One-Time and Regularly-Scheduled Septic Tank Pumping Services for Stanislaus, Merced & San Joaquin County

Our comprehensive septic cleaning and maintenance services can be scheduled on an as-needed basis or as a regularly scheduled service. This makes them ideal for property management companies, hotels, and homeowners throughout Merced, Stanislaus, and Merced County. At A-1 Septic, we recommend pumping your septic tank every three years to ensure the proper functioning of your entire septic system. Our experienced, well-trained pump truck drivers use the industry's best practices to ensure a thorough cleaning, which usually includes thoroughly pumping out both sides of your septic tank (solids and liquids). If you don't know the location of your septic tank, we can locate it for you using either manual or electronic septic tank locating, and can excavate your tank cover if necessary.

We Have the Knowledge & Experience to Recognize Signs of Septic System Problems or Potential Failure

During a septic tank cleaning, our experienced staff looks for any signs of potential leach field or septic tank failure, such as cracks in the tank, incorrect piping, leaks, or wet spots in the areas surrounding your septic tank. If we discover any potential problems, we will let you know immediately. We can also offer expert advice on the proper usage and maintenance of your septic system, which can help you avoid future costly repairs.

Effective Septic Tank Enzymes For the Proper Functioning of Your Septic Tank and Septic System

A-1 Septic sells natural bacteria septic cleaner that keeps your septic system balanced and functioning at an optimal level. Cleaner Innovations™ septic cleaner comes in easy-to-use, 2 oz. water soluble packets. Simply drop them into your toilet bowl and flush! The enzymes in Cleaner Innovations work to counteract the effects of modern chemical products such as antibacterial soaps and chlorine cleaning products, which can destroy the ecosystem within your tank. This ecosystem needs to be preserved in order to effectively break down solids in your tank so they don't get too thick and start clogging your system. We can add Cleaner Innovations directly into your tank as part of our pumping service for an additional fee.

Contact Us Today To Schedule a Professional Septic Tank Inspection & Certification

A-1 Septic also provides expert septic tank inspections and certifications for real estate agents, homeowners, and property managers at reasonable prices. Give us a call today to arrange a convenient appointment for one of our inspectors to visit your property in or near Modesto, Oakdale, Escalon, Ceres, Salida, and Riverbank. Though you are welcome to observe the inspection, we can also complete inspections without the owner being present on the property, as long as we have prior consent.

Awesome prompt service, they came out and pumped out multiple septic tanks for our company already before we demo them and tie the sewer lines to the city main. The drivers are always super nice and make sure they clean up after themselves. We will definitely be doing further business with this company.
