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.

Chimney Repair in Towson typically costs between $350 and $4,500 depending on the scope, with most standard repairs like mortar repointing or flashing work falling in the $800-$2,200 range. Hearthstone Chimney Co. has been repairing chimneys in Towson and surrounding Baltimore County communities for over 42 years, and we complete most jobs in a single visit with no-hassle upfront pricing. Call (443) 785-3816 to speak with a live person any time, day or night.
Towson’s freeze-thaw cycles do real damage to masonry. Water gets into hairline cracks in October, freezes by January, and opens those cracks wide enough to let more water in next spring. We’ve repointed chimneys in Rodgers Forge that looked fine from the ground but had mortar joints crumbling behind the flashing. We’ve rebuilt crowns in West Towson where a $400 repair three years earlier would have prevented a $3,800 rebuild. Our technicians carry professional-grade materials from DuraFlex, HeatShield, and Copperfield on every truck, and every repair starts with a Level-2 camera inspection so you see what we see. The 90-Day Done Right Promise covers every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar Repointing is the careful removal of deteriorated mortar between bricks and its replacement with new, properly matched mortar. In Towson, we see accelerated mortar decay in neighborhoods like Stoneleigh and Ruxton, where mature trees keep chimneys shaded and damp for months at a time. Our technicians grind out failed joints to proper depth, match the sand and cement profile to your existing mortar, and tool the finish so the repair disappears into the wall. We use HeatShield-compatible refractory mortars where heat exposure demands it, and we document the full joint profile with photos before and after.
Spalling Brick Repair
Spalling Brick Repair addresses what occurs when water trapped inside bricks freezes, expands, and pushes off the face of the brick, leaving a pitted, crumbling surface. Towson’s clay-heavy soil and older brick stock in neighborhoods like Anneslie and Wiltondale make this especially common in homes built before 1980. We remove spalled bricks to sound substrate, source matching replacement brick when possible, and rebuild with proper weep holes and drainage so the problem does not repeat. For widespread spalling, we’ll show you the camera footage and explain whether spot repair or partial rebuild makes more sense.
Chimney Waterproofing
Chimney waterproofing is the application of a vapor-permeable sealant that blocks liquid water from entering masonry while allowing trapped moisture to escape. Towson’s average annual precipitation of 42 inches, combined with wind-driven rain off the Chesapeake, means unprotected chimneys absorb significant water six months of the year. We apply professional-grade waterproofing agents from Copperfield and Famco, never the hardware-store acrylics that trap moisture and accelerate damage. A typical waterproofing treatment covers the full above-roof masonry, the crown, and the top course of flashing, and lasts 7-10 years with proper maintenance.
Flashing Repair
Flashing is the metalwork that bridges the gap between your chimney and roof, and it’s the single most common source of chimney-related leaks we find in Towson. The combination of older homes with stepped flashing and newer homes with substandard counter-flailing installation keeps us busy in neighborhoods from Hampton to Loch Raven Village. We repair or replace flashing using proper base and counter components, sealed with high-temperature sealants compatible with your roofing material. Every flashing repair includes a water test and photo documentation of the sealed joints.
Chimney Rebuilding
Chimney rebuilding becomes necessary when structural integrity is compromised by widespread mortar failure, major spalling, or leaning caused by foundation settlement. In Towson, we’ve rebuilt chimneys in historic homes near the courthouse that had been patched repeatedly by previous owners until partial rebuild was the only sound option. Our rebuilds use matching brick and proper structural reinforcement, with rebuilt crowns poured to proper slope and overhang. We stage materials carefully, protect landscaping, and complete most rebuilds in 3-5 days with the chimney fully operational at the end of each workday.
Tuckpointing
Tuckpointing is the decorative and functional technique of cutting narrow grooves in mortar joints and filling them with contrasting putty to create the appearance of fine, precise joints. Many Towson homes in the Historic District and surrounding areas have original tuckpointing that has weathered poorly due to incompatible Portland cement repairs from past decades. We remove improper repairs, restore the original joint profile, and match the color and texture so the facade reads as it was designed. This is specialized work; our technicians train for two years before leading a tuckpointing crew.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from industry-trusted manufacturers. DuraFlex stainless steel liners and components form the backbone of our relining and repair work when internal flue restoration is part of the scope. We’ve installed hundreds of DuraFlex systems in Towson homes and stock the full range of diameters and adaptors on our trucks, which means no waiting for parts on most jobs. HeatShield’s cerfractory resurfacing system allows us to restore deteriorated clay flue liners without full replacement in qualifying chimneys, and our technicians are certified in their application protocol. We’ve completed HeatShield restorations in homes from Lutherville to Parkville with results that hold up to annual inspection.
Copperfield supplies our waterproofing agents, crown repair compounds, and many of our specialty flashing components. Their vapor-permeable treatments are the only ones we apply, because we’ve seen what trapped moisture does to Towson brickwork. Famco caps and dampers round out our repair inventory, with stainless steel and copper options that outlast the galvanized products sold at retail. Whether your chimney was originally built with these brands or any other make, we can source compatible repair materials and complete the work to specification. Our home page lists our full service offerings if you’re unsure whether repair or replacement makes sense for your situation.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on exterior brick means water is moving through your masonry and depositing salts as it evaporates. In Towson, we see this most often on north-facing chimneys that never fully dry out between rains. It’s not just cosmetic; the same water movement is degrading your mortar from the inside.
- Chunks of brick or mortar in your yard or gutters indicate active spalling or joint failure. We found a homeowner in Mays Chapel who’d been sweeping up brick fragments for two seasons before calling, by which time the repair had tripled in scope. Loose masonry overhead is a genuine hazard.
- Rust stains on the chimney face or roof near the flue mean your cap or crown has failed and water is reaching the metal flue liner or damper assembly. Left unaddressed, this progresses to liner failure and potential carbon monoxide leakage into living spaces. A camera inspection will show the extent.
- Damp or stained drywall on interior walls adjacent to the chimney breast is nearly always failed flashing or crown leakage, not roof leakage as homeowners often assume. We’ve traced dozens of these in Towson rowhouses and detached homes alike; the repair is chimney-specific, not roofing.
- Visible leaning or separation from the house wall signals foundation settlement or structural failure requiring immediate assessment. This is not a wait-and-see situation. We’ve stabilized leaning chimneys in Carney and Perry Hall with proper underpinning and rebuild, but delay only increases risk and cost.

