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.

Bow windows are a gorgeous addition to any home! They create the illusion of more space in your home while providing great views of the outdoors. These elegant windows extend out from the home, allowing room for more windows and additional natural light; both elements combine to make a room feel larger than it actually is. Are these the types of windows you're looking for? Start your someday project today by visiting our website https://unitedbuilders.info or calling us at (909) 969-8976

One of the biggest benefits of sliding panel doors is that they provide better access to backyard and patio spaces, and they have better functionality than old broken-down sliders or French doors. These modern sliding door panels are built to glide easily within the frame. That means that anyone can use them with ease, from small children to seniors with arthritis or other issues that make gripping a door handle and turning it, like the handles on French doors, difficult.
