Commercial door calls we handle in Sonoma County

  • Usually the first sign is a symptom: a door that drags on the threshold, a closer that slams or won’t latch, a leaf that has dropped out of square, a spring that let go, or a rolling curtain that jumped its guides.
  • We inspect the whole assembly in person under real operating conditions, because a closer that keeps failing is often telling you the frame moved.
  • We don’t diagnose remotely — photos help us prepare, but the call is made at the door.

Doors and hardware we maintain and repair

  • Hollow metal doors and frames, aluminum storefront entrances, automatic doors, rolling steel and sheet doors, sectional overhead doors, and dock doors — plus the closers, hinges, pivots, exit devices, locks, and thresholds on them.
  • We are commercial and industrial only.
  • We do not service residential garage doors.

Code, safety, and local requirements

  • Requirements for a repaired door depend on the specific opening — its fire rating, egress role, accessibility function, and the occupancy of the building.
  • They are set by the building and fire authority with jurisdiction over your address, which in Sonoma County can be a city department or the county, depending on where the property sits.
  • We verify what applies to your opening before recommending work, and we tell you when a component repair is not the same as a full compliance inspection of the assembly.

Our 5-Step Commercial Door Repair Process

  • In Sonoma County, our work follows 5 service-specific steps, from on-site diagnosis through operation verified.
  • The detailed process below explains what each stage covers so you know what to expect before requesting a visit.

How Commercial Door Repair Works in Sonoma County, CA

  1. 1

    On-site diagnosis

    A technician inspects the door, frame, springs, tracks or guides, hardware, and operator under real operating conditions — not just the part that was reported.

  2. 2

    Repair vs. replace call

    You get a straight answer on whether the door is worth repairing, with pricing for both paths before any work starts.

  3. 3

    Repair performed

    Most repairs — springs, cables, guides, tracks, closers, hinges, pivots, thresholds, locks, panic hardware, alignment — are completed on the first visit from truck stock.

  4. 4

    Parts ordered when needed

    For obsolete or specialty components we source the correct part and schedule a return visit, securing the opening in the meantime.

  5. 5

    Operation verified

    The door is cycled, latched, and checked for safe operation, proper closing and latching, and code-required egress before we leave.
