Kyle and his dad came out. Such wonderful people with zero shadiness. They showed me a lot and gave a lot of advice. Honestly it's all about trust and this company has mine. Great prices and zero hidden tac on fees. Great experience and will be using them from now on. read more

I called Williams Sanitary Service with a fairly simple request. The person who came out to complete this request, was extremely, extremely, rude, talked over me multiple times, and would not listen to what I was needing from them, which made the process of getting what we needed about 3 times longer than it needed to be. I would not recommend working with this company. Their communication style is poor and they are not good to work with. read more

These guys were very professional, provided great service, and were efficient--from the office staff to the on-site crew. They showed up on time and stuck to the quoted price. I would definitely recommend and reuse their services. Very personable and took the time to explain all my questions thoroughly. Great job, guys! read more

This is a horrible company and they are liars and all they want is MONEY! We have used this company to maintain our septic for years. Now, we are trying to sell our house. All of a sudden, during inspection we "NEED" a new tank. But through all these times we used them, NEVER once they mentioned we needed a new tank. I do not recommend this company if you have future plans. I would give negative stars if possible. Their qoutes are absolutely ridiculous. Do your own research and get better service and price elsewhere. read more

I highly recommend Williams Sanitary Services. Alberto and his crew are very knowledgeable and very helpful when it comes to doing their job!! read more

What a great crew! Worked hard, respectful, knowledgeable and while we hit some hiccups (no fault of theirs) they kept me informed and were cost conscious. Highly recommend Alberto and his team. read more

We were selling our house and the new buyers called out Williams to pump out tank and test system During the test which require running water down the drainline using a hose. He had a nozzle on the end that made the flow harder and sharper. This guy kept pulling out the hose very sloppily and kept knocking leaves and dirt into the drain. He failed the system. He said it was only 23 min when water started backing up. It should last longer than 30mins replicating a 30 min shower I got the gpm of a shower head which us .8gpm. 2 days later I did my own test. I used a flow rate of 2.5gpm and I got 77mins with no back up. I used twice the water and lasted over twice as long. The only difference was I only pulled the hose out every 15mins and didn't knock debris in the hole. The engineer who I used is good friends with Williams. I had problems with engineer. One of the inspections the engineer was going to be. The engineer wouldn't call me back. This was my chance to confront him. Williams knew this and changed the inspection time and didn't notify me. It cost me $36,000 for engineering and install. This whole industry is flawed If I didn't keep a close eye on it It would have cost ,,$60 to $80k Because of the engineer If you are putting in a new system, email me and I can share more info.

We've lived in our home on septic for 9yrs, the previous owners told us they could never find the septic tank after numerous attempts. We had tried to have the tank pumped out but no one at the county could tell us where it was. After talking with the staff at Williams they laid out a plan and sent out a great team to help locate our septic tank. In 7 minutes they were able to find a tank that had been hidden for 12+ yrs! They quickly dig up both boxes, tested the lines, pumped it out, inspected the boxes and covered the holes like they had never even been there. Something that was haunting us for for years was fixed in a matter of hours! EVERYONE from the office staff to the guys in the field were so friendly and so professional!! I cannot say enough good things about the whole team! Thank you Williams Sanitation read more

Whether it was septic pumping, septic inspections, or septic installation, (when our old system failed after many years), Darren Williams and now the new owner Alberto Solorio have provided the same quality of service. Our new system is now large enough to provide service to 2 homes on the property. The costs were very reasonable and affordable with an easy time frame of payments as each stage of the job was completed. Alberto's mantra was always "I want you to be happy". Not something you hear much from a contractor. If you have questions or are considering using a sanitary service they do not charge you just to come see your property and access your needs. Their services are septic pumping, septic inspections, septic installation, operations & maintenance of septic systems, rooter service, full service plumbing. read more

Prompt, courteous, knowledgeable, reasonable prices. Can't beat that! Will definitely call them again!

We hired Williams Sanitary Service to come out to our newly purchased property to help us figure out exactly was going on with the septic system there. From Amanda in the office to Kevin & Alberto in the field, every part of the process was handled effectively and efficiently. We had a unique situation and Kevin and Alberto were beyond knowledgeable, professional and really took the time to make sure we understood everything that was going on. They were like a super septic duo! I can't rave enough about this company and they will absolutely be the only service I recommend to anyone looking for help with septic! read more

They didn't do what they said they would do. They said they could do some repairs when they got here late they said they didn't do repairs. Would not recommend them ever. read more

All around great guys, professional and got the job done and then some. I would not hesitate to reccomend them for a job. Thanks guys for helping get the process started through to completion. Excellent job! read more

Not sure why they're rated high?! We'd nothing but issues scheduling the INITIAL meeting! First they told us they're one hour away & WE have to make sure our job is right for them!! They finally agreed on a date to visit the job site and when WE called to confirm, they did not have a record of the visit!? We decided to take the business to another "reliable contractor"! read more

These folks are the people you want to call if you live in Eastern Contra Costa County and you have a septic system problem. When our toilets started running slowly they came out within a couple of hours and made a temporary fix to get us through the weekend, then came back on Monday to dig up the tank and pump it out. Both the field crew and the office folks were friendly and know their stuff - the field crew did a nice job refilling the hole and cleaning up. Except for some missing ice plant that had to be dug up, you can't tell they were here. read more
