Frisco Foundation Repair Co. connects homeowners who need slab foundation repair in Frisco, TX with an independent local foundation company that can measure the slab, find the cause and lift what has dropped.
Frisco grew faster than almost any city in the country over the last two decades, and nearly all of that growth was built on concrete slabs. A newer house is not immune to foundation movement. The clay under Collin and Denton counties moves whether a house is five years old or fifty.
Post-Tension Slabs: What Frisco Owners Should Know
Many newer North Texas houses sit on post-tension slabs. Steel cables run through the concrete and are tightened after it cures, which helps the slab resist cracking. That matters for repair in two ways:
- Cables must not be cut. Drilling, coring or tunneling through a post-tension slab without locating the cables can be dangerous and damaging. Ask any contractor how they handle post-tension slabs.
- Cracks behave differently. Post-tension slabs tend to show fewer, tighter cracks, so movement may show up first in drywall, doors and brick rather than in the concrete itself.
Warning Signs Inside and Out
- Drywall cracks running diagonally from door and window corners
- Doors that drift open, rub at the top or will not latch
- Stair-step cracks in brick or stone veneer
- Gaps between the slab and the garage door when it is closed
- Floors that feel off-level, often near one corner of the house
How Slab Repair Works
The contractor takes elevation readings across the house to map the high and low areas. If the slab has dropped, piers are installed under the low sections, typically pressed concrete or steel, and the slab is lifted toward level and shimmed. If part of the slab has heaved, often from a leak or pooled water, the fix usually starts with finding the water source; lifting the rest of the house to meet a heaved section is sometimes part of the plan.
Check Your Builder Warranty First
If your house is new enough, it may still be under a builder's limited warranty that covers major structural defects. Find the warranty paperwork before you hire anyone, and read the claim process carefully; some warranties require you to report problems in writing within a set time and may not cover repairs done by someone else.
Slab Repair Across Frisco's Two Counties
Frisco straddles Collin and Denton counties, and its neighborhoods range from the older blocks around the original downtown to subdivisions finished in the last few years. The slab-repair questions change with age. In older houses, inspectors look harder at plumbing under the slab and at earlier repairs. In newer ones, they check for post-tension cables, lot settlement and builder warranty status before recommending anything.
Common questions
How much does slab repair cost in Frisco?
Most of the price comes from the number of piers. Angi's cost guide lists about $1,000 to $3,000 per pier and an average foundation repair near $4,530. Contractor-reported jobs gathered in a 2026 roundup averaged $11,117 per booked repair in Dallas. Ask for an itemized estimate after an inspection.
Can a new house in Frisco have foundation problems?
Yes. Expansive clay moves regardless of the house's age, and new lots can have fill soil and drainage that is still settling. Movement in the first few years is worth documenting while any builder warranty is active.
Is it safe to repair a post-tension slab?
Yes, when the crew knows it is post-tensioned and avoids the cables. Exterior piers along the beam are common, and interior work is planned around cable locations.
Will lifting the slab fix my drywall cracks?
It relieves the stress that caused them, and some may close partly, but most homeowners still patch and paint afterward. Ask what touch-up is included.
Should I get a plumbing test first?
Often, yes. A leak under the slab can cause heave in one area. A plumbing leak test before repair tells the contractor whether water is part of the problem.
Does Frisco require a permit for slab repair?
Permit rules depend on the work and can change. Ask the contractor whether your job needs a City of Frisco permit and who will pull it.
