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 Rockville Homeowners
If you’re wondering how much Chimney Liner & Rebuild costs, Rockville, MD work typically runs between $2,800 and $12,000 depending on whether you need a liner replacement alone or a full masonry rebuild from the roofline up. Most liner-only jobs we complete in Rockville run $2,800-$5,200 when no masonry repair is required, and we’ll have that number on the page in writing before anything starts. A cracked flue liner isn’t a small repair, and it’s not one you can safely put off through a Maryland winter. Since 2009, our crews have handled more than 38,000 inspections and cleanings across Montgomery County, with a documented photo record on every single job under Clause 4 of the Haven Standard. If your liner is failing, call (571) 376-7052 for a free camera inspection and a written price you can hold us to.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel flue liner is the permanent fix for a cracked clay tile liner, and it’s what we recommend for most Rockville homes built before the 1980s. The old terra cotta tiles inside those chimneys weren’t built for modern gas appliances, and we routinely see them cracked, shifted, or missing entirely once the camera goes down. We size the liner to your exact flue dimensions rather than shoving in the closest stock size, because an oversized liner drafts poorly and an undersized one creates a fire hazard. Materials come from trusted manufacturers like Olympia Chimney, and you get the spec sheet and model number in writing before installation.
Flexible Liner
A flexible stainless liner is the right call when your existing chimney has offsets or bends that a rigid liner can’t navigate without tearing out masonry. We use DuraFlex liners for these jobs, running them down through the throat and around the smoke shelf where the flue shifts. The advantage of flexible liner is that it preserves your original masonry rather than requiring a tear-down to access the flue path. We camera the entire run after installation to confirm there are no kinks, snags, or gaps at the connections.
Liner Replacement
Liner replacement means pulling out the old clay tile or damaged metal liner and installing a new one, usually in a single day. In Rockville we see this most often in split-levels and colonials built between 1960 and 1985, where the original clay liner has spalled (the surface flaking away in thin layers) from decades of freeze-thaw cycles. We don’t recommend replacement until the camera footage shows us the damage, and we’ll show you those photos while we explain what they mean. When the old liner is removed, we clean the smoke chamber and flue walls before the new liner goes in, because a liner installed over a dirty flue is a liner that fails early.
Partial Rebuild
A partial rebuild restores the chimney from the roofline up when the upper section is spalling, leaning, or letting water into the home. This is one of the most common repairs we do in Chimney Liner & Rebuild in Bethesda and Rockville, where older brick chimneys take direct weather exposure on the north and west sides of homes. We rebuild the damaged courses with new brick and mortar to match the existing structure as closely as brick supply allows, then install or replace the chimney cap and crown. Every partial rebuild includes a camera inspection of the undamaged lower section to confirm the flue below is still sound, because rebuilding brick on top of a failing liner wastes your money.
Full Chimney Rebuild
A full rebuild is when the entire chimney, from the firebox to the crown, is demolished and rebuilt because the structural integrity is gone. This is a major job, and we don’t recommend it lightly. In Rockville, the most common drivers are long-term water intrusion that has rotted the mortar joints from the inside, or a chimney that’s visibly leaning away from the house. We handle the full scope: proper footings, new flue liner, smoke chamber parging, crown, cap, and flashing. Corrine Halstead, who leads our Rockville operation, personally reviews the camera footage on every full rebuild quote before a price goes to the customer.
Liner Repair
Liner repair is the middle ground when the liner has a localized problem, like a single cracked tile or a deteriorated joint, but the rest of the flue is sound. We use HeatShield’s joint repair system for these jobs, which applies a ceramic coating directly to the damaged section rather than replacing the entire liner. This works well for small repairs and carries a manufacturer’s warranty. We’ll tell you plainly when repair will hold and when it won’t, because patching a liner that’s failing in multiple places just means you pay twice.

