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 Leesburg Homeowners
If you’re wondering how much Chimney Liner & Rebuild costs, Leesburg pricing typically runs between $2,800 and $12,000 depending on whether you need a stainless steel liner installed or a full masonry rebuild from the roofline up. Most liner replacements are completed in a single day; a full rebuild usually runs three to five days. Level Two Chimney Leesburg has inspected more than 38,000 chimneys since 2009, and every liner or rebuild job starts with a camera down the flue, a written price, and a written scope of work before anything gets touched. If you’re seeing crumbling mortar, rust flakes in the firebox, or you’ve been told your terra cotta liner is cracked, call (571) 601-3174 and we’ll put a camera in the flue and show you exactly what we see.
Corrine Halstead runs our Leesburg operation, and she’s built the crew around one rule: no recommendation without a photo the homeowner can look at themselves. That practice has been in place since our founding, and it’s written into Clause 4 of the Haven Standard, which requires a documented photo record on every single job. When we tell you a liner needs to be replaced, you’ll see the crack, the gap, or the spalling on a screen before you sign anything.
What Our Chimney Liner & Rebuild Service Includes
Every chimney liner and rebuild project in Leesburg gets the same starting point: an NFPA 211 Level 2 camera inspection that documents the condition of the flue, the smoke chamber, and the crown. From there, we quote the actual work in writing, using the photos as evidence. Nothing is recommended that can’t be shown to you. Here’s what we do, by the job:
Stainless Steel Liner
A stainless steel liner is a continuous metal tube installed inside your existing flue to contain heat and combustion gases when the original terra cotta liner has cracked or separated. In Leesburg, we commonly see this in homes built before 1990 where the original clay tiles have spalled from decades of freeze-thaw cycles. We install rigid and flexible stainless systems from DuraFlex, sized to the appliance and the flue dimensions, and we document the full length with a post-install camera scan so you can see the new liner seated correctly from top to bottom.
Flexible Liner
A flexible liner is a single continuous stainless steel tube, usually 316L alloy, that can be routed through an existing flue that has offsets or bends. It’s the most common solution when your chimney serves a gas appliance that’s being upgraded, or when an old liner has failed and the masonry around it is still sound. We pull the old liner if one is present, prep the flue, and run the new flex liner with proper top and bottom termination. Every flexible liner install includes draft testing and a camera verification pass before we call the job done.
Liner Replacement
Liner replacement means removing a failed liner, whether it’s cracked clay tile, a rusted-through steel pipe, or a deteriorated cast-in-place system, and installing a new one that matches the appliance and the home’s venting needs. The most common trigger we see in Leesburg is a furnace or water heater that’s been upgraded to higher efficiency and no longer drafts properly through the old flue. We remove the failed material where it’s safe to do so, run the new liner, and leave you with a photo record of the old and the new side by side.
Partial Rebuild
A partial rebuild addresses the section of the chimney that’s actually failing, typically the top few courses of brick above the roofline where wind, rain, and freeze-thaw hit hardest. In Chimney Liner & Rebuild - Sterling and Leesburg, we see a lot of spalling brick and separated mortar joints within the first five feet below the crown. We tear down to sound masonry, rebuild with brick matched as closely to your existing elevation as the market allows, and re-flash where the chimney meets the roof. If the flue liner in that section is also compromised, we’ll address it at the same time rather than making you tear things open twice.
Full Chimney Rebuild
A full chimney rebuild means taking the structure down to the roofline or below and rebuilding it with new brick, new mortar, a new flue liner, and a new crown. This is the right call when the masonry is deteriorated throughout, when structural cracks run deep, or when the chimney is leaning and no longer safe. We rebuild with proper corbeling at the top, a poured or form-built crown with a drip edge, and a liner system that meets current code. The job takes longer and costs more, but you end up with a chimney that’s warrantied in writing and documented with photos from the first brick to the last.
