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.

AfterFast, Reliable Duct Sealing Across Canton
We seal ductwork in Canton homes from the mill-era cottages near downtown to the newer subdivisions off Riverstone Parkway and Sixes Road. Our crews are scheduled through our Atlanta office and carry the tools to handle both hard-piped trunk systems and long flex runs buried in blown-in insulation. If your registers push weak air, your upstairs rooms never cool evenly, or you’ve noticed yellow-green pollen dust collecting on grilles after spring, the problem is often leaky ducts, not your air handler. Call us at (361) 326-5060 for a free estimate. We’ll price the work in writing before we start, and every sealed system is covered by our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Canton’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In Canton, that means something. We’ve worked on the short, galvanized trunk-and-branch systems in the older neighborhoods off East Main Street and the multi-system homes near Hickory Flat where three separate air handlers serve a single house. Roy Castellanos leads our operation, and The Garrison Standard governs every job: arrive inside the window, price in writing, work by the book, leave the site clean.
Our technicians are background-checked and uniformed. You know who is walking into your home before they arrive. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues. No waiting until Monday when your upstairs bedroom is 12 degrees hotter than the thermostat reading.
We don’t compete on teaser coupons. We compete on discipline. The price we write down before any work starts is the price you pay. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan. It’s in writing on every job.
HVAC Duct Sealing in Canton
HVAC Duct Sealing in Canton addresses a problem most homeowners don’t know they have: conditioned air leaking into attics, crawl spaces, and wall cavities before it ever reaches the rooms you paid to heat or cool. In our market, a typical whole-system seal runs $800 – $1,800 for a single air handler, depending on access, duct material, and how many joints need treatment. Homes with multiple systems, which we see frequently in newer Canton subdivisions, are priced per system so you’re not paying for work you don’t need or skipping systems that still leak.
Our process starts with a camera inspection of the full duct run. We identify crushed boots, separated joints, and failed tape. Then we seal with mastic and fiberglass mesh, the standard for permanent joints, or replace damaged flex runs where sagging has created low points that trap moisture and pollen.
Per-System Pricing for Multi-System Homes
Many Canton homes built after 2005 have two or three separate HVAC systems. Sealing only one leaves the others leaking, creating pressure imbalances that pull humid attic air into the living space. We price each system separately, and we seal only the ones you authorize. No package deals that force work you don’t want.
Camera Documentation You Can Keep
We photograph every joint before and after sealing. You get the images. This matters for work you cannot see inside finished walls and attics. It’s how we prove the job happened, and it’s how we verify our own work under the 365-Day Done Right Promise.
Duct Repair in Canton
Duct Repair in Canton often starts with a call about weak airflow or a room that never reaches temperature. The real cause is frequently a crushed flex run, a disconnected boot, or old cloth-backed tape that has dried and turned to dust. Repair costs in our market typically run $300 – $900 for isolated fixes, and $1,200 – $2,500 when we’re replacing multiple damaged runs or rebuilding a section of hard-pipe trunk. We write the price before we touch anything.
Our crews carry Rotobrush rotary systems and Nikro negative-air machines, but for duct repair the critical tools are support straps, mastic, mesh, and the right diameter flex to match your existing system. We don’t use duct tape. The cloth-backed stuff failed once already. The silver HVAC tape is a temporary patch at best. Permanent repair means mastic, mechanical support, and proper slope so condensate drains.
Mill-Era Hard-Pipe Restoration
The galvanized steel trunk-and-branch systems in Canton’s older homes near downtown were built to last, but the original tape and gasket material hasn’t. We remove failed sealing material entirely before resealing. Covering old tape with new mastic traps moisture against the joint and guarantees failure within a season.
Flex Run Replacement in Newer Homes
Long flex runs in unconditioned attics sag when they’re not strapped every four feet. The low point collects condensation, pollen, and dust. We replace the damaged section, add proper support, and seal the connections with mastic. Sealing alone without addressing the sag just traps the debris inside.
