Lake Balboa Windows & Doors, Dry From Head to Sill
Gutter diverters, kickout flashing, metal head caps, open weeps and sloped landings keep water off the doors and windows of older Lake Balboa houses.
A door sits at the bottom of the wall, so rain that runs down the face of an older Lake Balboa house collects at its threshold. Keeping that spot dry starts at the roof edge. A gutter or diverter moves water off the door head, a metal cap sheds it past the trim, a pan under the sill sends anything that gets in back outside, and a landing that falls away carries it off.
Roof edge to door head
An overflowing gutter above an entry drops its water straight onto the head trim, where it finds the joint between casing and wall. Pitching the gutter toward its downspout, or adding a short diverter on the roof edge, moves that stream to one side. Where a lower roof dies into a wall beside a door, a kickout bent at the lowest piece of step flashing turns water into the gutter so it never runs down the siding. Over the casing, a painted metal cap slips up behind the building paper and bends out past the trim, so drops fall clear.
Weeps and the landing
Modern frames drain their sill tracks through small weep slots on the outside face, and a bead of caulk across those slots traps water inside. They are left open and checked at the final walk. Outside a patio door, the landing should slope away from the threshold. A slab that tips toward the house can be ground, replaced, or fitted with a channel drain along the door that empties into the yard. When the slab has to stay, a taller threshold is another answer, provided the step down remains within what the code allows at an exterior door.

Windows & Doors in Lake Balboa: common questions
Read the water marks. A bottom rail and sill that are firm under worn paint can be restored with new putty and paint, and the original sash stays. Wood that gives at the sill, or staining on the wall below the window, means the frame should come out so a pan and new flashing can go under a replacement.
We photograph each window from outside before it is touched and note its frame width, its sash split and where the bars fall. The new unit follows those notes in a finish chosen for the trim, and the metal cap over the head is bent to sit on the original casing, so the opening looks as it did.
Lake Balboa is a City of Los Angeles community, so LADBS reviews the permit. New units carry energy labels, and an opening that changes size needs its framing shown on the plans. A gutter diverter or a new drip cap is generally ordinary repair work that falls outside the permit.
