Buffalo’s lake-effect humidity and long heating season push HVAC systems harder than most of the country. In the neighborhoods around University at Buffalo, from the converted Victorians near Elmwood Avenue to the mid-century ranches in Amherst and the student-heavy blocks around Bailey Avenue, we’ve found that ductwork gaps don’t just waste money. They pull in attic dust, basement moisture, and outdoor allergens that circulate through every room. Our crews serve University at Buffalo from our New York City dispatch office, with scheduling built around the academic calendar that drives so much of the local housing market. We know when landlords need units sealed before August move-ins, and we know which complexes near UB’s North Campus have the original flexible ductwork that tends to sag and separate at the seams.

Why Hollis Air Duct Cleaning Is University at Buffalo’s Preferred Duct Sealing Company

We’ve worked in University at Buffalo long enough to recognize the specific duct problems this market produces. The Garrison Standard means we arrive inside our quoted window, price the job in writing before touching anything, and leave the site clean. That discipline matters especially here, where many customers are property managers coordinating access between tenants or parents helping students settle into off-campus housing.

Our technicians are background-checked and uniformed, and we send the same crew names before they arrive so you know who is walking through your door. The 365-Day Done Right Promise covers every seal we apply: if a joint fails or a leak reopens within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.

Phones are answered by a live person 24 hours a day, 7 days a week. When you’re trying to get a unit sealed before a lease starts or between semesters at University at Buffalo, that accessibility matters more than a coupon price that jumps once the van is in your driveway.

Duct Repair in University at Buffalo

Duct Repair in University at Buffalo addresses the physical damage that sealing alone cannot fix: crushed flexible runs in basements, rusted galvanized sections in older homes near Main Street, and disconnected collars where vibration has worked joints loose. We see this work most often in the 1960s-era apartment complexes between UB’s South Campus and the Kensington Expressway, where original metal ductwork has corroded from decades of Buffalo humidity cycling through the system. Typical duct repair in University at Buffalo runs $300 – $800 depending on accessibility and material, with written pricing agreed before any cutting or replacement begins.

Section Replacement and Patching

When a duct section is too corroded or collapsed to seal, we cut out the damaged run and splice in new galvanized or flexible duct matched to the existing system. In University at Buffalo’s converted student rentals, we often find previous owners have patched with duct tape that degrades within a season; we use proper mastic and mechanical fasteners that hold through Buffalo’s temperature extremes.

Collar and Connection Rebuilds

The joint where a supply duct meets the main trunk is a common failure point, especially in systems that cycle on and off frequently through harsh winters. We rebuild these connections with sheet-metal screws, draw bands, and sealed mastic beds that flex without separating.

Air Duct Sealing in University at Buffalo

Air Duct Sealing in University at Buffalo closes the gaps and leaks that allow conditioned air to escape into attics, crawl spaces, and wall cavities. We apply duct sealing mastic, a thick, fiber-reinforced compound that remains flexible at temperature extremes, along with metal-backed tape at all joints and register boots. Most University at Buffalo homes lose 20 – 30% of heated or cooled air through these leaks, which means your furnace and AC work harder, your bills climb, and rooms farthest from the air handler stay uncomfortable. Whole-system air duct sealing in University at Buffalo typically costs $450 – $1,200, with smaller partial-system jobs starting around $300.

Mastic Application at Joints and Seams

We brush mastic into every longitudinal seam, joint, and register connection, building a continuous seal that tape alone cannot achieve. In the older housing stock near University at Buffalo’s South Campus, where galvanized ducts have been modified repeatedly over decades, this method seals the accumulated gaps from multiple renovation phases.

Register Boot and Plenum Sealing

The connection between your wall or floor register and the duct behind it is often the leakiest point in the system. We seal these boots to the drywall or subfloor and to the duct itself, stopping the suction that pulls in dust and unconditioned air from wall cavities.

Trusted Brands We Service in University at Buffalo

Our equipment roster includes professional-grade tools from Rotobrush and Abatement Technologies, plus filtration and sealing products from Aprilaire and Guardsman. We stock mastic, metal-backed tapes, and replacement duct sections sized for the systems common in University at Buffalo’s housing stock, which means most repairs don’t wait on parts orders. When a landlord near UB’s North Campus needs a unit sealed before a Saturday move-in, that local inventory matters. The same applies to the older homes in University Heights and the apartment blocks along Main Street, where original equipment specifications vary widely and generic hardware-store supplies rarely fit correctly.

Common Duct Sealing Problems We See in University at Buffalo Homes

• Humidity-damaged flexible duct in basements and crawl spaces. Buffalo’s high summer humidity and frequent lake-effect precipitation saturate the thin insulation wrapping flexible duct runs, causing the inner liner to sag and tear. We replace these with properly supported, sealed runs rated for damp conditions.
• Disconnected collars in high-turnover student rentals. In the converted homes and apartment complexes near Bailey Avenue and Winspear Avenue, repeated HVAC cycling and occasional rough maintenance have loosened the sheet-metal screws and draw bands at duct joints. We rebuild these connections with proper mechanical fasteners and sealed mastic beds.
• Leaky register boots in plaster-and-lath walls. The older homes south of UB’s South Campus often have register openings cut through plaster that has cracked away from the boot, creating a gap that pulls in wall cavity air. We seal these with expandable foam backing and mastic, not tape that will fail within a season.
• Corroded galvanized trunk lines in pre-1970s housing. The mid-century ranches and Cape Cods in Amherst and Kenmore, many now rented to University at Buffalo students, have original galvanized steel ducts that rust from the inside out. We patch salvageable sections and replace failed runs, sealing all new work to the existing system.
