Overview
A defined scope across fire sprinkler systems.
Lee Mechanical designs and installs new fire sprinkler systems, retrofits and upgrades existing systems, and provides NFPA 25 inspection, testing, and maintenance — with an emphasis on reliability, coordination, and long-term performance.
Design
New System Design and Planning
Successful sprinkler systems start with proper design and planning. Lee’s in-house designers lay out each system to NFPA 13 and coordinate it with your building, with a focus on:
- SYSTEM LAYOUT AND DESIGN COORDINATION
- LONG-TERM MAINTAINABILITY
- WATER SUPPLY AND DISTRIBUTION CONSIDERATIONS
- INTEGRATION WITH BUILDING STRUCTURE AND SYSTEMS
- PLANNING FOR FUTURE EXPANSION OR MODIFICATIONS
The goal is a design that performs reliably, moves smoothly through plan review, and remains serviceable throughout its lifecycle.
Design · System Types
Supporting a Range of Sprinkler System Types
Fire sprinkler systems vary based on building conditions and environmental requirements. Lee supports:
This ensures the approach aligns with actual operating conditions, not a generic design.
Installation
New Fire Sprinkler System Installation
From new construction to building additions, Lee installs complete wet, dry, and preaction sprinkler systems, with pipe fabricated by Lee and the work coordinated with your general contractor and other trades. Installation includes:
- New construction and building additions
- Pipe fabrication and staging
- Coordination with the general contractor and other trades
- Hydrostatic and acceptance testing
- As-built drawings and closeout documentation
Installation · Retrofits & Upgrades
System Modifications, Retrofits, and Upgrades
Many projects involve working with existing systems rather than starting from scratch. Common scenarios include:
- Building additions or reconfigurations
- System modifications to match occupancy changes
- Outdated or undersized system components
- Repeated performance or reliability concerns
- Improvements driven by inspection findings or deficiencies
Lee helps evaluate existing systems and determine the most effective path forward—ranging from targeted modifications to larger system upgrades.
Inspection
Fire Sprinkler Inspection, Testing & Maintenance
Lee inspects, tests, and maintains wet, dry, and preaction sprinkler systems to NFPA 25. The standard sets a schedule that runs from weekly and monthly checks your staff can handle, through quarterly and annual inspections, to 3- and 5-year tests, and in Wisconsin the annual testing must be done by a state-credentialed tester. Service scope may include:
- RECURRING SPRINKLER INSPECTIONS
- FUNCTIONAL TESTING
- FIRE PUMP INSPECTION & TESTING
- SYSTEM CONDITION EVALUATIONS
- DOCUMENTATION OF FINDINGS
- DEFICIENCY IDENTIFICATION AND RECOMMENDATIONS
Long-Term Support
Maintenance, Repairs, and Follow-Up
Inspections are only part of the process. Many systems require follow-up work to maintain performance, including:
- Corrective repairs
- Component replacement
- System adjustments
- Performance troubleshooting
- Ongoing maintenance planning
A strong sprinkler program connects inspection results to clear, actionable next steps.
Long-Term Support · Performance
System Performance and Reliability
A sprinkler system must perform under real-world conditions—not just exist on paper. System performance is influenced by:
- Water supply conditions
- System design and layout
- Equipment condition
- Environmental factors
- Ongoing maintenance and inspection
Lee’s approach focuses on building systems that perform reliably and identifying improvements when existing systems fall short.
Long-Term Support · Evaluation
Evaluating Existing Systems
Not every situation starts with a defined project. Many customers are working with existing systems and need guidance. This may include:
- Systems with recurring deficiencies
- Performance concerns identified during inspections
- Expansion or reconfiguration needs
- Questions about system capacity or reliability
Lee helps review system conditions and determine the right next step—whether that is inspection, service, modification, or replacement.
