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
A Rockville Chimney Liner & Rebuild runs anywhere from $1,800 for a straightforward stainless steel liner install to $9,000 or more when the masonry needs to be taken down and rebuilt from the roofline up. The reason the range is that wide is simple: every chimney hides its own story, and until Wendell Pike gets a camera up there, nobody can tell you for certain what yours needs. That’s the whole point of how we work at Top Hat Chimney. Since 1999, Wendell has been the guy Rockville homeowners call when a national chain quoted them one number on the phone, sent a stranger to the door, and left behind a mess and a bill that didn’t match anything they were promised.
We’ve spent over 29 years crawling through flues in Montgomery County, and the liners we pull out tell us everything. A cracked clay tile liner doesn’t argue with you. A rusted-through steel liner from a 1980s install doesn’t either. What you’ll get from us is a straight answer, backed by video footage you can watch yourself, before a single tool comes off the truck. That’s how we’ve always done it. Call Wendell at (240) 716-5865 and you’ll talk to a live person, not a call center, and often enough it’ll be Wendell himself.
What Our Chimney Liner & Rebuild Service Includes
When someone says “chimney liner and rebuild,” they’re usually talking about one of several different jobs, each with its own price point and its own urgency. At Top Hat Chimney, we won’t sell you a rebuild when a liner swap gets the job done, and we won’t paper over a structural problem with a patch that buys you two seasons and a false sense of security. Here’s what falls under our chimney liner and rebuild service in Rockville, plain and simple.
Stainless Steel Liner
A stainless steel liner is a continuous metal tube that runs from your appliance or fireplace up through the flue and exits at the top. It’s the modern standard for venting gas and oil appliances, and it’s what we recommend for most wood-burning masonry fireplaces that have lost their original clay tile liner. At Top Hat Chimney, we measure, cut, and install the liner to fit your specific flue dimensions, not a one-size-fits-most kit that rattles around and leaves gaps. Every stainless liner we install for Rockville homeowners is sized properly and secured at the top with a cap that keeps rain and critters out.
Flexible Liner
Flexible liners are exactly what the name says: a corrugated stainless steel or aluminum tube that can bend around the curves and offsets inside older chimneys without tearing out masonry. They’re the go-to when your flue makes a turn that a rigid liner can’t follow. Wendell has installed flexible liners in some of the oldest homes in Rockville, where chimneys were built long before modern appliances and the flue path is anything but straight. We’ll show you the camera footage so you can see exactly why the flexible option made sense for your chimney and not just take our word for it.
Liner Replacement
If you already have a liner and it’s cracked, rusted, or separated at the seams, you’re looking at a replacement, not a repair. Liner replacement means pulling the old one out, cleaning the flue down to bare surface, and installing a new liner sized to your current appliance. We replace liners in gas, oil, and wood systems all over Rockville, and the most common thing we hear afterward is, “I didn’t realize it was that bad.” The camera footage and a plain-English verdict, every time, no exceptions. That’s the rule.
Partial Rebuild
A partial rebuild addresses the portion of the chimney that’s failing, usually the crown, the top few courses of brick, or a section above the roofline that’s taken decades of freeze-thaw cycles and spalling. You don’t always need the whole thing torn down. When a partial rebuild is the right call, Wendell will tell you exactly which courses are coming out, why they’re coming out, and what’s going back in. We’ll match the mortar and brick as closely as we can, and we’ll stand behind the work with the 90-Day Done Right Promise in writing.
Full Chimney Rebuild
When the structural integrity is gone from the roofline up, or when the flue has collapsed internally, a full chimney rebuild is the only responsible answer. That means taking the chimney down to a stable point and rebuilding it with proper flashing, a poured crown, and a new liner system. It’s the biggest job we do, and it’s the one where honesty matters most. If your Gaithersburg Chimney Liner & Rebuild or Rockville chimney needs a full rebuild, we’ll show you why with pictures and video, give you a number that doesn’t change, and do the work with the same care Wendell brought to his first job in 1999.
Liner Repair
Not every liner problem requires a full replacement. Small cracks in clay tile liners, minor separation at the joints, and isolated rust-through spots can sometimes be addressed with a targeted repair. In many cases we use HeatShield’s Cerfractory sealant system, which meets the same safety standards as a new stainless liner at a lower price point and with a lot less disruption. Wendell is a HeatShield certified installer and has been using their system in Rockville homes for years. He’ll tell you honestly whether a repair will hold or whether you’re throwing money at a problem that’s coming back in three years.

