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.

We’ve been working on Parkville chimneys for over 42 years, and there’s something distinctive about this town: the dense blocks of postwar Cape Cods and brick ranchers built between 1945 and 1968 share chimney chases in ways newer suburbs don’t. Our crews know the tight street parking off Taylor Avenue, the narrow roof access on Harford Road’s attached homes, and the specific failure patterns that show up when one neighbor’s flue bleeds into another’s. Dispatch and scheduling are coordinated from our Baltimore office, but our technicians live and work these Parkville streets regularly.
Why Hearthstone Chimney Co. Is Parkville’s Preferred Chimney Liner & Rebuild Company
Parkville homeowners call us because we’ve seen their exact chimney before - the coal-era clay tile, the later gas conversion, the cracked crown from Baltimore County freeze-thaw cycles. We don’t guess. Our Level-2 camera inspections end with photos you can see and a plain-English verdict: what’s broken, what can wait, and what it’ll cost to fix it right.
Our reputation here is built on showing up when we say we will and standing behind the work. The 90-Day Done Right Promise means if it’s not right, we make it right - in writing, no arguing, no paperwork to chase down. Background-checked, uniformed technicians complete most liner replacements and partial rebuilds in a single visit. And when you call (410) 849-6273, a live person answers - not a voicemail, not a callback queue, not an app.
We understand Parkville’s housing stock because we’ve documented thousands of these chimneys: single-wythe brick masonry, original 4-inch or 6-inch clay tile liners, often mismatched to modern appliances. That local knowledge saves time and prevents the misdiagnoses that lead to repeat visits.
Our Chimney Liner & Rebuild Services in Parkville
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Parkville chimneys where the original clay tile has cracked or the flue is improperly sized for a gas or oil appliance. We use professional-grade DuraFlex and Olympia Chimney products - not builder-grade substitutes - and size them precisely to your appliance’s output. In Parkville’s postwar ranchers, this often means correcting a previous contractor’s undersized insert that left dangerous gaps in the flue. A properly insulated stainless liner installed by our Chimney Liner & Rebuild team restores safe draft and contains combustion byproducts where they belong.
Flexible Liner Systems
Some of Parkville’s older masonry has offsets or bends that rigid pipe can’t navigate - particularly in Cape Cods with chimney chases that shift between floors. Flexible liners from trusted manufacturers allow us to thread a complete flue system through existing masonry without destructive demolition. This matters on streets like those off Putty Hill Avenue, where homes sit close together and exterior access is tight. We’ll tell you honestly if flexible is your best path, or if the chimney’s condition calls for a different approach.
Liner Replacement
Liner replacement is our most common call in Parkville, and for good reason. The original clay tile in these 60-80-year-old chimneys has reached end of life. Cracked tiles, failed mortar joints, and efflorescence from decades of moisture intrusion are standard findings on our camera inspections. We don’t recommend replacement until we’ve shown you the photos and explained exactly what we found. When we do replace a liner, we remove the damaged material, repair the smoke chamber if needed, and install a new system sized correctly for your current appliance - not the coal furnace that was here in 1952.
Partial Chimney Rebuild
When Baltimore County’s freeze-thaw cycles have spalled brick faces and blown out mortar joints on the exterior stack, a partial rebuild restores structural integrity without the cost of tearing down the whole chimney. We rebuild from the roofline up, replacing damaged brick, repointing joints, and pouring a proper concrete crown with correct overhang and drip edge. This stops water infiltration at the source - the root cause of most liner rust and smoke chamber rot we find in Parkville homes.

