A chimney in LaCoste is not fighting a long winter - it is fighting clay soil that shifts under the masonry, heavy rain looking for a way in, storm damage up top, and long idle months in between. This is what we actually find, and what we check on every visit.
Much of Texas sits on clay soil that swells when wet and shrinks when dry, so foundations and chimneys move a fraction at a time, season after season. Masonry cannot flex, so the movement opens mortar joints, cracks crowns, and can leave a chimney leaning. We check joints and alignment on every inspection.
Winters here are mild, but the rain is not - long, heavy rains find every weak cap, cracked crown and failed flashing joint in LaCoste. Water down the flue rusts the damper, stains the firebox, and soaks masonry that then dries slowly in the heat. We trace leaks from the top down.
Long, hot summers bake chimney crowns, dry out sealants, and age cap metal across LaCoste, while sudden downpours test every crack the heat opened. Crowns that looked sound in spring can be split by fall. We check the crown, cap and flashing together, because heat and rain work on all three.
Where a chimney passes through the roof, flashing is the seal - and shifting masonry and storm wind both work it loose in Texas. Failed flashing is one of the most common leak sources we find, showing up as ceiling stains near the fireplace. We check the flashing line on every leak call.

Yes - it is one of the main masonry problems we see in LaCoste. Clay soil swells when wet and shrinks when dry, moving the footing a fraction at a time. Masonry cannot flex with it, so mortar joints open, crowns crack, and chimneys can lean. Caught early, joint repair holds; ignored, it becomes structural work.
Yes, especially the top. Hail dents and cracks caps, storm wind lifts flashing and tears loose caps off entirely, and none of that damage is visible from the ground or the firebox. An open or damaged cap lets rain and animals straight in. We inspect the top, clear any debris, and refit what the storm damaged.
Most often a damaged or missing cap, a cracked crown, or failed flashing where the chimney meets the roof. Heavy Texas rain tests all three at once, and heat-cracked crowns give it an easy path. We trace the entry point from the top down and repair the actual source, not just the stain inside.
Get it inspected promptly. A lean usually means the soil under one side moved more than the other, and the same movement is cracking mortar and opening the joint where the chimney meets the house. Early movement can often be stabilized with joint and flashing repair; a lean left for years becomes a rebuild.
Not until it has been inspected. In LaCoste an idle flue collects nests, debris and moisture, and the masonry may have cracked from soil movement while nobody was watching. One camera inspection tells you whether the flue is clear and the liner sound - before the first fire tests it the hard way.
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.
