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 Ellicott City Homeowners
A Chimney Liner & Rebuild in Ellicott City typically costs between $1,800 for a straightforward stainless steel liner replacement and $8,500 or more for a full chimney rebuild involving multiple flues and masonry restoration. Most liner replacements are completed in a single day, while partial and full rebuilds usually take two to five days depending on weather and the extent of masonry work needed. If you’re seeing crumbling mortar, water stains on interior walls near the chimney chase, or your fireplace is drafting poorly even with the damper open, the flue liner or chimney structure itself is likely compromised.
We’ve been doing this work in Ellicott City and Howard County since 1984. That’s over 42 years of crawling into flues in homes from Old Ellicott City up the hill to Dunloggin and out toward Centennial Park. Russell Haines built this company on the idea that a chimney sweep should explain what he found the way he’d want it explained to his own mother: straight, with photos you can see, and a plain-English verdict on what needs doing now, what can wait, and what doesn’t need doing at all. We back every liner and rebuild job with our 90-Day Done Right Promise in writing - if it’s not right, we come back, no paperwork, no arguing. Calls are answered by a live person 24 hours a day, 7 days a week at (410) 305-7884.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a rigid or corrugated metal tube inserted inside your existing flue to create a sealed, properly sized passage for smoke and combustion gases. In Ellicott City, we install these most often in homes built between 1960 and 1990 where the original clay tile liner has cracked from thermal cycling or where a new high-efficiency insert has been installed that the original flue cannot safely handle. Our technicians measure the flue precisely and fabricate the liner from DuraFlex or Olympia Chimney stock on-site, then secure it with proper top connections and insulation meeting NFPA 211 standards. Most stainless steel liner installations are completed in one day, with the firebox restored and the system ready for use by evening.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offsets and bends in chimney flues where a rigid liner cannot pass. We use these frequently in Ellicott City’s older homes, particularly in the historic district near Main Street where chimneys were often built with sharp offsets to accommodate structural constraints. The flexibility allows us to thread the liner through without dismantling interior walls or exterior masonry, preserving original plaster and trim that would be costly to restore. Our crews have installed flexible DuraFlex liners in flues with up to 30-degree offsets, and we always video-scan the completed installation to verify full circumferential contact with the flue walls.
Liner Replacement
Liner replacement becomes necessary when the existing liner, whether clay tile, aluminum, or an older stainless unit, has deteriorated beyond repair. In Ellicott City, we see this most often after chimney fires that have cracked tile, or in homes where an unlined brick chimney has been used for years and the mortar joints have eroded, exposing the brick to corrosive flue gases. We remove the damaged liner when accessible, or in some cases abandon it in place and install a new liner of appropriate diameter and material. Every replacement includes a Level-2 camera inspection of the completed work, with photos provided to you showing the new liner’s condition from top to bottom.
Partial Rebuild
A partial rebuild addresses specific sections of the chimney that have failed while the majority of the structure remains sound. Common scenarios in Ellicott City include rebuilding the top four to six courses of brick that have spalled from freeze-thaw damage, reconstructing a deteriorated smoke chamber, or replacing a damaged chimney crown that has allowed water to infiltrate and weaken the masonry below. We match existing brick and mortar where possible, using compatible materials that will weather at the same rate as the original construction. Most partial rebuilds are completed in two to three days, with scaffolding kept to a minimum to protect your landscaping and roof.
Full Chimney Rebuild
A full chimney rebuild is required when the structural integrity of the entire stack has been compromised, typically from long-term water infiltration, foundation settling, or catastrophic damage from a chimney fire or lightning strike. In Ellicott City, we’ve done full rebuilds on century-old homes in the historic district and on 1970s colonials where the chimney was built with salvaged brick that simply reached the end of its service life. We dismantle the chimney to sound masonry or the roofline, salvage what brick we can for matching purposes, and rebuild to current code with proper flue sizing, liner installation, and crown construction. A full rebuild typically takes four to five days and includes a complete Level-2 inspection and documentation package.
Liner Repair
Liner repair is appropriate when the damage to an existing liner is localized and the overall system remains structurally sound. We use HeatShield cerfractory sealant for resurfacing cracked or pitted clay tile flues, and Gelco’s stainless repair sleeves for isolated breaches in metal liners. In Ellicott City, we’ve successfully repaired liners with minor cracking from thermal shock, saving homeowners the cost of full replacement when the damage hasn’t compromised the flue’s ability to contain combustion products. Every repair is followed by a video inspection to verify the seal, and we warranty liner repairs under the same 90-Day Done Right Promise that covers all our work.

