Most vinyl window projects we quote land between roughly $600 and $1,200 per window installed — and the per-window number comes down on larger jobs, because a crew that is already set up at your house is more efficient on opening twelve than on opening one. Where you land depends on size, style, glass package and how the window is attached to the house. A retrofit installation into a sound stucco opening sits at the low end; a full-frame replacement with new trim and stucco patch sits at the high end. Oversized units, custom shapes and moving glass walls are quoted individually. We give you a written, itemized number before any work is scheduled — no ballpark that changes later.

The estimate is free and there is no obligation. We measure every opening, walk you through the options that actually apply to your house, and leave you with a written quote. We do not run a same-day discount that disappears when we leave.

Custom windows are manufactured to your exact measurements, so production typically runs about 4 to 6 weeks after you approve the order. The installation itself is usually 1 to 2 days for a whole-home project, and a few hours for a single patio door. We clean up and haul away the old units the same day.

Our vinyl windows carry a Full Lifetime Warranty that includes glass breakage — which is unusual, and it is the part most homeowners care about. If a pane breaks, it is covered. Frames, welds and hardware are covered for the life of the product.

Our windows and doors are engineered to meet or exceed ENERGY STAR standards in all climate zones and meet California Title 24. That makes them eligible for state and federal energy tax credits and for most utility rebate programs. We give you the NFRC labels and documentation you need to file — confirm current credit amounts with your tax preparer, since the programs change.

In most Southern California cities, yes — window and door replacement is a permitted job, and egress and safety-glazing rules apply to bedrooms, bathrooms and anything near a door or floor. We handle the permitting process as part of the project so it is inspected and legal.

Yes. Every window is tested by AAMA and NFRC and is ENERGY STAR approved and rated. Every unit ships with its NFRC label showing U-factor and Solar Heat Gain Coefficient so you can verify exactly what you bought.

No. Every window is custom made to your home’s exact specifications for a perfect fit at no extra charge and no extended lead time. We do not make your house fit a stock size.

We serve Los Angeles County, Orange County, the Inland Empire and Las Vegas. If you are near the edge of that map, call and ask — we travel for larger projects.

Retrofit (block-frame) installs the new window into the existing frame and is faster, cleaner and less expensive — the right choice when the existing frame and stucco are sound. Full-frame replacement removes everything down to the rough opening, which is what you want when there is water damage, dry rot, or you are changing the size or style of the opening. We tell you which one your house actually needs after we look at it.
