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.

AfterFast, Reliable Chimney Repair Across Baltimore
Chimney repair in Baltimore typically runs $350 to $2,800 depending on what’s actually wrong, and most jobs we quote take one crew day or less. In a city where half the housing stock shares a masonry party wall, the real question isn’t just “what’s broken on my side?” It’s “what’s happening to the whole stack?” We serve Baltimore rowhouses from Federal Hill to Hamilton, and we quote a written price before any tool comes off the truck. Call (830) 251-4560 and Hank Delano will walk you through what to expect.
We know Baltimore chimneys because we work on them every week. Nineteenth-century brick, coal-conversion flues, flat-roof parapet stacks, and freeze-thaw cycles that punish exposed masonry from November to March. That local knowledge changes how we inspect, what we quote, and what we tell you can safely wait.
Why Flint Chimney Sweep Is Baltimore’s Preferred Chimney Repair Company
Flint Chimney Sweep has operated since 2002 as part of the Garrison Partners family of independently owned chimney service companies. Every Baltimore job runs under The Garrison Standard: a written scope, a written price before work begins, and a 365-Day Done Right Promise in writing on every repair. If a covered repair fails within one year, we return at no charge. No argument, no re-quote.
Baltimore homeowners tell us the same thing again and again: they’ve had a chimney company quote a sweep, then “find” $4,000 worth of work once they’re on the roof. That doesn’t happen with us. The price you approve before the job is the price on the invoice. We use camera inspection for any repair recommendation so you see exactly what our technician sees, and you get a photo report to keep.
Our techs are background-checked and uniformed. You know who’s walking through your door. And when a January cold snap cracks a crown and water is running into your neighbor’s flue, a live person answers our phone 24/7 at (830) 251-4560. No voicemail trees, no callback forms.
Chimney Crown Repair in Baltimore
Chimney Crown Repair in Baltimore is the single most common masonry repair we quote on rowhouse stacks, and it’s the one most likely to show up as a problem on your neighbor’s side before you ever see it on yours. The crown is the concrete cap at the top of the chimney that sheds water away from the flue and the brick below it. A hairline crack in October lets water in. Baltimore’s freeze-thaw cycle does the rest: water freezes, expands, and turns a hairline crack into a spalled, crumbling crown by March.
A standard crown repair in Baltimore runs $450 to $1,200 depending on crown size, damage depth, and whether we’re working on a single-family stack or a shared party-wall stack that needs both sides addressed. We tear out the failed concrete, prep the surface, and pour a new crown with proper slope and drip edge so water moves off the stack instead of into it.
What a Crown Repair Involves
First we clean loose debris and spalled concrete off the crown. Then we assess whether the damage is surface-level or structural. If the crown has failed badly enough to let water into the chimney chase, we’ll recommend a Level 2 camera inspection to check the flue and smoke chamber before we pour anything. You get the photo report before you approve the repair.
Why Baltimore Crowns Fail Faster
Baltimore’s older rowhouses were built with lime-based mortars and crowns poured long before modern concrete additives existed. Combine that with January and February freeze-thaw cycles and you get crowns that fail every few years. A properly poured, properly sloped crown with a drip edge lasts decades. That’s the standard we build to.
Chimney Repair Companies in Baltimore
Chimney Repair Companies in Baltimore come in two types: General contractors who do gutters, roofs, and “some chimneys,” and dedicated chimney service companies that do nothing but chimneys all year. Both will take your money. The difference shows up when the repair involves a shared party-wall flue that hasn’t been inspected with a camera since the house was built, or when the problem is actually a failed liner behind intact-looking brick. That’s where local, dedicated chimney repair matters.
We’ve been in business since 2002, and our chimney repair work in Baltimore is what we do most. We don’t sub out to a mason we met last week. Our crews handle the full scope: crown repair, flashing work, tuckpointing, spalling brick replacement, flue repair, and full rebuilds where the stack is past saving.
What Sets a Real Chimney Repair Company Apart
Written pricing before work starts. A camera-backed diagnosis on any structural recommendation. A warranty that says exactly what happens if the repair fails within a year. And a tech who knows what a Baltimore rowhouse chimney stack looks like on the inside, not just from the ladder. Those four things eliminate most of the bad experiences homeowners report with chimney companies.
