Based in Lake Elsinore, Riverside County, Astrum Construction holds California contractor license #1107070, classified B (General Building, C17 Glazing). The license was active and clear when this listing was compiled.

Window and door contractors replace failed or single-pane units, install new openings in existing walls, and fit entry and patio doors — including the flashing, sealing and interior finish that make the installation weathertight.

Working in southwest Riverside County: A lot of newer neighborhoods here sit under HOA architectural review, which adds an approval step before exterior work can start.

Before you hire any window or door contractor: Ask for the U-factor and SHGC of the windows quoted. California’s Title 24 sets requirements by climate zone, and these two numbers are how replacement windows are actually compared.

License status can change at any time. Confirm license #1107070 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
