Recommended Customer Reviews

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.

I can't say enough good things about this company. After calling several local Santa Clarita companies with no luck, I found Acosta & Sons on Yelp.
From first contact with Marisol I knew I picked the right company. She was extremely knowledgeable and straight forward with everything. Our project was converting a failing 1950s septic tank over to sewer. With the exception of a few minor hiccups caused by the city and their never ending paperwork shuffle, the project stayed on timeline and didn't go over the quote.
The foreman (sorry his name escapes me) and the crew were extremely professional and for what is a nasty job, kept everything clean and tidy daily. When the job was completed you couldn't even tell that they were ever there.
I'm extremely happy with them and would gladly recommend them to anyone! Thank you again for all your time and hard work.

Acosta and Sons installed our septic tank a year ago, very nice and friendly people. Whenever i need something or i have a question i get very fast responses and solutions. And yesterday i contacted for the service and 2 hours later our septic tank was cleaned. Also fair prices. Thank you!!

The house I bought had a fully imploded septic system. I got quotes from four plumbers/septic specialists. Not only was Acosta & Sons literally thousands of dollars more affordable, they were happy to to talk me through each part of the process, educating me about what needed to happen and why. Their plumbers (who were polite and managed to finish in about two and a half days what all the other quotes had said would be a week's worth of work) took photos and videos that they shared with me so I could keep them for my records. I am a very satisfied customer.

I have an older septic system that is completely underground. I wasn't even sure where it was located. All I knew was there was some water in my backyard and it smelled horrible. I contacted Acosta on a Thursday and they came first thing today, Monday. I contacted 2 other places and one didn't respond and the other said they don't dig/locate tanks. It took about an hour with digging and pumping and it was well under $500. I swore I was gonna have to use two different companies to get the job done and pay over $700, thankfully I found Acosta and Sons. Bernie was extremely nice and very informative. He gave my husband some recommendations regarding our current set up (which is not an ideal one) and a number to someone who specializes in that area. Bernie and his team made the whole ordeal so easy and for that I am so thankful. I highly recommend this company if you have any type of septic needs.
