Foundation repair in Frisco

Frisco went from about six thousand people to over two hundred thousand in thirty years. One consequence nobody plans for: an enormous number of houses here crossed the ten-year mark at roughly the same time. If you bought new, your structural warranty has probably just run out — or is about to.

A whole city aging out at once

Texas new-home warranties are commonly structured in three tiers — about a year on workmanship, two on major systems, and ten years on major structural components, with the foundation in that last tier. Our Cibolo page sets out how to make a claim while one is live, and that detail is not repeated here.

What is particular to Frisco is the timing. Because the bulk of this housing was completed between roughly 2000 and 2020, the ten-year expiries arrive in an unusually tight cluster. A house finished in 2012 lost structural cover in 2022. A house finished in 2015 lost it this year.

Elsewhere, warranty expiry is an individual event that happens quietly to one household at a time. Here it is closer to a cohort crossing a line together — and most of them have no idea which side of it they are on.

Work out where you are on the clock

Two facts, both in paperwork you already have:

  1. The date it runs from. The warranty document specifies this and it is usually completion or closing rather than the day you moved in — which matters if you bought the house second-hand, because the clock started with the original owner, not with you.
  2. Who administers it. Frequently a third-party warranty company rather than the builder, and frequently a builder that no longer exists under the same name. The administrator is who you would notify.
If you are at year eight or nine, do this now

Get an elevation survey while the warranty is still live. It costs $300 to $800 and takes about an hour. If it finds meaningful movement, you have time to notify the administrator and use a route that is about to close permanently. If it finds nothing, you have a dated baseline for the rest of the house's life — and knowing what your floors measured in year eight is worth a great deal in year fifteen, when the only question that matters is whether something is new. Almost nobody does this, because at year eight nothing appears to be wrong. That is precisely why it works.

If a survey does turn something up and the warranty is live, the one thing not to do is call a repair contractor first. Structural warranties are typically conditioned on the administrator being notified and given the chance to inspect before any work happens, and having piers installed first can reduce or void a claim that would otherwise have paid for the lot. The sequence that protects you is on the Cibolo page.

If it has already expired

Two things are true at once, and it is worth holding both.

You have lost a route to somebody else paying. That is a real loss and there is no point softening it. Whether any other avenue remains open depends on your contract, the circumstances and the timing — that is a question for an attorney, not for a repair contractor and certainly not for a referral site.

But the house is not different on the day after. Most Frisco housing is modern post-tension slab on engineered lots, built to current practice, and it performs well. Expiry is a change in your paperwork, not in your foundation.

How expansive clay moves a slab foundation Two cross-sections of a house on a concrete slab. On the left, wet clay has swollen and pushed the edges of the slab upward. On the right, the clay has dried and shrunk, leaving voids beneath the slab edges so the perimeter drops and the walls crack. After heavy rain Clay swells, perimeter lifts water in clay expands After a drought summer Clay shrinks, perimeter drops void void water out clay contracts, voids open
Expansive clay changes volume with its moisture content. The soil around the edge of a slab wets and dries faster than the soil under the middle, so the perimeter rises and falls the most — which is why foundation symptoms usually appear first at corners and along one elevation rather than evenly across a house.

What changes is that the maintenance is now unambiguously yours — and on Blackland clay that maintenance is both cheap and genuinely effective. Consistent perimeter moisture, drainage that moves water away from the slab, downspouts discharging well clear, and a plumbing test if anything seems off. Our Garland page sets out what that program actually looks like in practice.

Why a house this new moves at all

The soil is indifferent to how recently anything was built. Three mechanisms are specific to newer construction: fill placed during grading that is still consolidating, the moisture gradient that develops under any slab poured on clay as the ground works toward equilibrium across several years, and drainage that has not matured — backfill still settling around the slab, young planting, downspouts left discharging at the foundation.

None of that requires anyone to have done anything wrong. The mechanics, including why a modern slab tends to dish or crown rather than crack, are on the Cibolo page; the regional clay picture is on Dallas–Fort Worth.

One practical note that applies to effectively every house in this city: these are post-tension slabs. An absence of cracking is not evidence that nothing is happening — a post-tension slab is built to stay intact while the ground moves beneath it. The test is a survey, not a crack hunt.

Permits

The City of Frisco permits work inside its limits, which covers almost all of it. Frisco straddles the Collin and Denton county line, so the county on your appraisal record is not the permitting authority if you are inside the city — and you very likely are.

Foundation repair and underpinning normally require a permit with engineered documentation, and pulling it is the contractor's job. Plano, McKinney, Little Elm, Prosper and The Colony each run their own.

The first two rows are the ones to spend on first — on housing this new they frequently establish that nothing else is needed. General industry ranges, not quotes.