Brands We Service for Chimney Liner & Rebuild
We work with materials from HeatShield, Gelco, Olympia Chimney, and Famco, and we stock OEM components for all of them because our buying network through Haven keeps prices where they should be. That means when we install a HeatShield joint repair, it’s genuine HeatShield ceramic sealant applied to their spec, not a generic refractory mortar out of a bucket. Our techs are trained on each system’s installation requirements, and every job is done to the manufacturer’s written instructions, which we include in your documentation packet.
Whether you have a Gelco cast-in-place liner, an Olympia stainless system, or we’re matching a Famco cap to an existing rebuild, we can handle the work and have the parts on hand or sourced within days. If your chimney has a liner we haven’t mentioned here, we’ll inspect it and give you a straight answer about what can and can’t be done. You won’t get an upsell disguised as brand loyalty.
BeforeAfterSigns You Need Chimney Liner & Rebuild Right Now
- Flakes of tile in the firebox. If you’re finding thin, curved pieces of terra cotta in the fireplace, your clay liner is spalling. That means the inner wall of your flue is actively crumbling, and each flake is a patch of exposed brick where heat and gases can reach the structure of your home.
- White staining on the exterior brick. Efflorescence, that chalky white deposit on the outside of the chimney, is water working its way through the masonry. When moisture gets into the flue and freeze-thaw cycles hit Rockville each January, it accelerates liner cracking from the inside.
- Smoke backing up into the room. If your fireplace smokes back into the house even with the damper fully open, the flue is either obstructed or the liner has narrowed or collapsed. Either way, carbon monoxide and smoke are being pushed into your living space instead of up and out.
- A smell of soot or creosote in rooms far from the fireplace. Odors travel when the flue isn’t sealed. A cracked liner lets combustion gases and odor into wall cavities, where they spread through the house. This is a health and fire issue, not just a stale smell.
- Visible cracking or shifting above the roofline. If the chimney above the roof is leaning, has step cracks in the mortar joints, or you can see brick faces popping off, the structure is compromised. A rebuild above the roof is the fix, and every season of delay adds cost.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Camera inspection, on us. We start with an NFPA 211 Level 2 inspection: a camera goes down the flue and records the actual condition of the liner, smoke chamber, and firebox. You see the footage in real time on a tablet, and we explain what’s on the screen in plain English. No charge for the inspection, no obligation.
- 2
Written scope and written price. Before any work begins, you get a written scope of work, a written price, and a written warranty. That’s Haven Standard Clause 1: everything in writing before anyone starts. We don’t do verbal estimates, and we never start a job with an open-ended price.
- 3
Protection and prep. Our crew lays drop cloths from the entry to the fireplace, covers furniture within 15 feet of the work area, and seals the firebox opening with plastic during demolition. We protect what you own before we touch what you hired us to fix.
- 4
The work, done to code. We install the liner or rebuild the masonry to NFPA 211 and Montgomery County code. Every connection is checked, every joint is sealed, and if we find something unexpected during the job, we stop and show you photos before we do anything beyond the agreed scope.
- 5
Documented proof it’s done right. After the work is complete, we run the camera again and give you a full photo record of the finished liner or rebuild. Like every job we’ve done since 2009, that record is yours to keep. If anything isn’t right, the 365-Day Done Right Promise means we come back and make it right.
How Much Does Chimney Liner & Rebuild Cost in Rockville?
A stainless steel liner replacement in Rockville typically runs $2,800-$5,200 depending on flue height, liner diameter, and whether we’re removing an existing clay tile liner or relining over it. A cast-in-place or HeatShield repair is usually $1,500-$3,200 when the damage is localized. A partial rebuild from the roofline up lands between $4,500 and $9,800 depending on how many courses of brick come down and what the new crown and cap cost. A full rebuild is $10,000-$20,000 or more if we’re rebuilding from the firebox up or reinforcing a foundation issue. For our Chimney Liner & Rebuild in Gaithersburg neighbors, these are real numbers for this market, not ranges copied from a national pricing chart. Here’s what moves the price:
- Flue height. A two-story colonial in Rockville needs 30-35 feet of liner; a rancher in Twinbrook needs 15-20. Liner is priced per foot, so house height matters more than square footage.
