★★★★★

Brighthaus handled our detached ADU start to finish — permits, electrical, plumbing, everything. We now earn $2,400/month in rental income. Best investment we I\'ve made in our San Diego home.

Plumbing emergency on a Sunday — here in under an hour. Fixed the burst pipe and spotted our failing water heater before it became a second disaster. Best plumber in San Diego County.

AC out during a San Diego heat wave. Same-day, honest diagnosis, fixed without trying to upsell a new unit. Charged exactly what they quoted. Will use Brighthaus for everything.
