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.

We’ll show up in the window we promised, price the job in writing before we touch anything, and stand behind it for a full year.
Why Hollis Air Duct Cleaning Is Albany’s Preferred Duct Sealing Company
We’ve been working on Albany’s distinctive housing stock since 2004 as part of the Garrison Partners family, and that longevity matters here because this city throws problems you don’t see in newer suburbs. Our technicians know the difference between a 1920s gravity-furnace trunk line and a 1960s flex-duct retrofit, and they seal them differently. Every tech is background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing, work by the book, leave the site clean.
Our 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 to schedule. The 365-Day Done Right Promise covers every job in writing: if the seal fails or the leak returns within a year, we come back and make it right at no charge, including a free second visit.
We don’t bait-and-switch with a low teaser price that balloons once the van is in your driveway. The price is written down before any work starts, and it does not move at the door. That’s The Garrison Standard, and it’s how we operate in Albany and every city we serve.
Duct Sealing Services in Albany
Duct Sealing Services in Albany address a specific set of problems caused by this city’s aging housing stock and coastal climate. Most Albany homes lose 20-30% of conditioned air through leaks in the ductwork, according to Department of Energy estimates, and here that loss is compounded by uninsulated crawlspace runs that sit in marine-layer damp for months. Our crew uses professional-grade mastic and reinforced mesh to seal seams, joints, and disconnected collars at the air handler, then pressure-tests the system to verify the fix. A typical duct sealing job in Albany runs $450 – $950 for a single-system home, depending on accessibility and how many leaks we find.
Gravity-Furnace Trunk Sealing
Original octopus furnaces in Albany’s pre-WWII bungalows used oversized galvanized steel trunks with hand-folded seams that have worked loose over 80-plus years. We seal these with duct mastic rated for the temperature swing, not tape that dries and peels. The goal is stopping the suction that pulls crawlspace air into the return side.
Flex-Duct Collar Repair
Mid-century ranch additions in Albany often have kinked or torn flex-duct collars at the plenum. We replace damaged sections with new insulated flex, seal the connection with mastic and a mechanical strap, and verify with a smoke pencil that no air is escaping into the crawlspace.

Duct Insulation in Albany
Duct Insulation in Albany is not optional for most homes built before 1970. The uninsulated metal runs under Albany’s bungalows sit in cool, damp crawlspaces where condensation forms on the exterior of the duct every time the furnace cycles. That moisture drips onto the crawlspace floor, feeds mold inside the duct, and rusts out the seams from both sides. We wrap accessible trunk lines with fiberglass duct insulation and a vapor barrier, then seal the insulation jacket at every joint so humid air cannot reach the metal. A typical duct insulation job in Albany runs $600 – $1,400, depending on linear feet of accessible duct and whether we need to remove old, waterlogged insulation first.
Crawlspace Run Encapsulation
Shallow crawlspaces under Solano Hill and Ocean View homes are notorious for pest debris and moisture. Where the duct runs through these spaces, we insulate and seal the trunk as a single system so the crawlspace air stays on its side of the duct wall. This stops the condensation cycle that ruins seals within a season.
Vapor-Barrier Integration
Marine-layer damp in Albany means standard insulation without a proper vapor barrier will saturate within two winters. We use insulation products with integrated vapor barriers, sealed with foil tape at seams, so the warm air inside the duct never meets the cool, humid crawlspace air.
Trusted Brands We Service in Albany
We carry equipment and parts from Rotobrush, Nikro, Abatement Technologies, Aprilaire, and Guardsman, and we stock common sealing and insulation materials for Albany’s housing types so we’re not ordering parts while your job sits half-finished. Our rotary brush systems and negative-air machines are the same models commercial crews use in hospitals and schools, not hardware-store rentals. When we seal a duct in Albany, we use mastic and mesh rated for the temperature and pressure of your specific system, and we explain what we’re applying and why before we open the first can.
Common Duct Sealing Problems We See in Albany Homes
- Eucalyptus debris in exterior intakes. In Ocean View and Solano Hill, we regularly find return plenums packed with eucalyptus leaves and seed pods that have blown in from the street trees. The debris decomposes in the damp crawlspace and feeds mold colonies that no amount of sealing will fix until the source is removed.
- Failed tape repairs on gravity-furnace seams. Homeowners or prior handymen often wrapped leaky trunk seams with foil tape that dried out and peeled within a year. The underlying leak path stays open, and humid marine air continues condensing inside the uninsulated metal run.
- Undersized flex ducts choking airflow. Post-war tract homes in Albany often have 1950s flex-duct additions that were too small from day one. The high static pressure blows out seals at the plenum collar, and simply re-taping the collar without addressing the sizing problem guarantees the leak returns.
- Return-side leaks pulling crawlspace air. Many Albany sealing jobs focus only on the supply trunk while leaving torn return flex collars open. This creates negative pressure that sucks damp, debris-laden crawlspace air directly into the system, bypassing the filter entirely.
Pricing for Duct Sealing in Albany, CA
A typical duct sealing job in Albany runs $450 – $950 for a single-system home with accessible crawlspace ductwork. Duct insulation adds $600 – $1,400 depending on linear feet and whether we’re removing waterlogged old material. What moves you within that range: how many leaks we find, whether the ductwork is galvanized steel or flex, accessibility in your crawlspace, and whether we need to pair sealing with source removal of debris or mold-affected insulation.

FAQs About Duct Sealing in Albany
Albany’s mild climate is actually part of the problem. Heating systems run less than in inland areas, so dust, eucalyptus debris, and moisture sit in the ducts instead of being dried out and blown through regularly. The marine layer keeps crawlspaces damp year-round, and that moisture condenses on uninsulated metal ductwork every time the furnace cycles. Call (361) 326-5060 for a free inspection if you smell musty air from your registers.
It does if the smell is coming from leaks in the ductwork pulling damp crawlspace air, but only if sealing is paired with source removal of the debris causing it. In Solano Hill, we regularly find eucalyptus leaves and seed pods that have decomposed inside the duct. Sealing the leak without removing the debris mat leaves the food source for mold in place. We seal after source removal, then camera-inspect to confirm the run is clear.
Yes, original gravity-furnace ductwork can be sealed, but it requires a different approach than modern forced-air systems. The oversized galvanized steel trunks in Albany’s 1910s-1940s bungalows have hand-folded seams that need mastic and mesh, not tape. We also check for asbestos insulation on older pipes, which must be handled by a certified abatement contractor before we can seal. We’ll tell you exactly what we’re working with before we quote.
No. A fogging sanitiser does not remove the eucalyptus debris, dust, or mold-affected insulation that we find in Albany ducts. It leaves the food source in place and temporarily suppresses odor while microbial growth continues in the cool, damp dark. Source removal with HEPA filtration under negative pressure, followed by proper sealing, is what actually fixes the problem. We do not sell fogging upsells.
We pressure-test the system after sealing and show you the before-and-after numbers. We also camera-inspect the trunk lines so you can see the clear run, not just take our word for it. The 365-Day Done Right Promise covers you in writing: if the leak returns or a new one opens within a year, we come back at no charge, including a free second visit. Call (361) 326-5060 to schedule an estimate.
