Security Grilles calls we handle in Loomis
- A rolling security grille is an open pattern of steel or aluminum rods and links that coils above the opening like a rolling door.
- It's the right answer when you need to secure a storefront, a mall tenant, a pharmacy counter, a concession, a parking garage entrance, or a corridor after hours — while still letting people see in and air move through.
- Grilles see a lot of cycles and a lot of contact from carts and hands, and their small components wear.
- Guardian Door LLC installs, repairs, and replaces manual and motorized rolling security grilles across Sacramento and Northern California.
- We service curtain links and rods, guides, bottom bars, locks and cylinders, counterbalance springs, and operators, and we upgrade manual grilles to motorized operation with key switches, remotes, or access control.
- Side-folding grilles are handled as well.
Requirements that apply to your opening
- Requirements for a rolling steel security grilles 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 Loomis 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.

Security Grilles in Loomis, CA — FAQs
Do you provide security grilles in Loomis?
Yes. Loomis is inside our Northern California service area, and we dispatch to Loomis and nearby Placer County communities from our Sacramento base. Scheduling depends on the job, so send the address and the problem and we’ll confirm availability.
Are you able to match a mall or center standard?
In most cases. Many centers specify a grille style and finish for tenant storefronts; send us the tenant criteria and we'll quote to it.
Can a manual security grille be motorized?
Usually yes. Most grilles can take a compact tube motor or a side-mounted operator with a key switch, remote, or access control input. We check the barrel and electrical availability first.
What should I send before you come out?
Location — storefront, mall, parking garage, counter, corridor; Opening dimensions and available headroom; Manual or motorized, and whether you want to add motor operation; Photos of the curtain and guides if damaged; Center or property management access requirements.
How far is Loomis from your base?
We dispatch from Sacramento. Loomis is roughly 23 miles northeast of our base, inside our 100-mile service radius.
Do you install security grilles for parking garages?
Yes — grilles are widely used at garage entrances because they secure the opening while preserving ventilation. We pair them with high-cycle operators and vehicle detection for that application.
