Frequently asked questions
How should I choose an alarm installation company in San Francisco?
Look at verified online reviews, the company’s Google rating and number of reviews, and whether their listed Google category matches the service you need (installation, supplier, or guard service). Also confirm local licensing and ask for references, written estimates, and details about monitoring contracts before committing.
What should I check before an installer comes to my home?
Confirm the exact services included in the estimate, whether equipment, installation labor, and monitoring are bundled or separate, and any ongoing fees. Make sure the installer knows your property type, entry points, and any compatibility needs with existing smart-home gear.
How much does alarm installation typically cost?
Costs vary by system complexity, equipment quality, and whether monitoring is included; basic wired or wireless setups usually differ from full smart-home integrations. Get multiple written quotes and compare what’s included rather than relying on a single price.
