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.

AfterChimney Company in Baltimore, MD
A chimney company in Baltimore has to know rowhouses. Around 70,000 brick rowhomes, most built between the 1880s and 1940s, share party walls and multi-flue stacks that don’t behave like the chimneys on detached homes in the counties. Freeze-thaw cycling off the Chesapeake keeps mortar joints working loose, and plenty of those original clay liners were never upgraded when coal heat gave way to gas. We’re Alcott Chimney Sweep, and we handle sweep, inspection, and gas fireplace work in Baltimore with written pricing before any job starts. Call (336) 863-3889 and a live person answers.
Why Baltimore Homes Are Different
Most Baltimore chimneys run through the interior of the house, not up an outside wall. That means a failing flue liner isn’t just a chimney problem, it’s a carbon monoxide problem for every floor between the appliance and the roof. A big share of these homes were switched from coal or oil to gas without relining, and the old clay tile was sized for an open hearth, not a modern gas appliance. Oversized, unlined flues cool exhaust too quickly, which causes condensate, which eats mortar from the inside.
Then there’s the weather. Baltimore doesn’t get the long deep freeze of the Midwest, but the repeated freeze-thaw cycles we do get are worse for brick. Water gets into a hairline crack, freezes, expands, thaws, and repeats that cycle dozens of times each winter. After 80 to 140 years, spalled brick faces and crumbling crowns are common, especially in neighborhoods like Hampden, Remington, and Pigtown where home maintenance varied widely by block. What looks sound from the sidewalk often isn’t once you’re on the roof.
Our Main Baltimore Services
Baltimore homeowners call us most often for two things: getting a flue clean before burning season, and figuring out whether an old rowhouse stack is safe to keep using. Every quote is written and in your hand before work begins.
Chimney Sweep in Baltimore
A standard sweep here often turns up more than creosote, which is the tar-like buildup that causes chimney fires. We routinely find gas appliance vents sharing the same brick chase as a wood-burning fireplace, a rowhouse condition that needs a close look at separation and liner condition. Baltimore’s shared party walls mean a blocked flue in one home can affect exhaust in the one next door. We show up with commercial equipment, leave the hearth cleaner than we found it, and hand you a written report on what we saw. Full details on the Chimney Sweep in Baltimore page.
Chimney Inspection in Baltimore
For rowhouses, we recommend a camera inspection whenever a property changes hands or when an old stack is being brought back into service after years of dormancy. The camera shows you exactly what’s inside the flue: cracked tiles, missing mortar, voids behind the brick, and whether a gas flue is venting into a correctly sized passage. If Formstone or any other facing has sealed around the chimney base, what’s visible from the ground tells you almost nothing about the condition underneath. That’s a common Baltimore scenario. Details are on the Chimney Inspection in Baltimore page.
Gas Fireplace Repair in Baltimore
Gas fireplaces in older Baltimore homes are often retrofit units installed into what used to be a wood-burning hearth, and the venting route matters. A unit that worked fine for years can start shutting down or throwing error codes when the flue it shares with an old coal chase corrodes or fills with debris. We service vented and vent-free units, replace thermocouples, igniters, and gas valves, and we use trade-spec parts from Gas Fireplace Repair in Baltimore suppliers, not box-store substitutes. If a gas repair isn’t right, our written guarantee brings us back free.

Pricing for Chimney Company in Baltimore, MD
These are the ranges we quote most often in Baltimore. Prices are written before work starts, and nothing gets added at the end.
| Service | Typical range in Baltimore |
|---|---|
| Standard chimney sweep (wood-burning, accessible roof) | $180 – $340 |
| Chimney sweep with animal or debris removal | $240 – $450 |
| Level 1 visual inspection (no special tools, often bundled with a sweep) | $90 – $160 |
| Level 2 camera inspection (real estate, appliance change, or after a chimney fire) | $250 – $550 |
| Chimney cap supply and install (basic single-flue) | $240 – $600 |
| Damper replacement (top-sealing or throat-mount) | $250 – $700 |
| Minor crown repair / sealing | $300 – $800 |
| Flue resurfacing with HeatShield (single flue) | $1,900 – $3,500 |
| Full stainless liner install (DuraFlex or similar) | $2,900 – $5,800 |
What pushes a Baltimore quote toward the top of those ranges is usually roof access. Steep rowhouse roofs with shallow pitch and tight alleys, or a stack on a party wall that needs a 40-foot ladder and roof anchors, take longer. What never changes is the pricing rule: you get a written number before we touch anything, and that number is the number.

FAQs About Chimney Company in Baltimore
No. Routine sweeping, inspection, and most liner repairs are maintenance work that doesn’t require a city permit. Only structural changes like rebuilding a stack or adding a new flue opening would need to go through Baltimore’s permitting office, and we’d flag that with you before any of that work begins. Call us at (336) 863-3889 if you want to know where your job falls.
Most sweeps and inspections get scheduled within a week. We route Baltimore jobs by neighborhood, so if you’re in Hampden or Pigtown and we already have a crew in the area, it can often be sooner. You’ll know your technician’s name and see their photo before the appointment.
Yes, constantly. Party-wall stacks are standard in Baltimore rowhouses, and we treat a multi-flue stack as one system, not as two separate chimneys. If we see deterioration that affects the neighboring home, we’ll document it and tell you plainly what’s yours to fix and what likely needs a conversation with the other owner. Call (336) 863-3889 to talk it through.

What Baltimore Customers Say
"Water was leaking around the flashing. They resealed it and installed a new crown coating. Dry through two heavy rains since."
- Douglas P."Fast and tidy. Fireplace draws properly again."
- Mina K."Good chimney cleaning. They found a small gap in the mortar and quoted the repair, which was a bit more than I wanted to spend. Did the sweep and left the repair for later without any pressure."