- Masonry condition. If the brick above the roofline is spalling, any liner job turns into a partial rebuild. We’ll show you the camera footage so you know why the number changed.
- Access. A steep roof pitch, a chimney in the center of a slate roof, or a flue that’s tight to neighboring walls adds labor. We price for what we’ll actually encounter, not a best-case scenario.
To avoid overpaying, get your price in writing and ask what’s included in the number. A liner quote that doesn’t mention smoke chamber parging, a new rain cap, or a crown seal is a quote that grows after the job starts. Our free estimate includes camera inspection, written scope, written price, and a written warranty. If you already have a written estimate from another company, bring it. We offer a free second opinion on any written estimate, and the comparison will show you exactly where the money goes. Call (571) 376-7052 and we’ll schedule the inspection.

Frequently Asked Questions - Chimney Liner & Rebuild in Rockville
Chimney liner and rebuild work covers everything inside and outside the flue: replacing a failed liner, repairing a damaged section, or rebuilding brick and masonry from the roofline up or the firebox out. The liner is the barrier between combustion heat and your home’s structure, and the rebuild restores the chimney’s structural integrity. In Rockville, most liner jobs involve replacing cracked clay tile with stainless steel, and most rebuilds involve the upper courses of brick above the roof where weather hits hardest. We inspect first, then recommend the least work that actually fixes the problem, and we give you the written scope before you commit.
A standard stainless liner replacement in Rockville takes one day, including removal of the old liner, installation, and the post-installation camera check. A partial rebuild above the roofline takes 2-3 days, including time for mortar to cure before we install the crown and cap. A full rebuild can take a week or more depending on height and weather, and we’ll give you a day-by-day schedule before work begins. Call (571) 376-7052 for an exact timeline on your chimney.
A liner replacement in Rockville runs $2,800-$5,200, a partial rebuild runs $4,500-$9,800, and a full rebuild starts around $10,000. The final number depends on flue height, liner type, masonry condition, and access. Every quote we give is a written fixed price, not an opening bid, and the free estimate includes a camera inspection so you know what’s driving the number. Call (571) 376-7052 and we’ll give you a price you can actually plan around, usually within 48 hours of the inspection.
Yes. We install and repair HeatShield joint repair systems, Gelco cast-in-place liners, Olympia Chimney stainless liners, and Famco caps and components. We stock OEM parts for all four and train our techs on manufacturer installation specs rather than improvising around them. If your existing system is from another manufacturer, we’ll inspect it and tell you honestly whether we can repair it or whether a replacement makes more sense. Bring us your brand and your questions, and we’ll give you a straight answer.
We answer the phone 24 hours a day, seven days a week, so if you’ve had a chimney fire or you suspect your liner has failed and you’re worried about using your fireplace, call (571) 376-7052. A live person picks up. If the situation is a fire risk or a carbon monoxide concern, we’ll give you immediate guidance and schedule an inspection as fast as our schedule allows, and we’ll tell you what not to do in the meantime. We don’t charge extra for urgency, and we’ll never rush a job to meet a made-up deadline.
You get two warranties: the manufacturer’s warranty on the liner or repair materials, and our 365-Day Done Right Promise that covers the workmanship. If it’s not done right, we come back and make it right, period. Both warranties are written, and both are in your documentation packet before the job starts, because Haven Standard Clause 1 says everything gets written down before anyone picks up a tool. Corrine Halstead’s name is on every quote that leaves our Rockville office.
Clear the area within about 10 feet of the fireplace and move anything fragile off the mantel before we arrive. We’ll protect your floors and furniture with drop cloths and plastic sheeting, but clearing the space helps us work faster and keeps your belongings safe. If you have pets, keep them in a separate room during the work. We’ll confirm the appointment window and send a text when the tech is on the way, so you know it’s us at the door.
