A chimney in Merrillville 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 Merrillville 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 Merrillville 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.
An open flue in spring and summer is shelter, and raccoons, birds and squirrels nest in chimneys across Lake 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.
Much of the housing stock in Merrillville pairs older masonry chimneys with homes that have been tightened, insulated and remodeled over the years. That mismatch causes downdrafts and smoke problems, while the aging mortar and tile need checking on their own. Our techs read both problems together and correct the cause.

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.
From the room, usually you cannot - cracked tiles sit inside the flue, above the firebox. Signs can include a smoke smell in upstairs rooms, bits of tile in the firebox, or a fireplace that drafts worse after years of good service. A camera inspection shows the tile condition directly and gives you a report in plain language.
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.
Meltwater is the usual cause in Merrillville: snow and ice sit on the crown, then thaw water soaks into split crowns, open mortar joints and failed flashing, showing up as stains, peeling or a damp smell indoors. We trace the entry point from the top down and repair the actual source, not just the stain.
Do not light a fire. Raccoons, birds and squirrels nest in open flues across Indiana 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.
