About Us

Your Source for Specialty Window & Door Installation in Orange County, throughout California and nationwide.

MISSION: To provide high-end window and door installation while providing superior customer service

Since 2004, Ultimate Installz, Inc. has built an exceptional reputation as a leading window and door installation company in Southern and Northern California. Our reputation has superseded us and we now travel both nationally and internationally to provide installation of windows and doors on custom homes and commercial buildings.

Jayson Cruz, owner and founder of the company, brings over 26 years of experience in the industry. He has spent significant time working with custom door manufacturers to ensure he is fully educated on the newest techniques, latest products, and stays ahead of the window and door industry.

While our list of services is extensive, and includes service and repair, door and window automation's and yearly maintenance packages; our true specialty is the installation of custom windows and doors. Who we work with is not limited, but does include many architects, general contractors, window & door manufacturers, window & door suppliers, and homeowners.

Our primary goal is to provide excellent customer service, and the most superior workmanship. Our commitment to our customers is so high, that we not only offer a 10 year (limited) water infiltration warranty, but we also have an on-call team available day and night for emergencies. Our team focuses on attention to detail, cleanliness, timeliness, and doing what it takes to get the job completed as quickly as possible. We understand that there are always hiccups in building, but we work diligently to keep the job running smoothly from beginning to end. Ultimate Installz works with many of the leading window & door manufacturers; just contact us and we can help!
