Welcome to United Builders!

We are a General Contractor, not just a window installer, so we do the jobs other companies don’t want to do. For example: carpentry (replacing rotten wood), new headers, drywall , stucco, skywall windows , opening up walls,  and reducing/enlarging window sizes. If you don’t want to continue to pay high energy bills & don’t want to overpay for new windows, then United Builders can give you all the benefits of highly energy efficient windows at better prices than our competitors. How do we do that? We are a family owned company with 19 years in business, without the huge advertising costs. We don’t pay the industry average of 15-20% sales commission, since the owner gives all estimates himself. Read our nearly 500 reviews on Home Advisor.

Beautiful windows that cut down heat and noise from outside. Well worth the investment. Had 2 sliders and 20 windows replaced. Get so much more light in the house with these tinted windows as compared to the old tinted single pane windows I previously had.

Just completed a 19 window install job at our home.  Excellent service, no non-sense estimate and quality CLEAN installation.  Workers are great courteous people (foreman is so-so). Highly recommend. Prices were 25-35% better than other estimates.

The last couple of years drastically changed our day-to-day lives. From Zoom calls to endless sanitation and disinfection, we now experience many different things that are the "new normal." While we were all hanging out a home, many homeowners used the extra time to turn their remodeling visions into reality. One project that became pretty popular was replacing or upgrading windows. With many window replacement projects came several new window trends. Check out our latest blog for more details at https://unitedbuilders.info.

Bay windows are specialty windows comprised of three windows that project out from the wall. Each window section is typically joined at 30 or 45-degree angles. The center window panel is often larger than the side windows and is generally fixed. Bay windows can add beauty to any southern California home so if you’re looking to make a fine upgrade, consider a bay window. Visit https://unitedbuilders.info or call (909) 969-8976.
