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.

What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, properly matched mortar into the joints. In Owings Mills, we regularly see mortar crumble after fifteen to twenty winters of freeze-thaw cycling, especially on chimneys exposed to northwest winds off the Piedmont. Our technicians use professional-grade mortar mixes and color-match to your existing joints so the repair disappears into the wall.
Spalling Brick Repair
Spalling happens when water trapped inside bricks freezes, expands, and flakes the face right off the brick. You’ll notice this as rough, pitted surfaces or actual chunks missing from your chimney exterior. We remove spalled bricks and install matching replacements, or when the damage is surface-level, we apply specialized resurfacing compounds that seal and protect what’s left.
Chimney Waterproofing
Waterproofing is the preventive treatment that stops spalling and mortar decay before they start. We apply vapor-permeable sealers from professional-grade suppliers that let brick breathe while blocking liquid water. In the humid summers and wet winters around Owings Mills, this treatment typically extends chimney life by a decade or more, and we always recommend it after any major masonry repair.
Flashing Repair
Flashing is the metal barrier where your chimney meets the roofline, and it’s the single most common leak point we find in Owings Mills homes. Our technicians lift shingles carefully, remove corroded or improperly installed flashing, and install new copper or galvanized steel flashing with proper step and counterflashing integration. We finish with a water test so you know the seal is solid before we leave.
Chimney Rebuilding
When deterioration has compromised structural integrity - leaning stacks, widespread spalling, or separated courses - partial or full rebuilding is the only safe option. We dismantle only what’s necessary, salvage reusable brick when possible, and rebuild to current Baltimore County code with proper liners, caps, and crown integration. Every rebuild includes photo documentation at each stage and a final inspection with the homeowner.
Tuckpointing
Tuckpointing is the cosmetic and structural restoration of mortar joints, often on older or historic chimneys where appearance matters as much as function. We cut joints to uniform depth, pack them with base mortar, then apply a thin contrasting line to create the classic fine-joint appearance. In neighborhoods like Lutherville and Cockeysville with stone farmhouses and early colonial revivals, this detail preserves architectural character while sealing out water.

Brands We Service for Chimney Repair
We’ve installed and repaired thousands of Gelco chimney caps and dampers across Baltimore County. Their stainless steel and copper caps hold up to our coastal-plain humidity better than the galvanized hardware-store versions that rust through in five years. We stock common Gelco sizes and can order custom dimensions for oversized or unusual flue configurations.
Olympia Chimney’s flexible stainless liners and Famco’s ventilation accessories are regular items on our trucks. We’ve run Olympia liners up flues with offset bends that other companies walked away from, and we’ve solved draft problems in Owings Mills split-levels using Famco’s specialized termination caps. Whether you have Gelco, Olympia Chimney, Famco, or any other make, we can help. Our warehouse carries Copperfield refractory panels and repair mixes for firebox restoration, and we source HeatShield cerfractory resurfacing products for flue liner repair without full replacement.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on brick or mortar. This powdery deposit means water is moving through your masonry, dissolving salts, and depositing them on the surface. It’s not just cosmetic - it’s evidence of internal moisture damage that will accelerate mortar decay and brick spalling through each freeze-thaw cycle.
- Cracked or missing mortar joints. Gaps between bricks let water pour straight into the wall structure. In Owings Mills, we’ve seen unchecked joint deterioration lead to chimney lean within three to five years, and a leaning chimney is a full rebuild, not a repointing job.
- Water stains on ceilings or walls near the fireplace. This almost always traces to failed flashing, cracked crown, or deteriorated mortar letting water run down the flue and into your framing. The longer it continues, the more extensive the interior damage becomes.
- Chunks of brick or mortar in your yard or at the chimney base. Spalling has progressed to the point where material is falling away. This is structural compromise, not surface weathering, and it won’t stop until the affected bricks are replaced or resurfaced.
- Your chimney crown is cracked or crumbling. The concrete crown is your chimney’s umbrella. Once water gets past it, the freeze-thaw destruction of everything below accelerates dramatically. Crown repair or replacement is straightforward; rebuilding the chimney below it is not.

How Much Does Chimney Repair Cost in Owings Mills?
A typical mortar repointing job on a standard single-flue chimney in Owings Mills runs $850-$1,800 depending on how many courses need attention and whether scaffolding is required for height access, and you can learn more about how much Chimney Repair costs below. Spalling brick repair on localized damage starts around $650 and can reach $2,400 if multiple faces need replacement across several courses. Flashing repair generally falls between $450 and $1,200, with copper flashing at the higher end and galvanized steel toward the lower. Full chimney rebuilding, when necessary, ranges from $4,500 to $12,000 depending on height, brick matching requirements, and whether liner replacement is included.
What moves the price? Accessibility is the big variable. A chimney on a walkable roof with clear ladder access costs less than one requiring scaffolding or boom equipment. Material matching matters too - finding brick that blends with 1970s Owings Mills construction takes more sourcing effort than standard modular brick. The extent of hidden damage we discover after opening the wall is the third factor, which is exactly why we perform camera inspection before quoting and show you the evidence.
How to avoid overpaying: get a second opinion on any estimate over $1,500. Hearthstone Chimney Co. provides free second opinions on any written estimate - bring us the paperwork and we’ll review it honestly. Also, beware the low bid that doesn’t include liner inspection or crown assessment; we’ve been called in after cut-rate repointing failed because the underlying water source was never addressed. Our estimates include everything needed to solve the problem, not just patch the symptom.
What’s included in our free estimate: full exterior inspection, Level-2 interior camera evaluation, digital photos with annotated notes, a written scope of work, and firm pricing valid for 30 days. Call (443) 998-2617 to schedule - estimates are free, and there’s no obligation to proceed.

Active water intrusion, leaning chimneys, and fallen bricks require prompt attention to prevent structural or interior damage. We don’t use scare tactics, but we also won’t minimize genuine hazards - a separated chimney stack can damage your roof in high winds, and water running into wall cavities breeds mold.

Our technicians bring drop cloths and vacuum equipment, but a little preparation on your end keeps things moving. We’ll confirm any specific needs when we schedule, and we don’t require you to be home for exterior-only work if you prefer to run errands.
