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 Washington Homeowners
Chimney Repair in Washington, DC typically costs between $400 and $4,500 depending on what’s failing: a simple flashing patch runs $400 to $800, while a full chimney rebuild above the roofline can reach $4,500 in older Capitol Hill or Georgetown rowhomes. We’ve inspected and repaired more than 38,000 chimneys across DC, Maryland, and Northern Virginia since 2009, and every single job started with a camera-scan inspection and a written price before any work was approved. Corrine Halstead leads our Washington crew, and she’ll tell you the same thing we’ve told homeowners since day one: nothing gets recommended without photo evidence you can see for yourself. Call (240) 621-1264 for a free estimate, and we’ll put the price in writing before anyone touches a brick.
What Our Chimney Repair Service Includes
Chimney repair covers everything from the mortar joints holding your bricks together to the flashing that seals the roofline to the crown that keeps rain out of the flue. Washington’s freeze-thaw cycles, summer humidity, and old housing stock create specific failure patterns we see in neighborhoods like Capitol Hill, Georgetown, Brookland, and Cleveland Park. Here’s what we fix, in plain terms.
Mortar Repointing
Mortar Repointing is the process of grinding out deteriorated mortar joints and packing fresh mortar in. Washington winters force water into the joints, and when that water freezes it expands, cracking the mortar from the inside out. Our crews remove the old material to a proper depth, then repoint with mortar matched to your home’s original mix, so you don’t end up with a patchwork of mismatched colors across the chimney face. Most partial repointing jobs in DC rowhomes finish in a single day.
Spalling Brick Repair
Spalling is what happens when bricks absorb water and the face of the brick pops off or flakes away. You’ll see it as pitted brick surfaces or chunks of brick on the ground near the chimney base. We replace the damaged units with bricks matched to your existing masonry, and we address the moisture source so the new brick doesn’t fail the same way. Left alone, spalling progresses inward and can compromise the structural integrity of the chimney stack, which is why we document it during every Chimney Repair in Washington inspection.
Chimney Waterproofing
Chimney waterproofing applies a vapor-permeable water repellent to the masonry surface. The key distinction: it keeps rain out while letting water vapor inside the brick escape, which a waterproof paint or sealer won’t do. We apply it after any necessary repointing or brick replacement, because sealing over damaged masonry just traps moisture behind the barrier. In DC’s climate, where relative humidity averages 65 percent across the year, waterproofing extends the life of repointing work and reduces the frequency of future repairs.
Flashing Repair
Flashing is the metal barrier where the chimney meets the roofline, and it’s the single most common leak point we find in Washington homes. When flashing fails, water follows the chimney into the attic and down through wall cavities, often showing up as ceiling stains far from the chimney itself. We inspect the step flashing, counter-flashing, and the sealant condition, then repair or replace what’s actually failing rather than slapping silicone over the problem. A proper flashing repair in DC generally runs one to two hours once the crew is on the roof.
Chimney Rebuilding
Chimney rebuilding is exactly what it sounds like: taking down deteriorated masonry above a certain point and rebuilding it. In Washington, most rebuilds are partial, typically from the roofline up, where exposure to weather is harshest and the damage is concentrated. We rebuild with new brick or salvage what’s structurally sound, install a new crown, and document every stage with photos. Full rebuilds from the firebox up are rarer, and we’ll always show you why that scope is necessary before you commit, because this is the largest investment you’ll make in your chimney under most circumstances.
Tuckpointing
Tuckpointing is a specific style of repointing that creates the illusion of very fine mortar joints, common on historic brickwork. On Washington’s older rowhomes, especially in districts with design review requirements, tuckpointing preserves the visual character of the original masonry. We use the same tuckpointing technique as the historic builders: two contrasting mortar colors to create the thin joint line. Our crews familiar with DC historic preservation standards make sure the finished work doesn’t trigger a violation or look like a hasty patch job.

Brands We Service for Chimney Repair
When a liner or cap needs replacement, we source materials we trust: Copperfield stainless steel liners and caps, Famco caps and dampers, and DuraFlex chimney liners. We’ve specified Copperfield products on hundreds of Washington homes because their stainless and copper caps hold up to Mid-Atlantic weather without rust-through or warping, and their sizing runs true to spec, which matters when you’re dropping a liner 40 feet down a tight flue.
For most liner work in DC, we install DuraFlex stainless liners. They’re made in the US, carry a long manufacturer warranty, and their flexibility handles the angled flues common in older rowhomes. On repairs where the original liner can be saved rather than replaced, we use HeatShield resurfacing products, but we’ll always show you whether resurfacing is genuinely appropriate for the condition of the flue. Whether you have Copperfield, Famco, DuraFlex, HeatShield, or any other make, we can repair or replace it and we’ll bring the documentation to prove the materials meeting the manufacturer’s installation requirements.
