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.

AfterFast, Reliable Chimney Repair Across Bethesda
Chimney repair in Bethesda typically runs between $400 and $4,500, depending on what the camera finds. A mortar repointing job on a single flue often lands near $800-$1,600, while a full chimney rebuild on a 1940s Colonial can exceed $12,000. We work throughout Bethesda, from Edgemoor to Kenwood to Bannockburn, and we schedule repairs within days, not weeks. If you’re looking at water staining, spalling brick, or a chimney that hasn’t been touched since the Eisenhower administration, call (240) 220-9395 for a written estimate. Corrine Halstead and our Chimney Repair team know these houses because we’ve been inside thousands of them since 2009.
Why Level Two Chimney Gaithersburg Is Bethesda’s Preferred Chimney Repair Company
Bethesda homeowners tend to be exacting. They want to see what we saw, in photos, before they spend a dollar. That’s how we’ve operated since 2009, and it’s why Clause 4 of the Haven Standard requires a documented photo record on every single job. We don’t tell you the flue is cracked. We show you the crack, explain what it means for drafting and moisture, and hand you a written price for the repair before any work begins. Not after.
Our crews spend a lot of time in Bethesda, particularly in the older sections east of Wisconsin Avenue where the housing stock is solid but the chimneys are original. Multi-flue masonry stacks, clay tile liners, corbeled crowns, failed dampers. We see them every week. Dispatch and scheduling are coordinated from our Washington, DC office, and our technicians are background-checked, uniformed, and licensed. When they’re on the way, you get a text with a name.
We answer the phone with a live person, 24/7. Not a voicemail tree. If you call at 9 p.m. because water is dripping into your living room through the fireplace, a person picks up.
Our Chimney Repair Services in Bethesda
Mortar Repointing
Bethesda’s freeze-thaw cycles push moisture into old lime mortar and pop it loose, piece by piece. In the 1930s-1950s Colonials and Tudor Revivals around Edgemoor and Kenwood, the original mortar is often 60 to 80 years old and softer than modern brick. Repointing, also called tuckpointing, removes the decayed mortar to a proper depth and packs in a matched mix that flexes with the freeze-thaw rhythm. On a typical Bethesda chimney, repointing runs $800-$1,600 per flue face, and the difference is visible in the first winter after it’s done. No more spalled chips on the lawn.
Spalling Brick Repair
Spalling is what happens when water gets behind the brick face and freezes. The face of the brick pops off, sometimes in chunks the size of a silver dollar. On Bethesda chimneys, the pattern is consistent: north-facing faces hold moisture and spall first, and humid summers encourage moss that traps water against the brick. We cut out the damaged units, replace them with new brick matched to your color and texture, and address the water entry point so it doesn’t happen again. A single spalled section is usually $500-$1,200. A chimney with spalling on three sides of the crown points to a larger water problem, and we’ll tell you that plainly before quoting anything.
Chimney Waterproofing
Bethesda gets over 40 inches of rain a year, and the masonry on pre-1960s chimneys is thirsty. Waterproofing isn’t some spray-on sealant that cracks next spring. We use vapor-permeable treatments like ChimneySaver that let the brick breathe while keeping water out, but the real fix is a full crown repair first. A sound waterproofing treatment on a Bethesda chimney runs $600-$1,400, and we document the surface readings before and after. If the crown is shot, waterproofing alone won’t save you. We’ll show you the crown photos and let you decide.
Flashing Repair
Flashing leaks are the most common cause of water damage we trace in Bethesda homes. The original copper or galvanized flashing on a 1950s Colonial in Wyngate or Ashburton is often worn through at the seams or pulled away from mortar that has crumbled. The water follows the chimney through the roof line, and by the time you see a stain on the ceiling, the flashing has been failing for months. We replace step flashing, counter flashing, and the cricket where needed. Typical flashing repair in Bethesda runs $700-$1,500, and we photograph every seam before we close it up.
Chimney Rebuilding
When the crown has crumbled, the bricks below it are moving, and three sides of the stack are spalled, rebuilding is the honest call. We rebuild from the roofline up, reusing what’s salvageable and setting a new poured crown with a proper drip edge. On a Bethesda house, this is usually $4,500-$12,000 depending on height, access, and the condition of the flue liners. We know that’s a serious number. That’s why we never recommend it without a camera scan, a written scope, and photos you can keep. Corrine Halstead reviews every rebuild quote before it goes out.

