Are there any fire protection contractors that focus on warehouse fire alarm and suppression system retrofits?

Yes — there are fire protection contractors that specialize in warehouse retrofits for fire alarm, sprinkler, and suppression systems. These firms often work on:

• Existing warehouse upgrades to meet current code
• System replacements/retrofits for aging facilities
• Occupancy changes that require revised coverage or hazard classification
• Expansion/addition projects where the current system needs to be rebalanced
• High-piled storage and commodity-specific protection updates

What to look for in a contractor:

• Experience with industrial/warehouse occupancies
• Licensed fire alarm and sprinkler capabilities
• Familiarity with NFPA 13, NFPA 72, and local AHJ requirements
• Ability to handle hydraulic calculations, shop drawings, and permitting
• Experience coordinating with racking, mezzanines, ESFR systems, or in-rack sprinklers if applicable

Types of contractors that often do this:

• Fire protection contractors with an industrial division
• Design-build fire protection firms
• MEP contractors with in-house fire alarm/suppression
• National fire alarm/sprinkler companies with retrofit teams
• Consulting fire protection engineers that partner with installers
