At Kenji M. Chimney Inc, we don’t just clean chimneys—we protect Haverhill homes from silent threats like creosote buildup, cracked flues, and carbon monoxide leaks. Our team combines decades of local expertise with state-of-the-art tools to ensure your chimney meets Massachusetts fire safety codes, giving you peace of mind every time you light a fire. Whether you’re in a historic Haverhill triple-decker or a modern Andover ranch, we treat every flue like it’s our own family’s chimney.

We strictly follow National Fire Protection Association standards. We do not cut corners; we meticulously document every inspection to ensure your home's ventilation system meets all safety benchmarks.

Inspect your chimney within 24 hours of a heavy snowfall. Ice dams can trap moisture against masonry, accelerating cracks, while snowpack can hide creosote buildup or block the flue entirely. Kenji M. Chimney Inc offers same-day emergency checks for Haverhill homes to prevent water damage or carbon monoxide risks before the next thaw.
A Level 1 inspection covers visible flue interiors and accessible components—standard for routine maintenance in Haverhill. A Level 2 adds a video scan of the entire flue, required after a chimney fire, major renovation, or when selling your Bradford Street property. We use high-definition cameras to document conditions for insurance or real estate transactions.
Haverhill’s historic triple-deckers and pre-1950s homes often have unlined or clay-tile flues that degrade faster due to freeze-thaw cycles and acidic creosote. Relining with stainless steel or cast-in-place systems restores safety and efficiency, especially in homes with original masonry that wasn’t built to modern code standards.
Absolutely. A cracked crown lets water seep into the masonry, freezing and expanding to split bricks or erode mortar joints. Over time, this can lead to costly foundation repairs in Haverhill’s older neighborhoods like Lakeview. We seal crowns with a waterproof, breathable coating to block moisture while allowing trapped water to escape.
Use only seasoned hardwood (oak, maple, or ash) cut to fit your firebox, and keep the damper fully open until embers are cold. Never burn treated wood, trash, or wet logs—these increase creosote buildup and carbon monoxide risk. Kenji M. Chimney Inc can inspect your flue before the storm season to ensure it’s clear and safe for emergency use.
Watch for signs like white, chalky stains on bricks (efflorescence), a musty odor near the fireplace, or soot falling into the firebox. If your damper sticks or the flue liner feels rough to the touch, call us for a pre-season inspection. We prioritize Haverhill homes in September to catch issues before the first frost.
Yes—trapped creosote and moisture create a campfire-like odor when humidity rises. This smell often fades after a thorough sweeping, but persistent odors can signal a hidden leak or blockage. We use specialized vacuums and deodorizing treatments to eliminate smells in Haverhill homes, even in older chimneys.
Turn off your fireplace immediately and cover the firebox with a tarp to prevent water entry. Then call us for an emergency repair—we’ll seal cracks in the crown or flashing and install a chimney cap to block future leaks. Haverhill’s freeze-thaw cycles make quick action critical to avoid structural damage.