BeforeAfterTrusted Brands We Service in Bethesda
We don’t install whatever’s on the truck. For Bethesda chimneys, we source materials from manufacturers like Olympia Chimney, Famco, and Copperfield through Haven’s buying network. That keeps the material costs honest on your end. Whether it’s a new chimney cap, a replacement damper, or a stainless liner for a gas conversion, the part is on our truck within a day or two, not two weeks. Most Bethesda repairs are completed in one visit.
Common Chimney Repair Problems We See in Bethesda Homes
- Failed gas conversions in unlined flues. In the 1980s and 1990s, a lot of Kenwood and Edgemoor homeowners switched their wood-burning fireplaces to gas but kept the original clay tile flue. Current Montgomery County code requires a properly sized liner for gas appliance venting. This shows up at sale, and it’s expensive to argue with.
- Cracked clay tile liners discovered at pre-sale inspection. We scan dozens of Bethesda chimneys every year where the sellers had no idea the liner was cracked. A Level 2 inspection finds it, the buyer’s inspector flags it, and suddenly there’s a $4,000 reline on the negotiating table.
- Corbeled crowns losing their mortar in freeze-thaw. The decorative corbels on 1930s-1950s chimneys are beautiful. They’re also a water trap. Moisture settles in the joints between corbels, freezes, and slowly pries the courses apart. By spring, chunks are missing.
- Water staining from failed flashing on rear-facing chimneys. Bethesda’s rear elevations often get more weather exposure and less attention. By the time a buyer notices the stain on the second-floor ceiling, the flashing has been open for a season or two.
Pricing for Chimney Repair in Bethesda, MD
Here’s what you’re looking at in Bethesda, in real numbers. A camera-scan inspection under NFPA 211 Level 2 runs $249, and we apply that toward any repair we do on the same visit. Mortar repointing: $800-$1,600 per flue face. Spalling brick replacement: $500-$1,200. Flashing repair: $700-$1,500. Waterproofing after crown repair: $600-$1,400. HeatShield resurfacing of a deteriorating clay liner: $3,800-$6,500. Full chimney rebuild from the roofline up: $4,500-$12,000. A partial rebuild of the top 10-15 courses: $2,800-$5,500.
What moves the price: chimney height, roof access difficulty, condition of the existing liner, and whether we’re working on one flue or a multi-flue stack. A single-flue cape in Bannockburn is a different job than a four-flue Colonial in Edgemoor. We give you the written price after the camera comes back up, not before we’ve seen anything. And if you’ve got a written estimate from another company, bring it. We’ll give you a free second opinion on it.

FAQs - Chimney Repair in Bethesda
Because the code changed, and the chimneys didn’t. Bethesda’s 1930s-1950s Colonials were built with clay tile flues that were fine for wood burning in 1955. Many were converted to gas in the 1980s and 1990s without relining, which violates current Montgomery County venting code. A Level 2 camera scan is the only way to see inside the flue and confirm what’s actually there. Buyers are asking for it. Sellers are getting caught by it. The inspection fee is cheap compared to the reline bill either party might end up holding. Call (240) 220-9395 to schedule one before your listing photos are even taken.
Yes, in most Bethesda homes we can. If the masonry structure is sound, we install a properly sized stainless liner or apply a HeatShield resurfacing system inside the existing flue. We did exactly this on a Tudor Revival in Kenwood earlier this year: the original clay tile flue had a third-degree creosote tar glaze from decades of wood burning before the gas conversion. We removed the failed damper, resurfaced the flue with HeatShield, and rebuilt the spalled crown. The whole job was done before the buyer’s inspection contingency expired. If the brick itself is moving, a partial rebuild may be necessary, but we won’t recommend that without showing you the camera footage.
Water gets into the brick, freezes, and pops the face off. Bethesda’s location in the mid-Atlantic freeze-thaw belt means 30-50 freeze events every winter, plus humid summers that encourage moss on north-facing brick. The repair involves cutting out the damaged brick, setting in new units matched to your home’s color and texture, and fixing the water source, which is usually a failed crown or open mortar joints. We photograph every step of the repair. If you see brick chips in your garden or on your porch roof, call us before another winter does more damage.
Once a year, and more often if you burn wood in any of them. A house in Kenwood with three flues is three separate chimney systems sharing one masonry structure. A crack in one flue can send combustion gases into the other. The National Fire Protection Association recommends an annual inspection, and with Bethesda’s freeze-thaw cycles, that’s not conservative. It’s the minimum that makes sense. We scan the full stack, photograph every flue, and tell you what needs attention now and what can wait. Call (240) 220-9395 for a written inspection report you can keep.
Because the flue and the masonry don’t care what fuel you burn. A gas fireplace produces acidic exhaust that corrodes clay tile liners over time, and the chimney still sits outside in Bethesda’s weather. The crown still cracks. The flashing still leaks. The bricks still spall. And in many Bethesda colonials, the gas appliance was never properly lined to begin with. An annual inspection catches the liner corrosion before it becomes a drafting problem or a carbon monoxide risk. If your gas fireplace was converted decades ago and the flue has never been scanned, that’s the first thing we’ll check.
