La Verne Windows & Doors, Measured in Glass
La Verne window choices measured on the first visit: how much glass an insert gives up next to a full-frame unit or a restored sash, opening by opening.
How much glass does an insert window give up? When that comes up at the first site visit in an older La Verne house, a tape measure answers it on the spot. We measure the visible glass of one window, then take off the new frame and sash an insert would add inside the old frame on every side. On a small window the loss is plain to see, and the comparison shapes the method we propose.
Glass lost and glass kept
With an insert, the room stays tidy: the original frame, inside casing and plaster are left where they are, and the new unit slides into the old pocket. The trade is a border of new frame and sash around the glass. Full-frame work strips the opening back to studs, so the new unit fills it and its glass stays near the original size, and the opening can be flashed properly from the framing outward. A restored sash keeps every bit of its glass. Each window's visible glass under all three methods goes on one sheet.
Bedrooms, small windows and doors
Small windows lose the most to an insert, so they lean toward full-frame work or restoration. Large windows in sound frames can take an insert with little change in light. Bedroom windows need a closer look, because they are escape openings, and the code relaxes the size rules for a replacement only if no bigger standard size would fit the existing opening. We measure each clear opening before choosing. Exterior doors raise the same question in another form: a sound frame can take a new slab, and a failed one calls for a prehung unit.

Windows & Doors in La Verne: common questions
A sound original wins on glass, since restoration loses none of it. If the wood is firm, the sash is reglazed, hung on new cords and sealed against drafts. Where the frame has rotted, a full-frame unit holds the glass close to its first size, which an insert set in that frame would shrink.
An original sash sits back from the face of its frame, which casts a shadow line around the glass. An insert set flush with the old frame loses that depth. We measure how far each original sash is recessed and choose units with a similar setback, along with the same sash proportions and bar layout.
A permit for this work comes from the City of La Verne building division. Its reviewers look at headers where an opening changes, escape openings in bedrooms, energy labels on new glass and safety glazing near doors. Restoring a sash in place is repair work. Our side covers the forms and every site visit with the city inspector.
