About us
One vendor for everything your property needs.
One Stop Source began with a simple idea: property managers and HOAs shouldn't have to juggle a dozen contractors to keep their buildings running. So we became the one call that handles all of it.
Who we are
Built to make property maintenance simple.
For more than 25 years we've handled plumbing, construction, water and fire restoration, and mold remediation across Southern California — as a single, accountable vendor.
That means no chasing subcontractors, no finger-pointing between trades, and no gaps in documentation. One team scopes the work, does the work, and stands behind it.
Licensed, insured, and available 24/7, we're the partner property managers and HOAs trust when something breaks and when they're planning ahead.
What sets us apart
The way we work is the difference.
One accountable team
Every trade under one roof, so the same people who scope a job are the ones who finish it — start to finish, no hand-offs.
Always documented
Photos, reports, and clean records from the first call to the final invoice — everything you need for owners and claims.
Ready when you are
A real person answers 24/7. Whether it's a burst pipe at 2am or planned maintenance, we mobilize fast and communicate clearly.
