How Long Does Foundation Repair Take? 2026 Texas Guide

How long does foundation repair take is really two questions, and mixing them up is why the answers online range from one day to twelve weeks.

If you're worried about weeks of disruption, here's some good news. The crew is on your property for a short time. Most single-story slab jobs with outside piers wrap up in one day. What takes weeks is everything on either side of that: the engineer, the permit, the scheduling, and the plumbing test afterward.

By the end of this, you'll know how long each stage takes and which stage tends to slip. You'll also know why the answer is different in Mesquite and in Plano.

Permit lead time is the number that moved.

Across DFW in 2026, the wait between accepting a quote and a crew arriving averages 5 to 12 business days. It stretches in weeks of heavy rain, when demand spikes. That's faster than the national picture, where published permit windows run anywhere from 2 to 3 days in some counties to 2 to 3 weeks in others.

The other change worth planning around is that a plumbing test after the repair has become standard practice rather than an extra. Lifting a slab can break a line that was already under strain, so a test before and after is now normal on a well run job.

Put both together, and the realistic DFW window from first call to closing paperwork is about two to four weeks for a simple slab job.

In published industry figures, most homeowners get an inspection within 72 hours of calling.

The inspection itself is short. Someone measures floor heights through the house, looks at the slab edge and the drainage, and puts the findings in writing.

A written plan and estimate usually follow within 24 to 48 hours. It should set out the repair method, the scope, a projected timeline, and a price.

If you want a second opinion, a structural engineer's assessment adds 3 to 7 business days for the report and costs $300 to $800. On any Garland job that passes the permit threshold, you'll need an engineer anyway, so this is rarely wasted money.

Here's where the local answer really lives. National guides tend to stop at "requirements vary by jurisdiction."

They do vary. Here's how, across cities within about ten miles of each other.

• Garland requires a permit once the work is worth $2,000 or more. The fee is $45. You need an engineer's letter, a stamped pier diagram, and a foundation and elevation assessment plan before it's issued.
• Richardson starts at four or more piers. The permit must be approved and posted at the property before any work starts, and the contractor must already be registered with the city.
• Mesquite requires a permit for any foundation repair at all, at a flat $80, and wants one original engineer-sealed design plus two sealed copies.
• Plano runs a full plan review with two copies of construction documents.
• Wylie publishes a residential permit turnaround of 5 to 10 business days.
• Sachse wants three separately sealed documents: a pier layout plan, an engineer's letter, and pier specifications.
• Rockwall requires that any size addition to an existing foundation be designed and sealed by a Texas registered engineer.

Three of these carry scheduling traps that are easy to miss.

This is the part people expect to be long, and it usually isn't.

• Single-story slab, exterior piers only: about 1 day
• Two-story slab, or a job needing interior tunneling: 2 to 4 days
• Engineered drilled-pier projects: 3 to 7 days
• Minor crack sealing: a few hours

Weather is the main thing that moves these. Repairs can't be done in freezing temperatures or heavy rain, and rain turns the soil to mud and slows the digging. In North Texas, that's more of a spring problem than a winter one.

Interior piers take longer than exterior ones for a simple reason. Reaching them means either tunneling under the slab from outside or breaking through the floor inside, then putting everything back.

What the day itself looks like

For the common case, a single-story slab with exterior piers, the day usually goes something like this.

The crew arrives early and marks out the pier locations from the engineer's diagram. Any landscaping in the way comes out first, so anything you want saved is best moved before the day, not on it.

They then dig a hole at each marked point, down beside the slab edge to the depth the engineer specified. This is the noisy, messy part, and it takes most of the morning.

Pressed concrete piers go in next, driven down in sections until they reach refusal against a firm layer. Hydraulic jacks then lift the slab back toward level, a little at a time, while someone watches the floor heights inside the house.

The lift is the delicate stage. It happens gradually, because moving a slab too fast breaks things upstairs that weren't broken before.

Once the floor heights are where the engineer wants them, the piers are shimmed to hold that position. Then the holes are filled in and the ground is tidied up.

You can expect noise, a lot of dirt piled on your lawn, and limited access around whichever side is being worked on. Your water usually keeps running.

Three questions that move your date

These are worth asking when you get the quote, not afterward.

None of the three is an awkward question. A contractor who works in your city often will have all three answers ready. If they don't, it's fair to ask how often they work there.

This stage is where the cities differ most, and it's worth knowing before you plan around a date.

If your schedule depends on a sign-off date, it's worth asking early which of these applies. The difference between waiting on an engineer's letter and waiting on a city inspection slot can be a week.

The job isn't finished when the crew leaves, and this is the stage people skip.

Expect a settling period of 30 to 90 days while the house adjusts to its new position. Cosmetic work done before then tends to crack again.

So it's best not to repaint, re-tape drywall or re-grout tile straight away. Wait out the settling period, then fix what's still visible. The list is usually shorter than you feared.

A plumbing test after the repair belongs in this window too, because lifting a slab moves the lines underneath it.

Here are the usual causes of delay, most common first:

1. Permit and engineering. The published guides put this first, for good reason. It's the only stage measured in weeks.
2. Contractor backlog. Lead time in DFW runs 5 to 12 business days and stretches after heavy rain, because everyone calls at once.
3. The cause behind the movement. If a plumbing leak or termite damage caused the movement, that gets fixed first, and it's its own job with its own schedule.
4. Weather. Freezing temperatures and rain both stop work.
5. Access. Landscaping, patios and trees in the way all add hours.

Notice that only two of the five are about the repair itself.

One more that catches people out

It's worth booking the plumbing test before the repair, not just after.

A test before the repair records the condition of the lines going in. Without it, any leak found afterward turns into an argument about whether the lift caused it or whether it was already there. With it, there's nothing to argue about.

It adds little to the front of the schedule, and it can save weeks of dispute at the back of it.

If you take one thing from this: how long does foundation repair take is not a question about the crew. It's a question about the paperwork.

One day of digging, and two to four weeks of everything else. That ratio holds for almost every simple slab job in this area.

That means the most useful thing to ask a contractor isn't how fast their crew works. It's whether they're registered in your city, whether their engineer's drawings will be issued for construction rather than for pricing, and who signs the job off at the end. Those three answers predict your timeline better than anything else you can ask.
