Chimney, Masonry, and Stove Services in Gardner, MA
On Duty Chimney, Masonry & Stove serves Gardner from our nearby Leominster base, and we know the housing an old manufacturing city leaves behind: older, closely built, and often multi-family. 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 Gardner 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 Gardner Chimneys Need Attention
Gardner earned its nickname, the Chair City, from a furniture-making industry that made it one of the country’s great centers of chair and furniture manufacturing. That industry drew generations of workers who filled dense neighborhoods of older homes near the factories, and it left the city with a stock of nineteenth and early twentieth-century houses, many of them multi-family, built close together.
That older housing was built around masonry chimneys, often tall brick stacks that have carried heat for well over a century. Gardner sits at higher elevation with long, cold winters, so wood and pellet heat are common, and steady winter burning puts real demand on an old flue. Between the age of the brick and the region’s freeze and thaw, crowns, mortar, and liners are the parts that wear.
A good share of Gardner’s older housing near the downtown and the factory districts is multi-family, and on those buildings a single chimney can vent more than one unit. Our camera-first process documents each flue separately, so an owner knows the condition of the venting for every apartment, not just the building as a whole. For landlords, that photographed record is often exactly what is needed to show the venting is safe.
Because so much of Gardner’s core was built close together and around the same era, a lot of its chimneys share a similar age and are reaching the same point of wear at once. A camera inspection is the quickest way to know whether an older chimney is due for masonry work or a new liner before winter.
Common Chimney Problems in Gardner Homes
On Gardner’s older worker housing and center-city homes, we regularly find worn crowns, open mortar joints, and aging or shared liners on tall multi-unit chimneys, along with wood and pellet stoves tied into masonry chimneys that were never sized for them. Because so many homes lean on wood and pellet heat through long winters, creosote buildup is a recurring safety concern.
A camera inspection is the right tool here. On a multi-unit chimney we document each flue separately; on a single-family home we give a clear read on the fireplace or stove venting, so you know what is safe and what needs work.

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.
Gardner sits in northern Worcester County near Route 2, and from the same trucks we serve the surrounding towns, including Westminster, Templeton, Winchendon, Hubbardston, Ashburnham, and Fitchburg.
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 Gardner home has an older chimney that has not been inspected in years, burns wood or pellets through the winter, or is showing worn mortar or a cracked crown, call On Duty at (978) 696-7933 or book online. We will document its condition and keep it safe.
Frequently Asked Questions about General Fireplace Repair
Do you work on Gardner’s older multi-family homes near the factory districts?
Yes. Tall masonry chimneys serving more than one unit are some of the most frequent work we do. We camera each flue separately and document its condition, which is often what owners and landlords need.
I burn pellets most of the winter in Gardner. How often should my chimney be serviced?
For a home that burns pellets or wood regularly, at least once a year before heating season. Steady winter burning builds creosote faster than most owners expect, and an annual camera inspection is the best way to catch a problem early.
My Gardner chimney has no liner. Should it have one?
Possibly. Many older homes were built without liners, which are now standard for safe venting, and a stove tied into an older chimney often needs a correctly sized liner. We camera the flue and recommend a liner only if it is actually needed.
Do you handle masonry and crown rebuilds on older Gardner homes?
Yes. Crown rebuilds, tuckpointing, and brick repair on the city’s older homes are core work. We inspect with a camera first, show you the damage, then quote the repair.
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.
