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 Loganville
Most Loganville homeowners lose 20 – 30% of their conditioned air through leaky ductwork before it ever reaches the rooms they’re paying to cool. In a market where new two-story homes near Sharon Elementary and older ranches off Highway 78 sit side by side, that waste shows up fast on summer power bills that already spike from May through September. We’re the Duct Sealing in Loganville crew that shows up in uniform, prices the job in writing before touching anything, and seals it by the book. Dispatch and scheduling run through our Atlanta office, but our technicians live and work this corridor daily. Call (361) 326-5060 for a free estimate. We’ll quote you a flat price per system, not a per-vent shell game.

We know Loganville’s housing stock because we’ve worked it: the 1970s metal duct systems with corroded joints off Cooper Road, the flex runs in unconditioned attics above newer subdivisions near Bay Creek Park, the red clay dust that bakes into every surface it touches. That local knowledge changes how we approach the seal.
Air Duct Sealing in Loganville
Air Duct Sealing in Loganville starts with understanding what kind of debris is already inside your ducts. In this market, that’s often not just household dust. Loganville’s new-construction boom means many homes are sealed before the first AC season, so the builder’s flex duct in the unconditioned attic is already coated in drywall and red clay dust that gets baked into sticky residue once the system runs through a Georgia Piedmont summer. A sealing job here often starts as remediation, not maintenance. The price for a typical residential system in Loganville runs $850 – $1,800 depending on duct accessibility, the extent of leakage found during pressure testing, and whether source removal of construction debris is needed first.
Pressure Testing Before Sealing
We pressurize your duct system and measure leakage at the air handler, joints, and register boots. A typical Loganville home loses 20 – 30% through these gaps. We show you the number before we seal it. No guessing.
Mastic and Mesh Application
We seal accessible joints with duct mastic reinforced with fiberglass mesh, not tape that cooks off in a 130°F attic. In Loganville’s unconditioned attics, tape fails in one season. Mastic doesn’t.
Duct Sealing Services in Loganville
Duct Sealing Services in Loganville cover the full system: supply and return trunks, flex duct connections, register boots, and the air handler cabinet where factory seals often leak from day one. We were called to a new two-story in the Sharon Elementary area where the homeowner noticed reddish dust at the registers within months of moving in. Our tech ran a camera inspection, found the flex runs in the attic packed with drywall dust and clay from the nearby grading, and used agitation tools with HEPA filtration before applying mastic and mesh to the leaky joints. After sealing and negative pressure source removal, the supply and return ducts held pressure and the film stopped returning. Typical pricing for this level of work in Loganville falls between $1,200 – $2,400 for whole-system sealing with pre-cleaning.
Air Handler Cabinet Sealing
Poor factory sealing lets clay dust bypass the filter and coat the blower motor. We seal the cabinet itself, not just the ducts attached to it. This is where most crews stop short.

Post-Seal Verification
We test again after sealing. The pressure reading proves the work. You get the before and after numbers in writing, plus photos from the camera inspection.

The tools are professional-grade, not hardware-store gear, and we explain what each one does while it’s running in your attic.
Common Duct Sealing Problems We See in Loganville Homes
- Sealing over construction debris without source removal. Drywall dust and red clay bake onto duct walls and clog the seal, so the leak returns by the first summer. We see this in new builds off Cooper Road where the builder’s crew sealed the ducts before the drywall crew finished sanding.
- Tape or short-lived sealant on flex duct in 130°F+ attics. The adhesive fails in one season and joints open again. Loganville’s unconditioned attics hit these temperatures reliably from June through August.
- Ignoring the air handler and blower motor cabinet. Poor factory sealing lets clay dust bypass the filter and coat the motor, reducing airflow and eventually burning out the component. We seal the cabinet as part of every job.
- Flex duct crushed by installers in tight attic spaces. Common in newer two-story homes where truss design leaves minimal clearance. Crushed flex restricts airflow and creates turbulence that pulls attic air through adjacent leaks.
Pricing for Duct Sealing in Loganville, GA
A typical duct sealing job in Loganville runs $850 – $1,800 for accessible systems with moderate leakage. Jobs requiring construction-debris source removal first, or systems with extensive flex replacement in tight attics, range $1,200 – $2,400. We price by the system, not by the vent. One flat price agreed before work starts. No per-vent add-ons. No ballooning at the door.
What moves the number: attic accessibility (crawl vs. walk-in), the extent of leakage measured during pressure testing, whether source removal is needed before sealing, and the condition of existing flex duct. We inspect first, quote in writing, then you decide. Estimates are free. Call (361) 326-5060.

FAQs About Duct Sealing in Loganville
Builder-grade flex duct in unconditioned attics is often installed with minimal sealing, and the drywall dust and red clay from construction bake into sticky residue during the first Georgia Piedmont summer. That debris clogs attempts to seal over it, so the leak returns. We remove the source first, then seal properly. Call (361) 326-5060 for an inspection and written quote.
It’s Piedmont red clay that dries, flakes, and gets drawn into your return ducts when the AC cycles. After heavy rain, the mud around new construction sites dries to fine dust that standard vacuums won’t remove without agitation. We see this pattern consistently in Loganville’s newer subdivisions. The fix is source removal with rotary brush agitation and HEPA filtration, followed by proper sealing of the return path.
Original metal duct systems with corroded joints can often be sealed successfully if the metal itself is intact. We pressure-test first. If leakage is at joints and boots, sealing with mastic and mesh is cost-effective. If the trunk is rusted through or collapsed, replacement makes more sense. We’ll show you the camera footage and give you both options in writing.
Sealed returns don’t pull attic air, so pine and oak pollen stays outside the system. Sealed supplies deliver full airflow to each room, reducing the humidity differential that causes condensation in duct walls. In Loganville’s climate, that condensation mixes with clay dust to create the sticky residue we find coating flex runs. Proper sealing breaks that cycle.
Yes. We seal the air handler cabinet as part of every job. Poor factory sealing lets clay dust bypass the filter and coat the blower motor, reducing efficiency and shortening motor life. We inspect, photo-document, and seal these gaps. The blower motor and cabinet are included in our flat system price, not billed as an add-on.
