We build the window. We install it too.
Alam Windows & Doors is a California vinyl window manufacturer serving homeowners, general contractors, and developers — from standard units to specialty shapes — with the same process, the same standards, and the same accountability on every project.
Alam Windows & Doors was founded in the Inland Empire to fill a gap that contractors kept running into: a vinyl window source that controlled its own production, held AAMA and NFRC certifications, and could handle specialty shapes without a six-week lead time.
Because we manufacture in-house, every unit that leaves our floor is code-compliant from day one — not assembled from third-party components we cannot verify. Precision starts at the machine, not the job site.
Manufactured here. Installed by us.
That foundation lets us serve a homeowner ordering two bedroom windows and a developer spec-ing a 200-unit tract with the same process, the same documentation, and the same accountability.


Installation is half the window.
A window that leaves our floor to spec and gets installed incorrectly is still a failed window. That is why our crews handle both — the manufacturing and the field work — so responsibility never gets split between two vendors.
From arch windows in a custom gable to standard single-hung units in a new tract, the sequence is the same: manufactured to AAMA and NFRC standards, installed by our own team, verified before we leave the site.
Architectural shapes — trapezoids, arches, circular units — are not special orders that require extra lead time. They are part of our standard production capability.

Whether you are a homeowner with two windows or a contractor with a full tract spec, the quote process is the same — direct, documented, and contractor-grade.
