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.
Chimney Cleaning in Lexington, MA
Chimney cap and crown work in Lexington runs $180-$1,850 depending on whether we’re sealing hairline cracks or replacing a multi-flue cap on a center-chimney colonial. The town’s inland freeze-thaw cycles and two distinct housing eras - 18th-century colonials with massive multi-flue stacks and 1960s-70s ranches with aging clay tile - create crown and liner failures that coastal sweeps rarely see. Call (508) 850-0489 for a written estimate before any work starts.
Why Lexington Homes Are Different
Lexington sits 11 miles inland from Boston, which means colder overnight lows and sharper freeze-thaw cycling than coastal towns. That thermal stress attacks mortar joints at chimney crowns and spalls clay tile liners in the town’s sprawling mid-century neighborhoods.
The historic district around the Battle Green adds another layer. Those center-chimney colonials contain two to four offset flues within a single masonry mass, including sealed kitchen hearths a technician can easily miss. A sweep trained only on standard suburban construction might scope the wrong passage or overlook a deteriorating secondary flue. We’ve found active carbon monoxide risks in flues past owners assumed were fully abandoned.
Meanwhile, the postwar ranch and split-level developments covering most of Lexington carry original clay tile liners now 60-70 years old. Freeze-thaw has cracked them at the joints. The result: two chimney populations, two failure modes, one ZIP code.

Before
AfterChimney Cap & Crown in Lexington

Lexington’s freeze-thaw cycles destroy chimney crowns faster than coastal towns, and the town’s center-chimney colonials demand multi-flue caps that fit irregular masonry masses standard retail caps won’t cover. We install and service caps and crowns under the Haven Standard, with a written price before work starts and a photo record when it’s done. Chimney Cap & Crown
Cap Installation
Signs you need it
Water staining on the firebox ceiling, rusted damper hardware, or birds nesting in an uncapped flue.
What it costs in Lexington
Single-flue cap installation runs $180-$450; multi-flue caps for center-chimney colonials run $650-$1,200.
How we do it
We measure the flue or chimney mass, fabricate or source a cap from Olympia Chimney or Famco through our Haven buying network, and secure it with masonry anchors and a bead of high-temp sealant.
Crown Repair
Signs you need it
Visible cracks in the concrete crown, pieces of crown material in the yard, or water infiltration after thaw cycles.
What it costs in Lexington
Hairline crack sealing with crown coating runs $350-$650; partial crown rebuilds run $850-$1,500.
How we do it
We grind out cracked material, apply a bonding agent, and pour new high-strength concrete sloped to shed water, with a 1-inch overhang past the brick.
What Chimney Cap & Crown Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Single-flue cap installation | $180 - $450 |
| Multi-flue cap installation | $650 - $1,200 |
| Crown coating / sealing | $350 - $650 |
| Partial crown rebuild | $850 - $1,500 |
Can a cracked chimney crown wait until spring?
Water already moves through freeze-thaw cracks in Lexington’s climate, and each cycle widens the damage. We can seal hairline cracks for $350-$650 now, or rebuild later for $850-$1,500. Call (508) 850-0489 for a camera inspection and written price.
Do center-chimney colonials need special caps?
Yes - standard single-flue caps won’t cover the irregular masonry mass or multiple flue openings. We measure on-site and source custom multi-flue caps from Olympia Chimney or Famco.
Chimney Liner & Rebuild in Lexington

Lexington’s mid-century housing stock carries original clay tile liners now 60-70 years old, cracked by decades of inland freeze-thaw. Those liners vent gas appliances and wood fireplaces into the same masonry mass, and a breach can pull combustion gases into living space. We replace and reline under Haven Standard Clause 1 - written price, written scope, written warranty before any work starts. Chimney Liner & Rebuild
Stainless Steel Liner
Signs you need it
Cracked clay tile visible on camera scan, flaking tile pieces in the cleanout, or a water heater or boiler venting into a compromised flue.
What it costs in Lexington
Stainless steel liner installation runs $2,800-$4,500 for a standard fireplace flue, or $1,800-$3,200 for a furnace or water heater flue.
How we do it
We pull a camera to confirm the full flue condition, drop a continuous 316Ti stainless steel liner with proper insulation and top plate, and document the completed installation with photos.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or mortar joints eroded to finger-width gaps.
What it costs in Lexington
Partial rebuilds from the roofline up run $3,500-$6,500 depending on height and accessibility.
How we do it
We dismantle to sound masonry, rebuild with matching brick and type-N mortar, install a new concrete crown with proper overhang, and cap with a Gelco or Copperfield cap.
What Chimney Liner & Rebuild Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Stainless steel liner (fireplace) | $2,800 - $4,500 |
| Stainless steel liner (appliance) | $1,800 - $3,200 |
| Partial chimney rebuild | $3,500 - $6,500 |
| Full chimney rebuild | $8,500 - $15,000 |
How long does a stainless steel liner last?
Properly installed 316Ti stainless steel liners carry a lifetime warranty and typically outlast the appliances they vent. We document the installation with photos under Haven Standard Clause 4.
Can I just patch cracked clay tile instead of relining?
Individual tile replacement is rarely cost-effective and doesn’t address the systemic cracking freeze-thaw causes. A continuous stainless liner seals all breaches and carries a written warranty.
Brands We Service in Lexington
We source caps, liners, and rebuild materials through the Haven buying network from Gelco, Olympia Chimney, Famco, and Copperfield. Most standard parts are stocked for Lexington jobs, with specialty center-chimney caps fabricated to measure when needed.

What Lexington Customers Say
"They ran a camera down the flue and showed me the cracked tiles on a screen. The previous company had swept it twice and never mentioned it."
