Fast, Reliable Duct Repair & Sealing Across Pinewood
Duct repair and sealing in Pinewood typically runs $180-$650 depending on whether we’re reconnecting a single flex run or resealing an entire metal trunk system, and most jobs are completed in one visit. If your vents are blowing weak, your AC runs nonstop, or you’ve noticed a musty smell when the system kicks on, the culprit is often ductwork that’s pulled apart in your attic or rusted through at the joints.
We’ve been driving to Pinewood since 1984, and we know the 33167 ZIP well. The post-war CBS ranches along NW 22nd Avenue and the streets off the Turnpike are built on the same slab-and-block pattern, with unconditioned attics that turn into ovens from May through October. That heat destroys flex duct. We’ve replaced collapsed runs in homes near Pinewood Park and sealed rusted metal trunks in the neighborhoods between NW 103rd Street and the Palmetto. Our technicians are background-checked, uniformed, and carry the equipment to fix most problems the same day. Call (844) 685-6342 and you’ll reach a live person, 24 hours a day. We’ll give you an upfront price before we start, and we back every job with our 90-Day Done Right Promise in writing.
Why Bellows Air Duct & Vent Co. Is Pinewood’s Preferred Duct Repair & Sealing Company
Homeowners in Pinewood call us because we’ve earned a reputation for showing up when we say and leaving the job finished. Our reviews from Pinewood customers mention the same things repeatedly: we explain what’s wrong before we fix it, we show camera footage of the damage, and the price on the phone matches the price on the invoice. We’re not the cheapest outfit advertising a $49 coupon, and we don’t want to be. We’re the company you call when you’ve already been burned by a bait-and-switch operator who changed the price at the door.
Our response time to Pinewood is typically same-day or next-day. We stock insulated flex duct, mastic sealant, and sheet-metal fittings on every truck, so we’re not driving back to a warehouse while your attic sits open. Every technician answers to our office in Los Angeles, where a live person picks up the phone around the clock. That’s been our practice for over 42 years.
Ray Castillo, who leads Bellows, started this company on a simple standard: one honest price, shown before we start, and we stand behind it with no paperwork and no arguing. That standard hasn’t changed.
Our Duct Repair & Sealing Services in Pinewood
Flex Duct Repair
Flex duct is the black, ribbed tubing you’ll find in most Pinewood attics, and it’s the first thing to fail in our climate. The 140°F attic temperatures in summer soften the wire helix inside, causing the duct to sag between joists. Over time, the sagging creates low points where condensation pools, and the weight pulls the duct free from the plenum or the register boot. We’ve found completely detached flex runs in Pinewood homes that have been pulling unfiltered attic air, loaded with insulation fibers and mold spores, directly into bedrooms for months or years. Our Duct Repair & Sealing team replaces the damaged sections with properly supported, insulated flex duct rated for Miami-Dade’s conditions. We strap it every four feet and seal every joint with mastic, not tape that will dry out in two summers.
Duct Sealing
Even ducts that look intact can leak 20-30% of your conditioned air into the attic. In Pinewood’s older CBS homes, the original mastic sealant has been through thousands of thermal cycles, heating to 140°F by day and cooling to 70°F at night. That expansion and contraction cracks the seal. We pressurize the system and use a smoke pencil or theatrical fog to find every leak, then reseal with fresh mastic applied to clean, dry metal. For homes with extensive leakage, we may recommend Aeroseal, a polymer that seals from the inside. The result is cooler rooms, lower electric bills, and an AC system that doesn’t run itself to death.
Metal Duct Repair
The original galvanized steel trunk lines in Pinewood’s 1950s-1970s ranches weren’t built for decades of condensation. Rust eats through the metal at low points and at the plenum connection, creating gaps that blow cooled air straight into the attic. We cut out the rotted sections and splice in new galvanized pipe, or we transition to insulated flex duct where the geometry allows. Every repair is camera-inspected before we close up, so you see the work, not just hear about it.
