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.

Why Level Two Chimney Rockville Is Bethesda’s Preferred Chimney Repair Company
We named our company after the standard that matters: NFPA 211 Level 2, camera down the flue, a written price before work starts, and a documented record when it’s done. Our Chimney Repair team has been doing that in Bethesda since 2009. For homeowners in Chevy Chase and Edgemoor, that means something specific: a technician who shows up, runs the camera, and shows you the footage before recommending a single repair. No one should be asked to approve a $4,000 liner job on faith.
Corrine Halstead, who leads our operation, made camera-scan documentation the default long before real estate agents in Bethesda started requiring it for pre-listing inspections. In this market, a written inspection report with photos is not an upsell. It’s what the closing attorney expects.
We answer the phone with a live person, 24 hours a day. When you call (571) 376-7052, you get a schedule, a named technician, and a text when the truck is on its way to your street in Bethesda. Uniformed, background-checked crews. License information is on every estimate. The 365-Day Done Right Promise applies to every job, and Clause 1 of the Haven Standard requires that your price be in writing before anyone picks up a trowel.
Our Chimney Repair Services in Bethesda
Mortar Repointing
Repointing in Bethesda is the repair most older brick chimneys eventually need. The freeze-thaw pattern around Bethesda, where winter storms regularly cycle the temperature across 32°F, works water into mortar joints and pops them apart over a decade or two. We cut out the failed joints and repack them with a mortar matched to your brick’s original strength and color. In neighborhoods like Edgemoor and Somerset, that color match matters visually, and we take the time to get it right.
Spalling Brick Repair
Spalling is what happens when trapped moisture freezes and shears the face off a brick. We see it on Bethesda’s exposed chimney stacks where a cracked crown or failed flashing has been letting water in for years. The repair is straightforward: remove the compromised brick, install replacement material, and address the moisture source that caused it. Patching spalled brick without fixing the water entry point is the kind of work we won’t do here. It fails again.
Chimney Waterproofing
Waterproofing is one of the most underused repairs in Bethesda, and it shouldn’t be. A breathable masonry water repellent, properly applied after other repairs, stops most freeze-thaw damage before it starts. We recommend it on nearly every older brick stack in Bethesda because the DC-area climate simply gives masonry too many wet, cold days each winter. The two most common points of water entry are the chimney crown and the flashing where the stack meets the roof.
Flashing Repair
Flashing failure in Bethesda’s older homes accounts for a good share of the chimney leaks we track down each winter. Original flashing on a 1930s or 1950s Colonial is often galvanized steel that has rusted through. We replace it with copper or heavy-gauge aluminum stepped flashing, counterflashed into the mortar joints. If you’ve got water staining on the ceiling near a fireplace, call us at (571) 376-7052 before you assume it’s the roof.

