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.
Fast, Reliable Chimney Inspection Across Baltimore
Baltimore Chimney Inspection runs $189 – $385 for most homes, and a Level 2 camera inspection with written findings typically costs between $349 and $585, depending on whether we’re checking a single flue or multiple flues in one stack. Those numbers cover more than the inspection itself: every homeowner gets a written report with photos, a flat price before anyone climbs a ladder, and a technician whose name and photo arrive before the truck does. We know Baltimore chimneys because we work on them every week – the rowhouse stacks in Pigtown, the Formstone-fronted homes in Hampden, the older flues in Remington – and we know what goes wrong inside them. Call (336) 863-3889 to book an inspection, and you’ll know exactly what to expect before we arrive.
Why Alcott Chimney Sweep Is Baltimore’s Preferred Chimney Inspection Company
We’ve been inspecting chimneys since 2002, and the Baltimore homes we see share a problem most national franchises don’t understand: older flues inside party-wall stacks, often converted from coal or oil heat and never relined. Our Chimney Inspection team doesn’t glance at the firebox and call it done. We get on the roof, run a camera down every flue, and show you the footage before we recommend a single repair.
Baltimore homeowners keep calling us back for one reason above all: certainty. The technician’s name and photo are texted or emailed before the appointment, and every technician shows a photo ID badge at the door – no exceptions. Written price before work starts. A written guarantee on every repair, good for 365 days through our Done Right Promise. If the repair fails, the second visit is free. Those aren’t add-ons. They’re how Ruben Castellano has run every job since 2002, and they apply to every inspection we do across Baltimore.
Local Knowledge That Changes the Inspection
A street-level glance at a Baltimore rowhouse chimney can tell you almost nothing. Formstone – the molded cement facing invented here and applied to tens of thousands of rowhouses starting in the 1940s – regularly seals around the chimney base and traps moisture against original brick. We’ve seen stacks that looked intact from the sidewalk that turned out to have severe spalling hidden behind that facing. Our crews work in Pigtown, Remington, Hampden, and every corner of the city, and we plan every inspection around what Baltimore’s specific housing stock does to chimneys over decades.
Chimney Camera Inspection in Baltimore
A chimney camera inspection in Baltimore is the difference between guessing and knowing. We lower a waterproof high-resolution camera down your flue and record the full run, then sit down with you and walk through the footage. For the city’s older rowhouses – where two or three flues frequently share one brick stack, and where a gas water heater may be venting beside a wood fireplace through the same chase – this is the only way to see liner cracks, missing mortar between clay tile sections, or hidden blockages without opening up masonry. Camera inspection costs $175 – $295 when booked as part of a Level 2 inspection, and the video and written report are yours to keep. You get a copy of every image. Nothing is recommended until you’ve seen it.
What the Camera Sees
We’re looking for three things most often in Baltimore. First, cracked or separated clay tile liners, common in chimneys that were never relined after coal-to-gas conversion. Second, the separation between flues in multi-flue stacks – a breach there means exhaust from a gas appliance can migrate into the fireplace flue or, worse, the neighbor’s side of the party wall. Third, creosote buildup at the top third of the flue, where the smoke cools fastest and deposits the tar-like residue that becomes a chimney fire.
When to Request It
If you haven’t had a camera inspection in the past three years, schedule one. If you’re buying a rowhouse, do not skip it – Baltimore real estate transactions involving older homes should include a Level 2 inspection, and we’ll note that a shared party-wall flue means your chimney is part of the building, not just your house. And if a gas appliance was added to a chimney originally built for coal or oil, a camera inspection is overdue. Those flues are almost always oversized and unlined, running too cool to vent properly.
Fireplace Inspection in Baltimore
A fireplace inspection in Baltimore covers the firebox, damper, throat, smoke shelf, and the flue above it - and when gas appliances share the stack, Gas Fireplace Repair in Baltimore may be needed too – but in this city, it also needs to account for what else shares that stack. We inspect fireplaces in rowhouses where a gas water heater or furnace vents through the same brick chase, checking that each appliance has its own properly sized and intact flue path. A fireplace inspection runs $189 – $285 as a standalone, or it’s included as part of a full Level 2 when you book the camera run. Reported findings come with photos, recommendations, and a flat written price for any repairs – no pressure, no phone call two weeks later pushing a liner replacement you never saw evidence for.
Damper and Firebox Condition
On older rowhouse fireplaces, we routinely find dampers rusted open or seized entirely – Baltimore’s humidity from the Chesapeake keeps moisture in the metal almost year-round. A seized damper means you’re losing conditioned air in summer and admitting downdrafts in winter. We check the firebox mortar as well; cracked refractory panels and deteriorated joints are common in fireplaces that have seen decades of use without repointing.
