Storefront door calls we handle in Larkspur

  • 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 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 Larkspur 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.

How Storefront Entrances Works in Larkspur, CA

  1. 1

    Entrance evaluation

    We measure the door and frame for square, check the pivots and closer, and identify whether the problem is hardware, alignment, or a failing frame.

  2. 2

    Written scope

    You receive pricing for the repair path and, where relevant, for replacing the leaf or full entrance — including glass type and hardware finish.

  3. 3

    Glass and framing work

    Tempered or insulated units are ordered to size; corners are re-squared and re-fastened, and damaged rails, stiles, or framing are replaced.

  4. 4

    Hardware installed

    Pivots, hinges, closers, thresholds, weather seals, locks, and panic hardware are installed and adjusted to spec.

  5. 5

    Final adjustment

    The entrance is cycled, latching verified, closer sweep and latch speeds set, and egress function confirmed.

Storefront Entrances in Larkspur, CA — FAQs

Can you send a technician to Larkspur for storefront entrances?

Yes. Larkspur is inside our Northern California service area, and we dispatch to Larkspur and nearby Marin County communities from our Sacramento base. Scheduling depends on the job, so send the address and the problem and we’ll confirm availability.

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.

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.

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.

How far is Larkspur from your base?

We dispatch from Sacramento. Larkspur is roughly 72 miles southwest of our base, inside our 100-mile service radius.

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.