That means we stock common liner components and repair materials locally for faster turnaround in Bethesda, so a heat-shield resurfacing job or a DuraFlex liner install doesn’t stall waiting on a parts shipment. No brand worship here: we use what the condition of your flue dictates, and we’ll tell you exactly which product and why, in writing.
Common Chimney Repair Problems We See in Bethesda Homes
- Oversized legacy flues. In Bethesda’s older neighborhoods like Chevy Chase and Edgemoor, original clay-tile flues from coal-era masonry chimneys are frequently oversized for modern gas inserts. That causes poor draft and moisture accumulation, and the fix is resizing with a properly rated liner, not only a sweep.
- Spalled terra-cotta flue tiles. Decades of heating and cooling cycles leave clay tiles cracked, offset, or missing sections. A Level 2 video inspection shows exactly where the failure is, and repairs like a DuraFlex stainless liner restore safe draft.
- Freeze-thaw crown and mortar damage. Exposed brick stacks on Bethesda’s Colonials and Tudors take the brunt of every winter. Crown cracks and eroded mortar joints let water in, and the repeated freeze-thaw cycle slowly destroys the structure from the inside.
- Flashing leaks on multi-fireplace homes. Bethesda’s larger homes often have two, three, or four fireplaces on separate flues. More flashing, more crowns, more places for water to find a seam. When one leaks, the others are usually close behind.
Pricing for Chimney Repair in Bethesda, MD
Here are the ranges we quote most often in Bethesda, Maryland:
- Mortar repointing: $450-$1,400, depending on chimney height, access, and how much joint work is needed.
- Spalling brick repair: $300-$900 per affected area, plus any crown or flashing repair that addresses the moisture source.
- Chimney waterproofing: $350-$700 for a standard one- or two-flue stack, including cleaning and prep.
- Flashing repair or replacement: $500-$1,600, depending on whether it’s a small patch or full step flashing around a multi-flue chase.
- Flue liner installation (DuraFlex stainless or HeatShield): $1,800-$3,500 for a typical Bethesda masonry chimney, including removal of failed tile where needed.
What moves the price in Bethesda is chimney height and the condition of the existing flue. A three-story Edgemoor chimney with failed terra-cotta tile will cost more to reline than a shorter, simpler stack in a 1980s subdivision. That’s why we put a camera down first. You get a written scope, a written price, and a written warranty before anyone starts, and the quote is free. Call (571) 376-7052 and bring us another company’s written estimate if you have one. We’ll give you a straight second opinion on it.

FAQs - Chimney Repair in Bethesda
Yes. Bethesda’s pre-1950 masonry chimneys, especially in Chevy Chase, Edgemoor, and Kenwood, were built for coal or wood-burning furnaces and later converted to gas inserts, leaving oversized clay-tile flues that draft poorly and trap moisture. Repairing these often means resizing or relining the flue, rebuilding the crown, and waterproofing the masonry - not only repointing the mortar. Newer zero-clearance units in rebuilt homes have different failure modes and different codes, so we always start with the camera. For a written quote, call (571) 376-7052.
Bethesda’s winter weather regularly crosses the 32°F threshold, which means water trapped in masonry freezes and expands, then thaws, every cycle. That repeated expansion is what spalls brick faces and breaks mortar joints. The practical effect: spring is the highest-demand window in Bethesda because homeowners discover damage after the heating season, and repairs should ideally be done before the next winter to prevent further cracking. If you can see flaking brick or an eroded crown now, don’t wait another cycle. Call (571) 376-7052 and we’ll schedule an inspection.
Yes, for us. NFPA 211 Level 2 inspection with a camera down the flue has been our default on every Bethesda job since 2009, and Clause 4 of the Haven Standard requires a documented photo record on every visit. In Bethesda, real estate agents and closing attorneys increasingly require a written camera inspection report as part of a sale, so doing the inspection without the camera would be doing half the job. You keep the images, the written scope, and the written warranty.
Oversized legacy flues. Bethesda’s larger pre-1950 homes in neighborhoods like Edgemoor and Chevy Chase often have multiple fireplaces on flues originally built for coal furnaces. When those systems were converted to gas inserts, the flue cross-section stayed too big, causing poor draft and condensation. That moisture shows up as efflorescence, eroding mortar, and in the worst cases, spalled tile. The fix is usually a correctly sized stainless steel liner. Our crew was called to a 1930s brick Colonial in Edgemoor where two original terra-cotta flue tiles had spalled after decades of freeze-thaw cycles. We installed a DuraFlex stainless steel flue liner, rebuilt the chimney crown, and waterproofed the exposed brick, restoring safe draft for the home’s three working fireplaces. Call (571) 376-7052 if you suspect something similar in your house.
As soon as the contract is signed. Bethesda’s luxury real estate market moves fast, and a buyer contingency inspection with a written Level 2 camera report is now routine, especially in Chevy Chase, Edgemoor, and Kenwood. If you’re selling, getting the chimney inspected and repaired before listing eliminates a deal-killing surprise. If you’re buying, the inspection shows you exactly what the flue, crown, and flashing need before you close. We schedule on short notice for Bethesda closings. Call (571) 376-7052 and Corrine Halstead’s team will get you on the calendar.
