Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Duct Sealing Across East Point
We dispatch our Duct Sealing crews to East Point from our Atlanta office, and we know the neighborhoods from Conley Hills down to Jefferson Park. Most East Point calls we answer the same day, and we schedule sealing work within a few days, not weeks. If your registers blow dust every time the AC cycles, or your upstairs rooms never cool evenly, the problem is usually leaky ductwork, not the unit itself. Call us at (361) 326-5060 and we’ll walk through what we find and what it costs before we schedule anything.
Why Hollis Air Duct Cleaning Is East Point’s Preferred Duct Sealing Company
We’ve been working in East Point long enough to recognize the patterns. The post-WWII brick bungalows off Washington Road and the ranches near the MARTA line have ductwork that predates most of the technicians who installed it. Our crews arrive uniformed, background-checked, and on time, because The Garrison Standard doesn’t allow anything less. We write the price down before we touch a tool, and that number doesn’t move at the door. Every sealing job carries our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting through a voicemail loop when you’ve got a question about your appointment.
Duct Sealing Services in East Point
Duct Sealing Services in East Point address a specific problem: conditioned air escaping through gaps, disconnected collars, and deteriorated seams before it ever reaches your rooms. In this market, a typical whole-house duct sealing job runs $1,200 – $2,800 depending on accessibility, the extent of leakage measured during our pre-test, and whether we need to seal metal trunk lines, flex branches, or both. We use mastic sealant and metal-backed tape rated for HVAC applications, not the hardware-store foil tape that peels off in Atlanta’s humidity. Every job starts with a written price and ends with a post-test showing the reduction in leakage.
Leak Detection and Sealing
We pressurize your duct system and measure actual leakage in CFM, then mark every gap with a camera so you see what we see. On East Point’s older galvanized systems, we often find slip joints that have opened from decades of thermal cycling, plus flex branches that have pulled free at the collar. We seal what can be sealed and flag what needs replacement.

Register and Boot Sealing
The connection between your duct boot and the floor or ceiling is a common leak point, especially in homes where settling has opened gaps. We seal these with mastic and proper backing, then verify with a smoke pencil that air isn’t bypassing into the wall cavity.

Duct Insulation in East Point
Duct Insulation in East Point is often the missing piece after sealing is complete. Uninsulated or poorly insulated ducts in attics and crawl spaces lose 20 – 30% of their conditioned air to the surrounding space, which means you’re paying to cool your attic in July. In East Point, where summer humidity hangs above 70% for months, condensation on cold duct surfaces also feeds biological growth. A typical duct insulation job here runs $800 – $1,800 for wrapping accessible trunk lines and branches with formaldehyde-free fiberglass or closed-cell foam, depending on linear footage and access difficulty.
Attic Duct Wrapping
We wrap sealed metal ducts with insulation rated to R-6 or higher, secured with proper mechanical fasteners so it doesn’t sag in the heat. This is standard on East Point ranches with attic-mounted air handlers, where the trunk line runs the length of the house before dropping to the rooms below.
Crawl Space Duct Protection
Insulation in damp crawl spaces needs a vapor barrier jacket to prevent moisture from degrading the material. We use products from Guardsman and Abatement Technologies that hold up in the conditions we find beneath East Point’s older homes.
Trusted Brands We Service in East Point
Our trucks stock sealing mastics, mechanical fasteners, and insulation from Guardsman and Abatement Technologies, plus rotary brush systems from Rotobrush for the agitation work that precedes sealing on heavily contaminated ducts. We don’t have to order parts and make you wait. For filtration upgrades after sealing, we carry Aprilaire media cabinets and replacement filters sized to the systems common in East Point’s post-war housing stock. If your home needs a component we don’t have on the van, our Atlanta office sources it next-day.
Common Duct Sealing Problems We See in East Point Homes
- Original galvanized trunk seams weeping air. Decades of thermal cycling have widened every slip joint in these 1940s-1960s systems. Sealing without source removal first just traps airport grit against the metal, so we clean before we seal.
- Crushed or disconnected flex branches behind kitchens and baths. The undersized early flex duct common in East Point ranches collapses or pulls off its collar, so the run reads as sealed at the boot but dumps conditioned air into the wall cavity. We find these with camera inspection.
- Condensation in unsealed returns near the airport corridor. Summer humidity condenses inside leaky return plenums, feeding biological growth that re-contaminates the duct the moment the blower cycles back on. Sealing stops the moisture intrusion.
- Black soot-like staining around supply vents. Our crews regularly find this pattern in airport-adjacent homes, a mix of jet exhaust residue and brake dust that migrates through every gap in the ductwork. Proper sealing with filtration upgrades keeps it out of the living space.
Pricing for Duct Sealing in East Point, GA
A typical duct sealing job in East Point runs $1,200 – $2,800 for the full system, based on what we find during our pre-test. Smaller partial-system repairs, like sealing a disconnected branch or reattaching a few registers, can run $400 – $800. Duct insulation added after sealing typically adds $800 – $1,800. What moves the number: the linear footage of ductwork, whether it’s accessible from the attic or crawl space, the condition of existing materials, and whether we need to bring in negative-air HEPA filtration to clean before sealing. We test, we show you the leakage numbers, we write the price down, and that price is what you pay. No per-vent gimmicks, no coupon that doubles once we’re inside.

FAQs About Duct Sealing in East Point
East Point sits directly beneath Hartsfield-Jackson’s flight paths, so ducts here accumulate a fine grayish film that tests with jet-exhaust and brake-dust signatures alongside typical pollen. That grit migrates into every gap and joint, accelerating seal deterioration and making leakage more severe than in cities just a few miles away. We prep and seal differently here because the contamination profile is genuinely unusual. Call (361) 326-5060 and we’ll explain what we found in homes near yours.
Most original galvanized trunk lines in East Point’s 1940s-1960s housing can be sealed if the metal is intact and not rusted through. We camera-inspect first. If the seams have opened from thermal cycling but the metal is sound, mastic sealing restores performance. We flag replacement needs before any work starts, and we write the price for either option so you decide. Call (361) 326-5060 to schedule an inspection.
We start with a pressure test to measure total leakage, then run a camera through the supply and return ducts to mark every gap. On a typical East Point ranch, we find opened slip joints on the galvanized trunk, disconnected flex branches, and gaps at the register boots. We clean with negative-air HEPA filtration and rotary brush agitation if needed, then seal with mastic and metal-backed tape. A post-test confirms the reduction. The whole job usually takes a day. Call (361) 326-5060 for a free estimate.
Yes, sealing reduces infiltration by 15 – 30% on average, which means less outdoor pollen, jet exhaust particulates, and road dust entering through leaks in the return side. In East Point, where the airport corridor adds a unique particulate load, that reduction is noticeable. We often pair sealing with a filtration upgrade from Aprilaire for homes where occupants are sensitive. Call (361) 326-5060 to discuss options.
Leaking ducts show uneven temperatures between rooms, whistling at registers, dust streaks on ceiling grids, and utility bills that climb without explanation. Dirty ducts blow visible debris and may smell musty. Many East Point homes have both problems, and the airport-adjacent grit makes the dirty-duct symptoms more pronounced. Our pressure test and camera inspection separate the two issues and show you exactly what needs addressing. Call (361) 326-5060 to book a diagnostic.
