Before Sharon’s summer humidity sets in, clear debris, check for cracks, and inspect your chimney cap. These simple steps protect your home from water damage and keep your fireplace safe for fall. Don’t wait—summer prep prevents costly repairs.
Clear debris and check the chimney cap
Start by removing leaves, twigs, and bird nests from the chimney cap and flue. Use a sturdy ladder on level ground and wear gloves. If the cap is bent or missing, water can enter the flue, causing rust and masonry damage. Replace a damaged cap immediately—this is a safe DIY task, but if the cap is cracked or the flue is blocked, stop and call a pro. Sharon’s summer storms can push debris deep into the flue, so clear it now to avoid clogs that trap moisture and accelerate wear. Learn more about chimney caps and crowns
Inspect the exterior for cracks and water stains
Walk around your chimney and look for cracks in the masonry or white, chalky efflorescence on the bricks. These signs mean water is seeping in. Use binoculars to spot damage on the roof or higher sections. If you see gaps wider than a credit card or crumbling mortar, don’t seal them with caulk—this can trap moisture and worsen damage. Instead, document the issue and call a pro. Sharon’s freeze-thaw cycles in spring make cracks worse fast, so early detection saves money. See our masonry repair guide for Sharon homeowners
Test the damper and flue before summer humidity sets in
Open and close the damper a few times to ensure it moves freely. If it sticks or won’t stay open, the mechanism may be corroded or misaligned. Lubricate the hinge with a dry, heat-safe lubricant if needed. Next, shine a flashlight up the flue from the fireplace. Look for soot buildup or obstructions. If the flue is coated in black, tarry creosote, do not attempt to clean it yourself—creosote is flammable and requires professional removal. Sharon’s humid summers can worsen creosote buildup, increasing fire risk. Find out how often to service your chimney in Sharon
Warning signs that mean call a professional now
Stop all DIY work and call a licensed sweep immediately if you see these signs: persistent smoke smells indoors, white or rust-colored stains on the chimney exterior, or puffs of smoke leaking into the room when the damper is open. These indicate a blockage, cracked flue liner, or damaged chimney crown. Never ignore a collapsed or missing chimney cap—Sharon’s summer storms can drive rain straight into the flue. Other red flags include loose bricks, a leaning chimney, or soot falling into the fireplace. These issues can lead to carbon monoxide leaks or chimney fires.

Protect your chimney from Sharon’s summer humidity
After clearing debris and checking the cap, consider applying a waterproofing sealant designed for masonry. Use a product labeled for chimneys and follow the manufacturer’s instructions. Apply it on a dry, overcast day to prevent trapping moisture inside the bricks. Avoid painting the chimney with regular exterior paint—it can trap moisture and cause spalling. Sharon’s high humidity and occasional thunderstorms make waterproofing a smart summer project. If you’re unsure about the condition of your chimney, let a pro assess it first.

Frequently Asked Questions
My Sharon chimney has white stains on the bricks—what are they and should I worry?
Those white stains are efflorescence, a sign water is evaporating through the bricks and leaving mineral deposits. It means your chimney is absorbing moisture, which can lead to cracks and spalling. While not an emergency, it’s a warning to check for leaks and consider waterproofing. If the stains spread or bricks crumble, call a pro immediately.
Why does my Sharon chimney cap keep filling with leaves even after I clear it?
If your chimney cap fills with leaves quickly, the cap may be damaged or the wrong size. A loose or missing screen allows debris to blow in, especially during summer storms in Sharon. Check the cap’s fit and replace it if it’s bent or rusted. A pro can install a secure, screened cap to keep debris out year-round.
Can I waterproof my Sharon chimney myself with a spray can from the hardware store?
No. Chimney waterproofing requires a breathable, vapor-permeable sealant designed for high-heat masonry. Regular paint or silicone sealants trap moisture inside, causing bricks to crack and spall. Sharon’s freeze-thaw cycles will worsen the damage. Always hire a licensed sweep to apply the right product and ensure proper coverage.
