Frequently Asked Questions
Why do I need a Pre-Build Survey for my Essex extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Essex. It protects you and the water authority.
Will this survey satisfy Thames Water in Essex?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Essex building control.
What happens if you find damage during the Essex survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Essex build commences.
Do I need a post-build survey as well in Essex?
Often, yes. Water authorities in Essex 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 Essex?
Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Essex site since the check.
Can you trace the depth of the pipe for my Essex structural engineer?
Absolutely. Our Sonde and Trace technology provides the exact depth data Essex engineers need for footing designs.
Do you work with Essex-based architects?
Yes, we are the preferred drainage partner for many architectural firms across the Essex area for all pre-construction works.
Is the survey messy or disruptive to my Essex property?
Not at all. It is entirely non-invasive. We access the pipes through existing manholes on your Essex site.
