Small, consistent Highlands chimney habits—like cap checks and creosote monitoring—can add years to your flue and prevent dangerous backups. Start with these safe, low-effort steps today.
Check your chimney cap every Highlands season
A damaged or missing cap lets Highlands rain, leaves, and critters into your flue, speeding up wear. Once a season, use binoculars to inspect the cap from the ground. Look for rust, cracks, or a cap that’s shifted or missing entirely. If you spot damage, call a pro—installing or replacing a cap requires roof work and proper sealing to avoid leaks. A secure cap keeps Highlands moisture out and your chimney lasting longer. blog/chimney-cap-installation-highlands-nj-5-key-steps/. Learn more about our full list of services.
Sweep creosote buildup before Highlands summer heat
Creosote, the sticky tar from wood fires, builds up faster in Highlands’ humid summers. A thin layer can be scraped off with a chimney brush from the firebox, but deeper layers need a pro’s rotary system. Do a quick visual check with a flashlight—if you see black, shiny, or tar-like deposits thicker than a credit card, stop burning and call for a sweep. Burning with heavy creosote risks a Highlands chimney fire. blog/how-often-chimney-service-highlands/. See request a free estimate / contact us.
Inspect mortar joints for Highlands freeze-thaw cracks
Highlands winters freeze water in tiny cracks, then thawing splits masonry wider. Once a year, walk around your chimney and look for crumbling mortar, white mineral stains, or gaps wider than a dime. Use binoculars for the top sections. Small cracks can be filled with high-temperature mortar, but if chunks are missing or the flue liner is cracked, call a pro. Ignoring Highlands’ freeze-thaw cycle can lead to costly rebuilds. blog/chimney-repairs-restoration-highlands-nj-common-issues-solutions/. Explore about our team and credentials.
Keep Highlands critters out of your flue
Squirrels and raccoons love nesting in unused Highlands chimneys. Before lighting your first fall fire, shine a flashlight down the flue from the roof or use a camera on a pole. If you see leaves, twigs, or animal activity, call a sweep to remove the nest and install a critter guard. Never burn a chimney with debris—it can ignite a fire or block deadly carbon monoxide. blog/7-signs-your-highlands-nj-chimney-needs-relining-and-local-fixes/. For details, see the areas we serve.
Waterproof masonry before Highlands’ next storm season
Highlands’ salty coastal air and heavy rains soak brick and mortar, accelerating decay. Apply a breathable, water-repellent sealer every 3–5 years to protect your chimney. Choose a product labeled for masonry and follow the label’s drying times. Never use paint or non-breathable sealers—they trap moisture and cause spalling. Test a small area first to check for color changes. blog/waterproofing-masonry-sealing-highlands-nj-chimneys-7-steps/.
Warning signs your Highlands chimney needs a pro now
Stop DIY work and call a professional immediately if you see: white, chalky stains (efflorescence), leaning more than 2 inches, smoke backing into the room, or a roaring sound during a fire. Also call if your chimney cap is missing or the flue liner is cracked. These signs can mean structural failure, carbon monoxide risk, or a chimney fire hazard. Highlands’ coastal winds and salty air can hide damage—don’t wait for a leak or collapse. blog/chimney-acting-up-highlands-homeowners-safe-troubleshooting/.

Frequently Asked Questions
My Highlands chimney smells like campfire even when I’m not using it—why?
That campfire smell is trapped creosote or moisture in your flue. Highlands’ humid air can make it worse. Try burning a hot fire with dry, seasoned wood to burn off deposits, but if the odor lingers, call a pro. It may need a deep clean or relining to clear hidden buildup.
Why does my Rumson-style brick chimney have white stains after rain?
Those white stains are efflorescence—salts leaching out of your bricks due to Highlands’ salty air and moisture. It’s a sign your chimney is absorbing water. Waterproofing with a breathable sealer can stop it, but if the bricks are crumbling, call a pro to assess structural damage.
Can I waterproof my Atlantic Highlands chimney myself with any sealant?
No. Use only a breathable, water-repellent masonry sealer made for chimneys. Non-breathable products trap moisture and can cause spalling. Test a small area first—some Highlands bricks change color with sealers. For best results, hire a pro to prep and apply the sealer properly.
