Before calling a chimney sweep in Bloomington, check for simple fixes like blocked caps or cracked bricks, but stop if you see sparks, smoke in the house, or a musty smell. Older homes here often hide creosote buildup or failing liners behind obvious signs. When in doubt, call a pro.
Myth: ‘If the fire burns fine, the chimney’s fine’: What Bloomington Homeowners Get Wrong
A roaring fire doesn’t mean your chimney is clear. Many older Bloomington homes with brick chimneys develop hidden issues like cracked flue tiles or rusted dampers. Start by inspecting the damper, if it’s stuck open or closed, cold air drafts or smoke backflow can occur. For brick chimneys, look for spalling bricks (flaking edges) near the roofline, common after Minnesota winters. If you spot these, note the damage but don’t touch it, brick repair requires mortar expertise and structural checks. Read more about masonry repairs in Bloomington homes here.
Step-by-Step: Safe DIY Checks for a Fussy Chimney (Do These First)
1. Clear debris from the cap: Use a broom or stiff brush to remove leaves, twigs, or nests. Never climb onto the roof yourself, use a long tool or call a handyman if needed. 2. Check the smoke chamber: Shine a flashlight up the flue (from the fireplace) to spot creosote buildup or obstructions. Light-colored, tarry residue means it’s time for a chimney sweep, dark, glassy creosote is a fire hazard. 3. Test draft flow: Light a match near the fireplace opening and watch the flame. If it flickers sideways or smells like gas, your chimney lacks proper draw, often due to a blocked flue or wrong-sized liner. For older homes, double-walled stainless steel liners (installed by pros) solve this better than DIY fixes.
Red Flags in Your Chimney: When a Bloomington Sweep is Non-Negotiable
Stop DIYing if you see: Sparks or embers shooting out (sign of creosote or a failing liner), smoke filling the room (blocked flue or cracked masonry), or a strong, musty odor (moisture damage or animal nests). Older brick chimneys in Bloomington often develop hidden cracks that let rainwater seep in, weakening mortar over time. If your chimney is older than 30 years, it may have an asbestos liner, never disturb it yourself. Learn about creosote removal safety here.
What You Should Never DIY, and Why Bloomington’s Old Homes Make It Riskier
Avoid these dangerous tasks: Removing creosote (it’s flammable and toxic), repointing mortar (requires specialized tools and knowledge), or installing a new liner (improper sizing causes draft issues). Bloomington’s older homes often have unreinforced brickwork that can collapse if tampered with. Even cleaning inside the flue with a wire brush can dislodge debris into your home. See our pricing for professional sweeps, it’s cheaper than a house fire or carbon monoxide poisoning.

Frequently Asked Questions
My fireplace smells like gas when it’s off, what’s causing that rotten-egg stench?
This usually means your chimney isn’t drawing properly, often due to a blocked flue or improperly sized liner. Older homes here sometimes have downsized flues that can’t handle modern fireplaces. A smoke test (done by a pro) will confirm the issue. See our service areas to find a local expert.
Why does my brick chimney leak water after every rain, even with a cap?
Caps alone won’t stop leaks if the mortar between bricks is crumbling, common in Bloomington’s older homes after freeze-thaw cycles. Water seeps through cracks, then freezes and expands, worsening damage. A repointing job (sealing mortar joints) is needed, but DIY fixes like caulk won’t last. Learn about masonry repairs here.
Can I light a fire after a sweep if they say ‘it’s clean’?
Yes, but only if the sweep confirmed no creosote stage 2 or 3 (glassy or tarry buildup). Even ‘clean’ chimneys can have hidden cracks or liner gaps, test with a small fire first. If smoke backs up or you smell gas, extinguish the fire and call a pro. Compare sweep services here to ensure you’re getting a thorough job.
