Frequently Asked Questions
Why do I need a Pre-Build Survey for my Lightwater extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Lightwater. It protects you and the water authority.
Will this survey satisfy Thames Water in Lightwater?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Lightwater building control.
What happens if you find damage during the Lightwater survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Lightwater build commences.
Do I need a post-build survey as well in Lightwater?
Often, yes. Water authorities in Lightwater 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 Lightwater?
Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Lightwater site since the check.
Can you trace the depth of the pipe for my Lightwater structural engineer?
Absolutely. Our Sonde and Trace technology provides the exact depth data Lightwater engineers need for footing designs.
Do you work with Lightwater-based architects?
Yes, we are the preferred drainage partner for many architectural firms across the Lightwater area for all pre-construction works.
