Why Bellows Air Duct & Vent Co. of New York Is Strathmore’s Preferred Duct Repair & Sealing Company
We’ve been driving to Strathmore since 1984, back when the Garden State Parkway exit numbers changed and these homes were only twenty years old. Now they’re sixty to seventy, and the same families - or their children - still call us. Our reputation here was built on showing up when we say and leaving the job done right, backed in writing for 90 days.
Strathmore customers specifically mention our camera inspections in reviews. They like seeing the before and after, especially when we’ve pulled out rust flakes or degraded liner debris they didn’t know was circulating through their bedrooms. We’re not the cheapest call you can make. We’re the call you make once.
Response time to Strathmore averages under 90 minutes during business hours, and our office answers live 24 hours a day - no voicemail, no app. That matters when your return trunk has separated and your house smells like metal every time the blower cycles.
Our technicians are background-checked, uniformed, and trained on the exact failure patterns Strathmore’s coastal environment produces. They know to check for salt corrosion at seam joints, mineral deposits on duct walls, and fiberglass liner degradation that inland crews rarely encounter.
Our Duct Repair & Sealing Services in Strathmore
Duct Sealing with Mastic Sealant
Strathmore’s original sheet-metal trunks were joined with snap-lock seams and minimal sealant in the 1950s and 60s. After six decades of thermal expansion, contraction, and salt-air corrosion from Raritan Bay, those seams open up. We seal every accessible joint with professional-grade mastic, not tape that peels in humid crawl spaces. A typical mastic sealing job for a Strathmore ranch runs $280-$450 and drops measurable airflow loss at the plenum. We camera-verify the seal before we leave.
Metal Duct Repair
This is the service we perform most often in Strathmore. The galvanized steel supply and return trunks in these mid-century homes rust from the inside out, accelerated by humidity that stays above 80% RH through July and August. On a recent job for a ranch home on Bermuda Way, our crew found the original galvanized supply trunk had separated at the main seam due to 70 years of coastal humidity and salt infiltration, dumping rust flakes into the airstream. We sealed the entire trunk with mastic, replaced a corroded flex run with insulated aluminum duct, and installed a new Aprilaire filter cabinet at the return to catch residual debris. Metal duct repair in Strathmore typically ranges from $450-$900 depending on linear feet and accessibility.
Flex Duct Repair
The flex runs connecting trunks to registers in Strathmore’s slab-adjacent crawl spaces often sag, tear, or pull loose at collars. Critters sometimes nest in them. We replace damaged flex with insulated aluminum duct rated for damp locations, not the cheap vinyl products that degrade in two seasons near the bay. Most flex replacements in Strathmore run $180-$340 per run.
Duct Insulation
Uninsulated or degraded ductwork in Strathmore’s crawl spaces loses conditioned air to the damp earth below and gains humidity every summer. We wrap repaired trunks and new flex runs with formaldehyde-free fiberglass insulation or closed-cell foam sleeves, depending on clearance. Proper insulation pays for itself in reduced run times and less microbial growth. Duct insulation in Strathmore typically adds $320-$580 to a repair job.

Trusted Brands We Service in Strathmore
We stock parts and equipment from Honeywell, Aprilaire, and Abatement Technologies on every Strathmore truck. These are the same brands serious HVAC contractors specify, not the no-name imports that fail in coastal conditions. Our Aprilaire filter cabinets and media upgrades install directly into existing return plenums, giving Strathmore homeowners better particle capture without major modifications. Guardsman corrosion inhibitors go on every metal repair we make within two miles of the bay. Because we carry inventory locally, most Strathmore repairs don’t wait for a parts run.
Common Duct Repair & Sealing Problems We See in Strathmore Homes
- Joint separation in original 1950s sheet-metal trunks. Sixty-plus years of thermal cycling and salt-air corrosion weaken snap-lock seams, especially in slab-adjacent crawl spaces that never dry out. We find complete separations dumping conditioned air into dirt more often than you’d expect.
- Interior rust flaking from aging galvanized ducts. Persistent Raritan Bay humidity above 80% RH keeps duct interiors damp for hours after AC cycles end. That moisture accelerates oxidation, and the rust flakes break loose to circulate through registers.
- Degraded fiberglass duct liner debris from original 1960s construction. The fibrous liner material common in that era breaks down, bonds to duct walls with mineral deposits from winter salt-laden storms off the bay, and requires active remediation rather than standard cleaning.
- Corroded flex duct collars and sagging runs in low-clearance crawl spaces. Original flex connections in Strathmore’s ranches weren’t built to handle decades of coastal dampness. The vinyl degrades, the wire helix rusts, and the run collapses or pulls free.

FAQs - Duct Repair & Sealing in Strathmore
Every 10-15 years for inspection, with sealing every 15-20 years under normal conditions. Strathmore’s salt-air and 80%+ summer humidity accelerate corrosion, so we recommend a camera inspection every 8-10 years for homes with original 1950s-60s ductwork. Catching joint separation early prevents the rust-flaking and debris problems that cost more later. Call (833) 348-8789 to schedule - estimates are free.
Yes, but our crew is equipped for them. The ranches along Bermuda Way and similar streets have 18-24 inch clearances that require specialized tools and patience. We’ve worked these spaces for decades and carry compact equipment specifically for tight coastal crawl spaces. Most repairs still complete in one visit. Call (833) 348-8789 to discuss access at your address.
Metal trunk seam sealing and localized replacement of corroded galvanized sections. The original supply and return trunks in these homes have reached end-of-life from thermal cycling and salt corrosion. Mastic sealing restores integrity where metal is sound; replacement is necessary where rust has penetrated through. Call (833) 348-8789 for a camera inspection to determine which your home needs.
Yes, significantly. Proper insulation prevents condensation on cool duct surfaces during humid summer months, which reduces the damp conditions that promote microbial growth. For Strathmore homes within a mile of Raritan Bay, we recommend insulation on every repair or replacement we perform. The upgrade typically adds $320-$580. Call (833) 348-8789 for specifics on your system.
It is in homes built during the 1950s-60s construction window. The original fiberglass duct liner degrades over 60-70 years, and Strathmore’s coastal humidity plus winter salt deposits cause it to bind to duct walls rather than simply falling away. Standard cleaning won’t remove it. We remediate this with mechanical agitation and HEPA extraction before sealing or repairing the metal underneath. Call (833) 348-8789 if your home dates to this era and you’ve never had the liner assessed.
