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 Duct Sealing Across Fruit Cove
Duct sealing in Fruit Cove typically runs $400 – $1,200 per system depending on accessibility, with most homes in this St. Johns River community needing two to three systems addressed. We dispatch crews to Fruit Cove from our Miami office, and our Duct Sealing team is familiar with the flex-duct-in-unconditioned-attic construction that’s standard here from the 1980s through the 2010s builds. Call (361) 326-5060 for a written estimate before any work starts.
We’ve worked enough homes off Fruit Cove Road and along the riverfront to know the pattern: damp crawl spaces, saturated flex duct after summer storms, and the musty vent odor that follows. That’s why we also offer Fruit Cove Dryer Vent Cleaning for homes dealing with lint buildup and vent blockages. This isn’t inland Jacksonville. The river keeps humidity high even in January, and sealing ducts here requires a different sequence than drier markets. Our crews arrive uniformed, background-checked, and equipped with Rotobrush rotary systems and Nikro negative-air machines. The price is written down before we touch anything, and every job carries our 365-Day Done Right Promise in writing.
Why Hollis Air Duct Cleaning Is Fruit Cove’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our Duct Sealing in Fruit Cove work follows The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. Fruit Cove homeowners aren’t looking for the lowest teaser quote. They’re looking for a crew that shows up, does what they said they’d do, and stands behind it for a full year.
Our 365-Day Done Right Promise means if the seal fails or the musty odor returns within twelve months, we come back at no charge. That includes a free second visit, not a negotiation. Our technicians are background-checked and uniformed; you’ll know who’s arriving before they walk in. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for scheduling.
We don’t price by the vent or bait with a low coupon that balloons once the van is in your driveway. One flat price per system, agreed in writing before work begins. For Fruit Cove’s larger riverfront homes with multiple air handlers, this matters. Per-vent pricing would triple the invoice on a three-system house with long attic runs. We scope each system separately, document what we find, and give you a single written number per system.
Duct Insulation in Fruit Cove
Duct Insulation in Fruit Cove addresses a problem most homeowners don’t see until their energy bill spikes or a room stays stubbornly hot. In this river-adjacent community, flexible ductwork runs through unconditioned attics and crawl spaces where summer heat and year-round humidity attack from both sides. Without proper insulation, cooled air warms before it reaches your vents, and condensation forms on the duct exterior, dripping into insulation and framing. We remove degraded insulation, seal all seams with mastic, then wrap runs with fresh insulation rated for Florida’s climate.
Most Fruit Cove homes built between 1980 and 2010 need insulation replacement if the original flex duct is still in place. Original insulation compresses, tears, or grows mold in damp crawl spaces. A typical Duct Insulation job in Fruit Cove runs $300 – $800 per system depending on linear footage and attic accessibility. Riverfront custom homes with long runs off Fruit Cove Road often land at the higher end. Standard suburban tract homes in the Julington Creek area typically fall mid-range.
When Insulation Fails in Humid Crawl Spaces
Fruit Cove’s crawl spaces stay damp even in winter because of river proximity and high water tables. Insulation that touches damp ground or sits against sweating ductwork becomes a mold vector within a season. We inspect crawl space conditions before wrapping any new insulation, and we recommend moisture remediation if the source isn’t addressed. Wrapping wet ducts is a waste of your money.
Attic Heat Gain on Long Riverfront Runs
Custom homes along the St. Johns often have duct runs exceeding fifty feet through unconditioned attic space. Without proper insulation R-value, that cooled air gains ten to fifteen degrees before reaching the vent. We calculate heat load per run and specify insulation thickness accordingly, not a one-size-fits-all wrap.
HVAC Duct Sealing in Fruit Cove
HVAC Duct Sealing in Fruit Cove stops the conditioned air you’re paying for from leaking into attics, crawl spaces, and wall cavities before it reaches your rooms. In this market, we see the same failure pattern: original flex duct from the 1990s and 2000s with gaps at plenum connections, torn sleeves at sharp bends, and tape that’s dried and peeled in attic heat. A typical HVAC Duct Sealing job in Fruit Cove costs $400 – $1,200 per system, with most two-system homes falling in the $800 – $1,800 range total. Three-system riverfront properties can run $1,500 – $3,000 depending on linear footage and accessibility.
Our process starts with a camera inspection so you see what we see. We then perform source removal under negative pressure with HEPA filtration if the ducts are contaminated, treat any mold or mildew with antimicrobial, dry the seams completely, and seal with mastic and reinforced tape. We finish with a post-seal pressure test and provide documentation: before photos, leak locations, seal points, and after verification. You get a written copy; we keep records for warranty.
