A chimney sweep in Bohemia isn’t just about removing soot—it’s about spotting hidden dangers before they start. You can do a basic self-inspection safely, but stop immediately if you see cracks, rust, or excessive creosote buildup. These are red flags that require a licensed pro like Walrus Chimney to fix. Never climb on a roof or poke inside a chimney with tools—leave that to the experts.
Step 1: Spot Exterior Red Flags (No Ladder Required)
Start from the ground. Look for brick or mortar damage—cracks wider than 1/8 inch or crumbling mortar mean moisture is seeping in, weakening your chimney. In Bohemia’s damp winters, this is especially critical. Check for rust stains on the chimney cap or crown (the top edge). Rust indicates water damage, which can lead to structural failure. If your chimney cap is missing or bent, that’s a stop-and-call-a-pro moment. Use our /areas/bohemia/ guide to see common local chimney issues. See everything we handle.
Step 2: Peering Up the Flue (With a Flashlight—Not Your Hands)
From the fireplace, shine a bright flashlight up the chimney. You’re looking for glossy black or tarry buildup—that’s creosote, a flammable byproduct of burning wood. If it’s thicker than 1/8 inch, your chimney needs a professional chimney sweep now. In Bohemia’s older homes, creosote buildup is often worse due to hardwood burning. Never scrape it yourself—creosote can ignite or release toxic fumes. If you see soot blowing back into the room, that’s another red flag. Learn more about creosote dangers in our /blog/bohemia-creosote-removal-full-chimney-sweep-danger-signs/ guide. Learn more about book a visit or ask a question.
Step 3: Checking the Smoke Chamber (The Danger Zone)
The smoke chamber (the area just above the fireplace opening) is where most chimney fires start. If you see large gaps between bricks, missing mortar, or a sagging smoke shelf, these can trap heat and ignite creosote. Do not try to repair mortar yourself—chimney masonry requires specialized skills. If your damper (the metal flap) is rusted or stuck, that’s a call-a-pro job. In Bohemia’s older homes, dampers often fail due to salt air corrosion. See our /services/ for full chimney repair options. There is more in the team behind the work page.
WARNING SIGNS: When to STOP DIY and Call Walrus Chimney
If you spot any of these, do not proceed—they’re fire, carbon monoxide, or structural hazards: - Orange or flickering flames (not the usual blue)—sign of incomplete combustion and possible creosote fire risk. - Strong, sweet-smelling smoke in the house (could mean creosote burning or a blocked flue). - White smoke (indicates moisture condensation, which can rot wood and damage masonry). - Animals nesting in the chimney (birds, squirrels—this means gaps in the flue). - A musty smell when the fireplace is cold (sign of water damage or mold). These issues require a licensed chimney sweep to diagnose and fix safely. Book a visit with us at /contact/. You can also review our towns we cover.
What You Should Never Try Yourself (And Why It Backfires)
Some tasks sound simple but are illegal, dangerous, or void your warranty in Bohemia: - Climbing on the roof to inspect or clean—falls are the #1 cause of chimney-related injuries. - Using a wire brush or vacuum inside the flue—this can dislodge creosote and create a fire hazard. - Ignoring NY’s chimney inspection laws—if your home is in a fire district (like parts of Suffolk County), you’re legally required to have an annual inspection. Check our /blog/chimney-inspection-mandatory-before-fireplace-use-bohemia-ny/ guide for local rules. - Skipping a chimney sweep after a house fire—even if the fire wasn’t in the chimney, soot can corrode metal parts.

Frequently Asked Questions
My chimney looks fine from the outside, but my fireplace smells like wet wood when I light it. Is this normal in Bohemia’s humidity?
No, that’s not normal—it’s a sign of moisture in the flue, which can rot wood and damage masonry. In Bohemia’s damp climate, this often means a cracked crown or missing chimney cap. Stop using the fireplace and call a pro to inspect for water damage. See our /services/ for chimney waterproofing options.
I found a small hole in my chimney cap near the roof. Can I patch it myself with caulk, or will that make things worse?
Never use caulk—it won’t withstand heat or weather. A small hole can let in rain, pests, and creosote buildup, all of which worsen over time. In Bohemia’s windy areas, even a tiny gap can cause structural stress. Replace the cap with a stainless steel model and have us inspect the flue for damage.

My dryer vent cleaning was done last year, but now my clothes take forever to dry. Is this a sign I need another cleaning in Bohemia’s humid summers?
Yes—dryer vent cleaning should happen every 1–2 years, or more often if you notice longer drying times, hot dryer exteriors, or lint near the vent. In Bohemia’s humidity, lint buildup accelerates, increasing fire risk. Schedule a dryer vent inspection before summer heat kicks in. Learn more about dryer vent safety in our /tips/ section.
