Richard Anderson — owner and lead technician at Landmark Air Duct Cleaning Service New York — brings 20 years of specialized ductwork experience directly to Irvington’s unique pre-war housing stock. We’re familiar with the tight crawl spaces, steep hillside lots, and retrofitted forced-air systems that define homes from the riverfront up to Main Street.

Our Duct Repair & Sealing team knows Irvington’s 10533 ZIP inside and out — from the Victorian-era homes lining Clinton Avenue to the Craftsman bungalows tucked above the Hudson. We’ve worked in basements where the headroom barely clears five feet, and we’ve traced flex duct runs through plaster chaseways that haven’t been opened since the 1980s retrofit. That local familiarity saves you time and prevents the trial-and-error approach that generalist HVAC crews bring from out of town.
Why Landmark Air Duct Cleaning Service New York Is Irvington’s Preferred Duct Repair & Sealing Company
Richard Anderson has spent two decades building this business around one thing: indoor air systems. Not generalist HVAC services — ductwork, period. When you call our number, you’re talking to the person who will actually show up at your Irvington door with a Rotobrush system and Nikro equipment, not a dispatcher sending an unknown subcontractor. That accountability matters in a village where every house presents a different retrofit puzzle.
Our reputation is verifiable: 548 customers have left reviews averaging 4.9 stars. That’s one of the highest review volumes in the duct cleaning trade, and it reflects consistent results across jobs exactly like yours — sagging flex duct in damp Irvington basements, failed mastic seals in tight attic cavities, mold sources hidden above finished ceilings. We’ve earned those ratings by solving problems that franchise crews walk away from.
Response time to Irvington is typically same-day or next-day. We’re based in New York City with direct routes up the Saw Mill River Parkway, and we don’t overbook. Richard Anderson handles your job personally — the person who built the business is the person doing the work. No rotating roster. No “we’ll send a guy.”
We also understand the local conditions that break ductwork in Irvington. The village’s immediate proximity to the Hudson River generates persistently elevated humidity compared to inland Westchester towns — river fog and moisture regularly penetrate older building envelopes. Combined with duct systems that were shoe-horned through plaster walls and unfinished crawl spaces during 1980s–90s retrofits, these conditions create failure modes that technicians from White Plains or Scarsdale simply haven’t encountered.
Our Duct Repair & Sealing Services in Irvington
Duct Sealing
In Irvington’s Victorian and Colonial Revival homes, duct sealing isn’t a matter of slapping tape on a joint. The original plaster walls and tight chaseways used for retrofit ductwork make traditional repairs ineffective — only foil-backed mastic and mechanical fasteners hold long-term against our humid riverfront climate. We seal supply and return plenums, register boots, and longitudinal seams using Abatement Technologies-compatible mastic compounds rated for the temperature swings these attic cavities see. A typical duct sealing job in Irvington runs $280–$480 for accessible systems, with costs rising if we need to open finished ceiling sections to reach failed joints.
Flex Duct Repair
This is where we spend most of our time in Irvington. Many Victorian and Craftsman homes converted from steam heat to forced-air HVAC during the 1980s–90s, resulting in flex duct runs through damp basement crawl spaces that sag and collect standing condensation — a major mold source unique to this retrofit-heavy riverfront village. Unsupported flex duct in these conditions traps water, restricts airflow, and eventually collapses entirely. We remove damaged runs, install properly supported R-8 insulated duct with mastic-sealed joints, and reconnect to your existing filtration system. Flex duct repair in Irvington typically costs $320–$580 depending on linear footage and access difficulty.
Metal Duct Repair
Some Irvington homes — particularly the sturdier Colonial Revivals on the higher hillside lots — have galvanized metal trunk lines from later retrofits. These corrode at seams and damper locations where decades of Hudson River moisture have collected. We patch small breaches with galvanized sheet and seal with high-temperature mastic; for larger failures, we fabricate replacement sections on-site. Metal duct repair in Irvington runs $380–$650, with most jobs falling in the $450 range for standard trunk line sections.
Duct Insulation
Unconditioned crawl spaces and basement ceiling cavities in Irvington’s pre-war homes create condensation problems that no amount of sealing alone can solve. We install R-8 fiberglass duct wrap or closed-cell foam insulation on exposed supply runs, particularly critical for ducts passing through the damp perimeter zones near foundation walls. Proper insulation prevents the temperature differential that causes moisture accumulation — stopping mold before it starts. Duct insulation in Irvington costs $4.50–$7.00 per linear foot, with minimum job sizes of roughly $350.

