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 Arlington
Most chimney repair in Arlington runs $450-$2,800 depending on whether you need mortar repointing, crown rebuilding, or full relining of an original clay tile flue. We’re Hearthstone Chimney Co., and our crews work Arlington daily from our Washington, DC office, dispatching to Ashton Heights, Westover, Lyon Village, and Dominion Hills with the parts and materials already on the truck. Call (571) 489-4365 and a live person will answer, 24 hours a day.
Arlington’s housing stock is unlike anywhere else in Northern Virginia. The 1940s wartime and postwar federal-workforce building boom filled neighborhoods like Ashton Heights and Westover with nearly identical brick cape cods and ramblers, many built fast for wartime workers with clay tile flues sized for coal furnaces, not the wood-burning fireplaces owners added decades later. That mismatch is the root of most serious chimney problems we see here. Our Chimney Repair team documents every flue with a Level 2 camera inspection, shows you the photos, and explains what you’re looking at before we recommend any work.
Why Hearthstone Chimney Co. Is Arlington’s Preferred Chimney Repair Company
We’ve served local communities for over 42 years, and Arlington has been central to our route since we started. The county’s geographic size means we’re rarely more than 20 minutes from any call, and our technicians know the difference between a Dominion Hills rambler with original coal flue and a newer Lyon Village townhouse with a prefab metal chase.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your chimney can safely wait a season, we’ll say so. If the clay tile is cracked and the flue is undersized for your wood stove, we’ll show you the camera footage and explain exactly why draft is failing.
Every job carries our 90-Day Done Right Promise in writing, no arguing. If it’s not right, we come back. Our technicians are background-checked and uniformed, most repairs finish in a single visit, and the price we quote is the price on the invoice. A square deal, no surprises on the bill.
Calls are answered by a live person, 24/7. Not a voicemail, not a callback queue. We’ve been doing it this way since 1984.
Our Chimney Repair Services in Arlington
Mortar Repointing & Tuckpointing
The soft lime mortar used in Arlington’s 1940s-era chimneys erodes faster than modern Portland cement mixes, especially after 15-25 freeze-thaw cycles each winter. In Westover and Ashton Heights, we routinely find crown joints and bed joints ground to powder while the bricks themselves are still sound. Tuckpointing removes the failed mortar to proper depth and packs new, color-matched refractory mortar that moves with the brick instead of cracking against it. We don’t grind out good mortar to pad the bill. We probe, photograph, and show you what’s actually failed.
Spalling Brick Repair
Spalling, where the brick face flakes off from water trapped behind it, is common on Arlington’s older chimneys that lack proper crowns or flashing. The humid subtropical summers here wick moisture into porous brick, and the first hard freeze pops the surface. We cut out spalled bricks, source matching replacements when possible, and rebuild with proper through-wall flashing so the problem doesn’t repeat next winter.
Chimney Waterproofing
Arlington’s combination of high summer humidity and hard winter freezes makes waterproofing essential for masonry chimneys, even if you never burn a fire. An unlined or poorly lined flue acts like a wick, drawing moisture down through the summer that accelerates interior tile cracking and mortar joint erosion. We apply vapor-permeable sealers from professional-grade suppliers that let the chimney breathe while blocking liquid water. A treated chimney sheds rain instead of absorbing it, which extends the life of mortar, brick, and any liner system you have.
Flashing Repair
Flashing is the sheet metal seal where your chimney passes through the roof, and it’s the most common leak point we find in Arlington’s older neighborhoods. The original step flashing on 1940s and 1950s homes was often galvanized steel that rusts through in 20-30 years, and many were installed without proper counterflashing reglets. We remove the old metal, inspect the decking and rafter tails for rot, and install new copper or stainless flashing with proper soldered seams and reglet joints. In Dominion Hills and Lyon Village, where roofs have been reshingled multiple times over original flashing, this repair stops the chronic ceiling stains that homeowners have learned to live with.
Chimney Rebuilding
When mortar joints are failed throughout, the crown is collapsed, and the flue liner is deteriorated, partial or full rebuilding becomes the honest recommendation. We don’t lead with this. We lead with the camera. But Arlington’s wartime housing stock is now 70-80 years old, and some chimneys have simply reached the end of their service life after decades of deferred maintenance. Our rebuilds use matching brick, proper reinforced concrete crowns with drip edges, and correctly sized flue liners from HeatShield or DuraFlex. The work is photographed at each stage, and we pull county permits when required.

