West Hills Windows & Doors
Window and door replacement on older West Hills houses, done in a set order: measure, order, protect, then one opening at a time from removal to paint.
On an older West Hills house, window replacement follows a fixed order. Every opening is measured and photographed, the units are ordered, and nothing comes out of a wall until the new ones are on site. Then each opening is worked from start to finish before the next one is opened: old unit out, framing repaired, flashing set, new unit in, trim back on. Original casing and sills go back where they came from.
Before anything is removed
Furniture is moved back from the walls, floors are covered from the door to the window, and a dust wall goes up when plaster will be cut. Paint on older trim is tested for lead before it is disturbed, and if the test comes back positive, the work follows lead-safe practice with plastic sheeting, misting and a HEPA vacuum. Casing that will be reused is scored along the wall line, pried off in one piece and numbered on the back, so it returns to its own opening.
Closing each opening
Once the old unit is out, the rough opening is checked for level and plumb, and any rot at the sill framing is cut back to sound wood. The sill pan and side flashing go in, the new window is set on shims, and the gap around it is filled with low-expansion foam. Exterior trim or stucco patching follows, then the numbered casing goes back inside. Paint and caulk come last, after a final check that every sash opens, closes and locks as it should.

Windows & Doors in West Hills: common questions
Repair when the joints, the sill and the glazing rabbets are sound, even if the paint is worn and the cords are broken. Those are routine fixes. Replacement makes sense when the sill or lower sash has rotted through, or when the frame has racked so far that the sash can no longer be fitted to it.
Matching starts with the width of the frame as seen from the street, the height of each sash and the grille pattern. New units are ordered to those proportions in wood, clad wood or fiberglass. If the house has sill horns or a deep interior stool, those are kept or rebuilt in the same shape around the new window.
Permits for West Hills come from LADBS, the City of Los Angeles building department. The application carries a window schedule listing each unit's size, its U-factor and solar heat gain figure, and which panes are tempered. Those numbers are checked against state energy limits. We draw up the schedule from our measurements, so the permit matches what is ordered.
