Why Bellows Air Duct & Vent Co. of New York Is Hollis’s Preferred Duct Repair & Sealing Company
Hollis homeowners don’t call us for flash. They call because their neighbor on 204th Street mentioned we showed up on time, explained the problem in plain English, and the price matched the quote.

Our Duct Repair & Sealing Services in Hollis
Duct Sealing
Sealing is often the most cost-effective fix for Hollis homes, and it’s where we start most jobs. Those sharp offsets in retrofitted duct runs create chronic air leaks at splice points, wasting energy and pulling attic contaminants into living spaces. We use mastic sealant at every joint, not tape that dries and fails. A typical duct sealing job in Hollis runs $280-$450 for a single system, and most are completed in one visit. Done right, and backed in writing for 90 days.
Flex Duct Repair
Flex ducts in Hollis take a beating. Crushed in knee-wall crawl spaces, degraded by residual heat near old boiler rooms, choked with decades of debris. We recently sealed a flex-duct splice in a living room knee-wall on 204th Street in Hollis; the original conversion from steam had left a 140° bend choked with 50 years of debris. We applied mastic sealant at the joints and insulated the newly exposed duct with Guardsman wrap, restoring full airflow without tearing open the finished wall. Flex duct repair in Hollis typically costs $180-$340. If the damage is too extensive, we’ll tell you straight and quote replacement upfront.
Metal Duct Repair
The original metal plenums in Hollis basements are solid but often poorly spliced to newer flex runs. We repair separated seams, reinforce corroded sections, and ensure transitions don’t leak where old meets new. Metal repair runs $220-$480 in this market, depending on whether we can reach the problem from the basement or need to access through finished spaces.
Duct Insulation
Uninsulated or degraded ductwork in unconditioned Hollis attics and crawl spaces loses 20-30% of its heating and cooling energy before air ever reaches your rooms. We install fresh insulation, often using Guardsman wrap or equivalent, sized to the irregular spaces these retrofitted systems occupy. Insulation work in Hollis ranges from $350-$650 for partial systems to $800-$1,400 for full replacement. We’ll show you the camera footage so you can decide what makes sense.

Trusted Brands We Service in Hollis
We stock parts and materials from Rotobrush, Honeywell, and Guardsman, the same brands serious HVAC contractors specify for Queens installations. That means faster turnaround for Hollis customers. No waiting on a warehouse in Ohio to ship a fitting that matches your 1960s plenum. Our trucks carry mastic sealant, flex duct in common diameters, insulation wrap, and transition fittings sized for the non-standard configurations we find in this area’s converted housing stock. If we don’t have it, we know who locally does, and we’ll get it same-day rather than make you wait.
Common Duct Repair & Sealing Problems We See in Hollis Homes
- Sharp offsets in retrofitted duct runs cause chronic air leaks at splice points, wasting energy and pulling attic contaminants into living spaces. These convoluted paths, forced through finished walls during mid-century steam-to-forced-air conversions, simply don’t occur in purpose-built duct systems.
- Decades-old mastic joints dry and crack in narrow knee-walls, allowing conditioned air to escape into uninsulated crawl spaces. Hollis’s 1920s-1950s brick homes with finished basements make these areas nearly impossible for homeowners to inspect themselves.
- Flex ducts spliced near original boiler rooms degrade faster due to residual heat and asbestos-wrapped pipes nearby, requiring careful assessment before any repair. This combination is a recognized hazard pattern in this specific vintage of Queens housing, and our technicians are trained to identify and work around it safely.
- Humid Queens summers with high ambient particulate from dense street traffic mean duct interiors cycle between damp, mold-conducive conditions and dry, dust-stirring forced-air heat, accelerating biofilm and debris buildup compared to less urban climates. Annual inspection catches this before it becomes a health issue.

FAQs - Duct Repair & Sealing in Hollis
Steam-to-forced-air conversions in the 1960s-1980s shoehorned ductwork through finished walls, cramped attic knee-walls, and irregular crawl spaces, creating sharp offsets and splice points that standard suburban duct layouts simply don’t produce. These convoluted runs trap debris, stress joints, and leak conditioned air into wall cavities for decades. We see this pattern across Hollis’s 1930s-1950s brick housing stock. Call (833) 348-8789 for a free camera inspection and exact quote.
Yes, we repair crushed flex ducts in Hollis knee-walls regularly, and most jobs are completed in a single visit. We access the damage through existing openings when possible, replace the crushed section with properly sized flex duct, seal with mastic at every joint, and insulate with Guardsman wrap to prevent condensation. Typical cost is $180-$340 per run. If the crawl space is too restricted for safe repair, we’ll explain your options upfront. Call for a free estimate.
Yes, our technicians are trained to identify and work safely around asbestos-wrapped pipes, a recognized hazard pattern in Hollis’s converted basement plenums. We do not disturb asbestos-containing materials; instead, we design repairs that avoid contact while restoring duct integrity. If hazardous material removal is needed, we coordinate with licensed abatement contractors and will tell you before any work begins. Safety assessment is included in every free estimate. Call (833) 348-8789 to schedule.
Mastic sealant applied with proper extension tools is the best method for sealing joints in finished Hollis basements, because it doesn’t require opening walls and forms a permanent, flexible bond that tape can’t match. We verify the seal with camera inspection and airflow testing. Typical cost for targeted mastic sealing in accessible basement areas runs $180-$280. If the joint is completely buried, we’ll show you the camera footage and discuss whether limited access or alternative routing makes more sense. Free estimates, no pressure.
Signs include sweating ducts in summer, rooms that never reach temperature despite the system running, musty smells from registers, and energy bills that climb without explanation. We camera-inspect and thermal-scan to show you exactly where insulation has degraded or was never installed properly. Partial insulation repair in Hollis runs $350-$650; full system replacement runs $800-$1,400. The camera footage lets you decide what fits your budget. Call (833) 348-8789 for a free inspection and upfront quote.
