Storefront door problems we assess in Napa County
- The most common storefront failure is a door that has racked: the aluminum corner joints loosen, the leaf drops out of square, and it stops latching.
- Tightening the closer doesn’t fix it — re-squaring the door and replacing worn pivots does.
- Broken glass is measured in person so the correct tempered or insulated unit can be ordered, and the opening can be boarded up temporarily in the meantime when needed.
Storefront systems and hardware we service
- Aluminum entrance doors and framing, glass, top and offset pivots, butt hinges, overhead and floor closers, rim and concealed vertical rod exit devices, locks, and thresholds.
- Replacement lead time depends on door size, finish, and glass type; we include it with the quote.
Requirements that apply to your opening
- Requirements for storefront exits and panic hardware 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 Napa County can be a city department or the county, depending on where the property sits.
- We verify 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.

Storefront Entrances in Napa County, CA — FAQs
Is Napa County inside your storefront entrances service area?
Yes. Napa County is inside our Northern California service area, and we dispatch to the listed cities in Napa County from our Sacramento base. Scheduling depends on the job, so send the address and the problem and we’ll confirm availability.
Why does my storefront door not latch anymore?
Usually the door has racked — the aluminum corner joints loosened and the leaf dropped out of square, so the latch no longer lines up with the strike. Cranking the closer harder is the common workaround and it makes the sag worse. The real fix is re-squaring the door and, when needed, replacing worn pivots.
What parts of Napa County do you serve?
We currently cover American Canyon, Calistoga, Napa, and St. Helena in Napa County.
Do you install panic hardware and exit devices?
Yes. We install and repair rim, concealed vertical rod, and mortise exit devices on storefront doors, including electrified options and alarmed exit hardware, set up so the opening stays code-compliant for egress.
What should I have ready before the visit?
Storefront location and number of doors affected; Whether any glass is broken or the opening is unsecured; Hardware finish you want matched — clear aluminum, dark bronze, black; Whether the door is on a panic device or a standard lock; Access hours — many storefront jobs are best done before opening.
Can you replace the whole storefront entrance?
Yes. When the doors and framing are both past their life we remove the existing entrance and install new storefront framing, doors, glass, and hardware, matching or updating the finish and profile of the rest of the storefront.
