Chimney, Masonry, and Stove Services in Lunenburg, MA
On Duty Chimney, Masonry & Stove serves Lunenburg from our base just minutes away in Leominster, and we know the town’s blend of antique colonials, lake homes, and newer neighborhoods well. 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 Lunenburg 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 Lunenburg Chimneys Need Attention
Lunenburg sits right next to Leominster and Fitchburg, and its housing runs from a historic center of one-acre lots filled with early-1900s Colonial Revivals and Queen Anne homes to genuine antiques like the 1748 saltbox and 1760 colonials that dot the town. Around Lake Whalom, once home to a beloved amusement park, older lake cottages mix with newer construction.
That range means a wide range of chimneys. The antique colonials and center homes have older brick masonry and clay liners that have aged for a century or more, while lake cottages and newer neighborhoods bring masonry chimneys built for fireplaces and stoves. All of it takes the same freeze-thaw wear on crowns and mortar.
Because Lunenburg is so close to our Leominster base, it is one of the towns we can reach fastest, which matters when a chimney problem is urgent: a sudden draft issue, a stovepipe failure, or a chimney that needs to pass a real estate inspection on a tight timeline.
The older lake cottages around Whalom are worth a special mention. Some were built for occasional summer use and were never sized or lined for full-time winter heating, so when a cottage becomes a year-round home, a camera inspection is the right first step to confirm the chimney suits how the house is now used.
Common Chimney Problems in Lunenburg Homes
On Lunenburg’s antique and center homes, we regularly find cracked crowns, worn mortar, and clay liners near the end of their service life. Converted lake cottages sometimes have chimneys that were fine for occasional summer fires but were never sized for full-time winter heating.
A camera inspection sorts it out. 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.
Lunenburg borders Leominster and Fitchburg, and we serve the towns around it, including Leominster, Fitchburg, Shirley, Townsend, 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 your Lunenburg chimney is overdue for inspection, sits on an older or lakeside home, or is showing worn mortar or a cracked crown, call On Duty at (978) 696-7933 or book online. We are minutes away and will document exactly what it needs.
Frequently Asked Questions about General Fireplace Repair
Do you serve the Lunenburg town center and the Lake Whalom area?
Yes. We work throughout Lunenburg, from the antique colonials near the center to the lake homes around Whalom and the newer neighborhoods. Since Lunenburg borders Leominster, it is one of the towns we reach fastest.
My Lunenburg home is a converted lake cottage. Is its chimney safe for year-round heating?
It is worth checking. Chimneys built for occasional summer fires are sometimes undersized or lightly built for full-time winter use. We camera the flue and tell you whether it suits how you actually heat the home.
Can you repair masonry on an older Lunenburg colonial?
Yes. Crown rebuilds, tuckpointing, and brick repair on the town’s antique and center homes are core services. We inspect with a camera first, show you the damage, then quote the work.
How often should a Lunenburg 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 and liner 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.
