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.
Fast, Reliable Duct Sealing Across Naples Park
Duct sealing in Naples Park typically runs $350 – $850 for a whole-home system, and most jobs are completed in a single visit. If your vents are blowing conditioned air into the attic or your summer power bills are climbing faster than your neighbors’ on 111th Avenue, sealed ducts usually pay for themselves within two cooling seasons.
We’ve been crawling through the low attics and tight soffits of Naples Park since Hollis Air Duct Cleaning opened in 2004. Our dispatch team coordinates from our Miami office, but the crew that shows up at your door knows this grid of sandy lots between Vanderbilt Beach and U.S. 41. They know the 1950s concrete-block ranches with original ductwork, the 1970s stucco additions with flex duct slapped in by a prior property manager, and the seasonal homes on 108th Avenue North that sit sealed up for eight months while humidity breeds mold in every unsealed joint. When you call (361) 326-5060, a live person answers, and we schedule you into a real arrival window, not a four-hour guessing game.
Why Hollis Air Duct Cleaning Is Naples Park’s Preferred Duct Sealing Company
Naples Park homeowners don’t need another coupon in the mailbox promising a $49 whole-house special that balloons to $900 once the van is in the driveway. We’ve built our reputation here by doing the opposite. Every Hollis job starts with a written price before any tool touches your ductwork, and that number doesn’t move at the door. Our Duct Sealing in Naples Park crews arrive in uniform, background-checked, and on time, because The Garrison Standard doesn’t allow for mystery technicians or missed windows.
Our 365-Day Done Right Promise covers every duct sealing job in writing. If a sealed joint fails, a mastic application cracks, or a tape edge lifts within twelve months, we come back and make it right at no charge, including the second visit. That guarantee is backed by the Garrison Partners family, not a corporate call center three states away. Our technicians carry professional-grade equipment from Nikro and Abatement Technologies, the same negative-air systems and sealing tools commercial crews use in hospitals and schools. And when you call (361) 326-5060, day or night, a live person picks up. No voicemail loops. No “we’ll call you back Monday.”
Duct Sealing Services in Naples Park
Duct Sealing Services in Naples Park address a problem most homeowners don’t know they have: conditioned air leaking into attics, crawl spaces, and wall cavities before it ever reaches your living room. In a typical Naples Park ranch home with short duct runs and low attic clearance, even a handful of unsealed joints can waste 20 – 30% of your cooling output. That’s money you’re paying FPL to cool your insulation.
Our Duct Sealing process starts with a pressure test to locate every leak, followed by mechanical sealing with mastic compound and reinforced tape rated for Florida humidity. We don’t use duct tape, the gray cloth stuff that dries out and peels in six months. We use products from Honeywell and Aprilaire designed for permanent adhesion in high-heat, high-moisture environments. A typical whole-home duct sealing in Naples Park runs $350 – $850 depending on system size and accessibility.
Seasonal-Home Preparation
Naples Park’s snowbird cycle creates a specific sealing challenge. A home that sits closed from May through October develops pressure imbalances and seal degradation from thermal expansion and contraction. We inspect and reseal systems before owners return, so that first blast of AC doesn’t carry attic dust and mold spores into the bedroom.

Post-Renovation Sealing
Many Naples Park properties have seen piecemeal renovations where a bathroom was added or a kitchen was bumped out, and flex duct was routed by a general contractor without proper sealing at the new junctions. We trace these amateur additions and seal them to code.

Duct Insulation in Naples Park
Duct Insulation in Naples Park is not a luxury, it’s a thermal necessity. When your attic hits 140 degrees in July, uninsulated or poorly insulated ductwork acts like a radiator in reverse, heating your cooled air before it reaches the vent. In the tight, low attics common to Naples Park’s 1960s and 1970s housing stock, there’s often no room for bulky fiberglass wraps, so we use closed-cell foam and reflective barrier products that fit where conventional insulation won’t.
A typical duct insulation job in Naples Park runs $400 – $950 for a whole system, with smaller partial jobs starting around $250. We price by the linear foot and by the difficulty of access, not by some opaque “per-vent” formula that changes when the technician arrives. The work usually takes four to six hours, and we photograph before and after conditions so you can see what was covered and what gaps remain.
Condensation Control
Naples Park’s humidity doesn’t just threaten your ducts from the outside. Cold air moving through uninsulated metal ductwork creates condensation on the exterior, which drips onto drywall and breeds mold. Proper insulation eliminates the temperature differential that causes sweating.
Energy Recovery
FPL rates have climbed steadily, and Naples Park’s older homes were never designed for today’s cooling loads. Insulated ducts reduce the runtime your compressor needs to maintain temperature, which extends equipment life and trims your monthly bill.
Trusted Brands We Service in Naples Park
We carry sealing and insulation products from Honeywell, Aprilaire, and Abatement Technologies, brands specified by commercial HVAC engineers for durability in humid climates. Our Nikro negative-air machines allow us to test system pressure before and after sealing, so you have documented proof of improvement, not just a handshake. We stock common register sizes and flex duct diameters used in Naples Park’s mid-century housing stock, which means most jobs don’t wait on parts. If your system uses an unusual configuration, our Miami office coordinates same-day or next-day supply runs. We don’t ask you to take a day off work and then tell you we’ll be back next week.
Common Duct Sealing Problems We See in Naples Park Homes
- Original metal ductwork with deteriorated tape joints. The 1950s and 1960s ranches along 107th Avenue and 109th Avenue North were built with sheet metal ducts sealed with cloth-backed tape that has dried and failed after sixty years of heat cycling. We remove the old residue and apply mastic rated for decades of service.
- Flex duct crimps and disconnections from prior DIY repairs. Property managers and homeowners have often patched Naples Park ductwork with hardware-store flex duct and zip ties, creating leaks at every connection. We replace these with properly supported runs and sealed collars.
- Mold growth in unsealed plenums after seasonal vacancy. A closed-up home on 108th Avenue North with no air circulation becomes a petri dish. When we seal ducts in these properties, we first inspect the plenum and returns for biological growth that would recontaminate the system.
- Corroded register grilles from salt-laden Gulf air. Naples Park’s proximity to Vanderbilt Beach means salt aerosol infiltrates attic vents and attacks metal components. We identify corrosion that has compromised seal integrity and recommend replacement where necessary.
Pricing for Duct Sealing in Naples Park, FL
Whole-home duct sealing in Naples Park typically costs $350 – $850. Partial sealing of a specific problem zone runs $180 – $340. Duct insulation runs $400 – $950 for a full system, with smaller jobs starting around $250. These are honest ranges for our market, not teaser prices designed to get a foot in the door.
What moves you within these ranges? System size, attic accessibility, and the condition of existing ductwork. A 1,200-square-foot ranch with a wide attic hatch and exposed metal ducts is straightforward. A home with a sealed attic, blown-in insulation covering every joint, or multiple layers of amateur repairs takes more time and care. We assess this during your free estimate, put the price in writing, and that’s what you pay. No per-vent add-ons. No “we found another problem” surcharges. We also offer Air Duct Cleaning in Naples Park and Dryer Vent Cleaning in Naples Park, and many homeowners bundle services for efficiency. Call (361) 326-5060 for your free estimate.
