We know Dundalk. We’ve been driving the grid of 1920s and 1930s brick rowhouses off Dundalk Avenue and Holabird Avenue for decades, and we’ve swept chimneys in every corner of 21222. The salt air off Back River hits these old masonry stacks harder than inland Baltimore County. The flues were built for coal, converted to gas or oil by owners in the 1970s and 1980s, and too many never got the liner upgrade the job required. That combination-age, salt, and unpermitted fuel conversions-means Dundalk chimneys need a sweep who understands what they’re looking at, not just a brush on a pole.
Our technicians are background-checked, uniformed, and arrive with DuraFlex and HeatShield materials on the truck. We complete most jobs in one visit. Call (844) 803-1545 and a live person answers, 24 hours a day.

Our Chimney Cleaning & Sweep Services in Dundalk
Level 1 Inspection
A Level 1 inspection is the annual baseline every Dundalk homeowner with a fireplace or heating appliance should schedule. We examine the readily accessible portions of your chimney structure, flue, and connections for obstructions, creosote buildup, and basic soundness. In Dundalk’s 1920s-1950s brick housing stock, we’re specifically checking for the deterioration pattern that salt-laden air off Bear Creek accelerates: spalling brick, eroded mortar joints, and crown cracks that let water into the flue. A Level 1 inspection in Dundalk runs $189-$249 and takes about 45 minutes. We end with photos and a written verdict.

Level 2 Inspection
Level 2 is required when you’re buying or selling a home, after a chimney fire, or following any structural event like a lightning strike or earthquake. We run a camera up the full length of the flue, documenting every joint, every crack, every glaze of creosote. In Dundalk, this inspection regularly reveals what we call the “Sparrows Point special”: an original coal-era terra-cotta flue tile that’s now serving a gas insert without a proper stainless liner, creating dangerous condensation and draft problems that a standard visual sweep would miss. Level 2 inspections in Dundalk cost $349-$499. You get the video, the photos, and a plain-English report.

Creosote Removal
Creosote is the combustible residue that builds up when wood or solid fuel burns incompletely. Dundalk’s older, often oversized flues are particularly prone to heavy Stage 2 and Stage 3 glaze deposits because the draft is wrong for the appliance now connected. We’ve pulled creosote deposits an inch thick from flues off North Point Road where the homeowner had been burning seasoned hardwood but the flue was simply too large for the insert. Standard creosote removal in Dundalk falls within our $189-$329 sweep range. Heavy glaze requiring rotary cleaning or chemical treatment runs $379-$549. We assess it during the initial inspection and quote upfront.

Soot Removal
Soot accumulation from oil and gas appliances is different from wood creosote-finer, more acidic, and equally capable of blocking proper draft. Many Dundalk homes still run original oil furnaces venting into these old masonry chimneys, and the soot combines with condensation from the oversized flue to form a corrosive sludge that attacks the terra-cotta lining. Our technicians use HEPA-containment equipment to protect your home during cleaning. Soot removal service in Dundalk starts at $189 and is typically completed in under two hours.

Trusted Brands We Service in Dundalk
We stock professional-grade materials from Famco, Copperfield, and DuraFlex on every truck serving Dundalk. That means when your inspection reveals a cracked flue liner, a failed damper, or a chimney cap rusted through from Back River salt air, we don’t need to order parts and reschedule. We measure, cut, and install on the same visit. HeatShield and Gelco products are also available for crown repair and relining jobs that require more extensive work. No builder-grade substitutes. The brands we carry are the ones professional sweeps have trusted for decades because they hold up in conditions exactly like Dundalk’s.
Common Chimney Cleaning & Sweep Problems We See in Dundalk Homes
- Unlined flues in converted coal chimneys. The original terra-cotta liner in your 1930s rowhouse off Dundalk Avenue was sized for a coal furnace. When a previous owner switched to gas or oil without pulling a permit or installing a stainless liner, they left you with a flue that condenses water, destroys mortar, and collects creosote at dangerous rates. We find this pattern weekly in 21222.
- Salt-air spalling on brick and mortar. Dundalk’s position between Back River and Bear Creek exposes chimneys to persistent salt humidity that inland Essex or Rosedale properties simply don’t face. The freeze-thaw cycle opens hairline cracks in mortar joints, and by spring the face of the brick is flaking off. Annual sweeping catches this early, before water enters the flue.
- Blocked flues from animal nesting. Squirrels, raccoons, and chimney swifts love the tall, un-capped masonry stacks of Dundalk’s older housing stock. We removed a raccoon nest from a flue off Merritt Boulevard last October that had completely blocked a furnace vent. The homeowner had no idea until the carbon monoxide detector sounded.
- Improperly sized inserts in oversized fireboxes. The mid-century conversion wave in Dundalk-when Bethlehem Steel was contracting and homeowners were patching systems on the cheap-left many chimneys with gas inserts shoved into fireboxes built for coal grates. The result is a chimney that doesn’t draft properly, soots up faster, and creates a persistent smoke smell in the house. Our camera inspection identifies the mismatch.
Pricing for Chimney Cleaning & Sweep in Dundalk, MD
We believe in no-hassle upfront pricing. The number on the estimate is the number on the invoice.
| Service | Typical Range in Dundalk |
|---|---|
| Level 1 Inspection & Sweep | $189 - $249 |

Several factors can push a job toward the higher end of these ranges. A chimney that hasn’t been swept in ten years will have more buildup. A flue with multiple bends or offsets takes longer to camera and clean. Access issues-steep roofs, tight alleyways between Dundalk’s attached rowhouses-add time. We assess everything on site and quote before we start. Estimates are free. Call (844) 803-1545 for yours.
We also offer $50 off any repair over $250, a free second opinion on any written estimate you’ve received, and a permanent 5% senior and veteran discount.

Dundalk pricing runs comparable to Essex and Rosedale, sometimes slightly higher than Edgemere or Rossville due to access challenges in the older, denser rowhouse neighborhoods. The bigger cost driver is almost always chimney condition, not location. A well-maintained Dundalk flue sweeps at our standard $189-$249 rate. One with twenty years of deferred maintenance, unlined conversion damage, or heavy creosote glaze will require more labor and fall in the $379-$549 range.
