Wherever you are in 94568, we show up on time, in uniform, with a camera to show you what’s actually happening inside your walls.
Why Bellows Air Duct & Vent Co. Is Dublin’s Preferred Duct Repair & Sealing Company
Forty-two years in business means we’ve seen every shortcut builders take. In Dublin, the biggest one is this: those large two-story production homes in East Dublin were thrown up fast during the housing boom, with long multi-branch duct runs and builder-grade air handlers that start failing right when homeowners stop thinking about them. We don’t just patch the symptom. We find the leak, show you the camera footage, and seal it so it stays sealed.
Our customers in Dublin call us back because we answer the phone. Live person, 24 hours a day. No app. No voicemail maze. Our Duct Repair & Sealing in Dublin crews are background-checked and uniformed, and every job carries our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing. That’s been our way since 1984.
We’re also straightforward about price. Before we lift a single tool, you’ll know exactly what the repair costs. The number on the phone is the number on the invoice. No bait coupons, no scare tactics, no surprises when we’re already in your attic.
Our Duct Repair & Sealing Services in Dublin
Duct Sealing
Most Dublin homes we visit are leaking 20-30% of their conditioned air into attics and crawl spaces. In East Dublin’s two-story tract homes, the problem is worse - long duct runs with multiple joints that loosen from vibration and temperature swings. We seal every accessible joint with professional-grade materials, then verify with camera inspection. A typical duct sealing job in Dublin runs $280-$550 for a standard single-system home.
Flex Duct Repair
Flex duct is the weak link in most Dublin attics. The original builder-grade flex in Jordan Ranch and Fallon Village homes has often sagged, torn at connections, or pulled loose entirely. We replace damaged sections with new insulated flex, secure them with metal collars, and seal with mastic. Flex duct repair in Dublin typically costs $180-$340 per section, depending on accessibility and length.
Metal Duct Repair
The older ranch homes in West Dublin sometimes have galvanized metal ductwork from the 1960s and 70s. It rusts. It separates at seams. We’ve resealed metal trunk lines in homes off San Ramon Road and replaced rusted sections that were blowing conditioned air into crawl spaces. Metal duct repair in Dublin runs $220-$480, with full section replacement at the higher end.
Duct Insulation
Dublin’s inland location means attic temperatures swing hard - 140°F in summer, below freezing in winter. Uninsulated or degraded duct insulation wastes energy year-round. We install fresh fiberglass or foil-faced insulation to R-6 or R-8, depending on your system. Duct insulation work in Dublin typically ranges $350-$650 for a complete system.
Mastic Sealant
We use mastic on every Dublin job where it matters. Unlike tape, which dries and fails, mastic remains flexible and bonds permanently to metal, flex, and fiberglass. In Dublin’s dry climate, tape failure is accelerated - we’ve peeled off ten-year-old foil tape that turned to dust. Mastic is the standard we apply, and it’s included in our sealing work at no extra charge.
Air Leak Repair
Return air leaks are especially common in Dublin’s larger homes, where builders used wall cavities and chases as ductwork. These leaks pull attic dust and wildfire smoke directly into your living space. We identify and seal these pathways, often finding gaps at platform returns and filter racks that have been wasting energy since the home was built.

Trusted Brands We Service in Dublin
We carry parts and materials from Rotobrush, Abatement Technologies, and Aprilaire - the same brands serious HVAC contractors specify for their own homes. For Dublin customers, this means we don’t wait on shipping for common repairs. We stock mastic, metal collars, insulated flex, and replacement registers so most jobs finish the same day we start. If your system uses specialized components, our Cleveland office coordinates overnight parts so we’re not making you wait.
Common Duct Repair & Sealing Problems We See in Dublin Homes
- Builder-grade flex duct loosens at joints. In East Dublin’s tract homes, vibration from air handlers and temperature cycling cause connections to separate. We find gaps at air handler connections and Y-junctions that have been leaking for years.
- Original construction dust never got purged. Homes in Jordan Ranch and Fallon Village were occupied with drywall dust still in the ducts. That dust grinds against seals, accelerates wear, and keeps blowing even after “cleaning” if the source isn’t sealed.
- Wildfire smoke infiltrates through leaks. Dublin’s smoke-trapping geography means fine particulates enter duct systems through every gap. Sealing is the only way to stop recontamination after fire season.
- Long duct runs create pressure imbalances. Those sprawling two-story floor plans push air handlers to their limits. We balance and seal to get conditioned air to the rooms that need it.

FAQs - Duct Repair & Sealing in Dublin
Your ducts likely still contain original construction drywall dust that was never purged before move-in, and that dust keeps migrating through leaks in builder-grade flex duct. Cleaning alone won’t stop it if the duct connections are loose and the dust source is still active. We seal the leaks and remove the residual contamination so the problem actually stops. Call (844) 685-6342 for a camera inspection - estimates are free.
Altamont Pass winds carry fine dry-soil particulate from the Central Valley into Dublin’s inland basin, creating a heavier dust load than coastal Bay Area cities experience. This particulate infiltrates through every duct leak and gap, accelerating seal deterioration and contaminating your air handler. Sealing your duct system is the only way to stop this infiltration at its entry points.
Yes - it’s one of our most frequent calls from those communities. The original flex duct in homes built from the late 1990s through the 2010s is now 15-25 years old, and the vibration and temperature cycling in Dublin’s climate have loosened connections and caused sagging. We recently sealed a leaky flex duct junction in a 2004-built home off Fallon Road in the Fallon Village area, where the builder had left a gap at the air handler connection. Using mastic sealant and new metal collars, we stopped the conditioned-air loss and cut the homeowner’s energy waste - a repair that had been causing uneven cooling in their upstairs bedrooms for years.
Sealing prevents smoke particulates from re-entering, but it won’t remove existing contamination already inside your ducts. We typically recommend sealing first to stop infiltration, then targeted cleaning for residual odor. In Dublin’s smoke-trapping geography, this two-step approach is the most reliable way to keep your indoor air clean through fire season. Call (844) 685-6342 and we’ll assess whether sealing, cleaning, or both makes sense for your system.
Mastic is a thick, flexible paste that bonds permanently to metal, flex, and fiberglass duct surfaces, creating an airtight seal that lasts decades. We use it instead of foil tape because Dublin’s dry, hot-summer climate destroys tape adhesive within a few years - we’ve peeled off failed tape that turned to powder. Mastic stays flexible and sealed, which is why it’s the standard we apply on every job.