Trusted Brands We Service in Parkville
We work exclusively with professional-grade materials from manufacturers who stand behind their products: DuraFlex and Olympia Chimney for stainless and flexible liner systems, HeatShield for ceramic flue repair and resurfacing, and Famco and Copperfield for caps, dampers, and ventilation components. We stock common liner diameters and fittings locally, so Parkville customers aren’t waiting weeks for parts to ship. The brands matter because a liner system is only as good as its weakest joint - and we don’t use weak joints.
Common Chimney Liner & Rebuild Problems We See in Parkville Homes
- Cross-contamination through shared party-wall chases. On Parkville’s dense postwar blocks, many brick ranchers and Cape Cods share a chimney chase with the neighbor’s flue. A failed mortar joint or unsealed annular gap on one side lets carbon monoxide and creosote odor migrate into the next house - a problem the homeowner can’t diagnose without a camera inspection that examines both sides of the stack.
- Coal-era flues mismatched to gas conversions. The original oversized clay tile - often 8-inch in Parkville’s ranchers - was later fitted with a smaller gas insert liner without proper resizing or sealing. That annular gap between old tile and new metal becomes a hidden reservoir for condensation, carbon monoxide, and creosote byproducts. We’ve found this exact failure mode on multiple homes on the same street.
- Freeze-thaw destruction of exterior masonry. Parkville sits far enough inland from the Chesapeake Bay to get little thermal moderation, so winter temperatures cross 32°F dozens of times per season. Each cycle drives moisture deeper into single-wythe brick, spalling faces and blowing mortar joints until the crown cracks and water enters the flue system from above.
- Rusted liners from top-down water intrusion. Once the crown or flashing fails, water runs down the flue, rusting stainless or aluminum liners and rotting the smoke chamber mortar from the top down. By the time a homeowner notices staining on the basement cleanout door, the damage has been progressing for multiple seasons.

FAQs - Chimney Liner & Rebuild in Parkville
Yes, and this is one of the most underdiagnosed hazards in Parkville’s postwar housing. When two flues share a chimney chase and a mortar joint cracks or an annular gap opens, carbon monoxide and combustion odors can migrate from one side to the other. Our Level-2 camera inspection examines both flues in the shared stack and documents any crossover points with photos you can see. If we find a breach, we seal it properly - not with guesswork, but with materials and methods rated for multi-flue chimneys. Call (410) 849-6273 to schedule an inspection if you smell anything unusual when either appliance runs.
The most common cause is an annular gap between original oversized clay tile and a later, undersized gas insert liner. That gap traps creosote and condensation; when the furnace or water heater cycles, pressure changes push odor into your living space. We’ve found this exact pattern repeatedly on Parkville’s same-vintage streets - it’s a signature failure of coal-to-gas conversions done without proper resizing. A camera inspection confirms it in minutes, and a correctly sized, insulated liner replacement eliminates it permanently. Call (410) 849-6273 for an exact diagnosis - estimates are free.
A partial rebuild is appropriate when damage is limited to the exterior stack above the roofline - spalled brick, failed mortar, cracked crown - while the interior flue and smoke chamber remain structurally sound. We determine this with a camera inspection and physical probe of the masonry. A full rebuild becomes necessary when damage extends below the roofline, when the foundation or footing has shifted, or when multiple flues are compromised throughout their height. We’ll show you the photos and explain which category your chimney falls into, with no pressure to commit to more work than the condition warrants. Call (410) 849-6273 to get the full picture.
Most do, but some require modification. The original 4-inch or 6-inch clay tile flue in Parkville’s Cape Cods and ranchers typically provides adequate clearance for a properly sized stainless liner once damaged tile is removed. Where the flue is too narrow or has excessive offsets, we may need to gently enlarge the passageway or use a flexible liner system. We measure and photograph every flue before ordering materials - no liner goes in until we’ve confirmed it fits and drafts correctly for your specific appliance. Call (410) 849-6273 and we’ll assess your chimney’s dimensions.
One winter won’t destroy a sound liner, but it accelerates damage that’s already started. When water enters through a cracked crown or failed flashing, each freeze-thaw cycle expands that moisture by about 9%, progressively spalling brick and opening mortar joints. For metal liners, the real damage is rust from sustained moisture contact - not the cold itself. In Parkville’s inland climate, with dozens of freeze-thaw crossings per season, a leaking chimney crown can turn a repairable liner into a replacement in a single winter. The fix is stopping water at the top: crown, flashing, and cap. Call (410) 849-6273 for an inspection before the next cold season.
