Hollow metal openings we inspect in Tuolumne County
- We start by checking the frame: whether it is plumb and sound, whether its label matches the rating the opening needs, and whether the hardware preps line up.
- That tells us if the existing frame can stay or needs replacement.
- Stock sizes and common ratings can arrive quickly; custom sizes, welded frames, and special finishes take longer.
- Lead time is part of the quote.
Doors, frames, and hardware we install
- Hollow metal doors, welded and knock-down frames, and the hardware that goes with them — hinges, closers, exit devices, locksets, coordinators, and gasketing — installed to template.
- On a rated opening the hardware is part of what makes the assembly compliant, so we specify and install it as a set.
Fire-rated openings and local requirements
- Requirements for a hollow metal opening 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 Tuolumne County 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.

Hollow Metal Doors in Tuolumne County, CA — FAQs
Can you send a technician to Tuolumne County for hollow metal doors?
Yes. Tuolumne County is inside our Northern California service area, and we dispatch to the listed cities in Tuolumne County from our Sacramento base. Scheduling depends on the job, so send the address and the problem and we’ll confirm availability.
What parts of Tuolumne County do you serve?
We currently cover Jamestown, Sonora, and Twain Harte in Tuolumne County.
Can you replace just the door and keep the existing frame?
Often yes, when the frame is plumb, sound, and its label is intact and matches the required rating. We verify frame condition and hardware prep locations first — a new door hung in a racked or unrated frame doesn't give you a compliant opening.
Do you install the hardware too?
Yes — hinges, continuous hinges, closers, exit devices, locksets, thresholds, coordinators, and gasketing, installed to template. On rated openings the hardware is part of what makes the assembly compliant, so it isn't something to leave to another trade.
How do I know if my door needs to be fire-rated?
Look for a metal label on the hinge edge of the door and on the frame — it states the rating. Rated openings are typically required at stairwells, corridors, occupancy separations, and mechanical rooms. If a label is missing or painted over, the opening usually needs to be re-established as a rated assembly.
What should I send before you come out?
Opening location, size, and handing (or we field-measure); Required fire rating if known, or a photo of the existing frame label; Wall construction — stud, masonry, or existing frame reuse; Hardware needs — panic device, lockset, closer, card reader prep; Whether the opening must stay secured during the swap.
