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.

AfterTrusted Chimney Liner & Rebuild for Baltimore Homeowners
A chimney liner and rebuild in Baltimore typically costs between $2,800 and $7,500 depending on whether you need a stainless steel liner replacement or a full masonry rebuild, and most projects are completed in one to two days. Hearthstone Chimney Co. has been serving Baltimore homeowners since 1984, and our Level-2 camera inspections show you exactly what needs fixing before any work begins. Call us at (410) 849-6273 for a free estimate with no obligation.
We’ve rebuilt chimneys in Federal Hill rowhomes with crumbling century-old flues, installed flexible liners in tight Canton brickwork, and replaced rusted-out liners in Parkville split-levels where the original builder never expected the fireplace to see forty years of use, and we also offer our Chimney Liner & Rebuild in Baltimore throughout the metro area. Baltimore’s freeze-thaw cycles, our heavy clay soils, and the age of our housing stock mean liner failure and masonry deterioration aren’t rare here. They’re predictable. Russell Haines and our team have seen it all twice, and we document every inspection with photos you can see and a plain-English verdict you can understand. No surprises on the bill. No arguing if something’s not right. That’s the 90-Day Done Right Promise, backed in writing.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a rigid or corrugated metal tube we install inside your existing flue to contain combustion gases and protect your masonry from corrosive byproducts. In Baltimore, we recommend these for wood-burning and gas fireplaces alike because they handle our temperature swings and resist the moisture damage we see after wet winters. We source our stainless liners from Olympia Chimney and Famco, sizing each one to your appliance’s BTU output and your chimney’s interior dimensions, not guesswork.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that navigate offset flues, chimney bends, and tight clearances where a rigid pipe won’t fit. We install a lot of these in Baltimore’s older neighborhoods, particularly in Fells Point and Hampden, where original construction left irregular chimney throats and no straight shot from fireplace to crown. Our technicians measure with video inspection first, then pull the correct diameter from our stocked inventory, most often completing the installation in a single visit.
Liner Replacement
Liner replacement becomes necessary when your existing clay tile liner is cracked, spalled, or missing sections, or when a previous metal liner has corroded through. In Baltimore Highlands and Brooklyn Park, we regularly find clay liners that have deteriorated from decades of condensation cycling, especially in chimneys venting high-efficiency appliances. We remove the failed liner, inspect the surrounding masonry with our camera system, and install a new HeatShield or stainless system sized to current NFPA 211 standards.
Partial Rebuild
A partial rebuild addresses damaged sections of your chimney without tearing down what remains sound. We see this need most often above the roofline, where Baltimore’s driving rains and freeze-thaw cycles destroy crowns, wash out mortar joints, and loosen brick courses. Our masons match existing brick and mortar color where possible, rebuild the crown with proper slope and overhang, and flash the chimney to shed water correctly. The result should look like it was always there.
Full Chimney Rebuild
A full rebuild is required when structural integrity is compromised throughout the chimney stack, from firebox to crown. We’ve completed Rosedale Chimney Liner & Rebuild projects and full rebuilds in Overlea on homes where original construction used salvaged brick, where foundation settling created a lean, or where long-neglected water intrusion rotted the structure from within. We dismantle carefully, salvage what we can, pour a new footing if needed, and rebuild to current code with proper liners, caps, and ventilation. Most full rebuilds take three to five days.
Liner Repair
Liner repair with HeatShield cerfractory flue sealant restores cracked clay tile liners without full replacement when damage is limited and the tile structure remains sound. We see good candidates for this in Catonsville and Chimney Liner & Rebuild - Catonsville projects, as well as Pikesville, where liners have minor cracking from a single overfire event or thermal shock but haven’t deteriorated throughout. The process involves cleaning, video inspection, application of the HeatShield compound, and a final camera verification that the seal is continuous and smoke-tight.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Olympia Chimney stainless steel liner systems across Baltimore County and the city. Their multi-flue and single-flue products handle our regional heating demands reliably, and we stock common diameters and components so we’re not ordering parts while your fireplace sits out of commission. When an Olympia system needs attention, we know the product line well enough to diagnose without experimentation.
Famco caps, dampers, and termination fittings are standard on many of our liner installations, particularly where we need custom solutions for odd-sized flues or specific venting configurations. We’ve worked with their product range long enough to know when a standard cap will suffice and when a custom-fabricated solution is the right call. Same with HeatShield, whose cerfractory repair system we’ve used to restore liners that other companies would have unnecessarily replaced. Whether you have one of these brands or any other make, we can help. Our technicians carry the tools and training to work with what you’ve got, not force a one-size-fits-all approach.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means moisture is moving through your masonry, dissolving salts, and depositing them on the surface. In Baltimore, this accelerates after wet winters and indicates your liner may be leaking combustion gases into the brick, or your crown and flashing are failing. Either way, the freeze-thaw damage compounds every season you wait.
- Flakes or pieces of clay tile in your firebox are pieces of your liner that have spalled off from thermal stress or moisture damage. Once the liner loses structural integrity, hot gases can reach combustible framing through gaps in the masonry. This is not a cosmetic issue. We need to inspect with a camera to determine whether repair or replacement is appropriate.
- Rust stains on your chimney breast or ceiling mean water is entering through a failed crown, deteriorated flashing, or a rusted metal liner. In rowhomes with shared walls, this can damage your neighbor’s property too. We trace the source with video inspection and moisture testing, then fix what actually needs fixing rather than applying a bandage.
- Smoke backing up into your room suggests a blocked flue, improper liner sizing, or a liner that has collapsed or disconnected. This is a genuine safety concern, carbon monoxide exposure among the risks. Don’t use the fireplace until we’ve determined the cause and corrected it.
- A leaning chimney or visible mortar gaps indicate structural failure, often from foundation movement, long-term water damage, or original construction that didn’t account for Baltimore’s expansive clay soils. A leaning chimney above the roofline can collapse in high winds. We assess whether stabilization, partial rebuild, or full rebuild is the right and safe approach.

How Much Does Chimney Liner & Rebuild Cost in Baltimore?
A typical stainless steel liner installation in Baltimore runs $2,800 to $4,500 depending on flue diameter, chimney height, and whether we need to navigate offsets or multiple appliance connections. Flexible liner installations in tight spaces generally fall in the same range, sometimes slightly higher if custom termination fittings are required. HeatShield liner repairs typically cost $1,200 to $2,400 for a standard fireplace flue, making them a practical option when damage is limited and the tile structure is sound.
Partial rebuilds above the roofline in Baltimore generally range from $3,500 to $6,000, depending on how many courses need replacement, whether the crown needs reconstruction, and the condition of your flashing. Full chimney rebuilds start around $7,500 and can exceed $12,000 for tall structures with complex footing requirements or historic preservation constraints in neighborhoods like Roland Park or Mount Washington.
Several factors move these numbers. Accessibility matters: a chimney on a steep roof in Pikesville takes longer to scaffold safely than one on a flat roof in Canton. The number of flues and appliances connected affects liner sizing and material costs. Hidden damage uncovered during demolition, such as deteriorated smoke chambers or compromised fireboxes, may need correction before the main work proceeds. We price for what we can see and what experience tells us to expect, then communicate any necessary adjustments immediately, with photo evidence, before proceeding.
To avoid overpaying, get a second opinion on any written estimate over $2,500. We offer free second opinions for exactly this reason. Also beware of low bids that omit liner sizing verification, proper permit pulling, or cleanup. A liner that doesn’t fit your appliance’s output is worse than no liner at all. Our free estimates include the camera inspection, photo documentation, and a written scope of work with one total price.
