Chimney, Masonry, and Stove Services in Sterling, MA
On Duty Chimney, Masonry & Stove serves Sterling from our base just minutes away in Leominster, and we work often on exactly the kind of historic and rural 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 Sterling 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 Sterling Chimneys Need Attention
Sterling is a historic farming town best known as the home of Mary Sawyer, whose pet lamb inspired the nursery rhyme, and it still keeps its rural character in the orchards, farms, and antique homes spread across the countryside near Wachusett. Its housing runs from colonial and farmhouse homes around the common and along the country roads to newer homes that filled in as the town grew.
Homes this old are built around masonry chimneys, often a large center chimney serving several flues, and after a century or two of New England weather the crowns, mortar, and liners are the parts that need attention. Sterling is rural, many homes burn wood, and being right next to our Leominster base, it is a town we can reach quickly when a chimney needs a look.
Sterling’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, since a neglected secondary chimney carries the same fire risk as the primary one.
Because Sterling is so close to our base, it is also one of the towns where we can respond quickly when something is urgent, a sudden draft problem, a stovepipe issue, or a chimney that failed a real estate inspection on a tight closing timeline. For antique homes especially, having a nearby company that already knows the town’s older masonry can be the difference between a quick fix and a stalled sale.
Common Chimney Problems in Sterling Homes
On Sterling’s colonial and farmhouse homes, we regularly find worn crowns, open mortar joints, and old or missing liners, along with wood stoves tied into masonry chimneys never sized for them. Because many homes lean on wood heat through the winter, creosote buildup is a recurring safety concern.
A camera inspection is the right tool for older rural homes. It lets us assess a chimney without tearing into it, show you the actual condition of each flue, and prioritize the work that keeps the home safe while respecting its original masonry.
Services We Provide in Sterling

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.
Sterling sits just west of Leominster near the Wachusett Reservoir, and we serve the towns around it, including Leominster, Lancaster, Clinton, West Boylston, Holden, and Princeton.
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 Sterling home has an older chimney that 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 are minutes away and will document exactly what it needs.
Frequently Asked Questions about General Fireplace Repair
Do you serve all of Sterling?
Yes, and since Sterling is minutes from our Leominster base, it is one of the towns we can reach fastest. We work throughout the town, from the antique homes around the common to the orchards and farmhouses along the country roads.
My Sterling home is an antique colonial with a big 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.
I heat with wood in Sterling. 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 also inspect a barn or workshop chimney on my Sterling 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.
