Chimney, Masonry, and Stove Services in Groton, MA
On Duty Chimney, Masonry & Stove serves Groton from our base to the south in Leominster, and we work regularly on exactly the kind of historic New England homes the town is full of. 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 Groton 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 Groton Chimneys Need Attention
Groton is a quintessential New England town, settled in 1655 and centered on a Main Street lined with Federal-period residences, with Greek Revival, Victorian, and colonial homes scattered among conservation land, farmland, and the Nashua and Squannacook rivers. It is a town of historic and antique homes, many of them heated at least partly with wood, and that combination defines the chimney work here.
Antique Groton homes were built around masonry, often a large center chimney or several flues serving multiple hearths. After a century or two of New England weather, those chimneys tend to need attention at the crown, in the mortar, and in the liner, and the wood stoves common in a rural town like Groton add their own demands. Careful, well-documented work matters more here than a quick patch.
Groton’s housing also includes a number of larger estate and farmhouse properties, some with multiple fireplaces and more than one chimney. On homes like these, keeping every flue on a documented inspection schedule prevents the common situation where a rarely used fireplace or a secondary chimney is overlooked until it becomes the source of a draft or a safety problem.
Groton’s larger and older homes have usually seen additions and updates over the generations, and a chimney may have been altered, capped, or partially rebuilt somewhere along the way, changes that are not always visible from the ground. A camera inspection is the reliable way to understand what has been done to a Groton chimney over its life and whether every flue still vents safely, which matters most on homes with more than one fireplace.
Common Chimney Problems in Groton Homes
In Groton’s older housing, the pattern is familiar: cracked crowns, eroded mortar, unlined or under-lined flues, and wood-stove connections into chimneys that were never sized for them. Multi-flue center chimneys mean a single hidden defect can affect more than one fireplace or appliance.
Camera documentation is how we handle historic homes responsibly. We diagnose from the inside, avoid tearing into sound masonry, and give you 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.
Groton sits along the Nashua River in the northwest corner of our service area, and we cover the towns around it, including Pepperell, Dunstable, Ayer, Littleton, Westford, and Shirley.
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 Groton 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
Do you serve Groton's town center and outlying areas?
Yes. We work throughout Groton, from the Federal-period homes along Main Street to the antique houses set on wooded and riverside roads. Our nearby Leominster base keeps scheduling straightforward.
My Groton home is an antique colonial with a big center chimney. Can you inspect all the flues?
Yes. We camera each flue in a multi-flue center chimney, document the crown and liner, and give you a flue-by-flue report so you know the condition of every fireplace or appliance it serves.
I heat with wood in Groton. How often should the chimney be swept?
At least once a year, more for heavy burners. Wood heat builds creosote quickly, and an annual camera inspection is the most reliable way to catch a problem before it becomes a chimney fire.
Can you repair historic masonry without damaging the home?
Yes. Our camera-first process diagnoses from the inside to avoid unnecessary demolition, and when repair is needed we match materials and methods to the age of the home.
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.
