San Marcos foundation work spans Old San Marcos historic stock, the major Discovery Hills and San Elijo Hills master-planned communities, Twin Oaks Valley rural-residential properties, and Cal State San Marcos-adjacent multi-family. Hillside settlement on San Elijo Hills and slab leak voids on aging Discovery Hills tract stock dominate..

What is the difference between this and a home inspection?
A general home inspection looks at 100 systems for 30 seconds each. A foundation inspection focuses entirely on the foundation, floor system, and structural envelope, with measurement and documentation that a general inspection does not produce. Many home inspectors recommend a follow-up foundation inspection when they see cracks or slope.
Will you tell me what is wrong even if you cannot fix it?
Yes. Some inspections find issues outside our scope: termite damage, dry rot, plumbing under-slab leaks, or seismic-retrofit needs. We will name them in the report and refer you to the right specialist.
