In Gilbert, where sunny days stretch across nearly the entire year, your windows play a major role in keeping your home cool and efficient. L.J. Neal & Sons is the trusted name for heat-stopping window and patio door replacement across Arizona, including their high-quality L&S windows. Our team provides locally made products that outperform standard dual pane glass and help homeowners control indoor temperatures even in peak summer months.
With over seventy years of experience and five years serving Arizona, we understand exactly what homes in Gilbert need. Our Extreme Series triple pane windows, including the L&S windows, are designed for the desert, tested in the desert, and installed by Arizona professionals who know the challenges of this climate.
From Power Ranch to Seville, our windows, including the innovative L&S windows, help homeowners reduce energy costs and enjoy a cooler, quieter living environment every day.

Gilbert’s summer heat can turn any room into a sauna when windows aren’t built for desert weather. Ordinary glass allows UV rays and infrared heat to pass directly through, causing higher cooling costs and uneven temperatures.
Our Extreme Series triple pane windows are engineered specifically for Arizona’s conditions. Three insulated panes work together with low emissivity coatings to block up to 98 percent of heat transfer. You still get bright, natural light, but the heat stays outside.
Each window is manufactured locally in Arizona using materials proven to last through long summers and sudden monsoon humidity. Homeowners from Agritopia to Val Vista Lakes choose our windows for their performance, comfort, and design.
Better insulation means your air conditioner runs less often, your rooms stay balanced in temperature, and your furniture is protected from fading caused by harsh sunlight.
Patio doors are one of the biggest heat leaks in any Gilbert home. Our L&S Windows triple pane patio door systems address this issue using the same advanced technology found in our window line.
Each installation is handled by certified professionals who ensure a tight seal and precise fit. The result is a door that glides smoothly, looks beautiful, and keeps hot air out even during 115-degree afternoons.
Whether your home is near Santan Village, The Islands, or South Gilbert, our patio doors from L&S Windows help maintain comfort and efficiency all year long.


Every product we install is made right here in Arizona, supporting local jobs and families. When you choose L.J. Neal & Sons, you are investing in craftsmanship that reflects the strength and pride of our state.
Our windows are tested in the same harsh conditions they are built for, ensuring long term performance against heat, dust, and sun exposure. They are designed to look great, function flawlessly, and withstand Arizona’s toughest seasons.
