Why houses move in Lubbock

Lubbock soils hold clay that swells when wet and shrinks when dry, with a hard caliche layer a few feet down. Rain comes in heavy bursts after long dry spells, and the city drains to playa lakes. That mix moves both the older pier-and-beam homes near Texas Tech and the newer slab homes in south Lubbock.

  • Lots of new homes

    Wolfforth grew about 30 percent from 2020 to 2023, according to Census estimates, and far south Lubbock is full of homes built in the last ten years or so. New slabs go through their early settling years now.

  • Clay keeps moving

    USDA soil surveys show a clay subsoil under common Lubbock area soils. Clay swells and shrinks with water, so a house here never fully stops moving with the seasons.

  • Record drought

    Lubbock got only 5.86 inches of rain in 2011, the driest year on record, compared with a normal of about 18.6 inches, according to the National Weather Service. Dry years like that pull soil away from foundations.

What settling looks like

Every house settles a little. The ground under it firms up, the wood frame dries and shrinks, and small cracks show up. That is not always a problem. The question is whether it stopped.

Common things people call "settling":

Hairline cracks in drywall

Often at a seam or over a door.

Thin cracks in the garage floor

Or a patio slab.

Nail pops

In the ceiling or walls.

A small gap

Where trim meets the wall.

Soil pulling away

From the foundation in a hot, dry month.

A door

That needs a slight adjustment after the first year.

Settling or moving?

Here is the difference that matters. Settling slows down and stops. Foundation movement keeps going, or comes back every year.

Probably normal settling:

  • The cracks are thin, like a hair, and have not changed in a year.
  • They showed up in the first few years after the house was built.
  • Doors and windows still open and close fine.
  • Floors feel flat.

Probably foundation movement:

  • A crack keeps getting longer or wider.
  • A crack is wider than about a quarter inch.
  • One side of a crack sits higher than the other.
  • Doors that worked fine now stick or will not latch.
  • Floors slope, or a marble rolls to one side.
  • Stair-step cracks show up in the brick outside.
  • Cracks open in summer and close in winter, every year.

Why houses settle in Lubbock

New homes. Much of Lubbock's growth is new construction on the south and west sides. Far south Lubbock has many homes built in the last ten years or so. Wolfforth grew about 30 percent from 2020 to 2023, according to Census estimates. In the first years after a slab is poured, the soil under it firms up, and a new lawn and sprinkler system change how wet the ground is. A few small cracks in that time are common.

Clay that never quite stops. USDA soil surveys show that common soils around Lubbock have a clay subsoil. Clay swells when wet and shrinks when dry. Unlike sand, it does not settle once and stay put. A house on clay keeps riding up and down a little with the seasons. That is why an older house can show new cracks decades after it was built.

Dry years. Lubbock averages about 18.6 inches of rain a year, according to the National Weather Service. In 2011 it got only 5.86 inches, the driest year on record. In a stretch like that, the clay shrinks deep under the house, and the soil around the edge pulls away from the slab. Edges can drop while the middle stays put.

Playa ground. Lubbock drains to playa lakes. USDA says the soil on playa floors is 50 to 60 percent clay and cracks up to 40 inches deep when dry. Homes on or near low ground can settle more.

The soil gap in summer

In a hot, dry summer, the soil can pull away from the slab. A thin gap that closes after rain is common. A wide gap that stays open is a sign the soil under the edge of the house is drying out too.

Keeping the soil around the house evenly moist can help in a long drought. The City of Lubbock lets you hand water any day of the week. Lawn irrigation is limited to two assigned days based on your address, according to the city's 2026 guidelines, so check the current rules before you set a schedule. Keep water a little away from the wall, and never let it pool.

What the fix usually is

The inspector takes floor level readings across the whole house and maps the cracks. This tells you if the house is settling normally or if one part is moving.

If it is normal settling, cracks can be sealed and drywall patched. Fix any drainage problem so it stays that way.

If one part of the house is still dropping, the usual fix is piers under that section, set down to firm ground. The house is lifted back toward level and held there.

If water is the cause, gutters, grading or a leak need to be fixed along with any piers.

What it costs

These are typical ranges from published cost guides, not quotes. If it is normal settling, there may be nothing to pay for beyond a patch. Your price comes in writing after the free inspection.

Before the inspection

  1. Find your build date and any builder warranty papers.
  2. Photo each crack with a coin for scale and write the date on the wall in pencil.
  3. Check again after a big rain and after a dry spell.
  4. Note any doors that changed.
  5. Look at the soil around the house for gaps or standing water.

Frequently asked questions

How long does a new house settle?

Most of the early settling happens in the first few years, as soil packed during building firms up and the new lawn and sprinklers change how wet the ground is. Small hairline cracks in that time are common. Cracks that keep growing after that are worth a look.

Is it normal for a house to keep settling after 20 years?

An older house should be mostly done settling. On clay soil, though, it can keep moving up and down with wet and dry years. New cracks in an older house usually mean something changed, like a leak, a new sprinkler zone or a long drought.

Why is there a gap between the soil and my foundation?

In a dry spell, clay soil shrinks and pulls away from the slab edge. A thin gap that closes after rain is common. A wide gap that stays open for months means the soil under the edge of the house is drying out too.

Should I water my foundation in Lubbock?

Keeping the soil around the house evenly moist can help in a long drought. The City of Lubbock allows hand watering any day of the week. Check the city's current irrigation rules before you set up a sprinkler or hose schedule, and never let water pool against the wall.

Does a settling crack mean my house is not safe?

Most settling cracks are not a safety problem. A crack that grows, a door that suddenly will not open, or a floor that drops quickly should be looked at soon.

My builder's warranty is ending. Should I get an inspection now?

It is a good time. An inspection gives you a dated record of floor levels and cracks while the builder may still be on the hook.
