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 Dryer Vent Cleaning Across Randallstown
Dryer vent cleaning in Randallstown typically runs $180 – $340 for a standard single-family home, and most jobs take 60 to 90 minutes from arrival to cleanup. We’re Hollis Air Duct Cleaning, and our Randallstown crews know the split-levels and ranch homes that dominate this market inside and out. Dispatch and scheduling are coordinated from our Baltimore office, but the technicians who pull into your driveway live and work this corridor daily. They understand how Randallstown’s 1950s – 1970s housing stock, Baltimore’s sticky summers, and decades of accumulated lint interact in ways that slow dry times and raise fire risk. If your dryer’s taking two cycles or your laundry room smells warm and metallic, call (361) 326-5060. We’ll give you a written price before we touch anything.
Why Hollis Air Duct Cleaning Is Randallstown’s Preferred Dryer Vent Cleaning Company
We’ve been serving Randallstown homeowners since 2004 as part of the Garrison Partners family, and our reputation here was built on showing up inside the window and pricing in writing, not on teaser coupons that balloon at the door. Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive squared away, explain what they find, finish clean.
The 365-Day Done Right Promise backs every job. If the work fails within a year, we return and make it right at no charge, including a free second visit. That guarantee is written on every invoice, not implied.
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.
Our crews carry professional-grade equipment from Rotobrush and Nikro, the same rotary brush systems and negative-air machines commercial crews use, because Randallstown’s aging galvanized vent runs often need more than a hardware-store brush kit can deliver.
Dryer Vent Installation in Randallstown
Dryer Vent Installation in Randallstown becomes necessary when the original vent run is too damaged, too long, or improperly routed to clean safely. In this market, we most often replace galvanized steel pipe that has rusted through at the joints, crushed flex transitions behind the dryer, or runs that terminate in crawl spaces or attics instead of outside. A new installation in Randallstown typically costs $350 – $650 depending on the routing complexity, materials, and whether we need to core a new exterior wall penetration.
When Replacement Makes Sense
We recommend full replacement when camera inspection shows rust holes, separations at glued or taped joints, or a run exceeding 35 feet of equivalent length with turns. Randallstown’s 1960s split-levels often have vent runs that share a chase with the original return trunk, and when that geometry has failed, patching individual sections usually wastes money.
Rigid Pipe and Proper Sealing
We build new runs with smooth-wall rigid aluminum or galvanized pipe, not the corrugated flex that traps lint. Every joint gets sealed with high-temperature mastic rated for dryer exhaust, and the exterior termination receives a proper vent cap with backdraft damper, not a flimsy plastic louver that birds can breach.
Dryer Vent Repair in Randallstown
Dryer Vent Repair in Randallstown addresses localized failures without replacing the entire run. Common fixes here include reattaching separated sections at the furnace plenum, replacing rusted sheet metal screws that have created debris dams, installing bird guards over exterior terminations, and repairing crushed flex transitions. Most repairs in Randallstown fall between $150 – $280, with simple cap replacements or bird guard installations at the lower end and plenum-adjacent rework at the higher end.
Rusted Joints and Debris Dams
We regularly find sheet metal screws rusted through in the original vent pipe of 1960s split-levels on Randallstown’s west side. These failures create hidden lint dams just past the furnace plenum that brushing alone won’t clear. We cut out the compromised section, install a coupling or replacement length, and seal with mastic rated for the temperature cycling of dryer exhaust.
Bird Guard and Cap Replacement
Exterior vent caps in Randallstown take a beating from Baltimore’s freeze-thaw cycles and summer humidity. We stock replacement caps with integrated bird guards and backdraft dampers, so the fix is done in one trip, not two.
Trusted Brands We Service in Randallstown
Our Dryer Vent Cleaning crews arrive with equipment from Rotobrush and Nikro, rotary brush systems and negative-air machines built for commercial-grade agitation and extraction. For filtration and sealing products, we carry Honeywell, Aprilaire, Abatement Technologies, and Guardsman components. We keep common vent cap sizes, rigid pipe lengths, and high-temperature mastic stocked locally, so most Randallstown repairs don’t wait on parts orders. When we inspect your vent and identify a failure, we explain which material we’re using and why it fits your specific run, not just a generic “good, better, best” upsell.
Common Dryer Vent Cleaning Problems We See in Randallstown Homes
- Shared chase with original return trunk. In Randallstown’s 1960s west-side split-levels, the dryer vent run often shares a chase with the original unlined return trunk. Rusted-through sheet metal screws and debris dams just past the furnace plenum choke both systems simultaneously, trapping lint where the homeowner can’t see it.
- Humidity-caked lint in uninsulated galvanized runs. Randallstown sits in the Mid-Atlantic humid subtropical zone where summer dew points exceed 65°F. That moisture condenses on cold metal duct walls and cakes lint into a felted mat that ordinary brushing won’t dislodge without rotary agitation tools.
- Crushed flex transitions on ranch layouts. The 1950s – 1970s ranch homes common in Randallstown often have the dryer pushed tight against the wall, crushing the flex transition and collapsing the lint pathway. Homeowners sometimes replace the dryer itself when the real problem is a $200 vent repair.
- Improper terminations in crawl spaces or attics. Older Randallstown homes occasionally vent dryers into unfinished spaces instead of through an exterior wall. This dumps moisture and lint into structural cavities, feeding mold and creating genuine fire hazards that code now prohibits.

FAQs About Dryer Vent Cleaning in Randallstown
The split-levels built in Randallstown during the 1960s often route the dryer vent through a shared chase with the original unlined return trunk, creating a longer, more convoluted lint pathway with multiple turns and rust-prone joints. Your old apartment likely had a short, straight run to an exterior wall. In Randallstown’s humidity, that extended geometry traps moisture and compacts lint into clogs that need professional agitation to clear. Call (361) 326-5060 and we’ll camera the run to show you exactly where the bottleneck is.
We can clean it if the pipe is intact, but we often find that 70-year-old galvanized steel in Randallstown has rusted through at the joints or developed pinholes that leak lint into wall cavities. Our camera inspection determines which condition applies to your specific run. If replacement is needed, we quote the full job in writing before cutting anything. Call (361) 326-5060 to schedule an inspection.
The combination of lint accumulation and Randallstown’s humid subtropical summers creates a specific risk profile: moisture-compacted lint dries into a dense, flammable mat that restricts airflow and forces the dryer to overheat. Warning signs include dry times exceeding 50 minutes, a burning or metallic smell from the laundry room, or the exterior vent cap showing little airflow when the dryer runs. If you notice any of these, the vent needs immediate inspection. Call (361) 326-5060.
Yes. Our Nikro negative-air machines create containment at the vent opening, and we exhaust through HEPA filtration so disturbed lint and particulate don’t migrate into your living space. This matters especially in Randallstown’s older homes, where the shared chase between dryer vent and return trunk can pull debris into the HVAC system if not properly isolated during cleaning.
Yes, and we often recommend it. Since the two systems share geometry in many Randallstown split-levels, cleaning one without addressing the other leaves debris dams that will recirculate. We also offer Air Duct Cleaning in Randallstown to handle both systems properly. We price both systems separately in writing before starting, and completing them together saves you a second trip charge. Call (361) 326-5060 for a combined estimate.
