About Us

Our Story

With a USC degree and 15 years of carpentry and general construction knowledge and experience I  opened Seaport Windows and Doors in 1991 at 4201 Katella Ave., in the city of Los Alamitos.  Back then it was just my wife Lisa and I, marketing with flyers down the local streets, meeting our neighbors and selling, installing, servicing and generally doing it all as a small local window and door store.

Twenty six years and three children later Seaport Windows and Doors is still going strong and stands tall in the window and door replacement industry.

With install crews, a warehouse manager, and an office and sales staff Seaport Windows and Doors has grown to become a respected industry leader in the sales and installation of replacement windows and doors.

MILGARD, JELD WEN, PLY GEM, IWC, IWP, PLASTRO, EMTEK, and BALDWIN are just some of the manufacturers we sell, install and service.

Straight replacement windows and exterior doors, new construction windows and doors, full front elevation face lifts and re-designs as well as cut downs, build ups and new window locations are all items within the installation/building capability of Seaport Windows and Doors.

With product development a main focus at Seaport, we have developed and are now building and installing the “ULTIMATE” door and the “ULTIMATE” window.  Exterior Bi folding doors and windows in a myriad of design layouts that blend form and function to create an unsurpassed blend of indoor and outdoor living, and really grey the line between interior and exterior space.

What’s next?  Only time will tell.  These are exciting and changing times and at Seaport Windows and Doors we are always on the cutting edge.  Come pay us a visit, or explore our website and experience the “ULTIMATE” door and window, you will be hooked.

We look forward to meeting you and working with you on your window and door project.
