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 Baltimore
Baltimore Dryer Vent Cleaning typically costs $120 – $280 for a standard residential job, with repairs or rerouting in older rowhouses running $200 – $450 depending on access. We’re local to Baltimore, dispatching crews from our metro office to neighborhoods from Hampden to Federal Hill, and we usually book within a few days, not weeks.
We’ve been working on Baltimore’s housing stock since 2004, and we know what we’re walking into: century-old rowhouses with original galvanized duct chases, vent runs that were retrofit through shared party walls, and lint accumulation that’s often hiding inside wall cavities where a standard cleaning can’t reach. Our Dryer Vent Cleaning team uses camera inspection, rotary brush systems, and negative-air equipment to find the real problem before we quote a price. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Baltimore’s Preferred Dryer Vent Cleaning Company
Baltimore homeowners call us because we’ve seen what their homes hide. In rowhouse corridors from Hampden to Canton, we’ve pulled pounds of lint from disconnected galvanized runs that were dumping exhaust into shared wall cavities for years. Our technicians are background-checked, uniformed, and trained to The Garrison Code: arrive inside the window, price in writing, leave the site clean.
Every job gets a written price before we touch anything, and every repair is backed by our 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. When you’re smelling burnt lint in your basement or your dryer’s taking two cycles, you don’t want voicemail.
We serve Baltimore from our local metro office, with crews who know the difference between a Federal Hill three-story and a Hampden narrow row, and what each means for vent access and airflow.
Dryer Vent Installation in Baltimore
Dryer Vent Installation in Baltimore is often a rescue mission on century-old housing. Original vent runs in rowhouses were frequently cobbled together with galvanized pipe, flexible foil, or whatever was handy in the 1970s retrofit, and they’re now crushed, corroded, or disconnected inside walls we can’t easily open.
A proper installation here means rigid aluminum pipe, sealed joints, and a termination point that actually exhausts to the exterior, not into a shared wall cavity or unheated crawlspace. In Baltimore’s market, a standard dryer vent installation runs $180 – $350 for accessible basement or first-floor runs; second-floor or through-wall installations in tight rowhouse footprints run $300 – $550 due to the fishing and plaster repair involved.
When Installation Beats Repair
We recommend full replacement when the original galvanized chase is too corroded to seal, when multiple hidden joints have failed, or when the vent run exceeds 25 feet without proper slope and support. In Canton rowhouses, we’ve found runs that traveled 40 feet through three turns before reaching daylight, which is why the dryer never worked right.
Rigid Aluminum and Proper Slope
We build in rigid aluminum with a minimum 1/4-inch-per-foot slope back toward the dryer, so condensation drains instead of pooling. Every joint gets high-temperature mastic sealant, not foil tape that degrades. We terminate with a backdraft damper, not a flimsy plastic louver that wasps clog in Baltimore’s humid summers.
Dryer Vent Repair in Baltimore
Dryer Vent Repair in Baltimore usually starts with a camera inspection because the failure is rarely where you can see it. We find disconnected joints behind plaster, crushed sections where someone forced a duct through a too-small chase, and terminations that look fine from the outside but are blocked by corroded screens or wasp nests.
Repair pricing in Baltimore runs $120 – $280 for accessible joint repairs and termination replacements; $200 – $400 when we need to open a wall section or rebuild a run through a shared party wall. We always inspect first, show you the footage, and write the price down before any work starts.
Party-Wall Leaks and Cross-Contamination
Baltimore’s century-old rowhouses commonly have dryer vent runs that were retrofit through shared party walls and original galvanized duct chases, and because those chases were never sealed, the dryer’s exhaust can migrate into neighboring units’ basements or living space rather than reaching the exterior. We seal these chases with fire-rated materials and install proper backdraft dampers as part of our Duct Sealing in Baltimore to isolate each unit’s airflow.
Freeze-Thaw Damage in Crawlspaces
Vent runs through unheated crawlspaces in neighborhoods like Roland Park suffer condensation every winter. The moisture mats lint into a hard paste that restricts airflow and corrodes metal. We replace damaged sections with insulated rigid pipe and verify the entire run with airflow meters before we leave.
Trusted Brands We Service in Baltimore
We stock parts and use equipment that holds up to Baltimore’s humidity and aging housing stock. Our rotary brush systems come from Rotobrush, our negative-air machines from Nikro, and our filtration and backdraft components from Honeywell, Aprilaire, and Guardsman. We carry rigid aluminum pipe, high-temperature mastic, and proper termination caps in our Baltimore-stocked vans so most repairs don’t wait on parts. When your vent run needs a Guardsman damper or a Honeywell-compatible termination, we install it same visit, not next week.
Common Dryer Vent Cleaning Problems We See in Baltimore Homes
- Hidden disconnections in shared wall cavities. In Hampden and Federal Hill rowhouses, original galvanized joints behind plaster walls separate over decades of vibration, dumping lint into the cavity between units. Camera inspection finds it; standard brushing misses it entirely.
- Freeze-thaw condensation matting lint in crawlspace runs. Baltimore’s winter temperature swings cause moisture accumulation in unheated basement and crawlspace duct sections. The lint hardens into a paste that rotary brushing alone won’t clear; we use negative-air extraction and targeted agitation.
- Corroded exterior terminations on brick walls. Humid summers and salt air near the harbor rust out flapper dampers and screen covers. Wasps and ivy compound the blockage. The dryer runs but exhaust has nowhere to go.
- Coal dust infiltration at floor registers. In neighborhoods with original duct systems, gaps at floor registers suck in century-old coal dust from basements. The vent run may be clear but the air moving through it is contaminated; sealing the chase perimeter is part of the fix.

FAQs About Dryer Vent Cleaning in Baltimore
Original vent runs were retrofit through unsealed galvanized chases in shared party walls, so exhaust migrates between units and lint accumulates in wall cavities, not just the duct. We seal chases and rebuild runs to isolate airflow properly. Call (361) 326-5060 for an inspection and exact quote.
Burning lint smell in the basement, moisture stains on shared walls, or a dryer that still performs poorly after cleaning are warning signs. We use camera inspection to trace the full run and identify leaks at hidden joints. Call (361) 326-5060 for an inspection and exact quote.
Winter temperature swings cause moisture to condense in unheated crawlspace and basement duct sections, matting lint into a hard, airflow-blocking paste that corrodes metal and breeds mold. We clear it with negative-air extraction and replace damaged sections with insulated rigid pipe. Call (361) 326-5060 for an inspection and exact quote.
Yes. We remove corroded galvanized pipe, rebuild in rigid aluminum with sealed joints and proper slope, and fire-seal any chase penetrations in shared walls. Most replacements run $200 – $450 depending on access and length. Call (361) 326-5060 for an inspection and exact quote.
The vent run is likely blocked or disconnected behind a wall. In Federal Hill, we’ve found crushed galvanized sections and separated joints hidden in original plaster chases that lint traps can’t address. Camera inspection locates the failure; repair or replacement restores single-cycle drying. Call (361) 326-5060 for an inspection and exact quote.
