Before Lexington’s summer humidity and storms hit, clear debris, check for blockages, and inspect for damage. Skip risky DIY—call Tulip Chimney Co for a licensed sweep and inspection.
Clear the flue and check for blockages
Use a flashlight to peer up the flue from the firebox. If you see bird nests, leaves, or soot piles taller than your palm, remove them with a chimney brush or shop vacuum—never climb on the roof yourself. Lexington’s spring winds often drop debris that blocks airflow and traps moisture. After clearing, run a shop vacuum with a hose attachment inside the firebox to catch loose soot. If the blockage feels solid or you hit resistance, stop and call a pro—you may have a collapsed flue liner or heavy creosote buildup. blog/7-lexington-creosote-removal-signs-heavy-buildup-edition/ Learn more about our full list of services.
Inspect the exterior for summer storm damage
Walk around your chimney on the ground and look for leaning bricks, cracked mortar, or missing cap pieces. Lexington’s spring storms can loosen caps or crack crowns, letting water seep in and rust the damper. Check the flashing where the chimney meets the roof—rust rings or gaps mean water is already working its way into your walls. If you spot cracks wider than a credit card or see daylight through the bricks, schedule a repair before summer humidity sets in. services/ See request a free estimate / contact us.
Test the damper and clean the firebox
Open and close the damper fully to ensure it moves freely. If it sticks or won’t close all the way, spray the hinges with silicone lubricant—never WD-40, which can gum up the mechanism. Scoop out old ash and debris from the firebox using a metal shovel and bucket; never use a household vacuum that isn’t rated for soot. Lexington homeowners often overlook ash piles that can smolder and ignite creosote. After cleaning, wipe the firebox walls with a damp cloth to remove loose soot—this reduces dust when you next use the fireplace. Explore about our team and credentials.
Warning signs that mean call a pro now
Stop DIY work if you see white, chalky stains on the bricks (efflorescence), puffs of smoke spilling into the room when the damper is open, or a strong campfire smell even with the flue closed. These signals point to water damage, cracked liners, or dangerous creosote levels. Another red flag: animals or insects entering through the flue—raccoons and squirrels often nest in Lexington chimneys after winter. blog/lexington-chimney-inspection-safety-what-to-expect-during-a/ For details, see the areas we serve.
When to Call Tulip Chimney Co
If your Lexington chimney hasn’t been swept in the last 12 months, shows any warning signs above, or you’re unsure about the flue’s condition, book a certified sweep and inspection. Tulip Chimney Co’s team uses video scanning to check for hidden cracks and creosote layers in Lexington homes. We also waterproof crowns and replace damaged caps to protect against summer storms. contact/ pricing/
Lexington-specific seasonal prep checklist
Before Memorial Day, remove the winter ash pile, check the cap for rust, and confirm the damper seals tight. If your chimney is on the east side of your Lexington home, watch for morning dew that can accelerate rust on the damper. For chimneys near Lexington Woods or the Battle Green area, schedule a sweep early—tree pollen and dust clog flues faster. Keep a tarp handy to cover the firebox during summer storms to prevent water from pooling inside.

Frequently Asked Questions
Should I clean my Lexington chimney myself after seeing a little soot in the firebox?
No—light soot can hide heavy creosote buildup behind it. Lexington’s cold winters often leave thick, tarry layers that require professional removal to prevent chimney fires. Call Tulip Chimney Co for a certified sweep instead of risking a DIY brush job.
Is it worth climbing on the roof to inspect my Lexington chimney cap after a storm?
Never climb yourself—Lexington roofs are steep and slate tiles can crack. Instead, use binoculars from the ground to check the cap and flashing. If you spot damage, services/
Do I really need a chimney inspection in Lexington if I didn’t use the fireplace all winter?
Yes—even unused chimneys collect debris and moisture. Lexington’s humidity can cause rust in dampers and liners without you knowing. A standard inspection by Tulip Chimney Co costs less than a repair and keeps your chimney ready for next fall.
