Chimney, Masonry, and Stove Services in Harvard, MA
On Duty Chimney, Masonry & Stove serves Harvard from our base in nearby Leominster, and we specialize in exactly the kind of antique and historic homes the town is known for. 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 Harvard 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 Harvard Chimneys Need Attention
Harvard is one of the best-preserved rural towns in the region, settled in the 1650s and full of colonial and Victorian homes clustered around its historic common, with winding, stone-walled roads leading out to working apple and peach orchards and the centuries-old village of Still River. It is antique-home country, and antique homes come with antique chimneys.
Many Harvard houses still rely on the large center chimney or the multiple masonry chimneys they were built with, sometimes two or three hundred years ago. Those chimneys are often structurally sound and beautiful, but their crowns, mortar, and liners have weathered centuries of New England freeze and thaw, and many Harvard homeowners heat with wood stoves that put real demand on an old flue. Preserving these chimneys takes a careful eye, not a one-size-fits-all approach.
Harvard homeowners tend to care deeply about the character of their properties, and rightly so in a town this historic. That shapes how we work here. The goal is almost never to rip out and replace, but to stabilize and preserve, keeping an original chimney serving the home safely for another generation rather than swapping it for something that does not belong on a house of its age.
Because Harvard homeowners tend to be committed to preserving their properties, we work alongside that goal rather than against it. Small, early interventions, resealing a crown, repointing a few feet of mortar, adding a discreet liner, tend to extend the life of an original chimney for decades and cost far less than the major rebuild that becomes necessary when an antique chimney is neglected. On a Harvard home, staying ahead of the wear is both the safer and the more economical path.
Common Chimney Problems in Harvard Homes
On Harvard’s antique homes, the recurring issues are deteriorated mortar and crowns, chimneys with no liner at all (common in very old construction), and flues that were never sized for the wood stove now connected to them. Some center chimneys serve several flues at once, so a single problem can affect more than one hearth.
This is exactly the kind of work where camera documentation earns its keep. Rather than opening up historic masonry to guess at a problem, we inspect from the inside, show you precisely what is going on, and recommend the least invasive fix that brings the chimney up to a safe, code-compliant standard.

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.
Harvard sits in the orchard country between Route 2 and Interstate 495, and we serve the towns around it, including Bolton, Littleton, Boxborough, Ayer, Devens, and Lancaster.
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 an older home in Harvard and the chimney has not been inspected in years, is missing a liner, or is 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 fix that respects the home.
Frequently Asked Questions about General Fireplace Repair
My Harvard home is a colonial with 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 an unlined chimney is safe as-is or would benefit from a code-compliant liner, always with an eye toward preserving the original masonry.
Can you work on a very old center-chimney farmhouse without damaging it?
Yes. Our camera-first process is designed to diagnose from the inside so we avoid unnecessary demolition of historic masonry. When repair is needed, we match materials and methods to the age of the home.
I heat my Harvard home with a wood stove. 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.
Do you handle masonry and crown rebuilds on antique chimneys?
Yes. Crown rebuilds, tuckpointing, and brick or stone repair on historic chimneys are core work. We inspect first, show you the damage on camera, then quote a repair matched to the home’s era.
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.