The Moisture-First Rule for River-Adjacent Homes
Fruit Cove’s river-adjacent crawl spaces stay damp even through winter, so flex duct in those unconditioned spaces wicks moisture year-round. Sealing alone fails unless seams are dry and treated for mold before tape or mastic goes on. We’ve seen competitors seal over wet flex in January, only to get a mold callback by June. We don’t skip the drying step. Ever.
Per-System Pricing for Multiple Air Handlers
Many Fruit Cove homes have two or three systems, often with the third added during a garage conversion or upstairs addition. Treating this as one “house price” misses hidden leaks in the second and third air handlers. We price per system, inspect per system, and document per system. You know exactly what each air handler cost to seal and what condition it was in.
Trusted Brands We Service in Fruit Cove
Our crews carry professional-grade equipment and parts from Rotobrush, Nikro, Abatement Technologies, Aprilaire, and Guardsman. For Fruit Cove homeowners, this means we don’t order parts and make you wait. We stock mastic, reinforced foil tape, insulation wrap, and antimicrobial treatments sized for Florida flex duct on every van. If your system uses Aprilaire filtration components or Guardsman moisture barriers, we have compatibility specs on hand. The same tools commercial crews use on hospital and school ductwork, brought to your driveway. Fast turnaround because the part isn’t three days out; it’s in the van.
Common Duct Sealing Problems We See in Fruit Cove Homes
- Musty odor after summer thunderstorms. After a typical summer afternoon thunderstorm, Fruit Cove homeowners often notice a musty odor from their vents. Humid air penetrates gaps in attic ductwork, and the combination of moisture and organic dust triggers mold growth within days. Sealing without antimicrobial treatment and moisture source identification guarantees a repeat call.
- Original flex duct in pre-2000 homes with no maintenance history. Many homes in the Julington Creek and Fruit Cove Road corridors still run 1990s-era flex duct that’s never been inspected. The sleeve material degrades, tape adhesive fails, and connections at the plenum separate. We find 20 – 30% air loss standard in these systems.
- Three-system homes scoped as one price. A riverfront property with a main system, upstairs addition, and garage conversion has three separate duct networks, often with different ages and conditions. Quoting one lump price almost always means the least accessible system gets skipped or under-sealed.
- No documentation of work performed. Ducts are out of sight. Without before photos, leak location maps, and post-seal pressure readings, a homeowner has no proof the work happened. We provide written documentation on every Fruit Cove job because you can’t verify what you can’t see.
Pricing for Duct Sealing in Fruit Cove, FL
Honest pricing for duct sealing in Fruit Cove runs $400 – $1,200 per HVAC system. A typical two-system home falls in the $800 – $1,800 range. Three-system properties, common in larger riverfront builds, typically run $1,500 – $3,000 total. Duct Insulation adds $300 – $800 per system depending on linear footage and whether we’re working in a tight crawl space or open attic.
What moves the number: accessibility (crawl space height, attic hatch location), linear footage of ductwork, contamination level requiring source removal before sealing, and whether insulation replacement is bundled. We don’t quote per vent because that’s how teaser prices become surprise invoices. One flat price per system, written down, agreed before work starts. Estimates are free.

FAQs About Duct Sealing in Fruit Cove
Because many homes here have two or three separate HVAC systems, often added during expansions, and each has its own duct network with different accessibility and leak severity. A single “whole house” price almost always under-scopes the harder-to-reach system. We price per system so nothing gets skipped. Call (361) 326-5060 for an exact quote per air handler.
You should receive before photos of leak locations, a written seal-point map, post-seal pressure test results, and an itemized invoice per system. We provide all four on every Hollis job. Ductwork is hidden; documentation is your proof the work happened and your reference if a warranty issue arises.
Only if sealing is combined with moisture source control and antimicrobial treatment. Sealing gaps stops humid air intrusion, but if mold is already established or the crawl space stays damp, the odor returns. We inspect for active contamination before sealing and treat it if found. Call (361) 326-5060 if you’re getting that post-storm musty vent smell.
No. Sealing traps existing mold inside with your airflow. We perform source removal under negative pressure with HEPA filtration, apply antimicrobial treatment, dry seams completely, then seal. Sealing over active mold is a callback waiting to happen in Fruit Cove’s humid climate.
Usually yes, especially for attic and crawl space runs. Sealing stops air leakage; insulation stops thermal gain and condensation. In Fruit Cove’s unconditioned spaces, you need both for efficiency and mold prevention. We assess insulation condition during our camera inspection and bundle both if needed. One flat price per system, agreed in writing.
