Surrounded by mountain views and desert air, Fountain Hills homes experience some of Arizona’s most intense sunlight. When older windows let in that heat, it not only affects comfort but drives up your energy bills. L.J. Neal & Sons offers heat stopping window and patio door replacement designed for the challenges of desert living, including their innovative L&S windows.
Our Extreme Series triple pane windows, including L&S windows, are built and tested in Arizona, combining advanced technology with more than seventy years of experience. These locally made systems keep the heat outside, protect your interiors, and help maintain balanced indoor temperatures even during the hottest months.
Whether your home overlooks Fountain Park, sits near Shea Boulevard, or rests on the hillsides with a desert view, our L&S windows are engineered to perform where you live.

In Fountain Hills, sunlight is both a feature and a challenge. Dual pane windows can only do so much to control heat transfer, often allowing up to 40 percent of solar energy into your home.
Our Extreme Series triple pane windows use three layers of insulated glass and advanced low emissivity coatings that block up to 98 percent of UV and infrared heat. You can enjoy the natural light and stunning views without the uncomfortable heat gain.
Every window is manufactured locally with materials designed to handle Arizona’s dry heat and sudden temperature shifts. From homes near Eagle Mountain to neighborhoods around Palisades Boulevard, homeowners notice lower energy costs, cooler rooms, and greater year round comfort.
Our windows also help protect furniture, flooring, and decor from fading caused by the strong Arizona sun.
Patio doors are a focal point in many Fountain Hills homes, but they are also a significant source of heat intrusion. Our triple pane patio door systems at L&S Windows use the same technology as our windows, effectively sealing out heat while maintaining smooth operation and clear views. Each installation is completed by certified professionals who take precise measurements to ensure every frame is perfectly sealed. Homeowners consistently report noticeable improvements in temperature control and noise reduction after replacement. From Golden Eagle Boulevard to Sunridge Canyon, Fountain Hills homeowners rely on our L&S Windows team for patio doors that perform as beautifully as they look.


Every window and patio door from L.J. Neal & Sons is built locally by Arizona workers who know the challenges of this climate. Choosing our team means supporting local jobs and investing in products created for desert performance.
