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.

AfterFast, Reliable Chimney Cap & Crown Across Lutherville
Chimney cap and crown work in Lutherville runs $280-$1,200 depending on whether you need a standard cap installation, crown coating, or a custom multi-flue cap on a historic shared stack. Most jobs are completed in a single visit after a Level-2 camera inspection confirms what your chimney actually needs. Call (410) 849-6273 and a live person will pick up, 24 hours a day.
We’ve been dispatching crews from our Baltimore office into Lutherville for decades. We know the difference between a 1970s colonial off York Road and an original 1852-grid cottage near the historic district, and we know that a cap job on the latter is rarely just about keeping rain out. Our Chimney Cap & Crown team carries the equipment to handle shared stacks, unlined flues, and the Baltimore County code problems they create.
Why Hearthstone Chimney Co. Is Lutherville’s Preferred Chimney Cap & Crown Company

Our technicians are background-checked, uniformed, and trained to spot what price-cutting sweeps miss: the adjacent flue in your shared stack, the missing liner you didn’t know about, the crown that’s too far gone for a cap to save it. Most jobs finish in one visit. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice.

Our Chimney Cap & Crown Services in Lutherville
Cap Installation
A proper cap on a Lutherville chimney is your first defense against the 20-plus inches of snow and freeze-thaw cycles Baltimore County sees each winter. On mid-century ranches and colonials off York Road, we install Gelco and Famco caps with stainless steel mesh to stop water, animals, and debris while letting smoke vent freely. We measure your flue precisely and bolt the cap to a sound crown, not to crumbling mortar that’ll fail by spring.
Cap Replacement
Caps rust, blow off in wind, or get installed wrong from the start. In Lutherville, we replace builder-grade caps that were never sized correctly for the flue, especially on 1950s-1970s housing where the original cap was an afterthought. We remove the old unit, inspect the crown beneath it, and fit a replacement that actually matches your flue count and dimensions. If the crown is shot, we’ll tell you before we bolt anything down.
Crown Repair
The crown is the concrete or mortar slab that seals the top of your chimney between the flue tiles. On Lutherville’s original 1852-grid cottages, these were often a thin wash of mortar with no overhang, no reinforcement, and no chance of surviving 170 years of freeze-thaw. We grind out the damaged material and pour a proper cementitious crown with correct slope and drip edge, or apply HeatShield crown coating when the structure is sound but the surface is cracked. A cap bolted to a bad crown just traps water and rusts out within a season.
Crown Coating
For crowns with minor cracking but solid structure, we apply HeatShield crown coating, a professional-grade refractory compound that seals hairline fractures and restores water shedding. This is often the right call on Lutherville’s mid-century homes where the crown was built to code but has aged past its service life. We don’t coat over spalling concrete or structural failure; we photograph the damage, show you, and recommend repair or rebuild if that’s what your chimney needs. Done right, crown coating adds years of life at a fraction of full replacement cost.
Multi-Flue Cap
On Lutherville’s dense 1852-grid housing, multi-flue caps are not optional. When two or more flues share a single chimney stack, a cap that covers only your flue leaves your neighbor’s exposed to the same rain and snow, and leaves you exposed to cross-contamination when wind-driven draft pushes combustion gases between unlined flues. We fabricate and install custom multi-flue caps from Copperfield and Olympia Chimney that shelter the entire stack, with proper clearance and mesh for each flue. This is specialized work. We measure on site, account for slope and flue spacing, and bolt to a rebuilt or coated crown that can carry the load.
Custom Cap
Historic Lutherville chimneys were not built to standard dimensions. Flues are offset, crowns are irregular, and the stock cap from a hardware store won’t fit or function. We measure, fabricate, and install custom caps in stainless steel or copper, sized to your exact chimney top. Our custom work uses professional-grade materials from Gelco and Copperfield, not thin-gauge substitutes that dent in the first hailstorm. Every custom cap ships with our 90-Day Done Right Promise.

These are the brands we trust on our own homes, and they’re the brands we bring to yours in Lutherville. Because we carry inventory locally, most cap and crown jobs don’t wait on shipping.

Common Chimney Cap & Crown Problems We See in Lutherville Homes
- Shared-stack cross-contamination on the 1852 grid. A cap sized for one flue on a two-flue stack does nothing to stop your neighbor’s gas appliance from pushing carbon monoxide through the unlined brick between you. We find this regularly on attached cottages where the homeowner called for water damage and we found a code violation.
- Crown failure behind a “good enough” cap. Homeowners in Lutherville’s historic district bolt a new cap onto a crown that was thin mortar from the start. Water gets behind the flashing, freezes, and pushes the cap off within two winters. We crown first, cap second.
- Spalled brick from rain intrusion on unlined flues. Without a liner, water that gets past a damaged cap soaks directly into soft historic brick. Each freeze-thaw cycle pops off another layer. By the time you see interior water stains, the cap has been failing for years.
- Wrong cap for a converted flue. A Lutherville chimney converted from wood to gas needs a cap with proper draft clearance and corrosion-resistant mesh. A wood-burning cap on a gas flue can restrict venting and create a condensation trap that rots the flue from the inside.

FAQs - Chimney Cap & Crown in Lutherville
No. A standard single-flue cap leaves your neighbor’s flue exposed and does nothing to stop cross-contamination between unlined flues in the same stack. We install multi-flue caps that cover the entire chimney top, with proper mesh and clearance for each flue, and we inspect both flues before recommending a solution. Call (410) 849-6273 and we’ll assess your shared stack on site.
Because the original crown was a thin mortar wash with no structural reinforcement, no overhang, and no defense against 170 years of freeze-thaw cycling. Patching adds material but doesn’t fix the design. We grind out the failed crown and pour a proper cementitious crown with slope, drip edge, and reinforcement, or apply HeatShield coating if the structure beneath is sound. A cap alone won’t save a crown that was never built to last.
Yes. Bare brick flues serving gas appliances violate Baltimore County code and create carbon monoxide risk. This is common on Lutherville’s 1852-grid cottages, where chimneys were built for seasonal wood fires and never lined. A cap or crown job becomes a relining conversation when we find this, and we document it with camera photos you can see before any work proceeds. We don’t cover up code violations with a cap.
Baltimore County’s 20-plus inches of annual snow plus repeated thaw events aggressively spalls soft historic brick and erodes lime mortar. If your crown has cracks wider than a hairline, or if water is pooling on top, coating or full repair is necessary before any cap installation. A new cap on a failing crown traps moisture and accelerates damage. We inspect, photograph, and tell you which category you’re in before quoting.
We require it on any chimney built before 1980, and we strongly recommend it on all Lutherville work given the prevalence of unlined flues and shared stacks. The Level-2 inspection uses a camera to document flue condition, liner presence, and structural integrity. You get photos and a plain-English verdict. No cap or crown goes on until we know what we’re covering. Call (410) 849-6273 to schedule; estimates are free.