About these figures

Foundation Repair IQ does not quote prices and does not perform repairs. The figures below are general industry ranges published for orientation only — not quotes, not estimates for your property, and not binding on any contractor. Foundation pricing is set by the contractor after an on-site evaluation, and your actual cost may fall outside any range shown here.

Work General range Notes for a Frisco house
Elevation survey $300 – $800 Do it at year eight, while cover is still live
Engineer's evaluation $400 – $1,000 What a warranty claim actually needs
Concrete pressed pilings $300 – $600 each If you are paying yourself, on Blackland clay
Typical perimeter job $4,000 – $10,000 Commonly 8–20 support points
Steel push piers $1,200 – $1,900 each Deep clay or heavier two-story loads
Post-tension cable locating $300 – $900 Every house here has cables in the slab
Tunneling for interior piers $150 – $250 per linear ft Usually preferred over opening a post-tension slab
Downspout extensions and grading $300 – $1,500 The cheapest fix on a lot whose drainage is young
Hydrostatic plumbing test $250 – $600 A different cause, and possibly a different claim

Estimates for planning only. If your structural warranty is still live, the relevant figure may be none of these. See the cost guide and cost per pier.

General information, not legal advice

This page describes how Texas new-home structural warranties are commonly structured and what tends to change when one expires. It is not legal advice about your warranty, your contract or any remedy that may or may not remain available — the terms of your own agreement govern, and they vary. Read yours, and take the legal question to an attorney and the structural question to a Texas-licensed professional engineer.

Frisco foundation questions

Has my Frisco builder warranty expired?

Work it out rather than assume, because in this city the answer changed recently for an enormous number of households. Texas new-home warranties are commonly structured as one year on workmanship, two on major systems and ten on major structural components, with the foundation in that ten-year tier. Frisco went from roughly six thousand people in 1990 to over two hundred thousand by 2020, so the bulk of the housing was completed between about 2000 and 2020 — meaning a very large cohort crossed the ten-year line within the last few years. Two things to find: the date your warranty runs from, which the document itself specifies and is usually completion or closing rather than when you moved in, and who administers it, which is frequently a third-party company rather than your builder.

My house is eight years old. What should I do now?

Get an elevation survey, this year, while the warranty is still live. It costs $300 to $800 and takes about an hour, and it is the single highest-value thing available to you at that point on the clock. If it finds meaningful movement, you have time to notify the administrator and use a claim route that is about to close. If it finds nothing, you have a dated baseline for the rest of the house's life — and knowing what your floors measured in year eight is worth a great deal in year fifteen, when the question becomes whether something is new or has always been there. Almost nobody does this, because at year eight nothing appears to be wrong. That is exactly why it is worth doing.

My warranty just expired and now my floor is sloping. What are my options?

The warranty route is most likely closed, and we are not in a position to tell you whether anything else is open — whether any other avenue exists depends on your contract, the circumstances and the timing, and that is a question for an attorney rather than for a referral site or a repair contractor. What we can say is the practical part. Spend on measurement before you spend on piers: an elevation survey and an independent engineer evaluation together usually come to under $2,000, and in a fair number of cases on houses this new the engineer concludes the movement is within normal tolerance and no repair is needed. If repair is needed, you are now an ordinary homeowner on Blackland clay, and the cost per pier page covers how to read the quotes.

Is a Frisco house too new to have foundation problems?

No, and the soil is indifferent to how recently anything was built. Three things move newer houses specifically: fill placed during grading that is still consolidating, the moisture gradient that develops under any slab poured on clay as the ground beneath works toward equilibrium over several years, and drainage that has not matured — fresh backfill settling around the slab, young landscaping, downspouts left discharging at the foundation. None of those requires anyone to have done anything wrong. Our Cibolo page goes through the mechanics of new-construction movement, including edge lift and center lift, which is the usual presentation on a modern post-tension slab.

What does foundation repair cost in Frisco?

Blackland clay pricing: concrete pressed pilings commonly $300 to $600 each and a typical perimeter job roughly $4,000 to $10,000, with steel push piers at $1,200 to $1,900 where clay runs deep or loads are heavy. Essentially every house in Frisco is a post-tension slab, so add $300 to $900 for cable locating before any coring, and expect a contractor to prefer tunneling at $150 to $250 per linear foot over opening the floor to reach interior points. The numbers worth spending first, though, are the small ones — an elevation survey and an engineer evaluation, which between them establish whether you need any of the rest. General ranges only; see the cost guide.

Do I permit with Frisco, Collin County or Denton County?

With the City of Frisco for property inside the city limits, which is almost all of it. Frisco straddles the Collin and Denton county line, so the county on your appraisal record is not the permitting authority if you are inside the city — and most people are. Foundation repair and underpinning normally require a permit, typically supported by engineered documentation, and pulling it is the contractor responsibility. The neighboring cities each run their own: Plano, McKinney, Little Elm, Prosper and The Colony among them.
