A good place to start

Water pooling under house

Water pooling under a house can call for plumbing, drainage or water-entry investigation. What you have noticed about rain, water use and visible leaks helps narrow the starting point. Choose observations you already have below, then compare local businesses. Do not enter an unsafe space to answer these questions.

    The aim is to find someone to investigate, without guessing a repair.

    01

    Describe your job
    03

    You can see a leak or overflow

    Describe the pipe, tap or drain from a safe place. There is no need to get closer for this form.

    Describe your job

    Help the business understand what is happening

    Describe where the water appears, when you first noticed it and whether it changes with rain or normal water use. Include photos taken from somewhere safe. You do not need to open walls, climb onto the roof or reproduce a leak to complete this form.

    The questions narrow possible trades; they cannot establish the cause remotely. Ask the business whether it investigates this kind of problem, what an assessment involves and whether a visit has a fee. Agree the investigation and repair scope before work starts.

    If the property is rented or part of a strata scheme, contact the property manager or owners corporation about access and responsibility. Water can travel away from its source, so the first visible patch is not necessarily where the repair belongs.

    Choose who you want to ask

    The businesses below your answers come from Yamate’s live directory. A category match does not verify that a business handles every possible cause. Read its details and confirm the relevant work, address and any required licence before booking.

    Select the businesses you want to contact and review one request. Your observations and suburb are included automatically. You can change an answer before sending; changing the job clears the previous selection so it does not go to the wrong recipients.

    Good questions. Plain answers.

    Does water under the house mean a pipe is leaking?

    Not necessarily. Plumbing leaks and water entering from outside require different investigations. Describe the timing and observations; a business needs to establish the source.

    Can I use this without going under the house?

    Yes. Use what you already know and choose Not sure for anything you cannot safely see. Do not enter an unsafe space or go near water and electrical equipment.

    Why do several trades still appear?

    Some observations do not establish a single starting point. The page keeps relevant categories available so you can ask about an assessment instead of treating an uncertain answer as a diagnosis.
