Fast, Reliable Duct Repair & Sealing Across Beverly
Duct repair and sealing in Beverly, MA typically costs $180–$650 depending on accessibility and material type, with most jobs completed in a single visit. For homes in Beverly’s historic districts, where retrofit ductwork winds through 19th-century framing and coastal moisture attacks seams year-round, proper sealing isn’t a luxury—it’s what keeps your heating bills from bleeding through gaps you can’t see.
We’re Titan Air Duct Cleaning Lowell, and we make the drive down Route 1A or across the Newburyport Turnpike to Beverly regularly. Thomas Hernandez, our owner and lead technician, has spent 14 years crawling through duct systems in North Shore homes exactly like yours. From Peach’s Point ranches to the Victorian multi-families near Washington Street, we’ve traced airflow problems through chases that out-of-area crews didn’t know existed. When you call (877) 517-5646, you’re getting Thomas on the phone and Thomas at your door—not a dispatcher sending subcontractors.
Why Titan Air Duct Cleaning Lowell Is Beverly’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has built a reputation in Beverly one job at a time. We’ve worked in basements along Margin Street where salt air from Salem Sound had eaten through galvanized seams, and in crawlspaces off Beverly Center Business District where 1980s flex duct had turned to powder. That consistency shows in our numbers: 389 verified reviews averaging 4.7 stars, with Beverly customers specifically noting that we found leaks their previous company missed.
Response time matters when your furnace is cycling constantly or a bedroom stays ten degrees colder than the rest of the house. We’re typically in Beverly within one to two business days, sometimes same-day for urgent airflow failures. More importantly, we arrive prepared for what Beverly throws at us—custom mastic formulations for moisture-wicking brick foundations, extension rigs for 12-foot plaster ceilings, and the patience to work around historic fabric that can’t be replaced.
Thomas shows up as the owner and the technician doing the work. That means 14 years of specialized air duct and HVAC system experience applied directly to your home, with no information lost between salesperson and crew. Professional-grade equipment built for more than a basic residential clean—Rotobrush, Nikro, and Abatement Technologies platforms—lets us handle remediation-grade access problems in ordinary houses.
Our Duct Repair & Sealing Services in Beverly
Duct Sealing
Sealing is where we start most Beverly jobs, because leakage is the silent killer of efficiency and air quality. In homes near Atlantic Avenue and the waterfront, we regularly measure 25–35% airflow loss at joints before we touch a tool. Our sealing protocol combines mechanical fastening with mastic sealant rated for coastal humidity, applied to both accessible and limited-access duct runs. For Beverly’s historic homes with ducts routed through original masonry chases, we fabricate custom mastic beads that compensate for irregular gaps—standard tape or caulk won’t bond to moisture-wicking brick, and we’ve learned that the hard way so you don’t have to.
Flex Duct Repair
Flex duct installed during 1970s and 1980s retrofits is reaching end-of-life across Beverly’s older neighborhoods. The plastic liner becomes brittle, the fiberglass insulation compresses, and the wire helix corrodes—especially in crawlspaces and knee-walls where coastal humidity concentrates. On Charter Street in the historic district, our crew repaired a flex-duct that had pulled away from a supply register in a 12-foot plaster ceiling. We used a Rotobrush scrub and mastic sealant to reconnect the duct, preventing costly plaster demolition. When flex duct is too far gone, we replace with new insulated flex or convert to rigid metal where access allows.
Metal Duct Repair
Galvanized sheet metal in Beverly faces an enemy inland towns don’t: salt-laden marine air from Salem Sound accelerates corrosion at seams and joints, with visible failure often appearing within 5–7 years of installation in waterfront homes. We repair separated seams with proper mechanical fastening followed by high-build mastic, not tape that will peel. For corroded sections, we fabricate replacement duct from matching gauge metal or install spiral duct where space permits. In Victorian multi-families near Fish Flake Hill, we’ve restored airflow to entire wings by repairing metal ducts hidden behind knee-wall bulkheads that original steam-pipe chases made nearly inaccessible.
Duct Insulation
Uninsulated or degraded duct insulation in Beverly’s unconditioned spaces creates condensation, mold, and thermal loss. We see this constantly in homes where retrofit ducts were routed through exterior walls or vented attics. Our insulation work uses closed-cell or foil-faced products appropriate for the moisture load, sealed at all seams to prevent the “sweating” that breeds microbial growth. For homes in Peach’s Point with more standard 1970s–1990s construction, insulation upgrades often pair with sealing to solve both efficiency and humidity problems in one pass.
Mastic Sealant Application
Mastic is our preferred sealant for Beverly’s challenging substrates, but application technique matters enormously. On historic brick foundation penetrations in Fish Flake Hill, we’ve learned that standard mastic fails to bond due to moisture wicking through the masonry. We use specialized formulations and surface prep—wire brushing, drying passes, sometimes primer—to achieve adhesion that lasts. This isn’t guesswork; it’s what 14 years of North Shore ductwork teaches you. The mastic we apply with Nikro application rigs cures to a flexible, durable seal that moves with thermal expansion without cracking.

