If your registers smell musty, your upstairs rooms never reach temperature, or your energy bills have climbed without explanation, leaking ducts are the likely culprit.

We dispatch from our Cleveland office and serve Mentor proper, from the lakefront neighborhoods near Mentor Headlands to the subdivisions south of Route 2. Our crews know the local housing stock: the post-WWII ranches with unsealed sheet-metal joints, the split-levels from the 1970s with sagging flex runs, and the newer builds where builders’ tape has already dried out. That local knowledge matters because Mentor’s climate and geography create sealing problems you won’t find in inland Ohio cities. Lake-effect humidity, clay-heavy soils, and salt air near the shore all stress duct systems differently than the dry cold of a Cleveland winter alone.

Why Hollis Air Duct Cleaning Is Mentor’s Preferred Duct Sealing Company

Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. We operate under The Garrison Standard, which means written prices before any work starts, arrival inside the quoted window, and a 365-Day Done Right Promise on every job – if the seal fails or the problem returns within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.

Our technicians are background-checked and uniformed, and we use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies – the same tools commercial crews use on hospitals and schools. In Mentor specifically, we’ve handled enough lakefront homes to know that standard foil tape is usually the wrong fix for salt-air environments. We stock mastic compound and fiberglass mesh for permanent sealing, and we carry filtration products from Aprilaire and Guardsman when the job calls for upgraded protection.

Duct Sealing Services in Mentor

Duct Sealing Services in Mentor address the gaps, cracks, and disconnected joints that let conditioned air escape into your attic, crawlspace, or walls – and let humid, unfiltered outside air back in. In a typical Mentor home built between 1950 and 1990, we find 20 – 30% air loss through the duct system before it ever reaches the registers. That means your furnace and AC work harder, your bills climb, and rooms on the far end of the house never get comfortable. A proper sealing job starts with a camera inspection to map the damage, then closes every accessible joint with mastic and mesh for a permanent seal. In Mentor, whole-house duct sealing typically costs $450 – $950, with smaller partial-system repairs starting around $280.

Camera Inspection and Leak Mapping

We run a video scope through the full duct network before we seal anything. In Mentor’s older lakefront homes, this often reveals sand and salt buildup in return ducts, disconnected flex runs in attic spaces, and gaps at the air handler that a visual check from the basement would miss. The camera footage goes to you, not just us – you see what we see, and the written price reflects exactly what the footage shows.

Mastic Sealing Over Tape Repair

Foil tape and “duct” tape dry out, especially in Mentor’s humid summers and salt-air environments. We seal joints with water-based mastic compound reinforced with fiberglass mesh. It flexes with thermal expansion, won’t dry and lift, and lasts the life of the duct system. On lakefront jobs near Mentor Headlands, this is the only approach we’ve found that holds up against the grit and moisture those return ducts pull in.

Duct Insulation in Mentor

Duct Insulation in Mentor protects sealed ductwork from the temperature extremes in unconditioned spaces – attics that hit 140°F in July and crawlspaces below freezing in January. Even a perfectly sealed duct will bleed heat or cooling if the metal runs through an uninsulated attic. In Mentor’s climate, with Lake Erie humidity amplifying condensation problems, insulation is often the difference between a sealed system that performs and one that sweats moisture onto your ceiling drywall. Typical duct insulation jobs in Mentor run $380 – $720 for attic trunk lines, with crawlspace wrapping at the lower end and complex multi-zone systems at the higher end.

Condensation Control in Humid Attics

Mentor’s summer humidity, combined with cold AC air moving through metal ducts, creates condensation that drips onto insulation and ceiling joists. We wrap sealed ducts with formaldehyde-free fiberglass insulation and a vapor-barrier jacket, rated for the temperature differential we see in Northeast Ohio attics. This stops the sweating, protects your structure, and keeps the air reaching your registers at the temperature your thermostat set.

Crawlspace and Basement Runs

Homes in Mentor’s older neighborhoods often have supply ducts running through damp basements or vented crawlspaces. We insulate these runs with closed-cell foam or wrapped fiberglass, depending on access and moisture conditions. The goal is the same: the air that leaves your furnace arrives at the register at full temperature, without picking up basement chill or crawlspace damp along the way.

Trusted Brands We Service in Mentor

We stock parts and materials from Rotobrush, Nikro, Abatement Technologies, Aprilaire, and Guardsman – professional-grade equipment, not hardware-store substitutes. For Mentor customers, this means faster turnaround on jobs that need filtration upgrades or specialized sealing materials. If your system uses Aprilaire media filters or Guardsman UV components, we carry those lines and can integrate them with the sealing work without a second trip. Our Cleveland warehouse keeps mastic compound, fiberglass mesh, and insulation rolls in stock for the Lake County climate, so we’re not waiting on shipping while your ducts stay open.

Common Duct Sealing Problems We See in Mentor Homes

• Foil tape failure on lakefront returns. In the older neighborhoods near Mentor Headlands and the lakefront, technicians often find sand and salt residue tracked into return ducts from beach traffic. Those abrasive, hygroscopic particles hold moisture against bare sheet metal and chew through cheap foil tape on joints – a sealing problem inland communities rarely see. The tape looks fine in spring and lifts by August.
• Disconnected flex runs in 1990s subdivisions. Newer construction on Mentor’s south side typically uses flexible ducting, which can sag between supports and pull free at the collar. Homeowners notice weak airflow to back bedrooms and assume it’s the HVAC unit, not a duct that popped loose in the attic.
• Unsealed air handler connections. Many Mentor homes built between 1950 and 1970 have sheet-metal plenums joined to the furnace with a simple friction fit and a strip of tape. The thermal cycling of Northeast Ohio winters breaks that seal, pulling basement air into the supply and blowing heated air into the utility room instead of the living space.
• Attic ductwork sweating through degraded insulation. Mentor’s humid continental climate brings warm, humid summers and cold, snowy winters; the lake-effect snow and high summer humidity mean HVAC systems work hard year-round, and condensation in ducts can foster mold and mildew. When insulation compresses or tears, the duct metal sweats, and that moisture breeds microbial growth that homeowners smell before they see.
