Why Bellows Air Duct & Vent Co. Is Gresham Park’s Preferred Duct Repair & Sealing Company
We’ve worked in Gresham Park long enough to know which crawl spaces have 18 inches of clearance and which require us to send our slimmest technician with a headlamp. That matters when you’re repairing ductwork you can’t see from the hallway. Our crews understand the specific failure patterns of 1950s-1970s ranch homes here - the original fiberglass duct board that delaminates in humidity, the 1980s flex upgrades that sag and kink, the metal trunks coated in DeKalb County’s distinctive red-clay dust.
Ray Castillo, who leads Bellows, started this company in 1984 on the principle that a homeowner should see the problem before paying to fix it. Every Gresham Park job still gets a camera inspection before and after. Our 90-Day Done Right Promise means if a seal fails or a repair doesn’t hold, we return at no charge - no paperwork, no arguing. Calls to our office reach a live person 24 hours a day, not a voicemail tree. And our pricing? Disclosed before we lift a single tool. The number we give on the phone is the number on the invoice.
We’re not the cheapest outfit advertising a $49 coupon. We’re the company you call when you’ve already tried that and had to call someone else to fix it.
Our Duct Repair & Sealing Services in Gresham Park
Duct Sealing
Gresham Park’s original metal trunk-and-branch systems were built with tape and hope - standards that failed decades ago. We seal leaking joints and seams with mastic sealant rated for Georgia’s humidity cycles, applied after thorough cleaning. In older Gresham Park crawl spaces, we regularly find that red-clay dust has embedded in old mastic, so we remove the contaminated layer entirely before resealing. A typical duct sealing job for a 1,500-square-foot Gresham Park ranch runs $340-$580, depending on access and contamination level.
Flex Duct Repair
The flex duct installed during 1980s and 1990s HVAC upgrades in Gresham Park has now had 30-40 years to sag, kink, and pool condensation under crawl spaces. We recently sealed a 1960s metal trunk in a Gresham Park brick ranch off Flat Shoals Road, where sagging 1980s flex duct in the crawl space had kinked and pooled condensation, while the original main trunk was coated with red-clay dust blown in from foundation vents - two distinct contamination layers we cleaned and sealed with mastic. Where the flex is salvageable, we rehang, repair, and seal. Where it’s collapsed or mold-compromised, we replace the run. Flex duct repair in Gresham Park typically costs $180-$340 per run; full replacement runs $280-$520.
Metal Duct Repair
The original galvanized steel trunks in Gresham Park’s mid-century ranches are structurally sound but chronically leaky at seams and takeoffs. We repair separated joints, patch corrosion holes, and reseal connections - always after camera verification. Metal duct repair here demands extra prep because of that red-clay infiltration; we use Rotobrush contact cleaning and Nikro HEPA vacuums to prepare surfaces before mastic application. Typical metal duct repair in Gresham Park ranges from $260-$480 for localized work, or $580-$940 for full trunk resealing.
Duct Insulation
Crawl-space duct runs in Gresham Park lose massive efficiency through uninsulated or degraded insulation. We replace waterlogged or pest-damaged insulation with closed-cell foam or foil-faced fiberglass appropriate for Georgia’s humidity. Insulation replacement for a typical Gresham Park ranch system runs $420-$780.

Trusted Brands We Service in Gresham Park
Our Gresham Park crews work with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify when they’re doing their own homes. We stock mastic sealants, flex duct, and insulation materials sized for the 1950s-1970s systems common here, which means most repairs don’t wait on parts. That matters when your crawl space is 95 degrees and your system is blowing attic air into your bedroom.
Common Duct Repair & Sealing Problems We See in Gresham Park Homes
- Original fiberglass duct board liners delaminate in high humidity. Gresham Park’s persistently humid crawl spaces accelerate the breakdown of 1960s-era duct board, causing the interior liner to shed particles into airflow. Once delamination begins, sealing is no longer viable - the board requires full replacement.
- Sagged or kinked flex duct from 1980s-90s upgrades accumulates condensation and debris. Under low Gresham Park crawl spaces, poorly supported flex duct pools water and restricts airflow. The kinks also trap debris, creating a compounding problem that reduces system efficiency by 30% or more before homeowners notice.
- Red-clay dust infiltration through foundation vents coats metal ducts. DeKalb County’s heavy red-clay soil blows into crawl spaces and embeds in old mastic and duct interiors. This contamination must be removed before new sealing adheres properly - a step discount operators often skip.
- Humidity-driven mold colonization in unsealed joints. Atlanta’s muggy summers create condensation at every leaky duct seam in Gresham Park’s unconditioned crawl spaces. Over years, this moisture breeds mold that spreads through the system and degrades indoor air quality.

FAQs - Duct Repair & Sealing in Gresham Park
Once the interior fiberglass liner starts delaminating, sealing won’t hold and the board needs replacement. We verify this with camera inspection; if the liner is intact but joints are leaking, we can seal. If it’s shedding particles, we quote replacement. Call (844) 685-6342 for a free camera inspection - we’ll show you exactly what you’re dealing with.
DeKalb County’s heavy red-clay soil blows through foundation vents and settles on every surface in your crawl space, including duct interiors. This is nearly universal in Gresham Park’s older homes with vented crawl spaces and slab-adjacent grading. We remove this contamination with contact brushing and HEPA vacuuming before any sealing work. The dust won’t stop coming, but proper filtration and sealed ductwork keep it out of your living space.
Sometimes. If the flex is intact but poorly supported, we rehang it with proper strapping and seal the connections. If it has collapsed, kinked beyond airflow recovery, or grown mold from pooled condensation, replacement is the only lasting fix. We camera-inspect to determine which approach applies before we quote. Most flex duct repairs or replacements in Gresham Park are completed in a single visit.
Metal ducts in Gresham Park’s unconditioned crawl spaces experience extreme temperature swings and persistent moisture, which degrades old tape adhesives and causes thermal expansion that reopens sealed joints. Newer homes often have conditioned crawl spaces or flex-duct systems with fewer seams. We use mastic rated for Georgia’s humidity cycles and always clean contaminated surfaces first - a preparation step that’s more critical here than in drier climates or newer construction.
Yes, our Gresham Park crews use Rotobrush contact cleaning systems as part of surface preparation before sealing metal ducts. We also use Nikro HEPA vacuums and Abatement Technologies containment equipment. The right tool for the right surface - we don’t default to one method for every job. Call (844) 685-6342 and we’ll explain what your specific system needs.
