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 Virginia Beach
Virginia Beach sits on a coastal plain where the air stays heavy with humidity and salt, and that combination takes a toll on ductwork that most inland homeowners never face. Duct sealing in Virginia Beach typically runs $450 – $1,200 for a whole-home seal, depending on system accessibility and the extent of leakage, and most jobs are scheduled within a few business days. Our crews dispatch from the Hampton Roads office and know the difference between working in a Kempsville crawlspace versus an Oceanfront attic, because the moisture problems aren’t the same block to block. If your vents blow weak, your upstairs rooms never cool, or your energy bill climbed without explanation, call us at (361) 326-5060. We’ll put a written price in your hand before any work starts.
Why Hollis Air Duct Cleaning Is Virginia Beach’s Preferred Duct Sealing Company
We’ve been sealing ducts in Hampton Roads since 2004, and our Virginia Beach customers know we don’t quote one number over the phone and deliver another when the van arrives. The Garrison Standard means written pricing, background-checked uniformed technicians, and a 365-Day Done Right Promise on every seal. If the mastic cracks, the tape lifts, or the airflow doesn’t improve, we come back and make it right at no charge, including a free second visit.
Our phones are answered by a live person 24 hours a day, seven days a week. No callback queues, no voicemail loops, no waiting until Monday to schedule. When you’re dealing with a duct system that’s bleeding conditioned air into a damp crawlspace, you want answers now, not next week.
We arrive inside the quoted window, price in writing before touching anything, and leave the site clean. That’s The Garrison Code, and it’s how our technicians operate on every Virginia Beach job, whether it’s a 1960s ranch off Great Neck Road or a two-story near Mount Trashmore.
Duct Sealing Services in Virginia Beach
Duct Sealing Services in Virginia Beach address a problem most homeowners don’t know they have: conditioned air escaping through gaps, seams, and disconnected joints before it ever reaches your rooms. In a city where summers hit the 90s with humidity to match, every cubic foot of cooled air that leaks into an attic or crawlspace is money you’re paying to comfort your insulation. Our Duct Sealing team uses professional-grade mastic compounds and reinforced foil tape, not the hardware-store duct tape that dries and fails within a year, to close every accessible seam in your system.
Most Virginia Beach homes built between 1950 and 1995 have galvanized metal ductwork or early flexible duct that’s now brittle, corroded, or sagging. Salt aerosol from the Atlantic and Chesapeake Bay accelerates rust at every joint, and the near-constant humidity keeps condensation forming on cold duct surfaces, which wicks into seams and breaks down adhesives faster than in drier climates. A typical whole-home seal runs $450 – $1,200, with partial repairs starting around $250 for accessible single-zone systems.
Leak Detection and Assessment
We pressurize your duct system and measure airflow loss at the air handler, at each vent, and at the return plenum. This isn’t guesswork; we show you the numbers. In Virginia Beach’s older neighborhoods like Thoroughgood and Princess Anne, we regularly find 25 – 40% leakage in original duct systems, much of it hidden in crawlspaces where homeowners never look.
Mastic Sealing and Joint Repair
We brush on water-based duct mastic, a thick sealant that remains flexible for decades, at every seam, collar, and connection we can reach. For joints that have separated or rusted through, we cut out the damaged section and splice in new material, priced in writing before we start cutting.

