Foundation repair in Frisco
A stair-step crack in the brick. A bedroom door that has started to rub. A floor that no longer feels flat. Frisco is built on clay that swells when it is wet and shrinks through a dry summer, and a slab moves with it. Call, say what you have noticed, and book an inspection with an independent local foundation repair company.
A referral service for houses. Findings and prices come from the company you speak with, which is a separate business from this site.

Have this ready when you call
- Where the cracks or gaps are: which wall, which room, inside or out.
- When you first saw them, and whether they have grown or come and gone with the seasons.
- Slab or pier and beam, and roughly when the house was built.
- Anything that changed lately: a plumbing leak, a new pool or patio, a tree taken out.

Under Frisco
Two kinds of ground in one city
A city-hosted regional geology report describes Eagle Ford shale and Austin Chalk near Frisco, with the rock formations changing across the area. The federal soil survey includes expansive clays, soils that crack open in dry weather and close again when it rains. In places the chalk sits only a foot or two down.
That matters when a repair is planned. How deep a pier has to go before it reaches a suitable bearing layer can vary across the city. Why foundations move in Frisco explains what the maps show and how to look up your own lot.

Short answers
Before you call
Is Frisco Foundation Repairs a repair company?
No. It is a referral service. When you call you speak with an independent local foundation repair company, and that company inspects the house, writes the proposal and does any work.
Who tells me what the repair will cost?
The company that inspects your house, in writing, after it has looked. This site never quotes prices. What affects the cost explains what moves the number.
Do I need an engineer's report before I call?
No. Describe what you see and book the inspection. Frisco does require a stamped engineer letter with a foundation repair permit, which the repair company normally arranges. You are also able to hire your own engineer first if you want an opinion from someone who does not sell repairs. See foundation inspections.
I own a rental house in Frisco. Is this number for me?
Yes. Owners and landlords of houses are who the companies want to hear from. If you rent the house you live in, tell your landlord what you have seen. Commercial buildings and contractors looking for work are a different matter and this number will not help.
The crack appeared overnight and the wall has shifted. What now?
Treat sudden movement differently from a crack you have watched for months. Get everyone out, keep away from the wall or chimney involved, and call 911. If you smell gas, leave first and call 911 or the gas utility from outside.
