Grand Prairie's housing spans roughly eighty years of construction, which means we work on both major residential foundation types almost every week. The repair approaches share a goal and share almost nothing else.
How to tell which one you have
If your home has a crawl space, floor vents around the exterior, and the floor sits noticeably above grade, it is pier and beam. If the floor is at grade and you have no crawl space access, it is a slab. Most Grand Prairie homes built after about 1960 are slab; older neighborhoods near Dalworth and the original downtown grid have plenty of pier and beam.
How slabs fail
A concrete slab is a single rigid plate. When clay soil under one section shrinks in a dry summer, that section loses support and the plate flexes or cracks. Symptoms show up in brittle finishes first — brick, drywall, tile — because the concrete transfers stress everywhere at once.
How slabs are repaired
Piers are driven along the perimeter, and sometimes through the interior, until they reach soil that does not move seasonally. Hydraulic rams then lift the slab in small synchronized increments back toward original elevation. It is outside work, usually one to three days, and you can stay in the house.
How pier and beam fails
Pier and beam is a wood structure on discrete supports, so it fails locally. A single rotted girder, a pad that sank, or a shim that fell out produces a sag in one room. Add a damp crawl space and the wood problem compounds itself over years.
How pier and beam is repaired
Crews work in the crawl space, jacking girders gradually while setting new concrete pads and shims, replacing rotted wood, and often adding interior supports that the original build never included. Moisture control almost always accompanies the structural work.
Cost and disruption compared
- Simple releveling: pier and beam is usually less expensive than slab piering
- Extensive wood replacement: pier and beam can exceed a comparable slab job
- Timeline: slab one to three days; pier and beam one to two days plus wood repair time
- Future adjustability: pier and beam can be re-shimmed cheaply; slabs cannot
- Access to plumbing: far easier and cheaper under pier and beam
Which is 'better' to own in North Texas?
Neither is inherently better. A well-drained slab on stable soil can go decades untouched. A pier and beam home with a dry crawl space and adequate pads is easy and cheap to maintain. What determines outcomes here is water management, and that is true for both.
