Diagnosis First

What is prompting the look under your house?

Different triggers deserve different urgency. Pick the reason you are considering an inspection and see how quickly it should happen.

Years since anyone entered the crawl spaceNo symptoms, just due for a look

A baseline inspection with no symptoms is the cheapest one you will ever schedule, because whatever it finds is at its earliest stage. You get documented conditions and elevation numbers to compare against in the future.

Odor after rain, humidity, no structural symptoms yetMusty smell or dampness upstairs

Odor is usually the first messenger of a moisture problem still in its inexpensive phase. The inspection traces the smell to its source and route, which is the difference between a targeted drainage fix and years of air freshener.

Visible or feelable floor change, doors stickingFloors sagging, bouncing, or sloping

Floor symptoms mean the support system is already involved, and the inspection becomes the first step of a repair: probe tests, plumb checks, and an elevation survey that defines exactly what failed and what it will take to fix.

A specific event or transaction needs answers nowAfter a flood, quake, or during a sale

Events that can move or soak a foundation deserve prompt documentation, and a transaction deserves it in writing. The inspection delivers a dated, written record of conditions, which protects you whichever way the findings go.

Watch

Crawl Space Inspection: see how we actually do it.

Almost nobody goes into their own crawl space, which is reasonable, and also why problems down there get years of free rein. The space under your floors holds the posts, pads, and girders carrying your home, the plumbing that serves it, and the soil conditions that decide whether all of that stays sound. A crawl space inspection is how you find out what is actually happening down there without crawling through it yourself, and it is the first step of every repair we perform, because we do not recommend work we have not measured.

CH 01

How Often Should a Crawl Space Be Inspected?

Crawl space problems share one advantage over you: privacy. Rot, standing water, leaning posts, and pest damage all do their early work in a space the household never enters, and by the time evidence reaches the living space as a dip or a smell, the cheap phase of the repair is usually over. An inspection trades a little scheduled attention for years of expensive surprise.

The trigger list of crawl space warning signs is short: symptoms upstairs such as sagging or bouncy floors or a persistent musty smell, a flood or major storm season, an earthquake, a purchase or sale of a raised foundation home, or simply the fact that nobody has looked in years.

CH 02

What the specialist documents under the house

The under house pass is systematic, not a flashlight sweep. Every post gets a probe test at its base, because rot starts inside the wood where eyes cannot see it. Every support gets a plumb check, every pad gets examined for cracks, tilt, and the shim stacks that mark where someone chased a problem before. Girders and joists are checked for sag, moisture staining, and pest damage. Plumbing runs are checked for the slow leaks that keep one patch of soil wet through summer.

Moisture gets traced rather than just noted: damp soil, condensation on pipes and ducts, staining on framing, and any pooled water each point back to a route, and naming the route is what turns a finding into a fix. The full route map lives on our moisture problem page.

CH 03

The measurement you cannot do by eye: floor elevations

The eye is a terrible level. A floor can be an inch out across a room and read as flat, or perfectly level and feel sloped because a doorway is racked. The elevation survey settles it with numbers: readings across the floor plan map exactly how the home sits, where it is low, by how much, and whether the low spots line up with the supports flagged below.

The survey is also your baseline. A second survey a year later turns the question is it moving into a measured answer, which is the difference between monitoring and guessing.

CH 04

What comes back to you: the written report

Everything found under the house lands in a written report in plain language: what we found, what it means, what to watch, and what, if anything, to fix, with real costs attached. Healthy crawl spaces get reports that say exactly that, and plenty of them do. Findings that warrant repair come with the reasoning laid out, from a single post replacement to a full plan pairing post and girder repair with the drainage correction that protects it.

The report is yours whether or not we ever do a dollar of work under your house. That is not a sales posture; it is how measurement first companies stay honest, because a written finding can be checked by anyone you hand it to.

CH 05

When the Inspection Finds Nothing Wrong

A meaningful share of inspections end with no repair recommended, and that outcome is worth as much as any fix. You get documentation that the supports are sound, the moisture is within normal, and the elevations are level within ordinary tolerance, plus a baseline for every future comparison. For a purchase or sale, that document answers questions before they are asked.

If something is developing but not yet actionable, the report says monitor, names what to watch, and puts a number on when to look again. Watching is a legitimate outcome; being sold something is not the price of a look.

Regional Context

Why crawl spaces sag in California, Arizona, and Nevada homes

Raised-foundation homes across our service area rely on a grid of posts and pads in the crawl space. Seasonal soil movement works those supports loose, moisture softens the pads they bear on, and the floors above start to bounce and slope. The repair is structural: restore solid, adjustable support under the floor system rather than masking the symptoms.
