Call (844) 685-6342 - a live person answers, 24 hours a day.
We’ve been driving to Scituate since 1984, and we know the difference between a routine duct sealing call and the post-storm damage that hits homes near the Harbor, Minot Beach, and along Turner Road. Salt air, coastal humidity, and repeated flooding create failure modes here that inland HVAC crews simply don’t encounter. That’s why our Duct Repair & Sealing team carries marine-grade mastic sealant, insulated flex duct rated for damp crawl spaces, and the camera equipment to show you exactly what’s happening inside your trunk lines before we quote a price.
Why Bellows Air Duct & Vent Co. Is Scituate’s Preferred Duct Repair & Sealing Company
Our reputation in Scituate was built on showing up after the 2018 nor’easters when other companies were still clearing their backlogs. Homeowners on the coast needed someone who understood salt-flooded ductwork, not a generic duct cleaning franchise. We replaced corroded metal trunks, pulled silt-packed flex duct from crawl spaces, and sealed systems back to tight operation - and we put it all on camera so the homeowner could see the before and after.
We answer calls with a live person, day or night. No app. No voicemail maze. When a Scituate homeowner smells mold after a storm surge or notices their second floor isn’t getting airflow, they want to talk to someone who knows Turner Road from First Parish Road, not a call center in another state. Our background-checked, uniformed technicians are dispatched from our local operation and carry the parts to complete most repairs in one trip.
Every job comes with our 90-Day Done Right Promise in writing. If the seal doesn’t hold, if a joint we masticed starts leaking, or if the new flex duct settles wrong, we return at no charge. No paperwork to file. No argument. We stand behind it because we’ve stood behind our work for over 42 years.
Our Duct Repair & Sealing Services in Scituate
Duct Sealing
Scituate homes lose 20-30% of conditioned air through leaky joints, on average. In coastal neighborhoods where salt corrosion has eaten at metal duct seams, that number climbs higher. We seal every accessible joint with mastic sealant - not tape, which dries and fails - and we camera-verify the seal before we leave. A typical whole-system sealing in Scituate runs $450-$750 for an average single-family home.
Flex Duct Repair
Flex duct is the weak link in most Scituate crawl spaces. After the 2018 nor’easters, our crew was called to a home on Turner Road near Minot Beach, where salt floodwater had entered the crawlspace, soaking the flex duct insulation and corroding the metal supply trunk. We replaced the flex runs with new insulated duct, cleaned the metal sections with a Rotobrush, and applied mastic sealant to all joints, restoring the system to tight operation. Flex duct replacement in Scituate typically costs $180-$340 per run, depending on length and access.
Metal Duct Repair
Original galvanized steel trunks in Scituate’s 1950s and 1960s beach cottages weren’t designed for decades of salt-laden air. We see pinhole corrosion at joints, separated seams, and rusted hangers that let the trunk sag. Our metal duct repair includes cutting out corroded sections, fabricating replacement pieces, and sealing with mastic. Most metal repairs in Scituate fall between $320-$580.
Duct Insulation
Uninsulated or water-damaged duct insulation in Scituate crawl spaces wastes energy and creates condensation that feeds mold. We install fresh fiberglass or closed-cell insulation around repaired and sealed ducts, with vapor barriers where coastal humidity demands it. Duct insulation work in Scituate generally runs $380-$620 depending on linear footage and accessibility.

