Client Testimonials

I’ve worked with Thornton’s team for nigh on 10 years and I’m yet to be disappointed by any aspect of their business or interaction with any of their staff. I feel that the collaborative approach we have when working together not only benefits our site in a speedy response and solution, but it also strengthens our relationship with our onsite client team, building in faith that together we can self-solve most, if not all issues. Working with Wendy and the onsite teams is nothing short of a pleasure. I would highly recommend using Thornton Consulting Group for all investigative services when it comes to finding leak issues.

We have worked with Thornton’s for several years now and we could not be happier with the service. The team are really helpful, accommodating and always happy to help us out if we are under pressure from a client. The team are always happy to take a call to discuss a project with them to get a clear understanding of the issues found on site. Thorntons always find the issues and provide a very thorough report to outline them with recommendations on repairs required.