Trusted Brands We Service in Beverly
We don’t show up hoping your system matches what we carry. Our trucks stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies—brands we’ve selected for performance in coastal New England conditions. Honeywell airflow sensors and Aprilaire humidity controls integrate with sealed duct systems to maintain the balance Beverly’s climate demands. For sealing and repair, we source mastic and reinforcement fabrics rated for marine humidity exposure, not the hardware-store grade that fails in two seasons. That means faster turnaround for Beverly customers: most repairs don’t wait for parts orders.
Common Duct Repair & Sealing Problems We See in Beverly Homes
- Corroded galvanized seams on waterfront properties. Salt-laden marine air from Salem Sound attacks duct joints along Atlantic Avenue and the harbor side, causing leakage that homeowners mistake for “old house drafts.” We test with calibrated pressure diagnostics to pinpoint corrosion failures invisible to casual inspection.
- Retrofit duct separations behind knee-wall bulkheads. In Victorian multi-families near Fish Flake Hill and Charter Street, ducts hidden in original steam-pipe chases pull apart from thermal cycling and vibration. The separation is unseen but shows up as rooms that never reach set temperature despite a running furnace.
- Failed mastic on moisture-wicking brick foundations. Improper mastic application on historic basement penetrations looks sealed but leaks persist. We’ve re-treated dozens of Beverly foundations where previous work skipped surface prep, bonding to dust instead of masonry.
- Undersized flex duct from 1970s–80s retrofits. Beverly’s older homes converted from radiator heat often received ductwork too small for modern furnace airflow. The system runs loud, heats unevenly, and burns out blower motors. We resize and seal for proper static pressure.
Pricing for Duct Repair & Sealing in Beverly, MA
| Service | Typical Range in Beverly |
|---|---|
| Duct sealing (accessible, single zone) | $180–$340 |
| Duct sealing (whole-house, limited access) | $450–$850 |
| Flex duct repair/replacement (per run) | $220–$480 |

| Mastic sealant application (historic foundation) | $280–$520 |
| Duct insulation (per linear foot) | $8–$14 |
What moves you within these ranges? Access difficulty is the big variable. A duct run in an open basement costs less than the same repair behind a 12-foot plaster ceiling or buried in a tight knee-wall. Material type matters too—metal fabrication takes longer than flex replacement but lasts decades longer in Beverly’s coastal environment. We don’t quote over vague descriptions; we inspect, measure pressure loss, and give you a written estimate before work starts. Call (877) 517-5646 to schedule—estimates are free, and we’re straightforward about whether repair or replacement makes sense for your specific situation.

FAQs — Duct Repair & Sealing in Beverly
Salt-laden marine air from Salem Sound accelerates galvanized steel corrosion, with waterfront Beverly homes showing seam failure in 5–7 years versus 12–15 years in inland Danvers. The difference is measurable in our pressure diagnostics—Beverly joints simply leak sooner. If you’re near Atlantic Avenue or the harbor, we inspect for corrosion even on relatively young ductwork. Call (877) 517-5646 for a leak test.
Yes, in most cases we access and seal ducts through existing registers, basement connections, or small strategic cuts in less visible locations. On Charter Street, we reconnected a separated flex-duct through the register opening using extended mastic application tools, avoiding any plaster demolition. We treat historic fabric as non-replaceable and plan access accordingly. Call (877) 517-5646 to discuss your specific layout.
Persistent symptoms reveal hidden problems: rooms that won’t heat evenly, furnace cycling more than three times per hour, dust accumulation near registers, or utility bills rising without rate changes. We use pressure pan testing and infrared imaging to locate leaks in concealed duct runs common in Beverly’s retrofitted homes. The diagnostics take about 45 minutes and tell us exactly what’s hidden. Call (877) 517-5646 to schedule testing.
We specify mastic formulations from Abatement Technologies and application systems from Nikro for Beverly’s humidity and salt exposure, avoiding standard tapes and caulks that degrade in marine conditions. Aprilaire humidity controls pair well with sealed systems to manage the moisture that would otherwise attack new seals. These aren’t marketing names—they’re what we’ve validated through 14 years of North Shore callbacks, or rather, the lack of them. Call (877) 517-5646 to discuss material specifications for your job.
Separated flex duct or failed connections at supply registers, caused by decades of thermal cycling in tight chases originally built for steam pipes. The duct pulls away, airflow drops, and homeowners compensate by cranking the thermostat. We find and repair these separations with minimal intrusion, often restoring comfort to rooms that have been cold for years. Call (877) 517-5646—estimates are free.
