Chimney, Masonry, and Stove Services in Chelmsford, MA
On Duty Chimney, Masonry & Stove serves Chelmsford from our Leominster base, and we are equally comfortable with the town’s Victorian center homes and its newer suburban neighborhoods. 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 Chelmsford 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 Chelmsford Chimneys Need Attention
Chelmsford was founded in 1653 and grew into a town of distinct villages, Chelmsford Center, North, South, West, and East Chelmsford, and the Westlands, with North Chelmsford developing as its own industrial village near Lowell. Its housing runs from Victorian-era homes built between the late 1800s and the 1920s, many of them colonial-inspired with gabled roofs and dormers, through 1970s Colonial Revivals and ranches, to brand-new condominiums.
That wide range of ages means a wide range of chimneys. The Victorian and early-twentieth-century homes around Chelmsford Center have older brick masonry and clay liners that have aged for a century, while the postwar and newer neighborhoods have masonry chimneys built for fireplaces and stoves. All of it weathers the same freeze-thaw that wears crowns and mortar over time.
As a larger town near Lowell with steady housing turnover, Chelmsford has a lot of chimneys that change hands without ever being inspected. Whether you have bought a Victorian near the center or a newer home in the Westlands, a first camera inspection is the fastest way to know exactly what your chimney needs.
Chelmsford’s size and steady turnover also mean we see a wide range of prior work, some done well and some not. A previous owner’s quick patch, an undersized liner, or a cap that never fit right can all leave a Chelmsford chimney looking fine while hiding a real issue. A camera inspection gives you an honest, independent read on whatever was done before, so you know exactly what you are starting with.
Common Chimney Problems in Chelmsford Homes
On Chelmsford’s Victorian and early-twentieth-century homes, we regularly find cracked crowns, worn mortar, and clay liners near the end of their service life. In the postwar and newer neighborhoods, the more common issue is an uninspected fireplace flue or a wood or pellet stove added without a proper liner.
A camera inspection handles both. We document the crown, liner, and masonry with photos and give you a clear read on the venting, so you know what is safe and what needs work regardless of the home’s age.

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.
Chelmsford sits near Lowell along Routes 3 and 495, and we serve the towns around it, including Westford, Tyngsborough, Carlisle, Billerica, and Littleton.
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 your Chelmsford chimney is overdue for a sweep, has never been camera-inspected, or is showing cracked mortar, a weak draft, or a stained ceiling, call On Duty at (978) 696-7933 or book online. We will document exactly what it needs.
Frequently Asked Questions about General Fireplace Repair
Do you serve all of Chelmsford's villages, including North Chelmsford?
Yes. We work throughout Chelmsford, from Chelmsford Center to North, South, West, and East Chelmsford and the Westlands. Our Leominster base keeps scheduling straightforward.
My Chelmsford home is an older Victorian. Can you repair the masonry?
Yes. Crown rebuilds, tuckpointing, and brick repair on the town’s older center homes are core work. We inspect with a camera first, show you the damage, then quote the repair.
I just bought a newer Chelmsford home. Do I still need a chimney inspection?
If the fireplace or stove flue has not been inspected in a year or more, yes. Newer masonry chimneys still develop crown and liner issues, and a camera inspection is a quick way to confirm everything is safe.
How often should a Chelmsford chimney be swept?
For homes burning wood or pellets, once a year before heating season. An annual camera inspection is the best way to catch crown, liner, and creosote issues early.
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.
