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 Manassas Homeowners
When a chimney liner fails, the problem is rarely visible from the hearth. The flue tiles crack, the mortar joints erode, and the clay liner that once carried smoke safely out of your Manassas home becomes a fire hazard hidden inside the masonry. At Level Two Chimney Manassas, we identify liner damage with a camera before we recommend anything, and we give you a written price, written scope, and written warranty before any work starts. Led by Corrine Halstead and backed by 38,000+ chimney inspections since 2009, we serve Manassas, Fairfax, Reston, and the surrounding Northern Virginia area. Call (571) 946-2300 to schedule an inspection.
Most Manassas Chimney Liner & Rebuild jobs cost between $2,400 and $6,800 depending on flue length, house height, and whether the crown needs rebuilding at the same time. That’s the honest range. We’ll give you the exact number in writing before you decide anything.
What Our Chimney Liner & Rebuild Service Includes
Liner and rebuild work covers a range of conditions, from a single cracked flue tile to a chimney that needs to come down to the roofline and go back up. Here’s what each job entails and when each one applies to a Manassas home.
Stainless Steel Liner
A stainless steel liner is a continuous pipe installed inside the existing flue, usually for a furnace, boiler, or water heater vent. You need one when the original clay liner is broken or absent, or when a new high-efficiency appliance produces exhaust cool enough to condense inside an old masonry flue. We install rigid 316L stainless liners sized to the appliance’s BTU output, with a written sizing calculation included in your quote. It’s the long-term fix for a flue that can’t be restored with resurfacing.
Flexible Liner
Flexible stainless liners are used when the existing flue isn’t straight, which is common in older Manassas homes with corbelled or offset chimneys. The liner bends through the offset without requiring us to tear out masonry. We install flexible liners with a full-length insulation wrap that keeps flue gases hot enough to draft properly, a detail that matters in cold Virginia winters. The material itself comes from DuraFlex, and the installation always ends with a camera scan so you can see the full length before we call it done.
Liner Replacement
Liner replacement means removing the failed liner, whether it’s rusted metal or cracked clay, and installing a new one sized to the appliance. Symptoms that bring this up include flue tile fragments at the cleanout, rust streaks on the chimney exterior, or exhaust odors inside the house. We start with a Level 2 camera inspection to document the current condition, then give you a written comparison of your replacement options. Nothing gets recommended unless the camera shows us a reason.
Partial Rebuild
A partial rebuild addresses the section of a chimney that’s failing, usually the top few courses of brick, the crown, or the shoulder area above the roofline. Spalling bricks, a crumbling crown, and water intrusion at the roofline are all signs you may need this rather than a full rebuild. We rebuild to code, including a proper concrete crown with an expansion joint and overhang, and we document the work with photos before, during, and after. A partial rebuild in Manassas typically runs $2,800 to $6,500, depending on how far down the damage extends.
Full Chimney Rebuild
When the structural brickwork itself has failed, or when the fireplace needs to be relined end to end, a full rebuild is the answer. We take the chimney down to the point of sound masonry, rebuild with new brick or block, install a new liner, and pour a new crown. This is also when we address the smoke chamber: the transitional area above the firebox where smoke compresses before entering the flue, and where most drafting problems begin. A full rebuild with liner replacement in Manassas generally falls between $8,000 and $18,000, and you’ll receive a written line-item scope before we order materials.
Liner Repair
Not every liner problem is a full replacement. Minor gaps, separated joints, or small areas of spalling can be sealed with HeatShield, a ceramic resurfacing material we apply after cleaning the flue to a bare surface. This works when the damage is localized and the underlying structure is sound. We’ll tell you plainly when repair will work and when it won’t, and the decision is always backed by camera images you can see yourself. HeatShield repair in Manassas usually lands between $1,800 and $3,400.

Brands We Service for Chimney Liner & Rebuild
We install and service liners from the manufacturers that have earned their place in Northern Virginia’s climate. DuraFlex is our standard for flexible and rigid stainless liner systems because their 316L alloy holds up well to the sulfur byproducts produced by gas and oil appliances. Copperfield is our preferred line for chimney caps, crowns, and chase covers, especially on the light-gauge metal chases common in newer Manassas townhouse and colonial builds.
We inspect, repair, and rebuild chimneys built by any mason and vented with any liner. Whether you have a Gelco chase pan on a builder’s box or a HeatShield-resurfaced clay flue from a previous owner, we’ll document what’s there and give you a straight answer about what needs to happen next. The manufacturer matters less than the condition, and the condition is what the camera shows us.
BeforeAfterSigns You Need Chimney Liner & Rebuild Right Now
- Flue tile fragments at the cleanout door. Cracked clay tiles fall to the bottom of the flue as they fail. When we find tile shards during a cleaning, the liner has already lost its integrity, and using the fireplace before addressing it puts heat directly against combustible framing.
- Rust streaks or staining on the exterior brick. Moisture that gets inside the flue reacts with clay and mortar, producing rust-colored stains that seep through the masonry. By the time the staining is visible outside, the water damage inside is already advanced.
