Smart Glass Front Doors
The most public glass in the house, finally on a switch — clear when you want the daylight and the view down the walk, evenly frosted a second later when you'd rather the street saw nothing at all.
Your front door is the only glass in the house aimed directly at strangers. It faces the street, the walkway, and whoever is standing on the mat, and the same full-height lite that fills the entry with daylight hands a clear view of your hallway to anyone who rings the bell. Every conventional fix trades one problem for another: permanent frosted or etched glass is a decision you can't reverse and it takes the daylight with it, a curtain on a door that swings never hangs right, and blinds on a door that opens thirty times a day rattle themselves loose. Smart glass front doors settle it by moving the privacy into the glass. Optically clear when you want the light and the view down the walk. Evenly frosted, edge to edge, about a second after you touch a switch.
See out without being seen
The doorbell moment is the one that sells this. Somebody rings, and in that half-second between the sound and you reaching the door, a clear entry lite has already shown them your hallway, your stairs, your alarm panel, and whatever is stacked by the console table. Frosted, it shows them a silhouette.
Be clear about what the frosted state is and isn't: it scatters light in both directions, so it is not a one-way mirror, and you'll see shape and movement rather than a face. What it does do is take the sightline out of the equation for both of you until you decide otherwise — and because the frosted state scatters rather than blocks, the entry keeps its daylight instead of going dark like a covered door would.
The default matters just as much. Switchable glass is clear only while it's powered, which means frosted is the fail-safe state. Power cut, tripped breaker, transformer unplugged by a contractor — the door goes private, not exposed. Privacy is what happens when nothing is working.
Film on the lite you have, or a new sealed panel
Most of our entry work never touches the door. Switchable smart film (PDLC) is measured and cut to the door lite, then applied to the interior face of the existing glass. The slab, the lockset, the hinges, the weatherstripping, and the exterior face all stay exactly as they are, the film sits out of the weather, and a typical single-door entry is a one-day job in a finished house. The technology is identical to a sealed panel; it's delivered as a retrofit instead of a rebuild. Our guide to smart film covers the material and its frosted finishes, and the blog post on whether you can put smart film on a front door walks through the same question from the research side.
If the door is being replaced anyway, or specified new, the better route is laminated smart glass — the PDLC layer sealed between two sheets of glass under heat and pressure, with two low-voltage leads at the panel edge and no surface layer at all. We fabricate panels to size in Canoga Park and set them like any other glass unit. The rule of thumb is simple: keeping the door means film, changing the glass means a sealed panel. Either way it's the same smart glass installation crew and the same controls.
Sidelights and transoms
An entry is rarely just a door. Narrow sidelights flank it, a transom runs above it, and on modern LA houses there's often a full glazed panel next to the slab that's bigger than the door itself. Those are usually the real privacy leak — they sit at standing eye level, they don't swing away, and nobody thinks to cover them.
They take the same product and the same wiring. In practice we tie the door, its sidelights, and the transom to a single circuit so the whole opening changes state together on one press, because switching a door and leaving the panel beside it clear defeats the purpose. Where a client only wants the sidelights done, that works too — each panel can carry its own channel.
Safety glazing at the entry
Glass in a door, and glass within a set distance of one, counts as a hazardous location under the building code, which is why that lite is already tempered or laminated in nearly every house we walk into. Retrofit film doesn't change that: it's applied to the face of glass that stays exactly what it was. When we supply new panels, laminated smart glass is itself a safety glazing — two sheets bonded around the switchable interlayer, so a broken pane holds together rather than coming apart. What none of this is, and we won't dress it up otherwise, is a security product. It changes what people can see, not what a door can withstand.
Real front-door installs across LA
- Beverly Hills modern entry — 65 sq ft of PDLC switchable film applied to the existing glazing of a full-height entry door on a new custom home, wired to a wall switch set discreetly inside the foyer so the architect's front elevation was left alone.
- Pasadena front door and balcony — 140 sq ft total retrofitted across a full-glass front door and the balcony panel beside it. The owners had been stepping outside every evening to draw outdoor curtains; now a wireless remote does it from indoors.
- Rowland Heights two-story foyer — 31 sq ft cut to one tall entry lite sitting behind an ornamental wrought-iron scroll grille. Handheld remote only, so nothing was cut into the entry paneling, and the finish was specified for a west-facing door.
- La Cañada Flintridge entry upgrade — switchable film applied straight onto the existing front-door glass panels, clear to frosted at the press of a button, with the wiring run in so the entry needed no blinds or coverings at all.

What it costs
Entry doors price on the glass area, how many separate panels are switched, the control you pick, and how hard it is to get power to the jamb. A single door lite is one of the smaller jobs we do; a door plus two sidelights and a transom is four panels and four connections. The useful anchor is that a small switchable panel starts around $1,500 fully installed and scales with size, and retrofitting film onto glass that's already in the door avoids the cost of new glazing entirely. The full breakdown, with no bait numbers, is on our smart glass cost page.
