Foundation Inspection Before Buying a House

Q: Who pays for the pre-purchase foundation inspection?

Ours is free either way, so the better question is who orders it — and that should be you, not the seller. An inspection commissioned by your side answers to your interests, and you keep the elevation map regardless of how the deal goes.

Q: The seller's inspector says 'monitor.' Is that bad?

'Monitor' is a legitimate verdict — most Central Texas slabs move a little and stabilize. What you want is the baseline that makes monitoring meaningful: a dated elevation map. Without numbers, 'monitor' just means 'nobody measured.'

Foundation Inspection Before Buying a House: A Central Texas Buyer's Guide

The 20-minute check any buyer can do at a showing — and the one professional step (highlighted) that turns guesses into numbers.

Foundation anxiety kills more Central Texas deals than foundation problems do. Buyers see a disclosure mention, picture catastrophe, and walk — sometimes away from the best-protected house on the street. Sellers hide history they should be advertising. Both sides negotiate on vibes when numbers are cheap to get. Here's the calmer playbook.

First, reframe: "repaired" can be a green flag

On corridor clay, a 20-year-old house that has never moved is the unusual one. What separates good buys from bad ones isn't the presence of history — it's the quality of the paper trail:

Green flags: a pier map with depths, before/after elevation surveys, a transferable lifetime warranty from a company that still answers its phone, and receipts for any related plumbing or drainage work.
Yellow flags: "previous repair" with no documents, a warranty from a defunct company, or repair on one side with fresh symptoms on another.
Red flags: fresh paint over patched diagonal cracks, doors that have been recently planed (look at the top edge), new caulk in stair-step mortar lines right before listing. None are proof of deception — together they're a pattern worth measuring.

The 20-minute showing check

Use the checklist above at any serious showing. None of it requires tools beyond your phone: photograph everything, note which doors rub and where, and roll a marble or use a level app near exterior corners. You're not diagnosing — you're collecting the question list for the professionals.

Then spend the option period wisely

A general home inspector will note symptoms; what they typically can't give you is the number that matters: how far out of level is the slab, and where? That's a floor elevation survey — about an hour on site, free from us, and it converts the entire negotiation from adjectives to inches.

Negotiation math: if the survey shows a corner needing 6 piers, that's a knowable cost (see our cost guide) — ask for exactly that, not a fear-based discount. If it shows a stable slab, you just bought confidence for free. Either way you keep the elevation map as your day-one baseline.
