Commercial door problems we assess in San Ramon
- 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 work on
- 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.
Local requirements and safe operation
- 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 San Ramon can be a city department or the county, depending on where the property sits.
- We confirm 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.

How Commercial Door Repair Works in San Ramon, CA
- 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
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
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
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
Operation verified
The door is cycled, latched, and checked for safe operation, proper closing and latching, and code-required egress before we leave.
