House Leveling vs. Mobile Home Leveling in the Rio Grande Valley: Which One Do You Have?

September 21, 2026

Search for foundation help in Hidalgo County and the trade calls itself house leveling. The phrase covers two different jobs on two different kinds of home, and people call us for both. This post explains what each involves, why the ground under the Valley moves both of them, what each costs, and how to tell which one you have before anyone quotes you.

Two homes, two structures

A manufactured home is built on a steel chassis, two main I-beams running the length of each section, and sits on rows of concrete block piers with a cap and hardwood shims between the pier and the beam. It is held down by steel straps to ground anchors. Everything about how it is set is regulated by the Texas Department of Housing and Community Affairs under Occupations Code Chapter 1201 and the rules in 10 TAC Chapter 80, and the person doing the work has to hold a state installer’s licence, because section 1201.003(13) says installation includes “supporting, blocking, leveling, securing, anchoring.”

A pier-and-beam house is site-built. Wood sills or beams rest on concrete or masonry piers, floor joists run across the beams, and the floor deck sits on the joists. There is no chassis, no straps, and no state licence. Chapter 1201 does not reach it. The Valley’s older townsites, the streets laid out when McAllen, Mission, Pharr, San Juan, Alamo, and Donna were founded between 1904 and 1909, carry a lot of this housing, and it is what the local “house leveling” companies mostly work on.

The symptoms overlap almost completely: doors that stick, floors that slope, cracks over doorways, windows that bind. The fix does not.

What a manufactured home relevel involves

The crew shoots every pier with a water level off the most stable pier, so each one gets a number. Twenty-ton bottle jacks on solid cribbing lift the low sections a little at a time across several stations. Low piers are reshimmed or rebuilt. The state limits are specific: under 10 TAC 80.23, wedge shims go in from both sides of the I-beam, the shim stack may not exceed one inch, and the total wood on a pier including shims is capped at four inches nominal. A pier that needs more than that gets rebuilt at the right height on a footing sized to the soil. Then the whole frame is re-shot, the marriage line on a doublewide is checked, and the anchor straps are re-tensioned. A singlewide takes three to five hours; a doublewide six to eight. Full detail is on the mobile home leveling page.

What a pier-and-beam house relevel involves

The survey is of the floor, not a chassis: a level run across the deck room by room, and a crawl to map every pier, sill, and joist. Then the house is lifted at the beams on jacks, again in small increments, and the fix is whatever the crawl showed. Sometimes it is steel or hardwood shims between pier and sill. Often it is new concrete piers on proper footings where the old ones have sunk, leaned, or crumbled. Frequently it is a sistered joist beside one that has sagged or rotted, and occasionally a replaced beam. There is no shim limit to point at, so the check is whether the new piers are on footings and whether the beam is bearing on the pier rather than on a stack of scrap. The house leveling page walks through it.

We do not do slab foundation repair. A slab house that has cracked or tilted is a different trade with different tools, and anyone who tells you a pier-and-beam crew can fix a slab with a bottle jack is guessing.

The ground moves both of them

The reason both trades are busy here is under the floor. The USDA soil survey of Hidalgo County maps two kinds of ground.

On the uplands around Edinburg, north McAllen, and north Mission, the dominant soil is Hidalgo sandy clay loam, the most extensive series in the county at roughly 191,000 acres. It is well drained, with a low shrink-swell rating. Piers on it settle the way most people picture: a footing presses into ground that has been wet.

South of Business 83, in the old Rio Grande delta toward Pharr, Alamo, San Juan, Donna, and Weslaco, the map turns to Harlingen, Mercedes, Raymondville, and Runn clays. The NRCS description of Harlingen clay reads like a warning label: 60 to 75 percent clay, very slow permeability, slickensides starting 20 to 30 inches down, and “cracks remain open from 150 to 210 cumulative days in most years.” Raymondville clay loam cracks “3/4 inch to 2 inches wide” and “30 to 40 inches” deep when dry.

That ground swells when it is wet and shrinks when it is dry, and the Valley gives it both every year. The McAllen normals put annual rain at 24.17 inches with September the wettest month at 4.61, and the August high at 99.6 degrees. A wet fall pushes piers up on the side that got the water; a dry summer pulls them down. A house or a home on this clay moves in both directions across a year, doors stick in a different season than they did last year, and a doublewide’s marriage line opens and closes.

What a homeowner can do about clay

On clay, the honest mitigation is moisture control rather than a permanent fix. Keep the ground around the perimeter at an even moisture: a soaker hose run in the dry months so the clay at the edges does not shrink away faster than the clay in the middle, gutters and grading that keep a wet September’s water from pooling against one side, and a crawl that can breathe. It sounds too simple to matter. On Harlingen clay it is the difference between a relevel every few years and one every year.

What each costs

Both start with a free survey and a written price. The pricing page has the full tables and the cost calculator prices the manufactured home side.

Which one you have

Look at the outside. Skirting in vinyl or metal panels around a home that sits two to three feet off the ground, with a data plate inside a kitchen cabinet or closet and a HUD label on the exterior, is a manufactured home. A house with a crawl space behind a masonry or wood skirt, wood sills visible at the access door, and a floor that creaks along joist lines is pier-and-beam. If you are not sure, take a photo of the access opening and send it with the quote form; the answer takes ten seconds and it decides which crew comes out.

Who is allowed to do the work

On a manufactured home, Texas law is specific: only a licensed installer may block, level, or anchor it, and our installer licensing page explains how to verify a licence in one search. On a pier-and-beam house there is no state licence, which makes the questions simpler and more important: proof of current insurance, a written scope that names each pier and joist, and a survey you can read. Either way, the level check is free and the readings come in writing, whether or not you hire anyone.
