Foundation Repair in Pflugerville, TX

Facts About Pflugerville and Foundation Repair

The middle Pflugerville house went up in 2004, which decides which repair fits it

The Census puts the median year built in Pflugerville at 2004, so this describes a great many houses here.

Age matters because it decides what is under the house. Post-tension slabs — concrete pulled tight by steel cables after the pour — became the common residential method through the 1980s and 1990s. Before that a slab was conventionally reinforced with rebar, or the house sat on pier and beam with a crawl space under it. Those three take different repairs, and a contractor who has not established which one you have is quoting a method rather than a job.

Ask which it is before anyone prices anything, and ask how they know. On a post-tension slab the cable layout has to be located before a single hole is cut, because cutting a live cable is a much larger problem than the one being fixed.

99 percent of Pflugerville sits on soil that sheds water instead of taking it

The USDA sorts soil into four groups by how fast water moves down through it. Group A is sand and drains freely; group D holds water at the surface. Measured against the city limits, 99 percent of Pflugerville is group C or D.

On a drainage site that figure is about where water goes. On a foundation it is about how long the soil stays wet, and therefore how far it swells. Ground that sheds takes on water at the top and holds it there, so the moisture change that moves a slab is concentrated in the first few feet — exactly the depth a shallow footing bears on.

It is also why the same house can be stable for years and then move. Nothing about the soil changed. The pattern of water reaching it did: a new patio, a regraded flowerbed, a downspout that came loose, a drought followed by a wet spring.

Pflugerville foundations are worked by the swing between wet and dry, and 6.53 inches is the wet end

The National Weather Service publishes what a storm drops here. In Pflugerville a ten-year storm delivers 6.53 inches of rain in twenty-four hours.

The number matters to a foundation for a reason that is not obvious: it is one end of the range the soil moves through. A clay soil that takes on that much water swells; the same soil at the end of a dry summer has shrunk. The distance between those two states is the distance the ground under a footing travels, and a house does not travel evenly — the shaded side and the side under a tree do not dry at the same rate as the side facing the afternoon sun.

That is why differential movement, not total movement, is what cracks walls. Ask what a proposed repair does about the difference between one side of the house and the other, not just about the corner that has already dropped.

What moves a foundation here is the soil changing size, not the house changing weight

Surface clay runs as high as 54 percent in Pflugerville

Clay is the fraction of soil made of the finest particles, and it is the fraction that holds water. Soil with this much of it swells when it takes water on and shrinks when it dries, every year. That cycle is the mechanism behind almost every foundation complaint in this city, which is why the first question about a crack is when it appears rather than how wide it is.

The age of the house decides which repair is even available

The median year built in Pflugerville is 2004

Post-tension slabs, conventionally reinforced slabs and pier-and-beam construction take different repairs, and which one a house has is a function of when it went up. On a post-tension slab the cable layout has to be located before anything is cut. Ask which construction you have, and ask how they established it.

How foundation repair works

Foundation repair is the business of putting support under a house that has lost it. A pier is driven or drilled down to ground that does not move, the structure above is lifted back toward where it started, and the load is transferred onto the new support. The house is not made new. It is made stable.

Three things decide the price, and none of them is the size of the house. How many support points it needs. How many of those are indoors, because an interior point means opening the floor and closing it again. And how deep each one has to go before it reaches competent ground, which is measured during installation rather than assumed beforehand.

Doors and windows that stick

A door that catches at the top corner, a window that will not close square, or a gap that opens along the top of a frame. These are the frame telling you the opening is no longer rectangular. Before booking anything, get relative floor elevations measured across the whole house — a survey costs a fraction of a repair and is the only thing that says whether the movement is 1 inch or 3, and whether it is still going.

Cracks in brick, drywall or the slab

A stair-step crack through brick mortar, a diagonal crack from a door corner, or a line across a slab. Width is the wrong single test: a hairline crack that is growing matters more than a wider one that has been still for a decade. A dated photograph with a ruler in it, taken a few months apart, costs nothing and answers the only question that decides whether to repair or to watch.

Which foundation repair method fits a Pflugerville house

Foundation Inspection and Elevation Survey. A foundation inspection takes relative floor elevations across the whole structure and writes them down, so the shape and size of the movement is a measurement rather than a description. Foundation Inspection and Elevation Survey in Pflugerville, TX.

Foundation and Wall Crack Repair. Cracks are repaired once movement has stopped. Sealing one that is still opening buys a season and removes the only thing telling you how fast the house is moving. Foundation and Wall Crack Repair in Pflugerville, TX.

House Leveling and Foundation Piers. Leveling a house means installing support below the soil that is moving, then raising the structure back toward its original elevation as far as it will safely go. House Leveling and Foundation Piers in Pflugerville, TX.

Concrete Leveling and Slab Lifting. Concrete leveling raises a sunken slab by filling the void underneath it, either with a cement slurry or with expanding foam, and the concrete itself is reused. Concrete Leveling and Slab Lifting in Pflugerville, TX.

Pier and Beam Repair. Pier and beam houses are leveled by adjusting the supports under the floor framing, which is far cheaper than slab work when the piers themselves are sound. Pier and Beam Repair in Pflugerville, TX.

Foundation Drainage and Moisture Control. Clay swells when it takes on water and shrinks when it dries, so the damage comes from the swing between the two rather than from water alone. Foundation Drainage and Moisture Control in Pflugerville, TX.

Commercial Foundation Repair. Commercial foundation work is priced from occupancy, phasing and engineered load before it is priced from area, because the building usually has to keep operating. Commercial Foundation Repair in Pflugerville, TX.

Crawl Space Repair. Crawl space repair covers three separate jobs — sealing the ground so moisture stops rising, supporting the framing so the floor stops moving, and getting water out and air through. Most houses need one of the three, not all of them. Crawl Space Repair in Pflugerville, TX.

Choosing between two of them

Questions Pflugerville homeowners ask about foundation repair

Most of what decides a foundation repair job is decided by the ground under one particular house, which is why a general answer is only ever half of one. The questions below are answered here twice over: what the general answer is, and what it means on Pflugerville ground. Foundation Repair Questions — Pflugerville, TX.

When you do not need foundation repair

Two things get mistaken for foundation failure more than anything else. A hairline crack in mortar or brick veneer that has been there for years and has not widened is a finish crack, not a structural one. And a door that binds in late summer and swings free after a wet winter is following the season: clay soil swells when it takes on water and shrinks when it dries, and the house moves a little with it. Neither one is a reason to put piers under a house, and a contractor who quotes on either without measuring first is selling you the wrong job.

Two checks worth making before anyone quotes you.

• Date the crack. Mark both ends with a pencil, write the date on the wall beside it, and measure the width against something known — a dime is about a sixteenth of an inch. Look again in three months. A crack that has not moved is not an active one, and no pier will make it narrower.
• Watch one door through a season change. A door that sticks in the dry months and clears after a long wet spell is tracking the weather, not a failing foundation. A door that has bound a little harder every season for two years is the one worth an inspection, and it is the pattern to describe when you call.

If both checks come back quiet, wait a season and look again before spending anything larger.
