Frequently Asked Questions
Why do I need a Pre-Build Survey for my Charvil extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Charvil. It protects you and the water authority.
Will this survey satisfy Thames Water in Charvil?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Charvil building control.
What happens if you find damage during the Charvil survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Charvil build commences.
Do I need a post-build survey as well in Charvil?
Often, yes. Water authorities in Charvil 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 Charvil site since the check.

Absolutely. Our Sonde and Trace technology provides the exact depth data Charvil engineers need for footing designs.