Trusted Brands We Service in Arlington
We stock parts and materials from HeatShield, Gelco, Olympia Chimney, and Famco on our Arlington-area trucks, which means most repairs don’t wait on a warehouse order. HeatShield’s cerfractory flue resurfacing system lets us restore sound clay tile liners that have minor cracking without a full tear-out. Gelco and Olympia Chimney supply the caps, dampers, and chase covers we install on Arlington’s metal chase systems and prefab fireplaces. Famco’s roofline ventilation products solve the draft problems that plague postwar conversions with undersized flues. We don’t use builder-grade substitutes. The materials matter, and we choose ones that last.
Common Chimney Repair Problems We See in Arlington Homes
- Undersized clay tile flues from coal-furnace conversions. In Ashton Heights and Westover, the fireplace was often a postwar add-on to a chimney built for a coal furnace. The 6×6 or 7×7 clay tile is too small for modern wood-burning appliances, draft is chronically poor, and glazed creosote builds up faster than owners expect. Homeowners are regularly surprised to learn the “original” fireplace they bought the house for was never properly sized for wood use.
- Freeze-thaw damage to crowns and flaunching. Arlington’s 15-25 annual freeze-thaw cycles spall the soft 1940s lime mortar at chimney crowns faster than in drier inland Virginia markets. Once the crown cracks, water tracks down behind the flashing, rusts the firebox and damper assembly, and stains ceilings below.
- Summer humidity accelerating interior deterioration. High humidity wicks into unlined or poorly lined flues through June, July, and August. By the time owners light the first fall fire, interior tile cracking and mortar joint erosion have already compromised the flue. The damage happens invisibly, which is why we recommend camera inspection before burning season.
- Failed flashing on multiple-times-reshingled roofs. In neighborhoods where roofs have been replaced two or three times over 70 years, flashing is often layered, caulked, or simply ignored by roofers focused on speed. The result is chronic, low-grade leaking that rots roof decking and stains plaster before anyone notices the chimney itself.

FAQs - Chimney Repair in Arlington
You likely need relining if the original clay tile is 6×6 or 7×7, which is too small for any modern wood-burning appliance. We see this exact situation in Ashton Heights and Westover regularly. Our Level 2 camera inspection will measure the flue, check for cracked or missing tiles, and show you the footage. If the tile is sound but undersized, we typically recommend a stainless steel liner like DuraFlex 316L, properly insulated and sized to your appliance. If the tile is deteriorated, we may recommend HeatShield resurfacing for minor damage or full relining for more extensive failure. Nothing is recommended without camera evidence you can see yourself. Call (571) 489-4365 for a free inspection.
Arlington’s 15-25 annual freeze-thaw cycles aggressively spall the soft 1940s lime mortar in crown joints and erode flaunching faster than in drier inland Virginia markets. Water enters micro-cracks during the day, freezes overnight, and expands with enough force to pop mortar chunks loose. Once the crown is compromised, water tracks behind the flashing, rusts metal components, and rots adjacent roof decking. We inspect crowns and flashing as a standard part of every Arlington service call, and we repair with modern refractory materials designed to handle the cycle. Call (571) 489-4365 to schedule before the next hard freeze.
Yes. We will not recommend a chimney rebuild without showing you Level 2 camera footage of the damage and explaining what you’re seeing. Our inspection protocol is documented like an engineer and explained like a craftsman. You’ll see cracked flue tiles, deteriorated mortar joints, water intrusion patterns, or whatever condition actually exists. If the chimney can be saved with repointing, relining, or crown repair instead of rebuilding, we’ll tell you that plainly. The camera doesn’t lie, and we don’t guess. Call (571) 489-4365 to book an inspection.
Tuckpointing replaces failed mortar joints while leaving sound bricks in place. Full rebuilding removes and replaces damaged brick, rebuilds the crown, and often includes relining. For Arlington’s 70-80 year old chimneys, tuckpointing is appropriate when bricks are sound and damage is limited to mortar joints and minor crown cracking. Rebuilding becomes necessary when multiple courses are spalling, the crown has collapsed, the flue liner is failed throughout, or the structure has shifted. We determine which you need through camera inspection and physical probe, not from the ground with binoculars. Many Arlington chimneys fall between these two points, and we’ll show you exactly where yours stands. Call (571) 489-4365 for an honest assessment.
Yes. Waterproofing protects the masonry itself, not just the flue. Arlington’s high summer humidity wicks into porous brick and unlined or poorly lined chimneys even when no fire is lit. By fall, that moisture has accelerated interior tile cracking and mortar joint erosion. A vapor-permeable waterproofing treatment lets the chimney breathe while blocking liquid water, which extends the life of mortar, brick, and any future liner system. We’ve treated Dominion Hills chimneys that haven’t seen a fire in years, simply to stop the slow moisture damage that leads to expensive rebuilding later. The treatment pays for itself in deferred major repairs. Call (571) 489-4365 for a free evaluation.
