If you’re planning window installation in Los Angeles, two questions come up more than any other: do you need a permit, and when’s the best time of year to do it? At Beyond Builder, a licensed general contractor (LIC #1118371) serving Los Angeles and Southern California, we handle window installation as part of home remodeling projects of every size — here’s what you need to know before you start.
In most cases, yes — a permit is required for window installation in Los Angeles when the project changes the size of the opening, affects a structural wall, or is part of new construction.

As for timing, spring and fall are generally the best windows of the year for installation in Los Angeles, thanks to mild temperatures that make the work easier and help new seals cure properly — though our mild climate means installation can reasonably happen almost any time of year.

If cost is a factor, we also offer flexible financing with no home equity required.
