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 Lexington
Chimney repair in Lexington typically runs $850-$3,200 depending on whether you need mortar repointing, spalling brick repair, or a partial rebuild, and most jobs are completed in a single visit with no-hassle upfront pricing agreed before we start. If your chimney is showing cracks, leaning, or water stains on the ceiling near the fireplace, it’s time to have it looked at. Lexington’s older masonry stacks don’t fix themselves, and the freeze-thaw cycles at this elevation make small problems grow fast.

Our Chimney Repair Services in Lexington
Mortar Repointing
Lexington’s historic brick chimneys were built with lime mortar, not the Portland cement mix used after 1900. Lime mortar breathes and flexes, which is why these chimneys have survived 150 years. But at roughly 1,000 feet in the Allegheny foothills, Lexington sees more freeze-thaw cycles than the Virginia Piedmont below. Water gets into those lime joints, freezes, expands, and grinds the mortar to powder. Repointing is not a one-time fix here. It’s maintenance.
We grind out the failed joints to proper depth and repoint with matching lime-based mortar or compatible modern blends that respect the original masonry. A typical mortar repointing job on a Lexington chimney runs $850-$1,800, depending on how many courses need work and whether scaffolding is required for height access.
Spalling Brick Repair
When mortar fails, water reaches the brick faces. Freeze-thaw pops the surface off in flakes - spalling. We see this constantly on Lexington’s older chimneys, especially on the south and west exposures that take the worst weather. Spalled bricks compromise the structural shell and open direct paths for water into your home.
We remove and replace spalled bricks with matching reclaimed or reproduction brick where possible, then repoint the surrounding joints. For a Lexington chimney with moderate spalling on one face, expect $1,200-$2,400. If the damage has penetrated multiple courses or the flue liner is exposed, we’ll show you exactly what the camera found before quoting any additional work.
Chimney Waterproofing
Lexington’s surrounding hardwood forestland means many residents burn wood as primary or serious supplemental heat - well above the Virginia average. That sustained burning season, combined with rain and snow on aged masonry, makes waterproofing a sound investment. We apply professional-grade breathable sealers that let moisture escape from inside the brick while blocking water entry from outside. A standard waterproofing treatment for a Lexington chimney runs $450-$950 depending on square footage and access.
Flashing Repair
The intersection where your chimney meets the roof is the most common leak point we find in Lexington homes, especially on the older pitched roofs in the historic district. Step flashing corrodes, counter-flashing separates, and the sealant dries to crumbs. We repair or replace flashing with galvanized steel, copper, or aluminum matched to your roof, and we seal with high-temperature compounds that flex with seasonal expansion. Most flashing repairs in Lexington run $350-$850.
Chimney Rebuilding & Tuckpointing
When spalling, mortar failure, or structural movement has compromised too much of the stack, partial or full rebuilding is the only safe option. We dismantle only what’s necessary, salvage reusable brick, and rebuild to current code with proper liners and caps. A partial rebuild of a Lexington chimney typically runs $2,200-$4,500; full rebuilds on larger multi-flue stacks can reach $6,000-$10,000. We never recommend rebuilding without camera documentation showing you exactly why it’s necessary.

