Frequently Asked Questions
Why do I need a Pre-Build Survey for my Grays extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Grays. It protects you and the water authority.
Will this survey satisfy Thames Water in Grays?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Grays building control.
What happens if you find damage during the Grays survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Grays build commences.
Do I need a post-build survey as well in Grays?
Often, yes. Water authorities in Grays may require a “Post-Build” check to ensure your construction hasn’t damaged the sewer.

Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Grays site since the check.
