Welcome to United Builders!

Welcome to United Builders. We are a general building contractor, specializing in the installation of custom, vinyl and dual-paned windows and doors. We serve Southern California - particularly the Inland Empire.

So what makes United Builders special? Most companies must pass their advertising costs and commissions to the customer to recoup expenses. Because we pay no sales commissions or hefty advertising expenses, we can save you as much as 20-50% over our competitors for the exact same products! Rest assured, we sell and install only high-quality, energy-efficient products - not low-grade builder materials.

Our goal at United Builders is to provide you with high-quality products, professional and courteous service, and a generally pleasant experience - after all, YOU are our best form of advertising! United Builders offers window replacement services in southern California, including the Inland Empire. If you are looking to replace your windows or doors, look no further than United Builders.
