Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Call (830) 251-4560 for a written price before any work starts.
What matters in Dundalk isn’t just the masonry. It’s knowing that the original brick chimneys along streets like Dunmanway, Shipway, and the blocks off Merritt Boulevard were laid with soft Baltimore-area mortar and clay liners that were never meant to handle fifty years of freeze-thaw weather. That changes how we inspect, what we recommend, and how long the repair actually lasts.
- Written price before we start. Always. The number you approve is the number on the invoice.
- 365-Day Done Right Promise. Every repair carries a written guarantee for one full year.
- Camera inspection included. We show you photos of the flue before you spend a dollar on liner work.
Why Flint Chimney Sweep Is Dundalk’s Preferred Chimney Repair Company

Chimney Repair Companies in Dundalk
Chimney Repair Companies in Dundalk do their best work when they start with a camera run before touching a trowel. That’s how we operate. A proper repair sequence on a Dundalk rowhome or bungalow means inspecting the flue liner, the crown, the flashing, and the masonry bed joints first. Then you get photos of what’s actually wrong, a written scope of work, and a flat price agreed before anything gets fixed. Typical repairs here run $350 – $900 for crown resealing and flashing, and $1,200 – $2,800 when a section of brick needs rebuilding.
When we quote a Chimney Repair job in Dundalk, we never recommend liner work without camera evidence. If the clay tile is intact and the creosote is first-degree, we say so. Nothing gets sold on spec.
What We Check First
We start with a Level 2 camera inspection down the flue. On Dundalk rowhomes where the chimney sits on the party wall, that camera tells us whether the service cavity is dry, whether the clay liner is glazed or cracked, and whether the damper has been holding moisture against the smoke shelf. The report drives the repair list, not a sales script.
Why a Written Price Matters
Chimney repair pricing should not change between the estimate and the invoice. We write the number down before we touch brick. If the camera finds something that changes the scope, we stop, show you the photos, and give you a revised number to approve. You never get a surprise add-on after the mortar is already mixed.
Chimney Masonry Repair in Dundalk
Chimney Masonry Repair is the bread-and-butter job on Dundalk’s original brick chimneys, and wall tie replacement when the structure above the roofline has started to lean. On a 1950s rowhome off North Point Boulevard, soft mortar fails before the brick does. Water works into the joints, freezes, and pries the bed joints open. Left alone, the face of the brick starts spalling and the chimney crown cracks. Masonry repair in Dundalk tends to start with mortar replacement and crown work, not a rebuild.
A standard repointing job on a one-story Dundalk chimney runs $450 – $850 depending on how much of the stack is spalled. Crown repair or replacement adds $350 – $600. If the freeze-thaw cycles have damaged the top three or four courses of brick, partial rebuilding starts around $1,200.
Soft Mortar and Spalling on Original Dundalk Brick
Original Dundalk chimneys from the post-war building boom used a soft lime-and-sand mortar mix. It breathes better than modern cement mortar, but it wears faster. By the time the surface looks powdery and the joints are recessed a quarter inch, water is already inside the wall. Tuckpointing with a compatible mortar is the fix. Using the wrong, harder mortar actually accelerates spalling.
Party-Wall Stacks and Scaffolding
Most rowhome chimneys in Dundalk rise from a party wall, which means scaffolding and neighbor coordination often decide the schedule more than the masonry itself. We plan the material pickup, staging, and access route before we give you a date. That’s part of what a local crew gets right that an out-of-town bid can’t.
Trusted Brands We Service in Dundalk
When a Dundalk repair calls for liner replacement or crown coating, we specify product by job, not by margin. HeatShield goes in when a clay liner has hairline cracks and the smoke chamber is intact. Gelco crown coat goes on exterior crowns where water has started to soak the masonry. Olympia Chimney caps and dampers go on flues where rain and animals have been getting in. We stock the common components locally for fast turnaround on Dundalk jobs, so you’re not waiting two weeks on a part from the Midwest.
Common Chimney Repair Problems We See in Dundalk Homes
- Soft mortar joints and spalling brick. Freeze-thaw cycles in Dundalk pry open joints that looked fine in summer. By the time spalling shows on the face, water has already reached the smoke chamber.
- Missing or rusted chimney caps. Common on flat-roofed rowhome additions around the older commercial blocks. A rusted cap lets rain straight into the flue, where it becomes corrosive creosote acid.
- Third-degree creosote behind a damper that hasn’t been opened in years. The tar glaze reads as “just a little soot” from the hearth, but a camera run shows it lining the flue where a brush won’t touch it.
- Cracked crown flashing. A fall storm knocks a cap loose, and the flashing joint below has been failing for two seasons. Water soaks the smoke chamber and settles against the firebox. This is the repair order on roughly half the Dundalk calls we run.

FAQs About Chimney Repair in Dundalk
No, not every year. If you burn less than a cord and the chimney was clean at the last sweep, every other year is reasonable. What matters in Dundalk is water, not soot. The freeze-thaw cycle is working on your mortar whether or not you light a fire. A camera inspection once every two years catches spalling and crown cracks before they become a rebuild. Call (830) 251-4560 and we’ll tell you if you can safely wait another season.
You usually can’t tell from the hearth. Third-degree creosote is a hard, shiny glaze that forms on the flue walls above the damper, where the temperature drops. It doesn’t brush out, and it’s the condition most likely to fuel a chimney fire. The only way to see it is a camera run. We include photos in our inspection report, so you see the glaze yourself before anyone recommends removal.
We can tell you the range for common repairs in Dundalk, and we can give you a firm written price once we’ve run the camera. Crown and flashing work runs $350 – $900. Tuckpointing runs $450 – $850. Partial rebuilds start at $1,200. The written quote comes before any work begins, and that’s the number on the invoice. Call (830) 251-4560 for a free estimate and a straight answer on what your chimney probably needs.
The fire risk is real but specific. Third-degree creosote can ignite at around 2,000 degrees, and once it catches, the flue becomes a blowtorch inside your wall. Carbon monoxide risk builds when a cracked flue liner or blocked damper sends exhaust into the house instead of up the stack. On an older Dundalk rowhome with original clay tile, a liner crack above the smoke chamber is exactly that path. A $350 inspection is the cheapest way to know which side of that line your chimney is on.
Yes. A party-wall chimney is shared space, and anything structural touches both sides of the property line. That affects access, scaffolding, and sometimes the timing of the work. We’re used to running repairs on party-wall stacks in Dundalk, and we flag any neighbor coordination in the written scope before you commit. The masonry work itself is the same, but the planning has to be sharper. Call (830) 251-4560 and we’ll walk you through it.
