Most electricians cover their work for a year, maybe two. We cover ours for as long as you own your home. If something we installed ever fails because of our workmanship, we come back and fix it — no charge. That's not common in this trade. We do it because we stand behind what we build.
Upfront pricing, no surprises
We tell you the price before we start. That's the price you pay. No mid-job calls saying we found something extra. Regular service calls are $85. Emergency and after-hours calls are $125. Both fees are waived if you move forward with the repair.
Fast 24/7 Response Service
Electrical problems can’t wait. DNZ Electrical Services responds quickly to service requests across Agoura Hills and surrounding communities when you need electrician near you. to get your power and safety restored as soon as possible.
Free outlet tester with every job
When we wrap up a job, we hand you a plug-in outlet tester and show you how to use it. It's a $25 tool that lets you check any outlet in your home for wiring problems.
No other electrician in Ventura County does this. We think you should be able to spot basic safety issues yourself — not wait for a service call.