Trusted Brands We Service in Irvington
We work with the equipment that’s actually installed in Irvington homes. Richard Anderson carries parts and maintains familiarity with Honeywell, Aprilaire, and Guardsman air quality systems — the brands we encounter most frequently in Westchester County retrofits and upgrades. Our van stocks common Aprilaire filter housings, Honeywell media cabinet components, and Guardsman UV sanitizer bulbs, which means most Irvington customers don’t wait for a second visit. For the duct repair itself, we deploy Rotobrush and Nikro inspection and cleaning systems alongside Abatement Technologies-compatible sealants and adhesives — the same contractor-grade equipment most residential crews never carry. When we repaired that collapsed flex duct off Clinton Avenue, we had the Aprilaire reconnection fittings on hand. No delay. No return trip.
Common Duct Repair & Sealing Problems We See in Irvington Homes
- Collapsed flex duct above finished basements. On a recent job off Clinton Avenue, our crew found a collapsed section of flex duct hidden above a finished basement ceiling, choking airflow to the second floor. We removed the damaged run, installed properly supported R-8 insulated duct with mastic-sealed joints, and reconnected it to the homeowner’s Aprilaire filtration system — restoring full HVAC performance and eliminating the musty smell that had plagued the house for years.
- Unsupported flex duct in damp crawl spaces. Technicians working the lower, riverfront streets of Irvington frequently encounter flex duct that was hastily added during 1980s–90s retrofits inside Victorian-era homes, run without proper support through damp basement ceiling cavities. These sections sag, trap standing condensation, and are often the primary mold source that residents can smell but can’t locate.
- Failed mastic seals in tight attic cavities. Mastic seals on retrofitted duct joints in Irvington’s tight attic spaces fail due to temperature swings and moisture, creating invisible air leaks that waste energy and pull in fiberglass insulation particles. We find these by pressure-testing the system, then reseal with fresh foil-backed mastic rated for the application.
- Plaster wall chaseways that defeat tape repairs. Irvington’s original plaster walls and tight chaseways make traditional duct tape repairs ineffective within months. Only proper mechanical fastening and mastic application survive the humidity cycling that these riverfront homes experience.

FAQs — Duct Repair & Sealing in Irvington
The combination of 1980s–90s retrofit installation and Irvington’s elevated riverfront humidity is the culprit. Flex duct in these retrofits was often run without proper support through damp basement ceiling cavities, where it sags over time, creating low points where condensation pools instead of draining. Call (833) 754-6107 for a free inspection — we’ll show you exactly where the problem starts.
Yes — we access retrofitted ductwork through existing register openings, basement connections, and small strategic openings that we repair and match afterward. We don’t tear open plaster walls unless absolutely necessary, and we’ll tell you before that becomes the plan. Richard Anderson has navigated these chaseways in dozens of Irvington homes.
Very likely yes — standing condensation in sagging flex duct breeds mold that circulates throughout your home when the blower runs. We’ve traced this exact symptom to hidden duct failures in Irvington’s riverfront homes more times than we can count. A quick inspection with our Nikro camera system usually confirms the source within minutes.
Yes — we install R-8 fiberglass duct wrap or closed-cell foam on exposed supply runs in unconditioned spaces, which is critical for preventing the condensation that destroys ductwork in Irvington’s damp perimeter zones. Most insulation jobs run $350–$600 for typical residential systems.
Most repairs are completed in four to six hours, with larger flex duct replacements or multi-point sealing jobs extending to a full day.
