Great company and great guys! The Caltech team was very helpful, informative and patient. They identified the problem I had with my system and provided an affordable solution while answering all my questions and provided insight on the work they will do. They started the job right away and was completed fast. Definitely worth using!

I am writing to express my deepest gratitude for your generous donation and installation of a new state-of-the-art septic system for my home. As a widow of a veteran on a fixed income, I was feeling hopeless and desperate when my old system collapsed. You came to my rescue and restored my faith in humanity by offering me a free system as a way of honoring my husband's service and giving back to the community.

This is a huge gift, and it brought me to tears. It gives me hope to know that there are still people like you in our world, who care about others and want to make a difference. I have never had a more professional, courteous, friendly, and hard-working team of people do work for me. I feel absolutely blessed by your generosity. You and your company are truly amazing, and I hope you know how much I appreciate your kindness and compassion.

You and your entire crew have given me a new lease on life, and I cannot thank you enough. You are true heroes, and I will always remember your gesture. Thank you again from the bottom of my heart.

Lance Bates and his company replaced our septic system leach field. The job was professional and quick. He explained all of the available options so I could make the best decision on how to proceed. The billing process and amounts were exactly as we discussed. He knew his way around the permitting process which eliminated any hassles on that score.
