Whether a crew can get under the house belongs at the top of the call script
Access decides the method, the price and the length of the job, and a shop that finds out on arrival has already lost the margin.
A raised house with clear pier and beam access is a different job from the same repair under a slab, and both are different again from a raised house with a closed skirt, stored belongings underneath or standing water from poor drainage. Asking early changes what you quote and what you send.
Put the questions in order and keep them short. Parish and address, raised or slab, approximate year built, whether anything blocks access underneath, where the water is, and whether it is shut off. Six questions, asked the same way every time, by whoever answers.
Write it down so it survives staff changes. Most intake improvement is not clever, it is consistent. The shop that asks the same six questions on every call can compare calls; the shop that improvises cannot.
Then use the answers. If the year built and the access notes are visible on the dispatch board, the truck arrives stocked for the job rather than making a second trip, and second trips are where a profitable job becomes a break even one.
