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.

Why Alcott Chimney Sweep Is Baltimore Highlands’s Preferred Chimney Sweep Company
Alcott Chimney Sweep has built its reputation in Baltimore Highlands on something most chimney companies never think to offer: proof of who’s coming before they arrive. When you book a sweep in Baltimore Highlands, you’ll get the technician’s name and photo sent to you ahead of time. That person is background-checked, identity-verified, and required to show a photo ID badge at your door. Every time. Ruben Castellano set that standard because he knows that in a community of attached homes, letting a stranger into your house is a bigger decision than it is in a detached suburb.
Our team also understands the specific housing stock here better than out-of-town companies. We know that a 1930s semi-detached rowhouse near the city line has different chimney problems than a 1980s home in Ellicott City. When we inspect a flue in Baltimore Highlands, we’re checking for the things that actually fail here: spalled clay tile, eroded crown mortar, and gas appliances in shared stacks. Every job gets a written price before work starts. No exceptions, and no surprises on the invoice.
Fireplace Cleaning in Baltimore Highlands
Fireplace Cleaning in Baltimore Highlands isn’t just about removing ash from the firebox. It means removing the soot and creosote, the tar-like buildup that causes chimney fires, from the full length of the flue, smoke shelf, and damper assembly. For most Baltimore Highlands homes, we recommend a fireplace cleaning any time you’ve burned more than a cord of wood since the last sweep, or at minimum once per year before burning season starts. A fireplace cleaning in Baltimore Highlands typically runs $189 – $249, depending on the condition of the flue and how much creosote has accumulated.
What We Remove and Why It Matters
Creosote builds up in layers. First-degree is flaky and can be brushed out. Third-degree is a hard, glazed tar that bonds to the flue wall and requires chemical treatment or mechanical removal. In Baltimore Highlands, we frequently see third-degree creosote in chimneys that were converted from coal to wood without a proper lining upgrade. That’s a fire waiting for a spark.
Annual Maintenance Saves Repairs
An annual fireplace cleaning lets us catch hairline cracks in clay tiles before they widen into a relining job. In a 90-year-old Baltimore Highlands chimney, those hairline cracks are common. Catching them early keeps a $200 cleaning from becoming a $3,500 liner replacement.
Chimney Services in Baltimore Highlands
Chimney Services in Baltimore Highlands go beyond the basic sweep. We provide Level 1 and Level 2 inspections, creosote removal, soot removal, and full fireplace cleanings, and each service is designed for the specific way homes were built here. A Level 2 inspection in Baltimore Highlands typically runs $249 – $399 and includes camera access to the full flue, smoke chamber, and firebox. If you’re buying or selling a home in Baltimore Highlands, Baltimore County requires a Level 2 inspection before the certificate of occupancy can close. That’s a county rule, not a city one, and a lot of homeowners near the city line get that wrong.
Level 1 vs. Level 2: Which One You Need
A Level 1 inspection is visual and covers the accessible portions of the chimney. We do it as part of every annual sweep. A Level 2 adds camera inspection and is required for real estate transactions, after a chimney fire, or when a gas appliance is added to an existing flue. If you share a stack with a neighbor, we recommend a Level 2 even if you’re not selling, because the camera catches cross-vent connections you can’t see from the ground.

Gas Appliance Venting in Shared Stacks
This is the issue we run into most in Baltimore Highlands. A neighbor’s gas furnace or water heater gets vented into a brick stack that also serves your gas fireplace. Without a properly sized liner on both sides, exhaust gases can migrate into your flue, your smoke chamber, and eventually your living space. It’s not just a draft problem. It’s a carbon monoxide risk, and it requires a liner that’s sized for the specific appliance, not the original coal firebox. We install DuraFlex liner systems for exactly this condition.

