In a town with as much development as Tadley, from modern urban expansions to sensitive suburban renovations, a Pre-Build Survey is the most critical step in your project’s lifecycle.

We identify the exact location, depth, and condition of pipes, ensuring your foundations are designed correctly and your Tadley planning application proceeds without a hitch.

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