A chimney in Markham 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.
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.
Older Markham chimneys were lined with clay tiles that expand and contract with every fire. A bitter-cold flue meeting a hot fire, season after season, cracks tiles and opens gaps at the joints. Those faults hide inside the chimney, which is why we diagnose liners on camera, not by guessing.
On the coldest mornings, a chimney full of cold, heavy air can push down instead of drawing up, so the first fire in a Markham 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.
An open flue in spring and summer is shelter, and raccoons, birds and squirrels nest in chimneys across Cook County while the fireplace sits idle. A nest blocks the draft, holds moisture against the liner, and can push smoke and carbon monoxide into the room. We clear blockages and fit screened caps.

Same-day service, free estimates, licensed & insured — and a flue you can see on camera, clean from top to bottom.
Water soaks into brick, mortar and the crown, freezes, expands, and opens cracks a little wider with every cycle. Over a few Markham winters that spalls brick faces, splits crowns and crumbles mortar joints, and the gaps let in still more water. Caught early it is repointing and crown repair; ignored, it becomes a rebuild.
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.
Real enough that sweeping is scheduled around it. Creosote builds on the flue walls with every fire, and a hot fire can ignite the glazed layer, turning the flue itself into a fire that cracks tiles and damages masonry. Annual sweeping, dry wood, and hot rather than smoldering fires all lower the risk a great deal.
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.
Not until it has been looked at. Cracked flue tiles, gaps in mortar, creosote buildup and freeze-thaw damage are all invisible from the room. An inspection checks the firebox, flue and chimney top end to end, gives you a plain-language report, and tells you honestly what is sound and what needs work before the first fire.
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.
