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 Repair for Rockville Homeowners
Our Chimney Repair in Rockville typically costs between $350 and $4,800 depending on what the camera finds, and most common repairs (flashing, repointing, crown work) are completed in a single visit. Since 2009, Level Two Chimney Rockville has repaired more than 38,000 chimneys across Montgomery County, every one documented with photos before and after. When water has been getting behind the brick or a liner has failed, waiting doesn’t make it cheaper. Call (571) 376-7052 and we’ll get a camera down your flue this week.
The name is the standard we work to: NFPA 211 Level 2. That means a camera down the flue, not a flashlight look from the roof. Corrine Halstead has run our Rockville operation on that principle, and every repair estimate has been a written price before work starts since day one. If you’re in Rockville, Gaithersburg, or Bethesda and suspect something is wrong, you’ll know exactly what we found, what it costs, and what we recommend fixing now versus what can wait.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar Repointing is the careful removal and replacement of deteriorated mortar joints between bricks. Rockville’s freeze-thaw winters split mortar open: water gets in, freezes, expands, and pushes the joints apart from the inside. We grind out the failed mortar to a consistent depth, match the original joint profile and color, and pack in fresh Type N mortar. The repair stops water intrusion at the surface and keeps the chimney structurally sound for another 20 to 30 years.
Spalling Brick Repair
Spalling Brick Repair addresses what happens when water trapped inside the brick turns to ice and pops the face off. You’ll see brick chips on the ground or a chimney that looks like its surface is peeling. In Rockville neighborhoods like Woodley Gardens and Manor Woods, we regularly see spalling on chimneys built in the 1970s and 80s. We remove the damaged brick, replace with matched units where possible, and address the water source so the same brick doesn’t fail again next winter.
Chimney Waterproofing
Chimney waterproofing is applying a breathable siloxane-based sealant that keeps liquid water out while letting water vapor escape. The key word is breathable. Paint-sealing a chimney traps moisture inside the masonry and accelerates spalling. We apply ChimneySaver or a comparable vapor-permeable product only after the masonry is clean and repairs are complete. A waterproofed chimney in this climate is the difference between a five-year repair cycle and a twenty-year one.
Flashing Repair
Flashing is the metal barrier where the chimney meets the roof line, and most chimney leaks in Rockville start there, not in the brick. If the flashing is lifting, rusted through, or was installed without proper step-and-counter flashing, water runs straight into the roof deck. We replace or reseal flashing with materials matched to your roof and confirm the repair with a water test. This is the most common repair we do, and it’s usually fixed in one visit.
Chimney Rebuilding
When more than about 30 percent of the brick face has spalled or the crown and top courses have lost structural integrity, we recommend a partial or full rebuild. This means taking down the damaged section, typically from the roof line up or from the throat up, and rebuilding it with new brick and Type N mortar. A rebuild in Rockville generally runs from $2,800 to $7,500 depending on height and access. We’ll show you camera footage first, and if the lower structure is sound, we won’t sell you a rebuild you don’t need.
Tuckpointing
Tuckpointing is technically a style of repointing where a thin lime line is cut into the mortar to mimic the look of old rubbed-brick masonry. People use the word loosely to mean any mortar repair. Around Rockville’s older sections and historic homes in West End, we do true tuckpointing when the look matters. Standard mortar restoration on newer homes, we call what it is: repointing.

Brands We Service for Chimney Repair
We work with HeatShield and the Gelco line on most liner and crown work. HeatShield cerfractory technology lets us resurface a damaged flue liner without a full tear-out in many cases, which saves Rockville homeowners thousands versus a total rebuild. We’ve installed and serviced HeatShield systems across Montgomery County and will always show you the camera footage before recommending it.
For caps, dampers, and top-sealing components, we commonly install Olympia Chimney and Famco hardware. Olympia’s stainless caps hold up well to the wet winters, and Famco dampers are what we reach for when a customer wants better air control. Whether you have one of these systems or something else entirely, our techs can diagnose and repair it. If you’re not sure what’s currently on your chimney, the camera inspection answers that in the first twenty minutes.
BeforeAfterSigns You Need Chimney Repair Right Now
- Water stains on the ceiling near the fireplace. This usually means flashing failure or a cracked crown, and it means water is already in your roof structure. The longer it runs, the more the repair expands from a chimney fix into drywall and insulation work.
- Brick chips or mortar crumbs at the base of the chimney. Spalling is a physical symptom of water inside the masonry, not surface wear. When the brick face starts popping off, the chimney is degrading from within, and Rockville’s freeze-thaw cycles will accelerate it every winter.
- A strong, tar-like smell from the fireplace in summer. That’s wet creosote off-gassing, which tells you water is getting down the flue. It’s also a sign that creosote is glazed and sitting against a liner that may already be compromised.