Trusted Brands We Service in Scituate
We carry parts and materials from Abatement Technologies, Rotobrush, and Aprilaire - the same brands serious HVAC contractors specify for coastal environments. For Scituate homeowners, that means no waiting on special orders when your flex duct is mold-saturated after a storm. Our trucks stock insulated flex, marine-grade mastic, and corrosion-resistant hardware so we can complete most repairs in that first visit. We don’t believe in bait pricing or showing up to “assess” before revealing the real cost. The number we quote on the phone is the number on the invoice.
Common Duct Repair & Sealing Problems We See in Scituate Homes
- Corroded metal duct joints from salt-laden coastal air. Massachusetts Bay exposure accelerates interior corrosion at seams and joints, causing air leaks that pull humid outside air into the system and reduce efficiency by 15-25%.
- Flood-damaged flex duct in low-lying neighborhoods near the Harbor. After nor’easters, we find flex duct packed with tidal silt and active mold - a failure mode almost unheard of in Norwell or Hanover but common enough here that post-storm duct inspections are part of Scituate’s seasonal home-recovery cycle.
- Undersized retrofitted duct runs in converted beach cottages. Many Scituate homes started as seasonal cottages with minimal ductwork, then had systems cobbled together for year-round use. The runs are too small, poorly sealed, and routed through uninsulated crawl spaces where they lose heat before it reaches the living space.
- Disintegrated original duct liner in older Cape Cod and colonial homes. The fibrous interior lining breaks down after 40-60 years, sending particles into the air and creating rough surfaces that trap moisture and mold spores.
Pricing for Duct Repair & Sealing in Scituate, MA
We’re straightforward about what duct repair costs in this market. A typical flex duct replacement in Scituate runs $180-$340 per run. Metal trunk repair or section replacement: $320-$580. Whole-system mastic sealing for an average 1,800-square-foot home: $450-$750. Duct insulation replacement: $380-$620.

What moves the price: how many runs need attention, whether we’re working in a dry basement or a damp crawl space near Minot Beach, and whether storm damage has compromised multiple components at once.

FAQs - Duct Repair & Sealing in Scituate
Salt-laden air from Massachusetts Bay accelerates corrosion inside metal duct joints and promotes mold growth on flex duct liners and insulation, typically causing leaks and efficiency loss 2-3 times faster than in inland towns like Hanover. We address this with marine-grade mastic sealant, corrosion-resistant hardware, and camera-verified inspection of every joint we touch. Call (844) 685-6342 if you smell musty air or notice uneven heating - we’ll show you exactly what’s happening inside your system.
Turn off your HVAC system immediately to prevent circulating contaminated air, then call us for a camera inspection - we need to see whether floodwater reached the ductwork before determining if cleaning, repair, or replacement is required. After the repeated nor’easters of 2018, we found duct systems in Scituate’s coastal neighborhoods packed with tidal silt and active mold, requiring flex duct replacement and metal trunk cleaning with Rotobrush equipment. Do not restart your system until a professional has assessed the damage. Call (844) 685-6342 for same-day emergency inspection.
Most duct repair and sealing work in Scituate does not require a permit if it involves existing ductwork within the conditioned envelope, but replacement of metal trunk lines or modifications to supply/return routing may trigger building department review under the Massachusetts State Building Code. We handle permit research as part of our upfront assessment and will tell you before work begins if your specific job requires town approval. Call (844) 685-6342 and we’ll verify permit requirements for your address during your free estimate.
Yes - Scituate’s housing stock is heavily weighted toward mid-20th century beach cottages converted to year-round use, with retrofitted duct runs that are undersized, poorly sealed, and routed through uninsulated crawl spaces close to grade, plus original Cape Cod and colonial homes with ductwork that has never been professionally cleaned or sealed. These conditions compound with coastal salt air to create leaks, mold, and efficiency problems rarely seen in newer construction. We specialize in bringing these older systems up to tight operation without tearing out walls. Call (844) 685-6342 for a camera inspection and honest assessment.
Light surface rust can be cleaned and sealed with mastic if the metal retains structural integrity, but pinhole corrosion or flaking metal requires section replacement - we camera-inspect to determine which condition we’re dealing with before quoting any work. In Scituate, we regularly see both scenarios, and we won’t charge you for sealing if the metal is too far gone to hold a seal. Our 90-Day Done Right Promise covers either approach. Call (844) 685-6342 for an exact diagnosis - estimates are free.
