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 Lorain
We seal ductwork in Lorain homes where the real problem isn’t dirty ducts, it’s ducts that were never built to hold pressure in the first place. If you’re living in one of the city’s pre-1950 homes near the lakefront, you might be losing heated and cooled air through joints that cracked decades ago, or pulling basement dampness and debris straight into your living space. We dispatch crews from our Cleveland office and serve Lorain neighborhoods directly, including the lakeshore streets south of Route 6, the older worker cottages off Oberlin Avenue, and the mid-century homes around Amherst and Elyria roads. Call (361) 326-5060 for a free estimate. We’ll show you what the camera sees before we quote a price.
Why Hollis Air Duct Cleaning Is Lorain’s Preferred Duct Sealing Company
We’ve been working in Lorain long enough to know that a standard duct cleaning estimate doesn’t tell the whole story. Our technicians carry camera systems that inspect inside the runs before we write a price, because we’ve learned that sealing disconnected collars and cracked joints is often the repair that makes cleaning worth doing at all. Roy Castellanos built this operation on The Garrison Standard: written prices, written guarantees, and technicians who arrive uniformed, background-checked, and inside the quoted window. Our 365-Day Done Right Promise covers every sealing job in writing. If the seal fails or the joint reopens within a year, we come back and make it right at no charge, including a free second visit. No negotiation. No runaround.
Air Duct Sealing in Lorain
Air Duct Sealing in Lorain is often the repair that has to happen before a proper cleaning can begin, especially in the city’s older housing stock where original gravity-furnace ductwork was never engineered for forced-air systems. We use mastic sealant and reinforced mesh to close gaps at joints, collars, and plenum connections, then verify the seal with pressure testing. A typical whole-system sealing job in Lorain runs $450 – $850 for a standard single-family home, though homes with extensive disconnected runs or original 1920s – 30s metalwork south of Route 6 can run higher once we see what the camera reveals.
Camera Inspection Before Sealing
We don’t guess. Every sealing job starts with a video inspection inside the duct runs so we can show you the disconnected collars, crushed sections, or cracked joints before we quote. In Lorain’s pre-1950 homes, this step often reveals problems a standard cleaning estimate would miss entirely.
Mastic and Mesh Application
We seal with brush-applied mastic and fiberglass mesh, not tape. Tape fails in damp basements. Mastic stays flexible, bonds to metal and existing sealant, and holds through the humidity swings that Lorain’s lakefront location throws at it.
Duct Sealing Services in Lorain
Duct Sealing Services in Lorain from Hollis cover everything from single joint repairs to whole-system resealing after camera inspection and source removal. We don’t price per vent or per linear foot. We quote one flat price per system, agreed in writing before any work starts, based on what we find during inspection. Most Lorain homeowners with standard post-war ranch or cape-style homes see whole-system sealing in the $450 – $650 range. Homes with original gravity-furnace ductwork, multiple disconnected runs, or foundation-shift damage from freeze-thaw cycles typically fall in the $650 – $850 range, with complex cases running higher.
Source Removal Before Sealing
We won’t seal over debris. If inspection finds heavy accumulation, we clean first using Rotobrush rotary agitation and Nikro negative-air machines under HEPA filtration, then seal. Sealing over contamination traps moisture and makes mold growth worse.
Pressure Testing After Sealing
We verify our work. After mastic application cures, we run a pressure test to confirm the system holds. If it doesn’t, we find the leak and fix it before we leave. That’s part of the written price.

Trusted Brands We Service in Lorain
Our sealing work is backed by equipment and materials from Abatement Technologies, Rotobrush, and Guardsman, the same names commercial crews specify. We stock mastic, mesh, and collar hardware sized for the older duct dimensions common in Lorain homes, not just modern flex-duct fittings. That means faster turnaround for homeowners in Sheffield Lake, Elyria, Avon, and Amherst who need sealing done right the first time, without waiting on special-order parts.
Common Duct Sealing Problems We See in Lorain Homes
- Original gravity-furnace ductwork south of Route 6. These 1920s – 30s systems were never sized for forced-air blowers. The metal can’t hold positive pressure, so joints blow apart and collars disconnect. We seal what can be sealed and flag what needs replacement.
- Freeze-thaw foundation shifts cracking joints at the floor line. Lorain’s lakefront winters freeze the ground deep, then spring thaw shifts pre-1950 foundations enough to separate duct runs where they enter the wall. Camera inspection finds these; surface sealing misses them.
- Uninsulated runs in damp basements condensing and molding. Summer humidity off Lake Erie hits 80% and higher. Cold air in uninsulated metal ductwork condenses, grows mold, and prevents sealant from bonding. We dry, clean, then seal.
- Retrofitted flex-duct connections failing at original plenums. When forced-air systems were added to old gravity furnaces, installers often used tape and hope. Twenty years later, those connections are pulling basement air into the supply. We cut back to solid metal and reseal with mastic.
Pricing for Duct Sealing in Lorain, OH
Whole-system duct sealing in Lorain typically runs $450 – $850, with most standard homes falling in the $450 – $650 band. What pushes a job toward the higher end: original gravity-furnace ductwork that needs collar replacement before sealing, multiple disconnected runs from foundation shift, or pre-sealing source removal where decades of debris block the mastic bond. We don’t do per-vent pricing or teaser coupons that balloon once we’re inside. The price is written down before we start, and it doesn’t move at the door. Call (361) 326-5060 for a free estimate. We’ll inspect with the camera, show you what we found, and give you a flat price you can take to another company for comparison.

FAQs About Duct Sealing in Lorain
Original 1920s – 30s gravity-furnace ductwork in this area was never engineered for forced-air blowers, so disconnected runs and crushed sections can’t hold pressure for effective cleaning. We seal or repair these first, then clean. Call (361) 326-5060 for a camera inspection and written quote.
Pre-1950 homes here have uninsulated, undersized metal runs in damp basements, plus foundation shifts from freeze-thaw cycles that crack joints at the floor line. Camera inspection almost always finds hidden separations a surface check would miss. We’ll show you the footage before we price the repair.
Yes, but only if sealing follows proper source removal. Sealing disconnected runs and cracked joints stops the system from pulling basement air, lead paint dust, and mold spores into living spaces. We clean first with HEPA-contained negative-air methods, then seal. The 365-Day Done Right Promise covers our work in writing.
We inspect with video camera systems, clean with Rotobrush rotary agitation and Nikro negative-air machines under HEPA filtration, and seal with brush-applied mastic and fiberglass mesh verified by pressure testing. Our Duct Sealing crews follow The Garrison Code on every job: arrive inside the window, price in writing, work by the book, leave the site clean.
Lake Erie keeps summer humidity above 80% for weeks at a time. Cold air in uninsulated basement ductwork condenses, grows mold, and prevents sealant from bonding properly. We dry and clean metal surfaces before applying mastic, or the seal peels within a season. Call (361) 326-5060 for an inspection that accounts for local conditions.
