We’ve been working on Lexington Fireplace Services since 1984. That means we’ve crawled into the flues of 1690s colonials near the Battle Green and inspected thousands of post-war capes in the eastern neighborhoods off Marrett Road. The problems are different in each. We know what to look for because we’ve seen it before.

Why Hearthstone Chimney Co. Is Lexington’s Preferred Chimney Liner & Rebuild Company

Lexington homeowners tend to stay put. The median home age here is among the oldest in Middlesex County, and the people who own them have owned them for decades. They remember the contractor who never called back. They remember the estimate that ballooned. We don’t work that way.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your clay flue tiles are cracked but the mortar is sound, we’ll say so. If the liner has failed and exhaust is leaking into the masonry, we’ll show you the image and explain exactly what needs to happen.

Every job carries our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to file, no argument. We’ve been in business for over 42 years because we plan to be here in thirty more, and that changes how you treat people.

Calls are answered by a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A real person who can dispatch a background-checked, uniformed technician to your Lexington home, usually the same day or next.

Our Chimney Liner & Rebuild Services in Lexington

Stainless Steel Liner Installation

Stainless steel is the standard for relining most masonry chimneys in Lexington, and for good reason. It handles the temperature swings of wood-burning and gas appliances, and it outlasts the clay flue tiles it replaces. We install DuraFlex and Olympia Chimney stainless liners with precise measurements taken on-site - no guesswork, no “close enough.” In the older homes near Hancock Street, where chimney dimensions weren’t standardized in the 1700s, custom fitting is essential. A liner that’s too small chokes the draft; one that’s too large allows creosote to accumulate in the gap. We get it right the first time.

Flexible Liner Installation

Some Lexington chimneys have offsets, bends, or transitions that rigid stainless can’t navigate. The colonial-era central stacks near the Battle Green are notorious for this - built to serve multiple fireplaces from a single exterior chase, they twist and narrow in ways no modern blueprint would allow. Flexible liners from DuraFlex thread through these irregular passages without damaging historic masonry. We’ve installed flexible liners in homes where other companies said a full rebuild was the only option. Sometimes it is. Sometimes it isn’t. We’ll show you the camera footage and tell you straight.

Liner Replacement

Clay flue tiles crack. It’s what they do after sixty years of Lexington freeze-thaw cycles, especially in the shaded lots along Waltham Street and the older streets near the town center where mature oaks keep chimneys damp well into winter. Once a tile cracks, exhaust gases seep into the brickwork. Carbon monoxide risk rises. Masonry deteriorates faster. We extract the failed liner, inspect the surrounding structure with our camera system, and install a new stainless or flexible liner sized exactly to your appliance. Most liner replacements in Lexington are completed in a single visit.

Partial Chimney Rebuild

When the liner has failed and the surrounding masonry is compromised, a partial rebuild is the square deal. We see this most often in the 1950s-1960s capes and colonials of eastern Lexington, ZIP code 02421, where original chimneys are hitting 60-70 years of age. The freeze-thaw damage has spalled the brick faces. The mortar joints have turned to sand. The crown has cracked and funneled water inside. We rebuild from the roofline up - new brick, our Chimney Cap & Crown in Lexington, new liner, new cap - backed by our 90-Day Done Right Promise. Photos before, photos after, and a written warranty you can hold in your hand.

Trusted Brands We Service in Lexington

We don’t use builder-grade substitutes. For liners, we specify DuraFlex and Olympia Chimney stainless and flexible systems - both carry the UL listings and warranty terms that matter when you’re installing inside someone’s home. For refractory repairs and resurfacing, we use HeatShield, a ceramic resurfacing system that restores deteriorated smoke chambers without a full tear-out. For caps, dampers, and termination hardware, we stock Copperfield and Famco components in our service vehicles, which means faster turnaround for Lexington customers and no waiting on a parts order from out of state. Every material is chosen for the specific conditions of your chimney, not for our convenience.

Common Chimney Liner & Rebuild Problems We See in Lexington Homes

• Freeze-thaw spalling in 60-year-old clay flue tiles. Eastern Massachusetts crosses the freezing point dozens of times each winter, and Lexington’s mature tree canopy keeps chimneys shaded and moisture-laden longer than in more open towns like Burlington. The result is accelerated spalling - the face of the tile flakes off, exposing the rough interior to creosote buildup and reducing draft efficiency.
• Multi-flue central stacks misidentified in pre-Revolutionary homes. On the oldest streets near Hancock Street and the Battle Green, a single exterior chase often served a parlor fireplace, a bedroom fireplace, and a former cooking hearth. These shared smoke chambers were never designed for modern gas inserts or wood stoves. We’ve found cases where a previous contractor lined the wrong flue, creating a genuine carbon monoxide hazard. Our camera inspection maps every flue before we touch anything.
• Crown cracks funneling water into post-WWII masonry. The capes and colonials of eastern Lexington, ZIP code 02421, were built with poured concrete crowns that have now endured 60-70 years of thermal cycling. Hairline cracks become channels. Water reaches the liner, accelerates deterioration, and in severe cases undermines the structural integrity of the stack. We replace crowns with proper overhang and drip edges, or install Gelco stainless caps for permanent protection.
• Deteriorated smoke chambers in homes that have never been relined. The parged surface of the smoke chamber - the area above the fireplace and below the flue - often erodes to bare brick in older Lexington homes. This creates turbulence, reduces draft, and increases creosote accumulation. HeatShield ceramic resurfacing restores the smooth, tapered profile the chimney was meant to have, without the cost and disruption of a full rebuild.
