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’ve been driving out to Richmond since Hollis started taking calls in the East Bay, and our dispatch team at the Washington, DC office routes crews to Richmond homes seven days a week. If you’re in the Iron Triangle, Santa Fe, or up in the Richmond Annex, we’ll give you a written arrival window and stick to it. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Richmond’s Preferred Duct Sealing Company
Richmond homeowners know the difference between a crew that understands this city’s housing stock and one that’s just passing through. We’ve sealed ducts in 1920s Victorians near Point Richmond where galvanized steel runs through unconditioned crawl spaces, and in postwar tract homes in El Sobrante with original flexible ductwork that’s cracked at every joint. That history matters when we’re pricing the job.
Our technicians are background-checked and uniformed, and they follow The Garrison Code on every Richmond job: arrive inside the window, price in writing before touching anything, finish by the book, leave the site clean. The 365-Day Done Right Promise backs every seal we apply. If it fails within a year, we come back and make it right at no charge, including a free second visit.

Duct Sealing Services in Richmond
Duct Sealing Services in Richmond address a problem most homeowners don’t know they have: conditioned air escaping through gaps, cracks, and failed joints before it ever reaches your rooms. In Richmond’s climate, where foggy summers mean HVAC systems run more for air circulation than temperature control, those leaks force your blower to work harder and longer. We apply duct sealing mastic, a thick, fiber-reinforced compound that fills gaps permanently, and back it with metal-backed tape at high-stress joints. A typical whole-home seal in Richmond runs $450 – $1,200 depending on accessibility and duct material.
Supply Duct Sealing
Supply ducts carry heated or cooled air to your rooms. In Richmond’s older homes, we often find separated connections where flexible duct meets rigid trunk lines, especially in crawl spaces that see moisture from the marine layer. We reattach and seal these points with mastic rated for the temperature swing.
Return Path Repair
Return ducts pull air back to your HVAC unit. When they’re leaky, they draw in crawl space dust, garage fumes, or that oily residue we see near refinery-adjacent neighborhoods. We seal returns completely so your system breathes only the air inside your home.

Duct Insulation in Richmond
Duct Insulation in Richmond solves a different problem than sealing: thermal loss through thin duct walls in unconditioned spaces. Richmond’s cool, foggy summers mean ducts in attics and crawl spaces sweat when cold supply air meets humid outside air, and that moisture breeds mold. Insulation wraps the duct in a thermal blanket, typically R-6 or R-8 fiberglass with a vapor barrier, so the air inside stays at temperature until it reaches your vent. A typical duct insulation job in Richmond runs $600 – $1,800 depending on linear feet and access difficulty.
Vapor Barrier Installation
We install insulation with an intact vapor barrier facing outward, which matters in Richmond where salt-laden marine air penetrates crawl spaces. Without this barrier, moisture condenses between the insulation and duct metal, accelerating corrosion.
Attic Duct Wrapping
Attic ducts in Richmond’s mid-century homes often run through spaces that hit 140°F in a rare hot spell. We wrap these runs with higher-R material and seal the insulation jacket with mastic at seams, so your cooling doesn’t bake off before it drops into the living space.
Trusted Brands We Service in Richmond
We carry filtration and sealing products from Honeywell, Aprilaire, and Abatement Technologies on our Richmond trucks, and we stock mastic and metal-backed tape from Nikro for same-day repairs. If your system needs a component we don’t have, our supplier relationships mean we can typically source it within 24 hours. We don’t substitute brands without telling you, and we don’t mark up parts beyond what we paid. The price on your written estimate is the price at completion.
Common Duct Sealing Problems We See in Richmond Homes
- Industrial soot infiltration in refinery-adjacent neighborhoods. In Santa Fe and the Iron Triangle, we regularly open duct systems to find that distinctive black, oily residue from decades of Chevron emissions. Standard mastic won’t adhere to this surface; we degrease with specialized cleaner before sealing.
- Failed flexible duct connections in postwar housing. Richmond Annex and El Sobrante homes built in the 1950s – 1970s often have original flexible ductwork that’s brittle at the collar connections. We replace damaged sections and seal new to old with transition fittings.
- Undersized returns in prewar Victorians. Point Richmond homes with forced-air retrofits frequently have return ducts too small for modern blower capacity. The resulting negative pressure pulls air from every leak; we seal what we can and flag undersizing for your HVAC contractor.
- Earthquake-shifted duct runs. Richmond’s position on the Hayward Fault means seismic events can separate duct joints in crawl spaces. After any significant shaking, we recommend a pressure test to find leaks that weren’t there last season.
Pricing for Duct Sealing in Richmond, VA
Whole-home duct sealing in Richmond typically costs $450 – $1,200. A small system with accessible ducts in a crawl space runs toward the lower end. A larger home with attic runs, multiple zones, or the need for soot degreasing before sealing pushes toward the higher end. Duct insulation adds $600 – $1,800 depending on linear footage.
We don’t quote per-vent or offer teaser coupons that balloon at the door. One flat price per system, agreed in writing before work starts. That price includes materials, labor, and the pressure test to verify our work. Estimates are free. Call (361) 326-5060.