Liner Repair
Liner repair is a targeted fix rather than a full replacement, usually done when a section of the liner is cracked but the rest is intact. We use HeatShield, a cerfractory sealant system that’s applied with a spinning applicator inside the flue to restore a continuous, insulated surface. It’s a good option when the damage is localized and the underlying masonry is sound. If the camera shows structural failure or multiple cracks, we’ll tell you plainly that a repair won’t hold and recommend a replacement instead.

Brands We Service for Chimney Liner & Rebuild
We stock and install DuraFlex stainless liner systems for our Chimney Liner & Rebuild in Ashburn and the majority of our Leesburg liner replacements. DuraFlex makes a continuous, leak-resistant liner with a tight seam profile, and we’ve installed their systems in flues from a 4-inch gas appliance run up to a full masonry fireplace. Our techs are trained on proper sizing and termination, and we keep the common diameters on our trucks so a single-visit liner replacement is realistic for most homes.
We also work with Olympia Chimney products for caps, termination kits, and liner components, and we specify Famco and Copperfield parts where the job calls for them. Whether you have an older liner from one of these brands that’s failed, or you’re starting fresh with a new installation, our crews are familiar with the hardware and we don’t make a customer wait on a part we should have anticipated. If you’ve got a liner from any other manufacturer, the process is the same: camera first, written quote second, and no work until you’ve approved it in writing.
BeforeAfterSigns You Need Chimney Liner & Rebuild Right Now
- Flakes of terra cotta in the firebox - Those thin, curved shards at the bottom of your fireplace are pieces of your flue liner separating from the wall. It means the liner has already failed in at least one spot, and the gaps are allowing heat and gases to reach the masonry around it.
- Rust staining on the exterior brick or inside the firebox - Rust inside a chimney usually means a steel liner is corroding through, or moisture is getting in and attacking the metal components. Either way, the integrity of the flue is compromised, and moisture will keep doing damage until it’s addressed.
- Crumbling mortar joints and spalling brick above the roofline - Spalling is when the face of a brick pops off, and it’s a sign that water has penetrated and is freezing inside the masonry. In Leesburg’s winter climate, this failure mode is common, and once it starts, it accelerates. The top of the chimney is the first place it shows up.
- You can smell smoke or gas in the house after the fire is out, or when the furnace runs - A properly lined flue carries combustion gases all the way out. If you’re getting any backdraft smell inside, the liner isn’t doing its job, and that includes carbon monoxide risk from gas appliances. This is not a “keep an eye on it” situation.
- A home purchase inspection flagged the chimney - In Leesburg’s 2015 to 2025 buying wave, a lot of chimneys got flagged on inspection reports and then ignored. If you bought a home with a known liner issue and never addressed it, we can camera-scan the flue and tell you exactly what’s changed since that report, and what it costs to fix now.
If any of these are happening at your house, the next step is a camera inspection, not a guess. Call (571) 601-3174 and we’ll set a time to put a camera down the flue and show you what we’re seeing.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Camera inspection and photo documentation. We run an NFPA 211 Level 2 camera scan from the firebox to the top of the flue, and we photograph what we find. You’ll see the crack, the gap, or the rust with your own eyes. This is the evidence that drives every recommendation, and it’s included on every visit, not an add-on.
- 2
Written scope and written price, before anything starts. Clause 1 of the Haven Standard requires a written price, written scope, and written warranty before anyone touches your chimney. We’ll show you exactly what we’re proposing to do, what it costs in dollars, and how long it will take. You approve it, or you don’t. There’s no pressure.
- 3
Site protection and prep. We lay drop cloths from your door to the fireplace, cover the work area, and protect the surrounding floors. If we’re rebuilding above the roofline, we’ll stage materials safely and keep the roof clean as we go. Our techs are background-checked, uniformed, and you’ll know who’s coming before they arrive.
- 4
The work, done to code, with materials we can stand behind. Liner installs, repairs, partial rebuilds, and full rebuilds are done to current IRC and NFPA 211 requirements. We use materials from DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield, sourced through the Haven buying network to keep pricing honest. No shortcuts, no “that’ll probably hold” work.
