Electrical work for the way you use your home

Tell us what you want to change and what is happening with the existing system. We can discuss a focused repair, a room renovation or a larger electrical update.

Lighting and ceiling fans

Interior and exterior lighting, fixture replacement, lighting design and ceiling fan installation for everyday comfort and useful light.

Outlets, switches and wiring

New or replacement outlets and switches, wiring repairs and rewiring for homes where the electrical layout needs to change.

Panel upgrades

Review the existing service and planned electrical loads when considering a panel upgrade. Capacity, equipment condition and project scope guide the recommendation.

Remodels and home automation

Plan electrical changes alongside your remodel, including lighting controls and home automation needs. Share the equipment you want to use before work is scoped.

Start with your home, your priorities and your schedule

When you contact us, include your city, the rooms or equipment involved and whether the work is a repair or a planned improvement. Describe any recurring issue and when you first noticed it.

For larger changes, existing wiring and panel capacity can affect the work required. Vicente can discuss the next step and the information needed for an estimate. Permit and inspection requirements depend on the scope and local jurisdiction.
