Frequently Asked Questions
Why do I need a Pre-Build Survey for my Woodstock extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Woodstock. It protects you and the water authority.
Will this survey satisfy Thames Water in Woodstock?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Woodstock building control.
What happens if you find damage during the Woodstock survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Woodstock build commences.
Do I need a post-build survey as well in Woodstock?
Often, yes. Water authorities in Woodstock may require a “Post-Build” check to ensure your construction hasn’t damaged the sewer.
How long is a Pre-Build Survey valid for in Woodstock?
Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Woodstock site since the check.
