Call (833) 962-5679 and you’ll reach a live person who can have a technician to your door, often within a few hours.
Cherry Hill’s housing stock isn’t like neighboring towns. The township was built almost entirely between 1958 and 1978 as one of New Jersey’s first large planned suburbs. That means an unusually dense concentration of homes share similarly aged original ductwork - sheet-metal systems with deteriorating fiberglass interior lining now 45 to 65 years old - across all three ZIP codes simultaneously. Where other communities grew organically over a century with mixed building eras, Cherry Hill’s single suburban boom created a saturation of deferred maintenance. Most single-family homes here hit the same stage of ductwork degradation at the same time. That’s not a theoretical observation. It’s what our technicians encounter in crawl spaces and attics here week after week.
Why Bellows Air Duct & Vent Co. of Philadelphia Is Cherry Hill’s Preferred Duct Repair & Sealing Company
We’ve earned our reputation in Cherry Hill by showing up when we say and leaving systems that don’t need a callback. Our Duct Repair & Sealing team has handled everything from routine mastic resealing in Greentree ranches to full metal trunk replacement in Cherry Hill Mall area colonials. Homeowners here know the difference between a company that quotes low and adds charges at the door, and one that puts the full price in writing before touching a tool. We’re the second kind.
Our response time to Cherry Hill is consistently fast because we maintain dedicated routing from our Philadelphia base across the Ben Franklin and Tacony-Palmyra bridges. Technicians arrive background-checked and uniformed, with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. Every job starts with a camera inspection and ends with one - a visual record, not just a claim.

Dennis Farrell, who leads Bellows Air Duct & Vent Co., set the standard back in 1984. The company’s named for the oldest air-moving tool there is. That straightforward approach still governs how we treat Cherry Hill customers.
Our Duct Repair & Sealing Services in Cherry Hill
Duct Sealing
Leaky ducts waste 20 to 30 percent of conditioned air in a typical Cherry Hill home, and that’s a conservative estimate for the 1960s and 70s builds here. We seal supply and return trunks, branch takeoffs, and plenum connections using mastic sealant and fiberglass mesh - the permanent fix, not tape that peels in attic heat. In Cherry Hill’s split-levels, especially in developments like Barclay Farm, we regularly find supply ducts routed through interior soffits where original seams have separated behind finished surfaces. Our camera inspection locates these hidden leaks without destructive access.
Metal Duct Repair
Cherry Hill’s original galvanized sheet-metal duct systems are reaching the end of their functional life. The fiberglass interior lining degrades, the metal corrodes at low points where condensation collects, and joist hangers fatigue after six decades of vibration. We repair separated trunks, replace deteriorated sections, and reinforce hangers. In one Barclay Farm split-level, we sealed a metal supply trunk that had separated at a joist hanger, using mastic and mesh to stop the conditioned-air loss. The homeowner had no idea the disconnect was behind a finished soffit until our crew used a Rotobrush camera inspection to find the leak.
Flex Duct Repair
Flex duct was sometimes added during later Cherry Hill renovations, and it’s vulnerable in ways rigid metal isn’t. Crawl-space runs get crushed when homeowners store boxes against them, collapsing the inner liner and blocking airflow. Kinks at sharp bends choke supply to second-floor rooms. We replace damaged flex sections with properly sized, fully extended runs supported every four feet per manufacturer specification.
Duct Insulation
Cherry Hill sits in the humid corridor of the Delaware Valley. Summer dew points climb high enough to cause condensation inside improperly insulated duct runs, especially in homes where attic or crawl-space ductwork lacks adequate vapor barriers. This persistent humidity, combined with heavy clay soils that keep moisture near foundations, means mold amplification inside neglected duct systems is a realistic concern for Camden County homes. We repair or replace deteriorated insulation with foil-faced fiberglass or closed-cell foam wrap, properly sealed at all seams.
Mastic Sealant Application
Mastic is the only acceptable sealant for permanent duct repair, and it’s our standard on every Cherry Hill job. Brush-applied mastic with reinforcing mesh outlasts tape by decades, especially in attics where temperature swings cause expansion and contraction. We see the consequences of skipped mastic in Cherry Hill regularly: 50-year-old sheet-metal joints that failed at branch takeoffs, blowing conditioned air into unfinished spaces for years before anyone noticed the utility bills climbing.

Common Duct Repair & Sealing Problems We See in Cherry Hill Homes
- Drywall return-air chases pulling contaminated air. Split-levels and ranches from Cherry Hill’s 1960s-70s planned developments frequently have return-air chases built from framed drywall cavities rather than dedicated sheet-metal ducts. Those cavities pull unconditioned air, insulation fibers, rodent debris, and decades of dust from wall and floor framing directly into the air handler. Many homeowners don’t realize this until a technician opens the system.
- Failed mastic joints at branch takeoffs. In 50-year-old sheet metal, the original sealant has dried and cracked. Attic temperature swings accelerate the failure. We find branch takeoffs blowing 20-degree air into insulation instead of into bedrooms.
- Crushed flex duct in crawl spaces. Cherry Hill’s heavy clay soils keep crawl spaces damp and underused, which makes them storage areas. Boxes and seasonal items get pushed against flex runs, collapsing the inner liner. The HVAC system works harder. The room stays cold.
- Condensation damage from Delaware Valley humidity. Attic and crawl-space ductwork without proper vapor barriers sweats all summer. The fiberglass insulation gets wet, compacts, and falls away. Metal corrodes. Mold establishes. It’s a slow-motion failure that accelerates once it starts.

FAQs - Duct Repair & Sealing in Cherry Hill
Temperature cycling in your attic and the original construction methods of the 1960s and 70s are the culprits. Cherry Hill split-levels were built with sheet-metal trunks hung from joists with minimal allowance for expansion; decades of heating and cooling seasons have fatigued the hangers and cracked the original sealant. The fix is permanent mastic and mesh reinforcement, not tape. Call (833) 962-5679 and we’ll camera-inspect to find every separation - estimates are free.
Yes, and it’s often the most important repair we make in Barclay Farm properties. We seal the chase interior with a liner or coating, upgrade the filter grille to prevent bypass, and verify with a camera that the system is pulling from conditioned space only. The improvement in air quality and system efficiency is immediate. Call (833) 962-5679 to schedule - estimates are free.
Yes, if your attic or crawl-space ductwork has damaged or missing insulation. Cherry Hill’s summer dew points regularly reach levels that cause condensation on cold supply ducts. Wet insulation fails, metal corrodes, and mold risk becomes real. We repair or replace insulation with proper vapor-barrier materials. Call (833) 962-5679 for an assessment - estimates are free.
Very possibly. Ranches in Cherry Hill’s 08034 and 08003 areas often have long attic duct runs with multiple access points for leakage. A typical system loses 20 to 30 percent of conditioned air to unconditioned spaces; in 50-year-old original ductwork, we’ve measured losses above 40 percent. Sealing pays for itself in reduced runtime. Call (833) 962-5679 and we’ll pressure-test and camera-inspect - estimates are free.
Yes. Our technicians are familiar with Honeywell and Aprilaire air-quality components integrated into duct systems. If your repair involves accessing or relocating these units, we handle it without requiring a separate HVAC call. Parts are stocked for fast turnaround. Call (833) 962-5679 to confirm compatibility with your specific model - estimates are free.
