Why Early Diagnosis Matters

San Marcos sits on expansive clay soils. When clay dries during drought or stays wet during heavy rain (common near the San Marcos River), foundations shift. Small cracks widen. Floors tilt. Ignoring these signs leads to costly structural failure.

Catching problems early cuts repair costs and prevents safety risks. A hairline crack caught this year costs half what it costs when left for five years.

Common warning signs include stair-step cracks in exterior brick, sticky doors and windows, uneven or sagging floors, ceiling gaps, and water stains in crawl spaces. If you spot any of these in homes near Blanco River Village or Southwest Hills, contact a professional for a free inspection.

We perform detailed inspections using visual surveys and diagnostic tools to measure settlement and identify water sources. Once we know the cause, repair solutions are straightforward and backed by warranty.

Frequently Asked Questions

How do I know if my home needs foundation repair?

Look for stair-step cracks in exterior walls, sticking doors and windows, uneven floors, ceiling gaps, or water in the crawl space. A free professional inspection confirms whether repair is needed.

How long does foundation repair take?

Most residential foundation repairs complete in one to two weeks. Crawl space encapsulation may take 3–5 days. Commercial projects depend on scope and building complexity.

Do you handle historic home repairs in the Dunbar neighborhood?

Yes. We manage repairs in historic districts and coordinate with preservation guidelines and city permits required for Dunbar, downtown, and other protected areas.

Why do San Marcos homes have foundation problems?

Clay-rich soils expand when wet and shrink when dry. Proximity to the San Marcos River, drainage issues, and aging foundations all contribute to settling and cracking common in the area.

We provide industry-leading warranties: Lifetime Warranty on slab foundation repairs and 10-year warranties on pier-and-beam repairs. Crawl space encapsulation carries a 25-year warranty.
