“The sliding glass door replacement I recommend for most Valley homeowners: a multi-panel pocket slider that stacks completely out of sight. Standard 6-foot sliding doors are fine for a bedroom; for a living room-to-patio connection, a 12–16 foot opening that opens completely transforms the relationship between indoor and outdoor space. The price difference is $8–15K but creates a fundamentally different room.”
Specify tempered glass in all hazardous locations: windows within 18 inches of the floor, within 5 feet of a tub/shower, in glass doors, and in sidelights adjacent to entry doors. Tempered glass shatters into small, relatively safe pieces rather than large shards. This is a code requirement, not an option; confirm it's in the specification.
The most common window & door replacement mistakes in North Hollywood are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
