Ryan and Cameron were great to work with. They communicated well and did quality work at a very reasonable price. My project was not the biggest project but it was in a difficult to reach tight spot in my back yard. The team handled it well. I would hire them again.

Ryan and the Precision Earthworks team were very knowledgable, good communications and reasonable pricing so great value for the expertise. I would recommend him for any septic replacements or site work jobs. Thanks again!

I have a septic system at a small vacation home on a coastal river. It was 50 yrs old and needed to be replaced - immediately. Ryan came out and first debunked the over engineered quote I had received and then opened up his schedule to do the work quickly. He is a maestro with the backhoe first removing the old tank and then placing the new tank in place. He owned the job all the way through the inspection process. I am overjoyed with the results. His communication is timely and clear.

I’m Rick I called For an estimate on a repair on my sewer line. I tore it out while trenching. The owner called me back right away, I explained what I did and that I had an emergency because my drain field was on a pump system, and every time I turned the water on or flush the toilet the pump would turn on and flood the trench I had just dug. It turned was late Friday and instead of him making a ton of money on an emergency job that would have went into overtime Costing me even more money he asked if he could give me a suggestion.

Around Hillsboro, the main drain-field limit is slow water movement: water leaves the soil too slowly for a conventional field to keep up. Site conditions on any one lot can differ from the map. See the Hillsboro city page for the full soil profile.

Before You Call

A homeowner deciding between a perc test and an inspection can ask which starting point fits the planned septic work. That conversation can also establish whether the next step is repair, replacement or a new system design.