BeforeAfterSigns You Need Chimney Repair Right Now
- Efflorescence, the white chalky staining on exterior brick. This isn’t a cosmetic nuisance; it means water is moving through the masonry and dissolving salts from the mortar. When efflorescence appears, moisture management has already failed, and the brick is taking on water. If you see it on your Washington chimney face, call for an inspection before winter freeze-thaw cycles worsen the damage, and remember repairs in Chimney Repair in Arlington face the same weather patterns or worse, depending on exposure.
- Rust on the fireplace damper or firebox. Rust inside the firebox means water is getting down past the crown or through failed flashing. That’s not a minor leak; it’s a sign your flue is exposed to rainwater, and moisture plus years of creosote makes for chimney fires and liner corrosion. We’ll source the entry point with a camera scan and give you a written repair plan.
- Spalling brick or mortar crumbs on the ground. We covered spalling above, but when you find brick flakes or grit collecting at the base of the chimney, the deterioration is active and progressing. In DC’s rowhouse neighborhoods, that damage often extends below the roofline, where it’s invisible from the ground. Early intervention costs hundreds, not thousands.
- Visible gaps in flashing or missing shingle tabs around the chimney. Flashing that’s pulled away from the brick or has visible sealant cracks is a leak waiting for the next heavy rain. DC gets an average of 40 inches of rain a year, and an open flashing gap can push water into your house during a single storm. We repair flashing with new metal, not caulk, and photo-document the finished product from the roof.
- Stains, dampness, or musty smell in the ceiling near the chimney. Leaks present as brown stains or bubbling paint on the ceiling or walls adjacent to the chimney chase. By the time you see staining, water has already infiltrated, and drywall and insulation may need replacing in addition to the chimney repair itself. We’ll locate the penetration point and put the entire repair scope in writing before starting.
Our Chimney Repair Process, Step by Step
- 1
Scheduling and arrival. When you call (240) 621-1264, a live person answers, not a voicemail. We schedule your appointment, assign a named technician, send a text when the crew is on the way, and arrive in uniform with their license number on the page and on their materials. Corrine Halstead personally reviews every repair job in Washington before the crew heads out.
- 2
Camera-scan inspection, NFPA 211 Level 2. Before any repair is proposed, we run a camera down the flue and document the condition of the liner, smoke chamber, damper, crown, flashing, and masonry. That’s Clause 4 of the Haven Standard: a documented photo record on every single visit. In DC’s older homes, we typically find a mix of original clay liners and newer stainless replacements with condition dictated by decades of heat and moisture.
- 3
Written scope and price. We put the entire repair scope in writing: what’s being fixed, the materials being used, the warranty that applies, and the exact dollar amount. You approve nothing until you’ve read it and asked your questions. This is Clause 1 of the Haven Standard, and it’s the reason we don’t work from verbal estimates or “we’ll know when we get in there” pricing.
- 4
The repair work itself. Your crew completes the repair using the materials specified, from mortar matched to your brick to the flashing metal and liner brands we named above. We keep you updated throughout the day and send photos from the roof and inside the flue as work progresses, so you can see the before, during, and after, even if you’re at work in Farragut or on a call from home in Tenleytown.
- 5
Documented closeout. When the job’s done, you get the full photo record, the written warranty, and confirmation that the work meets the manufacturer’s installation requirements. If anything isn’t done right within 365 days, the Done Right Promise means we make it right, no charge. That’s been our standard since 2009.
How Much Does Chimney Repair Cost in Washington?
A typical mortar repointing job in Washington runs $500 to $1,800, depending on the extent of joint and surrounding brick work. Flashing repair averages $400 to $800. Chimney waterproofing after repointing runs $300 to $600 on a standard rowhouse stack. Spalling Brick Repair averages $1,200 to $2,500, since it includes both brick replacement and the moisture-source correction. Partial chimney rebuilding from the roofline up runs $2,500 to $4,500 in most DC homes, with full rebuilds going higher. What affects the price: roof access and height (a four-story Georgetown chimney costs more to scaffold than a single-story bungalow in Brookland), the condition of the hidden structure we find during inspection, whether historic brick matching is required, and the brand of liner or flashing material you choose. How to avoid overpaying: ask for a written scope and a written warranty before anyone starts, and bring us a competitor’s written quote; we’ll give you a free second opinion. Every estimate we write includes the inspection, the photo record, and the specific materials by name. No exceptions.

Yes. We service chimneys with Copperfield caps and liners, Famco dampers and caps, and DuraFlex stainless chimney liners, and we stock their OEM parts. If your system includes any of these brands, our Washington crews understand their installation requirements and warranty terms. And if your chimney has no identifying brand or a brand we haven’t named, we can still repair it; the bigger question is the condition of the masonry and flashing around it, and we’ll show you that with the camera scan.
For safety issues like a collapsed flue liner, water actively pouring through a flashing failure, or a chimney fire that has compromised the structure, we’ll schedule you as quickly as possible. Our phone lines are answered by a live person 24/7, and we’ll get a crew out, but “same-day” is not a promise we can make for every scenario; we give you a written time window and we honor it.
