Somerville homeowners often overlook small fireplace maintenance tasks that lead to big problems. From ignoring creosote buildup to skipping seasonal checks, these mistakes can create fire hazards or costly repairs. Learn what to watch for and how to keep your chimney safe and efficient year-round.
Mistake #1: Assuming your chimney is clean just because you haven’t noticed smoke issues
A chimney inspection is a visual check of your flue and venting system to spot damage, blockages, or dangerous creosote buildup. The Chimney Safety Institute of America recommends an annual inspection, even if your fireplace seems to work fine. In Somerville’s older homes—many built before 1950—hidden cracks or partial blockages are common. A professional sweep uses specialized tools to detect issues that aren’t visible from the firebox. Skipping this step risks chimney fires or carbon monoxide leaks, especially during winter when you rely on your fireplace most. Felix Chimney Company offers free estimates and can schedule your inspection before the cold season hits. Schedule your inspection
What most people get wrong: Thinking a quick brush is enough to remove creosote
Creosote is a tar-like byproduct of burning wood that coats the inside of your chimney. It builds up faster in homes that burn unseasoned or softwoods—common in Somerville where many use fireplaces for ambiance rather than primary heat. A standard chimney sweep removes loose creosote, but thick layers (especially in glazed form) require specialized tools and techniques. Left unchecked, creosote can ignite, causing chimney fires that spread to your roof. The National Fire Protection Association notes that creosote is a leading cause of chimney fires.

Mistake #2: Ignoring the chimney cap—or installing the wrong one for Somerville’s weather
A chimney cap is your first line of defense against Somerville’s unpredictable weather. It keeps out rain, snow, and debris while preventing animals like squirrels or raccoons from nesting in your flue. Many homeowners in Davis Square or Union Square skip this step, assuming their chimney is fine without one. But a missing or damaged cap can lead to water damage, mold, or even a blocked flue during a Nor’easter. Felix Chimney Company installs custom caps that fit your chimney’s dimensions and local climate needs. See our cap installation services
What most people get wrong: Using the wrong wood or burning trash in your Somerville fireplace
Burning the wrong materials—like painted wood, plywood, or even wrapping paper—releases toxic chemicals and accelerates creosote buildup. The EPA’s Burn Wise program warns against burning anything but seasoned hardwood (like oak or maple) in your fireplace. In Somerville, where many homes have older masonry chimneys, burning trash can cause rapid deterioration. Seasoned wood burns hotter and cleaner, reducing soot and extending the life of your chimney. Learn how to choose the right wood
Mistake #3: Skipping the damper check before lighting your first fire of the season
The damper is a metal flap inside your chimney that controls airflow. If it’s stuck closed or damaged, smoke can back up into your home, filling rooms with carbon monoxide—a silent, odorless killer. Many Somerville homeowners forget to test their damper until they smell smoke or notice poor draft. A simple test: Light a small piece of newspaper and hold it up the damper. If the smoke doesn’t rise, your damper may need repair or replacement. Felix Chimney Company offers damper inspections and repairs as part of our full chimney services.
What most people get wrong: Assuming your chimney doesn’t need maintenance if you only use it occasionally
Even if you only light your fireplace a few times a year—common in Somerville’s rental properties or second homes—your chimney still needs attention. Moisture, pests, and seasonal temperature swings can cause cracks or deterioration over time. The Chimney Safety Institute of America recommends sweeping and inspecting chimneys at least once a year, regardless of usage. In Somerville’s humid climate, moisture can seep into unprotected masonry, leading to spalling bricks or mortar failure. Learn how often to schedule a sweep
Mistake #4: DIY repairs without knowing when to call a pro
Somerville’s historic homes often have unique chimney designs, and what looks like a simple crack might hide structural issues. While homeowners can handle minor tasks like cleaning the firebox or replacing a damaged screen, major repairs—like tuckpointing or relining—require professional expertise. Felix Chimney Company is licensed, insured, and familiar with Somerville’s building codes. We offer free estimates and warranties on our work. Contact us for a repair estimate
What most people get wrong: Waiting for a problem to appear before scheduling maintenance
Many Somerville homeowners wait until they see smoke backing up or hear strange noises from their chimney before calling a sweep. By then, the issue is often severe—and more expensive to fix. Regular maintenance catches problems early, saving you money and keeping your family safe. Felix Chimney Company offers seasonal checklists to help you stay ahead. See our summer maintenance tips

Frequently Asked Questions
Why do Somerville chimneys need more frequent maintenance than in other cities?
Somerville’s older housing stock, humid climate, and seasonal temperature swings accelerate chimney wear. Many homes were built before modern building codes, with masonry that’s more prone to cracking or water damage. The Chimney Safety Institute of America recommends annual inspections here due to these local factors.
How can I tell if my Somerville chimney needs a sweep before winter hits?
Look for these signs: a strong, acrid smell when the fireplace isn’t in use; black, tarry buildup on the firebox floor; or difficulty lighting fires. If it’s been over a year since your last sweep, schedule one now—especially if you live near Ball Square or Teele Square, where older homes are common.
Is it safe to use my fireplace after a chimney sweep in Somerville?
Yes, once the sweep is complete and you’ve received a clean inspection report, it’s safe to use your fireplace. Felix Chimney Company provides a detailed report and can answer any questions about your chimney’s condition. Always wait for the sweep to finish before lighting a fire.
What’s the most overlooked fireplace maintenance task in Somerville homes?
Checking the chimney cap. Many homeowners assume it’s fine until they notice water stains on their ceiling or hear animals in the flue. A missing or damaged cap can lead to water damage, mold, or even a blocked flue during a storm—common in Somerville’s unpredictable weather.