How Much Does Chimney Repair Cost in Towson?
Chimney repair costs in Towson vary with the scope of damage, access difficulty, and materials required. A typical mortar repointing job on a standard single-flue chimney runs $1,200-$2,400. Spalling brick repair for localized damage starts around $800 and ranges to $2,800 if multiple courses are involved. Chimney waterproofing for average above-roof height costs $450-$850. Flashing repair runs $650-$1,500 depending on roof pitch and whether step or counter-flashing is involved. Full or partial chimney rebuilding is the most significant investment, typically $3,500-$8,500 for partial rebuilds and $8,000-$15,000 for full teardown and reconstruction.
Several factors move these numbers. Chimney height above roofline affects scaffolding and labor time. Historic homes with delicate brick or ornate corbelling require slower, more careful work. Interior flue damage discovered during camera inspection may add liner repair or relining to the scope. Towson’s freeze-thaw severity means we occasionally find hidden water damage that wasn’t visible from the ground.
To avoid overpaying, get a camera inspection before committing to major work. We’ve provided free second opinions on written estimates from other companies and found that some recommended rebuilds were actually $1,200 repointing jobs. Our estimates are free, itemized, and come with photos you can see for yourself. We also offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans.

Frequently Asked Questions - Chimney Repair in Towson
Chimney repair fixes structural and functional damage to the chimney’s masonry, metal components, and waterproofing systems, while chimney cleaning removes combustible creosote deposits from the flue interior.

Most standard repairs like repointing, flashing repair, or waterproofing are completed in a single visit of 4-6 hours.
