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 Owings Mills Homeowners
A chimney liner rebuild in Owings Mills typically costs between $2,800 and $6,500 depending on whether you need a stainless steel liner replacement, a partial rebuild of damaged masonry, or a full chimney reconstruction. Most liner installations and partial rebuilds are completed in a single day, with full rebuilds taking two to three days. Hearthstone Chimney Co. has been serving Owings Mills and Baltimore County since 1984, and our Level-2 camera inspections show you exactly what needs fixing before any work begins. Call us at (443) 998-2617 for a free, no-obligation estimate with upfront pricing.
We’ve rebuilt chimneys in every corner of Owings Mills, from the mature neighborhoods near Soldiers Delight to the hillside homes off Painters Mill Road where freeze-thaw cycles crack mortar joints faster than in flatter parts of Baltimore County. Our technicians arrive in uniform, have passed background checks, and carry professional-grade materials from Gelco, Olympia Chimney, and Famco on every truck. The 90-Day Done Right Promise governs every job: if it’s not right, we make it right, in writing, with no arguing and no paperwork chase. That’s the Keystone Standard we’ve operated by for over 42 years.
Russell Haines built this company on a simple idea - homeowners deserve to see what they’re paying for and understand why it matters. In Owings Mills, where many homes were built during the 1970s and 1980s with clay tile liners now reaching end of life, we’ve documented hundreds of cases where a deteriorating liner posed real risks of carbon monoxide leakage or chimney fire. We don’t sell fear. We show you the photos, explain the mechanics in plain English, and let you decide. When you’re ready, a live person answers our phones 24 hours a day, 7 days a week.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner Installation
A stainless steel liner is a continuous metal flue pipe inserted inside your existing chimney structure, creating a sealed combustion path from appliance to cap. In Owings Mills, we install stainless steel liners most often when clay tile liners have cracked from thermal shock or when homeowners convert to a high-efficiency gas insert that requires a smaller, properly sized flue. Our crews use DuraFlex and Olympia Chimney stainless steel components, measured and cut on-site for a precise fit that meets NFPA 211 standards. Every stainless installation includes a new connector, insulation wrap where required by code, and a lifetime warranty on the liner itself.
Flexible Liner Installation
Flexible liners are corrugated stainless steel tubes that navigate offsets, bends, and tight clearances where rigid pipe cannot pass. We use flexible liners in Owings Mills for historic homes with angled chimney throats, for fireplace inserts in pre-fabricated metal chimneys, and in any situation where the flue path isn’t perfectly straight. Our technicians carry multiple diameters and lengths of DuraFlex flexible liner on every truck, which means most flexible liner jobs in neighborhoods like Mays Chapel and Garrison are completed without a second trip. The corrugated design allows us to thread the liner past chimney shoulders that would otherwise require costly masonry demolition.
Liner Replacement
Liner replacement becomes necessary when your existing liner, whether clay tile, metal, or poured refractory, has deteriorated beyond repair. In Owings Mills, we see this most in homes built between 1965 and 1990 where original clay tile liners have spalled, shifted, or separated at the joints after decades of heating and cooling cycles. Our replacement process begins with a full Level-2 inspection including video documentation of every foot of flue, so you see exactly why replacement is recommended rather than repair. We remove the damaged liner, clean the flue walls, and install a new stainless or flexible system sized precisely for your appliance type and BTU output.
Partial Chimney Rebuild
A partial rebuild addresses structural failure limited to the chimney crown, top courses of brick, or the exterior wythe while the interior flue and lower structure remain sound. In Owings Mills, partial rebuilds are common after ice damming damages crown mortar, or where the top six to eight courses have loosened from years of water infiltration at the cap line. We dismantle only the compromised section, salvage usable brick when possible, and rebuild with matching masonry units and Type N or Type S mortar appropriate to Baltimore County’s freeze-thaw climate. Every partial rebuild includes a new poured concrete crown with proper overhang and drip edge, plus a stainless steel cap from Famco or Copperfield to protect the investment.
Full Chimney Rebuild
A full chimney rebuild is required when structural integrity has failed throughout the stack, typically from long-term water damage, foundation settling, or catastrophic flue fire that has cracked the exterior shell. We’ve completed full rebuilds in Owings Mills for homeowners in Woodholme and Deer Park where chimneys had essentially become masonry shells held together by habit rather than mortar. Our rebuild process includes temporary bracing of the roof opening, careful demolition to protect siding and roofing, foundation inspection, and reconstruction with matching brick and proper flue sizing for your heating appliance. A full rebuild takes two to three days and includes all new components: flue liner, crown, cap, flashing, and a written 90-Day Done Right Promise.
Liner Repair
Liner repair is appropriate for localized damage - a few cracked tiles in the upper flue, minor joint separation, or small gaps in a poured refractory liner - where full replacement would be unnecessary expense. In Owings Mills, we often repair upper flue sections that have taken the brunt of acid condensation from modern, efficient appliances. Our repair methods include HeatShield cerfractory resurfacing for poured liners, tile replacement with matching refractory units, and joint repair with high-temperature refractory sealants. We never recommend repair over replacement without camera evidence you can see for yourself, and we’ll tell you plainly when a repair is a temporary fix that will need addressing in a few years.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Gelco liner systems across Baltimore County, and we stock their stainless steel components, termination caps, and connector kits on every truck. Gelco’s smooth-wall stainless liners handle the condensing flue gases from high-efficiency appliances particularly well, which matters in Owings Mills where many homeowners have upgraded to efficient gas systems in older homes. When we specify Gelco, it’s because their engineering matches the application - not because it’s the only brand we know.
Olympia Chimney has been our go-to for flexible liner applications and for their proprietary insulation systems that maintain proper flue temperatures in exterior chimneys. We’ve run Olympia Chimney liners in hillside homes from Reisterstown to Pikesville where chimneys on the north face never fully warm up, and their products perform consistently in those demanding conditions. Famco caps and Copperfield flashing components round out our inventory - Famco for their stainless and copper cap designs that shed water properly on Maryland’s wind-driven rains, Copperfield for their counter-flashing and step-flashing details that we’ve adapted to the varied roof pitches common in Owings Mills subdivisions. Whether your existing system is from one of these manufacturers or any other make, we can inspect it, source compatible components, and restore it to proper function.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick indicates water is moving through the masonry, dissolving salts, and depositing them on the surface. In Owings Mills, where clay soils hold moisture against foundations and chimney bases, efflorescence often signals that the liner has failed and combustion gases are condensing inside the flue, accelerating mortar decay. Left unaddressed, this moisture cycle destroys brick from the inside out.
- Bits of clay tile in your firebox or at the cleanout door mean your original liner is spalling, cracking, or collapsing. These fragments are pieces of the flue that have detached from thermal stress or acid corrosion. A compromised clay liner cannot contain chimney fires or prevent carbon monoxide from leaking into wall cavities, and the debris itself can block proper draft.
- Smoke or odors entering your living space during operation suggests liner failure, improper sizing, or blockage that is reversing the pressure gradient in your flue. In tightly constructed Owings Mills homes from the 1980s and 1990s, negative pressure from exhaust fans can compound draft problems caused by a deteriorating liner. This isn’t just an inconvenience - it’s a sign that combustion products aren’t exiting as designed.
- Visible cracks in the chimney crown or missing mortar joints allow water directly into the chimney structure, where freeze-thaw cycles in Baltimore County winters expand cracks exponentially. A damaged crown is often the entry point that destroys the liner below; we inspect the crown, flue, and interior as a system because they fail together. Crown cracks visible from the ground mean it’s time for a Level-2 inspection.
- Rust staining on the chimney face or metal components indicates persistent moisture inside the flue, usually from a liner that is no longer venting gases hot enough to prevent condensation. Gas appliances are particularly hard on liners when the flue is oversized for the reduced BTU output, and we’ve seen this pattern repeatedly in Owings Mills homes where original fireplaces were converted to gas inserts without proper relining.

