Service areas

Northern California, crews out of the East Bay.

Our license is a California license and it is good anywhere in the state. Where our crews actually work day to day is a smaller map, and it is worth being straight about the difference.

The license and the map are two different things

A California contractor license is a state license. Ours, number 1006147, is valid anywhere in California, and a contractor telling you they are "licensed in your area" is telling you nothing that is not also true of every other licensed contractor in the state.

The more useful question is where a company's crews actually work day to day, because that is what determines whether they can get to you on the second day of a problem as readily as on the first. Ours are based in the East Bay, and the counties below are where our work has been.

Why the distance question is really a duration question

How far we will travel is not a fixed radius, and any contractor who gives you one is simplifying.

What actually matters is how long we would be on site. A two week scope two hours away is straightforward, because the crew is there for the duration and travel happens twice. A half day call-out at the same distance is a bad arrangement for both of us, because you are paying for windshield time and we are not going to be your fastest option when something goes wrong.

So the honest answer is: tell us the size of the job and how long we would be there, and we will tell you plainly whether we are the right firm for it. Sometimes the right answer is a contractor closer to you, and we would rather say so.

Response time is worth asking about separately. Being willing to travel for a project is not the same as being able to respond to a problem. If what you need is a contractor who can be on site quickly when something fails, proximity matters more than it does for planned work. Ask that question specifically, of us and of anyone else you are considering.

Where we are based

Ecostep is a California corporation operating out of the East Bay, with our own millwork and CNC shop. The shop matters to the service area question more than it might appear: machined panels, casework and fabricated fitting covers are made in our building and delivered, which means a good deal of the work on any given project happens before anybody travels anywhere.

Coverage

County by county.

Two tiers, and the difference is honest rather than marketing. Core means our crews and our shop are there. Regular means we work there routinely on projects, though we would not claim to be your fastest call-out.

Core area

Contra Costa County

Where the company is based and where most of our work sits. Concord, Walnut Creek, Martinez, Pittsburg, Antioch, Richmond, San Ramon and Danville are all short runs for our crews, and our millwork and CNC shop is in the county.

Core area

Alameda County

Oakland, Berkeley, Fremont, Hayward, Livermore and Pleasanton. The East Bay industrial and light manufacturing base is the natural home for mechanical insulation and process piping work, and it is a core county for us.

Regular

San Francisco County

Commercial and institutional work, tenant improvements and occupied renovation. City work brings its own constraints on access, parking, hours and permitting, and those belong in the plan rather than in a change order.

Regular

San Mateo County

The Peninsula, including life sciences and commercial facilities. Regular project territory, reached down either side of the Bay depending on what the traffic is doing that week.

Regular

Santa Clara County

San Jose and the South Bay. Data centers, semiconductor and cleanroom facilities, and the mechanical scope that comes with them. Further from base, so better suited to project work than to short call-outs.

Regular

Marin County

North of the bridge for commercial and institutional projects. Worth asking about for a scope that keeps a crew on site, less so for a half day visit.

Beyond these six. Our license is a California license and it is valid statewide, so licensing is never the constraint. Whether a job further out makes sense depends on how long we would be on site, not on how far away it is. Ask, and you will get a straight answer rather than a radius.

Questions we get asked

Coverage, plainly.

Will you travel outside the Bay Area?

For a scope that justifies it, yes. The deciding factor is how long we would be on site rather than how far away it is, because a project that keeps a crew in one place for weeks absorbs travel in a way a short call-out does not.

Tell us the size and the duration. That is enough for us to give you a real answer in one conversation.

Do you do emergency call-outs?

Proximity matters far more for that than for planned work, so the answer depends heavily on where you are. Within our core area it is a reasonable ask. At the edge of our range, you are better served by someone closer and we will say so.

If rapid response is a requirement rather than an occasional need, raise it early. It should shape who you hire.

Does your license cover my county?

Yes. A California contractor license is statewide, so licensing is never the constraint anywhere in California.

What varies is local permitting, which differs by jurisdiction, and which is something we handle as a matter of course on projects where we hold the prime contract.

Can you fabricate for a job outside your area?

Often, and it is a sensible arrangement. Machined panels, casework and fabricated fitting covers are made in our shop regardless of where they end up, and shipping finished components is a different proposition from sending a crew.

Several of our clients take the fabrication and handle installation themselves. Tell us which you want.

Next step

Outside the map? Still ask.

For a scope that justifies it we travel. The honest answer depends on the size of the job and how long we would be on site, so tell us both.
