Trenching in Fallbrook costs $150 per hour with a 4-hour minimum, operator and fuel included. The mini excavator cuts about 100 to 150 feet of 18- to 24-inch utility trench in four hours in normal Fallbrook soil, and we backfill and track-roll it after your inspection. Rock, roots and steep ground add hours; we tell you which before we start.
Trenching is the part of a plumbing, electrical or irrigation job that nobody wants to do by hand, and in Fallbrook's decomposed granite nobody should. The mini excavator cuts a straight, clean trench at the width and depth the trade specifies, piles the spoil on one side for backfill, and moves on. Your plumber or electrician lays the line, the inspector signs it off, and we come back to close it.
We trench for new water services from the meter, irrigation mainlines, electrical conduit to shops, barns, wells, gates and pool equipment, low-voltage and fiber, drain lines and downspout runs, and the long runs to a new ADU. On rural lots that often means several hundred feet across a grove or down a driveway.
Every trench starts with a DigAlert (811) ticket, which is free and takes two working days. We will not cut near unmarked public lines. Private lines on your property are not marked by 811, so tell us about any you know of and we hand-dig around them.

The equipment
- Mini excavator with 12-, 18- and 24-inch trenching buckets, plus a thumb for the boulders Fallbrook ground hides.
- Bobcat T300 to move spoil, haul sand bedding to the trench and backfill fast after inspection.
- Hand tools for the last few feet near a meter, a foundation or a marked line.
Trenching in Fallbrook and North County
Fallbrook, Bonsall and Valley Center are full of properties on long private runs: a meter at the road and the house 400 feet up the hill, a well on one corner and the pump panel on another, a barn or a workshop that needs its own sub-panel. Those runs cross groves, driveways and hard DG, and a trencher stalls in all three. The excavator does not.
Depth in this area is set by the trade, not by frost. Local plumbers usually ask for 18 inches on a water service, electricians for 18 inches on PVC conduit and 24 inches on direct-burial cable, and irrigation contractors for 12 to 18 inches on a mainline. We cut to the number you give us so the inspector has nothing to say.