Brands We Service for Chimney Liner & Rebuild
We’ve worked with DuraFlex flexible and rigid stainless liners since their introduction to the U.S. market, and we stock their full range of diameters and connection components. Their corrugated flexible products have proven particularly reliable in Ellicott City’s offset flues, and we’ve installed hundreds of their systems with zero material failures to date. When we specify DuraFlex, it’s because we’ve seen how their .006-inch and .012-inch wall thickness options hold up in real-world conditions over decades of service.
HeatShield’s cerfractory resurfacing system is our go-to for clay tile liner repair, and we’ve completed more HeatShield applications in Howard County than any other company in our service area. Their proprietary blend of ceramic and refractory materials bonds to existing tile at temperatures exceeding 2,900 degrees, creating a smooth, sealed surface that restores the flue’s integrity without full replacement. We also regularly install Gelco stainless steel liners and components, particularly their premium 316Ti alloy products for oil and wood-burning applications where corrosion resistance is critical. Whether you have a DuraFlex, HeatShield, Gelco, or any other make of liner or chimney component, we can inspect it, repair it, or replace it with the right material for your system and fuel type.
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 Ellicott City, this often appears after our wet springs and freeze-thaw winters, and it means the mortar joints or crown have failed, allowing moisture to reach the liner and accelerate deterioration.
- Bits of clay tile in the firebox or falling into the cleanout mean the flue liner is spalling or separating, creating gaps where creosote can accumulate and heat can reach combustible framing. This is not a maintenance item for next season; it’s a fire hazard that requires immediate evaluation and likely liner replacement.
- Smoke backing up into the room even with the damper fully open suggests the flue is obstructed, improperly sized, or the liner has collapsed inward. We’ve traced this symptom in Ellicott City homes to everything from a detached flexible liner that created a damper effect to a partially collapsed clay tile that reduced flue area below code minimums.
- A strong, persistent odor of creosote during humid weather means moisture is entering the chimney and activating deposits on the liner surface. The smell is unpleasant, but the underlying condition - water infiltration through cracked crown, missing cap, or failed mortar - is what will destroy the liner and surrounding masonry if not addressed.
- Visible cracks in the chimney crown or missing chunks of mortar between bricks expose the entire structure to accelerated weathering. In Ellicott City’s climate with its freeze-thaw cycles and occasional ice storms, water enters these openings, expands when it freezes, and progressively destroys the chimney from the outside in. Crown repair or rebuild stops this process before it reaches the liner.

How Much Does Chimney Liner & Rebuild Cost in Ellicott City?
Learn how much Chimney Liner & Rebuild costs: a typical stainless steel liner replacement in Ellicott City runs $1,800-$3,400 for a standard wood-burning fireplace with straight flue and accessible cleanout. Flexible liner installations in offset flues or for multi-appliance connections typically fall between $2,400-$4,200. Liner repair using HeatShield cerfractory sealant ranges from $800-$1,800 depending on the linear footage and severity of damage. Partial rebuilds - crown replacement, top course rebuild, or smoke chamber parging - generally cost $1,200-$4,500. Full chimney rebuilds in Ellicott City, including demolition, new masonry, liner installation, and cap, typically range from $5,500-$8,500 and can exceed that for multi-flue structures or historic preservation requirements.
| Service | Typical Range in Ellicott City | Most Common Factors |
|---|---|---|
| Stainless Steel Liner (straight flue) | $1,800 - $3,400 | Flue diameter, appliance type, insulation requirements |
| Flexible Liner (offset flue) | $2,400 - $4,200 | Offset angle, total length, connection complexity |
| HeatShield Liner Repair | $800 - $1,800 | Linear footage, crack severity, access |
| Partial Rebuild | $1,200 - $4,500 | Height of rebuild, brick matching, scaffolding needs |
| Full Chimney Rebuild | $5,500 - $8,500+ | Flue count, height, historic requirements, foundation |
Several factors push these numbers up or down. The height of your chimney matters - a two-story colonial in Dunloggin with a steep roof pitch requires more labor and scaffolding than a rancher in Dorsey’s Search. Accessibility for our equipment affects timing and cost; tight lots in Old Ellicott City sometimes need hand-carrying materials. The type of appliance served determines liner specification - wood stoves and oil furnaces need higher-grade alloys than gas logs. And the condition of the existing structure matters: a liner replacement in sound masonry is straightforward, but the same liner in a chimney with a failed crown and saturated brick may require partial rebuild before the liner can be safely installed.
To avoid overpaying, get a second opinion on any estimate over $2,000 - we provide these free, with no obligation, and we’ll show you exactly what we found with our camera so you can compare apples to apples. Be wary of any contractor who recommends a full rebuild without video documentation you can see for yourself, or who cannot explain why a liner replacement won’t suffice. Our estimates include all materials, labor, permits if required by Howard County, and debris removal. Nothing is added after you approve the number.

Frequently Asked Questions - Chimney Liner & Rebuild in Ellicott City
A chimney liner is a protective barrier inside your flue that channels combustion gases safely out of your home while protecting the surrounding masonry from heat and corrosion. It needs replacement or rebuild when cracks, gaps, or deterioration allow heat, moisture, or gases to reach combustible materials or when the liner is improperly sized for your appliance, causing poor draft and dangerous creosote buildup. In Ellicott City, we most commonly replace liners in homes built before 1980 where original clay tile has failed, or where a heating system conversion has rendered the existing flue incompatible.
A standard stainless steel or flexible liner replacement is typically completed in a single day, with the system ready for use by evening. Partial rebuilds requiring masonry work generally take two to three days, and full chimney rebuilds from the roofline up require four to five days depending on weather and the complexity of matching existing materials. We schedule rebuilds with weather contingencies built in, and we never leave your home unprotected - temporary caps and weatherproofing are standard on multi-day jobs.
We also offer Chimney Liner & Rebuild - Jessup. Chimney liner replacement in Ellicott City typically costs between $1,800 and $4,200 depending on liner type, flue configuration, and appliance requirements. Partial rebuilds range from $1,200 to $4,500, while full rebuilds generally start at $5,500 and can exceed $8,500 for complex multi-flue structures.

We register all manufacturer warranties on your behalf and provide documentation so you’re covered at every level.
Clear a path to your fireplace or appliance and remove any fragile items from the mantel and hearth area, as our equipment and materials require space to maneuver.