Trusted Brands We Service in Baltimore Highlands
We don’t use box-store parts in Baltimore Highlands chimneys. We carry and install professional trade materials from DuraFlex, Olympia Chimney, and Famco because those brands are specified by chimney professionals and built to handle the moisture, freeze-thaw stress, and gas appliance venting common to this area. When a Baltimore Highlands homeowner needs a liner, a crown repair, or a new cap, we can usually have the right parts on the truck the first visit. That means less waiting between diagnosis and fix, and less exposure for a flue that’s already failing.
Common Chimney Sweep Problems We See in Baltimore Highlands Homes
- Shared stacks with cross-vented gas appliances. In semi-detached rowhouses built in the 1930s, a neighbor’s gas furnace often vents into the same stack as your fireplace. If neither side has a proper liner, exhaust gases move between flues. We’ve documented this with camera inspections on multiple blocks in Baltimore Highlands.
- Spalled clay tile in 70 – 100-year-old flues. The original clay tiles in these chimneys have endured 90+ freeze-thaw cycles per year since the 1920s. The Patapsco River moisture accelerates the breakdown. Cracked tile fragments can block the flue and expose the brick wall to direct heat.
- Eroded crown mortar and failed flashing at the roofline. Baltimore Highlands gets more ambient moisture than drier inland parts of Maryland. That moisture seeps into crown mortar joints during freeze cycles, then the ice expands and pops the mortar loose. Most roofline damage we see here started years before anyone noticed a leak.
- Coal-era fireboxes bricked up and converted without lining. A lot of Baltimore Highlands homes had their coal fireboxes sealed and a gas insert added decades ago, with no flue liner installed. It looks finished from the roofline. It fails a camera inspection. Baltimore County code requires the liner to be installed before a sale closes.

FAQs About Chimney Sweep in Baltimore Highlands
Yes, a sweep can identify it and, in most cases, correct it. Shared stacks are common in Baltimore Highlands semi-detached rowhouses, and when a neighbor’s gas furnace vents into the same stack as your fireplace, exhaust can cross into your flue if the liners are missing or improperly sized. We use a Level 2 camera inspection to document the cross-vent, then install an appropriately sized liner, typically DuraFlex, on your side. Baltimore County code governs this correction, and the county requires it before a sale can close. Call (336) 863-3889 and we’ll walk you through what the inspection involves, or our Chimney Sweep team can come out and take a look.
You’ll know from a Level 2 inspection, which Baltimore County requires in Baltimore Highlands before a certificate of occupancy or sale can close. The inspector will look for three specific failure points: spalled clay tile fragments in the flue, missing or deteriorated mortar joints between tiles, and any gas appliance venting that was added without a liner. If any of those conditions exist, you’ll need a liner installed before closing. In our experience, the majority of 1920s – 1940s rowhomes in Baltimore Highlands that haven’t had a liner upgrade fail the inspection. Call (336) 863-3889 for a Level 2 quote, and we’ll give you the camera report on the spot.
Because Baltimore Highlands sits close to the Patapsco River, and the ambient moisture from the river corridor combines with the area’s 90+ freeze-thaw cycles per year. Water soaks into the crown mortar and flashing seals, then each freeze cycle expands the ice and breaks the bond a little further. Over a few winters, the crown crumbles and flashing pulls away from the brick. That’s why we recommend an annual inspection in Baltimore Highlands, not every other year. By the time you see a stain on the ceiling, the crown has usually been failing for two or three seasons.
A Level 1 inspection is visual and covers the accessible parts of the chimney. It’s included with an annual sweep. A Level 2 adds a camera and is required for real estate transactions, after a chimney fire, or whenever a gas appliance is added to a flue; in Baltimore Highlands, most sales require a Level 2 because of Baltimore County code. A Level 3 inspection involves removing portions of the chimney structure to access concealed areas, typically after a known fire or structural failure. Most Baltimore Highlands homeowners never need a Level 3, but if you do, we’ll tell you exactly why and what it costs before we touch a brick. Call (336) 863-3889 for an honest recommendation.
Third-degree creosote can usually be removed without a rebuild, but it depends on how thick the glaze is and whether the underlying clay tile has already failed. We use mechanical and chemical removal methods designed for glazed creosote, and we follow with a camera inspection to check the condition of the flue behind it. In Baltimore Highlands, we often find that third-degree creosote has been building on top of spalled tile for years, which means the flue needs a liner even after the creosote is gone. The creosote removal itself typically runs $350 – $650. If the tile is bad, a DuraFlex liner is the right fix. Call (336) 863-3889 and we’ll give you a written price before we start, including the liner if you need it.
