What We Offer

Turnkey Installation & Replacement

We field-measure rough openings, weld or knock-down frames, hang doors, set hardware, and label fire assemblies—all in one mobilization.

Retrofits & Frame Conversions

Swap warped wood doors for steel, convert existing openings to panic egress, or fire-label frames without full demolition.

24/7 Repair & Emergency Board-Up

Broken hinges, kicked-in frames, or failed closers? Our mobile weld rigs and stocked hardware bins get you secure the same day.

Preventive Maintenance & Fire-Door Inspections

Annual NFPA 80 inspections, torque checks, closer adjustments, and detailed digital reports keep your egress routes compliant.

How Our Process Works

Our Installation Process

  • Step 01

    Site Survey & Code Review

    We verify wall construction, clearances, and egress requirements, then map fire ratings, swing, and hardware sets.

  • Step 02

    Specification & Hardware Schedule

    You receive a clear submittal outlining door cores, frame profiles, finish, and electrified hardware wiring diagrams.

  • Step 03

    Fabrication & Finishing

    Doors and welded frames are fabricated, punched, and factory-painted or powder-coated for fast, clean installation.

  • Step 04

    Professional Installation

    Certified crews set frames plumb, hang doors, install hardware, and adjust closers and seals for smooth operation.

  • Step 05

    AHJ Sign-Off & User Training

    We coordinate fire-door drop tests or inspection sign-off, then walk your staff through daily checks and basic troubleshooting.
