What a foundation inspection measures, and what to expect.

A foundation inspection should end with measurements. This is the walkthrough, stop by stop: the floor-elevation survey that shows how far and where the slab has moved, the crack mapping and drainage review, and the written report you keep. Roughly a third of the time the read is “monitor it, water the foundation, fix the gutters,” and we say so. Ready to have one done? Book your free foundation inspection.

What actually happens

What actually happens at your inspection.

STOP 01

Exterior walk

Brick and mortar joints, frieze boards, caulk lines, expansion joints, corners. We photograph and measure every crack (width, direction, location) because the pattern tells us which way the slab is moving.

STOP 02

Interior observations

Doors and windows (which stick, which corners), drywall cracks above openings, tile and flooring, baseboards pulling from floors. You walk with us, because we want you seeing what we see.

STOP 03 · THE HEART OF IT

Floor elevation survey

A ZipLevel altimeter reads relative floor heights across the whole slab, on a grid. This is the heart of the inspection: feelings lie, slopes mislead, but a 40-point elevation map doesn't.

STOP 04

Moisture context

Drainage paths, gutters and downspouts, grading, trees within root-reach of the slab, irrigation, and plumbing red flags (unexplained warm spots, high bills, constantly damp soil).

STOP 05

The straight answer

Same visit, you get the picture in plain English: stable, monitor, or repair, with the elevation map to justify it. If repair makes sense, you get a marked pier plan and a firm price. If not, you get advice and we leave.

What’s included

Every free inspection includes all five.

Floor elevation readings

A ZipLevel altimeter maps relative floor heights across the whole slab on a grid, and it is the objective heart of the inspection.

Crack mapping with photos

Every crack documented: width, direction, location, inside and out. The pattern tells us which way the structure is moving.

Drainage & moisture review

Gutters, downspouts, grading, trees within root-reach, irrigation, and plumbing red flags, which are the causes behind most movement.

Doors, windows & interior checks

Which doors stick, which corners rack, what the trim and tile are saying, all read against the elevation map, not in isolation.

Written findings

The elevation map, crack documentation, our read on cause and trajectory, and a recommendation, including “no repair needed” when that's the truth.

Costs

Free inspection vs. paid engineer report, both are legitimate.

Motmot inspection, free

Elevation survey, crack mapping, drainage review, written findings, and a firm per-pier price if repair makes sense. The honest caveat about any contractor inspection, ours included, is the incentive. The inspector works for a repair company. We blunt that by paying nobody a commission on pier count and putting the elevation map, not a pitch, at the center of the visit.

Independent structural engineer, typically $300–$600 in Texas

A licensed P.E. sells you nothing but the report, and that independence is worth paying for in the right cases: pre-purchase due diligence on a big unknown, litigation or insurance documentation, unusual structures, or a tiebreaker between wildly different repair bids. We work alongside independent engineers comfortably, and we’ll tell you when your case warrants one.

From real inspections

What we photograph and measure.

Every crack gets documented (width, direction, location) because the pattern, read against the elevation map, is what separates cosmetic from structural. Want to pre-read your own walls? Start with how to tell if foundation cracks are serious and the top 10 signs, ranked.

Interior crack from a window corner. Diagonal cracks running off door and window corners are the interior half of the story. We map them against the elevation survey before drawing any conclusion.

The elevation map

The elevation survey puts your floor into numbers.

Every inspection produces a relative elevation map like this one. Green is level; red is the low corner. The pattern, not any single number, reveals whether movement is settlement, heave, or nothing at all.

It also becomes your baseline. If we recommend monitoring, the next survey (also free) shows exactly what changed. If we repair, the before/after maps document the lift for your records and for your future buyer’s inspector. (Buying rather than owning? Here’s our option-period playbook for foundation inspections, plus the ten questions to ask any contractor, including us.)

From a Google review

“The inspection process was thorough, including interior and exterior evaluation and elevation readings, and everything was clearly explained so we understood the issue and the solution.”

Straight answers

Inspection questions, answered straight.

Expect a walkthrough of your home inside and out that takes about 60–90 minutes. A Motmot inspector runs a floor-elevation survey to measure how far and where the slab has moved, maps and photographs cracks, reviews drainage and grading around the foundation, and checks doors and windows for racking, then hands you a written summary with the cause, the trajectory, and a recommendation, including “no repair needed yet” when that's the truth. It's yours to keep regardless of what you decide.
Motmot Foundation Repair is a family-owned, inspection-first company serving San Antonio and Central Texas from our San Antonio shop, with a 5.0-star Google rating. The inspection is free, run by an ICC-certified, inspector-led crew, and produces a written elevation report. And because roughly a third of our visits end with “no repair needed yet,” you get a measurement to work from.
For a pre-purchase foundation assessment in San Antonio or Central Texas, contact Motmot Foundation Repair at (210) 816-0034 for a free elevation survey and written report you can take into negotiation. We flag anything that should affect the price and tell you what a repair would actually cost. See our guide to a foundation inspection before buying a house.
Usually 60–90 minutes for a typical home: about half outside, half inside, and the elevation survey throughout. Larger or complex homes can run longer.
For most perimeter settlement, a measured repair plan is standard practice and an engineer is optional. We'll tell you plainly when your case does warrant one, like unusual structures, severe interior movement, new construction disputes, or documentation for litigation. We work alongside independent engineers comfortably.

Look it up yourself

Your inspection starts with your specific soil.

The USDA’s Web Soil Survey maps the exact soil under any address in the country, giving you the series name, its shrink–swell rating, drainage class, and depth to bedrock, free and public.

How we use it: before we ever name a method, we read what’s actually beneath your slab, then confirm it with elevation readings on site. You can pull your own map too. Enter your address, draw a box around your lot, and open “Soil Data Explorer.”
