If your Kensington home has an older brick chimney, creosote buildup, cracks, or water stains are red flags. A certified chimney sweep will inspect your liner, mortar, and flue to prevent fire hazards and water damage—especially important in New Britain’s freeze-thaw winters.
1. Your chimney hasn’t been inspected in over a year — and it’s an older brick home
A chimney inspection is a thorough evaluation of your chimney’s structure, flue, and liner to identify hazards like creosote buildup, cracks, or blockages. For older brick chimneys common in Kensington and New Britain, these issues develop faster due to age and New England’s freeze-thaw cycles. The Chimney Safety Institute of America recommends an annual inspection for wood-burning fireplaces, and every two years for gas or oil systems. If you’re unsure when your last inspection was, it’s time to call a certified sweep. Older masonry absorbs moisture, which expands in winter and can crack liners or dislodge bricks—leading to costly repairs if left unchecked. Schedule your inspection before winter sets in to avoid emergency calls when temperatures drop.
2. You notice black, tarry creosote buildup inside the flue
Creosote is a dark, sticky residue that forms when wood burns incompletely. It’s a major fire hazard, especially in older chimneys with rough masonry that traps soot. If you see black, shiny, or tar-like deposits on your flue tiles or smoke chamber, it’s a sign you need a professional sweep immediately. The National Fire Protection Association warns that creosote buildup is a leading cause of chimney fires. In Kensington, where many homes still use wood for heat, this is a common issue. A certified sweep will remove creosote and check for cracks in the liner that could allow heat to escape and ignite nearby combustibles. Don’t wait until you see smoke or smell burning odors—those are late-stage warnings.
3. Your chimney liner has cracks, gaps, or missing sections
A chimney liner protects your home from heat transfer and corrosive byproducts. In older Kensington homes, clay tile liners often crack due to age or shifting foundations, while metal liners corrode from condensation. If you’ve noticed smoke entering your living space, hear a rumbling sound during use, or see daylight through the chimney crown, your liner is compromised. Repairing or relining a chimney is a job for a certified professional, not a DIY fix. We recommend a video inspection to assess the liner’s condition—especially before relining, which can cost between $2,000 and $5,000 depending on materials and chimney height.

4. Water stains appear on your chimney’s exterior or interior walls
Water is the silent enemy of older brick chimneys in New Britain’s humid summers and icy winters. If you see white efflorescence (salt deposits) on your bricks, peeling paint near the fireplace, or musty odors in your living room, your chimney is leaking. Common culprits include a cracked chimney crown, missing or damaged chimney cap, or deteriorated mortar joints. Left unaddressed, water can erode the flue liner, weaken the masonry, and even cause interior structural damage. A professional sweep will identify the source and recommend repairs like repointing mortar or installing a new crown. Protect your chimney with a cap.
5. Your fireplace or stove isn’t drafting properly — or smells like smoke
If smoke is backing up into your home when you light a fire, or you notice a persistent smoky odor even when the fireplace isn’t in use, your chimney’s draft is compromised. This could be due to a blocked flue, improper liner sizing, or negative air pressure in your home (common in older, tightly sealed Kensington houses). A certified sweep will perform a Level 1 inspection to check for obstructions, measure draft, and ensure your chimney meets the NFPA 211 safety standards. Ignoring draft issues can lead to carbon monoxide buildup, a silent and deadly threat. Contact us for a draft assessment.
6. Your chimney crown is cracked or missing chunks
The chimney crown is the concrete or mortar cap that sits atop your chimney, shielding the flue and bricks from rain, snow, and debris. In Kensington, where freeze-thaw cycles are harsh, crowns often crack or crumble over time. A cracked crown allows water to seep into the masonry, accelerating deterioration. If you see gaps, missing pieces, or vegetation growing from the top of your chimney, it’s time for repairs. A professional can rebuild the crown with a durable, waterproof material to prevent further damage. Replacing a crown typically costs between $1,000 and $2,500, depending on size and accessibility. See our masonry repair options.
7. Your chimney hasn’t been swept in over a year — or you’ve never had it professionally cleaned
Even if your chimney looks clean, creosote and soot can accumulate in hard-to-see areas like the smoke shelf or flue tiles. The EPA’s Burn Wise program recommends professional sweeping at least once a year for wood-burning systems, or more often if you burn unseasoned wood or use your fireplace frequently. In older Kensington homes, where chimneys may have rough masonry or offset flues, debris can collect faster. A professional sweep will also check for animal nests, debris, or structural issues that could block airflow. Skipping this step risks fire hazards, poor indoor air quality, and costly repairs down the line. Book your cleaning today.

Frequently Asked Questions
My chimney in Kensington has white stains on the bricks. What’s causing this, and is it serious?
Those white stains are efflorescence, caused by water evaporating and leaving mineral deposits behind. While not immediately dangerous, it signals your chimney is absorbing moisture, which can lead to cracks, liner damage, or interior leaks. A certified sweep will identify the source—often a cracked crown or missing cap—and recommend repairs to prevent further deterioration.
Why does my older Kensington home’s chimney smell like a campfire even when I’m not using it?
A smoky odor in an unused fireplace usually means creosote is coating the flue or smoke chamber, or there’s a draft issue pulling air downward. Older chimneys with rough masonry or offset flues trap odors more easily. A professional inspection will determine if sweeping, liner repairs, or a draft test is needed to eliminate the smell and ensure safety.
How can I tell if my chimney liner needs repair before winter hits in New Britain?
Signs include smoke entering your home, a rumbling sound during use, or visible cracks in the liner during a video inspection. Older clay tile liners often crack with age, while metal liners corrode from condensation. If your liner is damaged, repairing or relining it before winter is critical to prevent heat transfer to nearby combustibles and avoid costly emergency repairs.
What’s the difference between a Level 1 and Level 2 chimney inspection, and which does my Kensington home need?
A Level 1 inspection is the standard visual check for accessible areas, recommended annually for well-maintained chimneys. A Level 2 inspection includes a video scan of the flue and is required after a chimney fire, when changing fuel types, or if you’ve had structural changes to your home. For older Kensington homes with unknown maintenance history, a Level 2 inspection is the safest choice to identify hidden damage.
