I first called Edisto Realty to ask for a septic tank pumping company (If you are new to an area and need a service, I recommend calling a local real estate office.) Edisto Realty enthusiastically recommended A-1 out of Johns Island. A-1 arrived on time and finished pumping out our septic tank in a timely manner. The gentlemen who did the work were courteous and professional. I would highly recommended A-1 Septic Tank Service. PS: the price was a good price for the services rendered.

BEWARE BEWARE BEWARE.... this is one sick individual... He doesn't listen and wants to do all the talking, thus not listening what you have to say... He then showed up after 2 weeks of waiting ( was told one week ) and proceded to call me a LIAR.... i would never recommend this outfit to anyone... I feel sorry for his workers who seem to be fine people.

A-1 pumped out our septic tank. The work was performed well. The price seemed fair. They were not on time for the appointment; the appointment time was a 4-hour window and they arrived 2 1/2 hours after that. I called the company during the 4-hour window to double check when they would arrive. I was told that they "might" be on an emergency call. No word again from anybody until the driver called and said they were coming. A call from the office with an update on the arrival time would have been appropriate.

We have used this company for years and always give us reliable service and fair prices when one of our 15 tanks or fields go bad. They also use the more preferred chamber system which works well in confined spaces with minimal disruption of surroundings.

I had to make a 2nd appointment because no one showed up OR called for the first appointment. Apparently there was an issue with the truck and no one bothered to reach out to mention they’d be late/need to reschedule. THEN, they were 1.5 hours late for the second appointment. When I called to speak to the owner, I could almost feel the shoulder shrug though the phone. NOT someone I’d ever do business with again nor recommend to anyone else.

The Summerville location for this Service is TERRIBLE!!! For approximately 3 1/2 weeks I have been waiting for a quote. Yesterday, I was told, "Oh Cindy is at lunch! I'll tell her to give you a call back. I Recieved NO CALL!!! Today I was told oh Cindy has gone on VACATION!!!!!! Really?? All I needed was a quote. I fax the info approximately 3 1/2 weeks ago that was needed to get the quote. Oh ma'am I'm sorry we're a small business and we have been swamped for the longest. I stated she call once out of the 3 1/2 weeks but left no price. That rep is clearly a untrained child!! So my response was
