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 Washington Is Washington’s Preferred Chimney Repair Company
We’ve worked on more than 38,000 chimneys since 2009, and a disproportionate share of the difficult ones are in Washington. That’s not a sales line. DC row houses, the 1880s-to-1910s brick stacks in Capitol Hill, Shaw, Petworth, and Georgetown, present repair challenges that a suburban split-level almost never does: multi-flue stacks, coal-to-gas conversion scars, lime mortar nearing 120 years old, and HPO review on anything visible from the street. Our crews know the difference between a parlor flue and a coal furnace flue before the camera even goes down.
Every Washington job gets a written price before work starts. Not an estimate you sign in the dark after a “free inspection.” A line-item scope, price, and warranty delivered in writing under Haven Standard Clause 1. Corrine Halstead runs our Washington operation, and she would rather lose a bid than submit one without photographic evidence attached. That’s why Clause 4 has been policy here since 2009: documented photo record on every visit, not as an add-on. Washington homeowners read the three-star reviews. We earn the five-star ones by showing you the cracked flue tile before we ask for a repair deposit.
Our Chimney Repair Services in Washington
Mortar Repointing
Repointing in Washington is not optional maintenance; it’s what holds 120-year-old brick stacks together. DC winters deliver 30 to 50 freeze-thaw cycles per season, and every one of them works the soft lime mortar joints in Capitol Hill and Petworth row houses a little looser. We cut out deteriorated joints and replace them with mortar matched to the original lime composition, not a harder Portland cement that would crack the soft antique brick it surrounds. Typical repointing for a single residential stack runs $350-$900 depending on how much of the stack has opened up.
Spalling Brick Repair
Spalling is what happens when DC’s summer humidity drives water into brick and winter freezes it from the inside. The brick face pops off. We see it most often on chimney shoulders and crown edges in Georgetown and Columbia Heights, where decades of moisture have done more damage than the original builders could have anticipated. We remove and replace compromised brick with period-appropriate material, matching color and texture so the repair doesn’t read like a patch. Spalling brick repair in Washington typically costs $800-$1,400. If we find nothing but surface flaking, we’ll tell you it can wait, and the photo report will show you why.
Chimney Waterproofing
Chimney waterproofing in Washington is bought too late in about half the jobs we see. Once you’ve repointed and rebuilt, a breathable siloxane waterproofing treatment slows the next decade of freeze-thaw damage. We use Gelco waterproofing products because they allow moisture vapor to escape while blocking liquid water, which matters in DC’s high-humidity summers. A typical waterproofing application on a DC row house stack runs $400-$750. We do not recommend waterproofing as a substitute for structural repair, and if someone else told you it is, get a second opinion. Ours is free when you bring a competitor’s written quote.
Flashing Repair
Where the chimney meets the roof is where DC row houses leak first. Flashing failure is the leading cause of chimney-related water damage we document in Washington, and it’s also the easiest repair to get wrong if you reuse old step flashing instead of cutting new pieces. We install new copper or aluminum flashing cut to the pitch of your specific roof, sealed, and photographed on completion. Flashing repair on a DC row house typically runs $450-$1,100. Water stains on the ceiling near the chimney are the usual tell, and by spring in Washington, unaddressed flashing failures have already soaked into plaster and joists.
Our full Chimney Repair team handles all of the above plus tuckpointing, crown replacement, and partial or full rebuilding. If your stack is beyond repointing, we’ll quote the rebuild with photos showing exactly why.

We install and work with components from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, sourced through Haven’s buying network to keep Duraflex service in Washington and all our customers’ material costs honest. When a Capitol Hill flue needs a new liner, we’re installing a DuraFlex or Olympia Chimney liner sized to the actual flue dimensions, not whatever is on the truck. Washington homeowners should never pay a markup for a brand name bolted onto a generic part. Every component we install has a written warranty and appears in the photo record you keep.
Common Chimney Repair Problems We See in Washington Homes
- Fires lit in the wrong flue. Post-coal-to-gas conversion row houses in Capitol Hill and Shaw often have two or three flues behind one brick face, and after decades without caps or labels, nobody alive remembers which one served the original fireplace. The result: fires lit in an old coal furnace flue with a cracked clay liner. This is the most avoidable fire hazard we document in Washington.