- Exhaust odor or smoke backing into the house. A compromised liner lets combustion gases leak into the wall cavity or living space. Carbon monoxide is colorless and odorless; the smell you detect may be the less dangerous component of a mixture that includes CO. If you’re smelling exhaust, treat it as urgent.
- Spalling brick and a crumbling crown. Water that freezes inside the masonry pushes brick faces off, a process called spalling. A deteriorated crown accelerates it by letting water directly into the chimney structure. This is the most common path to a partial rebuild in older Manassas homes.
- A chimney that hasn’t been inspected in more than two years. Most liner failures are found before they cause a problem, but only if someone looks. A Level 2 camera scan takes about 45 minutes and gives you either a clean bill or a clear picture of what’s failing. Given the cost difference between a liner repair and a house fire, it’s the most cost-effective hour a Manassas homeowner can spend on their fireplace.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Camera-scan inspection, NFPA 211 Level 2. We run a camera from the firebox to the flue top and record the full length. You’ll see the video with us and get the photos. This is Clause 4 of the Haven Standard, and it’s been our default on every job since 2009.
- 2
Written price and written scope. Before any work begins, you get a line-item price, a description of what we’ll do, and the warranty terms in writing. No estimate is verbal, and no work starts until you’ve approved the document. Clause 1 of the Haven Standard exists exactly for this.
- 3
Prep and protection. We cover the hearth with drop cloths, run a HEPA vacuum during any demo, and rope off the work area. Our technicians are background-checked, uniformed, and assigned by name; you’ll get a text when they’re on the way.
- 4
The rebuild or reline itself. Depending on the scope, this means removing the old liner, preparing the flue, installing the new system, and rebuilding any masonry that needs it. We torque every connection, insulate where design requires, and keep a photo log of the work in progress.
- 5
Post-work camera scan and documentation. When the job is complete, we run the camera again so you can see the finished liner from top to bottom. You receive the full photo record, the written warranty, and the final invoice. If anything isn’t right, the 365-Day Done Right Promise covers it.
How Much Does Chimney Liner & Rebuild Cost in Manassas?
A typical stainless steel liner replacement in Manassas runs $2,400 to $4,200 for a straight flue on a single-story home. Flexible liner installations for offset flues typically fall between $2,800 and $5,500. A partial rebuild with crown replacement and top-course brickwork usually lands between $2,800 and $6,500. A full chimney rebuild with a new liner runs $8,000 to $18,000 depending on chimney height, access, and the extent of masonry replacement.
What affects the price: flue length and diameter, roof pitch and chimney height, whether the crown and cap are replaced in the same visit, and whether interior wall repair is needed after the job. The best way to avoid overpaying is to get a written scope, not just a price, so you can compare what each company is actually doing. Our estimates are free, in writing, and they include the camera images that justify every line item. If you already have a written quote from another company, bring it in. We’ll give you a free second opinion on it.

Frequently Asked Questions - Chimney Liner & Rebuild in Manassas
A chimney liner is the inner surface of the flue that contains heat and combustion gases, and a rebuild is any structural repair to the masonry chimney itself. The two go together because a failing liner often destroys the chimney from the inside, and a failing chimney structure often damages the liner. At Level Two Chimney Manassas, our Chimney Liner & Rebuild in Fairfax and Manassas starts with a camera inspection that documents the condition of both.
Most stainless steel liner replacements in Manassas are completed in one day from setup to final camera scan. A partial rebuild with crown work typically takes two to three days, and a full chimney rebuild can take five to seven days depending on weather and height. We give you a schedule in writing before we start, and we don’t leave the job until the post-work camera scan is done and you have your photo record.
Liner replacement runs $2,400 to $6,800; partial rebuilds run $2,800 to $6,500; full rebuilds with a new liner run $8,000 to $18,000. Your exact cost depends on flue length, house height, offset count, and whether we’re rebuilding the crown in the same job. Call (571) 946-2300 for a free written estimate.
Yes. DuraFlex is our primary liner system for stainless steel applications, and we install Copperfield caps, crowns, and chase covers on our rebuilds. We also work with HeatShield for liner resurfacing and have installed Gelco components on existing chases. If you have a different brand, we’ll inspect it and tell you what it needs.
It can be. If you’re seeing flue tile fragments, smelling exhaust indoors, or the carbon monoxide detector near your fireplace has gone off, call us at (571) 946-2300 immediately and don’t use the fireplace until we’ve inspected it. Our phones are answered by a live person 24/7. For a liner that’s worn but not actively leaking, we can usually schedule within a week.
Every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. Your written warranty also covers materials and workmanship for the lifecycle stated on your quote, and the terms are given to you in writing before work begins. We don’t ask you to trust a verbal promise, and we don’t hold a warranty behind a renewal fee.
If we’re just inspecting, clear the area around the fireplace so we have room to work, and make sure a representative adult is home. If we’re doing the full liner or rebuild, we’ll handle the interior protection and cleanup, but you should remove anything valuable from the immediate hearth area. We’ll also text you when our technician is on the way, with the name of the person assigned to your job.
