I am so thankful I found Claude! He knew right away what the problem was and it ended up being a very simple fix! He was so accommodating - even came out on a Saturday! Top notch service from a very top notch family company!

As a first time customer, we were very pleased with the service. Claude & Sarah arrived the same day and finished the fix the next day. The price was fair, the work was excellent and they've given us a couple more years before our old system is going to need an upgrade. Septic Diagnostics will be the first call we make for any issues with our septic system. One never looks forward to needing septic service, but when we have an issue.... we are confident we'll get the best service and advice.
