Mission Hills Windows & Doors, Read from Behind the Stop

Mission Hills window and door work that starts by pulling an interior stop to see how each frame was fastened, then specifies an insert or a full frame.

One interior stop comes off a Mission Hills window before we price anything. Behind it we can see how the old frame was fastened, whether a nailing fin runs under the stucco, and what the wood at the sill looks like. That single look tells us if the window can take an insert or needs the full frame out. The stop goes back on before we leave, and what we saw goes on the scope.

What sits behind the stop

A metal window with a nailing fin was set before the stucco went on, so its fin is locked under the plaster. That frame can stay and host an insert if it is straight and dry. A wood frame shows its condition at the sill and the lower jambs, where water gathers. We look for dark grain, loose joints and old sealant packed over a gap. If the space between the frame and the stud is open, we check for building paper and whether it was lapped or torn. Each finding is noted against that opening.

Turning one look into a scope

The stop tells us which path each window takes, and the scope follows it. An insert in a sound frame gets tempered dual-pane glass and new interior trim. A frame with rot or torn paper comes out, the sill is rebuilt, and a sloped pan with taped flashing goes in before the new unit. Doors get a similar look under the threshold and at the base of the jambs. Mission Hills sits inside the City of Los Angeles, and when the work needs a permit, LADBS issues it and inspects the flashing before trim covers it.
