Storefront door issues we diagnose in Sonoma 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 on site 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 maintain and repair
- 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.
Local requirements and safe operation
- 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 Sonoma 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 Sonoma County, CA — FAQs
Is Sonoma County inside your storefront entrances service area?
Yes — we cover the listed cities in Sonoma County from Sacramento. Timing depends on the scope of work; share the address and what the door is doing and we’ll confirm.
Which Sonoma County cities do you cover?
We currently cover Cloverdale, Cotati, Healdsburg, Petaluma, Rohnert Park, Santa Rosa, Sebastopol, Sonoma, and Windsor in Sonoma County.
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.
How long does a storefront door replacement take?
Once materials arrive, most single-door replacements are completed in a few hours. Lead time on the door and glass is the long pole — typically one to a few weeks depending on size, finish, and glass type.
Can you replace broken storefront glass?
Yes. We measure the opening, order the correct tempered or insulated glass unit, and secure the opening in the meantime with a temporary board-up when needed. Standard tempered lites are usually available quickly; custom insulated or tinted units take longer.
What should I send before you come out?
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.
