Why Diablo Homeowners Choose Us

Built for Diablo weather and tested for California homes.

Hub-style wiring connections

Pierce-point connectors are the #1 reason landscape lighting in 94528 fails by year three. We use waterproof hub connections on every run.

Right-sized transformers

We size every transformer for 70% load. That leaves headroom for voltage drop, future expansion, and the LED inrush current most installers ignore.

Same-day service available

Need a repair or quick install in Diablo? Same-day and next-day service slots are available most weeks — call before noon for same-day response in 94528.

Free quotes, competitive pricing

Every Diablo project starts with a free on-site quote and itemized, competitive pricing in writing. No high-pressure sales, no surprise add-ons.

Ask Us Anything · (213) 752-3935
01Are permits required?
+

Low-voltage landscape lighting in CA generally does not require a permit. Line-voltage exterior circuits and any new sub-panel work do — we pull those when needed and coordinate with the inspector.

02Can you work with my existing landscape lighting?
+

Often, yes. We repair and expand existing low-voltage systems in Diablo as long as the transformer and trunk wiring are sized correctly. We'll evaluate it for free.

03Do you serve all of Contra Costa County?
+

Yes — Outdoor Home Lightings installs throughout Contra Costa County and adjacent areas. We service Diablo (94528) and surrounding cities listed below.

04How quickly can you start?
+

Most Diablo projects begin within 2–3 weeks of contract signing. Permanent holiday lighting in October/November books out further — we recommend getting on the calendar by September.
