United Builders provides window and door replacement in Southern California for homeowners who want clear communication and one accountable team from start to final walkthrough. We replace aging, drafty, and hard-to-operate units with upgraded windows and doors that improve comfort, reduce unwanted air leaks, and bring a cleaner, more consistent look to your home.
We install Anlin products and bring General Contractor capability to projects that need more than a basic swap, including carpentry repairs, headers, drywall, stucco, and opening adjustments. If your project requires carpentry or finish repairs once the old unit comes out, we can handle that scope in-house under our General Contractor and glazing licensing, so the job stays on track.
Homeowners choose United Builders for an owner-led approach, strong communication, HOA experience, and workmanship that holds up well beyond install day.
Window replacement is the right choice when your existing windows are drafty, difficult to open, noisy, or no longer seal correctly. United Builders replaces old windows with careful measurement, clean installation, and finish work that matches your home for a consistent exterior appearance, a cleaner interior trim line, and windows that operate smoothly every day. We pay attention to the practical details like alignment, smooth movement, clean transitions at the opening, and a finished look that doesn’t feel “patched in.”
Replacement projects can also uncover common conditions behind the old frame, especially in older homes or homes with older installations. That can include worn wood at the sill, uneven openings, tired trim, or surrounding surfaces that need repair for a truly clean finish.
Because United Builders is licensed for both glazing and General Building work, we can complete carpentry and related finish repairs without handing the project off to another contractor. That reduces delays, keeps accountability in one place, and helps ensure the final result looks intentional across the home.
Window installation applies when you’re adding a new window, changing the size of an opening, or updating the window layout as part of a remodel. This is common when homeowners want more light in a living space, improved ventilation in a kitchen, or a better-balanced exterior elevation.
United Builders can manage the scope that comes with new or altered openings, including the structural and finish work required to make the result look like it belongs. That includes proper framing support, clean interior finishing, and exterior patching where needed. For HOA communities, installation planning also matters for consistency and approvals, especially when changes affect the street-facing elevation.
Window and door replacement is finish work. The difference shows in clean lines, consistent trim, smooth operation, and a final look that feels intentional across the whole home. United Builders installs with experienced master carpenters who focus on the details the first time, so the result looks right from the curb and feels right day to day.
We are also equipped for projects that require modifications. Opening enlargements or reductions, window-to-door conversions, relocation of openings, and the drywall or stucco work that comes with those changes can be completed under one contractor. That keeps the scope clear, reduces delays, and delivers a cleaner finished result.
Our licensed company is a family oriented general contractor, who specializes in professional window and door replacement. Unlike other companies who claim to offer discounts, we pass special savings to our clients because our business gets personally involved with each and every sale. We charge no commission to pay or hefty fees for advertising expenses. This allows us to pass these savings along directly to our clients. What do the savings mean to you?