Brands We Service for Chimney Liner & Rebuild
We install and service liners from the brands that have proven themselves in Maryland’s freeze-thaw climate, and we don’t stock junk. HeatShield is our go-to for ceramic sealant repairs and resurfacing systems, and we’ve been a certified installer for so long that when Rockville homeowners call asking about it by name, Wendell can usually tell them exactly what their chimney needs before he even gets on the ladder. The Cerfractory material they make is rated to 2900 degrees Fahrenheit and carries a 20-year manufacturer warranty, which is about as good as this industry offers.
Our flexible liner work runs heavy on Gelco and Olympia Chimney, both of which build UL-listed liner systems that hold up to the acidic byproducts of gas appliances and the creosote loading of wood stoves. We’ve installed Famco caps and dampers on rebuilt chimneys all over Rockville, and we keep their parts in the truck so we’re not making second trips because we forgot a top plate. Whatever brand is in your chimney now, or whatever brand you’ve been told you need, we’ll tell you straight whether it’s the right product for the job or whether someone was just moving inventory.
Signs You Need Chimney Liner & Rebuild Right Now
Your flue doesn’t care how the fire looks. It cares how it breathes. Most liner failures happen slowly, over years, and the signs are easy to write off as normal wear and tear. Here’s what we tell Rockville homeowners to watch for, and why each one matters.
- Flakes of tile in the firebox. If you’re finding thin, flat pieces of clay tile, or a fine sandy grit, in the bottom of your fireplace, your liner is actively deteriorating. Those pieces used to be the barrier between the fire and the brick. As the liner goes, the flue gets wider and the draft gets weaker, which means more smoke in your living room and more creosote building up in the now-roughened flue walls.
- White staining or efflorescence on the exterior brick. That white powdery crust is water moving through the masonry, carrying salts out of the mortar and brick. It means water is getting into places it shouldn’t be, and inside the flue, water plus heat equals spalling and liner cracking. Chimneys break in the off-season too, and often the first visible sign is on the outside brick.
- A rusted damper or water in the firebox after rain. Water coming down the flue isn’t just an annoyance. It’s a sign that the liner has cracked, the crown has failed, or the cap is missing. Rust on the damper tells you this has been happening for a while. A wet flue is a damaged flue, and the damage compounds every freeze cycle we get in Rockville.
- Smoke backing up into the house, or a fireplace that’s harder to start than it used to be. A cracked or collapsed liner changes the draft dynamics of your entire chimney. When the flue can’t maintain a proper draw, smoke finds the path of least resistance, and that’s often your living room. It’s also a carbon monoxide risk with gas appliances, and that’s not a problem you want to diagnose by feel.
- A neighbor’s chimney was rebuilt and yours is the same age. Ask anyone on your street. Homes in neighborhoods like Aspen Hill and Glenmont were built in the same decade by the same crews using the same materials. If a neighbor’s liner failed, yours is probably close behind. It’s not a guarantee, but it’s a reason to get a camera in there and look.
If any of these sound familiar, call us at (240) 716-5865. We’ll schedule a camera inspection and show you exactly what’s happening before we recommend a single dollar of work.
Our Chimney Liner & Rebuild Process - Step by Step
We’ve done enough liner installs and rebuilds in Rockville to know that the work goes better when you know what’s happening and why. Here’s how it goes with Top Hat Chimney, start to finish.
- 1
Camera inspection first, always. Before we quote anything, a camera goes up the flue and the footage comes back down on a screen you can watch. You see what we see: the cracks, the rust, the gaps, the missing mortar. We’ll give you the plain-English verdict and a written recommendation. If the chimney doesn’t need work, that’s what we’ll tell you. Free second opinion on any written estimate from another company, no strings.
- 2
Written, fixed price before work starts. The number you hear on the phone is the number on the invoice. Before a single tool comes off the truck, Wendell will walk you through the scope of work, the materials going in, the timeline, and the price. We don’t change numbers at the door, and we don’t find “unexpected problems” that triple the cost halfway through. If we find something unexpected, you’ll see it on camera and decide how we proceed.
- 3
The work itself, done by a crew that knows your chimney. For a liner replacement, that means cleaning the flue, sizing the liner properly, dropping it down, and securing it top and bottom. For a rebuild, it means scaffolding, demolition, brick matching, and a poured crown that actually sheds water. Wendell and his crew do the work. Background-checked, uniformed, and they’ll give you a real arrival window and call if anything slips.
