Jinwu

Who we are

A small practice. Named people, not a call center.

金烏

In the old stories the Jinwu is a golden three-legged bird who lives in the sun. Every morning it carries the sun up across the sky, and every evening it brings it home again. The same bird. Every day. Without being asked.

We chose it because it isn’t a claim about the sun. Anyone can point at the sun. It’s a claim about the carrying, and about doing it again tomorrow.

The people

Joshua DiMercurio

Joshua has worked in home improvement for over ten years and designed solar systems for the last four, through several rounds of change in how California treats them.

John has spent thirty years in home improvement, on projects across California. He’s drawn to the technical side of it — efficiency, and what actually works on a particular building — and to the part of the job where an owner finally understands what they’re being asked to buy.

Joshua’s registration is public — look it up by name or number at cslb.ca.gov.

How we work

Most of our work comes from someone we already know.
A past client, or the neighbour of a job we’re on.
No sales floor.
No quotas, no summer reps, no downline. The person who sells you the system is the person who answers the phone in year seven.
We’re not the contractor, and we say so.
The licensed contractor performs the work, pulls the permits, and carries the warranty. We tell you who they are before you sign.
We’d rather lose a deal than oversize one.
A bigger system is a bigger commission. It’s also, often, the wrong answer.
