Most Posen chimney calls trace back to the season itself: heavy wood burning laying down glazed creosote, lake-effect moisture keeping masonry damp, and thermal cycling cracking clay flue tiles from the inside. We show you what we found on camera and fix the real cause, not just the symptom.

A chimney in Posen works from the first cold night to the last thaw, then sits damp through a humid summer. Deep freeze-thaw, lake moisture and heavy wood heat do the damage here. This is what we actually find, and what we check on every visit.
Water soaks into a Posen chimney crown, mortar joint or brick face, then freezes, expands, and pries the opening wider. Repeat that cycle all winter and brick faces spall, crowns split, and mortar crumbles to sand. We check the crown, joints and brick on every inspection and catch it early.
Freeze-thaw works mortar joints loose until they recess, crack and fall out in chunks across Cook County. Open joints let more water in, which freezes and opens them further, and heat starts reaching places it should never reach. Repointing sound joints early is a repair; waiting turns it into a rebuild.
A heavy snowfall or ice storm in Posen can bury a chimney cap, load the crown with weight, and leave meltwater soaking into masonry for days. A buried or damaged cap restricts the vent and lets water down the flue. After a big storm is the right time to check the top.
On the coldest mornings, a chimney full of cold, heavy air can push down instead of drawing up, so the first fire in a Posen home spills smoke into the room until the flue warms. A blocked cap, cracked liner or tightly sealed house makes it worse. We diagnose the cause in order.

At least once a year if you burn regularly, and sooner if wood is real heat in your home - roughly every cord burned is a good guide. A long Midwest heating season lays down serious creosote, and the glazed kind is a flue-fire risk. The sweep also checks the liner, cap and damper.
It is serious, because open joints are how water gets in and heat gets out. Spalled brick and recessed mortar let freeze-thaw work deeper every winter, and gaps near the flue let hot gases reach the masonry and framing. Small joint repairs are straightforward when caught early, before the damage reaches the liner.
A flue full of cold, heavy air pushes down until it warms, and a blocked cap, cracked liner or tightly sealed house makes the spill worse. The fix depends on the cause - warming the flue, clearing the cap, repairing the liner, or correcting the pressure. We check them in order instead of guessing.
Be careful, and leave the fireplace off until the top is checked if the cap is buried or the fire burns oddly after a big snow. A blocked cap means the flue cannot vent properly, and exhaust can spill into the room. Once the cap and vent are cleared and checked, the fireplace can go back into service.
Do not light a fire. Raccoons, birds and squirrels nest in open flues across Illinois in spring and summer, and a nest blocks the draft and holds moisture against the liner. Lighting under a blockage pushes smoke and carbon monoxide into the room. We remove the blockage, check for damage, and fit a screened cap.
No — and be wary of anyone who does. Every chimney fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
