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 Hampton
If your HVAC system runs constantly but rooms near Bear Creek or along Highway 20 never reach temperature, your ducts are probably leaking conditioned air into your crawl space. Our Hampton Duct Sealing service typically costs between $400 and $1,200 for a whole-home seal, depending on how much of your system runs through that damp crawl space and whether we need to repair crushed or disconnected flex duct first. Our crews are dispatched from the Atlanta office and carry mastic sealant, metal-backed tape, and replacement flex duct on every truck serving Henry County. Call (361) 326-5060 and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Hampton’s Preferred Duct Sealing Company
We’ve been sealing ducts in Henry County long enough to know that Hampton isn’t Stockbridge, and our Hampton Dryer Vent Cleaning experience gives us the same crawl-space expertise. The crawl-space foundation culture here means we spend as much time on our knees in red clay as we do on the main floor. Roy Castellanos and our team have walked hundreds of these dirt-floor crawl spaces, and we’ve learned to spot the crushed flex duct, rodent-chewed runs, and rusted metal connections that slab-on-grade crews miss entirely.
Our customers in Hampton’s older neighborhoods near the original downtown and in subdivisions off McDonough Road tell us the same thing: other companies quoted a price over the phone, then tried to add charges once they saw the crawl space. That doesn’t happen here. We price in writing before we start, and that price is protected by our 365-Day Done Right Promise. If the seal 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. No voicemail loops, no waiting until Monday to schedule. Our background-checked, uniformed technicians arrive inside the quoted window, explain what they found, and leave the site clean. That’s The Garrison Standard, and it’s how we operate in every Hampton home.
Air Duct Sealing in Hampton
Air Duct Sealing in Hampton means closing the gaps, cracks, and disconnected joints in your duct system so the air you pay to heat or cool actually reaches your rooms instead of leaking into your crawl space or attic. Most Hampton homes need this because flex duct running through damp, unconditioned crawl spaces separates at the seams, gets chewed by rodents, or crushes under its own weight when the fiberglass support sags. A typical whole-home seal in Hampton runs $400 – $1,200; if we find extensive duct damage requiring section replacement, that can push toward $1,800 – $2,500. We always inspect first and give you a written price before sealing anything.
What We Seal
Our technicians seal supply and return plenums, trunk line connections, register boots, and every flex duct joint with mastic sealant or metal-backed tape rated for HVAC use. In Hampton crawl spaces, we commonly find the flex duct lying directly on damp dirt, which crimps airflow and accelerates deterioration. We suspend and seal it properly so it stays intact.
When Sealing Isn’t Enough
Sometimes the duct is too far gone. If we find flex duct that’s been chewed open by rodents or rotted through from condensation, we’ll show you the damage and quote replacement sections before proceeding. We don’t seal over duct that needs to be replaced; that’s not a fix, it’s a Band-Aid.
Duct Sealing Services in Hampton
Duct Sealing Services in Hampton from Hollis cover everything from minor leak repair to full-system mastic sealing after duct cleaning or replacement work. Because so many Hampton homes have original flex duct from the 1980s and 1990s, we regularly see systems that have never been sealed since installation. The tape originally used dries out and falls off; the fiberglass insulation gets wet from crawl-space humidity and collapses onto the duct. Our crew uses professional-grade equipment from Rotobrush and Nikro to clean debris first, then seals with mastic that flexes with temperature changes and won’t degrade in damp conditions.
Sealing After Cleaning
We often recommend pairing sealing with Air Duct Cleaning in Hampton because pulling debris out of the system first lets us see every leak clearly. Sealing dirty ducts traps contaminants inside; cleaning first, then sealing, gives you a system that’s both clean and tight. Ask about bundled pricing when you call.

Dryer Vent Safety Check
While we’re in your crawl space or utility room, we can also inspect your dryer vent run. Many Hampton homes have long, flex-vent dryer runs through the crawl space that sag and trap lint. We offer Dryer Vent Cleaning in Hampton as a separate service, and we’ll flag any safety concerns we spot during the duct sealing visit.

Trusted Brands We Service in Hampton
Our trucks carry sealing and filtration products from Honeywell, Aprilaire, and Guardsman, plus cleaning equipment from Rotobrush and Nikro. We don’t run to a supply house mid-job; the materials we need for Hampton’s common duct configurations are already on the truck. That means your job gets done in one visit, not two. If your system uses specialized components, we’ll tell you during the estimate call so there are no surprises. Every product we install is backed by manufacturer warranty plus our own 365-Day Done Right Promise.
Common Duct Sealing Problems We See in Hampton Homes
- Crushed flex duct on damp crawl-space floors. In Hampton’s pier-and-beam homes, flex duct often lies directly on red clay dirt that stays wet year-round. The weight of the insulation and any moisture saturation causes the duct to flatten, cutting airflow to rooms by 30% or more. We suspend, repair, and seal these runs so air moves freely again.
- Rodent damage at duct seams. Mice and rats enter crawl spaces through foundation vents and chew flex duct for nesting material. We find shredded fiberglass and gaping holes in ductwork near Lovejoy Road homes especially, where larger lots mean more wildlife pressure. We seal accessible entry points and replace chewed sections.
- Failed original tape at trunk connections. The cloth-backed tape used in 1980s and 1990s Hampton construction dries to dust after twenty years in crawl-space humidity. We remove the residue and seal with mastic, which bonds to metal and flex duct permanently even in damp conditions.
- Condensation rust on metal duct and fittings. North Georgia’s humid subtropical climate keeps Hampton crawl spaces damp much of the year. Metal plenums and register boots rust through at the seams, creating leaks that blow conditioned air into the crawl space instead of your bedroom. We seal what can be saved and replace what can’t.
Pricing for Duct Sealing in Hampton, GA
A typical whole-home duct sealing in Hampton runs $400 – $1,200. Small homes with straightforward trunk-and-branch systems near the downtown core usually fall at the lower end. Larger homes in subdivisions off McDonough Road with extensive crawl-space duct runs, multiple damage points, or rodent-chewed sections requiring replacement can reach $1,800 – $2,500. What drives cost: how much duct runs through crawl space versus attic, how accessible the connections are, whether we need to clean first to locate all leaks, and if sections need replacement rather than sealing.
We don’t quote per-vent or over the phone without seeing your system. Every estimate is free, written, and agreed to before work starts. The price doesn’t move at the door. Call (361) 326-5060 to schedule yours.

FAQs About Duct Sealing in Hampton
Whole-home duct sealing in Hampton typically costs $400 – $1,200, with larger or more damaged systems reaching $1,800 – $2,500 if section replacement is needed. We inspect first and give you a written price before any work begins. Call (361) 326-5060 for a free estimate.
Most Hampton jobs take 3 to 5 hours, depending on crawl-space access and how much of the system needs attention. Homes with extensive flex duct damage may need a second visit for replacement sections, but we’ll tell you that during the estimate, not halfway through the job.
Yes. We seal ducts throughout Hampton, from the older mill-village cottages near downtown to the subdivisions off McDonough Road and rural properties toward Lovejoy. Crawl-space access varies by foundation type, but we’ve worked on virtually every configuration common to Henry County.
Not because of location, but because of foundation type. Hampton’s high percentage of crawl-space homes means we often find more damage to repair than in slab-on-grade markets like parts of Stockbridge. The sealing work itself is priced the same; the difference is whether we need to replace crushed or rodent-damaged duct first.
If any sealed joint fails, any mastic cracks, or any replaced section leaks within one year of our visit, Hollis returns and makes it right at no charge, including a free second visit. It’s in writing on every job, not a verbal assurance. Call (361) 326-5060 if you ever need us back.
