Professional Roof Assessment & Leak Detection Service

Thornton Consulting brings decades of specialist waterproofing and leak detection knowledge to help commercial property managers and building owners in Tonbridge and the surrounding West Kent area. We integrate best-in-class, sophisticated electronic detection methods with thorough investigative analysis, ensuring your roofing systems remain stable and in optimal condition all year round, all while protecting your investment from the significant costs associated with water ingress damage.

Serving commercial buildings in Tonbridge, from town centre retail and office developments to industrial estates and business parks, we address both immediate leaks and long-term prevention and protection strategies. Whether investigating active water ingress, establishing thorough inspection programmes, or providing detailed documentation for property assessments, we can help. Our services encompass professional building leak investigations, strategic planned roof inspections, and rigorous waterproof integrity testing, helping you avoid costly emergency leak and roof repairs through proactive maintenance.

How We Work

  • Planning

    We begin every project by thoroughly examining your building's specifications, characteristics, and waterproofing quality. This allows us to deploy the most effective testing methodologies whilst accommodating your business schedule and minimising disruption.

  • Testing

    Our experienced waterproofing technicians utilise calibrated leak detection equipment for commercial premises. Whether employing low voltage testing, pinhole detection, or differential pressure techniques, we methodically survey all waterproofed areas to achieve comprehensive coverage and reliable results.

  • Evidence

    All findings receive documentation to include, comprehensive photography, and detailed technical records. This rigorous evidence collection provides contractors with quantifiable measurements with precise mapping data, streamlining the repair tendering process and reducing unnecessary assessments or guesswork.

  • Recommendations

    We translate technical data into actionable guidance, categorising defects by urgency and potential severity. Our recommendations will include immediate repairs as well as longer-term maintenance strategies, supporting your budget planning and risk management.

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.

FAQs

What's involved in a typical leak detection survey?

An average leak detection survey begins with a site meeting where we discuss your specific concerns and inspect the affected area(s). We then conduct a systematic electronic survey of the waterproofed surfaces, which involves applying detection equipment across the roof area in a methodical and non-destructive pattern. As we work, we mark and photograph each detected breach. Throughout, we maintain clear communication about our findings and can often provide preliminary observations on site, followed by a detailed written report with annotated plans showing exact leak locations.

Will your testing damage our newly installed roof?

Absolutely not. Our electronic testing methods are specifically designed to be completely non-destructive, making them ideal for quality assurance of new installations. The electrical currents used in our testing are extremely low voltage and cannot harm the membrane or underlying structure. There’s no physical probing, cutting, or invasive investigation involved.

Can you provide emergency call-out services?

Whilst we’re not a 24/7 emergency leak response service, we understand that serious leaks can cause significant disruption and damage to operations. We make every effort to respond quickly to urgent situations, typically aiming to attend between 24 and 48 hours of your initial contact, and often sooner depending on our current commitments and your location. It’s worth noting that some emergency leak situations may require immediate temporary measures before our diagnostic investigation can proceed effectively.
