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 North Madison
Most North Madison homes pull water from the same sandstone aquifer that leaves scale on your showerhead and mineral dust in your ducts. That well-water environment, combined with the original rigid metal ductwork common in the ranches and split-levels along Route 20 and Hubbard Road, creates a sealing problem you won’t find in Cleveland suburbs on municipal water. We’re the Duct Sealing crew that knows the difference. Dispatch runs through our Cleveland office, but our technicians live and work this Lake County corridor regularly. Call us at (361) 326-5060 for a free written estimate.
Why Hollis Air Duct Cleaning Is North Madison’s Preferred Duct Sealing Company
We’ve been sealing ducts in Madison Township since 2004, long enough to know which 1970s split-levels on the lake ridge still have foil-backed insulation turning to dust in the return plenum. Roy Castellanos built this operation on The Garrison Standard: written price before we touch anything, background-checked uniformed technicians, and a 365-Day Done Right Promise that puts our guarantee in writing, not in a handshake.
Our phones are answered by a live person 24 hours a day, 7 days a week. No callback queues, no “leave a message and we’ll get back to you.” When you schedule Duct Sealing in North Madison, we arrive inside the quoted window, price the job in writing, and leave the site clean. That’s The Garrison Code, and it’s how we’ve earned our reputation in Lake County.
North Madison isn’t a city with a mayor and a water treatment plant. It’s a tight community where word travels at the township hall and the hardware store on North Ridge Road. We don’t burn those relationships.
Duct Insulation in North Madison
Duct Insulation in North Madison addresses a problem most homeowners don’t notice until their winter heating bill spikes or their basement ductwork sweats all July. The mid-century ranches and 1970s split-levels that dominate this area were built with fiberglass-lined or externally wrapped rigid metal ducts, and decades of Lake Erie humidity swings have degraded that insulation into the airstream. We remove deteriorated material, seal the metal seams with mastic, then install fresh foil-faced fiberglass wrap or closed-cell foam where appropriate.
A typical Duct Insulation job in North Madison runs $850 – $1,400 for a full basement or crawlspace system, depending on linear footage and accessibility. Homes with original 1960s ductwork in tight crawlspaces trend toward the higher end.
When Insulation Fails in Lake County Homes
The lake-effect snow and summer humidity around North Madison create expansion and contraction cycles that separate tape seams and compress fiberglass over time. We inspect for condensation stains on basement ceilings and temperature gaps between rooms, both signs the thermal barrier has failed.
Mineral Dust and Biofilm Buildup
The private wells here produce water that feeds whole-house humidifiers, and that mineral-rich moisture leaves a film inside ducts that standard insulation can’t adhere to properly. We clean before we insulate, using Nikro negative-air equipment to establish a clean surface.
HVAC Duct Sealing in North Madison
HVAC Duct Sealing in North Madison stops the conditioned air you’re paying for from leaking into your attic, crawlspace, or the gap between your basement and first floor. In the ranches along Chapel Road and the split-levels near Madison Park, we regularly find 15 – 25% air loss through gaps at plenum connections, register boots, and failed flex-duct joints. Our crew seals these with UL-181 rated mastic and reinforced mesh, then pressure-tests the system to verify the fix.
Typical HVAC Duct Sealing in North Madison costs $650 – $1,100 for a whole-house system, with smaller partial repairs starting around $350. We quote the full price in writing before any work begins.
Pressure Testing After the Seal
We don’t guess. After sealing, we run a duct blaster or manometer test to measure leakage in CFM at 25 Pascals. You see the before and after numbers yourself, documented on the invoice.
Return Duct Priority in Older Homes
The original foil-backed insulation in 1970s split-levels along the lake ridge often deteriorates directly into the return airstream, pulling fiberglass and dust through your furnace. We inspect returns first in these homes, because a leaky return pressurizes your walls and attic with unfiltered air.
Trusted Brands We Service in North Madison
We stock parts and sealing materials from Honeywell, Aprilaire, and Abatement Technologies for North Madison jobs, which means most repairs don’t wait on a Cleveland warehouse run. Our rotary brush systems from Rotobrush and negative-air machines from Nikro handle the pre-seal cleaning that mineral-heavy well-water environments demand. When your humidifier’s Aprilaire pad has coated the duct interior with scale, we’ve got the right cleaning agents and the right mastic to bond despite it. Fast turnaround matters in Lake County, where winter heating loads don’t forgive a week-long parts delay.
Common Duct Sealing Problems We See in North Madison Homes
- Original metal ductwork with failed tape seams. The ranches built in the 1950s – 70s along Route 20 used rigid galvanized duct with cloth-backed tape that dries and falls off after 40 years of lake-effect humidity cycles. We find gaps blowing heated air directly into crawlspaces.
- Split-level return ducts with disintegrated foil insulation. The 1970s split-levels near the lake ridge suffer from foil-backed fiberglass that turns to powder after decades of humidity swings, contaminating the air your family breathes.
- Crawlspace flex-duct chewed by rodents or crushed by storage. North Madison’s older homes with dirt-floored crawlspaces often have sagging flex-duct that’s been damaged by moisture, varmints, or decades of homeowners stacking boxes on it.
- Mineral scale from well-water humidifiers preventing mastic adhesion. The sandstone aquifer water that feeds whole-house humidifiers here leaves a hard scale inside ducts that cheap sealants won’t bond to. We clean with Nikro equipment before applying professional-grade mastic.
