Chimney, Masonry, and Stove Services in Marlborough, MA
On Duty Chimney, Masonry & Stove serves Marlborough from our Leominster base, and we know both sides of the city’s housing, the older downtown multifamily stock and the 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 Marlborough 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 Marlborough Chimneys Need Attention
Marlborough built its identity on shoemaking. In the nineteenth century it was one of New England’s shoe-manufacturing capitals, and waves of Irish, French-Canadian, and Italian immigrants filled dense new neighborhoods near the factories, especially the multi-apartment worker’s housing on French Hill west of downtown. That older, tightly built housing sits alongside the suburban development that came later as Marlborough grew into a small city on the Route 20 and Interstate 495 corridor.
The result is a real split in chimney needs. The downtown and French Hill multifamily stock has tall masonry chimneys, often serving more than one unit, that have weathered well over a century, while the newer parts of the city have masonry chimneys built for single-family fireplaces and stoves. Both see the same New England freeze-thaw, but the older, multi-unit chimneys tend to hide the most surprises.
Marlborough’s growth along the technology corridor brought newer housing and a steady turnover of owners and tenants, which means many of the city’s chimneys change hands without ever being inspected. Whether you have just bought an older downtown multifamily or a newer home off Route 20, a first camera inspection is the fastest way to know exactly what you have.
Marlborough’s mix also means we see a lot of homes that were converted over the years, a former two-family turned single, or a downtown building with an added apartment, and those conversions often left the chimney serving the home in ways that no longer match how it is used. A camera inspection is the quickest way to confirm which flue serves which appliance and whether the current setup is safe, which is easy to lose track of in the city’s older, much-modified housing.
Common Chimney Problems in Marlborough Homes
In Marlborough’s older downtown and French Hill housing, we most often find worn crowns, open mortar, and aging or shared liners on tall multi-unit chimneys, where one defect can affect more than one apartment. In the 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 sorts it out either way. On a multi-unit chimney we document each flue separately; on a single-family home we give you a clear read on the fireplace or stove venting, so you know what is safe and what needs work.
Services We Provide in Marlborough
Everything we do at our other Central Massachusetts jobs, we do in Marlborough:
- Chimney sweeping and cleaning: creosote and debris removal matched to your specific flue type, with a camera inspection included.
- Camera-assisted inspections: Level 1, 2, and 3, photo-documented so you see the findings for yourself.

- Caps, chase covers, and waterproofing: custom-fit covers and sealing to keep water, animals, and debris out of the flue.

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.
Marlborough sits on the Route 20 corridor near Interstate 495, and from the same trucks we serve the surrounding towns, including Hudson, Northborough, Southborough, Berlin, and Westborough.
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 you own or manage property in Marlborough and the chimney is overdue for a sweep, has never been camera-inspected, or is showing cracked mortar or a poor draft, call On Duty at (978) 696-7933 or book online. We will document every flue and give you a clear plan.
Frequently Asked Questions about General Fireplace Repair
Do you work on Marlborough's older multi-family homes near downtown?
Yes. Tall masonry chimneys serving more than one unit, common in the downtown and French Hill neighborhoods, are some of the most frequent work we do. We camera each flue separately and document its condition.
I own a rental on French Hill. Can you provide documented inspections?
Yes. For multi-unit buildings we camera each flue and provide a photographed report you can keep on file and share with tenants or inspectors, which is often what landlords need to show the venting is safe and code-compliant.
My Marlborough home is a newer single-family. Do I still need a chimney inspection?
If your 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 Marlborough 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.
Can you service several units or properties in one visit?
Yes. For multi-unit buildings, or owners with more than one property, we can inspect and sweep multiple flues on a single scheduled visit and provide one consolidated, photo-documented report. That keeps recordkeeping simple and helps show every unit’s venting is safe.
