Foundation repair in Wylie, TX
Wylie nearly quintupled between 1990 and 2010. Here's what that means for its homes, and what to ask the city.
Wylie sits east of Murphy, between Lavon Lake to the north and Lake Ray Hubbard to the south, and spreads across Collin, Dallas and Rockwall counties. Send the form or call (469) 409-4806 and a local foundation repair contractor will get in touch.

Fast growth since 1990
Wylie had 8,716 residents at the 1990 census, 15,132 in 2000 and 41,427 in 2010. That's nearly a fivefold rise in twenty years, and the city added about 6,300 more people between 2020 and 2025. Most Wylie homes are therefore less than 35 years old, with a large group from the 2000s, by our reading of the census counts.
Homes from that building wave may sit on post-tensioned slabs. Before anyone drills or cuts the slab, read what that means for repairs.
Permits
We couldn't confirm the City of Wylie's foundation repair permit rules from its published documents, so we won't guess. Call the city's building inspections department before work starts and ask three things: whether a permit is needed, whether an engineer's letter is required, and whether the contractor must register with the city.
For comparison, nearby Sachse requires engineer-stamped pier plans and Richardson requires an engineer-sealed report for repairs of four or more piers.
The ground
Like most of Collin County, Wylie is on Blackland Prairie clay, which the Texas Water Development Board describes as shrinking and swelling markedly with moisture. Look up your lot on the USDA Web Soil Survey, since soils near the lakes and creeks can differ.