- White staining (efflorescence) across the brick face. Efflorescence is mineral deposits left when water evaporates out of the brick. It’s visual proof that water is moving through the chimney wall, and it won’t stop on its own.
- Rust on the damper or firebox. Rust means water has been coming down the flue long enough to corrode steel. If the damper is rusted through, there’s a good chance the liner above it has water exposure too.
Our Chimney Repair Process - Step by Step
- 1
Camera-scan inspection, before anything else. We run a commercial camera down the flue and photograph the entire interior. That’s NFPA 211 Level 2, and under Clause 4 of the Haven Standard, the photo record is yours to keep. You’ll see the liner condition, the smoke chamber, and the crown with your own eyes.
- 2
Written findings, written price, written scope. We hand you a document that says what we found, what repair we recommend, what it costs, and exactly what work the price covers. Clause 1 of the Haven Standard: everything in writing before anyone starts. If you bring us a competitor’s written estimate, we’ll give you a free second opinion on it.
- 3
Scheduled work with materials selected for the job. We pull materials from brands we know hold up in Mid-Atlantic weather: HeatShield for liners, Olympia Chimney for caps, Famco for dampers. No generic parts on a Level Two job.
- 4
The repair, done with protection for your home. Our techs arrive in uniform, background-checked, and you’ll get a text when they’re on the way. They protect the work area, work clean, and respect that it’s your home, not a job site.
- 5
Documented photo record when it’s done. We re-run the camera after the repair and hand you a photo record of the finished work, not just a receipt. That’s the 365-Day Done Right Promise: if it’s not done right, we make it right. Every repair has been documented this way since 2009.
How Much Does Chimney Repair Cost in Rockville?
A typical flashing repair in Rockville runs $400 to $900. Repointing starts around $600 and climbs based on how much of the chimney face needs work. A crown rebuild with proper expansion space is typically $1,200 to $2,400. Full rebuilds start around $2,800 and top out near $7,500 when access is difficult or the whole structure above the roof line is compromised. Liner repair with HeatShield runs $2,500 to $4,500 on average, while a full stainless liner replacement lands between $3,500 and $6,000 depending on the flue’s height and condition.
What moves the price? Access is the big one: roof pitch, chimney height, and whether we need staging or a lift. Material condition matters too. If the underlying brick is sound, repointing is cheap and effective. If water has been getting in for years, the repair is bigger. What’s included in your free estimate: the camera inspection, written findings, a line-item written price with scope, and a written warranty. No verbal estimates, no surprise line items added after we start. As Corrine Halstead says, if the price changes, the scope changes, and you’ll see it in writing first.

Frequently Asked Questions - Chimney Repair in Rockville
Chimney repair is structural or water-management work on the masonry, liner, crown, or flashing: repointing, spalling brick replacement, waterproofing, flashing reseal or replacement, liner repair, and full or partial rebuilds. The goal is always the same: keep water out, keep fire gases contained, and keep the structure sound. The only way to know which repairs you need is a camera-scan inspection, not a visual look from the yard.
Most repairs, including flashing replacement, repointing, and crown work, are done in a single visit of four to eight hours. A full rebuild takes two to three days. We’ll put a timeframe in your written scope before work starts, and we’ll text you when the crew is on the way.
Most repairs land between $350 and $4,800. Flashing is typically $400 to $900, repointing starts around $600, crowns run $1,200 to $2,400, and rebuilds start at $2,800. Your written estimate includes the exact scope, materials, and warranty, so there are no surprises. Call (571) 376-7052 for an exact quote: estimates are free.
Yes. We install and repair HeatShield cerfractory liner systems and stock their repair materials. If you have a HeatShield liner that’s not performing, our camera inspection tells us exactly what’s going on inside the flue, and we’ll repair it under the same written price, written warranty standard as everything else.
Some repairs are urgent, some are not. A gap in your flashing during a rainy week is urgent because the roof deck is getting wet. A small amount of efflorescence on the chimney face can usually wait until your next regular sweep. During the inspection, we’ll tell you plainly what needs attention now and what can wait, and we’ll put that down in writing. Live phone support is available 24/7 if you need a real person.
Every repair is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right. That means if a repair fails within a year, we come back and correct it. The specific warranty terms for your repair are in the written document you receive before work starts. No fine-print games, no verbal promises: it’s in writing.
Clear the area around the fireplace so we can access the firebox and run the camera up the flue. If the repair involves the roof, make sure gates are unlocked and dogs are secured if your yard has access. You don’t need to cover furniture: we protect the workspace with drop cloths and clean up when we’re done. A text will confirm when we’re on the way.
