Foundation guides for Collin County homeowners

Start with what you're seeing or deciding. Each guide explains how foundations on North Texas clay behave, what the options are, what they cost and when to bring in an independent engineer. General information only: none of it is a diagnosis of your home.

Signs of foundation problems

The common warning signs on Collin County's expansive clay, from sticking doors to stair-step brick cracks, what engineering groups say is often cosmetic, how the seasons change what you see, and when to call an independent engineer.

Foundation cracks: what's normal

What Texas engineering groups say about hairline, shrinkage and stair-step cracks, the crack traits they pay attention to (width, offset, pattern, growth), cracks often blamed on the foundation that have other causes, and a simple way to log a crack over time.

Sourced, dated price ranges for foundation repair, with national figures kept separate from local contractor figures, plus the engineer, permit and testing costs that often sit outside the headline price.

Pier and beam vs slab

How to tell which foundation your house has, how slabs and pier and beam floors each respond to expansive clay, the repairs engineers typically consider for each, what a post-tension slab is, and what housing age by city suggests.
