Most Buffalo 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 Buffalo 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 Buffalo 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.
Older Buffalo 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.
Lake moisture, summer humidity and meltwater rust the metal a chimney depends on: dampers seize or warp, caps rust through, and flashing loosens as mortar around it fails. A rusted-through cap is an open hole over the flue. We inspect the metal parts most sweeps skip, on every visit.
An open flue in spring and summer is shelter, and raccoons, birds and squirrels nest in chimneys across Wright 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.

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 Minnesota 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.
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.