- 4
Before-and-after camera verification. When the job is done, we run the camera again and show you the finished product. A new liner should look like a clean metal tube from top to bottom. A rebuilt chimney should look like it belongs on the house. You get the footage, because it’s your chimney and you should know what’s up there.
- 5
The 90-Day Done Right Promise, in writing. Every completed job gets it, no exceptions. If the work isn’t right, one call brings Wendell back at no additional cost. He puts his name on the work, and he runs into you again on Saturday. That’s how it works when the owner is the one accountable.
How Much Does Chimney Liner & Rebuild Cost in Rockville?
A typical stainless steel liner replacement in Rockville runs between $1,800 and $3,500 depending on the flue height, the liner diameter, and whether we need to remove an old liner first, which is part of how much Chimney Liner & Rebuild costs overall. Flexible liner installations fall in the same range, with the lower end for straightforward gas appliance vents and the higher end for wood-burning systems that need insulation wrap. A partial rebuild, typically the top four to eight courses of brick plus a new crown, starts around $2,500 and can reach $5,000 if the flashing needs to come out and be redone. A full chimney rebuild from the roofline up runs $7,000 to $12,000 or more depending on height, access, and brick matching.
What affects the price more than anything is what we find when the camera goes up. A liner replacement in a 1960s Rockville split-level is usually straightforward. A Potomac Chimney Liner & Rebuild on a three-story colonial with difficult roof access is a different job entirely. That’s why we don’t quote over the phone without seeing the chimney. The estimate is free, it’s in writing, and it doesn’t come with a pressure close. We’d rather you take three days to think about it than feel pushed into a job you didn’t fully understand.
To avoid overpaying: get the camera footage, ask for a written scope of work, and compare the materials being quoted. A cheap aluminum liner isn’t the same product as a UL-listed stainless liner. If someone’s number is half of ours, ask them what they’re installing and what warranty backs it. We’re also glad to take a look at any written estimate you’ve received from another company and give you an honest second opinion, free. Standing offer. And remember: $40 off any repair over $200, no trip charge inside the county, and 10% off always for seniors and veterans.

Frequently Asked Questions - Chimney Liner & Rebuild in Rockville
A chimney liner is the inner tube, usually clay tile or stainless steel, that lines the inside of your flue and separates the heat and exhaust from the surrounding brick. A rebuild is what happens when the masonry itself, the brick and mortar on the outside of the chimney, has failed badly enough that it needs to be taken down and rebuilt. Sometimes a chimney needs only one of these; sometimes a deteriorating chimney needs both. At Top Hat Chimney, we figure out which is which with a camera, then show you the proof.
A straightforward stainless or flexible liner replacement takes one day, including setup, the old liner removal if needed, installation, and cleanup. A partial rebuild is usually two to three days depending on how much masonry is coming out and how accessible the chimney is. A full chimney rebuild takes one to two weeks, mostly because the mortar has to set properly between phases and the weather has to cooperate. We’ll give you a timeline in writing and call if anything changes.
Most homeowners in Rockville pay between $1,800 and $3,500 for a liner replacement, depending on the flue height, whether it’s a rigid or flexible liner, and whether insulation is needed. A partial rebuild with a new liner runs $4,000 to $7,000 in most cases. A full rebuild is the big one, $7,000 to $12,000 plus. The free estimate we give you includes a written scope and a fixed price, so you’ll know your number before any work starts. Call (240) 716-5865 to schedule the camera inspection that makes the estimate possible.

If you have an active chimney fire, call 911 first. If you’ve got a damaged liner that’s been flagged as unsafe and you need it addressed quickly, call us at (240) 716-5865 and we’ll get you on the schedule as soon as Wendell can get a camera up there. Our phones are answered by a live person 24 hours a day, 7 days a week. We don’t farm calls out to a call center, and it may well be Wendell himself who picks up.
Every liner install and rebuild we do in Rockville gets the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Wendell back.

Ask us for the specifics on your job and we’ll put it in writing alongside the price.
For a liner replacement, move anything fragile off the mantel and clear a path from the front door to the fireplace. For a rebuild, expect scaffolding on the exterior and keep the area around the chimney clear of furniture, planters, or anything you don’t want covered in fine brick dust. We’ll bring drop cloths and do a full cleanup before we leave. We’ll also give you a call the day before to confirm the arrival window and remind you of anything that applies to your specific job.
