Customer Testimonials
ctest
Weeks has been our 60-year old well's caregiver for years. When it was time to replace the well, we contacted them. They were prompt with bids, patient with questions and concerns. Their team made what could have been a traumatic experience a rather enjoyable and educational ride. I would recommend them anytime; their customer service is priceless.
Shelly M. - Sebastopol, CA
Weeks has helped my family manage our well and water usage for over 25 years. Their service, expertise and guidance are invaluable. From well drill to water maintenance to water capture and drought mitigation, Weeks is my family's go to water-gurus. They are well priced, have unbeatable service and are longtime members and contributors to our community.
Daniel W. - Sebastopol, CA
Weeks really sticks to the contract...and ended up drilling a new productive well and installed 2 storage tanks, 1 pressure tank, a deep well pump system and an irrigation pump system. They always show up on time, are kind and polite, give you information, and do exactly what you expect them to do without any issues. I highly recommend Weeks Drilling.