When a General Contractor Isn’t Enough
If your rowhouse in Canton or Fells Point has a shared stack, and the damage on your side traces back to a crown or flashing failure on your neighbor’s side, a general contractor who only works your address can’t fix the source. We quote the whole stack, coordinate with the neighbor when needed, and write the scope so both sides get repaired correctly the first time.
Trusted Brands We Service in Baltimore
We stock and install parts from Copperfield, DuraFlex, and Famco for Baltimore jobs because these are the brands that hold up to coastal humidity, freeze-thaw winters, and rowhouse flue conditions. Falkman grates and caps, Copperfield flashing, DuraFlex liners, Famco dampers: specified by job, not by margin. We carry common replacement parts in our Baltimore service vehicles so a crown repair or damper swap doesn’t wait two weeks on a shipment.
Common Chimney Repair Problems We See in Baltimore Homes
- Party-wall crown and flashing failures. In Federal Hill and Fells Point, a failed crown or rusted flashing on one side of a shared stack lets water spall the brick on both sides. Repair one address only and the damage returns next season.
- Old coal-conversion flues with no liner. Thousands of Baltimore rowhouses burned coal originally and were converted to gas or oil without ever getting a proper flue liner. Modern furnace exhaust is cooler and wetter, and it condenses into the old brick, accelerating spalling from the inside out.
- Freeze-thaw crown and cap damage. A hairline crack in October becomes a spalling mess by March. Baltimore’s January and February freeze-thaw cycles are brutal on exposed chimney masonry, especially on flat-roofed rowhouses where the stack catches full weather.
- Rusted flashing at the roofline. Three-story rowhouses in Baltimore often have original or undersized flashing that rusts through after 30 or 40 years. Leaks show up as water stains on the top-floor ceiling, but the source is usually the chimney flashing, not the roof itself.

FAQs About Chimney Repair in Baltimore
A cleaning removes creosote and soot from the flue; a repair fixes damage to the masonry, crown, flashing, or liner. If you’re seeing water stains on the ceiling below the chimney, spalled brick on the outside of the stack, or a smoke smell when the furnace runs, that’s a repair issue, not a sweeping issue. Call us at (830) 251-4560 and we’ll inspect with a camera so you know exactly what’s needed: a sweep, a repair, or both.
Yes, and here’s why: in a shared party-wall stack, water entering through a failed crown on one side doesn’t care whose address it belongs to. It tracks down through the masonry and can enter your flue, your smoke chamber, or your brick. We routinely find damage on the “good” side of a shared stack that started on the neighbor’s side. The only way to know is a camera inspection of the whole stack, both sides. Call (830) 251-4560 and we’ll check it.
Yes. Old Baltimore rowhouses often have coal-conversion flues that were never lined. Modern gas or oil furnaces exhaust cooler, wetter gases than coal did, and that can condense into creosote-like deposits that build up in an unlined flue. If the furnace is also venting into a flue shared with another unit, the risk compounds. A level-2 inspection with a camera shows whether your flue is safe. Call (830) 251-4560 for an exact quote on an inspection, estimates are free.
Third-degree creosote is a hard, glazed tar that forms when first-degree creosote is repeatedly heated and cooled without being removed. It concentrates in the flue and can’t be brushed off. It requires chemical treatment or mechanical removal, and in Baltimore’s older rowhouse flues it’s often found behind what looks like a clean chimney from the top. That’s why we camera-inspect: you can’t see the condition of the flue from the roof. If you want an exact quote on creosote removal or a liner, call (830) 251-4560.
If your chimney shows no signs of water entry, no spalled brick, no smoke smell, and the flue is lined and structurally sound, a repair can usually wait until the next regular service window. What can’t wait is any sign of water intrusion or flue damage, because Baltimore’s freeze-thaw cycles turn small problems into structural ones fast. When in doubt, we’ll tell you if it can wait, and we’ll write that in the report. Call (830) 251-4560 to schedule a free estimate.
