Chimney, Masonry, and Stove Services in Tyngsborough, MA
On Duty Chimney, Masonry & Stove serves Tyngsborough from our Leominster base, and we are at home with the town’s mix of older riverside homes, lake neighborhoods, and newer suburban development. 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 Tyngsborough 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 Tyngsborough Chimneys Need Attention
Tyngsborough straddles the Merrimack River at the northern edge of Middlesex County, right against the New Hampshire line, and it has grown from an old riverside farming town into a suburban community while keeping a lot of its water-and-woods character. Its housing runs from antique colonials and riverside homes to the lake neighborhoods around Flint and Massapoag ponds and the newer subdivisions that filled in with commuter growth.
That range means a range of chimneys. The older river and center homes have brick masonry and clay liners that have aged for a century or more, while the newer neighborhoods have masonry chimneys built for single-family fireplaces and stoves. All of it weathers the same New England freeze and thaw that wears crowns and mortar over time.
Tyngsborough’s lake and river neighborhoods include a number of older cottages, some built for seasonal use and later converted to year-round homes. A chimney that was fine for occasional summer fires is not always 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.
As a growing suburban town with steady turnover, Tyngsborough has many chimneys that change hands without ever being inspected. Whether you have bought an older riverside home or a newer house near the line, a first camera inspection is the fastest way to know exactly what your chimney needs before winter.
Common Chimney Problems in Tyngsborough Homes
On Tyngsborough’s older river 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 fires but were never sized for full-time winter heating, and newer homes more often need a first inspection of an uninspected fireplace or stove flue.
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.
Tyngsborough sits on the Merrimack near the New Hampshire line, and we serve the towns around it, including Westford, Chelmsford, Dunstable, Groton, and Pepperell.
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 Tyngsborough chimney is overdue for inspection, sits on an older or converted lakeside home, or is showing worn mortar or a cracked crown, 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 Tyngsborough’s river, lake, and newer neighborhoods?
Yes. We work throughout Tyngsborough, from the older homes along the Merrimack to the lake neighborhoods and the newer subdivisions near the New Hampshire line. Our Leominster base keeps scheduling straightforward.
My Tyngsborough 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.
My Tyngsborough home is an older colonial. Can you repair the masonry?
Yes. Crown rebuilds, tuckpointing, and brick repair on the town’s older homes are core services. We inspect with a camera first, show you the damage, then quote the repair.
How often should a Tyngsborough 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.
