Allen, TX · Collin County
Foundation Repair in Allen
Allen is a newer city, with most homes built since the nineties on post-tensioned slabs and many still under a builder warranty. Foundation questions here start with the warranty and a clear set of measurements.
01 — The area
Foundations in Allen
Allen lies north of Plano in Collin County, and most of what's built there went up in the last thirty years. Large master-planned neighborhoods, newer schools and plenty of two-story houses define the city, and the typical home is on a post-tensioned slab on graded, relatively young lots.
That profile changes the foundation conversation. Many houses are still within the period covered by a builder's structural warranty, which can make a difference to who pays for a repair. And because the neighborhoods are newer, the first serious wet-dry cycles are still happening to many of them.
The soil is the Collin County clay that underlies Plano and most of the surrounding cities. It behaves the same way: swelling in wet years and shrinking in dry ones, with the greatest effect at the edges of the house.

Start with the builder's warranty
Many Allen homes came with a structural warranty from the builder or from a third-party warranty company, commonly lasting several years for major structural defects. The terms vary, and definitions of what counts as a defect are specific. Before paying for a repair, find your closing documents and read the warranty carefully, including the deadlines to file a claim.
An independent inspection is still useful if you plan to file a claim. It gives you your own elevation readings and an outside opinion, so you aren't relying only on the builder's assessment.

Post-tensioned slabs on young lots
Post-tensioned slabs are the standard here. They handle movement better than older conventional slabs, but they still respond to uneven moisture, and young lots have particular issues: soil that was graded during construction, landscaping that was added later and drainage that may not have settled into its final pattern.
When one side of such a slab drops, the repair needs care. Cables must be located before any digging or coring, and the pier plan has to avoid them.

Drainage in compact neighborhoods
Homes in Allen's newer subdivisions often sit close together on small lots, so side yards are narrow and drainage runs through shared swales. A blocked swale, a fence that holds water or a downspout that empties near the slab is a common cause of one side of the house staying wet.
Check your homeowners association's rules before changing grading or adding visible drains. Often a modest fix, like extending downspouts and clearing a swale, is enough.
05 — Allen
Landscaping and irrigation
New owners often add patios, outdoor kitchens and beds, and install irrigation. Each changes how water moves around the house. Irrigation heads that spray the foundation wall can keep the soil too wet, while beds with mulch higher than the slab can trap water.
A walk around the house during an irrigation cycle is a simple test. Water should fall on the lawn and plants, not the slab edge.

Buying a newer home in Allen
Even a house that's only a few years old can be inspected. If the general inspector noted cracks or movement, elevation readings clarify whether it's cosmetic. Buyers of homes still under warranty should find out how to make a claim and which deadlines apply.

How we approach newer homes
A newer house deserves a different kind of inspection from a fifty-year-old one. The technician is looking less for evidence of decades of movement and more for the early signs of a lot that hasn't settled: new cracks, new sticking doors and the water patterns that are likely to cause them. Elevation readings taken early are valuable precisely because they give you a reference for later.
When a house is still under warranty, the findings are written in a way that helps a claim: where the readings are high and low, what the cracks look like and what the drainage is doing.

Moving in, landscaping and the first dry summer
The first long, dry summer in a new house is when many owners see their first cracks. Soil that was disturbed during construction dries and shrinks faster than undisturbed ground, and the edges of the slab respond. A soaker hose a foot or two from the foundation, run during dry spells, keeps the soil from pulling away.
If you're installing landscaping, keep trees well away from the slab, keep the soil level below the top of the slab and make sure the irrigation system doesn't soak the foundation.

Questions
Allen — asked and answered
My Allen home is only a few years old and has cracks. Is that normal?
Some cracking is normal as a new house settles. A pattern of cracks and sticking doors is worth checking, and your builder warranty may apply.
Should I call the builder or a foundation company first?
Check your warranty terms and deadlines. An independent inspection can document the readings before you file a claim.
Can my irrigation system cause foundation problems?
Yes, if it soaks one side of the house or leaves another dry. Adjusting zones is inexpensive.
How are post-tensioned slabs repaired?
With piers placed after the cables are located. The plan is designed around them.
Is the inspection free?
Yes, the repair company's inspection and written estimate are free and carry no obligation.
