Recommended Customer Reviews

Marisol and Bernie were absolutely amazing. During my home buying process, I found out that my septic tank needed to be certified. Marisol walked me through everything I needed to know about the system and sent out Bernie and his crew the next day to accommodate my need for an immediate turnaround!
Bernie and his crew were amazing and got the job done! I highly recommend Acosta & Sons for any septic needs. Thanks again for all your help!

If we could give Bernie Montoya 50 stars, we would. What a great guy and a great company. Seldom do you have a business under-promise and over-perform, but Acosta & Sons did that for us. On the heels of a very long list of VERY satisfied clients, I have to say Bernie was knowledgeable, personable, professional and very easy-going. He instilled confidence in us from the first moment my husband and I met him. Without going into details about septic and sewers, etc., suffice it to say that our problems were identified, addressed and dealt with in a manner that makes us eager to refer him to anyone with septic/sewer issues, without the least bit of hesitation. Don't even bother to call anyone else! This is your man! They are the best! We are thrilled. THANK YOU, ACOSTA & SONS!

Needed a small holding tank pumped. The pumper responded very promptly. Very friendly and professional. After finishing he showed me what he had done with a full explanation. Very reasonably priced.

I was so pleased to have this company help me with a 1960 home. In the old part of Woodland Hills. Nicest person and knew so much about the way to carefully get the lid off without breaking the main water line. Also I was surprised to learn that my tank was 1000 gal and not 500 like the looser pumper told me 20 years ago. That looser, stupid previous pumper messed my life up with Dept Building Safety when I wanted to get a permit for an addition. Cost me dearly. Many many thousands, 20 years ago. INSTEAD, Acosta did the job, measured my 1000 gal tank. Great price and less than one hour. Thanks again Acosta! Will be passing on your service to everyone and anyone!

I had Acosta & Sons locate my septic tank, install a new riser and pump the tank. After getting a fair estimate from their office staff, Bernie came out at no cost and checked out the situation, giving me a detailed quote, along with some thoughtful ideas of how to most efficiently improve my system. They were personable, knowledgeable and fairly priced. Aside from one scheduling snafu they were great. They did the work efficiently and carefully. I would definitely recommend them and I will be calling them again next time I need service for my septic system.

We had some questions about our old home in Northridge that, ""once upon a time"", before hooking into city sewage, there was some other septic or other system here. Anyway, Bernie came by, answered questions and helped figure out what our next step is to be. Great guy, knowledgeable and friendly!
He will be coming back for some additional work....
thanks Bernie !!!

Bernie at Acosta & Sons Sewer Contractors was professional and friendly. Very important to me is that they communicated all along the way and never left me wondering. Their prices were better than the other bids, and the work was thorough and completed to satisfaction. Job well done! Thank you Bernie and team! I recommend them highly!

Awesome service. I'm really too lazy to type this out tonight- but these guys came and fixed an issue that would have cost of a fortune if anyone else had done it. I'm so grateful to have found them.

I don't know if I've ever had such a great experience with any kind of contractor ever...but Bernie and his team from Acosta & Sons are amazing. We have been having a lot of trouble with our septic tank and system for a LONG time. And after consulting some other ""top"" septic contractors, we got Bernie to come out. He has since come to my house multiple times helping us troubleshoot, not upselling us, going out of his way and really beyond the call of duty. He even fixed my front gate latch which was broken...just to be nice! We are so relieved to have such a decent, honest good guy.

Bernie and his team are true pros. Was having a problem with my sump pump and was told by another company they'd have to completely tear up my seepage pit to fix the problem -- a cost of upwards of 20 grand!
Called Bernie for a second opinion and he correctly diagnosed my real problem before even opening anything up. All in all it ended up costing around 150 bucks. Quite a savings.
Very honest and reliable company, I'd do business with anytime.
