions. In this city, the failure points show up faster than inland because salt-laden air off the Matanzas River eats through metal collar fittings in a decade or less. A disconnected flex duct in a Davis Shores attic or a rusted seam behind a Lincolnville closet chase is not something a homeowner can spot from the register. It takes a trained tech with camera inspection equipment to locate the actual breach.
Sealing and reconnecting
When a supply run pulls loose from its boot or a plenum seam opens up, conditioned air dumps into the attic or crawlspace instead of your living room. We reconnect the run, seal the connection with mastic and foil tape rated for high-humidity environments, and verify the fix with a pressure reading. Most sealing jobs in St. Augustine run $275 – $450 depending on access and how many connections need work.
Corrosion repair at fittings
Salt air corrodes the galvanized collars and plenum seams that join duct sections. Pinholes in a plenum seam pull humid attic air straight into your supply stream, which is why a bedroom in an Anastasia Island beach bungalow can smell musty even after the air handler’s been serviced. We replace corroded collars, re-seam the plenum, and wrap the repair to prevent recurrence. Figure $320 – $580 for a typical corrosion repair with real access.
Duct Replacement in St. Augustine
Duct replacement in St. Augustine is sometimes the only honest fix when a run is collapsed, torn beyond patching, or so colonized with mold that cleaning leaves the duct jacket compromised. In the historic district and Lincolnville, ductwork was retrofitted into crawlspaces, dropped ceilings, and closet chases that were never engineered for it, and those runs routinely fail long before a standard flex-duct system in a Palencia or World Golf Village home would. Replacing those runs means fabricating custom transitions on site, because nothing off-the-shelf matches the angles those old buildings force.
Replacing damaged flex runs
Pinched, torn, or water-damaged flex duct in an attic or floor cavity gets pulled out and replaced with new insulated flex, properly supported and sealed at both ends. A typical single-run replacement in St. Augustine runs $380 – $640, and the price includes removal, disposal, and verification.
Custom transitions for retrofit systems
This is where St. Augustine is different. Pre-WWII homes here often have ductwork shoehorned through spaces no engineer ever planned for, so a failed transition needs to be built, not bought. We fabricate the fitting on site or in our shop, then fit it, seal it, and wrap it. Custom work runs $450 – $720 depending on the geometry and time involved, and you see the written price before the first cut.
Trusted Brands We Service in St. Augustine
We work with equipment from Rotobrush and air-quality products including Aprilaire, Abatement Technologies, and Guardsman, so whatever system your St. Augustine home has, we have the right tools for the job. Because we keep common fittings, collars, and flex duct lengths stocked specifically for the housing types we see across St. Johns County, turnaround on most St. Augustine repairs is faster than waiting on a supplier delivery. We also work with Nikro equipment for remediation jobs where source removal matters. The brand on your air handler doesn’t matter as much as the person repairing the ductwork, and our techs are trained to work on all of them.
Common Air Duct Repair Problems We See in St. Augustine Homes
- Salt-corroded collars and plenum seams. The Atlantic on one side and the Matanzas River on the other means the air here carries salt year-round. Galvanized fittings rust through faster in St. Augustine than almost anywhere else in North Florida.
- Disconnected runs in retrofitted historic homes. Ductwork forced through Lincolnville closet chases and dropped ceilings shifts and separates over decades. A run can be pumping conditioned air into a wall cavity for years before anyone notices.
- Mold colonization in vacation-rental ductwork. Short-term rentals on Anastasia Island cycle through dozens of tenant turnovers without maintenance. We regularly open plenums in these properties and find microbial growth that started one or two renovations ago.
- Restricted returns straining the blower. Debris and collapsed flex in return runs make the air handler work harder, which shortens blower motor life and spikes energy bills. The first sign is often a whistling noise at the return grille.
Pricing for Air Duct Repair in St. Augustine, FL
A straightforward repair in St. Augustine runs $275 – $450. Replacing a damaged flex run typically lands between $380 and $640. Custom transitions for historic-district retrofit systems run $450 – $720 because the work is fabricated, not pulled off a shelf. What changes the price is access, not mystery markups: a crawlspace with fifteen inches of clearance costs more in labor than a walk-in attic, and a plenum tucked behind original plaster costs more than one in an open garage chase. You get the written price before the job starts, every single time. Call (980) 447-2498 for a free estimate. We serve St. Augustine and surrounding St. Johns County.

FAQs About Air Duct Repair in St. Augustine
Historic-district ductwork in St. Augustine was retrofitted into pre-WWII masonry and wood-frame buildings through crawlspaces, dropped ceilings, and closet chases that were never engineered for ventilation. Repairs in those buildings routinely require custom-fabricated transitions rather than off-the-shelf parts, and access is often limited to a single crawlspace hatch or a closet chase too tight for standard tools. That labor and fabrication time is what drives the difference, not markup. Jacksonville’s western suburbs are mostly newer flex-duct homes with open attics and standard layouts, so repairs go faster. Call (980) 447-2498 and describe your home; we’ll give you an honest range before we send anyone out.
No. Fogging sprays a chemical mist into the ducts, but it does not remove the source of the mold: the matted organic growth bonded to the duct wall, the debris pile in the return, or the moisture that feeds it. In St. Augustine’s humidity, fogging alone leaves the colonization in place, and it regrows as soon as the condensation cycle returns. A real fix requires source removal under negative pressure with HEPA filtration, followed by sealing the leaks and fixing whatever is feeding moisture into the system. We do not sell fogging as a mold remedy because it is not one. Call (980) 447-2498 if you want the actual problem removed, not misted over.
Anastasia Island vacation rentals should have ducts inspected at least once a year, and more often if they turn over weekly or biweekly during season. We consistently find that HVAC maintenance in short-term rentals gets deferred across dozens of tenant turnovers, and by the time a guest complains about a musty smell, the inside of the return plenum often shows years of accumulated debris and microbial growth. An annual inspection lets us catch a failing collar or a disconnected run before the blower motor burns out. If you manage a rental on Anastasia Island, call (980) 447-2498 to schedule an inspection with a written report.
Salt air corrodes the galvanized steel fittings that connect duct sections: collars, plenum seams, takeoffs, and boots. Pinholes form, humid attic or crawlspace air gets pulled into the supply stream, and the unit starts conditioning outside air while pushing musty, salty moisture through your registers. In St. Augustine, the Matanzas River keeps this process going year-round, and we replace corroded collars on homes less than ten years old. A pre-season inspection can catch early corrosion before it becomes a full replacement. Call (980) 447-2498 to have a tech check your fittings.
Yes, but it takes different techniques. In Lincolnville and the historic district, we work in crawlspaces with sixteen inches of clearance, dropped ceilings, and closet chases that were never built for maintenance access. We use camera scopes to map the run, then cut the smallest access panel needed to do the repair properly. We seal the chase under negative pressure with HEPA filtration during any remediation work, and we replace the panel so it looks clean. No job is too tight, and we will tell you up front if a repair in your home will take extra labor because of access. Call (980) 447-2498 for a free estimate.
