Our Duct Repair & Sealing Services in Arlington
Duct Sealing with Mastic Sealant
Arlington’s original sheet-metal duct systems, many still in service from the coal-furnace era, have rough, corroded surfaces that modern duct tape cannot grip. We use professional-grade mastic sealant, applied by hand and reinforced with mesh where needed, to create a permanent bond on those old trunks. In the 02474 and 02476 ZIP codes, we’ve found that mastic is the only material that survives the temperature swings in uninsulated basements and crawl spaces. A typical mastic sealing job for a single-family Arlington home runs $280-$450, depending on linear footage and accessibility.

Metal Duct Repair
The large-diameter galvanized steel trunks in Arlington’s older homes weren’t designed for forced-air pressure. After 60-80 years of layered coal soot, conversion debris, and corrosion, they develop pinholes, separated seams, and collapsed sections. We cut out damaged portions, fabricate replacement sections to match the original dimensions, and integrate them with the existing system using proper transitions. On a two-family Colonial Revival along Massachusetts Avenue, we found the upstairs unit’s return plenum cut directly into the original coal furnace casing, with decades of soot and debris compromising airflow. Our crew sealed the juncture with mastic, repaired a corroded section of the old metal trunk, and insulated the exposed run in the basement to prevent condensation, restoring proper pressure and eliminating the musty smell that had plagued the tenants. Metal duct repair in Arlington typically costs $340-$620.

Flex Duct Repair
When central A/C was retrofitted into Arlington’s older homes, contractors often ran flexible duct through spaces never intended for it, sharp bends and compression points that fail prematurely. We replace crushed or torn flex duct with properly sized runs, support it to prevent sagging, and seal all connections with mastic, not zip ties and hope. Flex duct repair in Arlington generally runs $180-$320 per run.

Duct Insulation
Arlington sits in the Mystic River watershed, and the low-lying eastern sections of town, particularly in 02476 near Alewife Brook, experience elevated ambient humidity that accelerates condensation inside poorly insulated duct runs during summer shoulder months. This creates recurring mold conditions in basement and crawl-space sections that go unnoticed until air quality complaints arise. We insulate exposed metal and flex duct with formaldehyde-free fiberglass wrap or closed-cell foam board, depending on clearance and application. Proper insulation also prevents the thermal losses that make your system work harder than it should. Duct insulation in Arlington typically runs $220-$480, with crawl-space work at the higher end due to access difficulty.

Trusted Brands We Service in Arlington
We repair and seal ductwork connected to equipment from every major manufacturer, and we stock sealants and repair materials from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify. For Arlington’s older homes with non-standard configurations, having the right materials on the truck means we don’t waste your time with return trips. Our technicians carry flexible-shaft cameras, mastic in multiple formulations for different temperatures and surfaces, and insulation rated for the damp conditions common near Alewife Brook. When we say we’ll complete the job in one visit, we mean it because we’ve prepared for what Arlington’s housing stock actually requires.
Common Duct Repair & Sealing Problems We See in Arlington Homes
- Failed duct tape on coal-era metal. Previous handymen or discount services used modern duct tape or non-mastic sealants on rough, corroded surfaces. It fails within months due to temperature swings in uninsulated basements. We remove the old residue and apply mastic properly.
- Hidden return plenum leaks. The primary leak point in many Arlington two-families is the return plenum cut into the old coal furnace casing, invisible to anyone who doesn’t know to look for it. Sealing visible joints while ignoring this leaves the system wasting energy and circulating decades-old debris.
- Incomplete sealing in tight clearances. Arlington’s plaster-and-lath framing and narrow crawl spaces under double-deckers make some duct runs nearly inaccessible. Less-experienced technicians declare them “sealed” without actually reaching the joints. Our flexible-shaft equipment and patient approach get to what others miss.
- Condensation and mold in humid zones. The low-lying areas near Alewife Brook in 02476 see basement humidity levels that promote mold growth on uninsulated duct surfaces. Sealing alone won’t solve this; insulation and proper vapor barriers are required.

FAQs - Duct Repair & Sealing in Arlington
Because the previous sealing likely missed the primary leak point. In Arlington’s converted coal-furnace homes, the return plenum is often cut directly into the original gravity-furnace casing, a connection point that standard duct sealing ignores. That coal-era trunk has never been properly cleaned or sealed, and it’s drawing unconditioned air from your basement or crawl space, forcing your system to run longer. We camera-inspect the entire system, identify these hidden junctions, and seal them with mastic. Call (844) 685-6342 for a free second opinion on any previous work.
Yes, and we do it regularly. Arlington’s double-deckers on tight lots have crawl spaces that challenge larger technicians and rigid equipment. Our crew uses flexible-shaft cameras and application tools designed for exactly these conditions. We’ve sealed ducts in spaces where the clearance is less than 18 inches. The work takes longer, but it’s doable, and we price it upfront so you know before we start.
We don’t just seal; we insulate. The elevated humidity in 02476 near Alewife Brook causes condensation on cold metal duct surfaces, which promotes mold and eventually corrodes the metal. Our approach is sealing the joints with mastic, then insulating the exposed runs with vapor-barrier-wrapped fiberglass or closed-cell foam to raise the surface temperature above the dew point. This solves the moisture problem, not just the air leak.
Mastic sealant, applied generously and reinforced with fiberglass mesh, is the only reliable method. The rough, corroded surface of a century-old coal furnace casing won’t accept tape or standard sealants. We clean the surface as thoroughly as possible, apply mastic in multiple coats if needed, and bridge any gaps with mesh to prevent cracking. This is specialized work that requires knowing what you’re looking at, which is why we camera-inspect before we begin.
It will help significantly if the smell is caused by unsealed return ducts drawing air through a contaminated coal-era plenum. In Arlington’s two-family conversions, this is a common source of musty odors. Sealing the junction between old and new ductwork prevents your system from circulating basement air and decades of accumulated debris. If mold is present on the duct surfaces, we may also recommend sanitizing and insulation. Call (844) 685-6342 and we’ll diagnose the source before recommending any work.
