Before summer heat and storms hit Highlands, a quick exterior check and cap inspection can prevent costly damage. Learn what you can safely do yourself and the red flags that mean it’s time to call Marcus T Chimney Inc.
Step 1: Clear debris from the chimney top and check the cap
Stand back and look up at your chimney from the ground in Highlands. Remove any sticks, leaves, or pine needles resting on the chimney cap with a broom or leaf blower. A clogged cap can trap moisture and block airflow. If the cap is bent, rusted, or missing, order a replacement online or at a local hardware store. Never climb onto the roof yourself—Highlands’ summer storms can make shingles slick and gutters unstable. For a full cap inspection or replacement, contact us to schedule a visit.
Step 2: Inspect the exterior masonry for cracks or gaps
Walk around your home and look closely at the chimney’s brick or stone. Use a flashlight to check for hairline cracks, missing mortar, or white crusty stains (efflorescence). Small cracks can let water seep in, freeze in winter, and widen over time. Fill shallow gaps with exterior-grade masonry caulk, but stop if you see deep cracks or leaning bricks—these need a pro. Highlands’ salty sea air speeds up masonry wear, so a quick seal now buys you time. For a full waterproofing quote, see our masonry sealing guide.
Step 3: Test the chimney damper for smooth operation
Open your fireplace and reach up to feel the damper handle. Slide it back and forth to make sure it moves freely and seals tightly when closed. A stuck damper can’t stop drafts or rain from entering your flue. If it’s stiff or won’t close, don’t force it—Highlands’ humidity can warp metal over time. A quick spray of silicone lubricant on the hinge may help, but if the issue persists, schedule a damper repair.
Step 4: Check the chimney flashing for rust or separation
Look where the chimney meets the roof line. Flashing should lie flat against both surfaces with no gaps. Rust spots or peeled edges mean water is sneaking in. You can dab a bit of roofing cement over small holes with a putty knife, but Highlands’ wind-driven rain can lift improper repairs. If the flashing is loose or corroded, call a roofer or our team to reseal it properly.
Warning signs your Highlands chimney needs a pro now
Stop DIY work and call us immediately if you see creosote buildup (black, tarry stains inside the flue), white powdery stains on bricks (efflorescence), a strong campfire smell in summer, or smoke drifting into the room when the damper is open. These signs often point to a blocked flue, cracked liner, or hidden water damage. Highlands’ older homes are especially vulnerable to hidden deterioration. See our warning signs guide for more details.

Frequently Asked Questions
My Highlands chimney smells like campfire even in summer—why does this happen and what should I do?
That campfire odor usually means creosote is trapped in your flue. Highlands’ humid summers trap moisture, which mixes with soot and creates a musty smell. A professional cleaning removes the buildup and restores airflow. Don’t mask the smell with air fresheners—call us to inspect the flue and clean it safely.
Why does my chimney cap in Highlands keep filling with leaves so fast after every storm?
Highlands’ summer storms come with strong winds that funnel debris straight into open caps. A mesh cap with 1/4-inch holes blocks leaves while still letting smoke escape. If yours is wide open or rusted, replacing it with a screened cap can save you repeated cleanups. We install durable caps built for coastal weather—see our cap guide.
Can I waterproof my Highlands chimney myself using a spray can from the hardware store?
A spray can waterproofing product can work for small patches, but Highlands’ salt air and frequent storms demand a professional-grade sealant applied with the right tools. Our team uses vapor-permeable formulas that let bricks breathe while blocking water. DIY sealants can trap moisture inside, leading to bigger cracks. For a lasting solution, request a waterproofing estimate.
