Chimney, Masonry, and Stove Services in Concord, MA
On Duty Chimney, Masonry & Stove serves Concord from our base in nearby Leominster, and we specialize in the careful, well-documented work the town’s historic homes require. Founded by Bryan LeBlanc, On Duty is built on nearly two decades of fire service experience with the Leominster and Ashburnham Fire Departments, which is why every job centers on fire prevention, safety, and code compliance.
Our crew of roughly 20 technicians brings a camera to every sweep and repair, so a Concord homeowner sees the true condition of each flue on a screen before any work begins. That documented, evidence-first approach is how we replace guesswork with a clear plan, and it is why so much of our work comes from repeat customers and referrals.
Why Concord Chimneys Need Attention
Few towns in America are as historic as Concord, from the Old North Bridge to the homes of Emerson, Hawthorne, and the Alcotts, and its housing reflects that. The Old Manse dates to 1770, Orchard House and The Wayside are museums today, and much of the town sits within one of six local historic districts overseen by a Historic Districts Commission. For homeowners, that means antique masonry chimneys and, in the districts, real rules about exterior work.
Concord’s antique homes were built around large masonry chimneys, often a central stack serving several flues, and after two centuries or more those crowns, mortar joints, and liners need knowledgeable attention. Many owners heat with wood, adding demand on old flues. This is preservation-grade work: the goal is to keep an original chimney serving the home safely, not to replace it.
In Concord’s historic districts, exterior chimney work can require review, so documentation matters even more than usual. Our camera inspections give you and the commission a clear, photographed record of what is failing and why, which supports a repair that is both safe and sympathetic to the home’s period.
Concord’s careful approach to preservation also rewards owners who keep good records, and our photo-documented inspections build exactly that kind of history for a home. Over time, a file of dated camera inspections shows how a chimney has been maintained, which is useful not only for safety and the historic districts but also when an antique Concord home eventually goes to market and a buyer wants proof the masonry has been cared for.
Common Chimney Problems in Concord Homes
On Concord’s antique homes, the recurring issues are deteriorated crowns and mortar, unlined or under-lined flues, and modern wood stoves connected to chimneys built for open hearths. Central chimneys serving multiple flues mean a single hidden defect can affect more than one fireplace.
Camera documentation is essential here. We diagnose from the inside to avoid disturbing historic masonry, show you precisely what needs attention, and recommend the least invasive, code-compliant fix, keeping the character of a Concord home intact.

How We Work, and the Area We Cover
Every job starts with a camera. A technician runs each flue, documents the crown, liner, and masonry with photos, and walks you through what we find in plain language, separating what needs attention now from what can safely wait.
Concord sits along Route 2 near the Concord and Assabet rivers, and we serve the towns around it, including Acton, Carlisle, Lincoln, Bedford, Maynard, and Sudbury.
What It Costs
Pricing depends on your chimney and the work involved, but to set expectations: a standard chimney cleaning runs $349 to $550 per flue, with $200 for each additional flue, and a camera inspection is included with that service at no extra charge.
A standalone Level 2 camera inspection, the kind often needed for a home sale or after a chimney fire, runs $200 to $500. Masonry and relining are quoted after the inspection, once we can show you exactly what the chimney needs.
If you own a historic home in Concord and the chimney is overdue for inspection, missing a liner, or showing worn mortar or a cracked crown, call On Duty at (978) 696-7933 or book online. We will document its condition and recommend a careful, period-appropriate fix.
Frequently Asked Questions about General Fireplace Repair
My Concord home is in a historic district. Can you handle work that needs commission review?
Yes, we are used to it. In Concord’s historic districts, exterior chimney work can require review by the Historic Districts Commission. Our photographed inspections document the condition and support the approval process, and we plan repairs that respect the home’s period.
Can you inspect an antique center chimney with several flues?
Yes. We camera each flue in a central chimney, document the crown and liner, and give you a flue-by-flue report so you know the condition of every fireplace it serves.
My Concord colonial has no chimney liner. Is that a problem?
It can be. Many antique homes were built without liners, which are now standard for safe venting. We camera the flue and assess whether it is safe as-is or would benefit from a code-compliant liner, always with preservation in mind.
I heat my Concord home with wood. How often should the chimney be swept?
At least once a year, and sometimes twice for heavy burners. Wood heat builds creosote faster than most homeowners expect, and an annual camera inspection is the best way to stay ahead of a chimney fire.
Are you licensed and insured in Massachusetts?
Yes. On Duty is fully licensed and insured in Massachusetts, Bryan LeBlanc holds a Massachusetts Construction Supervisor License and Home Improvement Contractor registration, and our technicians are trained to Massachusetts code.
What happens if you find a problem during the inspection?
We show you the issue right on the camera screen, explain what it means for safety and everyday use, and give you a photo-documented estimate. There is no obligation to have us do the work, and we always separate what needs attention now from what can safely wait, so you can make an informed decision.
