Foundation & Footing Excavation

Excavation for residential additions and accessory structures. We dig footings and foundation trenches to the depth and line on your plans, then hand off a clean, ready dig and look after the rest of your property while we're at it.

What you get

What you get

The goal is simple: leave your site ready for the next crew, with no rework and no surprises.

Laser-Set Depth & Line

We take the engineer's drawings to the ground with laser grade control, holding the depth and footing dimensions so the concrete goes in right the first time.

Careful Soil Handling

We keep topsoil and subsoil separate, then either stockpile clean fill on site for backfill or haul it off. Your lawn and beds stay protected the whole time.

Trenches Ready to Pour

Walls cut clean, bottoms dressed by hand and clear of loose spoil, compacted where the spec calls for it. A solid base for footings and forms.

Right-sized for the job

Adding to your home shouldn't mean wrecking the yard around it. Our fleet runs from a tracked skid steer that fits a backyard gate up to a 5-ton excavator, so we can get into narrow side yards full-size equipment can't and still dig a proper foundation.

  • Where we work

    Sunroom addition, detached garage, pool house footing, backyard shed pad: whatever it is, we plan the access, lay ground protection where it's needed, and keep the mess around the dig to a minimum.

How a job goes

From the first call to a clean handover

  1. 1. Site Walk

    We come look at the property by appointment, check the access and any constraints, and go over your plans or what you have in mind.

  2. 2. Marking & Layout

    We set the layout on the ground with laser accuracy. Depths, lines, and elevations are marked before anything gets dug.

  3. 3. The Work

    We bring the right machine for the access, lay ground protection where it's needed, and keep the mess around lawns, trees, and hardscape to a minimum.

  4. 4. Clean Handover

    You're left with a site that's ready to go and a yard that's still in one piece, set up for whatever's next.

Frequently Asked Questions

Our most compact machine, a tracked skid steer, needs about 36 inches of clear width, so it can usually fit through a standard backyard gate without taking down fencing. Bigger machines need more room. When we walk the site we confirm the access for whatever the job calls for and protect the turf and hardscape along the way.
