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