What We Install

Handy Ivan helps with common safety device and detector projects, including:
Smoke & Carbon Monoxide Detector Installation

Smoke detectors and carbon monoxide detectors help provide early warning for homes, rentals, offices, and small commercial spaces. Handy Ivan installs and replaces customer-supplied detectors when the existing setup, mounting location, device type, and project scope are appropriate.

Common projects include smoke detector replacement, carbon monoxide detector replacement, combination alarm updates, and detector replacement during rental turnovers, property maintenance visits, or inspection correction lists.

Battery Backup & Hardwired Detector Replacement

Some properties use battery-only detectors, while others have hardwired detectors with battery backup. Handy Ivan can replace customer-supplied detectors at existing locations when the project is appropriate for the existing setup.

If the project requires new wiring, new interconnected detector systems, a new circuit, troubleshooting, or fire alarm system work, a licensed specialty electrical contractor or fire/life-safety professional may be required.

Rental, HOA & Property Manager Safety Updates

Safety device updates are commonly requested during rental turnovers, HOA maintenance visits, property management punch lists, pre-listing repairs, and general property maintenance. Handy Ivan helps property owners and managers complete practical detector replacements and safety-device updates with clear communication and responsive scheduling.