Duct Insulation
Uninsulated or poorly insulated duct in a Pinewood attic is a double waste: you’re paying to cool air that gains 10-15 degrees before it reaches your vents, and the cold metal surface sweats, dripping condensation onto your ceiling drywall. We wrap repaired or replaced duct with R-6 or R-8 fiberglass insulation with a reinforced vapor barrier, sealed at every seam. In homes near the Turnpike where pollen and diesel particulates are already elevated, keeping ductwork sealed and insulated is a real defense for your indoor air quality.

Common Duct Repair & Sealing Problems We See in Pinewood Homes
- Flex duct disconnected from the plenum in unconditioned attics. The constant heat cycling in Pinewood’s 140°F attics causes the plastic collar on flex duct to harden and crack. Once the seal breaks, the duct pulls in unfiltered attic air laden with insulation fibers, rodent dander, and mold spores from the humid attic deck. We see this failure mode worsen every summer, and it’s frequently the hidden cause of persistent respiratory complaints in households that have already replaced their AC unit.
- Original metal trunk lines rust through at low points after decades of condensation. The galvanized steel in Pinewood’s post-war CBS homes wasn’t designed for 50-plus years of Miami-Dade humidity. Rust holes at the plenum or sag points blow 20-30% of cooled air into the attic, and the homeowner only notices when the electric bill climbs or the back bedrooms won’t cool below 78°F.
- Mastic sealant on aged connections cracks from thermal cycling. Every summer day, Pinewood attic ductwork goes from 75°F at dawn to 140°F by mid-afternoon. That daily expansion and contraction turns flexible mastic brittle within five to seven years. Reapplication during every major repair is necessary to maintain an airtight seal, not an upsell.
- Collapsed flex duct in rental properties with no maintenance history. Many homes in 33167 have passed through multiple owners or long-term rental arrangements with no record of duct inspection. We find flex duct that has been crushed by storage items, chewed by rodents, or simply collapsed under its own weight after the internal wire support corroded through.

FAQs - Duct Repair & Sealing in Pinewood
Yes. In Pinewood’s unconditioned attics, heat-softened flex duct commonly pulls free from the plenum, drawing in humid attic air loaded with mold spores and organic debris. That musty smell is often the first sign. We camera-inspect the connection, reattach or replace the damaged flex, and seal with mastic. Call (844) 685-6342 for a free inspection.
Minor repairs like flex duct replacement and mastic resealing typically do not require a permit in unincorporated Miami-Dade County, where Pinewood sits. If we’re modifying the main trunk line or altering the system’s CFM capacity, we pull the proper permit and coordinate inspection. We handle the paperwork when it’s needed. Call (844) 685-6342 and we’ll tell you whether your specific job requires a permit.
Yes. Sealed ductwork prevents your system from pulling in unfiltered attic air and outdoor pollutants, including the elevated particulate load near the Turnpike corridor. We pair duct sealing with an Aprilaire media filter to capture pollen, diesel particulates, and mold spores. Many Pinewood homeowners with allergies notice reduced symptoms within 48 hours of sealing. Call (844) 685-6342 for an estimate.
We can seal intact metal duct with fresh mastic at all joints and seams. If the metal has rusted through at low points or the plenum, we cut out the damaged section and splice in new material or transition to insulated flex duct. We camera-inspect before we recommend either approach, so you’re not paying for replacement where sealing will suffice. Call (844) 685-6342 for a free second opinion on any written estimate.
Most single-story ranch jobs in Pinewood take three to five hours. A simple flex duct repair might run two hours; a full system resealing with multiple repairs takes closer to six. We complete most jobs in one visit, and we don’t leave until the camera confirms the work. Call (844) 685-6342 to schedule.
On SW 112th Avenue, we sealed a 1962 ranch home where the original metal trunk line had rusted through at the plenum, and two flex runs had disconnected-pulling in attic insulation fibers. We replaced the failed sections with insulated flex duct, applied mastic sealant at all joints, and installed an Aprilaire media filter to protect the system. The owner reported that the persistent musty odor in the kids’ bedrooms vanished by the next morning.
