A safe chimney self-inspection starts with checking the exterior and accessible interior for obvious damage or blockages. Stop and call a pro if you see cracks, leaning, or heavy creosote buildup—these are signs your chimney needs expert attention.
Step 1: Check the Chimney Exterior from the Ground
Stand back from your Highlands home and look up at the chimney. Use binoculars if needed. Look for missing or damaged bricks, cracks wider than a credit card, or a leaning chimney. Also check the chimney cap—it should be secure and free of debris. If you spot any of these issues, stop here and call us to schedule a professional inspection. Highlands’ coastal winds and salt air can accelerate wear, so early detection is key.
Step 2: Inspect the Flue from Inside the Fireplace
Put on gloves and use a flashlight to look up the flue from inside your fireplace. Look for creosote buildup (black, tarry, or flaky deposits), cracks in the flue liner, or obstructions like bird nests. If you see more than 1/8 inch of creosote or any cracks, do not use the fireplace and contact us immediately. Highlands homes with older chimneys often have fragile liners that need expert care.
Step 3: Check the Chimney Crown and Flashing
The chimney crown is the concrete or mortar cap at the top of the chimney. Look for cracks or missing pieces—water can seep in and cause major damage. The flashing (the metal seal where the chimney meets the roof) should be intact and sealed. If you notice gaps or rust, these are red flags. Highlands’ heavy rains can exploit even small flaws, leading to leaks and structural issues.
Step 4: Look for Water Damage Inside Your Home
Walk around your fireplace and check for water stains on the walls or ceiling nearby. Also, inspect the attic or crawl space near the chimney for moisture or mold. Water damage often points to a leaky chimney or flashing. If you find any, stop using the fireplace and schedule a repair with us right away. Highlands’ humid climate makes moisture issues worse over time.
What You Should NEVER DIY — and Why
Never climb onto your roof to inspect the chimney—Highlands’ steep roofs and coastal winds make this extremely dangerous. Also, avoid using tools to scrape creosote yourself; improper cleaning can damage the flue liner or release toxic fumes. Never seal cracks with regular caulk or mortar—this can trap moisture and worsen damage. These jobs require licensed professionals with the right training and insurance.
WARNING SIGNS: Stop DIY and Call a Pro
If you see large cracks in the chimney structure, a leaning chimney, heavy creosote buildup (more than 1/8 inch), or signs of a chimney fire (like warped metal or cracks in the flue), stop all DIY efforts. Also, if you smell smoke indoors when the fireplace isn’t in use, call a pro immediately. These signs indicate serious hazards that could lead to fire or carbon monoxide poisoning. Highlands homeowners should never ignore these warnings.

Frequently Asked Questions
My chimney in Highlands smells like a campfire even when I haven’t used it in months—what’s causing this?
That smell is likely creosote buildup or trapped moisture. Creosote absorbs odors and releases them when humidity rises, common in Highlands’ coastal climate. A professional cleaning and inspection will clear the buildup and check for leaks causing the moisture.
Why does my chimney in Navesink have white stains on the bricks, and is this dangerous?
Those white stains are efflorescence, caused by water evaporating and leaving mineral deposits. While not immediately dangerous, they signal water is entering the chimney. Over time, this can weaken the structure and lead to cracks or mold. Have a pro assess the flashing and crown.
I live near the Navesink River—how often should I have my chimney inspected in Highlands due to the salty air?
Highlands’ salty, humid air accelerates corrosion and moisture damage. We recommend an annual inspection and cleaning to catch early signs of wear. If your chimney is older or exposed, consider a bi-annual check to prevent costly repairs.
