Commercial door problems we assess in El Cerrito
- 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 El Cerrito can be a city department or the county, depending on where the property sits.
- We check 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.

- 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.

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.

Repair performed

- 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.

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