Hollow metal openings we inspect in North Highlands
- 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 North Highlands 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 North Highlands, CA — FAQs
Can you send a technician to North Highlands for hollow metal doors?
Yes — we cover North Highlands and nearby Sacramento County communities from Sacramento. Timing depends on the scope of work; share the address and what the door is doing and we’ll confirm.
Where do you dispatch to North Highlands from?
We dispatch from Sacramento. North Highlands is roughly 10 miles northeast of our base, inside our 100-mile service radius.
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 is a hollow metal door?
A hollow metal door is a steel door built from face sheets over an internal core, hung in a steel frame. It's the standard for commercial back-of-house, stairwell, mechanical, and exterior service openings because it takes abuse and is available in fire-rated assemblies.
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.
What is the difference between a welded and a knock-down frame?
A welded frame arrives as one rigid unit and is set before the wall is finished — it's stronger and standard on new construction and masonry. A knock-down frame ships in three pieces and assembles around an existing finished wall, which makes it the usual choice for replacement work.
