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.

Dryer Vent Repair in Catonsville
Dryer Vent Repair in Catonsville often means more than clearing lint, it’s fixing the original galvanized pipe, crushed flex runs, and improper terminations we find in homes from Frederick Road to Catonsville Manor. The typical repair in Catonsville runs $180 – $420 depending on how much duct needs replacement and whether we need to reroute to a proper exterior termination. Many homeowners call us for a “cleaning” and discover the real issue is a vent that’s disconnected behind a finished basement ceiling or crushed where a past HVAC crew wedged it against a joist.
Crushed and Disconnected Runs
We pull a Rotobrush camera through the line on every repair assessment. In Catonsville’s older homes, we regularly find original ductwork flattened during decades of basement renovations or HVAC swaps. The homeowner’s been blaming the dryer for years. We cut out the damaged section, re-run rigid duct where code allows, and seal every joint with proper mastic so the airflow rating matches what the dryer’s trying to push.
Crawl-Space Terminations
A surprising number of Catonsville vents terminate under porches or into unsealed crawl spaces rather than through a sidewall or roof cap. This dumps lint and moisture directly into damp framing. We reroute these to proper exterior terminations with bird guards, which protects the structure and gets the dryer performing the way it should.
Dryer Vent Cleaning Company in Catonsville
Dryer Vent Cleaning Company work in Catonsville means understanding the local housing stock: decades of accumulation in original galvanized runs, long flex additions from 1970s HVAC replacements, and the humid mid-Atlantic climate that packs lint tighter than in drier regions. A standard cleaning for a Catonsville home runs $150 – $280, with multi-vent or commercial-style setups ranging higher. We don’t quote per-vent prices that balloon at the door. One flat price per system, agreed in writing before we start.
What Our Cleaning Covers
We use Rotobrush rotary brush systems and Nikro negative-air machines to agitate and extract lint from the full run, not just the accessible portions. Afterward, we check airflow at the exterior cap and show you before-and-after photos of your own ductwork. If we find damage or improper termination, we explain it and give you a separate written price for repair. No pressure, no moving targets.
The Garrison Code on Every Job
Our technicians arrive inside the quoted window, in uniform, with the work order already written. They lay down protection, explain what they’re finding as they go, and leave the site clean. That’s not marketing language, it’s The Garrison Code, and it’s how we operate in Catonsville on every call.
Trusted Brands We Service in Catonsville
We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies on every Catonsville truck, and we stock filtration and sealing products from Honeywell, Aprilaire, and Guardsman for jobs that need more than a basic clean. For dryer vent work specifically, the Rotobrush camera and rotary systems let us see and clear runs that standard shop-vac methods miss. We keep common vent caps, bird guards, and rigid duct fittings stocked locally so repairs don’t stretch across multiple visits. When you’re dealing with a pre-1950 galvanized run or a 1970s flex addition in a Paradise ranch, having the right fitting on the truck matters. Our Dryer Vent Cleaning team doesn’t improvise with hardware-store parts.
Common Dryer Vent Cleaning Problems We See in Catonsville Homes
- Crushed galvanized runs in pre-1950 core homes. The original ductwork off Frederick Road and in Catonsville Manor was built for dryers that moved far less air. Decades later, modern dryers overwork against flattened or corroded pipe, and the homeowner assumes the appliance is failing.
- Vents terminating into damp crawl spaces instead of outdoors. After wet springs like the record 2018 rains, these terminations feed lint and moisture into already compromised framing, compounding the musty-odor problems many Catonsville basements already struggle with.
- Long, sagging flex runs from past HVAC replacements. The 1950s – 70s ranches in Paradise often have flex duct added during heating-system swaps that droops at low points, trapping lint far beyond where a standard cleaning reaches.
- Blow-and-go cleaning that never addresses the real restriction. A shop vac at the exterior cap clears surface lint but leaves crushed or disconnected runs untouched. We find this constantly in homes where another company “cleaned” the vent six months ago and the dryer’s still underperforming.
Pricing for Dryer Vent Cleaning in Catonsville, MD

Dryer vent repair, including rerouting crushed runs or replacing damaged duct to a proper exterior termination, typically falls between $180 – $420. What moves the price: the length and material of the run, whether we need to access duct behind finished ceilings, and whether the vent currently terminates in a crawl space that requires rerouting to an exterior wall or roof cap.

FAQs About Dryer Vent Cleaning in Catonsville
Yes. Pre-1950 homes in Catonsville often have original galvanized ductwork that’s narrower, more corroded, and more likely to be crushed or improperly routed than modern PVC or rigid aluminum. We use camera inspection to assess the full run before cleaning, and we carry the fittings to repair or replace damaged sections rather than forcing tools through fragile pipe. Call (361) 326-5060 for a free assessment of your specific system.
Builders in Catonsville’s early decades often ran dryer vents to the nearest convenient opening, which frequently meant under a porch or into an unsealed crawl space rather than through a proper sidewall or roof termination. It was faster and cheaper at the time, but it dumps moisture and lint into damp framing. We reroute these to code-compliant exterior terminations with proper bird guards. The fix typically runs $220 – $380 depending on the reroute length.
Most Catonsville homes need dryer vent cleaning every 12 – 18 months, though homes with long flex runs, multiple bends, or heavy laundry usage may need it annually. The humid mid-Atlantic climate here packs lint denser than in drier regions, and the older housing stock often has restrictions that accelerate buildup. If your dryer’s taking longer than one cycle, you’re already past due. Call (361) 326-5060 to schedule.
No. Dryer vent cleaning addresses only the exhaust duct from your dryer to the exterior termination. Your HVAC supply and return ducts are a separate system. That said, many Catonsville homeowners book both services together, especially after wet springs when musty odors from damp crawl spaces affect the whole house. We can assess both and give you separate written prices for each.
The restriction is almost always deeper in the run. In Catonsville, we regularly find crushed pipe, disconnected joints behind finished ceilings, or long sagging flex runs that trap lint beyond where the trap can reach. One homeowner in Catonsville Manor had been running two cycles for three years before we found a galvanized section crushed flat by a 1970s HVAC swap. After we re-ran rigid duct to a proper termination, their first load dried in one cycle. Call (361) 326-5060 and we’ll camera the line to find your restriction.
