Report cracks in my house: where to start

A crack or a sticking door can mean very little, or it can be the first sign of subsidence. Describe what you have noticed and where it is on your home. The details go to a specialist firm in Cardiff who handles foundation repair.

  • No fee to send your question
  • Read by a local specialist firm
  • No obligation to accept anything

Describe what you have noticed

These details are passed to a specialist, as the privacy page describes.

Our privacy notice has more on what becomes of what you send. It goes to one independent underpinning specialist, and this website costs you nothing. Quotations from elsewhere are still yours to seek, and that firm may pay us at the point the enquiry is passed on.

Or send an email to hello@underpinningcardiff.co.uk

What happens after you press send

The form goes straight to a specialist underpinning firm covering Cardiff. They read the details about your home and decide which method applies, whether that is resin injection, mass concrete or monitoring. Any cost discussion is between you and them.

  1. The same day it is sent

    Your description of the crack or movement arrives with the specialist firm so they can see what type of problem it might be.

  2. Usually within two days

    Someone from the firm calls you to ask a few questions about the walls and the ground around your home.
