Valley Village Windows & Doors Flashed from the Head Down
Valley Village windows and doors flashed from the head down, with drip caps, sloped sill pans, threshold pans and clear weep slots that keep water outside.
Much of the water that ends up inside a wall near a window arrives from above, running down the face and slipping behind the frame at its head. On a Valley Village house, the head of each new window gets taped flashing tucked under the weather barrier, and a drip edge where the wall is stucco. Under the window, the sill pan catches anything that gets past and returns it outside, so a hard storm on an inland lot runs off the wall.
Starting at the head
Above each opening, the weather barrier is slit and folded up so the head flashing can go on first. The flashing covers the top fin, and the barrier is folded back down over it, so water coming down the wall keeps to the outer face. On a full-frame replacement in stucco, a drip cap or casing bead above the window gives the new plaster a clean edge to shed from. A retrofit insert relies on the old head flashing, so we look for staining on the wall above the window before choosing that path.
Sills, doors and the patio
At the bottom, a sloped pan lies under every new window, turned up at the back and the ends. The lower fin is left free of tape so trapped water can drain. Doors sit lower and see more water, so a threshold pan reaching past the wall goes under each door we replace. A slider track has weep slots that are cleared before sign-off. If a patio slab tilts toward the house, that is noted on the scope as separate work, since water pooling at a threshold wins in the end. LADBS handles any permit the work needs here.
Windows & Doors in Valley Village: common questions
Whether the wildfire glazing chapter applies depends on the state hazard maps, and the Valley Village parcel is checked against them before anything is ordered. A mapped parcel needs units whose inner or outer sheet is tempered, with glass block and rated windows as the fallbacks. Every new unit, mapped or not, sits on a sloped pan with flashing lapped from the head down.
Retrofit leans on whatever flashing already sits behind the old frame. If there is no staining above or below the window and the sill is dry, an insert can go in. Signs of water mean full-frame, so the head flashing and the pan can be redone and folded into the barrier.
Any window or door with water staining, a soft sill or a rusted track leads, since a leak keeps working on the framing. Doors with worn thresholds follow. Sound, dry openings can wait for a later round, which the scope prices on separate lines.