- Freeze-thaw spalling on century-old lime mortar. Washington’s 30-50 freeze-thaw cycles each winter crack soft lime mortar joints progressively, and summer humidity drives the water deeper. Deterioration between seasons is measurable here, which is why an annual camera look is a defensible maintenance practice, not a sales routine.
- HPO review on visible exterior work. In Georgetown, Capitol Hill, LeDroit Park, and other designated historic districts, any exterior chimney work visible from a public way may require Historic Preservation Office review and permits before work begins. We’ll flag it early and help you understand the process, but no reputable contractor should start without the paperwork.
- Uncapped abandoned flues left open for decades. A coal furnace flue that was never capped after conversion is an open pipe to the weather: rain, snowmelt, birds, squirrels, and in DC, raccoons. By the time you restore wood burning, that flue is often cracked, clogged, or lined with creosote from fires that should never have been lit there.

FAQs - Chimney Repair in Washington
The only honest way to know is to have the stack scoped with a camera and trace each flue from its firebox opening to the top of the stack. In many Capitol Hill and Shaw row houses, the original coal furnace flue and the fireplace flue sit side by side behind the same brick face, and after decades without caps or labels, the only way to distinguish them is by sending a camera down from the crown and identifying which one terminates at which opening. We do this on every Level 2 inspection and give you the footage. Do not light a fire and see what happens. A few hundred dollars for documentation beats a chimney fire. Call (240) 621-1264 for a free estimate.
If your chimney is visible from a public way and your home sits within a DC Historic Preservation Office-designated historic district, which includes most of Georgetown, yes, repointing or crown replacement may require HPO review and permits before work begins. The standard for what counts as visible from the street includes any portion of the chimney a person can see standing on the sidewalk or roadway. We’ll help you determine whether your specific project triggers review before we touch a brick. The paperwork is not optional, and skipping it can stop the job mid-scaffold. Call (240) 621-1264 and we’ll walk you through what your address requires.
Because Washington’s freeze-thaw cycle is doing the damage, not the fires. DC sees roughly 30 to 50 freeze-thaw cycles every winter, and every cycle forces water trapped in the soft lime mortar to expand and contract, breaking down the joints a little at a time. Add the District’s high summer humidity driving moisture deeper into century-old brick, and you get mortar that crumbles even if the fireplace sits cold all season. The fix is repointing with a compatible lime-based mortar, then a breathable waterproofing treatment. The photo record we give you after each visit shows exactly how much joint deterioration happened since the last inspection. Call (240) 621-1264 for a free estimate.
Usually not. The clay tile liners in century-old DC coal furnace flues were installed for lower-temperature, lower-creosote coal exhaust, and after decades of exposure to Washington’s wet climate and, in too many cases, improper wood fires, they are typically cracked, deteriorated, or sized wrong for a modern wood-burning fireplace. The camera often shows degraded tile with gaps that allow heat and gas to reach combustible framing. A properly sized stainless liner from DuraFlex or Olympia Chimney, installed in the correct flue, is the standard fix. Never assume the old clay liner is fine because the house hasn’t burned down yet. Call (240) 621-1264 and we’ll show you what the camera found.
Rain, snowmelt, and humidity are the first problems: an uncapped flue channels moisture directly into the interior stack, accelerating brick and mortar damage. Birds and squirrels are next, building nests that can completely block a flue. Raccoons are the worst, because they’ll use a warm chimney as a den in spring, and their droppings create a serious biohazard. The fix is a properly sized chimney cap with animal screening, installed after we camera-scan to check for active nests or structural damage. Plan on a few hundred dollars for the cap and installation in Washington. Call (240) 621-1264 for a free estimate.
What Actually Happens If You Skip It
On a Capitol Hill rowhouse from 1905, our tech scoped a three-flue stack after the owner reported smoke backing into the parlor. The camera revealed the homeowner had been using the old coal furnace flue, its clay tile liner cracked and coated with third-degree creosote, while the fireplace flue sat abandoned with a missing cap. We documented everything on screen, repointed the deteriorated mortar joints, installed a properly sized DuraFlex liner in the correct flue, and capped the unused openings so the owner could burn safely for the first time since the conversion. That is the DC story we see again and again. The homeowners had no idea. Now they have photos, a written scope, and a chimney that works.