Trusted Brands We Service in Lexington
We don’t use builder-grade substitutes. Our Chimney Repair crews in Lexington carry professional-grade materials from DuraFlex, HeatShield, and Copperfield - the brands that other sweeps call when they need something that lasts. DuraFlex stainless-steel liners handle the thermal stress of modern appliances venting into old flues. HeatShield cerfractory resurfacing restores cracked clay-tile liners without full replacement when the damage is contained. Copperfield caps, dampers, and flashing components stand up to Lexington’s wet winters and summer storms. We stock common sizes and fittings locally, so most Lexington repairs don’t wait on parts.
Common Chimney Repair Problems We See in Lexington Homes
- Lime-mortar joints crumbling from freeze-thaw cycles. At Lexington’s ~1,000-foot elevation, winter temperatures swing above and below freezing more often than in the Piedmont below. Water enters porous lime mortar, freezes, and expands. After enough cycles, the joint is gone and the brick above loses support. We repoint these joints with compatible materials that match the original breathability.
- Original unlined or clay-tile flues cracked by modern heat loads. Many Lexington chimneys were built for open fireplaces, not the airtight wood stoves or inserts homeowners added decades later. The concentrated heat exceeds what old clay tile or bare brick can handle. Cracks let creosote and combustion gases reach combustible framing. Our camera inspection finds these cracks before they become a house fire.
- Bricked-off second flues packed with hidden debris and creosote. Lexington’s 19th-century homes commonly have chimneys with two or more separate flue passages. One stays active for the fireplace. The other got partially bricked off when a coal or wood stove was removed - and sits packed with decades of accumulated creosote the homeowner has no idea exists. We find these with our camera. We clear them. We show you the photos.
- Water intrusion from failed crowns, caps, or flashing. Lexington sees steady precipitation year-round. A cracked crown or missing cap funnels water straight into the stack. In winter, that water freezes and accelerates everything else. We repair crowns with poured concrete or crown coat, install Gelco or Copperfield caps, and seal flashing with materials rated for the temperature swings this elevation produces.

FAQs - Chimney Repair in Lexington
Yes, you should have it inspected with a camera. That bricked-off flue is often packed with decades of creosote, debris, and sometimes bird nests that create a hidden fire risk and can block draft in your active flue. We were called to a brick Victorian on West Washington Street where the homeowner kept smelling creosote in the upstairs bedroom even with the damper closed. A Level 2 inspection with our camera showed the active fireplace flue was fine, but the second flue - bricked off years ago when a coal stove was removed - was packed with decades of debris and third-degree creosote the homeowner never knew existed. We cleared that abandoned flue, repointed the spalling lime-mortar joints on the exterior stack, and installed a DuraFlex stainless-steel liner in the active flue so the draft pulled correctly again. Call (540) 328-6986 to schedule a camera inspection - estimates are free.
Three reasons: lime mortar, elevation, and age. Your chimney was built with lime mortar, which is softer and more breathable than modern Portland cement - that’s why it survived 150 years, but it’s also why it erodes faster under freeze-thaw stress. Lexington sits at roughly 1,000 feet in the Allegheny foothills, which means more freeze-thaw cycles than the Virginia Piedmont below. Water enters, freezes, expands, and grinds the mortar away. Repointing every 20-30 years is normal maintenance for historic masonry at this elevation, not a sign of poor construction. Call (540) 328-6986 and we’ll show you exactly which joints need attention now and which can wait.
Demand camera evidence you can see for yourself. At Hearthstone, no liner is recommended without a Level 2 inspection that produces photos of the flue interior and a plain-English verdict explaining what the image shows. Original unlined brick flues or aged clay-tile liners in Lexington’s historic homes often crack under modern heat loads they were never designed for - that’s real, and it’s dangerous. But hairline surface cracks that don’t penetrate the wall are different from through-cracks that reach combustible framing. We show you the difference. We explain it. Then you decide. If another sweep quoted you a liner, bring us the estimate for a free second opinion. Call (540) 328-6986.
Third-degree creosote is thick, tar-like, and often glossy or hardened into a crust that drips or runs down the flue wall - it’s not the light, flaky soot you can brush off. It’s a concentrated fuel source that ignites at lower temperatures and burns intensely. In Lexington’s older multi-flue chimneys, it’s a bigger concern because the abandoned flues from removed stoves or coal appliances often have no airflow, so creosote condenses and accumulates for decades without ever drying or breaking down. Meanwhile, the active flue may be drafting poorly because the blocked flue disrupts pressure balance in the stack. Our camera finds this. We show you. Then we clear it safely. Call (540) 328-6986 for an inspection.
Yes. NFPA 211 recommends annual inspection regardless of use frequency, and in Lexington’s historic housing stock there’s an additional reason: your chimney may have been modified, damaged, or inhabited by animals since last season, and you won’t know until you look. A few fires in a cracked, blocked, or improperly vented chimney can do more harm than many fires in a sound system. Our $89 Seasonal Tune-Up includes a Level 1 inspection and basic cleaning. If we find something that needs repair, we’ll show you the camera evidence and explain your options, including which work can safely wait. Call (540) 328-6986 to schedule.