Trusted Brands We Service in Canton
We stock parts and filtration products from Aprilaire, Abatement Technologies, and Guardsman for Canton jobs. That means faster turnaround when your system needs a component we don’t carry on the van. We also use Rotobrush rotary brush systems for pre-sealing cleaning when ducts are loaded with debris, and Nikro negative-air equipment for containment during repair work. These are the same tools commercial crews use, not hardware-store gear, and we explain what each one does while we’re in your home so you understand why we’re using it.
Common Duct Sealing Problems We See in Canton Homes
- Failed cloth tape on mill-era hard-pipe joints. The original tape in downtown Canton homes has dried and let go after decades in hot attics. We see this on almost every pre-1980 system we inspect. The fix is complete removal and resealing with mastic and mesh, not another layer of tape.
- Crushed branch boots in older systems. Short hard-pipe runs off the main trunk were often installed with tight clearances. Over years of attic traffic or insulation work, the boot deforms and leaks. Camera inspection finds it; mastic and mechanical repair fix it.
- Unsupported flex runs in newer subdivisions. Long flex buried under blown-in insulation in Canton homes near Bridgemill and Creekstone sags between joists. Condensation and pollen-laden dust collect at the low point. Sealing the boot without strapping the run traps the problem inside.
- Partial sealing of multi-system homes. We regularly find Canton homes with three systems where a previous company sealed only the easiest one. The homeowner still gets uneven temperatures and high humidity because the unsealed systems pull attic air through leaks. We price and document every system separately so you know exactly what was done.
Pricing for Duct Sealing in Canton, GA
A single-system duct sealing in Canton typically runs $800 – $1,800. Duct repair for isolated damage runs $300 – $900. Whole-home multi-system work on three separate air handlers ranges $2,200 – $4,800. These are honest ranges for our market, not teaser prices that jump once we’re inside.
What moves the price: access (crawl space vs. walk-in attic), duct material (hard-pipe vs. flex), number of joints needing treatment, and whether we need to clean debris before sealing. We inspect with a camera, write the full price before any work starts, and that’s what you pay. No per-vent pricing. No add-ons at the door. Call (361) 326-5060 for a free estimate.

FAQs About Duct Sealing in Canton
We seal whichever systems you authorize, priced per system. Sealing only one in a multi-system Canton home often leaves pressure imbalances that pull humid attic air through the remaining leaks. We camera-inspect all three, document what we find, and let you decide which to address. Call (361) 326-5060 for an exact quote on each system.
Canton’s humid subtropical climate and high spring pollen from oak, pine, and grass create ideal conditions for microbial growth inside ducts. When leaks pull warm, moist attic air into cool ductwork, condensation forms. Pollen enters through the same leaks and sticks to the wet surface. Sealing the ducts stops both the moisture source and the pollen infiltration.
Yes. We photograph every joint before and after sealing, and we pressure-test the system to verify reduced leakage. You receive the images and test results in writing. This documentation is also how we verify our work if you need to invoke the 365-Day Done Right Promise.
Mill-era homes near downtown Canton use short, hard-piped trunk-and-branch systems with galvanized steel. The original cloth-backed tape has usually failed. Newer subdivisions use long flex runs with multiple air handlers. The sealing method differs: mastic and mesh for hard-pipe, proper support and slope correction for flex. We assess which era your home represents before quoting.
It will reduce the pollen and dust entering through duct leaks, which is a significant source. If your ducts are also loaded with accumulated debris, we may recommend cleaning with our Rotobrush system before sealing. Sealing clean ducts gives the best result. Call (361) 326-5060 and we’ll inspect to determine what your specific system needs.
A homeowner off East Main Street near downtown Canton called us because their upstairs registers were pushing weak, musty air even after a spring pollen season that left visible yellow-green dust on the grilles. Camera inspection showed a crushed hard-pipe branch boot off the main trunk leaking into the attic – a classic mill-era layout. We sealed the joints with mastic and mesh, reconnected the boot, and verified with a blower-door-assisted leak check that the supply static pressure dropped and every upstairs register was reading normal airflow again.
