Chimney, Masonry, and Stove Services in Stow, MA
On Duty Chimney, Masonry & Stove serves Stow from our Leominster base, and we work regularly on exactly the kind of antique and orchard-country 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 Stow 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 Stow Chimneys Need Attention
Stow is a historic Assabet Valley town that has kept its rural, orchard-country character, well known for its apple orchards and farms and for a landscape of conservation land, colonial homes, and winding country roads. Its housing runs from antique colonials and center-chimney farmhouses to the newer homes that filled in as Stow became a quiet residential town.
Homes this old were built around masonry, often a large center chimney serving several flues, and after two centuries or more those crowns, mortar joints, and liners need knowledgeable attention. Many Stow owners heat with wood, which adds real demand on an old flue, and the town’s owners tend to care about preserving the character of their historic homes.
Stow’s orchard and farm properties often include barns, workshops, and other outbuildings with their own chimneys or stove pipes, and these are easy to overlook when only the main house gets attention. If you heat a workshop or a converted outbuilding, those flues deserve the same camera inspection as the house.
On Stow’s antique homes, 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. Our camera-first process lets us diagnose these old chimneys from the inside and recommend the least invasive, code-compliant fix.
Common Chimney Problems in Stow Homes
On Stow’s antique colonials and farmhouses, 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 how we handle historic homes responsibly. We diagnose from the inside, avoid disturbing sound masonry, and give a clear, flue-by-flue picture so repairs are targeted and the character of the home is preserved.

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.
Stow sits in the Assabet Valley along Route 117, and we serve the towns around it, including Maynard, Hudson, Bolton, Boxborough, Sudbury, and Marlborough.
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 antique or orchard-country home in Stow 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 fix.
Frequently Asked Questions about General Fireplace Repair
My Stow home is an antique colonial with a large center chimney. Can you inspect all the 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.
Can you work on a historic Stow farmhouse without damaging it?
Yes. Our camera-first process diagnoses from the inside to avoid unnecessary demolition of historic masonry, and when repair is needed we match materials and methods to the age of the home.
I heat with wood in Stow. How often should the chimney be swept?
At least once a year, and sometimes twice for heavy burners. An annual camera inspection is the best way to stay ahead of a chimney fire.
Can you also inspect a barn or workshop chimney on my Stow property?
Yes. Outbuilding and workshop flues carry the same fire risk as the house, and we camera and document them the same way. It is worth including them in a yearly inspection.
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.