- 5
Post-work camera verification and your photo record. When the job is done, we run the camera again so you can see the new liner or the rebuilt masonry from the inside. You get the full documented photo record, the written warranty, and the 365-Day Done Right Promise stamped on the work. If something isn’t right, we make it right.
How Much Does Chimney Liner & Rebuild Cost in Leesburg?
A stainless steel liner replacement in Leesburg typically runs $2,800 to $5,500, depending on flue height, liner diameter, and whether we’re relining a fireplace or a furnace flue. A partial rebuild that replaces the top few courses of brick plus the crown usually lands between $3,000 and $7,000. A full chimney rebuild from the roofline up starts around $8,000 and can reach $12,000 or more on a two-story chimney with significant masonry failure. Liner repair with HeatShield is usually the lowest-cost option at $1,200 to $2,800, but it’s only appropriate when the damage is localized. These are real numbers for Leesburg Chimney Liner & Rebuild, Ashburn, and Sterling markets, and they reflect what we’ve actually quoted in the past few seasons.
What changes the price: chimney height, roof pitch and access, the liner diameter your appliances require, and the extent of masonry damage that’s revealed once we open things up. What shouldn’t change the price: how busy we are. You’ll get the same written price in October or in February. To avoid overpaying, get a camera inspection with photos, and require a written scope. If a competitor gives you a written estimate, we’ll give you a free second opinion on it. Every estimate from us includes the camera scan, the written quote, and the time to walk you through both.
No one gets a price from Level Two Chimney Leesburg without the camera evidence behind it. If a company quotes you a liner replacement without looking inside the flue, that number is a guess. Call (571) 601-3174 and get a real one.

Frequently Asked Questions - Chimney Liner & Rebuild in Leesburg
A chimney liner and rebuild means repairing or replacing the flue liner that carries combustion gases out of your home, and repairing or rebuilding the masonry chimney that houses it. In a Leesburg home, the liner is the most likely point of failure after years of fire use and freeze-thaw cycles, and the rebuild addresses brick and mortar that have deteriorated. The two jobs often go together, because a failed liner accelerates masonry damage and vice versa.
A stainless steel liner replacement is typically a one-day job. A partial rebuild runs two to three days depending on weather and scope. A full chimney rebuild takes three to five days, including time for the new mortar to cure properly before the final camera pass.
Liner repair starts around $1,200, a full liner replacement runs $2,800 to $5,500, a partial rebuild is $3,000 to $7,000, and a full rebuild starts near $8,000 and can exceed $12,000 on tall chimneys with extensive damage. The only way to get an exact number is a camera inspection, because what’s inside the flue is what drives the real cost. Call (571) 601-3174 and we’ll give you a written price based on what we actually see.
We install and service DuraFlex liners regularly, and we also specify Olympia Chimney, Famco, and Copperfield parts where the job calls for them. If your home has a liner from another manufacturer that’s failed, the same process applies: camera inspection, written quote, and the right replacement for your appliance and flue size.
If you smell gas or smoke inside the house when a gas appliance runs or after a fire, that is an emergency, and you should call us at (571) 601-3174 right away. A crack that’s found on an inspection is urgent but not necessarily an emergency, and we’ll tell you which one you have honestly. Our phones are answered live 24/7, so you’ll always reach a person who can help you triage the situation.
Every liner and rebuild job comes with a written warranty on both materials and workmanship, and it’s backed by the 365-Day Done Right Promise: if it’s not done right, we make it right. The warranty terms are spelled out in writing before the work starts, and you’ll have the document in hand along with the photo record of the completed job.
Clear the area around your fireplace, move small furniture and décor out of the work zone, and make sure we have clear access to the roof if the job involves masonry above the roofline. We’ll protect the floors and the path from the door to the fireplace with drop cloths. If you have pets, put them in a separate room so the crew can work safely and your animals stay calm.
