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 Edgewater
Your upstairs bedroom stays ten degrees warmer than the living room. Your energy bill climbed again this summer even though you haven’t touched the thermostat. In Edgewater, where humid air off the South River pushes through every crack and gap, these aren’t mysteries. They’re symptoms of leaky ductwork, and they’re fixable.
We seal ducts for homeowners from the older ranches along the Rhode River to the subdivisions off Route 2. Our crews dispatch from our Baltimore office and work Edgewater regularly, so we know which homes built in the 1960s and 70s still run original sheet-metal trunk lines with failing tape joints, and which newer builds have flex duct that’s pulled loose in the crawlspace. When you call (361) 326-5060, a live person answers, and we’ll get you a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Edgewater’s Preferred Duct Sealing Company
We’ve been at this since 2004, and our Edgewater customers tend to find us the same way: their neighbor had us out, or their HVAC tech spotted a duct problem and told them to call someone who wouldn’t just slap on more tape and disappear. Roy Castellanos runs our operation under The Garrison Standard, which means written prices, written guarantees, and no moving targets.
Our technicians are background-checked and uniformed. You get their name before they arrive. They show up inside the quoted window, price the job in writing, and leave the site clean. Every duct sealing job carries our 365-Day Done Right Promise: if the seal fails or the problem returns within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal assurance. It’s on the paperwork.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your ducts are dumping conditioned air into the crawlspace.
HVAC Duct Sealing in Edgewater
HVAC Duct Sealing in Edgewater addresses the gaps, disconnected joints, and deteriorated mastic that let heated and cooled air escape before it reaches your rooms. In a typical Edgewater home, especially the older waterfront ranches near the South River with original metal ductwork, we find 20-30% air loss through leaks in attics, crawlspaces, and behind walls. That means your system runs longer, wears faster, and costs more every month.
A standard duct sealing job in Edgewater runs $850 – $1,800 for most single-family homes, depending on system size, accessibility, and whether we’re sealing accessible joints or need to address buried trunk lines. We use professional-grade mastic compounds and metal-backed tape, not the hardware-store foil tape that peels off in Edgewater’s humidity within two seasons.
Sealing After Storm Damage
In Edgewater’s low-lying waterfront neighborhoods, we’ve found duct systems that were patched after flood or storm-surge events with leftover flex runs and crushed take-offs hidden in crawlspaces. These retrofits often create new leaks where the original metal meets the replacement material. We map the full system, identify every compromised joint, and seal it properly so you’re not conditioning river mud.
Sealing for Newer Subdivisions
The 1990s and 2000s builds off Route 2 often use flex duct that can sag, kink, or pull loose from registers. We re-secure and seal these connections with mastic and proper supports, restoring the airflow the builder intended before settling and vibration took their toll.
Duct Repair in Edgewater
Duct Repair in Edgewater fixes the physical damage that sealing alone won’t solve: crushed flex runs, rusted metal trunk lines, disconnected collars, and holes from rodents or contractor damage. We see this most often in the older homes near the Rhode River, where decades of crawlspace moisture have corroded sheet metal, and in homes where multiple HVAC contractors have cut into original ductwork without properly closing their access.
Repair costs in Edgewater typically run $400 – $1,200 for localized fixes, such as replacing a damaged section of flex duct or rebuilding a corroded take-off. Extensive trunk-line replacement in an older waterfront ranch can reach $1,500 – $2,800. We always inspect first, show you the damage, and give you a written price before any cutting or replacement starts.
Corrosion in Crawlspace Runs
Edgewater’s humid summers and occasional standing water after coastal storms accelerate rust in metal ductwork. We remove corroded sections, install galvanized or aluminum replacements where appropriate, and seal all connections with mastic rated for wet locations.
Disconnected and Retrofitted Systems
A common call we get: “We just bought this house and the ducts smell like river mud after a nor’easter.” Previous owners often patched flood damage with mismatched materials. We trace every run, remove the incompatible connections, and rebuild the system with proper materials and sealing.
Trusted Brands We Service in Edgewater
Our equipment comes from the same suppliers commercial crews use. We run Rotobrush rotary brush systems and Nikro negative-air machines for cleaning and preparation work, and we stock sealing and filtration products from Abatement Technologies and Guardsman. For Edgewater homeowners, this means we don’t order parts from a catalog and make you wait. Our trucks carry the mastics, tapes, and replacement duct sections needed for most same-visit repairs, and our Baltimore office keeps inventory for the less common sizes found in older homes.
Common Duct Sealing Problems We See in Edgewater Homes
- Failed tape joints in original metal ductwork. The 1960s and 70s ranches near the South River were built with sheet-metal trunk-and-branch systems sealed with cloth-backed tape that dries and falls off after fifty years. We remove the residue and reseal with mastic that flexes with temperature changes.
- Pollen and mold accumulation forcing duct separation. Edgewater’s heavy spring oak and maple pollen, combined with summer humidity, coats duct interiors and adds weight to flex runs. The resulting sagging pulls connections loose, creating leaks that worsen over time.
- Improper retrofits after flood damage. In waterfront areas along the Rhode River, we’ve found three generations of partial repairs: original metal, 1990s flex additions, and 2010s patches, none of them properly sealed to each other. The system works against itself.
- Crushed flex duct in newer subdivisions. The 1990s and 2000s homes off Route 2 often have flex duct routed through tight framing cavities. Over years, the compression restricts airflow and strains connections until they separate entirely.
Pricing for Duct Sealing in Edgewater, MD
We’re straightforward about what this costs because we’ve seen what happens when homeowners chase the lowest quote. A typical duct sealing job in Edgewater runs $850 – $1,800 for a complete system seal on a standard single-family home. Smaller partial seals or accessible repairs start around $400 – $650. Extensive repairs in older waterfront homes with buried or corroded trunk lines can reach $2,000 – $2,800.
What moves the price: system size (more ducts, more labor), accessibility (crawlspace work takes longer than attic access), and whether we’re sealing existing joints or replacing damaged sections first. We do not price per vent. We price per system, in writing, before any work starts. You’ll know the exact cost before we open a single joint. Estimates are free. Call (361) 326-5060 to schedule.

Yes. We work the older waterfront ranches along the Rhode and South rivers, the subdivisions off Route 2, and everything between. Whether your home dates to 1965 or 2005, we’ve likely sealed or repaired ductwork in a house with the same layout and the same local conditions.
Costs are comparable between Edgewater and Annapolis, though Edgewater’s older waterfront homes sometimes require more extensive repair work due to storm-surge retrofits and corrosion. We inspect and quote each home individually, so you’re not paying for Annapolis prices or conditions that don’t apply to your house.
Every duct sealing job is covered by our 365-Day Done Right Promise in writing. If the seal fails or the problem returns within one year, Hollis returns and makes it right at no charge, including a free second visit. That’s standard on every job, not an upsell.
