Zero Downtime with the Right Extinguishing Technology

Downtime costs a manufacturer lost production, lost profit, and lost customers. When a fire threatens your high-priced equipment, selecting the right technology extinguishes the fire quickly and limits the damage.

A poorly maintained system is a risk to your operation. Keystone’s inspection service identifies issues before they become costly liabilities. We offer unobtrusive service visits and the convenience of after-hours inspection and testing if needed.

Property Management

Minimize Tenant Interruptions with Commercial Fire Protection Solutions

We understand that happy tenants are a property manager’s number one asset. Business interruptions such as frequent false alarms and ringing bells can alienate tenants, leading to a loss of rental income and potential vacancies. With this in mind, we coordinate all service visits with minimal interruption while keeping your property code compliant. Our flat-priced multi-year service agreements fix your fire protection maintenance cost to preclude the need for tenant rent escalation.

Schools & Universities

Keystone participates in COSTARS, a cooperative purchasing program.  >> Read More

A school’s schedule provides limited opportunities throughout the year to install, service, and maintain the life safety systems that protect your children. Most service happens during the summer months, but in times where we must provide service during the school year, we coordinate all visits with minimal interruption to students and staff. Plus, our technicians pass necessary background checks and carry credentials to work in school environments for parents’ peace of mind.
