Foundation Repair in Carrollton
When Carrollton homeowners find a new crack or a sloping floor, one of the first questions is why. Clay soil movement is the most common culprit in North Texas, but a plumbing leak under the slab can also cause or worsen foundation problems, and the fix (and who pays) can be different. This page walks through that question, then covers costs and local companies.
Soil movement or a slab leak?
Signs that a plumbing leak may be involved: - Your water bill jumps without explanation. - Warm or damp spots appear on the floor. - You hear running water when every fixture is off. - Your water meter keeps moving with everything turned off.
Signs that point more toward soil movement: - Cracks or sticking doors that get better or worse with the seasons. - Gaps around the perimeter after long dry spells.
Neither list is proof. A plumber's leak or pressure test plus an engineer's evaluation gives you the real answer. If a leak is found, fixing it before (or along with) any foundation repair makes sense. Otherwise the soil may keep moving.
What about insurance?
Policies vary, so read yours or call your agent. Common patterns, which aren't guaranteed for your policy: - Many homeowners policies exclude settling and soil movement. - Some policies cover certain damage from a sudden plumbing leak, and sometimes the cost of accessing the pipe.
Document everything with photos, plumber reports, and engineer reports before you file.
