What Brazos Valley Homeowners & Businesses Say

Aggie-owned and family-run. Todd Cast, Licensed OSSF Installer II & Maintenance Provider, learned this trade alongside his dad — and brings that same integrity to every job in the Brazos Valley.

★★★★★
"We had Todd install a fairly large commercial septic system for us. As soon as we brought Todd in, the whole septic process became so much smoother. Todd is very responsive, knowledgeable, and willing to take the time to talk through all the details to make sure we understood. Todd also works really well with the county inspectors, which we found to be extremely valuable in helping with approval and making slight changes to the design. The job was done on time for a very fair price. I highly recommend!"

"Responsive, knowledgeable, conscientious, great value & quality. Todd and team did terrific job installing our Aerobic system & even assisted with the electric hook up. They also smoothed the dirt as requested and just did an overall fantastic job. Couldn’t be happier with the entire process. This has been, by far, the smoothest part of building our home so far. Would definitely recommend to everyone without hesitation."
