Services & Process

Bob Mahoney's combination of plumbing and excavating services makes them capable of handling septic work that goes beyond simple pumping. Excavating is essential for drain field repairs, tank replacements, and new system installations, all of which require digging. On the plumbing side, they can address pipe repairs, line clearing, and connections between the home and the septic system. For property owners dealing with a failing system that needs significant ground work, having a contractor who handles both sides of the job can simplify the process considerably.

Service Area

Bob Mahoney Plumbing and Excavating serves Arnold and the surrounding Jefferson County area. Nearby communities like Barnhart, Pevely, and Festus are within reach, as are the more rural areas of Jefferson County where private septic systems are the norm rather than the exception.

Frequently Asked Questions

What does septic excavating actually involve, and when is it necessary?
Septic excavating means using heavy equipment to dig down and access buried components like the tank, distribution box, or drain field lines. It's necessary for tank replacements, major drain field repairs, and new system installations where the ground needs to be opened up to do the work properly.
How do I know if my drain field is failing on my Arnold, MO property?
Signs of a failing drain field include soggy or spongy ground above it, sewage odors outdoors, toilets and drains that back up frequently, and lush green grass in a specific pattern over the field. A professional inspection can confirm whether the field needs repair or replacement.
Can a septic system be repaired, or does it always need full replacement?
Many septic issues can be repaired rather than replaced, depending on what's failed. A damaged pipe, a cracked distribution box, or a clogged inlet baffle can often be fixed without replacing the entire system. A thorough inspection is the first step to knowing which option makes sense.
What permits are required for septic work in Jefferson County, MO?
Jefferson County requires permits for new septic installations and major system repairs, and the work must meet Missouri Department of Natural Resources standards. Your contractor should be familiar with local permit requirements and can typically help you navigate the application process.
How long does a septic system installation take in the Arnold area?
A standard residential installation typically takes two to four days once permits are in place and the site has been evaluated by a soil engineer. The timeline can extend if weather delays excavating or if the site has challenging soil conditions that require a specialized system design.
What should I do if my septic system backs up on a weekend or holiday?
Stop using water in the home as much as possible to avoid making the situation worse, and call a septic service provider right away. Some providers in the Arnold area offer emergency response, so ask about after-hours availability when you call.