Shared Flues and Gas Appliances
This is where Baltimore diverges from almost everywhere else in the country. Many renovated rowhouse fireplaces now share a chimney with a gas appliance vent someone added years ago without relining. Code requires separate, correctly sized flues for solid-fuel and gas-fuel appliances. When we find them combined, we document it on video for you, explain the carbon monoxide risk plainly, and give you a written quote for separation and relining using DuraFlex or HeatShield materials. The choice stays with you, and it’s made only with evidence in hand.
Trusted Brands We Service in Baltimore
We work with professional-grade material systems including Gelco repair in Baltimore, not box-store substitutes: DuraFlex liner systems, HeatShield resurfacing, and Olympia Chimney components. When we recommend a repair in Baltimore, we specify these brands by name in the written quote. That means you can research exactly what’s going into your chimney before you approve any work, and our crews stock the common parts locally so a liner repair or cap replacement doesn’t turn into a three-week wait for shipping.
Common Chimney Inspection Problems We See in Baltimore Homes
- Unlined or cracked clay tile flues from coal-era conversions. Many Baltimore rowhouses were built with clay tile liners sized for coal or oil heat, then switched to gas without relining. The gas exhaust runs cooler, condensation soaks into the old mortar joints, and the liner cracks from the inside out.
- Formstone sealing around the chimney base. In neighborhoods like Pigtown and Remington, the cement-asbestos facing popularized in 1940s Baltimore was often applied right up against the stack. Where it meets the chimney, moisture gets trapped against brick that can’t dry out, and spalling you can’t see from the sidewalk gets worse every freeze-thaw winter.
- Shared party-wall flues with gas and wood in the same chase. A blocked or deteriorated flue on your side of a shared rowhouse stack can push exhaust toward the neighbor’s side. We check flue-by-flue, not just from firebox to cap, because the boundary between homes doesn’t stop smoke.
- Crumbling mortar joints from freeze-thaw cycling. Baltimore’s winters don’t stay frozen for months like the Midwest’s, but that’s actually harder on brick. Water seeps in, freezes, thaws, freezes again – and each cycle pries a little more mortar loose. On a 100-year-old stack, that’s a lot of cycles.

FAQs About Chimney Inspection in Baltimore
Yes, it changes the entire scope. We treat each flue as its own system and inspect them independently, because the gas appliance needs its own correctly sized liner separate from the fireplace flue. In older Baltimore rowhouses, the two often share a single, unlined brick chase – code didn’t require separation when these homes were built. We’ll camera each flue separately, document any breach or shared path on video, and give you a written quote for separation and relining if needed. Call (336) 863-3889 and we’ll walk through what your setup looks like from the outside.
Because street-level assessment of Baltimore chimneys fails constantly. Formstone facing, and even ordinary stucco or paint, hides spalled brick and compromised mortar at the base of the stack. The crown, the cap, the top courses of brick – those are where freeze-thaw damage shows up first, and you can’t see any of it from the sidewalk. We get on the roof on every inspection that matters. If someone inspects your chimney without leaving the ground, you haven’t had an inspection; you’ve had a glance.
Expect to see damage on camera. A chimney built for coal or oil was never designed to handle the cooler, wetter exhaust from a gas appliance. Running gas through an unlined or clay-tile flue produces acid-laden condensation that soaks into the mortar joints and rots them from the inside. The flue is also oversized, so exhaust stalls instead of rising. We’ll show you the video evidence of whatever the camera finds, explain what the repair options are – HeatShield resurfacing or a DuraFlex liner are the two we specify most – and give you a written price for the fix. The decision is yours, and it’s made with evidence, not a scary speech.
It matters more, because it’s repeated instead of continuous. In a sustained deep freeze, water trapped in masonry freezes once and stays frozen. In Baltimore, we hover around the freezing point through most of the winter. That means moisture in the brick and mortar freezes one night, thaws the next afternoon, and freezes again the following week. Every cycle expands the water, widening hairline cracks into open joints. Multiply that by a hundred winters on a rowhouse stack built in 1910 and you get the deterioration we document on Baltimore inspections every week from November through March.
It can, and this is one of the least understood aspects of Baltimore rowhouse living. When two homes share a brick chase through a party wall, the flues in that chase often sit inches apart. A deteriorated flue on their side can let exhaust, moisture, or even flames migrate into your flue cavity. If the mortar between flue channels has failed, the problem crosses the property line. When we inspect your chimney, we’re checking the whole stack as it exists, not just the portion inside your walls. If we find evidence the neighbor’s side is compromised, we’ll tell you – and we’ll advise you to tell them, because waiting on a shared flue problem is never the safer option. Call (336) 863-3889 to book the camera inspection that shows you what’s actually happening in your stack.
