We're United Builders

United Builders installs Anlin windows and doors across Southern California. As a General Contractor and glazing contractor, so we can take on the projects other companies have to pass off or walk away from. That includes carpentry repairs, new headers, drywall, stucco, resizing openings, and Skywall-style feature installs. If your goal is a more comfortable home with windows and doors you can rely on, we deliver a clear plan, clean finish work, and a single team accountable from start to final walkthrough.

Services

United Builders provides full-scope window and door replacement for Southern California homeowners who want the job done right the first time. Homeowners choose United Builders for an owner-led process, HOA experience, and workmanship that delivers a clean finished look and long-term reliability.

Window Installation & Replacement

United Builders installs Anlin replacement windows with an owner-led process that focuses on consistent sightlines, balanced layouts, and the features that your home needs. When older windows come out, it’s common to find uneven openings, worn trim conditions, or wood that needs repair to achieve a clean finish. As a licensed General Contractor and glazing contractor, United Builders can handle the carpentry and finish work in-house, so the project stays on track and the final result looks uniform, not patched in.

Door Installation & Replacement

United Builders installs Anlin replacement doors with careful attention to fit, alignment, and long-term operation, including the surrounding surfaces that affect performance over time. If a door opening needs structural attention, threshold work, or exterior and interior finish repairs, United Builders can complete that scope without handoffs, which reduces delays and improves accountability. The result is a door that feels solid, secure, and finished, not “installed and left for someone else to fix.”

Why Choose United Builders?

United Builders brings the planning, execution, and accountability to make the investment feel finished, straightforward, and worth it.

We are a licensed California contractor with both General Building and Glazing classifications under CSLB license #841148. That experience and knowledge matter when your project moves from a simple swap to something bigger.

If the opening needs attention, we can complete the scope in-house without the need for subcontractors or lengthy delays.

The product matters too. We only install Anlin- a California-based replacement window and door manufacturer. Their products are backed by a Double Lifetime Warranty that covers parts and labor, and is transferable to the next homeowner.
