Why Bellows Air Duct & Vent Co. Is Andover’s Preferred Duct Repair & Sealing Company
We’ve been in Andover homes long enough to recognize the telltale musty smell of saturated duct board before we even open the attic hatch.

Homeowners in neighborhoods near the intersection of NW 27th Avenue and Stirling Road regularly refer us to neighbors after seeing our camera-inspected before-and-after footage.
Our response time to Andover averages under two hours during business hours, and our phones are answered by a live person 24 hours a day, not an app or voicemail maze. That matters when your AC is blowing warm and the humidity inside your house is climbing toward 80%.
We carry a strong local reputation built on never needing to be called back. Our 90-Day Done Right Promise is stamped on every job in writing. If it’s not right, we make it right. No paperwork, no arguing. That’s how we’ve operated since 1984.

Our Duct Repair & Sealing Services in Andover
Duct Sealing
Leaky ducts in Andover homes waste 20-30% of cooled air into attics and crawlspaces, which is money you’re paying FPL to throw away. In the 33023 ZIP, we find that original duct runs in CBS homes built before 1985 often have gaps at plenum connections and failed tape seams from decades of thermal cycling. Our duct sealing service uses professional-grade mastic sealant applied to every joint and penetration, then pressure-tested to verify results. Camera documentation before and after every job means you see the improvement, not just take our word for it.
Flex Duct Repair
Flex duct in Andover’s humidity deteriorates faster than in drier climates. The plastic inner liner becomes brittle, the insulation wrapping compresses, and the outer vapor barrier cracks, exposing the fiberglass to moisture. We repair flex duct with matching material rated for South Florida’s conditions, or replace sections that have gone too soft to hold shape. At a 1968 CBS home on NW 27th Avenue, we found the original fiberglass duct board had delaminated from 30+ years of daily condensation. Rather than patch a deteriorating system, we recommended full replacement with sealed metal ducts and mastic joints to match the home’s long AC season. That’s the kind of honest assessment you get from a company that plans to be here another 42 years.
Metal Duct Repair
Galvanized metal ducts in older Andover homes corrode at seams and joints where condensation pools. We cut out damaged sections, fabricate replacement pieces on-site, and seal with mastic, not tape. Metal duct repair in Andover runs $340-$680 depending on accessibility and extent of corrosion. Every repair is pressure-tested and camera-verified before we leave.
Duct Insulation
Re-insulating ducts after repair is non-negotiable in Andover. Exposed metal in a 130-degree attic without proper insulation sweats immediately, and that condensation becomes water damage, mold, and structural rot. We use foil-faced fiberglass insulation with proper vapor barriers, installed to Florida Energy Code standards. This step is where discount operators often cut corners, and it’s why we get called back to fix their work.
Mastic Sealant
Mastic sealant is the only permanent solution for Andover’s humidity. Duct tape, even the foil-backed variety, fails within months when subjected to South Florida’s daily condensation cycles. We apply Abatement Technologies professional-grade mastic to every seam, joint, and penetration, then brush-seal for complete coverage. The result is a duct system that stays sealed through years of thermal expansion and contraction. Mastic sealant application as part of a larger repair runs $180-$320 in Andover.

Common Duct Repair & Sealing Problems We See in Andover Homes
- Assuming moldy duct board can simply be cleaned. In Andover’s 33023 corridor, original fiberglass duct board from pre-1980s CBS homes is often so saturated and friable from decades of humid-air cycling that it cannot be cleaned - only replaced - making duct material inspection a mandatory first step for any Duct Repair & Sealing job. Quoting only a cleaning without checking material condition is a common callback problem here.
- Sealing leaks with tape alone on aged flex duct. In Andover’s humidity, tape fails within months as adhesive breaks down and backing separates. Mastic sealant is required for a lasting fix, applied over fiberglass mesh for structural reinforcement at joints.
- Ignoring the need to re-insulate ducts after repair. Condensation forms on exposed metal in crawlspaces and attics, causing water damage to ceilings, mold in insulation, and eventual structural rot. We reinsulate every repaired section as standard practice.
- Overlooking material compatibility with South Florida’s AC runtime. Andover homes run cooling effectively 11-12 months per year. Repair materials rated for seasonal use in northern climates fail prematurely here. We specify components rated for continuous operation in high-humidity environments.

FAQs - Duct Repair & Sealing in Andover
No, not if the duct board has become saturated and friable, which we find in most pre-1985 Andover homes. In the 33023 corridor, decades of daily condensation have turned original fiberglass duct board into a mold substrate that releases fibers and recolonizes within months of cleaning. We inspect material condition with a camera first. If the board is delaminated, we recommend replacement with sealed metal ducts and mastic joints. Call (844) 685-6342 for a free inspection - estimates are free, and we’ll show you exactly what we’re seeing.
Every two to three years for homes with original ductwork, annually if you’ve had previous mold issues. Andover’s average relative humidity stays above 70% most of the year, and daily AC cycling creates condensation inside ducts that accelerates material degradation. Our $89 Seasonal Tune-Up includes a camera inspection of accessible ductwork to catch problems before they require major repair. Call (844) 685-6342 to schedule.
Yes, by a wide margin. Mastic sealant remains flexible and bonded through thousands of thermal cycles, while tape adhesive breaks down in Andover’s humidity within months. We apply Abatement Technologies professional-grade mastic over fiberglass mesh at every joint, then brush-seal for complete coverage. The difference in longevity is measured in years, not seasons. For a free assessment of your current duct sealing, call (844) 685-6342.
Yes, if the surrounding flex duct is still structurally sound. We cut out the damaged section and splice in matching material with proper supports and mastic-sealed connections. However, if the tear is one of several failures in aged flex duct, or if the insulation is compressed and the vapor barrier is cracked throughout the run, section repair becomes false economy. We’ll show you the camera footage and give you both options with upfront pricing. Call (844) 685-6342 for a free estimate.
Yes, always. Exposed metal duct in an Andover attic without insulation sweats immediately in our humidity, creating the exact moisture problems that caused the original damage. We reinsulate every repaired section with foil-faced fiberglass and proper vapor barriers to Florida Energy Code standards. This is included in our repair pricing, not sold as an add-on. Call (844) 685-6342 for a free estimate with no surprises on the bill.
