Storefront door calls we handle in Los Altos
- 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 at the opening 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 work on
- 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.
Code, safety, and local requirements
- 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 Los Altos 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.

Storefront Entrances in Los Altos, CA — FAQs
Do you provide storefront entrances in Los Altos?
Yes. Los Altos is inside our Northern California service area, and we dispatch to Los Altos and nearby Santa Clara County communities from our Sacramento base. Scheduling depends on the job, so send the address and the problem and we’ll confirm availability.
How far is Los Altos from your base?
We dispatch from Sacramento. Los Altos is roughly 89 miles south of our base, inside our 100-mile service radius.
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.
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.
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.
