La Canada Flintridge Windows & Doors, the Patio Question

Will a wider door mean a new patio? La Canada Flintridge thresholds, slab heights, drain channels and fire-aware glass, reviewed by the city.

Does the patio have to be rebuilt along with the door? Ask that early when a La Canada Flintridge wall is being measured for wider glass. The answer hangs on the height of the slab outside, the depth of the new threshold and the direction rain will run. Often a new door can meet the slab as it stands, with a drain channel doing the extra work.

Slab height and the threshold

A flush threshold only works if the slab outside sits a little lower than the floor inside and falls away from the house. A level and a tape settle this at the visit. If the slab is too high, the choices are a stepped sill, a drain channel cut along the door line, or reworking a strip of concrete beside the wall. We price those paths separately, so the patio is touched only when the door truly needs it. Photos of the slab edge go with the quote, so the choice is easy to review at home.

Mapped parcels and the permit

A La Canada Flintridge parcel can land on the fire hazard map, and when it does, the glass, vents and trim around a new opening may need to hold off embers. We check the parcel before anything is ordered, which means those rules are known before the wall is open. Beam and glass are reviewed by the building department serving the city, and tempered panes keep their etched labels for the inspector. The hazard result goes on the quote beside the glass type each rule calls for.