How Much Does Chimney Liner & Rebuild Cost in Owings Mills?
A typical stainless steel liner installation in Owings Mills runs $2,800 to $4,200 for a straightforward single-flue chimney with standard height and roof access, which affects how much Chimney Liner & Rebuild costs overall. Flexible liner installations for fireplace inserts or offset flues generally fall between $2,200 and $3,800 depending on length and diameter. Liner replacement where we must remove damaged clay tile before installing the new system adds $400 to $800 for the extraction labor. Partial rebuilds of the upper chimney, including new crown and cap, range from $3,500 to $6,500 based on how many courses need replacement and whether matching brick must be sourced. Full chimney rebuilds in Owings Mills typically start at $8,000 and can reach $15,000 or more for tall stacks on multi-story homes with complex rooflines.
Several factors move these prices within the ranges. Height matters: a chimney on a three-story Colonial in Mays Chapel requires more scaffolding and labor than a rancher in Randallstown. Accessibility affects cost too - chimneys tight against the roofline or surrounded by mature trees take longer to work around. The appliance type determines liner specification: wood-burning requires a heavier gauge than gas, and oil flues have their own corrosion considerations. Finally, the condition of the existing structure dictates whether we can work with what’s there or must rebuild portions to provide a sound substrate.
To avoid overpaying, get a second opinion on any estimate over $2,500 - we offer free second opinions on any written estimate from another company, no strings attached. Be wary of any sweep who recommends work without camera evidence you can see, or who cannot explain why a particular liner diameter or material is specified. Our estimates include all materials, labor, permits if required by Baltimore County, and disposal. We also offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans.

Frequently Asked Questions - Chimney Liner & Rebuild in Owings Mills
A chimney liner rebuild is the process of restoring or replacing the internal flue system and any damaged exterior masonry that contains and protects it. The liner is the critical barrier that channels combustion gases safely from your fireplace, stove, or furnace to the outdoors while protecting the surrounding structure from heat and corrosion. At Hearthstone Chimney Co., we use the term to encompass everything from stainless steel liner insertion to partial or full masonry reconstruction, depending on what your chimney needs.
Most stainless steel and flexible liner installations are completed in a single day, with our technicians arriving in the morning and finishing by late afternoon. Partial rebuilds typically require one to two days depending on how many courses of brick need replacement and whether matching materials must be sourced. Full chimney rebuilds take two to three days, with weather-dependent steps like mortar curing factored into the schedule. We’ll give you a specific timeline with your written estimate.
Stainless steel liner installations typically run $2,800 to $4,200, flexible liners $2,200 to $3,800, partial rebuilds $3,500 to $6,500, and full rebuilds from $8,000 upward depending on height and complexity. These ranges reflect actual jobs we’ve completed in Owings Mills neighborhoods from Deer Park to Woodholme. Your exact price depends on flue dimensions, roof access, appliance type, and structural condition - all documented during our free Level-2 inspection.

Clear a path to your fireplace or appliance area and remove any fragile items from the mantel and hearth, as our equipment and materials require working space. For exterior work, trim back any branches within three feet of the chimney and ensure we have driveway or street access for our truck and ladder setup. Our technicians bring protective coverings for floors and furniture, and we clean thoroughly after completion. If you have previous inspection reports or repair estimates, have them available - they help us understand your chimney’s history.