Duct Insulation in Virginia Beach
Duct Insulation in Virginia Beach is often the missing piece after sealing is done, because a sealed duct with thin or missing insulation still sweats in humid crawlspaces and loses temperature in unconditioned attics. In this climate, condensation control matters as much as heat retention. We wrap sealed ducts with fiberglass insulation and vapor-barrier jacket, or replace deteriorated original wrap that’s now mold-stained and compressed. A typical insulation upgrade runs $600 – $1,800 for a whole-home system, depending on linear footage and access difficulty.
Virginia Beach’s high water table means many crawlspaces stay damp year-round, especially in neighborhoods east of Interstate 264 where the elevation drops toward the ocean. We’ve pulled back insulation in Oceanfront crawlspaces and found the exterior wrap black with mold while the interior duct surface was still sweating. Insulation without a proper vapor barrier, or insulation that’s been wet and dried repeatedly, becomes a sponge that holds moisture against your ducts.
Vapor Barrier Replacement
We remove water-damaged insulation wrap and install new jacketing with sealed seams, so condensation forms on the outside of the vapor barrier, not on your duct metal. This stops the rust cycle and prevents musty odors from migrating through your vents.
Attic Duct Insulation Upgrades
Attic air handlers are common in Virginia Beach construction from the 1990s forward, but the flexible duct running through 130-degree attic air loses efficiency fast. We upgrade to higher R-value insulation and support sagging flex duct with proper hangers, improving both temperature delivery and airflow.
Trusted Brands We Service in Virginia Beach
Our equipment comes from the same suppliers that outfit commercial HVAC crews. We seal with mastic and tape systems from Abatement Technologies, install filtration upgrades using Aprilaire media cabinets, and carry Guardsman antimicrobial treatments for duct interiors that have seen microbial growth. For mechanical cleaning before sealing, we run Rotobrush rotary brush systems and Nikro negative-air machines. We stock common repair parts locally, so a Virginia Beach homeowner isn’t waiting a week for a specialty collar or transition fitting. When we quote a job, we know we can finish it, because the right parts are already on our shelf or available next-day from our Hampton Roads suppliers.
Common Duct Sealing Problems We See in Virginia Beach Homes
- Rust-eaten galvanized seams in mid-century ranch homes. The post-WWII building boom left Virginia Beach with thousands of ranch houses on slab and crawlspace foundations, many with original galvanized duct that has corroded through at the joints. Salt fog accelerates the damage, and by the time homeowners notice weak airflow, the metal is often too thin to seal without patching.
- Disconnected flex duct in damp crawlspaces. Flexible duct installed in the 1980s and 1990s has sagged, torn, or pulled loose from collars in Kempsville and Thoroughgood crawlspaces where humidity keeps the material soft and heavy. The connection fails, and the crawlspace gets all the conditioned air.
- Mold-compromised tape and mastic from previous repairs. We’ve opened up duct systems in Princess Anne that were “sealed” five years ago with generic tape that turned to powder in the humidity. Virginia Beach’s climate demands sealants rated for wet environments, not the cheapest product in the van.
- Standing water in low-lying duct runs after heavy rain. Nor’easters and summer thunderstorms flood crawlspaces in neighborhoods near the Lynnhaven River and other low areas. Ducts that sit in standing water corrode from the outside in, and no amount of interior sealing fixes a duct that’s rusting through its bottom.
Pricing for Duct Sealing in Virginia Beach, VA
Whole-home duct sealing in Virginia Beach typically costs $450 – $1,200. Partial sealing of a single zone or accessible area starts around $250. Duct insulation upgrades run $600 – $1,800 depending on linear footage. What moves the price: how much of your system is accessible without cutting drywall, whether we need to replace rusted sections rather than seal them, and if insulation removal and reinstallation is part of the job.

FAQs About Duct Sealing in Virginia Beach

Yes, we seal ducts from the Oceanfront to Kempsville, Thoroughgood to Princess Anne, and everywhere between. The access challenges differ, block by block, crawlspace versus attic, 1950s ranch versus 2000s two-story, and our crews know the local housing stock because we’ve worked in it for years.
We don’t classify duct sealing as an emergency service, because it’s a scheduled repair, not a safety hazard. If your system has failed completely, we recommend calling your HVAC contractor first. Once the mechanical issue is resolved, we can seal and insulate the ductwork to prevent the problem from recurring.
Virginia Beach prices fall in the same range as Hampton Roads overall, but coastal conditions here can increase repair complexity. Salt corrosion and moisture damage often mean we replace more material than seal it, which adds labor and parts cost compared to a system in drier inland condition. We price that difference honestly, in writing, before starting.
Every seal is covered by our 365-Day Done Right Promise for a full year from the date of service. If the seal fails, the mastic cracks, or airflow doesn’t improve as quoted, Hollis returns and makes it right at no charge, including a free second visit. That’s backed in writing on every job, not a verbal assurance.
