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 Baltimore Highlands chimneys long enough to know the difference between a house on Annapolis Road and one closer to the city line. The brick semi-detached homes built here from the 1920s through the 1950s weren’t designed for today’s heating appliances. Coal flues got converted to oil, then gas, then wood stoves, and the clay tile liners stayed the wrong size through every conversion. That’s not a guess. We pull those liners and photograph them on nearly every job.
Why Hearthstone Chimney Co. Is Baltimore Highlands’s Preferred Chimney Repair Company
Baltimore Highlands sits in unincorporated Baltimore County, blocks from the Baltimore City line, and that distinction matters more than most homeowners realize. Out-of-area contractors routinely apply city permit rules to county properties, leaving repairs unpermitted and flues non-compliant. We’ve corrected that mistake more than once after another company finished work that couldn’t pass county inspection. Our technicians know Baltimore County’s requirements by heart, and we pull permits correctly the first time.
Our 90-Day Done Right Promise governs every repair in Baltimore Highlands: in writing, no arguing. If it’s not right, we come back. That’s been our standard for over 42 years, since Russell Haines founded the company in 1984. Background-checked, uniformed technicians arrive with DuraFlex, HeatShield, and Gelco materials on the truck, so most Baltimore Highlands jobs finish in one visit. No-hassle upfront pricing means the estimate number matches the invoice number.
A homeowner on Annapolis Road in Baltimore Highlands was running a wood stove as primary heat in their 1948 brick semi-detached, and when we pulled the pipe we found third-degree creosote glazing the flue liner plus two cracked clay tiles from freeze-thaw. We installed a HeatShield liner to the correct diameter for the stove, repointed the spalled mortar joints, and rebuilt the chimney crown - their draft improved immediately and the next sweep came back first-degree only.

Our Chimney Repair Services in Baltimore Highlands
Mortar Repointing
Baltimore Highlands’s 20-30 annual freeze-thaw cycles grind away at mortar joints faster than homeowners notice. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar rated for mid-Atlantic conditions. On a typical Baltimore Highlands semi-detached near the county line, we expect to repoint 15-30 linear feet of joint on a chimney that’s never had maintenance. Done right, and we stand behind it.
Spalling Brick Repair
Spalling - brick faces popping off from freeze-thaw moisture penetration - is routine in Baltimore Highlands chimneys that vent gas appliances into oversized coal-era flues. The condensation runs back down, saturates the brick, and winter does the rest. We remove spalled brick, match replacement units, and address the moisture source so it doesn’t repeat. Photos you can see, a plain-English verdict.
Chimney Waterproofing
Summer humidity from the Chesapeake Bay watershed keeps Baltimore Highlands chimneys damp even in July. We apply vapor-permeable waterproofing agents that let the masonry breathe while blocking liquid water, critical for chimneys that sit idle six months between heating seasons. Waterproofing a Baltimore Highlands chimney typically runs $350-$650 depending on accessible surface area.
Flashing Repair
The junction where chimney meets roof takes a beating in Baltimore Highlands, with thermal expansion cycling through those same freeze-thaw winters. We fabricate custom flashing or install pre-formed systems from Olympia Chimney, sealed with professional-grade compounds. A square deal: no surprises on the bill.
Chimney Rebuilding
When mortar loss exceeds 30% or structural integrity is compromised, partial or full rebuilding becomes the honest recommendation. In Baltimore Highlands, we most often rebuild from the roofline up on 1940s semi-detached homes where the upper chimney has taken the worst weather exposure. Rebuilding with matching brick and proper crown construction typically runs $2,800-$4,500. We’ll show you the photos and explain exactly why rebuilding beats continued patching.
Tuckpointing
For Baltimore Highlands homeowners who want the aesthetic match of historic mortar profiles, tuckpointing recreates the fine joint lines of original construction. It’s slower work than standard repointing, but on a 1920s row or semi-detached where appearance matters, the result preserves the home’s character while sealing out water.

Common Chimney Repair Problems We See in Baltimore Highlands Homes
- Coal-era flues converted to wood stoves without resizing. The undersized clay tile builds dense creosote fast, and the shorter safe sweeping interval gets ignored until the inspector or a chimney fire forces attention. We measure, photograph, and specify the correct liner diameter for the appliance.
- Freeze-thaw cycles crack mortar joints and clay tiles. Baltimore Highlands’s 20-30 annual cycles let moisture into the smoke chamber and firebox, which then spalls brick from the inside out between heating seasons. We catch it with Level-2 camera inspection before the face falls off.
- Contractors applying Baltimore City rules to county properties. Baltimore Highlands is unincorporated Baltimore County, and chimney work here requires county permits and inspections. We’ve seen out-of-area contractors finish entire rebuilds only to have the homeowner discover nothing was permitted.
- Shared furnace and fireplace flues in semi-detached homes. A 1940s brick semi-detached on Annapolis Road or near the Lansdowne border often has one chimney serving both a furnace flue and a fireplace flue. That’s no longer code-compliant for many configurations, and we document exactly what separation or relining is required.

FAQs - Chimney Repair in Baltimore Highlands
Wood stove chimneys in Baltimore Highlands should be swept every 50-60 burns or annually, whichever comes first, and more frequently if you’re burning unseasoned wood or running the stove as primary heat. The coal-era flues common here are often undersized for modern stoves, which accelerates creosote buildup past what a standard fireplace schedule allows. Call (410) 849-6273 to schedule - we’ll inspect the liner diameter and burning practice while we’re there.
Yes, structural chimney repairs in unincorporated Baltimore County require a permit and inspection, and Baltimore Highlands falls under county jurisdiction despite sitting blocks from the city line. Many out-of-area contractors mistakenly apply Baltimore City rules, leaving work unpermitted and non-compliant. We pull Baltimore County permits correctly on every qualifying job, and the inspection is included in our process.
Shared flues are generally no longer code-compliant for solid-fuel appliances, though some gas configurations may be grandfathered depending on Baltimore County’s current interpretation. We run a camera to determine exactly what shares what, then document whether separation or relining is required for safe operation. The inspection findings are yours to keep, and we’ll tell you plainly if the fireplace can stay in service as-is.
Baltimore Highlands’s 20-30 annual freeze-thaw cycles force moisture trapped in masonry to expand and contract, grinding away mortar joints from the inside. Summer humidity from the Chesapeake Bay watershed keeps chimneys damp year-round, so there’s always moisture available when winter arrives. Proper repointing with mid-Atlantic-grade mortar, combined with crown repair and waterproofing, breaks that cycle. Call (410) 849-6273 for an inspection - estimates are free.
First-degree creosote is dry, flaky soot that brushes off easily during standard sweeping. Third-degree creosote is hardened, glazed, and tar-like, often requiring chemical treatment or rotary removal, and it presents the highest chimney fire risk. The homeowner on Annapolis Road we mentioned earlier went from third-degree to first-degree after we installed a properly sized HeatShield liner and corrected their burning practice. If you’re seeing shiny black buildup or hearing a crackling sound when the stove runs, call (410) 849-6273 - that’s not a wait-and-see situation.
