If your windows are original, you are paying for them every month anyway
Single-pane and early aluminum windows conduct heat straight through the frame. In Southern California that shows up as a west-facing room nobody uses, an air conditioner that never cycles off, and a utility bill that keeps climbing. Replacing them is the one home upgrade that pays you back every month you own the house.
Rooms you can finally use
Low-E glass rejects the heat that turns a west-facing bedroom into an oven from 2pm onward, without making the room dark.
An AC that cycles off
When the envelope stops leaking, the system stops fighting the sun. That is where the utility savings actually come from.
A quieter house
Dual-pane glass with a proper seal takes the edge off freeway noise, leaf blowers and the neighbour’s dog.

How it works
Four steps, no surprises
You will know the price, the timeline and the method before anything is ordered.
Our own crews do the installation — the people who quote your job are connected to the people who fit it.
Free measurement & written quote
We come out, measure every opening, check the condition of the frames and stucco, and hand you an itemized written price. No obligation, no same-day-only pricing.
Design & approval
You pick styles, grid patterns, frame color and glass package. We confirm HOA requirements and pull the permit. Then we order — built to your exact measurements.
Manufacturing
Your units are custom built. Production is typically 4–6 weeks. We keep you updated instead of making you chase us.
Installation & cleanup
Most whole-home installs finish in 1–2 days. We protect floors and furniture, seal and finish every opening properly, haul away the old units, and walk the job with you before we leave.

What’s a realistic budget for 11 windows in Fullerton?
For 11 standard-size vinyl windows retrofitted into sound stucco openings, most Fullerton homes land around $6,500–$11,000 installed. Full-frame replacement runs higher. Want me to put a free measurement on the calendar so you get an exact number?

Pick your city for local pricing notes, permit requirements and the window styles that suit the housing stock there.
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.
Coverage depends on the product line you choose, so we spell it out in writing with your quote. That way you can compare it line by line with any other quote you get, instead of relying on a verbal promise.
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.
